Description

H Ü L L E

The present invention relates to a sleeve provided for storing at least one flat information carrier, in particular at least one compact disc blank or at least one (re) writable compact disc (CD) or digital versatile disc (DVD), the other of which Edges are closed and which has at least one outside and at least one inside arranged opposite to the outside.

Such covers are known for flat information carriers, in particular for compact discs (CDs) or digital versatile discs (DVDs) provided with acoustic information and / or with optical information. The outside of these conventional covers is made of (strong) paper, cardboard or cardboard; the inside has a paper coating, which is usually glued to the (strong) paper, the cardboard or the cardboard.

The aforementioned, commercially available cases offer for described or recorded Information carriers, in particular for described compact discs (CDs) or digital versatile discs (DVDs), provide somewhat reliable protection; However, it is a question of an as yet unwritten and therefore particularly sensitive information carrier on its surfaces, such as a not yet described compact disc (= so-called compact disc blank) or a (re) writable compact disc (CD) or digital versatile disc ( DVD), to keep them safe and to protect them from damage of any kind, the known covers have proven to be disadvantageous in that, for example, when the information carrier is removed from the cover, the paper coating on the inside of the cover facing the information carrier loosens fibers and the Contaminate information carriers.

Such fibers also cause small scratches and scoring when the information carrier moves relative to the envelope, i.e., for example, when the information carrier is removed from the envelope or when the information carrier is inserted, by external scratches and scratches, i.e. external damage to the sensitive surfaces of the information carrier, so that this is unfortunately unusable, which is undesirable from both a financial and ecological point of view; in the case of a (re) writable information carrier, such contamination and / or damage can even result in data loss, which can of course have unforeseeable consequences. Based on the disadvantages and inadequacies set out above, the object of the present invention is to provide a cover which can be used flexibly on the one hand and on the other hand ensures effective protection of the information carrier from damage caused by abrasion and from contamination caused by fiber fly.

This object is achieved in a case according to the preamble of the main claim in that, according to the teaching of the present invention, the outside has at least one plastic film, that the inside is at least partially provided with at least one plastic fleece, that the plastic film and the plastic fleece lie flat against one another and that the plastic film and the plastic fleece are connected to one another at least point by point, at least linienfor ig and / or at least in areas.

The provision of a plastic film on the outside of the cover and a plastic fleece on at least parts of the inside of the cover yields the advantage which is surprising for the person skilled in the art that the cover can be produced by machine much faster than a conventional cover. For example, the parts that make up the casing can be processed, for example, by punching straight parts, without - in contrast to conventional casings - requiring an expensive and time-consuming (folding) or (folding) of the parts.

The fact that the need for There is no need to (re) fold or (re) fold in the manufacture of the casing according to the present invention, not only in the manufacture of enormous cost savings; on the contrary, the elimination of the generally bulky and hindering folded or folded edges can also result in considerable material savings and significant volume savings, which has a positive effect on, for example, stacked storage and storage of the covers according to the present invention.

But the casings according to the present invention represent an enormous technical advance not only in production, storage and storage; The processing and processing of the sleeves, for example when the information carrier m is mechanically donated, is also favored and accelerated not least due to the complete absence of folded or folded edges, since the sleeve can no longer become problematic due to the lack of bulky or protruding areas or hook or tilt the dispenser.

In this context, it should not be overlooked that in such an unpredictable way when using plastic materials for the film and for the nonwoven also important parameters, such as the surface structure (for example in relation to an embossed film) or the sliding value (for example for the packaging device) ), are adjustable, which is not possible when using (strong) paper, cardboard or cardboard. In particular, the sliding value that can be set for plastic materials has Insofar as it is essential to the invention, since a high sliding value and associated low coefficient of friction decisively reduces the mechanical stress on the flat information carrier when it is removed from the sleeve and when it is inserted into the sleeve.

The use of the plastic film on the outside of the cover and the plastic fleece on at least parts of the inside of the cover also proves to be particularly good insofar as these materials - for example in contrast to fabric - are recyclable, thereby taking the environmental protection concept into account in an exemplary manner , In connection with this, it should not be overlooked that the above-described design of the casing makes it possible to save material anyway.

Furthermore, the use of the plastic film on the outside of the cover and the plastic fleece on at least parts of the inside of the cover also enables mechanical, that is to say automated and thus accelerated, dispensing of the flat, in particular disc-shaped, information carrier m the cover according to the present invention. It must be taken into account here that the flat, in particular disc-shaped, information carrier is transported, so to speak, floating on an air cushion and dispensed into the envelope, whereby this "air cushion transport" is not least due to the necessity of the as yet undescribed and consequently particularly sensitive information carriers on their surfaces in front Protect damage and / or contamination of any kind.

In this context, the person skilled in the art will appreciate in particular that the use of the plastic film on the outside of the cover and the plastic fleece on at least parts of the inside of the cover allows the side walls of the cover to be pulled apart under vacuum, be it by small cups, who attack on the plastic outer side of the shell and suck onto it. In this way, the sleeve can be filled, for example, with a compact disc blank (CD blank) or, for example, with a digital versatile disc blank (DVD blank), which is the case with conventional sleeves made of (strong) paper, cardboard or cardboard is not easily possible.

In this context, it has been found to be particularly useful that, according to the teaching of the present invention, the plastic film and the plastic fleece lie flat against one another and that, according to the teaching of the present invention, the plastic film and the plastic fleece lie at least point by point, at least linearly and / or at least areally with one another are connected so that when the information carrier is automatically dispensed, a recess is formed through the two side walls of the casing, and the information carrier can be inserted securely and without damage.

In contrast to conventional envelopes made of paper or paper-like materials, their Strength and rigidity can only be defined by the thickness of the paper or paper-like materials, the rigidity of the casing according to the teaching of the present invention is possible through an appropriate choice of the plastics used:

Depending on the desired strength and rigidity, the materials polyethylene (PE) and / or polypropylene (PP) and / or polystyrene (PS) are considered for the plastic film; For essentially the same reasons, the plastic fleece can be made of polyethylene (PE) and / or polypropylene (PP) and / or polystyrene (PS). As a result, it can be stated in the result that, in contrast to conventional systems made of (strong) paper, cardboard or cardboard, the present invention can easily achieve mass savings by suitable choice of material.

With regard to the selection of a suitable plastic nonwoven, for example spunbond and / or polyethylene nonwoven or MB nonwoven (= melt-blown nonwoven) and / or polypropylene nonwoven or TB nonwoven (= thermo-bonded nonwoven) are preferred, the latter type of nonwoven thereon is based on being heat-bonded, and is also referred to as (wool) combed fleece (= so-called "carded" fleece). The above-mentioned plastic fleeces are characterized by their material properties being very resistant. One difference between two of the aforementioned types of nonwoven is that nonwoven can be easily colored, whereas polypropylene nonwoven is not accessible for coloring. Another advantage of the present invention, which is not obvious to the person skilled in the art, is that, in comparison to conventional sleeves with a smooth coating on the inside, by arranging the plastic fleece on at least parts of the inside of the sleeve, the number of points of contact between the information carrier and the inside of the shell is significantly reduced; This also - at least in connection with the avoidance of fiber and paper flight through the use of plastic fleece - significantly reduces, even minimizes, the risk of scratches or scoring, i.e. external damage to the sensitive surfaces of the information carrier.

From DE 195 10 701 AI and from DE 295 04 980 Ul a case for receiving at least one disk-shaped information carrier, in particular a compact disc, with at least one pocket made of plastic film and closable by a flap is known, the one with information provided side of the information carrier facing inside is covered by a protective or protective film; However, in this known case the protective or protective film is formed by a translucent nonwoven material film, so that, for example, when using paper nonwoven material, the risk of fiber and paper flying and consequently the risk of scratches or marks, that is, external damage to the sensitive surfaces of the information carrier. Furthermore, in the case familiar from DE 195 10 701 AI and from DE 295 04 980 Ul, it proves disadvantageous that the nonwoven material should be chosen so thin and / or so weak that it is translucent in order to recognize to enable additional information attached to the non-woven material film side of the information carrier by users of the cover. With such a thin and / or weak design of the nonwoven material film, however, there is a not unfounded risk that this nonwoven material film will fray, fray, be damaged or even tear, particularly if the cover is used several times, not least as a result of the sharp edges of the information carrier.

For the reasons mentioned above, the casing known from DE 195 10 701 AI and from DE 295 04 980 Ul cannot provide any useful suggestions for achieving the object of the present invention. Rather, the risk of fiber and paper flying and consequently the risk of scratches or scoring, that is to say of external damage to the sensitive surfaces of the information carrier, is reduced particularly efficiently if, according to a particularly inventive development, the cover has two outer sides and two inner sides, wherein both inner sides are at least partially, in particular over the entire surface, provided with the plastic fleece. This has the advantage that the disk-shaped information carrier can be inserted into the sleeve according to the present invention regardless of the orientation of its surfaces, without fear of damaging the sensitive surface (s) of the information carrier would .

In an alternative, likewise preferred embodiment of the present invention, the shell has two outer sides and two inner sides, one inner side being free of plastic fleece and the other inner side being provided with the plastic fleece at least partially, in particular over the entire surface. In this embodiment, the inside of the sleeve is therefore only provided with the plastic fleece on one side, the information carrier, in particular the Compac disc disc or the (re) writable compact disc (CD) or digital versatile disc (DVD), so It is to be inserted into the envelope that the information carrier can be written on with its surface which can be written by a drive (so-called CD-RW drive = compact disc recordable write drive or so-called DVD-RW drive = digital versatile disc recordable write run) rests on the plastic fleece.

On the other hand, it is not necessary in this connection that the surface of the information carrier, which is not (re) writable, but is printed, for example, with manufacturer information or the like, rests on a plastic fleece; Rather, the side of the sleeve assigned to this non-(re) writable surface of the information carrier can be formed from, for example, (highly) transparent plastic film, which on the one hand enables an unobstructed view of the contents of the sleeve and on the other hand realizes considerable material savings. The use of a (highly) transparent plastic film has the further advantage compared to conventional, for example circular, "windows" that hooking or snagging of the information carrier is reliably prevented when dispensing or when packing, because the plastic film has none Corners, donkey ears or edges on which the information carrier could get stuck (with conventional "windows" the formation of such corners, donkey ears or edges can hardly be avoided, which regularly leads to considerable disruption of the operational processes during the donation of the information carrier).

The advantages of the present invention set out above can be achieved in a particularly satisfactory manner if the thickness of the plastic film is of the order of between approximately 20 micrometers and approximately 350 micrometers. Alternatively or in addition to this, the areal density of the plastic fleece m can be in the order of magnitude between about 5-10 ³ kg / m ² and about 30'10 ^"3 kg / m ² .

If the present invention is to be developed in a particularly inventive manner, the area of the envelope which can be assigned to the (re) writable or described surface of the information carrier and the area which can be assigned to the (non) rewritable surface of the information carrier can have different thicknesses. This feature can be of essential importance in so far as the two surfaces from which the envelope is formed can be processed independently of one another, even with different thicknesses, so that not least the process aimed at the production of the casing is favored.

Different thicknesses of the surfaces forming the casing can be of decisive advantage not only in the manufacture of the casing, but also in the filling of the casing. In particular in the case of mechanical, that is to say automated and thus accelerated, dispensing of the flat, in particular disk-shaped information carrier, the envelope according to the present invention can prove to be expedient if the surface of the envelope can be assigned to the (re) writable or described surface of the information carrier , has a greater thickness than the surface of the cover, which can be assigned to the (non) rewritable surface of the information carrier, because this gives the former surface of the cover a greater stability, that is to say that of

(Re) writable or described area of the information carrier assignable area of the shell is less deformable than that of the not

(Re) writable surface of the information carrier assignable surface of the envelope.

According to a preferred development of the present invention, this is at least partially opaque. In other words, this means that the shell can be neither translucent nor transparent, but rather opaque, so that in the present invention, unlike in DE 195 10 701 AI or differently than in DE 295 04 980 Ul, there is no need for that Plastic fleece so thin or so weak that it is necessarily translucent or transparent is.

If the envelope m is to be further developed in a particularly inventive manner, it is recommended that at least the area of the envelope or the surface of the envelope which can be assigned to the (re) writable or described surface of the information carrier be made opaque. Such a configuration leaves the possibility of the areas of the shell or the surface of the shell that the

(Re) writable surface of the information carrier can be assigned, at least partially designed to be transparent, so as to make it possible to recognize information that is readable with the eyes and that is not on the

(Re) writable surface of the information carrier or on a sheet, booklet, booklet, booklet or the like added to the information carrier and insertable into the sleeve.

Depending on the respective area of application and intended use of the present invention, it may prove expedient if the plastic film on its surface facing the outside and / or on its surface facing the inside or if the plastic fleece is at least partially transparent and / or at least partially colored. While the former measure, as already explained above, guarantees an almost unobstructed view of the information carrier, the latter measure serves, for example, for the aesthetic design of the cover. Alternatively or in addition to this, the plastic film can be at least partially printed on its surface facing the outside and / or on its surface facing the inside or the plastic fleece, preferably at least partially printed with color, and / or at least partially coated, preferably at least partially with color coated, and / or at least partially labeled, for example to increase the degree of opacity close to or up to a maximum value of 97 percent and / or to provide the envelope with usage information, manufacturer information or the like related to its content.

The color can be based on titanium dioxide (T1O2), for example, and regardless of this or in connection with it, the printed area of the cover or the printed surface of the cover can be used, for example, in letterpress printing, flexographic printing, reverse printing, offset printing, screen printing and / or be printed in rotogravure.

According to a more specific, expedient embodiment, the plastic film or the plastic fleece can be at least partially colored white and / or at least partially printed with white color and / or at least partially coated with white color, so that the manufacturer of the information carrier can then use almost all of the design options for the cover are left.

An expedient embodiment in which the Plastic film on its surface facing the inside and / or on which the plastic fleece on its surface facing the inside is at least partially printed, preferably at least partially printed with color, and / or at least partially coated, preferably at least partially coated with color, and / or at least partially is labeled, is also referred to as so-called "reverse printing" and gives the manufacturer and / or in particular the user of the information carrier the opportunity to individually print (again) several times (again) or to label several times (again), for example with a water-soluble one Pen. This is particularly advantageous in the case of (re) writable compact discs (CDs) or (re) writable digital versatile discs (DVDs), in which the information stored can be changed by repeated writing, which results in the necessity of having the sleeve on them Label on the outside or on the outside (again).

According to a particularly advantageous development of the present invention, the areas of the casing or the surface of the casing that are not digital, for example, by a drive (so-called CD-RW drive = compact disc recordable write drive or so-called DVD-RW drive) Versatile disc recordable write runs (re) writable surface of the information carrier are assignable, transparent, whereas the area of the envelope or the surface of the envelope that can be assigned to the (re) writable or described surface of the information carrier, dyed and / or printed with color and / or coated with color is.

In a particularly expedient manner, the plastic film and / or the plastic fleece can be at least partially embossed. The type of embossing and the intensity of the embossing are of essential importance to the invention in that, for example, a coarsely structured embossing of the plastic fleece has relatively few points of contact and contact between the flat information carrier and the inside of the sleeve and therefore a good sliding value, that is to say requires a low coefficient of friction; but also eme fern structured embossing of the plastic film or the plastic fleece can meet all requirements in this regard to the sliding value and the coefficient of friction.

According to a preferred embodiment of the present invention, the plastic film is at least partially foamed. This measure enables an additional protective effect in the sense of cushioning and / or insulation of the flat, in particular disc-shaped, information carrier which rests in the casing.

According to a particularly inventive further development of the present cover, the plastic film and the plastic fleece are connected to one another over the full area, for example by the plastic fleece being glued and / or welded and / or sealed and / or extrusion-laminated, in particular by means of at least one flat die, to the plastic film. This will, in particular when pulling the information carrier out of the envelope or when inserting the information carrier m the envelope, a distortion or "wave beating" of the plastic fleece on the plastic film prevents m reliable manner.

For essentially the same purposes, at least partially at least one connecting means, for example an adhesion promoter, can optionally be provided, in particular sprayed or extrusion-coated or extrusion-laminated, between the plastic film and the plastic fleece.

As an alternative or in addition to this, at least partially at least one connecting means can be provided on the side of the plastic film facing the information carrier, in particular sprayed or extrusion-coated or extrusion-laminated. This connecting means is particularly important when the edges of the casing are sealed at least point by point, for example by means of at least two sealing jaws acting on the outer sides of the casing, because the connecting means ensures in an advantageous manner that the edges of the casing can be sealed together and that a "straight" Envelope is formed without any distortion or "waving" of the edges of the envelope.

The above-described "straight", that is to say undistorted, design of the casing can advantageously be achieved by extruding at least one outside of the casing, the extruded outside of the casing preferably also on its surface facing the information carrier the connecting means is extrusion-coated or extrusion-laminated or co-extruded.

One example is the extrusion of the plastic film from preferably transparent polypropylene (PP), the connecting means being applied to the still warm, possibly already partially solidified plastic film, and the extruded plastic film together with the connecting means between rollers, in particular embossing rollers, or between rollers, in particular Embossing rollers, is sent through in order to create a permanent bond between the plastic film and the connecting means.

According to a preferred embodiment of the present invention, the connecting means is based on at least one copolymer and / or on polyethylene (PE) and / or on polypropylene (PP) and / or on polystyrene (PS); in particular, the connecting means can be made of easily flowable materials, such as ethylene butyl acrylate (EBA) and / or ethylene methyl acrylate (EMA) and / or

Ethylene vinyl acrylate (EVA) and / or Surlyn.

Advantageously, the melting temperature of the connecting means, which is, for example, in the order of about 120 degrees Celsius, is lower than the melting temperature of the plastic film, which is, for example, in the order of approximately 220 degrees Celsius. This makes it possible, inter alia, for the plastic film to be processed in a still warm state immediately after the extrusion and for the connecting means to be applied, so that this still occurs warm and therefore still partially formable material of the plastic film can form a particularly intimate connection with the connecting means

Furthermore, at least partially at least one adhesive, preferably at least one cold adhesive and / or at least one thermally active adhesive (so-called hot-melt adhesive), can be provided between the plastic film and the plastic fleece, the adhesive according to a particularly preferred embodiment of the present invention between the at least partially printed with color and / or at least partially coated with plastic film and the plastic fleece is at least partially provided. Here, the adhesive can be colored to intensify an opacity effect

In order to prevent the information carrier from accidentally falling out of the envelope, for example when the envelope is being transported, at least in sections at least one closure is arranged along the opening in accordance with an expedient development of the present invention and is practically resealable so that it is flat and in this case preferably disk-shaped information carrier can be removed several times from the casing and inserted back into it.

Advantageously, the closure - like the rest of the material of the casing - is made of plastic, for example in the form of a so-called M ni grip system, in which the closure has at least one band on one surface of the casing and on the one other surface of the sleeve has at least one groove-shaped receptacle for the band assigned to the band. Alternatively or in addition to this, the closure can optionally also be designed as at least one adhesive label and / or as at least one adhesive flap.

According to an expedient development of the present invention, the closure is hook-and-loop, that is to say designed as a hook-and-loop fastener, which promotes the reclosability of the cover in that a hook-and-loop fastener can often be opened and closed again, so that such a closure can also be repeated Stress by removing the disc-shaped information carrier from the envelope and reinserting it into the envelope with subsequent reclosing of the envelope easily

In a particularly clever embodiment of the present invention, the closure on the outside of the cover and / or on the inside of the cover has at least a Velcro-shaped closure band which is assigned to at least one area of the plastic fleece. Here, the present invention adopts the property of the plastic fleece to adhere to the Velcro-shaped fastener tape, so that effective and reliable cohesion between the Velcro-shaped fastener tape and the corresponding area of the plastic fleece is ensured. If the Velcro-shaped fastening tape is attached to the outside of a surface of the cover, then according to a preferred development of the present invention the surface of the cover that can be assigned to the (re) writable or described surface of the information carrier is over the emplacement opening onto the Velcro-shaped one Fastening strap foldable to form the closure in this way.

In this context, the surface of the envelope, which can be assigned to the (re) writable or described surface of the information carrier, can advantageously protrude beyond the other surface of the envelope, at least in the region of the opening, so that the surface of the envelope, which the (again ) writable or described area of the information carrier can be assigned, can be folded over the opening Emsteckof on the Velcro-shaped fastener tape.

But regardless of the formation of a Velcro fastener, it is not without a certain usefulness if the surface of the cover, which can be assigned to the (re) writable or described surface of the information carrier, projects beyond the other surface of the cover, at least in the area of the opening, because this will result in the opening Both the introduction of the disk-shaped information carrier m the sleeve and the removal of the disk-shaped information carrier from the sleeve are facilitated, since the user of the sleeve can intuitively grasp how the sleeve is to be handled by the area of the sleeve which protrudes in the area of the insertion opening; apart from that, the manual handling of the opening by the projecting area much easier, because the user of the cover can easily grasp the opening.

According to an advantageous development of the present invention, the sleeve is at least partially provided with at least one perforation, with at least one embossing and / or with at least one punch. This proves to be particularly useful if the closure is to be accomplished by expediently gluing, sewing, welding and / or sealing the edge of the sleeve associated with the insertion opening, in which case the sleeve in the area of the at least one point glued, sewn, welded and / or sealed edge associated with the insertion opening is at least partially provided with at least one perforation, with at least one embossing and / or with at least one punch.

Practically, the perforation, the embossing and / or the punching now runs essentially parallel to the edge assigned to the emplacement and / or the distance of the perforation, the embossing and / or the punching from the edge assigned to the emplacement is practically on the order of about two Millimeters and about ten millimeters, the closure can be opened and the information carrier can be removed from the cover by separating the edge of the cover assigned to the insertion opening along the perforation, along the embossing and / or along the punching, so that the information carrier is now separated by the released opening unhindered is accessible.

According to a preferred embodiment of the present invention, the casing is at least partially provided with at least one sealing seam and / or with at least one sealing strip, the sealing seam and / or the sealing strip being essentially parallel to the edge assigned to the insertion opening and / or essentially parallel to the others Edges of the envelope run.

The distance of the sealing seam from the edge assigned to the opening and / or from the further edges is expediently on the order of magnitude between about seven millimeters and about thirty millimeters. Regardless of this or in connection with this, the width of the sealing strip m can be of the order of magnitude between approximately seven millimeters and approximately thirty millimeters.

In order to enable em filing the cover, for example in a folder, m a ring binder or m a binder, according to an advantageous embodiment of the present invention, at least two preferably punched round holes and / or elongated holes are provided for filing the cover. If the round holes and / or elongated holes are expediently punched with a punching tool at high temperature, then the melting of the materials, in particular the plastic materials, forms the shell on the edges of the punched holes, that is to say the round punches and / or elongated holes form a kind of bulge , which has a stabilizing and reinforcing effect when the case is filed several times, so that e "tearing out" the round holes and / or elongated holes due to their fixed edge is prevented in a reliable manner.

Optionally, the round holes and / or elongated holes can be post-treated with a stamp-like tool at a high temperature, so that an additional welding and thus strengthening of the filing holes can be accomplished at their breaking points.

The round holes and / or elongated holes can be used to form at least one filing strip between the one assigned to the insertion opening

Edge and the sealing seam or between the other edges and the sealing seam or in the sealing strip.

For example, for reasons of archivability and retrievability of the disk-shaped information carriers or in the course of a proper and clear office organization, according to an expedient development of the present invention, at least one insertion channel for at least one labeling strip can be arranged on the edge of the casing. Such an optional measure can be of essential character to the invention in that an information carrier in the form of a compact disc blank or in the form of a (re) writable compact disc (CD) or digital versatile disc (DVD) naturally cannot be printed or printed on Labeling can be provided with regard to its content, since this content by the user of the compact disc blank or the (re) writable compact disc (CD) or digital versatile disc (DVD) is determined.

In order to guarantee in a reliable manner that the further edges of the cover are closed and consequently the information carrier can only be removed and put back through the insertion opening, the further edges of the cover are, according to a preferred embodiment, glued, sewn, welded and / or sealed at least at points ,

Whether the other edges of the casing are only punctiform or section-by-section or continuous, that is to say glued, sewn, welded and / or sealed to one another, depends, among other things, on the thickness of the materials selected for the casing. If, for example, the materials chosen for the casing, in particular the plastic materials chosen for the casing, are relatively thick, their edges become wavy when they are welded continuously; For this reason, it may be advisable to weld the other edges only selectively, for example in the form of offset stitches, that is to say with interruptions, so that a punctiform seam (or a so-called knurled seam) is produced.

In the case of sewing, the other edges of the sheath can be sewn in a particularly expedient embodiment with at least one plastic thread, in particular made of polyethylene (PE) and / or of polypropylene (PP) and / or of polystyrene (PS).

The bond between the Edges of the sheath also take place by so-called "hot needles", that is to say by piercing the plastic materials with a hot needle. Here, the plastic materials are melted and consequently connected to one another in an effective and stable manner.

Naturally, the envelope according to the present invention essentially corresponds to the size of the information carrier to be stored therein in order to ensure an adequate reception of the information carrier of the envelope. Here, the cover is expediently approximately rectangular, in particular approximately square. As an alternative to this, the edge of the sleeve opposite the insertion opening can be approximately semicircular.

According to a particularly inventive development of the present casing, at least one outside of the casing is extruded, the extruded outside of the casing preferably being extrusion-coated or extrusion-coated with the plastic fleece on its surface facing the information carrier. One example is the extrusion of the plastic film made of polypropylene (PP), whereby a sheet of plastic fleece is applied to the still warm, possibly already partially solidified plastic film and the extruded plastic film together with the plastic fleece between rolls, in particular embossing rolls, or between rolls, in particular Prague rollers, is sent through in order to create a permanent bond between the plastic film and the plastic fleece, even without a connecting means create.

The omission of em connecting means between plastic film and plastic fleece is made possible here, inter alia, by processing the plastic film in a still warm state immediately after the extrusion and applying the plastic fleece so that the material of the plastic film, which is still warm and therefore still partially moldable, is partially processed m can penetrate the pores or the structure of the plastic fleece, thereby creating a particularly intimate connection between the plastic film and the plastic fleece.

The present invention also includes a sleeve provided for storing at least one flat information carrier, in particular at least one compact disc blank or at least one (re) writable compact disc (CD) or digital versatile disc (DVD), whose further edges are closed and which has at least one outside and at least one inside arranged opposite to the outside, wherein the surface of the cover is formed by at least one plastic film and the other surface of the cover is formed by at least one plastic fleece.

Thus, on the surface of the sleeve, the sensitive surface of the information carrier, such as the not yet described side of a compact disc (= a so-called compact disc blank) or the (re) writable side of a compact disc (CD) or digital Versatile Disc (DVD), facing, the plastic film can be dispensed with, in particular if a plastic fleece of appropriate thickness is selected so that the plastic fleece does not fray, fray, be damaged or even tear even with frequent and intensive use of the casing.

The present invention further includes a sleeve provided for storing at least one flat information carrier, in particular at least one compact disc blank or at least one (re) writable compact disc (CD) or digital versatile disc (DVD), whose other edges are closed and which has at least one outer side and at least one inner side arranged opposite the outer side, both surfaces of the casing being formed by at least one plastic fleece.

It is therefore possible to dispense with the plastic film on both surfaces of the casing, in particular if a plastic fleece of appropriate thickness is selected, so that the plastic fleece does not fray, fray, be damaged or even tear even with frequent and intensive use of the casing. This has the advantage that the disc-shaped information carrier can be inserted regardless of the orientation of its surfaces in the sleeve according to the present invention, without fear of damaging the sensitive surface (s) of the information carrier.

The present invention finally includes eme for storing at least one flat Information carrier, in particular at least one compact disc blank or at least one (re) writable compact disc (CD) or digital versatile disc (DVD), provided, eme insertion opening shell, the other edges are closed and the at least one outside and at least one has the inner side arranged opposite to the outer side, the first outer side having at least one plastic film, the second outer side being formed from at least one paper material, such as cardboard, (strong) paper or cardboard, the inner side assigned to the second outer side being at least partially is provided with at least one plastic fleece, the paper material and the plastic fleece lie flat against one another and the paper material and the plastic fleece are connected to one another at least point by point, at least in the form of an inlay and / or at least in areas

Thus, on the surface of the sleeve, the sensitive surface of the information carrier, such as the side of a compact disc (= a so-called compact disc blank) that has not yet been described, or the (re) writable side of a compact disc (CD) or digital Versatile disc (DVD) facing, the plastic film can be dispensed with, because the paper material and the plastic fleece lie flat against one another and are at least point-wise, at least lm-shaped and / or at least partially flat with one another connected.

Polyethylene (PE) and / or polypropylene (PP), in this case preferably (highly) transparent polypropylene (PP), and / or polystyrene (PS), are used for the choice of the material of the plastic film, with polyethylene (PE) in particular offering the advantage that it connects at least point-wise gluing, sewing, welding and / or sealing the other edges of the casing with the plastic fleece under heating or heating m in an optimal manner and thus offers a solid cohesion that opens or tears the other edges the shell almost impossible.

According to an expedient embodiment of the present invention, the first outer side has a plastic film made of a first material, preferably made of polypropylene (PP), in this case in particular made of (highly) transparent polypropylene (PP), and the inner side assigned a plastic film made of a second material , preferably made of polyethylene (PE). Here, too, polyethylene (PE) has the advantage that it bonds optimally with the plastic fleece when heated or heated when at least point-by-point gluing, sewing, welding and / or sealing the other edges of the casing and thus offers a firm cohesion , which makes opening or tearing the other edges of the shell almost impossible.

According to a particularly inventive development of the present casing, the paper material and the plastic fleece are at least partially at least linearly and / or at least partially connected to one another in a flat manner, for example by gluing and / or welding and / or sealing the plastic fleece onto the paper material. This prevents, especially when pulling out the information carrier from the sleeve or when inserting the information carrier m, the sleeve, e distortion or "wave" of the plastic fleece on the paper material m reliable manner.

For essentially the same purposes, at least partially at least one connection means, for example an adhesion promoter, can optionally be provided between the paper material and the plastic nonwoven, in particular sprayed or extrusion-coated or extrusion-laminated.

As an alternative or in addition to this, on the side of the paper material facing the information carrier at least partially at least one connecting means can be provided, in particular (em) sprayed or extrusion-coated or extrusion-laminated. This connecting means is particularly important when connecting the edges of the casing at least point by point, for example by means of at least two pressing jaws acting on the outer sides of the casing, because the connecting means ensures in an excellent manner that the edges of the casing can be glued to one another and that a "straight" Envelope is formed without any distortion or "waving" of the edges of the envelope. According to a preferred embodiment of the present invention, the connecting means is based on at least one copolymer and / or on polyethylene (PE) and / or on polypropylene (PP) and / or on polystyrene (PS); in particular, the connecting means can be made of easily flowable materials, such as ethylene butyl acrylate (EBA) and / or ethylene methyl acrylate (EMA) and / or

Ethylene vinyl acrylate (EVA) and / or Surlyn.

Furthermore, at least partially at least one adhesive, preferably at least one cold adhesive and / or at least one thermally active adhesive (so-called Ho-melt adhesive) can be provided between the paper material and the plastic fleece.

In a particularly expedient manner, the plastic fleece can be at least partially embossed. In this context, the type of embossing and the intensity of the embossing are of significance for the invention, since, for example, a roughly structured embossing of the plastic fleece has relatively few points of contact and contact of the flat information carrier with the inside of the sleeve and therefore a good sliding value, that is to say one low coefficient of friction; but even a finely structured embossing of the plastic fleece can meet all requirements regarding the sliding value and the coefficient of friction.

Further refinements, features and advantages of the present invention are described below with reference to the Figures 1 to 13 described by ten exemplary embodiments of the case are illustrated in the exemplary form.

Identical reference numerals refer to elements or features of the same or similar design in FIGS. 1 to 13.

Figure 1 shows a first embodiment of a case according to the present invention, in a side view. The case serves to store a compact disc blank (CD-Rohlmgs (not shown in FIGS. 1 to 11 for reasons of clarity)) and has an insertion opening 40 for this purpose, the further edges 42, 44, 46 of the case being closed are. The sleeve is formed from a two-layer composite material and has outer sides 15, 17 and inner sides 35, 37 arranged opposite to the outer sides 15, 17 (cf. also FIG. 2, the sectional view of the first exemplary embodiment of the sleeve along the section line II - II shown in Figure 1). As can be seen from FIGS. 1 and 2, the shell has on its outer sides 15, 17 a plastic film 10; Furthermore, the inside of the cover 35, 37 is provided with a plastic fleece 30, the plastic film 10 and the plastic fleece 30 abutting one another over the entire surface and the plastic film 10 and the plastic fleece 30 being connected to one another over the entire surface.

This prevents, particularly when the information carrier is pulled out of the envelope or when the information carrier m is pushed in, the distortion or "wave beating" of the plastic fleece 30 on the plastic film 10. To support this, the area between the plastic film 10 and the plastic fleece 30 is provided with a connecting means 20 in the form of an adhesion promoter (cf. FIG. 2).

While in the first exemplary embodiment of the cover illustrated with reference to FIGS. 1 and 2, both inner sides 35, 37 are provided with the entire surface of the plastic fleece 30, in the second exemplary embodiment of the cover shown in FIGS. 3 and 4 the inner side 35 is free of plastic fleece, whereas the other inner side 37 all over with the plastic fleece 30 is provided (cf. FIG. 4, which shows a sectional view of the second exemplary embodiment of the casing along the section line IV-IV from FIG. 3).

In this second exemplary embodiment, the inside of the envelope is therefore provided with the plastic fleece 30 on only one side 37, the information carrier being inserted into the envelope so that the (again) writable surface of the information carrier rests on the plastic fleece 30. On the other hand, it is not necessary in this connection that the surface of the information carrier, which cannot be (re) written, rests on a plastic fleece; rather, the side 35 of the sleeve, which is (not) rewritable surface of the information carrier, is formed from highly transparent plastic film 10, which on the one hand enables an unobstructed view of the contents of the sleeve and on the other hand realizes considerable material savings.

As can also be seen in FIG. 4, a connection means 20, especially an adhesion promoter, is provided between the plastic film 10 and the plastic fleece 30. In addition to this, a connection means 20 'is also provided on the side 35 of the plastic film 10 facing the information carrier.

This connecting means 20 'is important when sealing the edges 42, 44, 46 (see FIG. 3) of the casing by means of two sealing jaws acting on the outer sides 15, 17 of the casing, because the connecting means 20' ensures that the edges 42, 44 , 46 of the shell are sealed together and that a "straight" shell is formed without any distortion or "wave" of the edges 42, 44, 46 of the shell (see FIGS. 3 and 4).

The above-described "straight", that is to say undistorted configuration of the casing according to the second exemplary embodiment of FIGS. 3 and 4 can be achieved in that the outer sides 15, 17 of the casing are extruded, the extruded outer sides 15 and 17 of the casing respectively on their surfaces facing the information carrier are extrusion-coated with the connecting means 20 'or 20. With regard to the second exemplary embodiment according to FIGS. 3 and 4, an extrusion of the plastic film 10 from highly transparent polypropylene (PP) is to be carried out, the connecting means 20 ', 20 being applied to the still warm, possibly partially already solidified plastic film 10 and extruding it Plastic film 10 is sent together with the connecting means 20 ', 20 between embossing rollers in order to create a permanent bond between the plastic film 10 and the connecting means 20', 20.

The connecting means 20 ', 20 is based on a copolymer, the melting temperature Ty of the connecting means 20', 20 being of the order of magnitude of approximately 120 degrees Celsius and therefore considerably lower than the melting temperature TK of the plastic film 10, which is of the order of approximately 220 Degrees Celsius moves. This makes it possible, inter alia, for the plastic film 10 to be processed immediately after the extrusion in the still warm state and for the connecting means 20 ', 20 to be applied, so that this is still warm and therefore partially still formable material of the plastic film 10 can enter into a particularly intimate connection with the connecting means 20 ', 20.

FIG. 5 shows a sectional view of a third exemplary embodiment of a casing according to the present invention.

This third exemplary embodiment is partially opaque in that the upper half of the shell in FIG. 5 is neither translucent nor transparent, but rather opaque, so that there is no need to make the plastic fleece 30 particularly thin or particularly weak

In particular, in the third exemplary embodiment illustrated in FIG. 5, the upper region of the envelope, which can be assigned to the (re) writable or described surface of the information carrier, is opaque. This configuration leaves the possibility of transparently designing the lower region of the envelope in FIG. 5, which can be assigned to the non-(re) writable surface of the information carrier, in order to make it possible to recognize information that can be read by the eyes and that is not (re) writable on the surface Surface of the information carrier or on a sheet, booklet, booklet, booklet or the like which is inserted into the information carrier and which is insertable, is to be ensured.

With reference to FIG. 5, the upper half of the casing according to the third exemplary embodiment, it can be seen that the plastic film 10 has on its surface facing the inside 37 of the casing Color Form of a layer of color 70 is printed in order to maximize the degree of opacity and still leave the manufacturer of the information carrier with almost all design options for the cover.

Furthermore, adhesive in the form of an adhesive layer 20 is provided between the plastic film 10 printed with ink 70 and the plastic fleece 30, so that the ink layer 70 on its upper surface 5 from the plastic film 10 and at its lower surface m 5 of the adhesive layer 20 is limited and therefore effectively included. At the same time, the adhesive 20 ensures that the plastic film 10 with the color layer 70 and the plastic fleece 30 lie against one another over the entire surface and are connected to one another over the entire surface.

As a result, with reference to the third exemplary embodiment of the present case shown in FIG. 5, it should be noted that the lower surface of the case in FIG. 5 is that which is not the drive (so-called CD-RW drive = compact disc recordable write drive or So-called DVD-RW drive = Digital Versatile Disc-Recordable Write-Run) (re) writable surface of the information carrier can be assigned, is transparent, whereas the upper surface of the casing, which corresponds to the (re) writable or described surface of the Information carrier is assignable, coated with opaque color 70 and is therefore opaque.

FIG. 6 shows a sectional view of a fourth exemplary embodiment of a casing according to the present invention. This fourth exemplary embodiment shows an envelope provided for storing a flat information carrier, which has outer sides 15, 17 and inner sides 35, 37 arranged opposite to outer sides 15, 17.

The lower surface of the cover in FIG. 6 is formed by a plastic film 10, whereas the upper surface of the cover in FIG. 6 is formed by a plastic fleece 30. Thus, on the upper surface of the casing, which is the sensitive surface of the information carrier, such as the side of a compact disc (= a so-called compact disc blank) that has not yet been described or the (re) writable side of a compact disc ( CD) or Digital Versatile Disc (DVD) facing, the plastic film can be dispensed with, in particular because plastic fleece 30 of appropriate thickness is provided, so that the plastic fleece 30 also with frequent and intensive use of the casing according to the fourth exemplary embodiment of the present invention does not fray, fray, be damaged or even tear.

FIG. 7 shows a sectional view of a fifth exemplary embodiment of a casing according to the present invention.

This fifth exemplary embodiment shows an envelope provided for storing a flat information carrier, the outer sides 15, 17 and inner sides 35, 37 arranged opposite to the outer sides 15, 17 having .

In Figure 7, both surfaces of the shell are formed by a plastic fleece 30, so that the plastic film can be dispensed with on both surfaces of the shell, in particular because a plastic fleece 30 of appropriate thickness is provided, so that the plastic fleece 30 is also used frequently and intensively the case according to the fifth embodiment of the present invention does not fray, fray, be damaged or even tear.

This has the advantage that the disk-shaped information carrier can be inserted regardless of the orientation of its surfaces in the shell according to the fifth exemplary embodiment in FIG. 7, without fear of damaging the sensitive surface (s) of the information carrier.

FIG. 8 shows a sectional view of a sixth exemplary embodiment of a casing according to the present invention.

The sixth exemplary embodiment is an envelope provided for storing a flat information carrier, which has two outer sides 15, 17 and two inner sides 35, 37 arranged opposite to the respective outer side 15, 17. Here, the first outer side 15 has a plastic film 10, whereas the second outer side 17 is made of paper material. The inside 37 assigned to the second outside 17 is provided with a Provided plastic fleece 30, wherein the paper material and the plastic fleece 30 lie flat against one another and the paper material and the plastic fleece 30 are connected to one another over the entire surface by the plastic fleece 30 being glued to the paper material by means of an adhesive layer 20. In this way, especially when pulling out the information carrier from the sleeve or when inserting the information carrier, the sleeve, em distortion or "waves" of the plastic fleece 30 on the paper material is prevented.

As a result, the plastic film is dispensed with on the surface of the envelope shown in the upper half of FIG. 8, which faces the sensitive surface of the information carrier.

Polyethylene (PE) is selected for the material of the plastic film 10 shown in the lower half of FIG. 8, which offers the advantage that the additional edges 42, 44, 46 of the casing are welded to the m of the upper half of FIG To connect plastic fleece 30 with heating in an optimal manner and thus to offer a firm cohesion which makes em opening or tearing of the further edges 42, 44, 46 of the casing almost impossible.

As can be seen from the graphic representation of the sixth exemplary embodiment according to FIG. 8, the surface of the envelope which can be assigned to the (re) writable or described surface of the information carrier and which is shown in the upper half of FIG. 8 and that of the non-(re) writable surface of the information carrier assignable, m shown in the lower half of Figure 8 different thicknesses. This feature is essential insofar as the two surfaces from which the casing is formed can be processed independently of one another, even with different thicknesses (cf. FIG. 8), which not least favors the process aimed at producing the casing.

Different thicknesses of the surfaces forming the casing are of decisive advantage not only in the manufacture of the casing, but also in the filling of the casing. In particular in the case of mechanical, that is to say automated and thus accelerated, dispensing of the flat information carrier into the envelope according to FIG. 8, it proves to be expedient if the surface of the envelope shown in the upper half of FIG. 8 is that of the (re) writable or described surface of the information carrier has a greater thickness than the area of the envelope shown in the lower half of FIG. 8, which can be assigned to the non-(re) writable area of the information carrier, because this gives the former area of the envelope greater stability, that is to say the the

Instead of the plastic film 10 made of polyethylene (PE), the sixth exemplary embodiment according to FIG. 8 also have a plastic film composite 10, which is constructed as follows:

The first outside 15 has a plastic film made from a first material, namely highly transparent polypropylene (PP), and the inside 35 assigned to the first outside 15 has a plastic film made from a second material, namely polyethylene (PE). Here, too, the polyethylene (PE) again has the advantage that when the other edges 42, 44, 46 of the sheath are welded point by point, it is optimally connected to the plastic fleece 30 with heating and thus offers a solid cohesion that opens or opens Tear the other edges 42, 44, 46 of the shell almost impossible.

Although this is not readily apparent from FIG. 8 for technical reasons, the plastic fleece 30 is embossed in the sixth exemplary embodiment of the present invention. The type of embossing and the intensity of the embossing are of considerable importance in this connection, in that the roughly structured embossing of the plastic fleece 30 selected in the sixth exemplary embodiment according to FIG. 8 has relatively few points of contact and contact of the flat information carrier with the inside 37 of the casing and hence a good sliding value, that is, a low coefficient of friction.

As can further be seen from FIG. 8, in the sixth exemplary embodiment of the present casing, the plastic film 10 is on the inside 35 thereof facing area in sections with information

25 labeled. This is also called a so-called

"Konterdruck" 25 denotes and opens the

Manufacturers and the user of the information carrier have the option of individually re-labeling the outside 15 of the casing several times with a water-soluble pen, which is particularly the case with

(re) writable compact discs (CDs) or at

(Re) writable digital versatile discs (DVDs) is advantageous, in which the stored

Information can be changed by storing data several times, which results in the need to have the casing on its outside 15

to label (again).

FIG. 9 shows a sectional side view of a seventh exemplary embodiment of a casing according to the present invention.

The seventh exemplary embodiment according to FIG. 9 is characterized in that the plastic film 10 extrudes the casing and is extrusion-laminated with plastic fleece 30 on its surface facing the information carrier. In this case, the plastic film 10 is extruded from polypropylene (PP), a sheet of plastic fleece 30 being applied to the still warm, possibly partially already solidified plastic film 10 and the extruded plastic film 10 being sent together with the plastic fleece 30 between embossing rollers, also without Lanyard between plastic film 10 and plastic fleece 30 to create a permanent bond. The waiver of e connecting means between plastic film 10 and plastic fleece 30 is made possible here, inter alia, by processing the plastic film 10 immediately after extrusion while it is still warm and applying the plastic fleece 30 so that the material, which is still warm and therefore still partially moldable Plastic film 10 can partially penetrate the pores or into the structure of the plastic fleece 30, thereby creating a particularly intimate connection between the plastic film 10 and the plastic fleece 30

The seventh exemplary embodiment of the present invention, illustrated with reference to FIG. 9, furthermore has a closure 60, which is designed like a Velcro fastener, that is to say as a Velcro fastener, which promotes the reclosability of the casing in that the Velcro fastener can often be opened and closed again, so that em such a closure 60 also a repeated stress by removing the disc-shaped information carrier from the envelope and reinserting the envelope with subsequent reclosing the envelope easily.

For this purpose, the closure 60 on the outside 15 of the cover has a Velcro-shaped closure band 65, which is assigned to the upper left area of the plastic fleece 30 in FIG. Here, the seventh exemplary embodiment according to FIG. 9 has the property of the plastic fleece 30 to adhere to the Velcro-shaped fastening tape 65, so that effective and reliable cohesion between the Velcro-shaped fastener tape 65 and the corresponding area of the plastic fleece 30 arranged at the top left in FIG. 9 is ensured.

Since, in the seventh exemplary embodiment in FIG. 9, the Velcro fastener tape 65 is attached to the outside 15 of a surface of the cover, the left surface of the cover in FIG. 9, which can be assigned to the (again) writable or described surface of the information carrier, is via the insertion opening 40 can be folded away according to the arrow P onto the Velcro-shaped fastener tape 65 in order to form the fastener 60 in this way.

It can be seen from FIG. 9 that the left surface of the casing in FIG

(Re) writable or described surface of the information carrier can be assigned, which projects over the right-hand surface of the casing in the region of the insertion opening 40 in FIG. 9, so that the left-hand surface of the casing in FIG

(Re) writable or described surface of the information carrier is assignable, can be folded over the insertion opening 40 according to the arrow P onto the Velcro-shaped fastening tape 65

However, regardless of the formation of the Velcro fastener, in the seventh exemplary embodiment according to FIG. 9 there is no certain expediency if FIG. 9 left surface of the cover, which can be assigned to the (re) writable or described surface of the information carrier, the right surface in FIG. 9 the shell in Exceeds the area of the insertion opening 40, because this facilitates both the insertion of the disk-shaped information carrier m the sleeve and the removal of the disk-shaped information carrier from the sleeve, since the user can intuitively grasp the sleeve through the area of the sleeve which projects in the area of the insertion opening 40 can, how to handle the case; apart from this, the manual handling of the insertion opening 40 is made considerably easier by the protruding area, because the user of the cover can easily grip the insertion opening 40.

While the first exemplary embodiment of the cover illustrated with reference to FIGS. 1 and 2 and the second exemplary embodiment of the cover illustrated with reference to FIGS. 3 and 4 are approximately square in plan m (see FIGS. 1 and 3) in order to adequately accommodate the information carrier m to ensure the envelope, in the eighth exemplary embodiment shown in FIGS. 10 and 11, the edge 48 of the envelope m opposite the insertion opening 40 is approximately semicircular in order to ensure adaptation to the shape of, for example, a circular information carrier.

In order to prevent the information carrier from accidentally falling out of the envelope, for example when the envelope is being transported, a closure 60 (see FIG. 10) made of plastic is arranged along the insertion opening 40 in FIGS. 10 and 11, which is designed to be resealable so that the disc-shaped information carrier can be removed from the casing several times and then inserted again.

As can be seen in FIG. 11 (= sectional view of the eighth exemplary embodiment of the casing along the section line XI-XI from FIG. 10), the closure 60 m is designed in the form of a so-called Mmi-Grip system, that is to say the closure 60 points at m The upper end of the left-hand surface of the band 610 in FIG. 11 and the groove-shaped receptacle 620 for the band 610 assigned to the band 610 at the upper end of the right-hand surface of the FIG. 11 band.

FIG. 12 shows a ninth exemplary embodiment of a casing according to the present invention, with a view from above.

Here, the shell is provided with a perforation 50. This proves to be useful in that the closure is accomplished by welding the edge of the sleeve associated with the insertion opening 40. By providing the casing in the region of the welded edge associated with the insertion opening 40 with the perforation 50, the perforation 50 running essentially parallel to the edge associated with the insertion opening 40, the closure can be opened and the information carrier of the casing can be removed by removing the Edge 40 of the cover assigned to the insertion opening is severed along the perforation 50, so that the information carrier is freely accessible through the now opened insertion opening 40.

To reliably guarantee m that the other edges 42, 44, 46 of the envelope are closed and consequently the information carrier can only be removed (and put back) through the insertion opening 40, the further edges 42, 44, 46 of the casing are only punctiform, that is to say welded in the form of offset stitches with interruptions between the punctures, so that m FIG. 12 a punctiform seam (or a so-called edge seam) can be seen.

The deeper background of this only selective connection of the two surfaces constituting the envelope can be seen in the fact that the plastic materials chosen for the envelope according to FIG. 12 are relatively thick, so that these plastic materials would become wavy at their edges 42, 44, 46 if they were welded continuously ,

FIG. 13 finally shows a tenth exemplary embodiment of a casing according to the present invention, top view.

The casing according to the tenth exemplary embodiment is provided near its left edge in FIG. 13 with a sealing seam 80 which runs essentially parallel to the edge 42 of the casing. The distance of the sealing seam 80 from the edge 42 is chosen so that e filing of the case is made possible for a folder, a ring binder or a folder, insofar as two punched round holes 85 are provided for filing the case.

Here, the circular holes 85 are punched with a high-temperature punch, so that by melting the plastic materials of the casing on the edges of the punch holes, that is to say Round holes 85 a type of bead is formed, which has a stabilizing and reinforcing effect when the sleeve is filed several times, so that em "tearing out" of the round holes 85 is prevented as a result of their fixed edge. The two round holes 85, which are arranged in the tenth embodiment of FIG. 13 to form a filing strip between the edge 42 and the sealing seam 80, are additionally treated with a stamp-like tool at a high temperature, so to a certain extent additional welding and thus strengthening of the filing holes on them Breaking points is accomplished.

For reasons of archivability and re-usability of the disk-shaped information carriers and in the course of a proper and clear office organization, on the right edge 46 of the tenth exemplary embodiment of the present case there is an insertion channel 90 for one (m FIG. 13 not shown for reasons of clarity) Arrange labeling strips.

This measure is important insofar as an information carrier in the form of a compact disc blank or in the form of a (re) writable compact disc (CD) or digital versatile disc (DVD) naturally does not have an imprint or a label with regard to its content may be, since this content is determined by the user of the compact disc blank or the (re) writable compact disc (CD) or digital versatile disc (DVD).
