Description

"Disposable Package and Apparatus for Forming Same The Invention relates to a disposable package and an apparatus for forming the same and to a Apparatus for filling the disposable package with liquid It is known to employ a Strip or a web of packaging material by means of a longitudinal seam to form a tube to shape and almost simultaneously to fill this tube with liquid, whereby the hose preferably runs vertically, and then a series of transverse ones To attach seams or seals at certain intervals and in this way the Separate hose or pipe in the area of these seams or seals so that several packs are created, each of which contains liquid. It is also possible, to provide further seams or seals, so that a number of pillows or Tablet-shaped packs are produced. But it can also be adjacent Seams or seals are formed in planes at right angles to each other, so that they form a series of tetrahedral packs, the packaging material can Paper or paper-like material, with or without a coating or a layer of thermoplastic material on at least one of the surfaces, which is when the tape or strip is formed into a tube or tube is, the inside of which forms. The strip of packaging material can also be used entirely consist of thermoplastic material. If; on inside the tube or Rohres maintains a sufficiently high column of liquid so that they at least about the places where the transverse seams or seals are formed should reach out, each pack can also be completely filled with liquid will. If you want to empty the contents of such a pack, it becomes part of the pack perforated or cut open or cut so that an opening is created through which the contents can be poured out or sucked out.

Such packs are widely used in dairies, especially for the distribution of milk to the single traders. Become the apparatus for forming and celling the packs and also the packaging material shortly before or suitably sterilized upon entering the form and filling machine, then you can have a sufficiently sterile pack sterilized or with ultra-high Temperatures of treated or pasteurized milk.

An advantageous further development of such disposable packs for expansion of the scope is Zirl of the invention.

An essential characteristic of the present invention is a form of an already filled, essentially sterile disposable packaging, which has a sucker as an attachment or an integral part, which has a uniform Forms structure with the pack.

The teat can be used before, during or after molding, filling and sealing the pack can be formed in this itself, the packs consisting of a tube or a tube can be shaped and cut that is moveable from a tape or Strip of packaging material has been formed or blow molded can be.

The liquid can be water or a drink or a liquid food such as those used, for example, for the sick or infants. Such liquid food can be sterilized or pasteurized or with ultra-high Temperatures are treated.

The invention also includes a disposable package with an attached or integrating strap or extension that can also be used as a suction cup can and forms a uniform structure with the packing.

Another feature of the invention resides in the molding, filling with liquid and sealing a package and attaching it or forming a tab or extension, which forms an integral part of the pack, also Can be used as a teat and has a uniform structure with the pack forms.

If the packaging material is damaged during the molding and filling of the Pack sterilized at least on the side that will be the inside of the pack or can be made aseptic and also the liquid in sterilized or can be filled in a sterile state, the present invention provides Possibility of an essentially aseptic pack or an aseptic carton for liquid food supply.

As is known, the usual preparation of nursing bottles requires a lot of time and work. The bottle itself is usually made of glass and must sterilized after each use. That means every bottle after use cleaned and then either in the autoclave or by immersion in hot Water needs to be sterilized. Care must be taken that the bottle remains sterile until next use. If the bottle with the right amount the suitable liquid food is filled, a teat is put on, which is usually made of rubber and also cleaned and kept sterile got to.

Before the bottle is given to an infant, what is in it must be Food also have an appropriate temperature. The present invention enables the production of a filled, essentially sterile disposable package, which, if necessary, only needs to be heated to essentially consume the contents to bring the right temperature.

Then the tab or extension can be washed and, if necessary, treated with a sterilizing liquid an end best with a sterile instrument, appropriately perforated and as Suckers can be used. Each pack can be prepared essentially full and sterile and are closed and thus results in a package that is without risk of spoilage or the infection can be stored for quite a long time. This also makes it possible to prepare these packs in a central point in a mass operation, too fill and distribute it over a large area. Also can be a pretty big one Number of packs of different volumes with different types or compositions of food for the disabled or infants or the like at a central point be prepared economically.

It is true that no aseptic pack is obtained if the stage of sterilizing and disinfecting that area of the packaging material, which forms the inside of the pack or carton, omits; nevertheless one can Such a pack or box can still be valuable, especially if the one contained therein Liquid is pasteurized or sterilized because it represents a hygienic one Packaging, the contents of which represent little or no risk of infection by pathogens Organisms running. If the distribution conditions are favorable, it is superfluous to To take the aseptic precautions just described, and pasteurized or non-heat-treated liquids can be placed in the package in the same apparatus can be filled with a teat-like extension as used for the manufacture and filling of packages is used under aseptic conditions.

If necessary, each pack can be aseptically, conveniently in a elastic outer container or bag are placed and sealed; this The container is best made of thermoplastics such as polyethylene, and is only removed immediately before use of the disposable packaging. Such a The outer container can also be the disposable pack during any heating for preparation and only before perforating the flap or extension removed. This way the outside of the tab or extension can be kept free of external bacterial contamination until immediately ready for use will.

The packaging material is best a thermoplastic plastic of adequate thickness, strong enough to allow the pack to be tampered with and to endure the infant's activity if the tab or extension is considered Sucker is used.

The packaging material must also only have a low permeability for gas and must be impermeable to liquid. Suitable provided Materials include, for example, polyethylene, polyvinyl chloride, polypropylene. Thicknesses up to 1/8 inch are provided. Different colored materials can associated with different amounts or varieties or compositions of the content will.

In an arrangement according to the present invention, a tape or Strip of packaging material pulled from a roll, sterilized, into an apparatus ml * controlled atmosphere introduced and then around a thorn tid in an outer tube itself formed into a hose or tube; thereby will formed by welding a longitudinal seam, which the ends of tape or strip united. Inside the mandrel is a liquid supply tube that is below protrudes beyond the thorn.

Liquid is fed into the tube of packaging material, which e forms a sloping vertical column; the inflow is regulated by a valve, again by a float at a level above the outlet opening of the feed pipe is controlled. Quar running sealing jaws are located under the outlet opening of the feed pipe attached, which run across the tube of packaging material and on top of each other to be moved and brought into contact with the tube to make it a series of To close, form and seal packings; each pack has one End of a longitudinally extending tab or extension that acts as a suction cup should serve.

In another embodiment according to the present invention the tape around a mandrel, as previously described, into a hose or tube shaped; but instead of having the supply of the liquid controlled by a float is measured by a metering device at time intervals into the feed pipe given, which are coordinated with the activity of the sealing jaws. With this arrangement a certain amount of air or gas is trapped in each package, with this Amount can be relatively small.

While in the arrangement described above, the amount of liquid in each pack finally and mainly by the distance between the successive ones seals is determined, the amount of liquid is independent with this arrangement determined by this distance. Forming the tape into a hose or tube and the filling can be done in a device that is initially cleaned with hot air can be sterilized. The device can also continuously sterilized air or an inert gas are supplied so that the in each Trapped air or the gas is sterile in the pack.

All packs can, if desired, in the same direction or but initially shaped back to back in pairs. For this purpose you can essentially straight and transverse sealing jaws are provided, which a Piece of filled hose or pipe, the total length of two packages, seal and seam; on a later station before or can be provided after the separation of the double packing piece from the pipe of the middle piece of this double length can be shaped and formed into an edge, part of which runs transversely to the pipe for the greater part of its length and in a U-shaped or inverted U-shaped seam runs in, which itself in or near the the longitudinal edge of the pack facing the rain enters; this U-shaped or vice versa U-shaped part serves as a tab or extension. Will the tube in double packing pieces then it is best to be on both sides of the Pipe in Pressure blocks attached in the middle to reduce the amount of fluid in them and so keep the material waste low.

To the danger that # the extension when used as a suction cup is flattened or closed, to avoid or at least to reduce, It is best to make one or more folds, either on the long side next to the inverted U-shaped part in the transverse direction to this side and / or in the transverse. nth next to the inverted U-shaped part and in the longitudinal direction running.

Such folds can, for example, be heated by means of one or more pairs towards each other and away from each other moving sealing jaws are formed, the one Limit the cavity, which is periodically connected to a vacuum source can be 0 when part of the wall of a pack comes into contact with the jaws comes, part of the wall is sucked into the cavity when the jaws against each other pressure and thus a crease is formed.

In one modification, the tab or extension is not referred to as a Part of a transverse seam but formed in the long edge or side of each pack. Such a tab or extension can either be replaced by a similar one, above in Connection with the wrinkling described vacuum and heating process or formed by longitudinal jaws that shape the side of each pack and unite so that they are one side or form a longitudinal seam that includes a straight part that begins at a transverse seam that forms a U-shape Part that delimits the tab or extension, and to another:; eraden Part leads that ar. the next cross seam ends; excess packaging material is removed, with this arrangement straight, transverse sealing jaws are and the side or length seams that delimit the flap can be on the same Side of each pack or alternately work on opposite sides, or two pairs of sealing jaws sealing in the longitudinal direction can be provided. If desired, in addition to the connection point of the tab or extension with the transverse side seams are formed in the same way as pleats previously described, or an annular fold may be formed in a similar manner which includes this junction.

If longitudinally heatable jaws are used, the jaws are harnessed before the tape or strip becomes a tube or pipe is formed, in this case the tabs are formed in gaps, corresponding to the length of each pack and in sync with the transverse seal so that a tab protrudes from the side of each pack. That way formed pocket can be in the same plane as the transverse seals lie or on a plane that is perpendicular or at any angle to the Transverse seals level lies. Optionally, the heatable jaws are arranged in such a way that # »only form the side flap after the tape or the strip is longitudinally welded and a hose or forms a tube. Alich can be the side gap before or after filling and the heat sealing in the direction are increased. The preferred method is therein, they are in the same plane as and at the same time rlit the lower transverse Form seal0 The side flap can be on alternate sides on top of each other following packs or they can all be formed on the same side?

In a further embodiment, the tab or extension is provided in packaging material before it is formed into a hose or tube will. In this arrangement, packaging material is drawn from a feed roller and sterilized, then it runs between a roller and a source of heat, e.g. an infrared heater. The packaging material is then moved forward in batches and passed over a cooled roller, which has a recess on one part, which can be connected to a vacuum source.

The heated packaging material is deformed so that it is underneath the effect of the vacuum brought into the recess a larch or extension forms. To make it easier to pull the tab away from the recess, the Axis of It is best to face the recess slightly backwards inclined to the direction of travel of the packaging material, so that during the next pushing movement of t. Material, the vacuum source is separated from the recess, possibly Air, preferably under low pressure, can be passed into the recess make it easier to pull the tab out of the recess.

The strip or tape of packaging material is then around a mandrel and formed into a hose or tube within a tube. The tube has a longitudinal slot with open ends to allow free passage to allow the tab or the extension. The edges of the strip or tape are welded together so that they form a vertical tube. A supply tube for liquid goes through the mandrel, and the flow of the liquid through this tube is a float above the outlet opening of the tube or controlled by a previously described dosing device, below the opening the pipe is attached at least a pair of transverse sealing jaws, the Place transverse seams or seals at intervals on the pipe, creating a row is made of filled packages, each with a flap serving as a teat own.

While in the arrangement described first, the pockets or extensions usually protrude lengthways from each package, the tabs or protrude Extensions with this arrangement laterally or transversely. Will the roller in the area around the recess in which the tab or extension is formed is cooled, the packaging material in this area becomes essentially one permanent seat communicated and thus avoided that tab or extension when using as a sucker flatten or close up0 Under certain circumstances, the sucker also manufactured separately from the pack and then welded or welded to the wall be attached to it0 According to a further feature of the present invention a tube is formed from a tape or strip of packaging material, liquid filled in and then the pipe is sealed, shaped and cut at certain intervals, so that a series of filled packs are formed, furthermore at intervals a number of teats attached, at least one for each pack.

The suction cups can be welded, for example, or with a suitable Glue to be attached. It is best to do this before filling with the liquid or after filling with the liquid and before sealing, shaping and cutting.

But they can also be attached to each pack after cutting will. The heat required for welding can e.g. heated surface or a heated gas stream brought up or through inside the use of ultrasonic waves or a high frequency electric field be generated. The suction nipples can be injection molded by blow molding or vacuum molding a continuous ribbon or strip of packaging material, predominantly one thermoplastic plastic, suitable materials are provided include, for example, polyethylene, polyvinyl chloride, polyvinylidene chloride, polypropylene, Rubber and ethylene vinyl acetate.

In one arrangement for making the nipples for each pack this sucker around a flat integral flange at right angles to the longitudinal axis the open end of the shaft.

The suction cups can be inserted through holes that are large enough to allow the rounded end and shaft of the teat to go but the flange. The holes can be made in the tape or the Strip of packaging material or cut into the tube before filling 0 Then the suction cups can be welded or another suitable method around the flange that lies on the inside of the packaging material connected to the packaging material.

With this arrangement, the packaging material other than the various thermoplastic materials also include layered material, e.g. B. paper, which is covered on the inside with a thermoplastic material, and the Packs can be tetrahedra0 Another method is to cut the hole and the edge of the strip around the periphery of the hole towards a flange forums, the d @ r at right angles to the strip stands out0 This one The flange is then inserted into the hole after the shaft part of the suction device has been inserted welded to this.

In this case, the suction cup does not need to be provided with a flange to become. Both can be used to provide additional security when fastening Methods, hole with flange and suction cup with flange, to be used together0 At Another arrangement is to have matching holes spaced apart in the tape or the strip or cut into the tube of the packaging material and the teat attached with flanges on the outside to cover the holes. The holes can be very small to the flow rate of the liquid from the pack to restrict in the teat, or else they have a larger diameter up approximately to the inner diameter of the suction cup shaft part.

The teats can be used under aseptic conditions or after molding be produced, e.g. BO by means of a sterilizing liquid such as hydrogen superoxide, or by heating, in an autoclave or by irradiation with P or y rays sterilized and can be welded to the pipe in a sterile atmosphere, so that when welding to a sterile tube or a sterile pack, a completely aseptic pack. To use this chimney, if necessary, after heating the contents, in any convenient way, e.g. with a sterilized instrument, perforated at the outer rounded end of the teat will.

Another embodiment uses flanged suction cups at suitable intervals by welding or other suitable methods on the Outer surface of the packaging material attached, and the part of the wall of the packaging material, overlying the flanged end of the teat is at the time of manufacture of the filled packs not perforated0 The flanged suction cups can be placed in front of or after forming into a tube at suitable intervals on tape or strips of the packaging material They can be attached before or after filling with liquid or after after closing and before or after cutting to be attached to each package.

With this embodiment, the nipples do not need to be sterile, to get a sterile pack that allows the storage of a sterilized content Permitted for a long time at normal temperature. It just has to be taken care of that the tape or strip is made sterile on the inside and then made is aseptically filled with a sterile liquid, for the part of the wall that above the flanged end of the teat acts like a seal and prevents that the contents of the pack with the surfaces within the until it is used Cavity of the suction cup comes into contact Usually it is sufficient that the flanged one Teats are manufactured and treated hygienically1 to avoid their contamination with pathogens Avoid germs until they are attached to the packaging material. Leave it but also situations foresee where the sterility of the teat must be ensured, either by aseptic production, by treatment in a bath with a sterilizing liquid, such as hydrogen peroxide, by heating, in an autoclave or finally by irradiation0 In this case, care must be taken that the outer and inner x surface of the packaging material prior to fastening of the teat can be sterilized.

In a preferred feature of this embodiment of the invention can the rounded end of the teat before shipping the finished pack with a or several holes of a certain size, depending on the different ages and the state of strength of the children to be riddled with holes. Shall the bottle if necessary After heating the contents, the part of the wall that holds the pack can be used closes over the flanged end of the teat, in a suitable manner, e.g. B. with a thin, pointed, sterile instrument that runs the length of the teat pierced as often as necessary. Such an instrument can be through an already existing perforation in the rounded end of the mammal or pushed through the material and then forms an additional hole. will this additional hole with. made with a very thin instrument, e.g. a sterile needle, then it has the tendency to close when it is withdrawn and not an unpleasant one Allowing an increase in the rate of flow from the nipple is an advantage This preferred method with pre-formed holes of the correct size is the It is a fact that there is no special tool for the consumer to puncture must indicate and the disadvantage of variable holes does not occur A The disadvantage of the previously perforated teat is that it is distributed during the distribution and when the contents are heated, e.g. B. in a warm water bath, dirt, moisture and microorganisms can enter the cavity of the teat.

This disadvantage can be remedied by removing the packing, be it aseptic or not, in an elastic outer container or bag, best made of thermoplastic material, such as polyethylene, sticks and closes, which is only removed immediately before the pack is used. In this way can be the inner and outer side of the previously perforated teat or the outer surface a non-perforated nipple free from bacterial until it is used Pollution are kept.

Another option, the teat attached to the pack up Keeping free of external contaminants at the time of use is the one Sucker, ideally as soon as possible after its manufacture, in a thin elastic to plug and seal the outer shell, which is best shaped so that it has a flat surface that extends beyond the flanged end of the nipple. These thin, elastic outer shell is preferably made of thermoplastic material, z * B polythene. While the suction flange by suitable means, such as Welding, attached to the packaging material, becomes the part of the wall of the The outer shell that lies over the flanged end of the suction cup is also on the flange and packing material under the flange and on the outside of the Sau3erelansehes attached.

After prior heating, the upper part of the shell is torn off and a suitable instrument, such as a sterile needle, through the entire length of the suction cup, with or without a pre-perforated hole, so that one or more Holes through both the wall part of the outer shell and the wall part of the Packaging material that is under the open surface of the flanged end of the teat lies, to be pushed.

As long as the packaging material is still in tape or strip form, identification or other labels can be printed on it.

In any of the above arrangements, the form and fill apparatus preferably housed in a suitable container, in the during operation sterile air is constantly being stirred in; the device is best designed so that heated sterile air is introduced throughout the container, so that the entire The apparatus is sterilized before the start of production.

The packaging material can be treated with a sterilizing agent Liquid, e.g. B. hydrogen peroxide, sodium hypochlorite, hypochlorous acid, ChlordioxydX, which are sprayed on tape or strips, or sterilized Tape or strips can pass through just before they enter the container Bath can be passed with a sterilizing liquid. Then the Inside of the packaging material can be heated, either by one on the Heating element attached to the outside of the liquid supply pipe, or by placing tape or strips between a roller and a heat source, e.g. B. a Infrared heating element, passes through to the sterilizing liquid located on it to vaporize or decompose, making the inside of the tube sterile. One leads sterile air under positive pressure into the container, in which the molding and filling takes place, one can sterile air through the inlet opening for tape or strip let escape, the then-all products of the sterilization of the sterilizing liquid takes with it, In any of the arrangements described above, the sterilization can also be done by exposure to ultraviolet, x-rays, or rays. The packaging material can be sterilized by irradiation while still on the roll and then passed into a sterile container where it is shaped into a tube, is filled, sealed or preformed.

Another suitable method of sterilization is that one side of the tape or strip is rapidly passed through a flame while at the same time a coolant acts on the other side of the tape or strip. The sterilization is carried out first on one side, then on the other. The time that one side of the tape or strip is in contact with the flame comes, must not take longer than necessary for the destruction of bacteria or others Microorganisms on the side may be necessary.

Another type of sterilization in the same way etst on the one, then the other is the application of high frequency high voltage spark discharge.

In another method according to the present invention Packs and acidic blown with sterile air from a tube that goes straight out an extraction head and was at a higher temperature than it was for the destruction of spores is required. The mold has a suction-like mixing cavity, which allows the formation of a Sauxer-like tab.

After the glass molding and before removal from the mold, one is sterilized or liquid food or beverage treated at ultra-high temperatures. ink is fed into the pack through the same feed tube as for the blow molding air.

The parts of the machine that make the extraction head and blow mold or molds include, as well as the transfer mechanism, whereby the extracted pipe sections to be brought to the molds are enclosed in a housing that is pre-operated is sterilized by hot air or steam and sterile by constant supply Air is kept sterile.

Another feature of the present invention is manufacture a series of individual, separate, disposable packs made of thermoplastic Plastic can be preformed and each of which is formed in the wall or on the Wall attached has a tab or extension that can be perforated and can serve as a sucker.

Furthermore, each preformed package is sterilized, a specific one Amount of liquid food introduced and then the preformed package closed and sealed in a sterile atmosphere. The sterilization can by dipping in or spraying with a sterilizing liquid and refilling Heating can be carried out in order to vaporize the sterilizing liquid and / or to decompose.

The invention will now be described, by way of example, with reference to the accompanying drawings Drawings are described below.

Here, the tape 10 can be fed continuously or intermittently werden0 If the tape is fed in intermittently, the jaws 34,36 can be used to close placed at a fixed height and brought into contact with the pipe when The pipe and tape are at a standstill, and the heat sealing device 26 must only be intermittent placed on the first material in order to avoid overheating. But move the belt 10 and the tube 28 or hose continuously, then the jaws must 34,36 besides their lateral movement they can also execute a vertical movement, so that they are essentially in the. Can move in unison with the pipe 28, when they do their sealing work.

Purpose of the bath 16 with sterilizing liquid and the container 18 is to be able to make the tube 28 sterile. For this purpose, all parts that can come into contact with the inside of the tube, inside the container 18, and before the start of production can be used for the purpose of sterilization means sterile air can be introduced into the container 18 by a device not shown. Even if sterile air is continuously introduced into the container 18 during manufacture has to be, it doesn’t need to be heated. To the inside of the To make the tube 28 sterile, the one received on top of the band 10 must be Sterilizing liquid may evaporate or decompose. This can be done by heating of the mandrel 22 or by attaching an outer tubular heating element in -eniigend Distance done around the mandrel through which the tube 28 can pass. Optional but can also a radiator can be attached over the guide 20. The jaws 34,36 can be shaped so that they have a straight closure at the bottom a pack and a partially straight closure with a tab or an extension at the top of a second pack.

One way in which the packages can be shaped is in FIG. 2 shown schematically. A pack 40 is partially straight at one end Lock # 44 and a partially curved lock that is a tab or extension 46 forms0 The following pack 40A also has a closure 42A on one end and a partially straight slot 44A at the other end with a tab or extension 46A. The jaws 34,36 can be shaped so that they the upper partially straight closure # 44 and the pocket 46 of the one pack and the lower one Form straight closure 42A of the following package at the same time0 It is best the jaws arranged so that they press the sides of the tube together over the surface 48, but not necessarily close; if desired, they can be arranged that way be that they run the tube along the outer edges of the seams 42A, 44 and around the extension Prune 46 around and separate one pack and the next when this separation can also be done at a later station if desired.

In an optional arrangement, the jaws 34, 36 can be so arranged be that they only close the sides of the tube 28 and so a number of Donpelpackunosstäcken deliver, with each piece then afterwards on a later Station, e.g. through the other jaws 34A, 36A, as in FIG. 1 shown being formed into a pair of packets.

The method by which twin packing pieces can be formed is shown schematically in FIG. The jaws 34,36 are arranged so that # they cause at 50 on the upper part of a double packing piece a closure that a may be composite closure, namely an upper closure 52 at the top Part of a double packing piece and a bottom cap # 54 on the lower part of the next Donpel packing piece. If the tube 28 moves downward, then it gets caught the middle portion 56 of a double packing piece, e.g. 13. 58, in the area of another Pair of jaws 34A, 36A. These cause a partially straight ttaht 66 on the upper part a lower packing piece 62, which also delimits a tab or extension S4, and a partially straight seam 66 on the bottom of another package 68 and bounded the tab or extension 70. Portion 72 of the tube is then severed and thrown away. This separation can be through the jaws 34A or 36A or on a later station can be effected. As part of this production method of the packs 72 is thrown away, it is best to install cushions on an earlier ward, which compress the sides of the tube over an area indicated schematically at 74, so that the volume of the double pack is reduced accordingly. These pillows only need to press the sides of the raw @ together and do not necessarily have to be in the position indicated in FIG.

Around any inclination of the pocket or extension that serve as suction cups should, or to prevent or at least reduce a collapse, can in near where the tab or extension meets the rest of the pack connects, one or more folds are formed in the packaging material. this is shown schematically in Figs. In the case of the pack shown in FIG is a straight seam 82 at the bottom and a partially straight seam 84 at the top.

In the side wall of the tube is near the connection of the tab or extension 88 a fold 86 is made with the remainder of the package. In addition, in the region of the straight part of the upper seam 84 near the joint A second fold 90 is attached between the tab 88 and the rest of the body. These Folds can be made at the same time as the seam 84 or separately Points corresponding to these folds 86s90 are shown schematically in FIG. 3 at 86A and 90A specified. These two folds cause the junction between the tab or extension 88 and the body of the pack is held open, too With only one such fold, it is still possible to keep the base of the pocket open. If a new fold 86 is made, the junction between the tab or Extension 88 and the body will usually be triangular as shown schematically at 86B indicated in FIG. 5.

On the other hand, if only the fold 90 is made, the joint becomes also be triangular but point in the opposite direction as indicated at 90B.

These folds can be made using a vacuum and heat welding process will; an arrangement of such a former is shown schematically in FIG.

Two heatable jaws 61,63 are towards and away from one another movably mounted in a slide rail, which thereby the side pieces 65,67 and a rear wall 69 is limited so that when they are separated, for Part of a cavity 71 delimiting by a pipe 75 passing through the rear wall 69 communicates with the inside of the cavity, with a vacuum source 73 can be connected. Will the shaper against a wall or the walls of the pack pressed, with the jaws 61,63 open and the cavity 71 with the vacuum source 73 is connected, then part of the wall or walls is sucked into the cavity; the vacuum is released and air is let into the cavity through a valve 77, the Sealing jaws come loose and there is a fold in the wall or walls of the pack in addition to one or both of the folds 86, 9Q, like them are shown in Fig. 4 and 5, further laterally reaching folds, to be provided at right angles to those so that the junction surrounded by a series of folds between the flap and the rest of the pack that form a polygon. In one modification is the junction of the flap or extension surrounded by an annular fold, and in Fig0 7 is a device for molding this annular fold schematically shown. A front wall plate 81 is provided with a series of radially extending Gluten 83 is provided, and a heatable jaw 85 is slidable in each of these grooves built-in ; In the middle there is a central opening or recess 89 around an annular disc 87. Outside the disc 87 is an annular Cavity 91, which can be as deep as or deeper than the grooves 83; the floor the cavity 91 is through one or more tubes 95 and a switch valve 97 with a vacuum source 93 is connected.

In operation, the tab or extension of a package is inserted into the central opening 89 inserted and the wall or walls of the pack containing the junction of the tab, against the washer 87 and the surfaces of the plate 81 and the jaws pressed; Valve 97 is actuated to close vacuum source 93 with cavity 91 Connect, and an annular fold of packaging material is made into the cavity sucked in; the jaws 85 are pressed radially inward and form an annular one Fold, valve 97 is operated to separate the cavity 91 from the vacuum source 93 and to let air in, the jaws 85 are retracted radially outward and the package removed It is not essential that the tab be in or at one corner of a transverse seam of the pack or on one side of a Such a seam is attached, as shown in Figs. 2, 3, 4 and 5. The flap can at any point on the transverse seam or at any point on the long side attached to the pack as shown in FIGS. 7, 8 or 9.

Fi. Fig. 8 shows schematically how transverse jaws that the jaws 34,36 in Fig. 1 are similar, but narrower, by essentially straight transverse seams 43, 43A, 43B a plurality of packs 41, 41A can be formed. A longitudinal, pathetic one The pair of jaws can then be pressed against each other, whereby these have a side strip of the package and form a seam that has a straight portion 45A, one after outer running U-shaped part 47 and another straight part 45B. Where The U-shaped part 47 delimits the tab which is later to serve as a suction cup. Excess or unnecessary material 49 is removed. The longitudinal seams do not have to be irrimer can be formed on the same side of the pack, but as in Fig. 9, switch from side to side.

To prevent the pocket from flattening when used as a suction cup or closes, can be in the near the junction of the tab in the previously in connection with Fig, 4 or 5 or 6 described manner one or more folds be introduced into the packaging material. Optionally, it can also be around the connection point the pocket around by a former, as shown in Fig. 10, an annular Crease 51 can be formed. Such a package is shown at 55 in FIG.

In the arrangement shown in Fig. 11, the pocket or extension formed from the packaging material by a vacuum before it is formed into a tube will. Packaging material 10 from a feed roller 12 runs through a bath 16 sterilizing Liquid and then into a container 18 where it runs over a roller 100 and under an infrared heater 102.

Tape or strip 10 is intermittently mushroomed by a pair of 104, 106 is advanced, and after it has passed over roller 100, it is passed over a second roller 108 passed, which is best cooled and one reaching down Has recess 110 which is provided by a valve 112 with a vacuum source, e.g. Vacuum pump 114, is connected. When the belt 10 comes to a stop above the roller 108 comes, the valve 112 is open, and the packaging material, which is after Running winter the radiator 102 is in a softened state, is shown in the recess 110 is sucked in and forms a tab or annulus 116. From the next thrust of movement of the end 10, the valve 112 is closed nd can let sterile uS flow into n recess, so that the tab 116 comes out the recess 110 can be drawn. Since the roller 108 is cooled, in the area of the connection between the tab or extension 116 and the tape or strip 10 permanent deformation of the packaging material. The stripe or the belt 10 is transported further by the roller 104, 106, and the roller 104 is hollowed out accordingly or consists of two aids to the flap or Let extension 116 through.

Strip or tape 10 is passed around a mandrel 22, and the Ends through. a welding device 26 connected to one another, that a pipe 28 form. In addition to mandrel 22, an outer guide tube 118 can also be installed, as shown schematically in Fig. 6, and this tube is provided with a Longitudinal groove or a slot to allow passage of any tab or extension. Inside the mandrel 22 is a feed tube 30 through which the by a float 32 controlled fluid flows. Located below the bottom of the feed pipe 30 a pair of jaws 120 for closing the walls, for welding the pipe, for a series of single packs 122.

In addition to heating the packaging material 10, the heating element is used 102 also places any sterilizing liquid on the top surface of the strip or to vaporize or disintegrate the tape 10 to make the tape sterile. The container 18 is also provided with a feed tube 124 for introducing hot sterilized ones Air provided to pre-production the various parts that come with the surface of tape or strip 10 can come into contact to sterilize. While The operation does not need a hot sterile liaft to be introduced, you can go through Introduce cold sterilized air into tube 124 or a special tube 126; the pressure in the container 18 is high enough above the surrounding atmosphere so that sterile Air through the inlet opening for tape 10 and the outlet opening for the Packs 122 can leak; in this way the penetration becomes more non-sterilized Air in the container 18 avoided.

It is not absolutely necessary for a constant column of liquid in the tube 28 must stand #. In the case of a modification, the float 3 @ we @ has been left, and the feed pipe 30 becomes through a dispenser with liquid fed, which is timed with the operation of the jaws, so that one beforehand a fixed amount of liquid is added to each package.

-It is also not absolutely necessary that the pipe 28 is an im has a substantial vertical axis, the packs can also be closed, while continuously or intermittently moving itself horizontally move, provided there is enough static fluid gradient in them maintain.

Another method of forming packs from a ribbon or strip of packaging material is shown in Fig. 12 2.

A tape or strip 250 of packaging material is taken from a Supply roll 252 over a guide roller 254 through a bath 256 with a sterilizing Liquid like hydrogen peroxide, drawn. After leaving the bath 256 runs the tape through an inlet port into a container 258, for the purposes of clarity only sake is shown schematically. The tape or strip runs between nip rollers 259, over a shaped guide 260 and is drawn around a shaping mandrel 262, so that its ends overlap as at 264 and then under a heat welder 266, thereby forming a longitudinal seam that pulls the tape into transformed into a tube 268.

Runs through mandrel 262 to a point below the welder 266 a feed tube 270 through which a liquid filling is introduced. A Float 272 is used for Control of the flow rate of the Filling liquid, so that there is always a column of liquid in the tube. One piece Below the sand of the feed tube 270 are a pair of laterally reciprocable heatable jaws 274, 276 attached; although only a pair of these sealing jaws is shown, multiple pairs can be provided at intervals.

Next to the mandrel 262 there is a storage container 278 for suction cups, which gives the teats piece by piece in a teat holder 280, which is horizontally movable is from a position that is matched to the storage container 278, or in a position in which a suction cup is in contact with the outside of the tube brings to form a pack. Is the vacuum holder on the storage container then it is best to be in a vertical position, as in Fig. 13 indicated at 280; he is then moved laterally to a sucker 282 with Bringing the packaging material 268 into contact, it goes, as shown in Fig. 13A, from a vertical to a horizontal position 280 A. The teat holder 280 has in the area of the edge of the recess for receiving the suction cup Heater 284 so that when there is a sucker against the wall of tube 268 presses, a weld can be made between the suction cup and the pipe.

The teat can be attached to the tube before it is filled with liquid is filled. But it can also be attached after covering with liquid, before the pack is sealed, shaped and cut. The teat holder can therefore deeper be attached below the jaws 274, 276, such as shown in dashed lines at 280B; in this case the jaws 274, 276 not only for closing the upper end of one end and the lower end the other Pacimg, but also a device for separating encompass one package from the other.

In a further arrangement, the heatable jaws 274, r76 just the sides of the tube1 so that they are the top of the one and the bottom Form another pack if the packs are laterally movable by a pair Cutting knives 286, 288 are separated, these knives would be a little deeper as jaws 274 276 and are shown adjacent to FIG. 12 for clarity only. Of the Sucker support 280 may be lower than knives 286, 288, as at 280B in dashed lines Lines are shown so that the nipple is attached to each pack after cutting and is attached. The suction cups can be made by injection, blow or vacuum molding shaped as a continuous tape or strip and also self-sterilized before they are placed in the storage container 278, which is inside the bulk container 258 is set up.

One form of pack made with the device shown in FIG can be achieved is shown schematically in Figure 14, the packing 280 of which has a longitudinal seam 292, an upper weld 294, a lower weld 296 and, on one side attached, has a sucker 298. 15 is an enlarged view of the daugers and wall 300 is shown. The sunger is with a flange 302 provided, which abuts against the wall 300 of the pack and with her, as at 304 schematically shown is welded. Part 3o6 of the wall of the pack, that of the inside of the Suction 298 corresponds, remains unbroken. When the pack is emptied the outer end part 08 of the teat and part 306 of the wall of the pack be perforated or pierced with a suitable sterile instrument1 Das Belt 250 can be transported continuously or intermittently. It will Belt 250 transported in batches1 then the jaws 274, 276, the suction cup carrier 280 and the cutting jaws 286, 288 are each attached at a fixed height, and can be brought into contact with the pipe when the pipe and tape are silent stand. The welding device 266 is only allowed to come into contact with the material for a short time come to avoid tfl> heating. But belt 250 and tube 268 move continuously, then jaws 274, 276 and 286 and 288, if they are present, and the sucker support 280 in addition to their lateral movement can also still be moved vertically so that they are essentially in accordance move with tube 268 when performing plugging and / or cutting operations.

The bath 256 with sterilizing liquid and the container 258 are intended to enable the tube 268 to be sterilized. To this end, everyone will Parts that may come into contact with the inner surface of the pipe, within of the container 258 and before the start of production can be used for the purpose of sterilization name is sterile air is brought into container 258 from a device not shown will. It is true that sterile air can enter the container continuously during operation 258, but it doesn't have to be hot. To the inside To make the tube 268 sterile, the top of the tape 250 must be bathed 256 absorbed sterilizing liquid are evaporated or decomposed. this can be done either by heating the mandrel 262 or by attaching a tubular Radiator at a small distance around the mandrel 262, so that there is enough free space remains for the passage of the tube 268 take place. Optionally, a Radiator can be attached over the guide 260.

If desired, that the wall of the pack is removed during manufacture and filling to be pierced, holes can be made in packs before molding attached to the packaging material and suckers inserted through these holes and then welded to the packaging material.

In the arrangement shown in FIG. 16, packaging material runs 250 from a feeder roller 252 through a bath 256 with a sterilizing fluid, enters bin 258 and then passes over roller 310 and under Infrared heater 312. Ribbon or strip is made by a pair of Walsen 314,316 The belt is moved forward in batches after it has passed over the roller 310 is brought over an embossing block 318, which cooperates with a punch 320, the ia temporal coincidence with the rotation of the rollers 314, 316 is moved up and down and so each state a hole in a piece of packaging material, that corresponds to a pack. The next time the rollers 314, 316 are moved the tape 250 is advanced so that the punch 320 and die block 318 in cooperation with a support part 322 and a teat support 324 cooperating with them which both move towards and away from each other in a vertical plane can move back and forth. For each pack, the carrier 324 receives a teat a storage container, not shown. When the rollers 314, 316 come to a standstill the support member 322 will be up against the underside of the tape or strip 250 and the carrier 324 brought down vertically so that the sucker is off the belt or strip is pushed out and into a recess in support member 322. Of the The carrier 324 or the support part 322 or both have a deicing device for welding between the tape or strip and an inserted suction cup. The support part 322 and carrier 324 are then moved apart so that the nipple is out of the support member 322 is released. With the subsequent movement of the rollers 314, 316, the strip or the tape 250 is passed around a mandrel 262 to form the tube 268. Additionally A guide tube shown schematically in FIG. 16 can also be provided for mandrel 262 will. This has a Lkngsnut or a longitudinal slot that the passage Each suction device 33Q allows inside mandrel 262 a feed tube 270, whose fluid flow is controlled by a transducer 272. Under the end of the feed tube 270 is a pair of jaws 332 to get the Cap the tube and form a series of individual packs 334.

The heating element 312 is also used to heat the packaging material 250 also there, sterilizing liquid on top of the strip or tape 250 to vaporize or decompose to make the tape sterile and the container 258 has a supply tube 336 for introducing hot sterile air for sterilization all of those one with that area of tape or strip 250 that is the inside of the pack, or will form with the inside of the pack, or with come into contact with the inside of a suction cup. This sterilization happens before production. The nipples are also best sterilized before being given to the wearer 324 can be supplied. If sterile air continues to be supplied, whether hot or cold, and the pressure within the container 258 sufficiently high above the surrounding atmosphere is maintained so that the sterile air through the entrance opening of the tape 250 and the exit opening for the finished packs 334 can then exit the packs are formed, filled and sealed under aseptic conditions. This is important when filling the liquid itself before entering the feed tube 270 has been sterilized or treated at ultra-high temperatures.

In none of the embodiments shown in Figs. 12 and 21 is it essential obtain a column of liquid in tube 268; therefore the swimmer 272 are glass and the feed pipe 270 with a dosing device, which is timed with the Operation of the heating jaws 274 and 276 or 332 and others operated intermittently share is coupled, connected; the packaging can also be closed, if the packages move even in a horizontal direction, if only enough static gradient of the liquid in the packings is maintained.

The suction cups can be made with a substantially flat, integral flange 340 are shaped, which is substantially perpendicular to the longitudinal axis of the tubular Shaft 342 and a rounded end 344, as in Pig. 17 and 19.

The holes made in the tape or strip 250 may be straight be large enough to accommodate rounded end 344 and shaft 342, but not Let flange 340 pass.

Such a relationship is shown in Fig. 17, which shows the margin is greatly exaggerated. The flange 340 lies on one side of the tape or strip 250, which will form the inside of the package, and is welded to it. Optional can cut the hole and the edges of the strip around the periphery of the hole can be shaped around a flange 348 that is perpendicular to the tape or strip 250 hln protrudes. The suction cup doesn't need a flange, just one To be provided with shaft 342 and a rounded end 344; the shaft is with welded to flange 348 after the nipple is inserted into the hole. Such an arrangement is shown in FIG. The vacuum cleaner can also be used with a Flange 340 and the tape or strip can be provided with a flange 248 so that not just between flange 340 of the teat and a page of the band 250, but also between flange 348 of the band or strip 250 and is welded to the shaft 342 of the teat.

In the arrangement shown in FIG. 12, the suction cup is on the outside attached to the pack so that # to empty the contents through the nipple that End of the teat and also the part of the wall of the pack that is surrounded by the teat is sweet to be holed. On the other hand, in Pig. 16 violins Arrangement the wall of the pack already perforated; should the paokung be emptied only needs to be broken through the rounded end of the teat. It however, it may be desirable for the teat to be attached to the outside of the package if the wall part of the pack that is surrounded by suction cups is in one smaller dimensions than the inner cross-sectional area of the suction cup should be opened, a kind of Drassol valve to control the outflow speed of the liquid to have. Such a construction is schematic in Pig. 20 shown in the the tape or strip 250 is perforated to make a hole of relatively small size To have diameter 350, the one smaller; Has cross-sectional area than the Shank 342 of the teat that welded one to the outer surface of the pack Plansoh 340 owns. Such a construction can be achieved by doing that Support part 322 and the carrier 324 in the arrangement of FIG. 21 by a suction carrier 280 as shown in Fig. 12, but modified it so that it is a nipple brings up and in contact with the lower surface of the tape or strip 290, and by making a hole punch 320 and an embossing block 318 of smaller size diameter used.

Where the rounded end of the teat is before shipping the finished pack can be perforated in the arrangements shown in FIGS perforated teats can be used.

If one wants the risk of penetration of dirt, moisture and Can avoid microorganism into the nipple or cavity before use a pack placed in an elastic outer container or bag and sealed will; this outer pouch is not put into the pack until just before use removed.

It is also provided that @ da # the vacuum cleaner itself through beforehand holes and put into an elastic outer shell and then suckers and Sleeve to be welded to the outside of the pack. The one in an outer shell encapsulated acids can be used in the arrangement in Fig. 12, and is a detail view in section of such a pack on an enlarged scale shown in FIG. This nipple 360 includes a shaft 362 with a flange 364 at one end and a rounded end 366 at the other end; this rounded End is, as shown at 368, pierced or pierced. The Bauger is located located in a resilient outer shell 370 with a flat portion 372 extending over a flange 364 extends, a shaft-like part 374 which envelops the shaft 362, and a part with a tearable seam 376 nearby, but in a certain way Distance from rounded end 366 of the nipple.

The teat in its silence is packed with the outside 378 380 brought into contact. Heat and pressure are by means of one Pair of annular welders 382, 384 onto the flange of the shell, the flange of the teat and the wall of the pack 380. To empty the pack, will remove the upper part of the sheath 370 and use a suitable instrument, t. Legs sterile needle pushed through the entire length of the teat and one or more holes through both the flat portion 372 of the sleeve and through the wall of the pack 380 made, which lies under the open surface of the flange and suction cup.

Referring to Fig. 22, a drawing machine is schematically made shown at 300; it comprises a hopper 212, a feed screw 214, a pull-out sheet 216, further is a common heating device (not shown) provided to pull out a tube 218 of thermoplastic material. Pieces of the from the drawn tube are cut off, they then roll up in one of the two Molds 220 standing on the exhaust block. The mold then becomes its blow molding and filling station 224 or 222 where a tube 226 is in the top of the mold is inserted and sterile air is blown into it under pressure to make the plastic Press material against cavity 228 of the mold. The cavity of the form is like this formed that it has an additional cavity 230 on the side, whereby a Hollow teat-shaped flap as an integral part of the pack can be shaped. Such an additional cavity can be, as shown at 230, on one side or as shown at 232 and can also be seen elsewhere, are on the ground. After the pack is formed, the feed more sterile Air is removed and a liquid filling is introduced through tube 226. Then it will be the fill tube 226 is retracted and the mold opens. The filled pack sinks on a platform 234 down to a locking station where a pair of jaws 236 are brought together to seal and seal the top of the package. When the parts of the extractor 200 and the mold 220 and the jaws 236 into one Booth shown schematically at 238 with a device 240 for introducing hot, sterile air or steam before the start of production and afterwards Maintaining a continuous supply of sterile air to the cabin during the work included, and the liquid filling before the introduction to the Tube 226 is sterilized or treated with ultra-high temperatures, one can receive a filled, essentially aseptic pack with an integral teat, where the temperature in the case of combustible packaging material is below and near the flash point of the respective padding material.

The tube 226 can consist of two concentric tubes, one of which one to introduce air during blow molding and to ventilate the package is used while filling through the other tube. The jaws 236 can can optionally also be attached to the upper part of the mold and their locking work after retracting the tubes 226.

Another advantageous method for performing sterilization consists essentially in having one side of the Tape or Strip quickly through a flame while walking to the other side of the Tape or strip allows a coolant to act. The time in which the area of the tape or strip comes into contact with the flame, must not be longer than essential for the destruction of bacteria or other microorganisms on this Side is required to be, it is best to have one or more flames allf one Side of the tape or strip directed while it is on a nonlinear Path is best moved at a substantially constant speed; this 1, Path can preferably be from one to the other side of the tape or strip acting coolant are limited; the tape is immediately after the passage passed through the flame into the cabin, where sterile air is admitted. That Tape can enter through an opening or slot that the side of the Tape or strip that has been exposed to the flame or flames is a boundary forms. The sterilized side of the tape then forms an inwardly facing one Wall of the cabin, while the non-sterilized side is an outward-facing one Wall of the cabin forms.

In this way, the side on which the flame acted needs not to come into contact with the outside air before entering the cabin. The risk of such contact with the ambient air can be significantly reduced when aseptic air comes out of the slot. Another flame or several flames can now be directed to the other side of the moving band be while a coolant to the one treated first with the flames Side acts. This coolant has been sterilized before the start of operation and lies within the vessel or cabin, to that under superatmospheric Pressure sterile air is supplied.

In this way, one side of the moving belt will be in front of entry Sterilized in the cubicle, then the other side is sterilized before entering the cubicle sterilized.

Another kind, in a similar way first one and then the other Sterilizing side u is treatment with high-frequency high-voltage spark discharges. To this end, the moving belt can move over and in contact with one another rotating cylindrical electrode with internal grounded conductive layers, e.g. out of aluminum sheet. Then the tape takes a second in one short distance from the first attached electrode and below a third in Direction of travel of the tape and at a small distance from the second and similar an electrode placed a short distance from the tape or strip, so that the tape or strip has part of the dielectric between the first and each of the second and third electrodes forms, and the small air gaps form another part of the dielectric. A high frequency, high voltage waveform becomes more opposite between the second and the first and a second waveform Polarity introduced between the third and the first electrode, the two Waveforms are in phase relation to each other. The first waveform can an initial one High voltage peak with a steep leading edge followed by a longer tension of a smaller size. The long one The high-voltage impulse is supposed to hit the air dielectric and create a spark discharge cause between the second electrode and the adjacent strip surface that long voltage is supposed to keep this discharge going. The second waveform can also include a pulse with a steep leading edge and can, if desired, followed by a longer period of lesser voltage magnitude. Purpose of the second Waveform is one of the surface of the belt as it moves under the second electrode to release the voltage picked up and each into the conductive Layers of the insulated electrode to discharge accumulated charge. The sizes of the Waveform peaks can be around 10 to 50 tV and the repetition frequency the waveforms can be around 50 Hz. The tape is also partially in the cabin introduced so that its surface that is near or opposite the second or third electrode lay in the cabin under the action of the pressurized exposed to stagnant sterile air.

When sterilizing with the flame must be done accordingly. Precautions be taken so that the flames are only directed towards the tape or strip when it moves and not when it stands still. During sterilization a device for switching off can easily be provided by point discharge, when the tape stops.

In the event of a spark discharge through the air gap between the electrode and ozone is generated on the belt. While the presence of this ozone in the sterile Cabin can be a valuable addition to the sterilization process, but it can It may be desirable that the ozone does not come into contact with the food being filled to let come. This can be done, for example, by dividing the cabin into two by means of a Baffle disk happen, in which a narrow slot is cut that the transport of the tape from one department to the other. The supply of sterile air under superatmospheric pressure happens in the B-direction of movement of the tape second division and reaches the first division through the Slit in the control disk, creating an opposite direction of tape transport faster airflow is created, carrying every trace of ozone towards the slot and eventually through the slot through which the belt enters the first compartment. Outside Pressurized air ducts can be attached to the cabin and next to the inlet slots the ozone-laden air from the room in which the process is carried out will, from, suck.

The packaging material is best made of thermoplastic. fabric and should be thick enough so that one can handle it and an infant die Can use tab or extension as a suction cup. By means of the present invention it is possible to create a pack that contains a certain amount of liquid Contains baby food, the inside of the pack being aseptic is. left the pack has a tab or extension as an integral part, which can serve as a sucker.

If desired, each package can be converted into a relatively rigid outer Containers with an opening through which the teat can protrude. This outer container can be a shape made of thermoplastic or thermoplastic that remains open or is closed with a cap. Using a outer container is advisable to avoid the toddler holding the empty package soaks in. If such an outer container is a poor heat conductor, then it can They also serve to prevent the contents of the pack from cooling too quickly.

All new disclosed in the description and / or the drawing Individual and combination features are regarded as essential to the invention.
