The tobacco supply is designed as a dimensionally stable tobacco rod (10) which is adapted to the tobacco filling of the finished cigarette and as such is non-smokable but completely made of smokable material and is provided for the self-production of filterless or filter cigarettes. Preferably the tobacco supply (15) comprises an air permeable casing (13) made of smokable material, e.g. Tobacco foil material. A funnel-like sleeve (18) is used to facilitate the insertion of the prefabricated, dimensionally stable tobacco rod (10) into a prefabricated cigarette paper tube (11). The tobacco rod (10) can be easily inserted into the cigarette paper tube (11) through this insertion funnel (18).

Description

The invention relates to a tobacco product consisting of a pre-portioned tobacco supply which is surrounded by cigarette paper in a sleeve-like manner, and to a method and a device for producing such a tobacco product.

The production of cigarettes by the consumer has long been known in many forms. This applies above all to the so-called self-rolling of cigarettes using cigarette paper papers provided with adhesive rubber. Rolling cigarettes yourself requires a certain amount of manual skill and time. The cigarettes themselves are very different in size (diameter), strength (plumpness) and filling level over the length of the cigarette, even with practiced self-rolling, and are only a primitive replacement for industrially manufactured cigarettes. Another disadvantage of manual self-turning is the inevitable crumbling of tobacco, which also affects the tobacco yield. The same problems - albeit reduced - also occur when using self-turning devices.

The same applies to the other basic type of self-production of cigarettes, namely the self-stuffing of cigarettes. There are a number of more or less comfortable devices for stuffing cigarette tubes (usually with a filter piece) with tobacco, all common devices having an elongated pressing chamber in common, which on the one hand has an approximately semicircular fixed wall part and on the other hand an opposite semicircular surface of a movable press bar is limited, by means of which the press chamber can be closed after filling with tobacco to produce a strand-like tobacco supply. At one end of the pressing chamber there is a plug-in nozzle for attaching and plugging in an empty cigarette tube. At the opposite end, the press chamber is delimited by a piston-like tobacco ejection slide, by means of which the tobacco supply can be transferred from the press chamber to the cigarette tube (see, for example, DG-OS 2 833 681; DE-PS 2 139 242; DE-PS 2 064 641; AT-PS 146 213; FR-PS 427 582; US-PS 638 904 or DE-OS 3 135 700). To increase the functional reliability, a half-shell-shaped spoon can also be attached to the effective end of the ejection slide, which supports the transfer of the tobacco supply from the pressing chamber into the cigarette tube while at the same time maintaining its stability.

These known tamping devices have more or less proven themselves in practice. However, it suffers from the disadvantage that the acquisition costs for the initial equipment are relatively high due to the construction and mechanics for operating the ejection slide, which are quite complex in some cases, so that in this regard a certain inhibition threshold for the consumer has to be overcome. Furthermore, when filling the press chamber does not avoid a certain degree of contamination of the hands of the user and the surroundings with tobacco residues or crumbs, which is perceived as annoying in part and often prevents the user from using the same. Finally, manual filling means that the degree of filling of the press chamber and thus of the cigarette tube is not always the same. The cigarettes stuffed in this way are therefore characterized by different smoking behavior, namely different train, taste and differently long smoking time. In this respect, the self-filled cigarette behaves similarly to the self-rolled cigarette. The pollutant content of the self-stuffed or rolled cigarette in the conventional way is very different and uncontrolled according to the different filling levels of the cigarette tube.

From CA-PS 771 426 a device for transferring a tobacco supply from a cylindrical envelope into an auxiliary packaging is known, which should be usable in pipes. In this way, manual pipe plugging should be avoided. The cleaning of the pipes should also be made easier by simply removing the auxiliary packaging with the smoke residues.

To resolve the above shortcomings is both also suggested in the _DE -GM 8,326,921 as in DE-GM 8309186 a tobacco product for making home-made cigarettes by the consumer, which is in a fabrikatorisch by a not as such smokable prefabricated component in the form of Prefabricated tobacco cartridge consisting of an open-ended strand casing with the diameter of the cigarette paper sleeve of the finished cigarette and a strand-like tobacco filling, each corresponding to a cigarette portion, which can be transferred from the strand casing into an empty cigarette paper sleeve by an associated piston adapted to the inside diameter of the strand sleeve. This tobacco product is suitable for use in connection with conventional self-filling cigarette tubes as well as in connection with conventional self-rolling papers. According to the basic idea of this proposal to the consumer is an accurately measured, namely the capacity of a conventional, industrial consumer cigarette appropriate amount of tobacco in the form provided to a cigarette tobacco cartridge are available whose _T abakfüllung in a simple manner into a prefabricated cigarette tube commercially available type or a to a of Self-rolling cigarette paper sticky cigarette tube is transferable.

Although the latter proposal is a very considerable improvement over the prior art mentioned at the outset, it cannot be overlooked that the tobacco cartridge has a covering, namely a strand casing, made of non-smokable material. With regard to the end product "cigarette", the strand casing represents a superfluous one-time use Aids. Furthermore, in the latter proposal, further aids are required for transferring the pre-portioned tobacco supply from the strand sleeve into the cigarette paper sleeve, at least one ejection slide. The handling of the same without further aids for inserting the filled tobacco cartridge into the empty cigarette paper tube and holding the strand casing of the tobacco cartridge when transferring the tobacco supply should pose difficulties even for experienced in-house cigarette manufacturers.

The present invention is based on the object of improving the latter proposal in such a way that the tobacco product is only composed of smokable components with the exception of a possible filter and the self-manufacture of cigarettes from these components is also possible in principle without aids, such as ejection slides or the like is.

It is also an object of the invention to design the tobacco rod and to insert it into the cigarette paper tube in such a way that a tight fit is ensured therein and the use of conventional tamping devices is also possible.

This object is achieved according to the invention by the features mentioned in the patent claims (in detail and / or in the specified combination).

The invention, similar to the proposal according to DE-GM 8 309 186, creates a system for self-manufacturing of cigarettes by the consumer, which technically and economically optimally takes advantage of the highly developed, largely automated industrial cigarette manufacturing technology for the needs of the increasing number of self-rolling or self-tampering by supplying them with a preliminary product suitable for the problem-free completion of the cigarette by the consumer. Compared to the known solutions, the invention is further characterized by the fact that equipment aids for the in-house production of cigarettes are not absolutely necessary and that in particular the industrially prefabricated preliminary products, with the exception of the filter - if such a filter is provided or desired - are completely smokable, ie consist of smokable materials. The strand casings proposed according to patent claims 3 to 7 are also smoked in the assembled state. They are therefore no longer needed as disposable tools. It is also no longer necessary to transfer the tobacco supply from the strand casing into the cigarette paper casing, which definitely requires a certain skill, especially if suitable aids or devices are not available for this.

In addition, the effects of moisture on the tobacco supply no longer play a role in the invention when it is transferred to a prefabricated cigarette paper tube. The tobacco supply according to the invention always retains its original shape. If in the known systems the tobacco supply has become too dry due to storage, weather or climate, it cannot be compressed in a predetermined manner by transferring it from the strand casing into a prefabricated cigarette paper sleeve by means of an ejection slide, with the result that a so-called tobacco beard protrudes from the cigarette paper sleeve . On the other hand, if the tobacco supply is too moist, it is compressed too strongly by the ejection slide when it is transferred from the strand casing into the cigarette paper casing. The front end section the cigarette paper tube is then without tobacco. The goal of obtaining a cigarette corresponding to the industrially manufactured cigarette by in-house production has not been achieved.

Of particular interest is the embodiment according to claim 4, according to which the strand casing is formed by a porous and / or perforated, slotted or the like tobacco foil, which is also part of the tobacco supply. In this embodiment, the tobacco rod is made entirely of tobacco. Due to the porosity and / or the perforations, slits or the like provided in the tobacco foil serving as the casing, the tobacco rod as such is not smokable, although it is made entirely of smokable material. However, after inserting it into a cigarette paper tube or wrapping the tobacco rod with self-rolling cigarette paper, the tobacco rod becomes smokable. The effect of the porosity or perforations, slits or the like is lost due to the tightly fitting cigarette paper. The use of a tobacco film as a casing is also highly advantageous in terms of production technology, since the tobacco rod according to the invention can be produced in the manner of a cigarette on conventional cigarette machines, and above all very precisely in terms of the circular cross section adapted to the cigarette paper sleeve. Excellent diameter accuracy is achieved over the entire length of the tobacco rod. The tobacco rod corresponds in appearance to a stump or a corresponding cigar; only with the difference that the tobacco foil is air-permeable and in such a way that the tobacco rod as such is no longer smokable. A maximum air permeability of the outer strand casing is preferably provided strives. It only has to be ensured that the tobacco supply, which is in itself loose, is held together in a dimensionally stable manner by the strand casing. In extreme cases, the strand casing can therefore also be designed in the form of a net.

For passionate self-rolling people of cigarettes using cigarette papers, a filter piece of a conventional type can be attached to an end of the tobacco rod.

As already explained above, when a tobacco supply is provided in the form of a dimensionally stable, adapted to the tobacco filling of the finished cigarette and as such not smokable, but consisting entirely of smokable material, it is important that this tobacco rod is securely held in this in a prefabricated cigarette paper tube is, particularly with a tight fit on the inside of the cigarette paper tube. This is ensured by the measures according to claims 10 and 19, respectively.

The latter design of the tobacco rod is particularly suitable for conventional tamping devices for cigarette paper tubes with a press chamber in which the tobacco rod is compressed radially approximately to the inside diameter of the cigarette paper tube before being transferred into the cigarette paper tube. Compression is preferably carried out to an outer diameter of the tobacco rod which is slightly smaller than the inner diameter of the cigarette paper tube. Within the cigarette paper tube, the tobacco rod can then fill itself up with radial expansion, so that it is kept safe and smoke-appropriate.

Of particular note is the embodiment according to claim 14, according to which the tobacco receiving space of the cigarette paper tube has a greater length than the tobacco strand, namely preferably a length that corresponds to an integer multiple of the length of the tobacco rod. The cigarette paper tube is then filled by at least two tobacco rod sections each of approximately the same length. In this embodiment, the smoker can determine his consumption from the outset, ie to a predetermined fraction, e.g. B. half, by reducing the cigarette paper tube z. B. fills only with a tobacco rod section and the excess cigarette paper separates, preferably tears. If the consumer wants to smoke only a part of conventional cigarettes, the rest of the cigarettes are inevitably lost.

The tobacco rod can also have a greater length than the tobacco receiving space of the cigarette paper tube. The tobacco rod is preferably at least twice as long as the tobacco receiving space of a cigarette paper tube, so that at least two cigarette paper tubes can be pushed onto the tobacco rod and the tobacco rod can be separated at the joint of the two cigarette paper tubes. In this way, at least two cigarettes can be self-made at the same time.

To facilitate the introduction of the tobacco rod according to the invention into a prefabricated cigarette paper tube, a funnel-like tube is particularly suitable, which can be attached with its smaller diameter end to the front opening of the cigarette paper tube, the inside diameter of this end being approximately the same, preferably slightly smaller than the inside diameter of the cigarette paper tube. The insertion funnel represents a very simple device. A further relief is achieved in that the insertion funnel has at its smaller diameter end a cylindrical sleeve section which into the front opening of the cigarette paper sleeve can be used. The length of the cylindrical sleeve section is preferably such that the cigarette paper sleeve pushed over the sleeve section can be easily clamped between two fingers, preferably between the index finger and thumb, when the tobacco rod is inserted into the cigarette paper sleeve. This means that the length of the cylindrical sleeve section is approximately 10 mm should be. The outer lateral surface of the cylindrical sleeve section is preferably slightly tapered towards the free end or towards the end facing away from the funnel section, thereby facilitating the insertion of the sleeve section into the cigarette paper sleeve. In order to ensure a firm fit of the tobacco supply within the cigarette paper tube, the insertion funnel has a device that slits or tears open on the inside of the tobacco rod when it is inserted into the - cigarette paper tube along its jacket or the strand casing of the tobacco rod, in the form of one or more inside protruding knife, needle-like projections, or the like, can be formed. The loose tobacco supply will expand somewhat radially within the cigarette paper tube and be held securely within the cigarette paper tube.

The insertion funnel can also with a supply, preferably a capillary supply, for a wetting liquid, e.g. B. water, with a connection to the inside of the insertion funnel for the purpose of wetting the tobacco rod pushed through the insertion funnel. As a result, it experiences a certain "swelling" within the cigarette paper tube, causing it is also securely held within the cigarette paper tube.

For the purpose of facilitating the introduction of the tobacco rod into a prefabricated cigarette paper tube, the tobacco rod can be designed to be somewhat tapered at least at one of its end sections. Then an insertion funnel of the type described is even less required.

Finally, it should also be pointed out that the tobacco rod designed according to the invention can also be used without problems in conventional stuffing devices and self-turning devices. This is neither intended nor possible with tobacco cartridges with strand casings made of non-smokable material.

1 shows an industrially prefabricated dimensionally stable tobacco rod 10 in association with a likewise industrially prefabricated cigarette paper tube 11 with filter 12 of the conventional type used by self blockages. The main element of the system is the dimensionally stable tobacco rod igarettenpapierhülse outside the _Z 11 is unsmokable, but otherwise consists entirely of smokable material. In the exemplary embodiment shown in FIGS. 1 and 2, the tobacco rod 10 consists of a strand casing 13 made of thin tobacco foil material which is provided with perforations 14. According to FIG. 1, the perforations 14 extend over the entire length of the tobacco rod 10. The perforations 14 are preferably arranged approximately uniformly distributed over the length and the circumference of the tobacco rod 10. Instead of perforations, a porous tobacco film material can also be used as the strand casing 13. The strand casing 13 contains a strand-like tobacco filling 15 introduced by the manufacturer. The tobacco filling 15 in the strand casing 13 is packed approximately as tightly as in an industrially manufactured cigarette. The tobacco rod has a length which is approximately the length of the tobacco receiving space 16 of a commercially available cigarette paper tube 11 corresponds. The outer diameter of the tobacco rod is slightly, preferably about 1/20 - 3/10 mm smaller than the inner diameter of the cigarette paper tube 11, so that it can be inserted or inserted into the cigarette paper tube 11 without any problems. The tobacco filling 15 corresponds in terms of quantity to the tight packing of the cigarette tube 11 desired for the finished cigarette, specifically - as explained - in accordance with a normal factory-made cigarette. The cross section of the tobacco rod 10 is circular in shape to match the free cross section of the cigarette paper tube 11 over the entire length, so that it can be inserted into the cigarette paper tube without damaging the cigarette paper tube with full contact with the inside of the cigarette paper tube.

Instead of a tobacco foil material for forming the strand casing 13, porous and / or cigarette paper provided with perforations, slits or the like can be used. It is also conceivable to design the strand casing as a net or as an air-permeable film-like coating. It only has to be ensured that the strand casing consists of smokable material and is so permeable to air over the entire length that smoking the tobacco rod in the manner of a cigarette is not possible.

The system according to the invention is also suitable for use in connection with cigarette paper, in particular cigarette paper papers 17 as described by Self-turning is used in a conventional manner. This type of use is shown in FIG. 4, the same or corresponding parts being designated with the same reference numbers as in FIGS. 1 and 2. A cigarette paper sheet 17 of conventional type is wrapped around the tobacco rod 10 prefabricated according to the invention and glued as usual. The special feature of the embodiment according to FIG. 4 is that a filter piece 12 of conventional type is attached to the left-hand end of the tobacco rod 10 in FIG. 4 in such a way that the tobacco rod 10 and filter piece 12 represent a uniform preliminary product. This is wrapped with the cigarette papers 17 in total.

It can be seen that in the system according to the invention no strand casing remains as a disposable part. In this respect, the system according to the invention represents a significant advance over the previously known solutions with regard to material consumption and manufacturing and handling technology.

The self-manufacture of a cigarette with the aid of the system according to the invention using an insertion funnel, which is identified by reference number 18, is explained with reference to FIG. The insertion funnel 18 comprises a funnel section 19 and at its smaller diameter end 2 ₀ a cylindrical sleeve section 21 onto which the cigarette paper sleeve 11 is pushed. The length of the sleeve section 21 is about 8 to 12, preferably about 10 mm, so that the pushed-on cigarette paper sleeve 11 comfortably between two fingers, preferably index finger 22 and thumb 23, on the sleeve section 21 or insertion funnel 18 during the insertion of the tobacco rod 10 into the blank cigarette paper sleeve 11 can be clamped or held. The tobacco rod 10 is inserted into the cigarette paper tube 11 both in FIG. 1 and in FIG. 3 in the direction of the arrow "P".

As a special feature of the insertion funnel are the knife-like projections 24 on the inside of the cigarette or at the end of the cylindrical sleeve section 21 facing away from the funnel section 19, which slit the outer strand casing 13 of the prefabricated tobacco rod 10 through the insertion funnel 18 when it is inserted into the cigarette paper tube 11 that the tobacco supply 15 can expand radially outwards within the tobacco receiving space of the cigarette paper tube 11, as a result of which it is securely held in and / or snugly fitting against the cigarette paper tube 11. In the exemplary embodiment shown in FIG. 3, two diametrically arranged cutting knives 24 are provided. Basically, a single cutting knife is sufficient. Preferably, three cutting knives are provided, which are distributed approximately uniformly over the circumference and are each designed like a razor blade. Instead of the separating knife 24, needle-like projections can also be used to slit or tear open the strand casing 13. The separating device is also advantageous if the tobacco rod is held together by the tobacco fibers, which are inherently smokable binders, to form a dimensionally stable tobacco rod. A slight radial expansion of the tobacco rod within the cigarette paper tube is sufficient to ensure that it is securely held in the cigarette paper tube.

To facilitate the insertion of the insertion funnel 18 or sleeve section 21 at the front opening of the empty cigarette paper sleeve 11 is the outer The outer surface of the sleeve section 21 is preferably slightly tapered towards the free end. For the rest, the wall thickness of at least the cylindrical sleeve section 21 is minimal. It is approximately 0.15 to 0.3 mm. The dimensional stability of the sleeve section 21 is ensured by the circular cross-sectional shape and the connection to the funnel section 19, which preferably has a somewhat larger wall thickness. The insertion funnel 18 can be made of stainless steel sheet or plastic. The inside transition between the cylindrical sleeve section 21 and the funnel section 19 (in the region of the smaller-diameter end 20 of the funnel section 19) is rounded off, so that the tobacco rod 10 can be easily inserted into the cigarette paper sleeve 11 through the insertion funnel 18. In the area of the smaller-diameter end 20 of the funnel section 19 or in the area of the connection of the cylindrical sleeve section 21 to the funnel section 19, an outer ring flange 25 is provided which serves as a stop for the cigarette paper sleeve 11 pushed over the sleeve section 21.

FIG. 5 shows an industrially prefabricated, dimensionally stable tobacco rod 10 in association with an also industrially prefabricated cigarette paper tube 11 with filter 12 corresponding to FIG. 1. In the exemplary embodiment shown in FIG. 5, the tobacco rod 10 is only intended to exist as tobacco fibers that are more conventional due to a binder Kind are held together to a dimensionally stable tobacco stick. The outside diameter of the tobacco rod is chosen to be somewhat larger than the inside diameter of the cigarette paper tube 11, preferably about 5 to 10% larger, so that it can be transferred into the cigarette paper tube 11 with radial compression. To for this purpose, the tobacco rod is placed in a pressing chamber 26 of a conventional stuffing device for cigarette paper tubes, compressed in the radial direction in this, ie brought to an outer diameter which is preferably somewhat smaller than the inner diameter of the cigarette paper tube 11. Then the tobacco rod compressed in this way is by means of a piston-like Ejection slide 29 is transferred into the cigarette paper tube 11 attached to the open end face of the pressing chamber 26. In Fig. 5 only part of the tamping device is shown very schematically, since this is a device known per se. For this purpose, reference is made to DE-PS 2 139 242 or DE-PS 2 064 641 or DE-OS 2 833 681 only by way of example. The pressing chamber 26 according to FIG. 5 is thus defined in a manner known per se by a first half-shell 27 fixed to the housing and an associated pressing bar 28 which forms a second half-shell and which can be moved back and forth in the direction of arrow “K” in the housing of the stuffing device, not shown is stored.

Solutions are also conceivable within the scope of the invention in which the tobacco rod is longitudinally divided, the cross section of each part corresponding to a preferably straight part of the cross section of the cigarette paper tube. The tobacco rod can be composed of two rod halves, three or more rod segments or rod sleeves pushed into one another. Two, three or more strand parts must then be used in a corresponding manner to fill the cigarette paper tube.

It is equally grateful that the cross section of the tobacco rod corresponds to a multiple of the cross section of the cigarette paper tube, e.g. B. twice, in which case the tobacco rod is preferably the Cross section of an "8" has. Before use wit ° the tobacco rod is broken apart along a connecting web or the like, so that two individual tobacco strands are formed, each of which is used to fill a cigarette paper tube, but is better wrapped with a cigarette paper sheet because of the burr that may arise. It is equally conceivable that the tobacco rod comprises three or more individual tobacco rods, which are arranged in a star shape or around a central tobacco rod.

In principle, it is also conceivable that the tobacco rod (10) has a cross section in the form of a polygon, in particular triangle, quadrangle, hexagon, or in the form of an oval, trapezoid or the like, preferably in such a way that the tobacco rod thus formed has a cross section of Cigarette sleeve can be brought substantially uniformly filling cross section, in particular compressible (z. B. in the press chamber 26 of FIG. 5).
