Abstract

The system comprises a tobacco filling encased in a wrapping matching the tobacco portion for insertion into the interior of the filter cigarette paper sleeve. An implement in the form of a thin, rigid metal or plastics tube with two ends has the tobacco portion packet inserted through one end. The cigarette paper sleeve is placed over it from the other end. After the portion-packet has been inserted into the transfer tube, the wrapping is removed. The tobacco filling removed from its wrapping is inserted through a piston guided in the rigid tube and inserted into the cigarette interior of the filter cigarette paper sleeve slid over the transfer pipe.

Description

The invention relates to an industrially manufactured prefabricated product for use in the Self-production of cigarettes by the consumer of claim 1 specified genus and a system for self-production of cigarettes by the consumer using such an industrially manufactured prefabricated product.

Various systems have become known in recent years, in which the consumer is a non-smokable as such Prefabricated product in the form of a prefabricated, encased or encased tobacco rod provided was made to make it easier to make cigarettes compared to the usual conventional forms of self-turning or self-stuffing. For tax reasons thereby (at least functional) non-smokability of the prefabricated product required. With most of these known systems the prefabricated, wrapped tobacco rod ('cigarette tobacco cartridge') into the one used to finish the cigarette (Filter) cigarette paper sleeve of the usual type in axial Direction introduced and inserted.

One from the European patent specification 0 123 150 (LIEBICH) known basic form of such a system is for the sake of example illustrated in Figure 11 of the present application drawing. In mutual assignment it shows the whole at 61 designated tobacco cartridge from tobacco rod or fill 63 and Strand casing or casing 62, the associated filter cigarette paper casing 64, 65 and a sliding piston 66. Die Non-smoking of the prefabricated product (tobacco cartridge) was 61 by a perforation 68 in the strand casing and / or by a corresponding one Material of the strand casing 62 guaranteed. For The tobacco cartridge 61 was first manufactured inserted into the tobacco receiving space 64 of the cigarette paper tube, then he was freehand from the free forehead guided transfer piston 66 inserted into the strand casing 62 and holding the strand casing by pressing the end of the strand casing against the surface of the transfer piston 66 the tobacco rod or the tobacco filling 63 from the strand casing 62 ejected, with gradual removal of the gradually filling cigarette tube. For easier insertion of the piston and its guidance during the initial phase the transfer process could end at one end of the tobacco cartridge tobacco-free section 67 may be provided within the strand casing 62. Beneficial at This system is that the finished cigarette thus obtained with regard to the material The nature of its components and the smoking behavior of a conventional one corresponds to the finished industrial cigarette. However, for the transfer of the tobacco filling from the skein into the cigarette paper tube with the help of the free-hand piston some manual dexterity and practice is required. The flyover of the tobacco rod takes place against the frictional resistance on the casing; the tobacco rod is strongly slowed down by the tight-fitting cover can result in the tobacco rod not sliding smoothly Sections compressed or too loose over the entire length of the filter sleeve the tobacco filling, it can lead to strong tobacco densifications, which in extreme cases can lead to the sheathing of the casing and the filter sleeve. As a result of fluctuations in the degree of compaction of the transferred tobacco rod the transferred tobacco does not cut off smoothly with the end of the filter sleeve, this means that either a certain empty space remains at the end of the filter sleeve or tobacco protrudes beyond the end of the filter sleeve. There is a certain disadvantage also the basic requirement of axially inserting the cigarette tobacco cartridge into the cigarette paper tube; with this system there is an extremely exact fit tolerance between Tobacco cartridge and cigarette paper tube not indispensable. In the interest of a full Filling and placing the tobacco filling on the cigarette paper tube without any noteworthy Compression of the tobacco filling during the transfer process is a relative one close adjustment between the outside diameter of the tobacco cartridge and Inside diameter to prefer the cigarette paper tube, which on the one hand appropriate dimensional accuracy and tighter tolerances when Manufacturing process conditional and on the other hand the introduction of Tobacco cartridge in the cigarette paper tube can complicate.

These complications are much more critical in the case of the European patents 0 155 514 (EFKA) and 0 178 605 (LIEBICH) known system of the so-called 'stick cigarette'; here the strand casing of the tobacco cartridge consists of a flammable and smokable material, it remains in the finished Cigarette and is smoked. The non-smokability of the The cartridge must only be made of a correspondingly porous one or perforated formation of the strand sleeve ensured be, the smokability of the finished cigarette by Closure of this porosity or perforation of the strand casing through the cigarette paper tube when inserted should be guaranteed. This requires an extremely tight Fit between tobacco cartridge and cigarette paper tube, with correspondingly narrow, critical relative manufacturing tolerances between cigarette paper tube and tobacco cartridge; on the other hand this is the introduction of the tobacco cartridge particularly difficult, especially when - about the total paper content to keep as low as possible - the outer cigarette paper tube from a particularly thin cigarette paper will be produced. In practice you take a compromise between a tight fit and the practicality of introducing the Cartridge into the cigarette paper tube in purchase, so did this increased secondary air problems result, which Smoking behavior of such a cigarette compared to one customary finished consumer cigarette clearly differs. This disadvantage is exacerbated by the fact that this System by the total increased paper content of the finished Cigarette (the cigarette case remaining in the cigarette has to be smoked) the smoking behavior and the taste of the Cigarette are significantly changed from the usual.

In the (not prepublished) German patent application P 44 04 274.4 proposes the wrapped tobacco strands first insert into a tube in a device, and the Then fill the tobacco in the axial direction from the casing by a piston into a coaxially aligned with the first tube to assign assigned cigarette tube holder tube, from which the tobacco filling by further piston feed in cigarette paper tubes drawn onto the cigarette tube holder is transferred. The direct insertion of the wrapped Strands of tobacco in the cigarette paper tube are avoided here, and the final transfer of the tobacco rod takes place after removing the strand casing from a metal tube with only minimal friction of the tobacco filling on the inner wall of the Tobacco pipe. However, the initial introduction of the wrapped portion of tobacco in a tube and the subsequent Transfer to a sleeve support tube complicating both the Cigarette manufacturing process as such as well certain complexity and size of the necessary Contraption. In this (not pre-published) German Patent application P 44 04 274 is already an industrial one Prefabricated product proposed, in which two or more tobacco serving units in the form of coated with a strand casing Cigarette tobacco rods through lanyards to one Multi-portion packaging are combined, making the immediate Introduction of a portion of tobacco in the cigarette room Cigarette paper tube is impossible, so the use of the Single portion in the sense of the mentioned 'stick cigarettes' excluded is.

From European patent specification 0 178 605 (LIEBICH), Fig. 12 a system is known in which the strand casing of the prefabricated, coated or coated tobacco rod with a from the closed circumference radially protruding grip tab as well is designed with an axial predetermined tear point; as assigned Equipment is one along part of its length a slotted tube made of a resilient-flexible Material provided, in the slot of a trapped in the tube Short piston is guided longitudinally; for self-production the wrapped tobacco rod becomes the cigarette in the slotted tube inserted so that the trigger tab laterally protrudes through the slot; then pull the tab under the side Breakage of the predetermined tear seam pulled the strand casing laterally out of the slotted tube; then a cigarette paper tube is drawn onto the outside of the slotted tube, and finally the tobacco rod, which has been freed from the casing, through the short piston into the Transfer tobacco receiving space of the cigarette paper tube, under successive Push the cigarette paper tube off the tube. The combination of one resiliently flexible tube with a short piston guided in it along a slot has proven to be less than optimal.

A further development of the industrially manufactured prefabricated product according to EP-A-0 123 150 is described in DE-A-3 914 669, the tobacco cartridge and the piston during the transfer of the tobacco filling of the tobacco cartridge into the sleeve section a cigarette paper tube is held and guided through a surrounding tube become. The preamble of claim 1 goes from this industrially manufactured Prefabricated product.

By the present invention, an industrially manufactured prefabricated product in Preamble of claim 1 specified genus and a system for Self-manufacturing of cigarettes using such a prefabricated product be proposed in which the imperfections and intolerances of the known systems are avoided and in a simple process and by means of a simple equipment with a small footprint, the manufacture is complete evenly filled cigarettes with no special manual dexterity or practice is possible

This is achieved by the features of claims 1 and 12, respectively.

The features of the subclaims provide expedient configurations Are defined.

The self-production of a cigarette using the system according to the invention is free of the imperfections or intolerances of the known systems; it is completely simple, does not require anything special manual dexterity or practice and results in a cigarette regarding the Uniformity of the degree of filling, external appearance and especially in their Smoking behavior completely of a usual industrially manufactured cigarette corresponds. To manufacture the cigarette, the user only needs the as Industrial prefabricated product provided wrapped tobacco portion packaging in to insert the transfer tube, to free it from the strand casing, one Pull the filter cigarette paper sleeve onto the outside of the transfer tube and then by simply pushing the long piston through the transfer tube the tobacco rod exposed in the transfer tube into the cigarette paper tube convict. Since in the system according to the invention, the strand casing is removed Portion of tobacco from the transfer tube directly into the gradually filling filter sleeve is transferred, the sliding takes place exclusively between the tobacco filling and the smooth inner wall of the transfer tube instead, so that no larger and in particular fluctuating frictional resistances are to be overcome and none relative Compression or congestion can occur, especially since filter cigarette paper tube pushed onto the transfer tube successively with the transfer of the tobacco portion from the also smooth outer wall of the transfer tube without scrapes off any noteworthy friction or braking. Through this unobstructed way of transferring the tobacco portion is a completely even filling of the cigarette guaranteed over its entire axial length, whereby after the Completion of the tobacco rod transfer process as in a manufactured cigarette with the end of the Cut the filter sleeve smooth.

The smoothness of the transfer process is particularly also by using one from the other end of the transfer tube long piston introduced, which of Start of the transfer process in the tobacco-free section the transfer tube is guided and in the further Feed in the transfer tube in the course of the transfer process still reliably guided in the transfer tube remains.

The equipment required for the system according to the invention has an extremely simple, easy to manufacture and in the Use of a structure that is not susceptible to faults with very small dimensions, barely bigger than a disposable lighter, like that that the equipment can be easily used by the user can be carried.

According to preferred embodiments, the equipment can be a also used to hold the device elongated housing base have, at one end the transfer tube is held and fastened so that a first, for Inclusion of the filter cigarette paper sleeve certain end section the transfer tube from the mounting point cantilevered along the elongated housing base in one extends slightly above this. According to one a particularly advantageous embodiment provides that the elongated housing base body in the axial direction over the cantilevered end of this first end portion of the transfer tube extends beyond such that at the end of the transfer operation the finished cigarette is supported and not needs to be caught especially.

The transfer tube can also in other configurations a second, in the opposite direction to the first end section protruding end portion from the bracket have, which serves to hold the tobacco portion pack and optionally slotted, with the tobacco filling using of the piston from the second end section into the actual Transfer section forming the first end section and into the Filter cigarette paper tube can be transferred. At this Embodiment are the filter cigarette paper tube and the tobacco portion pack from opposite sides or pushed into the transfer tube. The first end section can be unslotted in this case.

Here, the second end section can not only be slotted but only as an open trough with an approximately semicircular shape Cross-section into which the tobacco portion package is only inserted. This is particularly useful if a variety of tobacco portion packs on is attached to a belt-shaped carrier.

In embodiments in which at least one end portion the transfer tube is slotted and the strand casing in front the transfer of the tobacco portion into the filter cigarette paper tube can still be removed be that a knife element, for example, by a Slit in the transfer tube radially in the interior extends, this knife-shaped element when inserted the tobacco portion package slits the strand casing so that it is easy to pull out. In this case, the target tear point the strand casing is eliminated.

The non-smokability of the industrially prefabricated tobacco portion packs, as for tax preferential treatment may be required in several ways, if necessary also cumulative, can be guaranteed: that for the wrapping of the As such, tobacco rod material used can be unusable or be non-flammable; the optional axial The predetermined tear point of the strand casing can be useful as a perforation be carried out, whereby an independent smoking of the enveloped Portion of tobacco is excluded; according to an advantageous Embodiment can be provided that the strand casing the tobacco portion pack on its outside with a preferably strip or line material application a smoking impairment, but harmful to health Provide material (for example a bitter tea) is; the portion pack can be of a smaller diameter formed as the inside diameter of the transfer tube be such that when (improper) insertion of the encased tobacco portion packaging immediately in a cigarette paper tube a secondary airway that prevents normal smoking would exist; alternatively, the portion pack could also slightly larger in diameter than the inside diameter of the Be filter sleeve so that it is not for direct smoking can be inserted into a filter sleeve. By an appropriate Greater length or thickness of the tobacco portion pack based on the filter cigarette tube ensures that it is completely filled.

According to an advantageous embodiment, it can be provided that the tobacco portion package as a double or two-portion package of two parallel spaced apart, individual portions connected by a connecting part is educated. Here, the connecting part prevents in addition, the immediate introduction of the individual Portions of tobacco in a cigarette paper tube.

In all embodiments, it can also be provided that that the length of a tobacco portion package is essentially an integral part of the length of the filter cigarette tube corresponds, so that only the transfer of the tobacco fillings several tobacco portion packs in the filter cigarette paper tube completely fills them. Here the tobacco strands a corresponding number of tobacco portion packs successively transferred to a filter cigarette paper tube to to fill them completely. The shorter length of the tobacco portion packs further facilitates the transfer process into the filter cigarette tube.

Overall, the system according to the invention gives an optimal one Solving the problem of self-made cigarettes the consumer using industrially prefabricated Portion packs of tobacco.

First, an essential part of the invention Systems forming device described in the 1 to 3, which shows the device in side view (Fig. 1), in plan view (Fig. 2) and one part show the device forming transfer piston (Fig. 3). The device designated as a whole by 1 has a for Bracket serving housing 2 on; this is a total roughly prismatic elongated body 2, which is on its top with one extending essentially over the entire length Longitudinal trough 4 is provided. On the one hand (in the drawing left) end of the housing body 2 is in the Trough a mounting ring 3 attached, for example by Gluing. In the mounting ring 3 is - as an essential part the device according to the invention - a relatively rigid, thin-walled transfer tube 5 made of metal or plastic embedded (in the following only refer to a metal pipe is taken, although both materials and other materials, such as wood, if appropriate, use can find), which is parallel to the trough part 4 extends and fully penetrates the mounting ring 3 and at its outer (left in the drawing) end face 6 opens openly. The Transfer tube 5 is in the mounting ring 3 over its entire Axial extension embedded and thereby firmly anchored; on the end face 7 opposite the outer end face 6 the mounting ring 3, the tube 5 is cantilevered with his Main length over and extends parallel to the trough 4 of the Housing body 2, with which the transfer tube 5 along its projecting, unsupported length is aligned. The Relative arrangement of transfer tube 5 and housing body 2 with Longitudinal trough 4 is such that over the self-supporting Length of the transfer tube 5 between which the trough 4 facing Underside and the trough surface adapted to the pipe bend a distance which is essentially constant over the length d (from approx. 2 to 3 mm, compare the cross-sectional views of Fig. 4) remains in the embodiment shown practically corresponds to the material thickness of the mounting ring 3.

The axial extent of the housing 2 is somewhat larger than that of the tube 5, such that the housing body 2 at its the Bracket ring 3 opposite end 9 in the axial direction about the free end 10 of the transfer tube 5 by about 1 protrudes up to 2 cm.

According to an essential feature of a preferred embodiment the transfer tube 5 of the device according to the invention is on its top with an axial longitudinal slot 11, the over the entire unsupported length of the transfer tube 5 extends (and possibly also in the in the mounting ring 3 Continue the recessed end of the transfer tube 5 may be preferable if this is for manufacturing reasons is). The slot 11 preferably has a width of approximately 1 mm. The transfer tube 5 is at its free end 5A 12 (in side view) beveled and at 13 (top view in Fig. 2) rounded at the transition to the slot 11, for Facilitate the introduction of (described below) Tobacco portion packaging and to facilitate (also pushing on the cigarette paper sleeve described below, when using the device for self-made Cigarette. This is near the mouth of the slot 11 provided with a nose 14, the function of which in the below following functional description of the device is still explained.

Another essential feature of the device according to the invention is the sliding or transfer piston shown in Fig. 3, which is designated as a whole by 15. The piston is there mainly a cylindrical one that takes up the main length Piston part 16 and is at one end with a Provided flange part 17 of larger diameter, that as an actuator and serves as a stop. When using the device the piston 15 with its piston section 16 in the at outer end face 6 opening opening of the tube 5 is introduced (as indicated by arrow I) and successively into the pipe advanced to the transfer of the Portion of tobacco from the tube 5 in the cigarette receiving room Cigarette paper tube. The piston is until the system Stop flange 17 on the end face 6 of the mounting ring 3 pushed through. This is the transfer of the tobacco portion completed. The piston is removed from the tube when not in use pulled out and from the opposite side according to the Arrow II inserted into the free end 12 of the guide tube 5. As soon as the actuation and stop button 17 in the Area of the trough 4 arrives by a slight Jamming a self-locking of the piston in its Storage position reached in the device.

The housing 2 and the piston 15 can be made of any enough dimensionally stable material has to be produced, especially made of plastic. In this case, the housing and the piston is easily produced as injection molded parts become. Alternatively, the housing and / or piston also be made of wood.

The tube 5 should have a high dimensional stability and torsional strength with the smallest possible wall thickness. Therefore, the manufacture of metal is provided for the tube 5, for example of stainless steel or hard brass. The wall thickness can be on the order of 0.2 to 0.3 mm. The outside diameter of the tube can, for example, be 6.8 mm in coordination with the inside diameter of the cigarette paper tube that has to be pulled onto the tube.
The transfer tube 5 can be made, for example, from drawn seamless tube material with subsequent longitudinal slitting; alternatively and preferably it can be rolled from the corresponding sheet; in this case, the slot 11 then extends over the entire length of the transfer tube 5, ie also in the section let into the holding ring 3. It is essential for the functionality that the inside (and outside) surface of the metal pipe is as smooth as possible, in order to ensure that the tobacco portion on the inside can be pushed out freely and smoothly (and that the cigarette paper tube is pushed on and stripped off just as smoothly on the outside of the pipe).

The axial extension of the device is ultimately due to the Length of the industrially prefabricated tobacco portion packaging and this due to the usual length of the cigarette receiving space determined a filter cigarette paper tube. The total length of the piston can be approx. 11 cm, its usable piston length, which is approximately the unsupported length of the transfer tube 5 corresponds, can be approx. 95 mm. Total results this for the device (which is essentially in the drawing is shown in natural size) a total length in of the order of 12 to 13 cm, with a width in of the order of approx. 2 cm (top view) and a height (in side view) of about 2 cm. As can be seen This results in extremely small overall dimensions of the device according to the invention, which is hardly larger than a disposable lighter is and if necessary by the user without further notice can be carried if he does not prefabricate one Larger number of cigarettes according to the respective Prefers daily requirements.

The following is the other essential component of the invention Cigarette self-manufacturing system described namely the industrially prefabricated tobacco portion packaging, of which in FIGS. 5 and 6 two embodiments in Cross-sectional view in section perpendicular to the longitudinal axis are shown. The tobacco portion package, designated as a whole by 20 consists of the inner tobacco rod 21 and one this enclosing strand casing or casing 22. At 23 is an axially parallel predetermined tear point provided according to the invention, for example in the form of a longitudinal perforation or other weakening seam, provided. According to the invention the strand casing with one projecting outward from the circumference Trigger tab 24 provided. In the embodiment shown in FIG. 5 is the trigger tab 24 in terms of manufacture as a separate Executed part by a indicated at 25, relatively wide area bonding relatively high tensile strength is glued to a peripheral region of the strand casing 22, which is at some distance from the predetermined tear perforation 23.

According to a particularly advantageous embodiment, provision can be made be that the trigger tab 24 at its free end 26th provided by the manufacturer with a pressure sensitive adhesive application 27 and in the direction of arrow 28 in the position shown in dashed lines folded over the circumference of the portion packaging and with the strand casing at 26, 27 is glued easily detachable. This will achieved that the trigger tab manufacturer's machine Handling and packaging not hindered, but on the casing is present while it is intended for later use Easily used by the user at their free end 26 can be detached from the casing 22 and for the peeling process is available. The pressure sensitive adhesive seam 27 should therefore only be a minor one Have adhesive strength.

At 29 is a material application applied in a longitudinal track indicated that the (improper) attempt of the Burning or smoking the coated tobacco portion as such would affect smoking. This represents one additional measure represents the non-wearability of the industrial prefabricated coated tobacco portion as such ensure, in addition to the other measures mentioned (possible Uselessness of the strand casing material; porous formation of the Extruded casing material, perforation of the extruded casing and, if appropriate a little too small or a little too big diameter of the Portion packaging, based on the inner diameter of the filter cigarette paper tube). The order 29 should be made of one material exist, that the (improper) burning the Smoking would spoil, but harmless to health is and also with longer storage of the pre-made tobacco portions smell of the tobacco rod or otherwise impaired. This material order can for example a bitter tea in a suitable carrier act.

6 is a modified embodiment of the industrial prefabricated tobacco portion packaging shown. Same or corresponding parts have the same reference numerals as in Fig. 5 designated. The main difference from the embodiment 5 is that the trigger tab 24A is integrally formed here with the casing 22 and simple an extension of the strand casing over the bond area 25A in which the two strand ends are glued together. At 23 is again the target tear point the jacket and at 29 the material order Impairment of smoking pleasure with (improper) Wear of the prefabricated product as such is visible.

Fig. 7 shows a perspective view in a schematic representation a prefabricated tobacco portion package of the described Art. At 23A is about half the length of the portion package a further predetermined tear point 23A is provided, which runs in a plane perpendicular to the strand axis and itself over the entire circumference of the strand casing 22 the trigger tab 24 extends. This transverse breaking point 23A can expediently be designed as a perforation again. This will remove the sheath at the next Intended use of the tobacco portion packaging described below facilitated in the device according to the invention. Through this cross perforation 23A the division the strand casing 22 into two axial sections 22A, 22B approximately half length allows, the side deduction by the Slit of the transfer tube 5 of the device even easier and is easier to do than pulling off the strand casing 22 along its entire length in a single act.

The following is the self-made cigarette by the consumer from the above with reference to FIGS. 5 to 7 described prefabricated cigarette tobacco portion packaging with the help of the invention described in FIGS. 1 to 4 Device explained. Another element occurs for the manufacture of the cigarette a conventional filter cigarette paper tube, as illustrated in FIG. 8. The sleeve designated as a whole by 30 has the actual sleeve section 31 and consisting of conventional cigarette paper a filter section 32 attached to it. For the production The finished cigarette is proceeded as follows: First, the sliding piston 15 from its (assumed) storage position pulled out in the transfer tube 5 (against the Direction of arrow II in Fig. 2). Then the wrapped Tobacco portion 20 (or 20A) after its pull tab 24 (24A) at the free end 26, lifting the weak PSA 27 detached from the circumference of the strand casing 22 and into the full in Fig. 5 solid actuated position shown laterally was brought into the transfer tube 5, namely so that the laterally protruding pull tab 24 (24A) through the Slit 11 protrudes outwards. During this insertion process Portion packaging in the slot 11 causes the above-mentioned provided in the initial region of the slot 14 Wiping off excessly applied adhesive 25, such that a clear lifting of the tab 24 from the circumference of the strand casing comes along a straight line. The tobacco portion pack 20 is fully inserted into the transfer tube 5 i.e. until the portion pack stops with your inner end against the end wall 7 of the mounting ring 3 of the Contraption. Now by pulling on the tab 24 (24A) the wrapping of the portion package at a predetermined tear point longitudinal perforation 23 torn open and after subtracted outside. As above with reference to FIG. 7 already mentioned, this process of peeling off the strand casing significantly facilitated by the transverse perforation 23A become. This allows the strand casing to be practically in two Divide halves 22A, 22B, which are easier to separate separately can be peeled off as the strand casing over the entire Length as a whole.

As a result, the tobacco portion is now freed from the casing, in the smooth-walled transfer tube 5 before, for transfer into the cigarette paper tube, as the last step of the Manufacturing process.

For this purpose, the filter sleeve 30 (FIG. 8) with its Sleeve section 31 pushed onto the outside of the tube 5 or raised. Due to the slight gap d (Fig. 4) between the outer wall of the tube 5 and the trough 4 becomes a certain Linear guidance of the filter sleeve when plugged onto the tube 5 ensures and a deformation of the thin paper Filter sleeve avoided. The filter sleeve 30 is as far as it will go pushed onto the transfer tube 5, i.e. by Stop the filter section 32 against the outer free end 12 of the transfer tube 5. Now the opposite Side (end face 6 of the mounting ring 3) of the housing the sliding piston 15, 16 inserted (in the direction of arrow I) and pushed to the end of the flange 17 on the end face 6. Since the tobacco only against the smooth inner surface of the Tube 5 rests, the tobacco slides at low piston pressure lightly and evenly into the filter sleeve, this gradually is just as easily stripped from the smooth outer tube. At the end of the transfer process, the tobacco rod cuts, like a factory cigarette, with the end of the filter sleeve clean off. It is particularly advantageous that the certain protrusion of the housing body 2 over the pipe end 10 of the Tube 5 the nascent cigarette during the last stage is supported and therefore no longer against Falling needs to be caught. The handling of the Device is extremely simple. During the transfer process the device is held with one hand on the housing 2 while the other hand pushes the piston 15, 17 through the tube 5.

Since in the system according to the invention already from the strand casing Exempted portion of tobacco from the (smooth-walled) transfer tube 5 directly into the successively filling filter sleeve is transferred, the sliding takes place exclusively between the tobacco filling and the smooth inner wall of the transfer pipe instead, so that no major and in particular fluctuating Frictional resistances are to be overcome and not relative Compression or congestion can occur; thus a completely even filling over the entire length of the cigarette reached without internal empty or hollow sections or compression and stowage sections with corresponding Strain on the cigarette paper sleeve in known Executions until the sleeve could tear.

According to a particularly advantageous embodiment of the invention can use the industrially prefabricated tobacco portion pack several, preferably two portions of tobacco joined together exhibit. Such an embodiment is in Fig. 9, which shows such a double-portion package at an intermediate stage of processing in a correspondingly adapted two-channel version of the device shows, in cross section corresponding to one to the longitudinal direction portions of tobacco and transfer pipes of the device rectangular plane. The one designated as a whole at 40 Double or two-portion packaging consists of two single portions 41 and 42, in the example shown, like that Portion packs designed according to the embodiment of FIG. 5 are, but correspond just as well to the design of FIG. 6 can. The individual portions 41, 42 are by a connecting part 43 connected with each other, which is the matter those connected at their free ends or in one piece trained side pull tabs 24 (Fig.5) of the individual portions acts. At 44 is in the central area of the connecting part 43 a predetermined tear point 44 running in the longitudinal direction provided by means of which the connecting part 43 is separated and the two individual portion packs 41, 42 are separated from one another can be. 9 is the preferred processing such a double tobacco portion pack in one The device illustrates which of those in FIGS. 1 to 4 device shown and described corresponds, however is adapted as a two-channel device, i.e. that they each side by side on the top of the common housing body 2A two parallel troughs 4A and two by means of Bracket rings 3A has slotted tubes 5A. For Processing the double pack in such a two-channel device can the double pack 40 conveniently in the undivided Condition in the two parallel slotted tubes through the one in question Slits 11A are inserted, whereupon the connecting portion 43 is separated along the predetermined tear point 44, what by simply lifting it, for example using the one below guided piston rod can happen. Here then form the two half sections of the connecting part 43 the side Trigger tabs 24A with their free ends to the side Peeling off the strand casings can be used. Alternatively could the separation of the double package 40 by separation the predetermined tear 44 also take place before insertion, and the then separate single-portion packs as described above be inserted into the two tubes 5A. After the side Pull off the casing and pull up one cigarette paper sleeve each 30,31 on the respective slotted tube 5A then the transfer of the tobacco portions into the cigarette paper tubes by means of the piston 15 (Fig. 3). According to a preferred Embodiment can provide a double piston unit be made of two pistons 15, 16 parallel to one another 3 may exist which, for example, on each other Actuating end 17 to be connected at the predetermined distance can. Alternatively, the transfer can also be carried out using two separate single pistons are made either simultaneously be pushed through or in time.

The advantageous multiple, especially double-portion packaging of the two-pack 40 in Fig. 9 can of course also in a simple single-channel device according to FIGS. 1 to 3 are processed, either simply after previous separation of the double portion packaging along the Desired tear point 44 as single-portion packs according to FIG. 5 or 6, or alternatively without prior separation, such that first a single serving, for example the serving 41, is inserted into the slotted tube, namely by means of connecting tab 43 obtained first without separation, then the Strand casing of this introduced tobacco portion pulled out to the side is processed and processed until the finished cigarette while the remaining tobacco portion 42 of the double pack then next inserted into the single channel device and processed.

The training of the industrial prefabrication as multiple tobacco portion packaging also has the further advantage that hereby an additional safeguard against an (improper) Use of the industrial prefabricated product in the known from the aforementioned patents as "Sticky cigarette" is given what is the desired tax Recognition for the favorable fine cut tariff of the tobacco tax supported.

For the assembly of industrially prefabricated Tobacco portion packs of the system according to the invention exist various possibilities. So the single portion packs 5 or 6, in particular in the preferred embodiment shown with the manufacturer pull tab folded over to the circumference of the casing, in a similar way to normal industrial cigarettes be assembled. Similarly, double portion packs could similar to the type of pack 40 in FIG. 9 according to the type of conventional cigarettes in corresponding Packs (cigarette boxes) are made up.

According to an advantageous embodiment, it can be provided a larger number of individual portions for packaging to be arranged on a common carrier. Such Design is illustrated in Fig. 10. As can be seen are in this form in the form of a whole with 50 designated assembly unit a larger number of Single portion packs, for example 10 single portions, on a common belt or band-shaped carrier 52 to one Packaging and packaging unit 50 summarized. The Individual portions 51 can be of the type shown in FIG. 5 or 6 Be of a type and are only indicated schematically in FIG. 10, the trigger tabs 24 and 24A (from FIGS. 5 and 6) in FIG. 10 are omitted for the sake of clarity. As can be seen the individual portions 51 on the carrier belt 52 are parallel to each other by means of bonds 53 indicated at 53 temporarily attached. The arrangement can be such that the Carrier belt 52 folds approximately in the middle at 54 (and if necessary separable) is formed such that the two so formed Belt halves by folding (in Fig. 10 by arrow 55 indicated) with their backs against each other become. In this form, this multi-portion packaging then be packaged, for example in packaging similar to an ordinary pack of cigarettes, or possibly also in a large pack with a round cross-section.

According to an advantageous embodiment, the multiple portion packaging 10 not only as a packaging and packaging unit provided but also as Processing unit to be trained, analog and in training that illustrated in Fig. 9 and described above Two or two packs. For example, the Multi-pack shown in Fig. 10 formed as a six-pack with three individual portions 51 on each of the two connected by the fold or kink 54 Leg of the belt-like carrier 52. Processing a such a multiple pack could be in a corresponding Multi-channel version of the device analogous to the two-channel version in FIG. 9. For example, in the three individual portions of a three-channel device 51 can be processed on each of the two belt legs, whereby the belt 52 performs the function of the connecting part 43 in FIG. 9 takes over, that means for insertion and serve as a pull tab can. Alternatively, of course, one could Six-pack also in a simple single-channel device Figures 1 to 4 are processed, each successively the individual portions of the multiple pack in the device can be introduced.

The invention has been described above on the basis of preferred embodiments described, but of course in manifold Details can be modified and therefore should not have any restrictive meaning. For example in the device instead of that in FIGS. 1 and 2 shown simple bracket of the slotted transfer tube 5 by means of a mounting ring to be glued into the trough 4 3 other types of cantilevered mounting of the slotted transfer tubes 5 over and in alignment with the trough 4 of the housing body 2 can be provided. For example could, as shown in the cross-sectional view of FIG. 4B, at the position corresponding to the mounting ring 3 solid block 3 B provided be in which the transfer tube 5 with its anchoring end would be let in and in any way, for example by gluing or preferably also in one piece Training could be connected to the housing body 2. Accordingly exist for the industrially prefabricated Tobacco portion packs in addition to those in FIGS. 5 and 6 other embodiments shown by way of example Modifications, especially with regard to the Training and attachment of the pull tabs for the side Pull it off.

Furthermore, a predetermined tear or perforation 22 is the Filter cigarette paper tube 22 as shown in FIGS. 5 and 6 is not required if the embodiment the equipment according to FIGS. 12 to 15 is used. To do that Pulling out the strand casing will facilitate this non-smoking casing 41, 42, 43 of the tobacco rod during the Introducing into the transfer tube 5 by a knife element 70 cut open. The knife element 70 is resilient via a leaf spring 71 through a further short slot movable in the transfer tube into its interior. The other end of the leaf spring 71 can on the housing base 2 be attached. Otherwise this embodiment corresponds the embodiment of FIGS. 1 and 2.

The embodiment shown in FIGS. 14 and 15 Tobacco portion packaging essentially corresponds to the embodiment 9, but without a predetermined tear in Perforation. This longitudinal perforation must Production of the packages according to FIGS. 5, 6 and 9 in a precisely defined distance from the adhesive seam of the flap run. This is in the embodiment according to the figures 12 to 15 not required. Cutting open the wrapping provides a significant relief when pulling out the emptied packaging without the effort for training the predetermined tear point is required.

The knife element 70 is firmly connected to the leaf spring 71. In the rest position, the tip of the knife element is outside the transfer tube 5, so that when transferring the tobacco Piston is not touched. Before the double pack 41, 42 in the Transfer tube 5 is inserted, the leaf spring 71 with attached knife element are pressed and remains in this Position until the slicing process is finished.

A double pack 41, 42 with a length can be selected be sufficient for filling a filter sleeve.

When slitting and pulling out the double pack is but a half-length version is essential in handling lighter. However, the tobacco of two half would have to Packs are transferred in two steps.

The embodiment according to FIGS. 16 to 18 largely corresponds the embodiment of Figures 1 to 3, wherein also the device according to Figures 12 and 13 can be used. The The difference is in the embodiment of the portion packaging 22 according to FIG. 19, which over its entire length and approx. 15 mm above with an unusable, tearproof material strip 75 is provided.

After inserting the portion package 22 into the transfer tube 5 of the device, the protruding material strip 75 is folded over and when transferring the tobacco rod to the transfer tube holder 3 pressed. In the final transfer of the The tobacco rod with the aid of the piston 16 according to FIG. 18 remains the portion pack in a stable position.

After attaching the filter sleeve and after transferring the tobacco the empty wrapping at the protruding material end 75 pulled out.

When using this portion pack, the transfer tube needs 5 do not be slotted. Furthermore, it is also here possible two or more transfer tubes parallel to each other to be attached to a common housing base and accordingly a number of portion packs over their strips of material 75 to connect with each other.

FIGS. 20 to 22 show an embodiment of the equipment shown, with the two cigarettes through the Consumers can be manufactured. In this embodiment jump respective first end portions 105A and second End portions 105B in opposite directions from one Housing base body 102 from before.

Here, the first end sections 105 are used to slide them on the filter cigarette paper tubes 30 while the second end portions serve to hold the portion packs 41, 42. In this embodiment, the first end portions are 105A unslotted, while the second end portions 105B are similar the embodiments of Figures 1 and 2 are slotted and to accommodate a double portion package according to FIG. 9 serve. Of course, portion packs could also be used here according to FIG. 19 or portion packs free from a predetermined tear point be used when the knife element according to FIG 12 would be used in the second end portions 105B.

The length of the end portions 105B is dependent on that Length of the portion packs 41, 42, 43 chosen, as well like the filter cigarette paper tubes 30 in an exploded manner View shown in Figure 20 based on the equipment 101 are. If portion packs with half or one Thirds the length of the filter cigarette paper tubes used the transfer process, if necessary much easier.

With the help of the double piston shown in particular in Figure 22 the tobacco strands from the second end portions 105B in the first end sections 105A and thus into those pushed onto them Filter cigarette paper tubes transferred. This one too Transfer process is accomplished through the use of double-portion packs half or a third of the length of the Filter cigarette paper sleeve relieved.

An embodiment of the equipment that is particularly for Portion packaging is suitable, which is on a belt-shaped Carrier, for example according to Figures 25, 26, 27 and 28 is shown in Figures 23 and 24. Also at This device extends similar to the device according to the Figures 20 to 22, the transfer tube 205 with its end portions 205A, 205B in opposite directions from one Holder 203 of the device body 2, the first End portion 205A for receiving the filter cigarette paper tubes serves while the end portion 205B for receiving the on the belt-shaped carrier attached portion packs formed is. For this purpose, the second end portion 205B cannot only slotted but preferably trough-shaped with an im essentially semicircular cross section, so that the tobacco portion packs attached to the belt-shaped carrier inserted in this hollow and then with Transferred to the first end portion 205A by means of a piston can be.

For aligning the belt-shaped carrier or the tobacco portion packs can the holder 203 with correspondingly shaped Projections 207 may be provided which are in respective notches or Bevels on both sides of the tobacco portion packs 22 according to FIGS. 25 to 28. The belt-shaped carrier 252 aligns the tobacco portion or portion portion packs 22 in the manner shown in FIG. 24 still in height opposite the transfer tube 205.

As can be seen from a comparison of FIGS. 25, 26 and 27, 28 can be seen here are portion packs with half or entire length of the filter cigarette paper tubes conceivable, or also other even parts of this length. The belt-shaped Carrier can be made of cardboard or relatively stiff paper, for example exist, whereby this material as such is not smokable, although this is particularly the case with the embodiment according to Figures 27 and 28 due to the short length of the tobacco portion packs not possible.

As shown in Fig. 31, the individual portion packs can also with a half or a third of the length of the Filter cigarette paper sleeves be formed and therefore due their short length should not be smokable. This information, both full length, half length and Length of a third of the length of the filter cigarette paper tube are of course only general information, at least the full length of the cigarette paper tube Portion packaging is slightly longer than their tobacco room and of course the same applies to the tobacco portion packs with an integral part the length of the filter cigarette paper sleeve, as a certain compression occurs.

29 and 30 show a further embodiment, with the three portion or partial portion packs are glued to a stiff core 253 in the middle. This embodiment of the portion packs is special for the equipment according to FIG. 23, but also for any other equipment suitable. As especially from the enlarged 30 can be seen the portion or partial portion packs with each other are not glued, but only over adhesive layers 254 with the rigid material core 253 connected.

An essential basic idea of the invention is the use of an industrial prefabricated product in the form of one with one Strand casing encased tobacco portion strands in particular Training, in conjunction with a device that a a basic body of the housing supported, if necessary has slotted transfer tube into which the prefabricated product is introduced so that the strand casing of the prefabricated product can be pulled off to the side or to the rear so that the now in the transfer tube without casing against the smooth Inside portion of tobacco serving with one from the end of the Long tube inserted into a slotted tube Transfer the transfer tube of the rolled-up cigarette paper tube can be.
