EP1772068A1 - Pack of tobacco portion and stuffing device - Google Patents

Abstract

The pack (1) has an oblong casing (2) for covering the tobacco portion. A space enclosed by the casing has a cross section transverse to the longitudinal direction of the pack. The cross section is constant over the longitudinal direction, and the largest diameter of the cross section is larger than the inner diameter of cigarette such as larger than 8.3 millimeter. An independent claim is also included for a plug device for manufacturing a cigarette.

Description

The present invention relates to a tobacco serving package for providing a tobacco portion for producing a cigarette or the like, having an elongate casing for wrapping the tobacco portion. The invention further relates to a stuffing device for producing a cigarette.

Such a tobacco sachet packaging is known for example from the EP 0 818 961 , Accordingly, a tobacco filling of a finished cigarette is provided in a strand casing, wherein the tobacco portion contained is adapted in cross section and length of the tobacco receiving space of a cigarette paper tube. Such tobacco filled casing is intended for use in a stuffing device for making a cigarette. For this purpose, the filled strand casing is inserted into the stuffing device, longitudinally slightly pinched, the strand casing pulled out laterally so that the tobacco portion remains without shell in the stuffing device, and the remaining tobacco portion, which is already adapted to the cross section and the length of a cigarette paper tube in a such pushed in by means of a slider in the axial direction.

The disadvantage here is that the strand casing on the one hand must have a strength which is suitable to hold the tobacco portion, on the other hand, however, must be easily opened by pulling on a grip tab, thereby releasing the tobacco in the stuffing device without the Stranghülle thereby unfavorably ruptures and partially remains in the stuffing device, thereby affecting the functionality of the stuffing device.

Furthermore, pre-portioned tobacco products are known which have a cylindrical casing of the tobacco portion which is open at the end faces. The envelope is firmly glued to an axial seam, which can not be opened. For producing a cigarette, such a tobacco product is placed in a tamping machine which is suitable for pushing the tobacco portion out of the casing in the axial direction and into a cigarette tube. The wrapping must not be damaged and will only be removed after pushing out the tobacco portion from the stuffing device. Such a tobacco product places high demands on both the manufacturing accuracy, as well as the strength of the seam and on the inner surface of the envelope, which must have the lowest possible coefficient of friction. If one or more of these high requirements are not met, a problem-free pushing out of the tobacco portion from the casing while simultaneously pushing this tobacco portion into the cigarette tube is endangered.

Still further tobacco products are known in which a tobacco portion is provided in a cylindrical shell, wherein the tobacco portion including this envelope is to be pushed in a cigarette tube. The casing consists of an extremely thin material, which is additionally perforated in such a way that the tobacco product can only be smoked with the help of another wrapping, such as a cigarette tube. Also in this tobacco product high demands are placed on the production of the same. In addition, the perforated wrapper in the manufactured cigarette may therefore influence the pollutant values of the cigarette, which must be taken into account accordingly in the production.

A disadvantage of these known tobacco products are the described high demands on the manufacturing quality.

Object of the present invention is thus to provide a further tobacco sachet packaging.

According to the invention, a tobacco sachet packaging according to the preamble is proposed, which is characterized in that the space enclosed by the casing has a cross section transverse to the longitudinal direction of the tobacco sachet, which is substantially constant over the longitudinal direction and whose size diameter is greater than the inner diameter of a commercial cigarette, in particular greater than 8, 3 mm. Preferably, the cross section of the enclosed space is greater than the cross section of a commercial cigarette, in particular greater than π 4.15 ² mm ² , that is larger than the cross section of a cylinder with the diameter of 8.3 mm. In this way, a tobacco portion can be provided to then be used for producing a cigarette.

By using an elongate casing, the tobacco can already be provided here in an elongated, even, uniform distribution. By virtue of the larger cross-section or diameter thereof compared to a commercial cigarette, it is first necessary for the preparation of a cigarette to reduce the volume of the tobacco portion in the radial direction and, if necessary, to adapt it in its cross-sectional shape, after it has been removed from the packaging. By such a process, the tobacco portion is reducible to the cross-section of a commercial cigarette and can subsequently be further processed into a cigarette. Such further processing consists, for example, of inserting the tobacco portion, which is now shaped in the cross-sectional dimension, into a cigarette tube in the axial direction. For producing a cigarette, the tobacco sachet is thus independent of the cigarette to be produced at least in its diameter. The tobacco sachet packaging is thus designed primarily for the quantitative provision of a tobacco portion. It can be a uniform distribution of tobacco take place in the longitudinal direction of the tobacco sachet packaging when providing the tobacco portion. The fact that the tobacco sachet packaging is larger in cross-section or diameter than a commercial cigarette and thus is substantially independent of the diameter of a cigarette to be produced, resulting in low demands on the manufacturing accuracy of a tobacco sachet packaging according to the invention.

Preferably, the cross-section may be circular, oval, rectangular, in particular square, triangular or hexagonal, whereby further cross-sectional shapes such as any polygons or even a semicircular shape come into consideration. Such cross-sectional shapes can be directed, for example, after the outer packaging for a plurality of tobacco sachets or after a cost-producible manufacturing plant or other criteria.

It is favorable if space is provided in the tobacco serving package for about the amount of tobacco of a cigarette. The provision of such a space within the tobacco sachet can be achieved by a corresponding matching of the length of the tobacco sachet packaging and the shape and size of its cross section. By adapting the space in the tobacco sachet to the amount of tobacco of a cigarette, the presence of the amount of tobacco of a cigarette can be seen only from a completely filled state of the tobacco sachet - with appropriate packing thickness and consistency of the tobacco.

Preferably, the tobacco serving package already contains tobacco, in particular tobacco cut. Because tobacco is contained in a tobacco serving package according to the invention, it can not easily be pushed into a cigarette paper tube. Thus, a lot of tobacco for a cigarette is provided in a simple manner, without already pressing this tobacco portion at least in diameter on a commercial cigarette. In that regard, this tobacco sachet packaging is flexible in its applications.

The preferred provision of tobacco in unpressed form results in a higher volume requirement in the tobacco sachet packaging compared to the intake of pressed tobacco, so that the tobacco is better adapted to such a volume due to the lack of pressure. Because of the lack of pressure on the tobacco, it tends to form less a strand, and more likely to remain as loose tobacco.

In a favorable embodiment, the shell of the tobacco sachet packaging consists of a flat material such as paper and is preferably rolled. The production of a shell made of flat material such as paper is particularly simple. Especially for the tobacco industry, the use and processing of such material is common. For example, a simple method of manufacture is to cut the flat material to a known size and then roll the cut piece to make the tobacco sachet. Also, for producing a tobacco sachet packaging which has no cylindrical shape so is not circular in cross-section, a flat material such as paper is cheap to use, whereby the shell may be rolled, for example, followed by another production step for the formation of a non-circular cross-sectional shape. The flat material during production preferably forms a jacket, such as a cylinder jacket, which is adhesively bonded, in particular partially glued along an overlapping region, in order to form an axial seam. The bonding by means of an at least partially formed axial seam is also carried out in a simple manner. The seam can be done before or after rolling as well as before cutting the flat material. There are low demands on the adhesive force, especially when using unpressed tobacco.

In a preferred embodiment, the jacket overlaps at least externally beyond the region of the seam, so that a protruding, spreadable jacket strip is formed. When the flat material has been rolled over the entire length as seen in the rolling direction, this jacket strip can also be clinging over the seam to the tobacco sachet packaging. Likewise, this jacket strip in the case of a cylindrical Tabakportionsverpackung tangentially protrude from the same. For example, in a triangular or rectangular shape of the tobacco sachet according to a section transverse to the longitudinal axis, the skirt strip may appear as an extension of an outer surface of the tobacco sachet. However, these are only various possibilities of the jacket strip to appear before the use of the tobacco sachet packaging. In any case, according to the said embodiment, the jacket strip is designed such that it can be gripped, in particular, by two fingers of a human hand and spread apart from the tobacco portion packaging.

Preferably, the jacket strip is designed so that can be pulled at the same time holding the remaining tobacco sachet to him to open the tobacco sachet packaging. Conveniently, the tobacco sachet packaging is designed so that the bond is easy to solve, in particular that the bond can be solved by pulling on the protruding coat strip without the coat strip breaks. This makes it easy to open the tobacco sachet packaging and remove contained tobacco. The ease of solubility of the bond can result in addition to the use of only a correspondingly weakly adhesive adhesive by the size of the effective adhesive surface. For this purpose, the adhesive may be formed, for example, only at points to a few adhesive points or in the sense of a series of many adhesive points.

In an alternative embodiment, it is provided that the bond is difficult to release, in particular that the bond can not be released by pulling on the projecting jacket strip, but instead tears the jacket strip or the envelope at another location instead beforehand. In this way, a stable shell can be provided insofar that in particular an automatic or unintentional opening of the shell is achieved. In addition, a Festklebnaht facilitate the production of a tobacco portfolios packaging insofar as that no precise adjustment and monitoring of the adhesive strength needs to be done, since the strength of the bond can be arbitrarily high, as long as it has only a minimum strength. Such a minimum strength may be selected so that more force is required to release the adhesive seam, as for tearing the shell or a distensible jacket strip. But the minimum strength can also be higher or lower and, for example, the double or half force to resist, which leads to a rupture of the shell or Manteistreifens. It is assumed that a uniform and not jerky force.

To open such a tobacco sachet packaging, in which the bond is difficult to solve, it may be appropriate to open it by a corresponding device for opening, such as a knife or similar cutting tool. In order to simplify cutting of the envelope, at least in sections an easily cut material is preferably used. Such a material may, for example, be designed to be particularly stiff in order to withstand the guidance of a knife without buckling, but being cut.

Since the casing of the tobacco sachet packaging finds no further use after the removal of tobacco, in the described opening of the tobacco sachet packaging and a detachment of parts of the flat material may be expedient, but at least acceptable. Since the tobacco sachet packaging is not the subject of the cigarette to be produced, in principle, no pollutant values to be observed for cigarettes need to be taken into account in the production of the tobacco sachet packaging. As a result, a wide range of possible materials can be used both for the selection of the flat material and for the selection of the adhesive. The selection of materials can be based essentially on their material and processing costs.

According to a further embodiment, the tobacco sachet has two end faces which are open. This results in a simple configuration. The elongated shape of the tobacco sachet counteracts the slipping out of any tobacco portion contained in the tobacco sachet despite open end faces.

Due to the open design of the front sides, a tobacco sachet packaging can be produced, which consists only of a jacket, which envelops the tobacco portion to be provided. By removing this shell, therefore, only the optionally contained tobacco portion remains.

Preferably, a tobacco sachet packaging is proposed which is characterized in that it can not be consumed, in particular that the casing is not flammable. This prevents accidental smoking of the tobacco sachet by the user. This avoids accidentally smoking a tobacco serving package which is unsuitable for smoking due in particular to the material contained therein.

The flat material preferably comprises aluminum, in particular an aluminum coating. By using aluminum in sufficient quantity, non-usability of the tobacco serving package is achieved. In this case, the aluminum may be present as an exclusive material such as aluminum foil. Preferably, however, a flat material, in particular paper with aluminum is used, wherein a multilayer material such as paper with aluminum foil is also suitable.

Furthermore, it is favorable for aluminum that this is easy to work.

According to yet another preferred embodiment, the tobacco sachet packaging is characterized in that the aluminum coating facing outward. As a result, in addition to the above-described advantages of aluminum, a pleasing appearance can be achieved. Furthermore, the visibility of the aluminum underscores the unusability of the tobacco sachet packaging. If the aluminum coating does not point inward, a favorable frictional behavior of aluminum can not be used in the tobacco portion packaging, ie towards the tobacco. However, it has been recognized that in the tobacco sachet packaging according to the invention, in particular when removing the tobacco by removing the casing by pulling on a spreadable casing strip a favorable friction behavior inside the tobacco sachet packaging is unnecessary. This is all the more true, as only unpressed tobacco is included. Instead, the external properties of the aluminum coating on the outside can be used. In addition to the above-mentioned visibility, this also includes the Kantaktverhalten to objects, with which the tobacco serving packaging comes into contact.

For example, aluminum is also suitable for applying a writing, a symbol, a pattern, or the like without the use of paint alone by embossing or using different roughnesses and employing other surface properties. Such an application can lead to both an optical and a palpable effect.

According to the invention, a stuffing device is also proposed for producing a cigarette, in particular using a tobacco-serving packaging according to the invention, with a means for opening a tobacco-serving packaging, which is preferably designed as a cutting means, in particular a knife. To produce a cigarette, this stuffing device tobacco is inserted into a tobacco sachet, in particular inserted and opened in a further or the same step, the tobacco sachet, so that the tobacco contained can be removed. To open a cutting means is used here, which cuts open, for example, an elongated tobacco sachet in its longitudinal direction. Subsequently, the sheath of the thus opened tobacco sachet packaging can be removed, wherein the tobacco remains in the stuffer to be used for the further production of the cigarette.

The stuffing device is in this case preferably characterized by an elongated interior for inserting a tobacco serving package. This is particularly advantageous in order to be able to use a tobacco serving package according to the invention for the stuffing device. Preferably, the cutting means for the method along a longitudinal axis of the interior is formed. As a result, by a knife that is much shorter than a cut tobacco to be cut tobacco packaging may be formed, cut an elongated tobacco sachet packaging along a longitudinal axis. The thus cut tobacco sachet packaging is then in a simple manner, for example, laterally removed through a slot from the stuffing device.

For the further production of a cigarette, it is favorable that the elongated interior is variable in size transversely to its longitudinal axis. Due to the variability of the interior in the size transverse to its longitudinal axis, this can be used to accommodate a Tabakportionsverpackung whose largest diameter is greater than the inner diameter of a commercial cigarette. From such a tobacco sachet packaging, the tobacco contained can be removed and remain in the interior of the stuffing device. Subsequently, the interior can be reduced in size, whereby the contained tobacco portion pressed and thus reduced at least in its cross-section transverse to the longitudinal axis. As a result, due to the variable size of the interior, a tobacco portion contained can be adapted to the size of a cigarette that is to be supplied.

Preferably, at least two mutually movable shell elements or the like are provided for changing the size of the inner space. The reduction of the interior can thus be achieved, for example, by moving the at least two movable shell elements towards one another. Such movement may be in translatory, rotational or other, including combined movements. In a particularly favorable embodiment, the at least two shell elements are arranged pivotably relative to one another. Such a pivoting of the shell elements against each other also includes the variant that a shell element is firmly connected to other elements of the stuffing device, and the other shell element is arranged pivotally thereto. The pivot axis in any case runs approximately parallel to the longitudinal axis of the interior.

A variability of the at least two shell elements to one another can also be achieved by an elastic connection between the respective shell elements to reach. In addition, a variability of the elements can be achieved in that they are not or only loosely connected to each other, for example by connectors, or one or more shell elements are movable in a main body, for example arranged displaceably.

More preferably, the stuffing device has a holding means for holding a cigarette tube to be filled, in particular a filter cigarette tube. Thus, a cigarette tube can be held by the stuffing device, in order then a tobacco portion already adapted to the size of the cigarette tube to be filled are transferred into the held cigarette in order thus to fill the cigarette tube. A cigarette would thus be made and can be removed from the holding means and thus the stuffing device. According to a further preferred embodiment, the stuffing device has a slide for displacing a tobacco portion into a cigarette tube. Such a slide serves to carry out the transfer of the tobacco portion, which has already been adapted in its diameter to that of a cigarette tube to be filled. The size-adapted tobacco portion is thereby pushed in its longitudinal direction and thus in the longitudinal direction of the interior of the stuffing device in the cigarette tube.

By means of a stuffing device according to the invention and a tobacco serving package according to the invention, it is thus preferable to produce a cigarette in which a tobacco portion packaging is first inserted into the interior of a stuffing device. In the next step, a longitudinal cutting of the tobacco sachet by the cutting means or there is a cutting of the tobacco sachet by and thus upon insertion into the stuffing. The thus cut-up envelope can then be removed laterally from the stuffing device. Subsequently, the tobacco portion remaining in the interior of the stuffing device compresses in its cross-sectional dimension. Finally, a cigarette tube is inserted into a holding means having a centering piece for centering the sleeve, and the compressed tobacco portion is inserted into the cigarette tube by means of a slider or a stopper pushed. The cigarette is thus made and can be removed from the stuffing device.

Figure 1 shows an approximately cylindrical tobacco sachet 1 having a diameter D, which is larger than that of a commercial cigarette according to the invention. The tobacco sachet 1 has a shell 2, which consists of coated paper and thereby encloses the tobacco contained 4 in the form of a roll. This role is held together by an adhesive seam 6, Since the adhesive seam 6 is not visible in a view according to the figure 1, it is shown in dashed lines. The casing 2 continues beyond the seam 6 and thereby forms a spreadable casing strip 8. The casing strip 8 is slightly weaker in relation to the rest of the casing 2 so that it already protrudes slightly from it.

The tobacco sachet 1 is designed open at its end faces 10, so that the tobacco 4 is visible. A possible slipping out of the tobacco portion of the tobacco portion packaging is counteracted substantially by the elongated shape of the tobacco sachet and thus the shell 2. It results on the inside of the shell 2, a large friction surface through which a corresponding holding friction force is present for tobacco portion. In this case, the coefficient of friction of said inner surface is high. A low coefficient of friction is not required for removing the tobacco portion, since this is not intended for axial pushing out of the casing 2. The removal is rather provided by opening the shell 2 at its adhesive seam 6.

FIG. 2 shows a second tobacco sachet 1 'which has a square cross-section relative to the first tobacco sachet 1.

The largest diameter D 'of the cross section of the tobacco sachet 1' is the distance between two diagonally opposite corners of this approximately square cross-section, as can be seen in Figure 2. The shell 2 'extends approximately at right angles to each other angled sections 3'. Two of the sections 3 'are glued together in the region of the adhesive seam 6'. From a section 3 'of the shell 2' extends beyond the adhesive seam 6 'and thus forms the jacket strip 8'.

In addition to the circular and square cross-sectional areas illustrated in FIGS. 1 and 2, a multiplicity of further shapes of the cross-sectional area are possible, such as, for example, an oval or elliptical shape. As further examples, they are called rectangular, triangular or hexagonal shapes. Selection criteria for the respective form are u. a. Production costs, aesthetic considerations as well as the achievement of a favorable pack size in packaging several tobacco sachets 2, 2 'in a larger outer packaging.

The removal device 12 shown in simplified form has, according to FIG. 3, a base body 14 with a cylindrical recess 16. The cylindrical recess 16 is open at its end faces and has an axial section 18. In the cylindrical recess 16 a Tabakportionsverpackung 1 is inserted axially, wherein the jacket strip 8 protrudes through an axial slot 18 of the removal device 12. For manual removal of tobacco 4 now only needs to be drawn on the jacket strip 8 of the shell 2 in the radial direction. By such pulling the tobacco sachet 1 is pulled against the axial slot 18. The removal device then holds back the tobacco sachet 1, whereby force acts on the adhesive seam 6 which leads to the release of the bond in this area. In this case, the shell 2 will first rotate together with the tobacco 4 in the cylindrical recess 16 until the tobacco 4 falls out and remains in the cylindrical recess 16. The thus opened shell 2 can now be pulled out of the removal device 12 by the axial cut 18, so that only the tobacco 4 remains in the cylindrical recess 16. The bond to the adhesive seam 6 is so easy to solve that the process described can be performed without the jacket strip 8 ruptures.

To produce a cigarette, it is now necessary to bring the remaining in the cylindrical recess 16 tobacco 4 in the desired shape to finally be able to make a cigarette manually. These further manufacturing steps are not apparent from the present description, in particular the removal device 12 shown in simplified form. The simplified shown removal device 12 is given only for the purpose of explaining the manual removal of the tobacco 4 from the tobacco sachet 1.

In the second removal device 12 'according to FIG. 4, the second tobacco portion packaging 1' according to FIG. 2 is inserted into the cylindrical recess 16 'with an approximately square cross-section. The jacket strip 8 'protrudes through the axial slot 18' of the removal device 12 '. Even when using the tobacco sachet 1 'with an approximately square cross-section, this is removed to remove the tobacco 4' by pulling on the jacket strip 8 'in a rotary motion, wherein the bond to the adhesive seam 6' finally dissolves. The type of removal of the tobacco 4, 4 'from a tobacco sachet 1, 1' is thus configured substantially the same even with different cross-sectional shapes of the tobacco sachet.

A cigarette tube 22 with filter piece 24 is inserted into the stuffing device 20 according to FIG. The cigarette tube 22 is held by two clamping pieces 26 when pressed against the cigarette tube 22 and a counter body. The main body 28 of the stuffing device 20 also has two laterally inserted pressure pieces 30 for compressing contained tobacco. A jacket strip protrudes upwards from the main body 28 through a slot 32 in accordance with FIG. At the inserted cigarette tube 22 opposite end face a cap 34 of a stuffer is arranged. It should be noted that FIG. 5 is only intended to show as many elements involved in producing a cigarette as possible. In fact, in normal use, a condition as shown in FIG. 5 will not occur, since the cap 34 is not in the position shown until a sheath to which the sheath strip 8 belongs is removed from the stuffing device 20.

The cigarette tube 22, the base body 28 and the cap 34 have a common central axis, as can be seen from the side view of FIG.

From the sectional view of Figure 7, a pusher 36 can be seen in addition, which is inserted axially into the stuffing device 20. The stuffer 36 includes a punch 38, and is pushed with this up to the front side of the attached cigarette tube 22. Here, a rod 40 of the stuffer 36 protrudes through the interior 42 of the base body 28. The cap 34 is in this case placed on the base body 28, so that the stuffing device 20 in the manner shown, but without patch cigarette tube 22 also suitable for transport, since they has such a compact shape.

The cigarette tube 22 is placed on a centering portion 44. The centering portion 44 is formed substantially as a chamfered tubular sleeve, of which in the figure 7 in the sectional view a half-oval can be seen.

According to FIG. 8, a tobacco portion packaging 1 between the pressing pieces 30 is inserted into the stuffing device 20. A jacket strip 8 protrudes from the tobacco serving package out of the stuffing device 20. According to FIG. 8, a rail 46 for a cutting means 48 is arranged below the tobacco portion packaging 1.

The main body 28 is formed substantially cylindrical and has on each side an opening 50 for a pressure piece 30 and an opening 52 for a clamping piece 26. According to FIG. 9, these openings 50, 52 are shown without the use of pressing or clamping pieces 30, 26.

From the front view according to FIG. 10, which reproduces the view according to FIG. 9 from the left, the interior 42 can be seen as a cylindrical space. The openings 50, 52 for the Andrückstücke and clamping pieces 30, 26 are not visible and therefore shown in dashed lines. The bores 54 serve to assemble the stuffing device 20 and are otherwise not essential for the production of a cigarette. The slot 32 penetrates the main body 28 from the interior 42 and extends in a uniform manner in axial direction. For guiding a cutting means 48, a rail 46 and a gap 56 are provided.

It is clear from the sectional view according to FIG. 12 that the openings 50 for the pressure pieces 30 have a width (height as shown in FIG. 12) which corresponds approximately to the diameter of the interior space 42.

As shown in FIGS. 9 and 11, insertion of a tobacco sachet 1 and stuffer 36 takes place from the left side. The cigarette tube 22 is inserted from the right side. The slot 32 for passing a jacket strip 8 of a tobacco sachet 1 extends to the front side for insertion of a tobacco sachet 1. The openings 50 for inserting the pressing pieces 30 occupy a majority of the main body 28 a. In the vicinity of the openings 52 for insertion of the clamping pieces 26, a circumferential projection 58 is provided for inserting the centering portion 44th

For explanation of the cutting means 48, reference is made to Figs. 13-16. The cutting means 48 includes a guide pad 60 for running in a rail 46, a web portion 62 for projecting through a gap 56, and a tray member 64 for running in an interior space 42 of a body 28 of a stuffing device 20. Furthermore, in the extension of the web portion 62, a knife 66 is present.

To use the cutting means 48 in the stuffing device 20 this is used so that the guide block 60 extends in the rail 46 and protrudes from this to be manually operated. The web portion 62 protrudes through the gap 56 in the interior 42. The shell member 64 defines a cylinder portion with a larger diameter than the diameter of the interior 42. This press the outer edges 68 of the shell member 64 from the inside against the boundary of the interior 42 and pull the cutting means 48 thus inside. As a result, the shell element 64 acts as a spring for the cutting means 48.

For the explanation of a pressure piece 30, reference is made to FIGS. 17 to 20. The pressure piece 30 is essentially elongated and has two plane-parallel sides 70, a convex outside 72 and a concave inside 74. The curvature of the concave inner side 74 is formed stronger than that of the convex outer side 72. In this case, the concave inner side 74 defines in section a circular section of a circle which has a slightly smaller diameter than the inner diameter of a cigarette tube 22. The pressing pieces 30 are thus adapted to be pressed against each other with the concave inner sides 74 in the inner space 42, while compressing a tobacco portion, which is already taken from a Tabakportionsverpackung to an approximately cylindrical shape having an outer diameter, the inner diameter a cigarette tube 22 corresponds or is slightly smaller.

The pusher 36 will be explained below with reference to FIGS. 21 and 22. The stuffer 36 has a cap 34, a rod 40 and a punch 38. The diameter of the punch 38 is slightly less than the inner diameter of a cigarette tube 22. Thus, tobacco can be pushed into a cigarette tube by means of the stuffer 36 with punch 38, whereby the tobacco and the punch can be pushed through the centering portion 44. The cap 34 has a cylinder jacket-shaped overhang 76. with which the pusher 36 can be pushed over an edge of the main body 28 in order to connect the pusher 36 with the main body 28, for example, for transport.

For explanation of the centering section 44, reference is made to FIGS. 23 and 24. The centering section 44 has a projection 78 and a beveled cylinder jacket 80. The chamfer 82 has an angle of 125 ° or 55 ° to the cylinder axis of the chamfered cylinder jacket. The outer diameter of the chamfered cylinder jacket 80 corresponds approximately to the inner diameter of a cigarette sleeve 22 to be pushed over it. The jacket thickness of the chamfered cylinder jacket 80 is very small and amounts to 0.01 mm in the example.

FIG. 25 shows the stuffing device 20 including the cigarette tube 22 and the tobacco sachet 1 in an exploded view, with reference to which a sequence for producing a cigarette will also be explained below.

To produce a filter cigarette, first a tobacco portion packaging 1 is inserted axially into the base body 28 of the stuffing device 20. A Manteistreifen 8 of the tobacco sachet protrudes out through the slot 32 and is guided when inserting the Tabakportionsverpackung in this in the axial direction.

After the tobacco sachet 1 is completely inserted into the main body 28, it is cut according to the figure 25 on its underside by means of the cutting means 48. For this purpose, the cutting means is initially located on the side facing the cigarette tube and is pushed once again over the entire length of the rail 46, in which it is guided, for cutting the tobacco portion packaging. The base body 28 is closed by a terminal edge 84, so that the cutting means 48 can not slip out of the main body 28. However, the end edge 84 also has an opening for extending the slot 32, so that as described the skirt portion 8 of the tobacco sachet 1 can be inserted.

After the tobacco sachet 1 has been cut open by the cutting means 48, the casing 2 of the tobacco sachet 1 is pulled out of the stuffing device 20 on the casing strip 8 through the slot 32. It remains the tobacco in the interior 42 back.

In the next step, a compression of the remaining tobacco by the Andrückstücke 30. The tobacco is in this case compressed to a cylinder with a diameter slightly smaller than the inner diameter of the cigarette tube 22. For this purpose, the pressing pieces 30 are pressed against each other.

Furthermore, a cigarette tube 22 is placed on a centering portion 44 and held on this by squeezing the clamping pieces 26.

About the pusher 36 is then pushed with its punch 38 of the tobacco in the axial direction through the centering portion 44 into the cigarette tube 22. Thus, the cigarette is made and can be removed from the centering 44.

It is therefore proposed according to the invention a tobacco sachet for providing a tobacco portion for producing a cigarette, in particular a filter cigarette, which provides a tobacco portion in a simple manner by specifically providing a tobacco portion that leaves all forms open at least in shape and size of the cross section transverse to the longitudinal axis , so that a variety of uses of the tobacco portion are opened. According to the invention, a stuffing device for producing a cigarette from a tobacco-serving packaging according to the invention is also proposed.
