A fine-cut-tobacco portion pack (50) for use in making home-made cigarettes contains a wrapper (52) which encloses on all sides a fine-cut-tobacco filling with at least one separated tobacco portion for making a cigarette. The wrapper (52) is preferably provided with an opening device (58) for opening the wrapper (52).

Description

The present invention relates to a package with a partial amount of strand tobacco for use in the proper manufacture of cigarettes, as well as to a process for the manufacture of packages with a partial amount of strand tobacco of this type.

For the own elaboration of cigarettes there is the possibility of “rolling”, in which the user extracts stranded tobacco from a larger reserve package and surrounds it with a smoking paper, where appropriate with the use of a filter. In a similar procedure, the user introduces loose strand tobacco into a sausage device and pushes the tobacco inside a previously manufactured cigarette sleeve. In both cases the user must estimate the size of the portion of tobacco necessary for the cigarette, so that the amount of tobacco can vary greatly from one cigarette to another. When the tobacco is extracted from the reserve package and when it is divided, it is easily produced in dirtying the environment, since small snuff fragments fall. In addition, it can be soiled by the user's fingers. Generally, this type of cigarette-making is very cumbersome, regardless of whether the cigarette paper is rolled manually or with the help of a mechanical device around the tobacco portion or if a sausage device or cigarette caps is used previously manufactured.

EP 1 347 690 B1 discloses a package with a partial amount of strand tobacco for the proper manufacture of cigarettes, in which a filling of strand tobacco is surrounded with a tube-shaped wrap, opened by both ends, of material that cannot be used. This wrapper is inserted into a previously manufactured smoking paper cap and then the tobacco is transferred with the help of a sausage device to the smoking paper cap, while the wrapping is removed. This package with a partial amount of strand tobacco is part of a system that also requires previously manufactured cigarette paper caps and for this reason is not intended for users who prefer to "roll" cigarettes.

The invention raises the problem of finding a possibility to facilitate the own elaboration of cigarettes, especially the "bundling" of cigarettes or the sausage, mentioned at the beginning, of loose tobacco with the help of a sausage device.

This problem is solved by means of a package with a partial amount of strand tobacco with the characteristics of claim 1, a system with a number of packages with a partial amount of strand tobacco of this type according to claim 15 as well as by a method for the manufacture of packages with a partial amount of strand tobacco of this type with the features of claim 17. Advantageous structures of the invention result from the dependent claims.

The package with a partial amount of strand tobacco according to the invention is suitable for use during the elaboration of cigarettes itself and has a wrapper that surrounds a filling of tobacco strands everywhere. The filling of tobacco with strand tobacco preferably has a portion of tobacco for the elaboration of a single cigarette; at the same time, this portion of tobacco is separated per se, since there is no other portion of tobacco. Alternatively, the wrapper may contain a stuffed tobacco of strand tobacco with several portions of tobacco separated from each other, which makes it possible to make several cigarettes. In this case and in what follows, a "portion of tobacco" means the amount of strand tobacco that is needed for a ("1") cigarette.

The package with a partial amount of strand tobacco according to the invention makes available to the user, after opening the coating, a portion of tobacco for the elaboration of a cigarette, without having to take and place it beforehand, in a very cumbersome way , tobacco from a major reserve package. Thanks to this, the contamination of the environment is also prevented, or at least significantly reduced, as well as the contamination of the tobacco. The own production of cigarettes, in particular by "rolling" or by sausage with the help of a sausage device for loose tobacco, is greatly simplified by the package with a partial amount of strand tobacco according to the invention. In the event that the packaging is tight, it also retains the moisture in the tobacco and preserves the freshness and aroma of the tobacco filling of tobacco strands, which leads to a marked increase in quality.

When the stuffing of tobacco of strand tobacco presents portions for the elaboration of several cigarettes, for example for two cigarettes, of a few cigarettes or also of a large number of cigarettes, these portions of tobacco are separated, that is to say previously portioned, of so that the aforementioned advantages are also achieved.

In preferred structures of the invention, the coating is provided with an opening device for opening the coating. An opening device of this type facilitates the opening of the lining, especially when auxiliary means are not used for this.

It is also, however, also imaginable to provide a device, with the aid of which a stuffed tobacco tobacco filler contained in the lining can be wrapped with smoking paper or can be introduced into a previously manufactured smoking paper cap, with an additional device whose drive opens the lining.

When the coating has an elongated basic shape, so that a longitudinal direction is provided, an opening device, for example, a longitudinal perforation of the coating or a longitudinal seam stuck by points of the coating, is also considered transverse perforations, for example perimeter transverse perforations at both ends of the cladding. Opening devices of this type are weakening of the coating, in which the user can tear the coating in a certain way. Another possibility is a longitudinal groove in the lining, which the user can access, in order to completely separate the lining from the tobacco gut.

When the coating must be airtight, for example a tear strip or a tear thread as an opening device, as already known as such, are suitable. Other examples are a notch at the edge of the coating, which represents an aid in tearing the coating, a torsion zone in the coating, that is to say an area (preferably at the end of the coating), in which the coating is twisted, or ropes and threads, with which the lining is tied (for example in a torsion zone). In addition, a cover can be imagined as an opening device, for example in the case of structuring the cover as a paper sleeve, a cover that can be removed on one of the front sides. The opening devices mentioned in this section do not require any coating with a predetermined longitudinal direction and are therefore also suitable for coatings that do not have an elongated basic shape.

Suitable materials for coating are, for example, paper, aluminum foil, in general metal foils, plastic foils, aluminum coated papers, plastic coated papers, laminates or nonwoven materials, also perforated material. The coating is preferably non-smokable. Other possibilities for the lining material are cardboard and metallic foil with aluminum.

The stuffing of tobacco of strand tobacco is preferably adapted, as for its shape, to a finished cigarette. In this case, the user does not need to shape it or has to do it only slightly, after removing the tobacco filling from the coating. An example for a suitable liner is a cylindrical basic shaped liner, which is sealed (i.e. for example bonded or welded), at both ends in a flat seam area, that extends transversely, or that is twisted and / or tied at both ends (for example surrounded by a rope, even without knot formation). Preferably this coating is not formed by two layers that are sealed in seam areas projecting outward on two opposite longitudinal sides of the coating.

Said at least a portion of tobacco may also be formed in a compact manner, for example as a pill. When the coating is structured as a blister packaging, such a compact form is especially advantageous, since at the same time the portion of tobacco (or a portion of tobacco chosen previously in the case of several portions of tobacco in a common coating) It can be expelled by pressure from the coating similar to a tablet.

In a preferred embodiment, said at least one portion of tobacco has a cylinder-like shape and is surrounded, within the liner, by a sleeve-like liner shell, preferably paper. At the same time, it can be, for obtaining a compact shape, the diameter of the shape similar to a cylinder at least as large as its length. Particularly advantageous is the structuring when several portions of tobacco are found in a common coating, since the coating envelopes provide a separation of the tobacco portions.

To facilitate handling by the user, a certain number of packages with a partial amount of strand tobacco may be arranged next to each other, the packages with a partial amount of strand tobacco being connected to each other by means of a clamping device. For this purpose, for example, at least one strip of material, preferably paper, may be used on which the packages with a partial amount of strand tobacco are fixed.

In a process according to the invention for the manufacture of packages with a partial amount of strand tobacco, a continuous linear arrangement of strand tobacco is manufactured on a continuous endless machine and portioned into individual portions (which are preferably elongated, but which can also have a compact form). These individual portions are subsequently coated with the coatings of the packages with a partial amount of strand tobacco, a part of the process steps necessary for this being possible, however, also before said fractionation. In this case, an individual portion presents a portion of tobacco for the preparation of a (figure "1") cigarette. It is possible to introduce each individual portion in a separate coating or in each case introduce several separate individual portions in a common coating.

During the realization of the process according to the invention, a conventional endless endless machine can be used, which has the advantage of a very high working speed. As the only intervention in the existing continuous procedure, strand tobacco must be divided into individual portions; For this, some possibilities are indicated below. After having prepared the individual portions, they can be coated with the help of conventional process procedures. As indicated above, it is also possible to carry out a part of the coating steps previously during the continuous process (see below). The process according to the invention, therefore, works fast and is economical, since it is essentially based on existing technology.

One possibility of splitting the strand tobacco consists in interrupting the continuous linear arrangement of the strand tobacco at uniform distances so that the desired portions are formed between the interruptions. The interruption can be carried out, for example, by two cutting discs. At the same time, the tobacco circulates on two rotating cutting discs, whose axes are oriented parallel to each other and perpendicular to the direction of transport of the tobacco. The surfaces of the cutting discs are formed in such a way that they engage at each turn of the cutting discs at least once in the tobacco stream and, thereby, displace the particles of strand tobacco that is It forms an interruption, that is, a tobacco-free zone.

In a preferred structuring of the process according to the invention, the strand tobacco is surrounded, for fractionation in a conventional cigarette machine for each individual portion with a lining shell open at both ends. The coating wrap is preferably paper. This structuring of the process has the advantage that a continuous production chain, in which cigarettes with a lining of cigarette paper can be made, does not have to be practically modified to produce individual portions surrounded with a liner wrap for tobacco fillings of tobacco of thread according to the invention. The only difference is that for the cost savings for the lining envelope, no smoking paper is used, but rather very cheap paper. The lining envelopes have only the task of keeping the individual portions together so that they can be handled and transported well. The individual portions can be manufactured accordingly at high speed in an installation actually mounted for the production of conventional cigarette sections and can be automatically positioned with the help of the coating wraps, whereby this process structuring is especially advantageous The lining envelopes of the individual portions are removed in a preferred embodiment, before the individual portions are surrounded with the lining of the packages with a partial amount of strand tobacco.

For the removal of the lining shells, an individual portion can be introduced in each case with a lining shell in a housing space, for example a hole that serves as a housing, and be fixed therein, preferably with the help of a depression , the individual portion being ejected out of the lining shell, preferably pneumatically. At the same time the corresponding individual portions are ejected on a transport device, for example, a conveyor belt, in which each individual portion is housed in a recess. During this stage of the process, a rotating revolver is preferably used, which has a number of housings for the introduction, in each case, of an individual portion with a cladding shell, the revolver delivering the individual portions ejected from the cladding shell corresponding in a transport plane different from the introduction plane. From there, the individual portions can be transported with a transport device, for example the conveyor belt mentioned above, to a station in which they are coated with the coatings of the packages with a partial amount of strand tobacco.

It may also be advantageous that the coating envelopes of the individual portions are not removed prior to the coating of the individual portions. Thanks to this you can, on the one hand, save costs. On the other hand, such an embodiment is especially practical, when several separate tobacco portions have to be coated with a common coating, since then the coating envelopes keep the individual portions separated. In this case, the user removes the lining shells, which can be provided, for example, by a device in a sausage apparatus.

In another structuring of the process according to the invention, the strand tobacco is stabilized as to its shape before fractionation. Thus, it is imaginable to freeze the strand tobacco, for example with liquid nitrogen and cut it into the desired individual portions before defrosting. In another type of form-stabilization, the individual portions are stabilized as to the form after fractionation, so that they can continue to be processed easily or transported far more easily. In this case, liquid nitrogen can be reused, for example, or networks for example corresponding individual portions are used, which at a later stage of the procedure are removed again in a similar manner to the coating casings. Another possibility of stabilization in terms of form is to glue the strand tobacco or the individual portions, for example with the help of a sugar or starch solution.

In the process according to the invention for the manufacture of packages with a partial amount of strand tobacco, the corresponding coatings can be structured as sections, which run transversely, located next to each other and separated by sealing seams, of a continuous bag without finish. From a continuous endless bag of this type, they can be manufactured, by means of cuts that lead longitudinally through the sealing seams and that leave at the same time intact a sealing seam corresponding to both sides of the cutting line, packages with a partial amount of individual strand tobacco. These portion packages can then be packaged in a larger unit and can be supplied in this way to the user.

It is also imaginable to make available to the user a larger section of the endless continuous bag with a certain number of packages with a partial amount of strand tobacco. At the same time, preferably, longitudinally, perforation lines run through the sealing seams, so that the user can easily separate a package with a partial amount of individual strand tobacco at the end of a section of continuous bag

In a particularly preferred embodiment of the process according to the invention, the strand tobacco is surrounded in a conventional cigarette machine with a continuous coating and the wrapped section is cut, to divide it, at predetermined distances, so that individual portions are formed wrapped, each for the elaboration of a single cigarette. The corresponding coatings are then closed by their two extreme sides. For this, the strand tobacco contained in the lining is pushed, from the extreme sides, into the lining (for example with the help of pushers) and the lining is then flattened and closed at both ends (for example by sealed as adhesion or welded or by mechanical connection such as compression, punching or hooking). In this variant of the process, most of the steps can be carried out within the framework of a conventional continuous process, including fractionation and an essential part of the coating; Only the last stages of the coating (closing of the end sides of a corresponding coating) must take place separately.

The invention will now be explained by way of examples of embodiments, in which:

Figure 18 shows schematic views of process steps in another exemplary embodiment for a process for manufacturing packages with a partial quantity, and

Figure 19 shows a view of a system with a number of packages with a partial quantity which are arranged, next to each other, on a strip of material.

In Fig. 1, a first embodiment of a package with a partial amount of strand tobacco (referred to below as a package with a partial amount), which is designated with reference number 10, is shown. The package with a quantity Partial 10 has a lining 12, which surrounds on all sides a filling of tobacco with strand tobacco that is inside the lining 12 and which is not drawn separately in Figure 1. The filling of tobacco with strand tobacco corresponds in the exemplary embodiment, a portion of tobacco for the preparation of a single cigarette. In the exemplary embodiment, the liner 12 is closed. The lining 12 has a basic cylindrical shape, so that the stuffed tobacco with strand tobacco inside the lining 12 has a shape similar to a cigarette. At both ends the coating 12 is sealed in a flat seam area 14 or 15, which runs transversely. The liner 12 is therefore in the form of a cylinder with flattened ends. The concept of "sealing" should be understood in a broad way. To it belong, for example, adhesion or welding, depending on the possible sealing techniques in each case of the coating material 12.

In the exemplary embodiment, the coating 12 is made of paper coated with aluminum. Other coating materials are, in any case, possible, for example paper coated by evaporation with aluminum, aluminum foil or other types of metal foil, plastic foil or exclusively paper. When paper is used exclusively, it may be provided with perforations in order to exclude that the package with a partial quantity 10 be smoked as if it were a cigarette, without having previously removed the paper completely.

The package with a partial quantity 10 is closed on all sides, also in its longitudinal seam not drawn in Figure 1. Thus, the coating 12 forms a wrapping that keeps the strand tobacco inside it fresh.

When the user wants to prepare a cigarette, he takes the package with a partial amount 10 and tears the liner 12. In order to facilitate the opening process, a notch 16 is arranged in the sewing area 15, in which position the liner 12 It can be torn in a relatively easy way. From the package with an open partial quantity 10, the strand tobacco, accurately positioned, can be poured onto a smoking paper, so that the user can manually roll a cigarette without great complexity. Alternatively, you can use a device for this, after you have introduced the strand tobacco into it from the package with a partial quantity 10. This device may also be provided with opening means, which make it easier for the user to open the package with a partial quantity 10.

In figure 2, as another embodiment, a package with a partial quantity 20 is shown, which is structured similarly to the package with a partial quantity 10 and containing two flat seam areas 24 and 25 at the ends of a liner 22. In order to facilitate the opening process, the liner 22 has a perimeter transverse perforation 26. By means of the transverse perforation 26, the coating 22 can be easily torn apart, so that the strand tobacco inside it can be spread from the two halves of the coating 22.

In figure 3, a package with a partial quantity 30 is shown, as another embodiment, which is structured similarly to packages with a partial quantity 10 and 20 and having a liner 32 with two seam areas 34 and 35 flat at its ends. As an opening device, in this case a longitudinal perforation 38 is provided, along which the liner 32 can be easily opened, to spread the tobacco inside.

The embodiment represented in Figure 4 of a package with a partial quantity 40 is again structured, in terms of its basic form, in a manner similar to the embodiments explained above and has a cylindrical liner 42 with two areas of Seam 44 and 45 flat at the ends. Two transverse perforations 46 and 47, which run over the perimeter of the liner 42, in the vicinity of the ends serve as the opening device.

To open the liner 42, the two end pieces are removed by the transverse perforations 46 and 47. The user then obtains a cylindrical bushing with strand tobacco, which is open at both ends. This cap is used to stuff the tobacco in a smoking paper cap.

When the package with a partial quantity 40 must be used for the manufacture of a conventional cigarette, it is, however, more practical for the liner 42 to be easily opened along a longitudinal seam (not drawn in Figure 4) .

Figure 5 shows, as another embodiment, a package with a partial quantity 50 with a cylindrical basic cover 52 and two flat seam areas 54 and 55 at the ends, similar to that shown above. The liner 52 can be easily opened by a tear strip 58. The tear strip 58 is located inside the liner 52 and is directed outwardly at the end of the seam area 54, so that its end 59 is accessible, for which user can take the tear strip

58.

The embodiment of a package with a partial quantity 60 shown in Figure 6 again has a cylindrical basic liner 62 with two flat seam areas 64 and 65 at the ends. The lining 62 is closed in the longitudinal direction along a longitudinal seam area 66, in which the lining material 62 overlaps, with the formation of two layers, which are connected to each other with the help of three glued points. 67. Figure 6 shows a state at the beginning of the opening of the lining 62, when the outer layer of the longitudinal seam area 66, designated by 68, is lifted and the glued points 67 are released. By pulling the raised outer layer 68, the liner 62 can then be opened completely.

As another embodiment, a package with an elongated partial amount 70 is shown in Figure 7, in which a coating 72 is twisted at ends 74 and 75. In the exemplary embodiment, the coating 72 is joined in ends 74 and 75 additionally with ropes 76 or 77. A longitudinal seam is not shown - as in most of the previous embodiments. When the longitudinal seam of the liner 72 is not sealed, the liner 72 can be opened more easily. On the contrary, in case of a sealed longitudinal seam, the lining 72 better preserves the aroma of the tacoco tacoco filling.

In Fig. 8, a longer section of a continuous endless bag 80 is shown, which is closed on its two longitudinal sides and which is subdivided into sections by means of sealing seams 82 that run transversely, located parallel to each other. Each of these sections forms a package with a partial amount 84 provided with a liner 83, which is filled with strand tobacco. In the center of the sealing seams 82 there is, in each case, a perforation. Thanks to these perforations, packages with an individual partial amount 84 of the remaining section of the continuous bag 80 can be easily released.

Figure 9 shows a package with a partial quantity 84 of this type in an enlarged view. Two areas of relatively wide, flat seams 86 and 87 are recognized at both ends, which come from the longitudinal sides of the continuous bag 80, as well as parts 88 and 89 of the corresponding sealing seams 82 that have remained in the package with a partial amount 84 considered.

In the exemplary embodiment, the continuous bag is made of plastic, and the sealing seams 82, as well as the seam areas 86 and 87 are generated by welding. Other materials are also imaginable, and other sealing techniques can also be used.

Figure 10 shows an outer package 90, structured as a box, with a folding lid 92, in which a certain number of partial quantities 94 is contained. A box of this type is especially suitable for packages with a partial quantity of the type of the embodiments explained from Figures 1 to 7, although also for a continuous bag 80 with a certain number of packages with a partial quantity 84, connected to each other or also separated, or for partial quantities with shape stability.

In an alternative structuring, also explained on the basis of Figure 10, 94 packages with a partial quantity that are not individually coated, but individual tobacco portions, in each case for the manufacture of a cigarette, are designated by reference number, that do not have their own lining, but that are separated from each other by means of the distribution in squares represented in figure 10. In this case the box 90 is in charge of the lining function, and the folding tab 92 is an opening device for the coating.

Next, an exemplary embodiment is explained for a process for manufacturing packages with a partial amount of strand tobacco. In figure 11, a step of the procedure is represented schematically.

In the process for the manufacture of packages with a partial quantity, a continuous linear arrangement of strand tobacco is firstly processed on a continuous endless machine, surrounded with a bushing and portioned into individual portions. If these steps of the procedure were carried out completely in a conventional manner, individual cigarettes (without filter), which are surrounded in each case with smoking paper, would be supplied as product. In the present process, a simpler paper material is used instead of smoking paper; This is to this extent the only difference with the conventional procedure. The product does not, therefore, consist of finished cigarettes but of individual portions 100 of strand tobacco which, in each case, are surrounded by a lining shell 102 of a simpler paper. Other materials, for example sheet or non-woven material, can also be used for the cladding; Preferably, the lining shell material is economical and / or recyclable.

In figure 11, it is shown how the lining shells 102 can be removed, useful for the portioning process but not needed later.

This happens with the help of a revolving revolver 110, which has a certain number of holes 111 running parallel to each other. Below the revolver 110 a conveyor belt 112 moves with recesses

113.

At an insertion point 114, an individual portion 100 with liner shell 102 is inserted into one of the holes 111. Inside the hole 111, the liner shell 102 is fixed with the aid of a depression, which is applied to the hole 111 through openings in the inner wall. Meanwhile, the revolver 110 rotates to a crash point 115, in which the individual portion 100 of strand tobacco is blown out of the bore 111 with the aid of pressurized air and reaches a recess 113 of the conveyor belt 112.

The revolver 110 transports the remaining liner shell 102 to an ejection point 116, where the liner shell 102, once the depression is disconnected, is expelled to the outside with the aid of pressurized air. The coating shell 102 can then be removed or supplied for reuse.

The conveyor belt 112 has moved during the time elapsed to a supply point 117, where the individual portion 100 is removed from the conveyor belt 112 and is supplied to a conventional packaging device. In the exemplary embodiment, the individual portion 100 is positioned as a tobacco portion for the elaboration of a single cigarette. In the packaging device, the individual portion 100 is surrounded with a coating on all sides.

From Figures 12 and 13, process steps of another exemplary embodiment are shown for a process for manufacturing packages with a partial amount of strand tobacco.

In this exemplary embodiment, a linear arrangement of strand tobacco is made on a continuous endless machine and is supplied, as a stream of continuous tobacco 120 (without coating) to a portioning device, which subdivides the strand tobacco in individual elongated portions.

The portioning device has two cutting discs 122, 123 which rotate in opposite directions about axis parallel to each other and at close distance, see Figure 12. The axes of rotation are oriented perpendicularly with respect to the direction of transport of the tobacco 120 The cutting discs 122, 123 are arranged in such a way that the tobacco 120, supplied at 124, arrives essentially above the upper sides of the cutting discs 122, 123. Along its periphery, the cutting discs 122 , 123 are provided in each case with projections 126, 127, which protrude upwards, the projections 126 of one of the cutting discs 122 being oriented towards the projections 127 of the other cutting discs 123. In the embodiment example they are distributed in each case six projections 126 or 127 uniformly along the perimeter of the cutting discs 122, 123.

When the strand tobacco particles of the tobacco stream 120 access the area of two projections 126 and 127, they are ejected from the tobacco 120, see Figure 12 and Figure 13, so that in the tobacco stream 120 is formed an interruption 128. In this way, tobacco 120 is subdivided into individual portions 130. The cutting discs of the type described are also used in conventional cigarette manufacturing facilities, although in that case they are mounted upside down (the upper side towards below), so that the tobacco particles accumulate in the recesses that form "protrusions", which leads to a zonal compaction of the tobacco (reinforcement of the head in cigarettes made with this tobacco).

As shown schematically in Figure 12, in the subsequent development of the process the individual portions 130 are received, after the cutting discs 122, 123, by a belt of material 132 serving as a means of transport, of which in 134 a part is placed in the longitudinal direction above the individual portions 130, so that the individual portions 130 are enclosed between two layers, which in this embodiment are formed by a ribbon of material 132. These two layers are connected each other along a longitudinal seam and form, first of all, a continuous coating for the individual portions 130. In a station 136 this coating is crushed and closed or sealed as well as cut, at the points of interruptions 128 between the individual portions 130, whereby they are formed with a partial amount of strand tobacco 138 finishes. The coating 140 of a package with a partial quantity 138 is thus formed from the previously continuous coating. At the crushed points 142, corresponding seam areas are formed at the ends of the packages with a partial amount of strand tobacco 138.

The procedure described above of the explanation of Figure 11 can also be carried out without having to remove the lining shells again. At the same time, individual portions of tobacco are obtained, in a simple and conventional manner, which, in each case, are surrounded by a lining shell that is open at both ends. In later stages of the process, this coating envelope is provided with an (additional) coating on all sides.

Figure 14 shows, as an exemplary embodiment for the product of such a process, a package with a partial quantity 150. The package with a partial quantity 150 has a coating 152 (with a sheet 154) surrounding a portion of tobacco 156 (in the exemplary embodiment of approximately 15 mm in length and approximately 15 mm in diameter) provided with a lining shell 158 and formed here in a compact manner. The sheet 154, transparent in the exemplary embodiment, is folded in a fold line 155 and the two layers of sheet, formed therefrom, are sealed together in an area of the edge 159 that extends along three sides. After opening the liner 152, the user can remove the liner envelope 158. The liner shell 158 can also however be used to hold the tobacco portion 156 together, by introducing it into the proper device for the proper manufacture of cigarettes, being removed the lining shell, if any, of this device.

In Fig. 15, a similar embodiment is shown, this time however for several separate portions of tobacco. The package with a partial quantity, designated by 160, has a coating 162 with a first sheet 164 and a second sheet 165, which are welded together in a perimeter area of the edge. The coating 162 surrounds a certain number of tobacco portions 166, which in each case have their own coating envelope 168. The tobacco portions 166 are previously separated and portioned by the lining envelopes 168 and can therefore be easily handled after opening the liner 162.

Here, Figure 16 also shows a package with a partial quantity for several separate portions of tobacco. In this case, the package with a partial quantity, designated by reference number 170, contains a lining 172 in the form of a paper bushing 174 with a floor and a lid 175 that can be resealed. Each of the tobacco portions 176 is in a lining shell 178 and is thereby separated from the remaining tobacco portions 176. Instead of a paper bushing, a metal bushing or a plastic bushing can also be used.

In Figure 17, with parts (a) to (e), a package with a partial quantity 180 structured as a blister packaging is shown in different views. In this case, a blister piece 184 (in the exemplary embodiment made of polyester) which is closed with a flat sheet 185 (for example of plastic) has a coating 182

or aluminum). The sheet 185 is connected in its area of the margin with the blister piece 184 for example by adhesion or sealing. Instead of sheet 185, a layer of paper is also imaginable. In the partial spaces 186 formed in the blister piece 184 there is in each case a portion of tobacco for the elaboration of a cigarette. These portions of tobacco can be surrounded in each case, as before, by a coating envelope. However, it is also imaginable to fill the partial spaces 186 of the blister piece 184 directly with strand tobacco before application of the sheet 185.

The package with a partial amount of strand tobacco 180 can be handled analogously to a pack of pills, so that by pressing on the blister piece 184 the sheet 185 is destroyed over the partial space 186, so that the Strand tobacco contained in the partial space 186 can be transferred, for example, in an opening to a device for the manufacture of cigarettes.

In a variant of this embodiment, the sheet 185 can be easily removed from the blister piece 184 (for example, by means of an ear or from an edge position, which is not attached or is only slightly with the piece of blister 184), so that partial spaces 186 with tobacco portions are made accessible.

It is also conceivable to subdivide the package with a partial quantity 180 by means of perforation lines that, by breaking the perforation lines, can be separated by individual partial spaces 186 or groups of partial spaces 186 from the package with a partial quantity 180 remaining. Where appropriate, each of the partial spaces or each of the groups of separate partial spaces may be provided with an auxiliary opening means mentioned in the previous section. From the base of Figure 18, another embodiment of a process for manufacturing packages with a partial amount of strand tobacco is explained. To this end, a continuous linear arrangement of strand tobacco, which is surrounded in a continuous endless machine (in particular, a cigarette machine) with a coating, is first generated by a continuous process, as described above. continuous. This coating is made however - in a different way than before - in this case already a package coating material with a partial quantity finished. To fractionate the coated section is cut at predetermined distances, so that individual coated portions are formed which, in each case, are intended for the manufacture of a cigarette, whose coatings are not yet closed.

Figure 18 shows, schematically, how these individual coated portions continue to be processed to close the coatings. The steps carried out at the same time can be carried out in a station in a modified cigarette machine or in a modified filter added piece machine. First, there is therefore surrounded by a portion of tobacco 190 elongated in each case by a lining 192, which is open on both end sides 193, and the strand tobacco reaches the end sides 193.

In figure 8 (a), two pushers 194 are moved towards the end sides 193 and, according to figure 18 (b) they are advanced in the linings 192, so that the strand tobacco is compressed there and, after withdrawal of the pushers 194, according to figure 18 (c), there are hollow spaces 195. Instead of the pushers 194, slides, cams or mandrels can also be used. These devices are preferably mounted on one or several drums and are driven by them.

In the next step the lining 192 is crushed and closed by its two final zones with the help of presses 196, as shown in Figure 18 (d) and in Figure 18 (e). This can take place for example with the help of drums, compression belts or pressure plates. Purely mechanical techniques such as compression, punching or hooking are suitable for closing, which are carried out in the exemplary embodiment preferably in a work process with the movement of presses 196. Alternatively or additionally they can be used techniques such as welding, adhesion and / or sealing, for which an additive (for example adhesive) must be added where appropriate.

Figure 18 (f) shows the package with a finished partial quantity, designated herein by reference number 200, which is structured as the embodiment according to Figure 2. If necessary, it can be punched out, during the movements of the presses 196 a notch in one of the seam areas 198, 199, similar to the notch 16 of Figure 1.

In Fig. 19, a system is shown in which a certain number of packages with a partial quantity 200 are arranged, next to each other, on a strip of material 202. This can facilitate user manipulation. In the exemplary embodiment, a strip of material 202, made of paper, is provided on which the packages with a partial quantity 200 are attached. Other materials (for example, plastic) or other quantity of strips of material are also imaginable.
