Description

The invention relates to a smoking tobacco for self-production of cigarettes, especially using prefabricated cigarette paper tubes, consisting of a or more, each comprising at least two subsets, held together by internal / or external fixation means Tobacco portion (s), with each subset approximately the same for one Cigarette contains the required amount of tobacco, and the Mantle surface of the tobacco portion and / or the subsets such is permeable to air that they are not as such and so that it is not smokable. The invention relates also a packaging for such a smoking tobacco and a process for its manufacture.

A smoking tobacco is known from DE-C-32 44 906, consisting of from a quantity of smoking tobacco forming a sales unit in the form of approximately equal subsets, the Smoking tobacco wholly or at least partially through a wrapper is held together from completely smokable material. For making a self-rolling cigarette is everyone Subset formed like a round bar. Each subset corresponds also about the one required for a cigarette Quantity of tobacco. The wrapping of the known smoking tobacco exists made of inaccessible, perforated or mesh-like Material. The well-known smoking tobacco is by pressing, grooving, Punching, perforating, cutting, inserted threads or the like divided into round rod-like subsets. The subsets are in a preferred embodiment to form a Rod belt strung together so that they are slightly apart are solvable without the individual subsets be destroyed or without the inner cohesion of the individual subsets are lost. The known Smoking tobacco can at least in places also be a fixative Increase internal cohesion included in each subset.

The well-known smoking tobacco is said to be without any special Aids, such as auxiliary packaging, made of non-smokable Material and transfer device to make a cigarette yourself to let. This now exists in many countries Problem that a smoking tobacco of the known type, in which rod-like subsets without destroying them for self-production of cigarettes by wrapping them with cigarette paper can be separated, taxed in the same way as cigarettes. The same applies to tobacco portions according to DE-C-34 07 461 and EP-B-155 514.

As an alternative to the previously known systems for self-production of cigarettes, there is still the conventional self-rolling of cigarettes using sticky tape provided rolling papers and the stuffing of Cigarettes using pre-made cigarette paper tubes on the one hand and cigarette filling devices on the other. The two are traditional methods Disadvantage that no cigarettes can be produced, the with regard to the tobacco filling degree, the taste, the Smoking behavior (smoking time, draft), and / or the pollutant content are constant. Accordingly, according to the cigarettes manufactured using conventional methods far inferior to manufactured cigarettes.

An interim solution between the latter conventional ones Methods and the system according to DE-C-34 07 461 or EP-B-155 514 provides the system according to DE-U 8 326 921 and 8 309 186. This system is characterized by an as such non-smokable prefabricated in the form of a manufacturing prefabricated tobacco cartridge consisting of a open on the front, with the diameter of the cigarette paper tube the finished casing and the finished cigarette a strand-like, each corresponding to a portion of cigarette Tobacco filling, which is assigned by an pistons adapted to the inside diameter of the strand casing the strand envelope can be transferred into an empty cigarette paper tube is. This tobacco product is suitable for both Use in conjunction with conventional self-filling cigarette paper tubes as well as in paper tubes with conventional Even Turner cigarette paper. After this The basic idea of this proposal will become a consumer precisely dosed, namely the filling quantity of a conventional, industrial tobacco equivalent amount of tobacco in In the form of a cigarette tobacco cartridge, their tobacco filling in a relatively simple way in a prefabricated Cigarette paper tube of a commercial type or in one from a self-rolling rolling papers glued cigarette paper sleeve is transferable. adversely is that the tobacco cartridge has an envelope, namely Strand casing, which consists of non-smokable material. This Stranghülle provides "cigarette" with regard to the end product a superfluous, one-time tool.

From EP-A-0 584 805 is smoking tobacco for the Self-made cigarette described. The Smoking tobacco consists of one or more, each comprising at least two subsets, by inner and / or external fixing means held together Tobacco portion (s), with each subset approximately the same for one Cigarette contains the required amount of tobacco. The Lateral surface of the tobacco portion and / or the subsets so permeable to air that it is not draftable as such and is therefore not smokable. The tobacco serving is either formed by two or more rod-like and connected to each other to form a rod belt, in particular glued subsets, or by a two or more Flat oval tobacco unit comprising partial quantities. Based on the prior art mentioned, the present Invention, the object of a smoking tobacco create all the benefits of pre-portioned tobacco aliquots for the self-production of cigarettes as well has the advantage of tax privilege in the countries, in which rod-shaped tobacco portions, although at are not smokable, but after wrapping with cigarette paper become smokable like cigarettes are taxed. In addition, with regard to the end product "cigarette" Waste, i.e. aids not suitable for smoking, on a Minimum be reduced.

Furthermore, it is an object of the present invention a manufacturing process to provide such a smoking tobacco.

The above task is related to smoking tobacco by the characterizing features of claim 1, and the manufacturing process solved by the features of claims 16 ff.

In claims 19 and 21 are preferred methods for Home-made cigarettes using an 11th Smoking tobacco according to one or more of claims 1 to shown.

The core of the smoking tobacco designed according to the invention lies in the formation of the two or more subsets Tobacco portion in the form of a tobacco cuboid such that each A tobacco rod with a triangular or polygonal in particular rectangular, preferably square Cross section, and a length corresponding to the length of the The tobacco receiving room of the cigarette to be manufactured. The The shape of the subsets is such that they are not easily be transferred into a conventional cigarette paper tube can produce a smokable, i.e. zugfähigen Cigarette. Rather, each subset must at least with regard to of their cross-section before being converted into a prefabricated one Cigarette paper tube are brought into shape. This preferably takes place within the press chamber of a conventional one Cigarette stuffing device, with which at the same time the subset be transferred into a prepared cigarette paper tube can.

You want the cigarette to use a conventional rolling paper must be produced, the specified Form of the subset changed, in particular resolved. For this purpose, the subset is preferably first positioned on a rolling paper, then in front Wrapping the rolling papers with your fingers to be loosened up or crumbled. Alternatively, you can each aliquot before wrapping with a rolling paper with your fingers in the shape of a tobacco rod with about circular cross-section can be kneaded. Definitely is a shaping of the subset before wrapping with cigarette paper necessary. This necessity ensures that tax privilege in a variety of countries for fine cut remains. The trained according to the invention Smoking tobacco or the subsets separated from it make a special kind of pre-portioned fine cuts represents.

According to the invention are alternatively in the Separation of a tobacco cuboid in subsets the subsets in the area of their connection with a neighboring subset inevitably destroyed or broken up with the lifting of the inner cohesion in this area. This means that if a subset is separated, neither this nor the immediate adjoining subset without special precautions transferred into a pre-made cigarette paper tube can be, regardless of the cross-sectional shape each subset. If a subset is separated, the internal cohesion largely destroyed, if necessary. even so destroyed that it literally disintegrates "under the hand". The same applies to the subset separated immediately adjacent subset. Accordingly, stays with Separation of a subset is nothing more than an over the length of the tobacco receiving space of a cigarette paper tube pre-portioned amount of tobacco. The described resolution of the inner cohesion is when using a conventional one Tamping device for the production of a cigarette is unproblematic, because only the individual subsets have to be taken into account to transfer into the baling chamber of the tamping device. This can e.g. with the aid of a packaging according to claim 14 the method according to claim 20. A big advantage the smoking tobacco designed according to the invention in comparison to the state of the art according to DE-C-34 07 461 and EP-B-155 514 is that no "paper", namely no wrapping material must be smoked per tobacco portion. Thereby is the acceptance of this embodiment by the consumer significantly increased.

In order to dispense with external and, if necessary, also internal fixing agents To be able to, the tobacco is preferably so compressed that it a draw resistance approximately corresponding to the draw resistance of the Has tobacco filling of a conventional cigarette. Thereby it is also ensured that the tobacco is sufficient is dimensionally stable, in particular each subset even after separation from the tobacco cuboid according to the invention. It is also possible, according to claim 3 to inject the tobacco and if necessary, with internal fixatives such as plum juice or the like, to treat the subsets after their singulation just hold together while maintaining their given shape. This is to ensure that each subset can be held between two fingers without it disintegrates easily. So is such a subset after separation from the tobacco cuboid into the bale chamber one conventional tamping device or on a prepared, i.e. Spread out flat cigarette papers.

The tobacco cuboid can be divided into subsets by mechanical cuts, punchings, creases, embossing or The like. In this regard, they are conventional Method.

The measures according to claim are particularly advantageous 5, after which in the parting plane between two neighboring Partial quantities of a tobacco cuboid separators made of tinfoil paper, Cardboard, or the like. Relatively stiff, and by smoking Put in non-consumable material. To this Wise is a clean separation of the individual subsets receive. The dividers are also a separation aid. The dividers are preferably part of an outer envelope, in particular part of one only on one flat side and if necessary the two opposite longitudinal and / or Wrapping extending the narrow sides of the tobacco cuboid. The separators can be made in one piece with the above-mentioned covering be connected. It is also conceivable to place the dividers on the stick on the mentioned wrapping. Also a loose connection between the dividers and the mentioned covering or Partial wrapping is conceivable. The partial wrapping mentioned is preferably in the manner of a flat dish, in particular Partial shell formed.

Can be used to achieve sufficient transport strength the tobacco cuboid according to claims 7 and 8 tubular be surrounded by an envelope, the overlapping one another Sides of the wrapping are loosely overlaid. This also makes opening this envelope unproblematic. The hose-like covering preferably does not consist of material consumable by smoking, especially from Aluminum laminated paper.

The cohesion of the tobacco cuboid can also be promoted through one on the long and narrow sides extending strips of non-consumable by smoking Material, e.g. Cardboard, plastic or the like. This narrow-sided Edging the tobacco cuboid holds it together well, without much packaging material.

The rod-like subsets can furthermore each by a strand casing made of either consumable by smoking Material or material not consumable by smoking, such as paper laminated with aluminum or the like, held together be, in the latter case the overlapping Longitudinal edges of the strand casing or casing are loosely superimposed are to remove the strand casing before using the To be able to remove partial quantities with ease. Through the above Measures are supposed to be the internal cohesion of each individual subset be secured. Can inside the outer strand envelope the tobacco is relatively loosely connected, i.e. so loose that the subset after removing the strand casing decays.

As a sales unit, several tobacco blocks of the named Kind combined on top of each other to form a larger unit his.

The packaging is particularly important for you Tobacco cuboid, which is characterized by itself benefits extending around the tobacco cuboid made of relatively stiff packaging material, especially cardboard or the like, wherein the overlapping long sides together are glued. So it's a kind of outer packaging, which are around the two flat sides as well as the two Longitudinal narrow sides or alternatively the two front sides Narrow sides of the tobacco cuboid stretched out. In the latter In this case, the packaging is suitable as a kind of magazine. The tobacco cuboid can be from one open side of the packaging be pushed out of this in part quantities. The packaging can be in particular on the upper filling opening the press chamber of a conventional tamping device be then in part tobacco in the bale chamber push the packaging through. On the tamping device itself For this purpose, a suitable border should be provided that the packaging, including the tobacco cuboid, is safely and precisely positioned the filling opening of the bale chamber can be placed. The Packaging thus represents a disposable tobacco magazine. The separation of the individual subsets from the tobacco cuboid done by the press beam. So the packaging has one Multi-function, namely on the one hand it serves cohesion of smoking tobacco designed according to the invention, and others serve as a magazine or tobacco refill chute. It in this context, in particular to claim 22 directed.

To the aforementioned casing according to claims 7, 8 and 9 respectively and / or the packaging associated with smoking tobacco according to claims 12-14 can still be another packaging envelope, which is used as an aroma and moisture barrier serves. This envelope is preferably there from an air and moisture proof film, especially cellulose film or the like. This film can be printed in the same way as in the case of packaging manufactured cigarettes.

The tobacco cuboids according to the invention can thereby be produced be that a tobacco rod with an approximately rectangular cross-section continuously or intermittently on one spaced cutting or punching elements comprehensive tobacco separator is led past, through which the tobacco rod into individual on which the cutting elements opposite side preferably still together connected sub-strands is divided, and that subsequently the partial strands through an effective across the conveying direction Knife or the like. Cutting device separated from the tobacco rod become.

The cutting or punching elements can alternatively on the upper, lower or on both flat sides of the tobacco rod act. In the latter case, a tobacco connecting bridge halfway between neighboring branches of the tobacco rod are formed.

For one of the above-mentioned embodiments of a tobacco cuboid can in the separating cuts between the neighboring Partial strands of dividers made of cardboard or the like are inserted, that are either already cut to the length of the subsets, or together with the partial strands on partial length get cut.

FIGS. 5-8 further embodiments of a smoking tobacco designed according to the invention, each in a perspective view;

9 and 10 schematically illustrated devices for producing smoking tobacco prepared according to the invention.

1 to 3 or 5 to 8 is smoking tobacco as Tobacco portion provided in the form of a tobacco cuboid 10, each tobacco cuboid in at least two, preferably six to eight subsets 11 is divided, each rod-like with a triangular (Fig. 4.1, 4.2), trapezoidal (Fig. 4.5), in particular rectangular, preferably square (Fig. 4.3, 4.4) cross section are formed, the length of each subset 11 being the length of the tobacco containment space corresponds to the cigarette to be produced. Of each subset 11 contains approximately that for a cigarette amount of tobacco required. In the illustrated embodiments the subsets 11 each have a lateral surface on, which is so permeable to air that it as such are not draftable and therefore not smokable. The individual subsets are namely none of the shown Embodiments surrounded with an envelope.

The division of the tobacco cuboid 10 into subsets can either manually by the consumer or by manufacturing respectively. In any case, the individual is separated Subsets of the tobacco cuboid through themselves in the longitudinal direction of the Tobacco cuboid extending separating cuts 12. These separating cuts 12 can either cover the entire height of the Tobacco cuboid 10, as in Fig. 1, Fig. 4.4, in the left Halves of Fig. 4.1, 4.2, in the right half of Fig. 4.5, 4.6, in the left halves of FIGS. 7 and 8, or only extend over a partial height, as in FIGS. 2, 3, 4.3, right half of Fig. 4.1, 4.2, in the left half of the Fig. 4.5, 4.6, in Fig. 5, Fig. 6 and the right half of the Fig. 7 is shown. In the latter case, the individual Parts connected by tobacco bars, the broken off in partial quantities when the tobacco cuboid was separated must be with appropriate dissolution of the inner Cohesion in these areas.

In the embodiment according to FIG. 3, the tobacco cuboid on the one hand, a length that is twice the length of the tobacco-receiving space corresponds to the cigarette to be produced. on the other hand can be the length as shown in Fig. 3 of the tobacco cuboid the length of the tobacco receiving space one Cigarette match, being the cuboid and accordingly the individual subsets are divided into at least two partial lengths which is easier handling when filling a Darning device or a simple wrapping with cigarette paper Allow (turning). Accordingly, is at half Length a transversely extending separating cut 13 is provided, in order to be able to break the subsets to length.

4.1 and 4.2, the separating cuts 12 are placed that subsets with a triangular cross section arise. Approximately trapezoidal cross sections of the subsets are made with the Separation cuts according to Fig. 4.5 obtained. In the embodiment a tobacco cuboid is divided according to FIG Longitudinal narrow sides are each convex, and in the the separating cuts 12 on a flat side, lower in Fig. 4.6 Flat side, each assigned groove-shaped recesses are to separate the individual subsets 11 from the tobacco cuboid to facilitate. The groove-shaped longitudinal recesses are identified in Fig. 4.6 with the reference number 14.

5 is characterized in that that around the tobacco cuboid 10 a sleeve 15 is laid around, the overlapping sides of the Sheathing 15 should be loosely one above the other. So that becomes a ensures greater transport security for the tobacco cuboid. The envelope 15 consists of non-consumable by smoking Material, e.g. made of paper laminated with aluminum.

In the embodiment according to FIG. 6 there are three tobacco cuboids 10 stacked to form a larger sales unit 16. In this way, a sales unit can be created which fits into a conventional "hinge-lid" package.

The embodiment according to FIG. 7 is characterized in that that in the separating cuts between adjacent subsets Stretch in longitudinal webs made of cardboard or the like. Material can be made. In any case, they should Longitudinal bars made of non-smoking material consist. According to the separating cuts 12, the Longitudinal bars across the entire height of the tobacco cuboid (left Half of Fig. 7) or only over part of the same (right half of Fig. 7) extend. In the illustrated Embodiment, the dividers 17 and 18 are each more integral Part of one over the lower flat side and the Envelope 19 or 20 extending on both longitudinal narrow sides. However, it is equally conceivable that the longitudinal webs 17, 18th formed independently of the base 19 or 20 are.

In the embodiment according to FIG. 8, the tobacco cuboid is 10 bordered by a packaging tray 21, which extends over the lower flat side and all narrow sides of the tobacco cuboid 10 extends. In the separating cuts between the individual Partial quantities are also dividers 17 and 18, respectively provided according to FIG. 7.

9 is a first possibility for the production of Shown tobacco cuboids of the type in question here. To this Purpose is a tobacco rod 22 with an approximately rectangular cross section continuously or intermittently on one spaced cutting or punching elements (Round knife 23) comprising tobacco separating device 24 passed (direction of conveyance arrow 25). The one shown here Embodiment is the cutting elements around rotary driven circular knives 23, the depth of cut T by appropriate displacement of the axis of rotation 25 relative to Tobacco strand 22 can be adjusted (see double arrow 26). A constant re-sharpening takes place during operation of the circular knife 23 through on both sides of the cutting edge 27 effective grinding wheels 28. Opposite the circular knives 23 a pressure device 29 is arranged, which against the Section of the circular knife 23 is effective. The circular knives 23 are also each a separator in the form of Splitting wedges or split plates penetrating the separating cuts 30 downstream, so that the tobacco in the area of Parting cuts remains separated.

The tobacco rod is divided into partial strands by the circular knives 23 divided. Then the partial strands are separated by an in Fig. 9 not shown, effective transversely to the conveying direction 25 Knife separated from tobacco rod 22. Then there is one Separation of the tobacco cuboids thus obtained and their Packaging.

In the embodiment according to FIG. 9, the rotary drives act Circular knife 23 from the lower side of the tobacco rod on this one. 10 in the embodiment the action from above. The procedure is otherwise the same to manufacture the partial strands that according to FIG. 9. In addition, however, behind the partition plates 30 in the individual separating cuts the above-mentioned dividers 17 or 18 inserted, wherein in the illustrated embodiment Separators 17 and 18 already cut to the length of the subsets are.

It should be mentioned that each tobacco cuboid has at least two, preferably comprises six to ten subsets.

The tobacco blend is made so that the individual Smoking portions give a taste that matches that a conventional factory-made cigarette equivalent. Above all, it is ensured that through the Pre-portioning the tobacco every cigarette equally tastes. The same applies to smoking or draft behavior and the smoke ingredients. The tobacco can be inside of the tobacco cuboid or the subsets more or less solid pressed together and / or with more or less inner Fixing agents or binders may be added.

Each subset should preferably be about 0.6 to 1.2 g tobacco contain.

In principle, it is also conceivable for the tobacco cuboid described to produce from individual tobacco sub-strands a tobacco rod corresponding to the tobacco rod 22 in FIGS. 9 and 10 are merged, then to subset length to be cut. The cohesion produced in this way Tobacco cuboids can then e.g. through a narrow-sided edging respectively.
