Abstract
The application concerns a smoking object in non-smokable form with a wrapping-material sheet and with a tobacco layer applied to one surface of the wrapping-material sheet, which object is converted into smokable object, in particular a cigarette, through rolling up or twisting by the consumer. The wrapping-material sheet can be of cigarette paper and is then rectangular, for example, and has no adhesive strips on its long sides. The sheet can also have the form of a parallelogram with corners not equal to 90° . The depth of the tobacco layer can be uniform and ap- proximately correspond to the radius of the smokable object obtained through rolling up, or the tobacco layering is wave-like when viewed from the side. The wrapping-material sheet can also be of tobacco foil, with a tobacco layer located on only one of the surfaces. The invention concerns further a packet that contains one or several of the smoking objects in non-smokable form, as well as a system for the user-production of the cigarettes that includes one of the smoking objects in non-smokable form and a small cigarette- paper sheet or a (filter-) cigarette-paper sleeve.
Description
~ 2183825 Smoking object, packet that contains one or several of the smoking objects, and system for the user-production of cigarettes The present invention concerns a smoking object in non-smokable form that includes a wrapping-material sheet made of cigarette paper, tobacco foil, or reconstituted tobacco, and a tobacco layer applied to one surface of the wrapping-material sheet, and concerns a packet that contains one or several of the smoking objects. The smoking object in non-smokable form can be converted by the consumer into a smokable smoking object, in particular a cigarette, by rolling up or twisting.
Various systems for the user-production of cigarettes are known.
For example, DE-C-34 07 461 describes so-called tobacco rolls, i.e. tobacco cartridges, that are not in themselves smokable, owing to their highly porous wrapping. The consumer can put these tobacco rolls into a filter-cigarette-paper sleeve and in this way obtain a finished cigarette.
A similar system is described in EP-A-0 632 967, which reveals a tobacco column whose wrapping projects beyond one end of the = 2183825 column and in this way forms a hollow space. The projection is so shaped that it is compressed by the pressure exerted by the mouth of a smoker, so that the product is smokable only after the insertion of a filter cartridge into the hollow space.
US-A-3 385 302 describes a small rectangular cigarette sheet that is covered on one side with a thin tobacco layer, with a narrow adhesive strip along a long side, and, if required, with filtering material, as well as a packet that contains several of these small covered cigarette sheets. The consumer can make a finished cigarette for himself by rolling up in a spiral manner the small covered sheet.
Known from GB-A-2 275 410 is a tobacco plate, covered on both sides with cigarette paper or tobacco foil, that can be processed into hollow tobacco cords. Various materials such as, for example, tobacco or plugs can be introduced into the hollow space. The user-production of cigarettes with the tobacco plates provided with wrapping material on both sides is not described.
Known from DE-A-41 13 252 is a cigarette formed from a zigzag-shaped, rolled-up tobacco plate with an outer wrapping. The cigarette has a higher bending resistance or bending strength than a conventional pressed tobacco rod. The user-production of the cigarette is not described.
Rolled filters are known from US-A-3 744 497 and JP 62-171 664.
The known systems for user-production of cigarettes have various disadvantages. Thus, the thin, porous wrapping of the tobacco cartridges of DE-C-34 07 461 is easily torn. Beyond that, the empty filter-cigarette-paper sleeve is delicate and is easily crushed or damaged prior to use. Also disadvantageous here - just as with the system in EP-A-O 632 967 - is the fact that the consumer must always combine two different components in order to be able to produce a finished cigarette. The cigarettes produced with the small sheets of US-A-3 385 302 have, by reason of the spiral rolling-up, a high cigarette-papes content. This detracts, on the one hand, from the taste of the cigarette, and on the other hand causes an additional main- and secondary-stream smoke.
The problem of the invention is therefore to make available a simple and, to the extent possible, one-piece system for user-production of smoking objects, in particular cigarettes, with a low filter-cigarette-paper content.
This problem is solved according to the invention by the fact that the wrapping-material sheet consists of cigarette paper and has the form of a parallelogram with corners unequal to 900 , and that the depth of the tobacco layer approximately corresponds to the radius of a smokable smoking object obtained through a rolling up of the smoking object or runs in a wave-like manner perpendicular to the long sides of the smoking object according to the invention.
The parallelogram form of the wrapping material sheet has the advantage that a finished, smokable smoking object can be formed very simply from this smoking object according to the invention, since the diagonally-adjacent, acute-angled corners of the smoking object according to the invention are grasped and twisted against each other. Preferably the angles of the acute-angled corners are 45-85 , especially 65-80 .
~ 21838,25 If the depth of the tobacco layer approximately corresponds to the radius of the finished, smokable smoking object or the length of the short side of the smoking object according to the invention approximately corresponds to the circumference of the circle of the finished, smokable smoking object, then the paper content is as low as possible. Yet the length of the short sides of the smoking object according to the invention is in most cases somewhat (e.g. 1-3 mm) greater than the circumference of the circle of the finished, smokable smoking object, since a narrow adhesive strip for closing is provided on the long sides of the smoking object according to the invention.
A wave-like cross-section of the short sides of the tobacco layer, i.e. the tobacco layer is applied with uneven depth perpendicular to the long sides of the smoking object according to the invention and has a hill-and-valley form, has the advantage that with the rolling up of the smoking object according to the invention the individual tobacco segments join together without the danger arising of a hollow-space formation. With this implementation example it is possible to lack the wrapping-material sheet and in spite of this to obtain a smokable product after the rolling up -and closing.
The wrapping material sheet can be formed out of conventional cigarette paper or even out of tobacco leaf (or tobacco leaves), tobacco foil, or reconstituted tobacco. This latter has the advantage that the entire smoking object then consists of tobacco material. A further-advantage of the use of tobacco foil as the wrapping material is that the tobacco covering can clearly be less thick than when cigarette paper is used. Also, a spiral rolling up is possible right away, since no additional main- or secondary-stream smoke is formed through the tobacco foil. Here too it is again preferable that the wrapping-material sheet have the form of a parallelogram with corners unequal to 90 , that the depth of the tobacco layer approximately corresponds to the radius of a ~ 2183825 smokable smoking object obtained through a rolling of the smoking object according to the invention or is formed wave-like perpendicular to the long sides of the smoking object according to the invention.
The smoking objects according to the invention are especially suitable for the user-production of cigarettes. Nevertheless, depending upon the wrapping material used and the tobacco (mixture) employed, besides cigarettes, cigarillos or cheroots, for example, can also be produced. The lengths of the long and short sides of the smoking object according to the invention are chosen in accordance with the product to be produced. Thus the long sides are, for example, 70-100 mm long and the short sides, for example, 10-35 mm. For thin cigarettes, so-called slim cigarettes, the short sides are preferably 10-20 mm long, for normal cigarettes preferably 20-28 mm.
Finished, smokable smoking objects can be easily formed from the smoking objects according to theinvention through rolling up (usually along their short sides) or twisting. These can, if need be, be inserted into known filter-cigarette-paper sleeves or wrapped with small cigarette-paper sheets. Suitable for this are, for example, smoking objects according to the invention that contain a wrapping-material sheet of cigarette paper whose long sides have no adhesive strip, and a tobacco layer applied to one surface of the wrapping-material sheet. Preferably, however, the smoking objects according to the invention have along an outer edge of one of their long sides a narrow (e.g. 2-4 mm wide) strip preferably coated with adhesive. The adhesives normally used for small cigarette-paper sheets can be employed for this. After the rolling up or twisting of the smoking objects, the product can be fixed through, for example, a moistening of the adhesive strip.
Alternatively, however, the smoking objects according to the invention can as well have on both long sides a narrow, tobacco-free strip, one or both of which are capable of adhering.
An uncoated strip, for example 2-3 cm wide, can be planned along an outer edge of one of the narrow sides of the wrapping-material sheet. The product produced from this then has a hollow space at one of its ends, which enables the consumer to put in a filter, together with, if required, further materials such as additives containing aromatic material, and so to vary the taste and strength of the cigarette.
Preferably, however, the wrapping-material sheet has on one of its narrow sides a strip with an applied filter-material layer or with a fixed filter plug, since these one-piece smoking objects make possible the simple production of a filter cigarette and the fixed filter-plug facilitates the rolling up of the smoking object according to the invention.
The conventional materials (cellulose, acetate, crepe paper, or activated carbon filters) can be employed as filter materials or filters. Preferably, however, the filter material or the filter plug consists of reconstituted tobacco or of a tobacco mixture usually used for cigarette production, since then the finished cigarette consists of tobacco materials to the greatest possible extent.
Reconstituted or homogenized tobacco is a mixture of tobacco materials, for example tobacco dust, very fine tobacco particles, stalks and leaves of tobacco plants, middle ribs of the leaves, which mixture, after being cut up, if required, by known methods (see, for example US-A-4 182 349 or EP-A-O 495 567), can be processed into tobacco foils.
~ 2183825 Hence, the tobacco foils as well as filters employed preferably consist exclusively of tobacco. If need be, however, they can also contain additives, for example cellulose or wood fibres, that however should not amount to more than 25% by weight of the tobacco foils or tobacco filters. A further additive material can be a binder, which can be a matter of a binder made from the middle ribs of the tobacco leaves. The additives here can be either added to the mixture that is processed into the tobacco =
foils or filters, or attached to the tobacco foil or filter. In general, all additives can be employed that can also be contained in conventional tobacco used for cigarette production.
Tobacco foil normally has a brownish colouring, corresponding to the natural colour of tobacco. Hence, for consumers who prefer a white product, the tobacco foil (and if need be also the filter) is bleached. Colour gradations are possible here, according to the intensity of the bleaching process. Preferably, bleaching leads to tobacco foils whose appearance largely corresponds to that of normal cigarette paper.
The invention further concerns a packet that contains one or several of the smoking objects according to the invention and, if need be, also filter plugs or filters separately, as well as a system for the user-production of cigarettes that comprises a smoking object according to the invention and a small cigarette-paper sheet, a cigarette-paper sleeve, or a filter cigarette-paper sleeve.
The smoking objects according to the invention can be produced in the following manner. First, the cigarette paper or the tobacco foil, both of which are produced in known manners, or the tobacco leaf is cut so as to correspond to the desired form of the smoking object.
= 2183825 Then the tobacco or the tobacco mixture is laid onto the wrapping material. Conventional cigarette tobacco, reconstituted or homogenized tobacco, or mixtures of these, for example, can be employed here as tobacco. The fixing of the tobacco to the wrapping material is achieved through application of a foam (for example by spraying on), which foam can contain, besides foaming materials, binders and, if need be, aromatic additive materials. An excellent foaming material is licorice powder. Plant extracts, pectin, maltodextrin, or gums, for example, can be used as binders.
Particularly preferable is gum arabic, which is an exceptional combination of a foaming material and a binder. The taste of the cigarette can be varied through the introduction of conventional aromatic substances, for example licorice, sugar, or cocoa extract (i.e. taste and release can be suited to the consumer's desires through the choice of the tobacco mixture and additive materials).
Subsequently, the tobacco layer is dried.
The depth of the tobacco layer can be determined through the amount of the tobacco applied at the start and with even distribution of the tobacco on the wrapping-material sheet amounts to, for example, 0.05 - 0.5 cm, in particular approximately 0.35 cm. If need be the depth can be adjusted before the drying by a light compressing. Normally the tobacco is evenly applied, so that a rectangular lateral cross-section of the tobacco layer results.
However, the upper long edge of the tobacco layer can also be beveled; the lateral cross-section is then trapezoidal. This facilitates the rolling up along the short sides and the closing of the smoking object according to the invention. Insofar as a hill-and-valley layering of tobacco is desired, this can can come about before the drying through a compressing of the appropriate spots, so that the depth of the tobacco layer varies from, for example, 0.05 - 0.1 cm for the depressions to 0.03 - 0.5 cm, in particular 0.35 cm, for the elevations.
If desired, an adhesive strip, e.g. a gum, can be attached in a conventional manner along one of the outside edges of the long sides, a strip of filter material along one of the outside edges of the short sides (for example through gluing on), or a filter plug before or after the application of the tobacco layer.
Preferably, the strip of filter material is reconstituted tobacco or a tobacco mixture attached in the same way as the tobacco layer.
Obviously, the cutting of the smoking article according to the invention can also take place after the layering with tobacco, etc., starting from a larger, covered sheet.
An implementation example of the invention is shown in the drawings and will be described in more detail in the following.

Fig. 1 shows an implementation example of a smoking object 10 according to the invention with a wrapping-material sheet 12 that is covered with a tobacco layer 14 and is provided with two short sides 16, 18 and two long sides 22, 24. On the outside edge 20 of the long side 22, a narrow strip of the wrapping-material sheet 12 is not covered with tobacco. Rather, an adhesive strip 36 is provided for here. A cigarette, for example, can be easily produced from the smoking object 10 through rolling up, a reopening being prevented by the adhering of the adhesive strip 36 to the outer side of the wrapping-material sheet 12. The tobacco layer 14 is here applied evenly, so that the lateral cross-section is rectangular.
Fig. 2 shows an additional implementation form of a smoking object 10 according to the invention. It is to be perceived that the wrapping-material sheet 12 is cut in the form of a parallelogram and that the angle of the acute-angled corners 21, 23 is approximately 80 . Fig. 2 shows further the tobacco layer 14, here shown hatched, as well as the adhesive strip 36.
Fig. 3 shows a cigarette 40 that can be produced from the smoking object 10 of Fig. 2. For this the acute-angled corners 21, 23 of the wrapping-material sheet are grasped and, when viewed along the double arrow of Fig. 2, the corner 23 is twisted clockwise and the corner 21 counterclockwise, as is shown in Fig. 2 by the two arrows. After the closing of the cigarette by means of the adhesive strip 36, one obtains the finished cigarette 40 of Fig. 3.
Shown in Fig. 4 is a further implementation example of the present invention. The smoking object 10 shows once again a wrapping- -material sheet 12 with a tobacco layer 14 affixed to it. A strip with filter material 30 is applied along an outside edge 28 of one narrow side 16 of the smoking object 10. As is to be gathered from Fig. 4, this filter-material strip 30 does not extend over the entire width of the smoking object 10, but rather ends, just as the tobacco layer 14 does, shortly before the outer edge 20 of the long side 22. The narrow strip remaining free along the outer edge 20 forms the adhesive strip 36 that is used to close the cigarette.
For the production of a cigarette, the smoking object 10 is rolled up, i.e. the consumer must move the two opposite long sides 22 and 24 towards each other. Fig. 5 shows an intermediate stage in the production of a finished cigarette 40 from the smoking object 10 of Fig. 4, the smoking object 10 being already rolled up into a cylinder. Fig. 5 shows, besides the wrapping material 12, the tobacco layer 14, and the filter-material layer 30, that the long side 24 lies just in front of the adhesive strip 36. In order to produce the finished cigarette, the consumer need yet only bring the long side 24 fully up to the adhesive strip 36, and the latter e.g. moisten, wrap around, and lightly press fast to the outer side of the wrapping-material sheet 12 along the long side 24, in , order to prevent the cigarette from opening up again. Finally, Fig. 5 shows that the outside of the wrapping-material sheet 12 can be marked in the region 25 of the filter-material strip 30, so that the filter end of the cigarette can be easily recognized by sight and has, for example, the appearanceof a conventional cover sheet.
~ 2183 ~ .825 Shown in Fig. 6 is an additional preferred smoking object 10 that has, in addition to the wrapping-material sheet 12 and the tobacco layer 14, an uncoated lateral strip 32 along the outside edge 28 and an adhesive strip 36 running along the outside edge 20 over the whole length of the long side 22. The cigarette produced from this smoking object 10 has a hollow space at one end, which space can, according to the desires of the consumer, be filled with e.g.
filter plugs or supplementary pieces giving off aromatic materials.
The smoking object 10 of Fig. 7 shows once again the wrapping material sheet 12, the tobacco layer 14, the uncoated strip 32, and the adhesive strip 36 running over the entire length of the long -side 22. In addition, a filter plug 34 is here provided for on the uncoated lateral strip 32, which plug is, for example, glued on.
Hence the smoker obtains a filter cigarette after rolling up the smoking object 10 of Fig. 7.
Figs. 8 through 12 show the preferred implementation form, that the tobacco layer is applied wave-like perpendicular to the long sides 22, 24, as well as a cigarette produced therefrom. First of all, shown in Fig. 8 is a lateral cross-section, for example along the short side 18. The tobacco layer 14 is applied to the wrapping-material sheet 12 in the form of waves, i.e. the tobacco layer has elevations 27 and depressions 29 and thus forms tobacco segments 26. Beyond that, the marginal regions along both long sides 22 and 24 of the smoking object 10 are free of tobacco.
The production of a cigarette 40 from the smoking object 10 of Fig. 8 is shown in Figs. 9 and 10, wherein it is to be perceived that the different tobacco segments 26 come together easily and that the peaks of the elevations 27 form the longitudinal axis of the resulting cigarette 40. Figs. 9 and 10 show further that the long sides 22 and 24 free of tobacco come to rest against each other. One or both of the marginal regions free of tobacco can be coated with an adhesive material, so that the cigarette is closed and forms a tongue 31. This tongue 31 has an adhesive coating on one of its outer sides, so that the tongue can be turned down and affixed to the finished cigarette 40, as shown in Fig. 11.
Various systems for the user-production of cigarettes are known.
For example, DE-C-34 07 461 describes so-called tobacco rolls, i.e. tobacco cartridges, that are not in themselves smokable, owing to their highly porous wrapping. The consumer can put these tobacco rolls into a filter-cigarette-paper sleeve and in this way obtain a finished cigarette.
A similar system is described in EP-A-0 632 967, which reveals a tobacco column whose wrapping projects beyond one end of the = 2183825 column and in this way forms a hollow space. The projection is so shaped that it is compressed by the pressure exerted by the mouth of a smoker, so that the product is smokable only after the insertion of a filter cartridge into the hollow space.
US-A-3 385 302 describes a small rectangular cigarette sheet that is covered on one side with a thin tobacco layer, with a narrow adhesive strip along a long side, and, if required, with filtering material, as well as a packet that contains several of these small covered cigarette sheets. The consumer can make a finished cigarette for himself by rolling up in a spiral manner the small covered sheet.
Known from GB-A-2 275 410 is a tobacco plate, covered on both sides with cigarette paper or tobacco foil, that can be processed into hollow tobacco cords. Various materials such as, for example, tobacco or plugs can be introduced into the hollow space. The user-production of cigarettes with the tobacco plates provided with wrapping material on both sides is not described.
Known from DE-A-41 13 252 is a cigarette formed from a zigzag-shaped, rolled-up tobacco plate with an outer wrapping. The cigarette has a higher bending resistance or bending strength than a conventional pressed tobacco rod. The user-production of the cigarette is not described.
Rolled filters are known from US-A-3 744 497 and JP 62-171 664.
The known systems for user-production of cigarettes have various disadvantages. Thus, the thin, porous wrapping of the tobacco cartridges of DE-C-34 07 461 is easily torn. Beyond that, the empty filter-cigarette-paper sleeve is delicate and is easily crushed or damaged prior to use. Also disadvantageous here - just as with the system in EP-A-O 632 967 - is the fact that the consumer must always combine two different components in order to be able to produce a finished cigarette. The cigarettes produced with the small sheets of US-A-3 385 302 have, by reason of the spiral rolling-up, a high cigarette-papes content. This detracts, on the one hand, from the taste of the cigarette, and on the other hand causes an additional main- and secondary-stream smoke.
The problem of the invention is therefore to make available a simple and, to the extent possible, one-piece system for user-production of smoking objects, in particular cigarettes, with a low filter-cigarette-paper content.
This problem is solved according to the invention by the fact that the wrapping-material sheet consists of cigarette paper and has the form of a parallelogram with corners unequal to 900 , and that the depth of the tobacco layer approximately corresponds to the radius of a smokable smoking object obtained through a rolling up of the smoking object or runs in a wave-like manner perpendicular to the long sides of the smoking object according to the invention.
The parallelogram form of the wrapping material sheet has the advantage that a finished, smokable smoking object can be formed very simply from this smoking object according to the invention, since the diagonally-adjacent, acute-angled corners of the smoking object according to the invention are grasped and twisted against each other. Preferably the angles of the acute-angled corners are 45-85 , especially 65-80 .
~ 21838,25 If the depth of the tobacco layer approximately corresponds to the radius of the finished, smokable smoking object or the length of the short side of the smoking object according to the invention approximately corresponds to the circumference of the circle of the finished, smokable smoking object, then the paper content is as low as possible. Yet the length of the short sides of the smoking object according to the invention is in most cases somewhat (e.g. 1-3 mm) greater than the circumference of the circle of the finished, smokable smoking object, since a narrow adhesive strip for closing is provided on the long sides of the smoking object according to the invention.
A wave-like cross-section of the short sides of the tobacco layer, i.e. the tobacco layer is applied with uneven depth perpendicular to the long sides of the smoking object according to the invention and has a hill-and-valley form, has the advantage that with the rolling up of the smoking object according to the invention the individual tobacco segments join together without the danger arising of a hollow-space formation. With this implementation example it is possible to lack the wrapping-material sheet and in spite of this to obtain a smokable product after the rolling up -and closing.
The wrapping material sheet can be formed out of conventional cigarette paper or even out of tobacco leaf (or tobacco leaves), tobacco foil, or reconstituted tobacco. This latter has the advantage that the entire smoking object then consists of tobacco material. A further-advantage of the use of tobacco foil as the wrapping material is that the tobacco covering can clearly be less thick than when cigarette paper is used. Also, a spiral rolling up is possible right away, since no additional main- or secondary-stream smoke is formed through the tobacco foil. Here too it is again preferable that the wrapping-material sheet have the form of a parallelogram with corners unequal to 90 , that the depth of the tobacco layer approximately corresponds to the radius of a ~ 2183825 smokable smoking object obtained through a rolling of the smoking object according to the invention or is formed wave-like perpendicular to the long sides of the smoking object according to the invention.
The smoking objects according to the invention are especially suitable for the user-production of cigarettes. Nevertheless, depending upon the wrapping material used and the tobacco (mixture) employed, besides cigarettes, cigarillos or cheroots, for example, can also be produced. The lengths of the long and short sides of the smoking object according to the invention are chosen in accordance with the product to be produced. Thus the long sides are, for example, 70-100 mm long and the short sides, for example, 10-35 mm. For thin cigarettes, so-called slim cigarettes, the short sides are preferably 10-20 mm long, for normal cigarettes preferably 20-28 mm.
Finished, smokable smoking objects can be easily formed from the smoking objects according to theinvention through rolling up (usually along their short sides) or twisting. These can, if need be, be inserted into known filter-cigarette-paper sleeves or wrapped with small cigarette-paper sheets. Suitable for this are, for example, smoking objects according to the invention that contain a wrapping-material sheet of cigarette paper whose long sides have no adhesive strip, and a tobacco layer applied to one surface of the wrapping-material sheet. Preferably, however, the smoking objects according to the invention have along an outer edge of one of their long sides a narrow (e.g. 2-4 mm wide) strip preferably coated with adhesive. The adhesives normally used for small cigarette-paper sheets can be employed for this. After the rolling up or twisting of the smoking objects, the product can be fixed through, for example, a moistening of the adhesive strip.
Alternatively, however, the smoking objects according to the invention can as well have on both long sides a narrow, tobacco-free strip, one or both of which are capable of adhering.
An uncoated strip, for example 2-3 cm wide, can be planned along an outer edge of one of the narrow sides of the wrapping-material sheet. The product produced from this then has a hollow space at one of its ends, which enables the consumer to put in a filter, together with, if required, further materials such as additives containing aromatic material, and so to vary the taste and strength of the cigarette.
Preferably, however, the wrapping-material sheet has on one of its narrow sides a strip with an applied filter-material layer or with a fixed filter plug, since these one-piece smoking objects make possible the simple production of a filter cigarette and the fixed filter-plug facilitates the rolling up of the smoking object according to the invention.
The conventional materials (cellulose, acetate, crepe paper, or activated carbon filters) can be employed as filter materials or filters. Preferably, however, the filter material or the filter plug consists of reconstituted tobacco or of a tobacco mixture usually used for cigarette production, since then the finished cigarette consists of tobacco materials to the greatest possible extent.
Reconstituted or homogenized tobacco is a mixture of tobacco materials, for example tobacco dust, very fine tobacco particles, stalks and leaves of tobacco plants, middle ribs of the leaves, which mixture, after being cut up, if required, by known methods (see, for example US-A-4 182 349 or EP-A-O 495 567), can be processed into tobacco foils.
~ 2183825 Hence, the tobacco foils as well as filters employed preferably consist exclusively of tobacco. If need be, however, they can also contain additives, for example cellulose or wood fibres, that however should not amount to more than 25% by weight of the tobacco foils or tobacco filters. A further additive material can be a binder, which can be a matter of a binder made from the middle ribs of the tobacco leaves. The additives here can be either added to the mixture that is processed into the tobacco =
foils or filters, or attached to the tobacco foil or filter. In general, all additives can be employed that can also be contained in conventional tobacco used for cigarette production.
Tobacco foil normally has a brownish colouring, corresponding to the natural colour of tobacco. Hence, for consumers who prefer a white product, the tobacco foil (and if need be also the filter) is bleached. Colour gradations are possible here, according to the intensity of the bleaching process. Preferably, bleaching leads to tobacco foils whose appearance largely corresponds to that of normal cigarette paper.
The invention further concerns a packet that contains one or several of the smoking objects according to the invention and, if need be, also filter plugs or filters separately, as well as a system for the user-production of cigarettes that comprises a smoking object according to the invention and a small cigarette-paper sheet, a cigarette-paper sleeve, or a filter cigarette-paper sleeve.
The smoking objects according to the invention can be produced in the following manner. First, the cigarette paper or the tobacco foil, both of which are produced in known manners, or the tobacco leaf is cut so as to correspond to the desired form of the smoking object.
= 2183825 Then the tobacco or the tobacco mixture is laid onto the wrapping material. Conventional cigarette tobacco, reconstituted or homogenized tobacco, or mixtures of these, for example, can be employed here as tobacco. The fixing of the tobacco to the wrapping material is achieved through application of a foam (for example by spraying on), which foam can contain, besides foaming materials, binders and, if need be, aromatic additive materials. An excellent foaming material is licorice powder. Plant extracts, pectin, maltodextrin, or gums, for example, can be used as binders.
Particularly preferable is gum arabic, which is an exceptional combination of a foaming material and a binder. The taste of the cigarette can be varied through the introduction of conventional aromatic substances, for example licorice, sugar, or cocoa extract (i.e. taste and release can be suited to the consumer's desires through the choice of the tobacco mixture and additive materials).
Subsequently, the tobacco layer is dried.
The depth of the tobacco layer can be determined through the amount of the tobacco applied at the start and with even distribution of the tobacco on the wrapping-material sheet amounts to, for example, 0.05 - 0.5 cm, in particular approximately 0.35 cm. If need be the depth can be adjusted before the drying by a light compressing. Normally the tobacco is evenly applied, so that a rectangular lateral cross-section of the tobacco layer results.
However, the upper long edge of the tobacco layer can also be beveled; the lateral cross-section is then trapezoidal. This facilitates the rolling up along the short sides and the closing of the smoking object according to the invention. Insofar as a hill-and-valley layering of tobacco is desired, this can can come about before the drying through a compressing of the appropriate spots, so that the depth of the tobacco layer varies from, for example, 0.05 - 0.1 cm for the depressions to 0.03 - 0.5 cm, in particular 0.35 cm, for the elevations.
If desired, an adhesive strip, e.g. a gum, can be attached in a conventional manner along one of the outside edges of the long sides, a strip of filter material along one of the outside edges of the short sides (for example through gluing on), or a filter plug before or after the application of the tobacco layer.
Preferably, the strip of filter material is reconstituted tobacco or a tobacco mixture attached in the same way as the tobacco layer.
Obviously, the cutting of the smoking article according to the invention can also take place after the layering with tobacco, etc., starting from a larger, covered sheet.
An implementation example of the invention is shown in the drawings and will be described in more detail in the following.
Shown are:
Fig. 1: a smoking object according to the invention;
Fig. 2: an additional smoking object according to the invention in top view in the form of a parallelogram with corners unequal to 90 ;
Fig. 3: a cigarette produced from the smoking object of Fig. 2;

Fig. 9: an intermediate stage in the production of a cigarette from the smoking object according to Fig. 8;
Fig. 10: the intermediate stage according to Fig. 9 from the f ront ;
Fig. 11: the finished cigarette produced from the smoking object according to Fig. 8, in front view.
Fig. 1 shows an implementation example of a smoking object 10 according to the invention with a wrapping-material sheet 12 that is covered with a tobacco layer 14 and is provided with two short sides 16, 18 and two long sides 22, 24. On the outside edge 20 of the long side 22, a narrow strip of the wrapping-material sheet 12 is not covered with tobacco. Rather, an adhesive strip 36 is provided for here. A cigarette, for example, can be easily produced from the smoking object 10 through rolling up, a reopening being prevented by the adhering of the adhesive strip 36 to the outer side of the wrapping-material sheet 12. The tobacco layer 14 is here applied evenly, so that the lateral cross-section is rectangular.
Fig. 2 shows an additional implementation form of a smoking object 10 according to the invention. It is to be perceived that the wrapping-material sheet 12 is cut in the form of a parallelogram and that the angle of the acute-angled corners 21, 23 is approximately 80 . Fig. 2 shows further the tobacco layer 14, here shown hatched, as well as the adhesive strip 36.
Fig. 3 shows a cigarette 40 that can be produced from the smoking object 10 of Fig. 2. For this the acute-angled corners 21, 23 of the wrapping-material sheet are grasped and, when viewed along the double arrow of Fig. 2, the corner 23 is twisted clockwise and the corner 21 counterclockwise, as is shown in Fig. 2 by the two arrows. After the closing of the cigarette by means of the adhesive strip 36, one obtains the finished cigarette 40 of Fig. 3.
Shown in Fig. 4 is a further implementation example of the present invention. The smoking object 10 shows once again a wrapping- -material sheet 12 with a tobacco layer 14 affixed to it. A strip with filter material 30 is applied along an outside edge 28 of one narrow side 16 of the smoking object 10. As is to be gathered from Fig. 4, this filter-material strip 30 does not extend over the entire width of the smoking object 10, but rather ends, just as the tobacco layer 14 does, shortly before the outer edge 20 of the long side 22. The narrow strip remaining free along the outer edge 20 forms the adhesive strip 36 that is used to close the cigarette.
For the production of a cigarette, the smoking object 10 is rolled up, i.e. the consumer must move the two opposite long sides 22 and 24 towards each other. Fig. 5 shows an intermediate stage in the production of a finished cigarette 40 from the smoking object 10 of Fig. 4, the smoking object 10 being already rolled up into a cylinder. Fig. 5 shows, besides the wrapping material 12, the tobacco layer 14, and the filter-material layer 30, that the long side 24 lies just in front of the adhesive strip 36. In order to produce the finished cigarette, the consumer need yet only bring the long side 24 fully up to the adhesive strip 36, and the latter e.g. moisten, wrap around, and lightly press fast to the outer side of the wrapping-material sheet 12 along the long side 24, in , order to prevent the cigarette from opening up again. Finally, Fig. 5 shows that the outside of the wrapping-material sheet 12 can be marked in the region 25 of the filter-material strip 30, so that the filter end of the cigarette can be easily recognized by sight and has, for example, the appearanceof a conventional cover sheet.
~ 2183 ~ .825 Shown in Fig. 6 is an additional preferred smoking object 10 that has, in addition to the wrapping-material sheet 12 and the tobacco layer 14, an uncoated lateral strip 32 along the outside edge 28 and an adhesive strip 36 running along the outside edge 20 over the whole length of the long side 22. The cigarette produced from this smoking object 10 has a hollow space at one end, which space can, according to the desires of the consumer, be filled with e.g.
filter plugs or supplementary pieces giving off aromatic materials.
The smoking object 10 of Fig. 7 shows once again the wrapping material sheet 12, the tobacco layer 14, the uncoated strip 32, and the adhesive strip 36 running over the entire length of the long -side 22. In addition, a filter plug 34 is here provided for on the uncoated lateral strip 32, which plug is, for example, glued on.
Hence the smoker obtains a filter cigarette after rolling up the smoking object 10 of Fig. 7.
Figs. 8 through 12 show the preferred implementation form, that the tobacco layer is applied wave-like perpendicular to the long sides 22, 24, as well as a cigarette produced therefrom. First of all, shown in Fig. 8 is a lateral cross-section, for example along the short side 18. The tobacco layer 14 is applied to the wrapping-material sheet 12 in the form of waves, i.e. the tobacco layer has elevations 27 and depressions 29 and thus forms tobacco segments 26. Beyond that, the marginal regions along both long sides 22 and 24 of the smoking object 10 are free of tobacco.
The production of a cigarette 40 from the smoking object 10 of Fig. 8 is shown in Figs. 9 and 10, wherein it is to be perceived that the different tobacco segments 26 come together easily and that the peaks of the elevations 27 form the longitudinal axis of the resulting cigarette 40. Figs. 9 and 10 show further that the long sides 22 and 24 free of tobacco come to rest against each other. One or both of the marginal regions free of tobacco can be coated with an adhesive material, so that the cigarette is closed and forms a tongue 31. This tongue 31 has an adhesive coating on one of its outer sides, so that the tongue can be turned down and affixed to the finished cigarette 40, as shown in Fig. 11.
