Description
Attorney file reference: 71 004 XV
Applicant: British American Tobacco (Germany) GmbH
Tobacco packet and system comprising tobacco packet and filling machine The invention relates to a tobacco packet as well as a system comprising a tobacco packet and a filling machine. Specifically, this invention relates to the field of self-produced smoking articles, also known as Make-Your-Own (MYO) smoking articles (also referred to as MYO smoking articles hereafter). Such smoking articles are usually cigarettes or filter cigarettes. Such MYO smoking articles are made by the consumer himself, who takes a portion of what is usually loose tobacco by hand, distributes it as homogeneously as possible in the housing compartment of a filling device (filling machine) and then converts it into a pre-prepared filter cigarette. The cigarettes produced as a result necessarily vary considerably from the quality of a factory cigarette; packing densities fluctuate and the quantities of tobacco across the cigarette length vary with each cigarette. In view of the fact that the tobacco has to be manually handled, it is also not made with the same level of hygiene and there is no avoiding the loss of tobacco crumbs.
Document DE 20 2005 012 273 U1 discloses an MYO filling device, on which a rim is provided across the tobacco housing region, the purpose of which is to prevent tobacco crumbs from falling out.
Patent specification DE 34 15 391 Al discloses a tobacco pouch on which an aid for rolling cigarettes is fitted. A filling machine is not used in this instance.
Patent specification DE 33 12 433 Al discloses a device which is immersed in the tobacco supply when making a cigarette and takes out the tobacco itself.
A tobacco filling device with two supply containers which can be fitted on the filling device is known from patent specification DE 33 19 195 Al. One of the supply containers is a tobacco holder, which can be closed off with the aid of the closed bottom face of the filling device.
One objective of this invention is to propose a tobacco packet which ensures that tobacco can be transferred to a tobacco filling machine in the most efficient manner to enable high quality MYO smoking articles or cigarettes to be produced. The system proposed by the invention also comprises a tobacco packet and a filling machine and is designed for this purpose.
This objective is achieved on the basis of a tobacco packet as defined in claim 1 and a system comprising a tobacco packet and filling machine as defined in claim 23. The dependent claims define preferred embodiments of the invention.
The advantages of the solution proposed by the invention are obtained by providing the adapter for fitting the tobacco packet on a complementary adapter of the tobacco filling opening or tobacco housing compartment of a filling machine. In other words, the invention enables a commercially sold, sealed tobacco packet with tobacco contained in it to be directly connected to a filling machine without the need for further aids, and this is possible due to the fact that the adapter is provided. The tobacco can therefore be transferred to the filling machine in portions and homogeneously distributed without coming into contact with the hand, thereby enabling a high quality smoking product to be produced under hygienic conditions. Since the adapter may be provided in designs which are different but also match a specific filling machine, a number of design options are conceivable and the invention makes for simple and rapid manipulation with reproducible results.
The tobacco packet may be made from a plastic or foil material, a cardboard material or a coated cardboard material and may be of a quadratic or packet shape. It may be rigid or flexible and is preferably a closed packet which can be supplied as a closed unit together with the adapter, and in this format is practical to sell and handle.

Tobacco packet and system comprising tobacco packet and filling machine The invention relates to a tobacco packet as well as a system comprising a tobacco packet and a filling machine. Specifically, this invention relates to the field of self-produced smoking articles, also known as Make-Your-Own (MYO) smoking articles (also referred to as MYO smoking articles hereafter). Such smoking articles are usually cigarettes or filter cigarettes. Such MYO smoking articles are made by the consumer himself, who takes a portion of what is usually loose tobacco by hand, distributes it as homogeneously as possible in the housing compartment of a filling device (filling machine) and then converts it into a pre-prepared filter cigarette.

In view of the fact that the tobacco has to be manually handled, it is also not made with the same level of hygiene and there is no avoiding the loss of tobacco crumbs.
Document DE 20 2005 012 273 U1 discloses an MYO filling device, on which a rim is provided across the tobacco housing region, the purpose of which is to prevent tobacco crumbs from falling out.
Patent specification DE 34 15 391 Al discloses a tobacco pouch on which an aid for rolling cigarettes is fitted. A filling machine is not used in this instance.
Patent specification DE 33 12 433 Al discloses a device which is immersed in the tobacco supply when making a cigarette and takes out the tobacco itself.
A tobacco filling device with two supply containers which can be fitted on the filling device is known from patent specification DE 33 19 195 Al. One of the supply containers is a tobacco holder, which can be closed off with the aid of the closed bottom face of the filling device.
One objective of this invention is to propose a tobacco packet which ensures that tobacco can be transferred to a tobacco filling machine in the most efficient manner to enable high quality MYO smoking articles or cigarettes to be produced. The system proposed by the invention also comprises a tobacco packet and a filling machine and is designed for this purpose.
This objective is achieved on the basis of a tobacco packet as defined in claim 1 and a system comprising a tobacco packet and filling machine as defined in claim 23. The dependent claims define preferred embodiments of the invention.
The advantages of the solution proposed by the invention are obtained by providing the adapter for fitting the tobacco packet on a complementary adapter of the tobacco filling opening or tobacco housing compartment of a filling machine. In other words, the invention enables a commercially sold, sealed tobacco packet with tobacco contained in it to be directly connected to a filling machine without the need for further aids, and this is possible due to the fact that the adapter is provided. The tobacco can therefore be transferred to the filling machine in portions and homogeneously distributed without coming into contact with the hand, thereby enabling a high quality smoking product to be produced under hygienic conditions. Since the adapter may be provided in designs which are different but also match a specific filling machine, a number of design options are conceivable and the invention makes for simple and rapid manipulation with reproducible results.
The tobacco packet may be made from a plastic or foil material, a cardboard material or a coated cardboard material and may be of a quadratic or packet shape. It may be rigid or flexible and is preferably a closed packet which can be supplied as a closed unit together with the adapter, and in this format is practical to sell and handle.
In one embodiment, a peel-off closure may be provided on its tobacco dispensing opening, in particular a closure providing the packet with an air-tight seal, which ensures that the tobacco remains fresh. The closure may be provided in the form of a disposable closure or alternatively a closure which can be resealed.
Preferably, it essentially forms the closure of the packet on the side incorporating the tobacco dispensing opening. In a preferred embodiment, the closure has an opening aid, in particular at least one of the following opening aids:
- a perforation;
- a grip portion which projects out from the tobacco dispensing opening or is detachably attached to the packet;
- a means acting on an opening means of a filling machine.
Within the context of the invention, it is possible to design the closure so that it can be pulled off essentially parallel with the face of the tobacco dispensing opening, in particular by pulling the closure out of a guide on the tobacco dispensing opening or by severing it or tearing it off at its peripheral regions. In this respect, it is of practical advantage if the closure is designed so that it is not opened until after the tobacco packet has been fitted on the filling machine because in this case, it can be practically pulled out from the side. In one embodiment of the invention, another air-tight seal may be provided above the closure, in particular on the tobacco dispensing opening, especially if a perforated closure is used. The seal may also extend across the entire packet and will reliably ensure that the tobacco contained in the tobacco packet remains fresh under all circumstances.
As for the adapter on the tobacco packet proposed by the invention, it may essentially comprise the edge of the tobacco dispensing opening, or may essentially comprise the edge of the tobacco dispensing opening except for the region from which the closure can be removed, or may essentially comprise the edge of the tobacco dispensing opening at discrete retaining points or retaining lines. The key thing is that the adapter affords a perfect hold and permits a correct disposition of the tobacco packet.
Preferably, it essentially forms the closure of the packet on the side incorporating the tobacco dispensing opening. In a preferred embodiment, the closure has an opening aid, in particular at least one of the following opening aids:
- a perforation;
- a grip portion which projects out from the tobacco dispensing opening or is detachably attached to the packet;
- a means acting on an opening means of a filling machine.

The seal may also extend across the entire packet and will reliably ensure that the tobacco contained in the tobacco packet remains fresh under all circumstances.
As for the adapter on the tobacco packet proposed by the invention, it may essentially comprise the edge of the tobacco dispensing opening, or may essentially comprise the edge of the tobacco dispensing opening except for the region from which the closure can be removed, or may essentially comprise the edge of the tobacco dispensing opening at discrete retaining points or retaining lines. The key thing is that the adapter affords a perfect hold and permits a correct disposition of the tobacco packet.
The adapter may be a connecting component of a releasable connection and one of the following connecting components may be used in particular:
- a sliding guide component;
- a web, which can be accommodated in a track or a groove;
- a track or groove which is able to accommodate a web;
- a catch means;
- a releasable adhesive means;
- a tilting catch closure.
Said web may also be profiled, for example may have a T-shaped contour, in which case the track would naturally be designed accordingly and complement it.
In order to guarantee the correct disposition of the adapter on a filling machine in terms of position, the adapter is preferably provided with a positioning aid, in particular a positioning-engaging component, such as a meshing contact, a stop or a joint or a hinge component. Other options are to provide the adapter with an acting means or contour for acting on a displacement mechanism, which will be explained in more detail below.
In one special embodiment, the adapter forms a part of the packet, in particular an integral part of the packet, especially a part of a compact packet which folds open.
This being the case, the fold-out part may be the rest of a packet side of the packet which can be cut open and lies above the tobacco dispensing opening. This design is of particular advantage because the packet can initially be kept very compact for retail purposes and the adapter is not formed until the time of use.
The adapter and closure may also be a unit, in particular an integral unit, for example if the adapter constitutes a part of the closure or can be formed from a part of the closure, in which case a part left behind after opening the closure may be used as the adapter.
- a sliding guide component;
- a web, which can be accommodated in a track or a groove;
- a track or groove which is able to accommodate a web;
- a catch means;
- a releasable adhesive means;
- a tilting catch closure.

The adapter and closure may also be a unit, in particular an integral unit, for example if the adapter constitutes a part of the closure or can be formed from a part of the closure, in which case a part left behind after opening the closure may be used as the adapter.
In another embodiment of the tobacco packet proposed by the invention, a feeder element is provided on it or in it in order to push the tobacco forward in the direction of the tobacco dispensing opening, and the feeder element may extend round the rear part of the tobacco remote from the tobacco dispensing opening and for example may be designed as a slide which can be taken hold of from outside the packet, for example. In another possible embodiment, the feeder element has a flat web element which extends at least partially round the tobacco and a gripping tab on the tobacco dispensing opening or in the region of the tobacco dispensing opening projecting out from the packet. By pulling on the gripping tab, the tobacco is conveyed to the dispensing opening, and markings may be provided on the web element indicating the quantity of tobacco which has been removed or is still left, so that the user advantageously knows how many more cigarettes he can still make.
The tobacco packet-filling machine system proposed by the invention comprises a tobacco packet based on one of the different embodiments described above, as well as a cigarette filling machine, which has a complementary co-operating adapter piece for the adapter of the tobacco packet on the tobacco filling opening or the tobacco housing compartment.
For the purpose of the invention, the tobacco packet described above is a product which can be sold separately and its adapter enables it to be fitted on a complementary filling machine and thus already offers optimised features during use. In conjunction with the cigarette filling machine described, the invention offers further advantages and the system as a whole naturally also offers the same advantages as those described above in connection with the tobacco packet.
In a preferred embodiment, the adapter complementary part engages the adapter so that an essentially closed connection is established between the tobacco packet and the tobacco filling opening or the tobacco housing compartment, preventing any tobacco from falling out.

In a preferred embodiment, the adapter complementary part engages the adapter so that an essentially closed connection is established between the tobacco packet and the tobacco filling opening or the tobacco housing compartment, preventing any tobacco from falling out.
The process of opening the closure can also be optimised by an appropriate design if the adapter complementary part is provided with a blade mechanism for the closure of the packet, in which case the blade mechanism opens or pulls off the closure or renders it removable specifically when the adapter and adapter complementary part are connected. Embodiments of the invention are designed so that the adapter complementary part has a complementary co-operating part for the following elements of the packet:
- the sliding guide component;
- the web, which can be accommodated in a track or a groove;
- the track or groove, which is able to accommodate a web;
- the catch means;
- the releasable adhesive means;
- the positioning aid;
- the tilting catch closure.
As mentioned above, in a preferred embodiment, the adapter has a acting means or contour for acting on a displacement mechanism. In a complementary arrangement, the filling machine or the adapter complementary part may have a displacement mechanism, which can be moved into engagement with this acting means or this contour of the adapter in order to position the tobacco packet on the filling machine. This positioning can be achieved due to the fact that the packet is placed on the filling machine by means of the adapter and transferred by the displacement mechanism to its final position from which the tobacco is dispensed.
Generally speaking, the tobacco packet may be placed over the tobacco filling opening by means of the adapter and the adapter complementary part so that the tobacco is able to drop into the tobacco compartment of the filling machine under the effect of gravitational force. However, the tobacco packet can also be placed on the tobacco filling opening in a different position, for example at the side, in which case the feeder element mentioned above may be used as a means of conveying the tobacco towards the dispensing opening. In principle, an arrangement mounted from underneath would also be possible.

In principle, an arrangement mounted from underneath would also be possible.
In terms of shape, the adapter and the adapter complementary part are preferably designed so that only one adapter shape fits one adapter complementary part shape and establishes an active connection. This results in an optimum fit between packet and filling machine enabling optimum smoking articles to be produced.
As for the tobacco used, which is accommodated in a packet proposed by the invention, there is a practical distinction between two groups of application concepts, although the invention is not limited to these. These two groups are packets and systems for loose tobacco on the one hand and packets and systems for tobacco units, which will be referred to as tobacco blocks hereafter, on the other hand.
The loose tobacco to which this application relates should be construed as meaning tobacco with which a packet container has been loosely filled and which has not been compacted due to compression under its own weight, either before or after the packaging process.
A tobacco block, on the other hand, specifically has a homogeneous tobacco density which is higher than the loosely packed density of loose tobacco but is not significantly different from that of the finished cigarette, and in particular the tobacco density of the tobacco block is no higher than twice that of the finished cigarette and no lower than half that of the finished cigarette. The tobacco block used is one with a tobacco density which is close to that of the finished cigarette.
The tobacco block is advantageously of a height and width corresponding to the dimensions of the finished cigarette, i.e. the height of the tobacco block corresponds to the diameter, and the width of the tobacco block corresponds to the length of the tobacco stick of the finished cigarette. Given that the tobacco density of the tobacco block and the finished cigarette are virtually identical, the corresponding dimensions are also therefore virtually identical. However, if the tobacco density of the tobacco block lies above or below that of the finished cigarette, this is compensated by the corresponding adaptations of the height or width of the tobacco block to enable a cigarette of high quality to be produced. The length of the tobacco block corresponds to the number of portions of the multi-portion tobacco quantity in the tobacco block. By preference, the length is selected so that the tobacco portions contained in the tobacco block constitute a whole number. In particular, the number of tobacco portions should be greater than 5.
The tobacco block has a homogeneous tobacco density, which preferably does not assume any predefined structure. In particular, there are no stick-shaped pre-prepared portions. However, it would be conceivable for the tobacco block to predefine perforations in the tobacco at the corresponding parts of the length of the tobacco block, without the tobacco block being sub-divided. Such perforations may be made by various methods. In particular, it would be conceivable to use blades, cutting discs or a water-jet cutting process. The purpose of these perforations is to facilitate the separation of a tobacco portion from the rest of the tobacco block.
By preference, the tobacco block should hold together on the basis of inherent forces. In the case of tobacco cuts with long fibres, this is achieved quite simply on the basis of the length of the fibres. In the case of tobacco cuts with short fibres, this can be achieved by adapting the casing materials. If necessary, the surface of the tobacco block may also be treated accordingly, in particular sprayed.
The invention will be described in more detail below on the basis of different embodiments and with reference to the appended drawings. It may incorporate all the features described herein, both individually and in any practical combination, and may also be defined as a method or a use. Of the drawings:

Examples of embodiments preferably designed for use with loose tobacco.
Figure 1 illustrates an embodiment based on a first example for a system with loose tobacco. Figure 1 a schematically illustrates a filling machine 1; only the part of the guide 5 which constitutes an adapter on the filling machine is of importance as far as the invention is concerned. Illustrated in front of it is a tobacco packet 3.
Shown in the filling machine 1 is the guide 5, which is disposed directly above a tobacco filling opening or the tobacco housing compartment 9. The tobacco packet 3 is provided with a guide complementary piece 7 on its bottom face, which forms an adapter on the tobacco packet. The guide 5 and guide complementary piece 7 are designed so that they fit one another exactly. In this embodiment, both are cut in a converging pattern. When the tobacco packet 3 is pushed into the filling machine 1 in the direction indicated by the arrow, it assumes the desired position above the tobacco filling space (tobacco housing compartment 9) precisely as it reaches the end position, as illustrated in 1 b. Disposed on the bottom face of the tobacco packet 3 is a peel-off closure 11, which seals the contents off from the ambient environment. In order to render the tobacco in the tobacco packet 3 accessible for use in the filling machine 1, the peel-off closure 11 is removed, as illustrated in Figure 1 c.
Figure 2 illustrates an example of an embodiment of the tobacco packet 3 from Figure 1 in detail. Specifically illustrated is an option whereby the guide complementary piece 7 is designed so that the tobacco packet 3 as a whole is of a basic quadratic shape, which is practical in terms of transporting such tobacco packets.
To provide a clearer illustration, the bottom face from Figure 1 is now shown at the top. Provided on a narrow face is a fold-out portion 13, which can be folded out and serves as a gripping portion or gripping tab, enabling a protective strip 15 to be pulled off. As a result, two fold-out tabs 17a and 17b may be seen, which can be folded out and which, together with the thickness of the tobacco packet 3, constitute the guide complementary piece 7 for the guide 5. The peel-off closure 11 may be seen underneath the fold-out tabs 17a and 17b.
Figure 3 provides an even more detailed illustration in three steps a-c of how the fold-out tabs 17 a and b are made ready by pulling off the protective strip 15, which causes the perforations to break open.
Figure 4 shows a longitudinal section through the tobacco packet 3 and illustrates in steps a-d how the peel-off closure 11 is removed from the tobacco packet 3 and the loose tobacco 19 thus released from the tobacco packet 3.
Amongst other things, the tobacco packet 3 based on this embodiment may be made from both a plastic or foil material and cardboard. However, other materials would also be conceivable within the meaning of the invention, e.g. coated cardboard, for example of the type used for drinks packaging.
Figure 5 provides a total of five diagrams (a-e) illustrating another embodiment of the invention for loose tobacco. The tobacco packet 3 is illustrated above a filling machine 1. The tobacco packet 3 has not actually been pushed into the filling machine 1 but has merely been placed above a guide 5. The adapter connection in this embodiment is based on a tilting axis 21. Accordingly, the bottom face of the tobacco packet 3 is provided with a guide complementary piece 7 to permit the tilting action about the tilting axis 21. As illustrated in Figure 5 b, specifically showing a detail on a larger scale, the tobacco packet 3 can be tilted downwards and is preferably retained in a bottom end position due to an automatically snap-fitting closure mechanism 23 (latched closure). A similar closure mechanism is provided on the co-operating face of the tobacco packet 3. In Figure 5c, the tobacco packet 3 has been tilted further downwards and blades sever the seal of the tobacco packet 3 due to the tilting movement. This can be seen even more clearly in Figure 5d, which is a diagram in section rotated by 90 . Figure 5e illustrates how the seal 27 is pulled out and the loose tobacco thus released.
Figure 6 illustrates an exemplary embodiment of the tobacco packet 3 from Figure 5. The tobacco packet 3 is preferably made with a plastic body in which the complementary pieces 29 for the closure mechanism 23 are already provided. The seal 27 may be seen on the bottom face in Figure 6b, which can be cut by the blades 25 along what are indicated as broken lines (Figure 5d) and then pulled off.
Figure 7 shows individual diagrams (a-d) illustrating an example of how the loose tobacco 19 can be subsequently prepared in the case of this embodiment. The same applies to the embodiment illustrated in Figures 1-4.
The tobacco packet 3 connected to the filling machine 1 (diagram 7a) has already been opened and is ready to dispense the loose tobacco 19. When the slide 31 is operated, a tobacco housing compartment 9 is released, so that the state illustrated in diagram 7b is assumed. The loose tobacco 19 drops, essentially conveyed by its own weight, into the tobacco housing compartment 9 and fills it in the region underneath the tobacco packet 3. When the slide 31 is operated again by pushing it back in, the loose tobacco 19 is pushed in the dispensing direction and thus compacted (diagram 7c). Tobacco fibres disposed on the boundary between the tobacco housing compartment 9 and the tobacco packet 3 are cut off by the slide 31. In order to facilitate this operation, specially designed edges or blades may be provided on the slide or/and on the housing of the tobacco housing compartment 9. The final density of the tobacco is assumed when the slide 31 is back in its initial position. The tobacco stick is then formed and can be transferred to the cigarette sleeve, which is illustrated in diagram 7d, by known means such as a spoon-shaped slide.
The dimensions of the tobacco packet, in particular its width and length, define the cross-section in which loose tobacco drops into the tobacco housing compartment 9. The height of the tobacco housing compartment 9 defines the third dimension and hence the volume of loose tobacco per cigarette. By preference, the height of the tobacco housing compartment 9 is approximately the same as the diameter of the finished cigarette. The length of the tobacco housing compartment 9, like the length of the tobacco packet 3, is advantageously more or less the same length as the finished tobacco stick of the cigarette. Accordingly, the width of the tobacco packet ultimately defines the quantity of loose tobacco 19 which drops into the tobacco housing compartment 9. The width may be adapted to suit the properties of the loose tobacco 19, in particular the loose density with which it is packaged, so that the finished smoking articles are produced with the matching filling density.
Figure 8 illustrates another embodiment of the invention. In this instance, the tobacco packet 3 is fitted on or pushed onto the filling machine 1. To this end, the tobacco packet 3 has a U-shaped peripheral edge serving as a guide complementary piece 7, which co-operates with a guide 5 on the filling machine 1.
In the simplest variant illustrated here, the guide and guide complementary piece have no other profiling and instead are provided in the form of a web.
However, it will be immediately apparent to the skilled person that the guide may be a T-shaped or dovetail-shaped guide and may also be extended and improved to include many other complementary shapes. A peel-off closure 11 is provided in the region of the U-shaped guide in order to seal the tobacco packet 3 and can be pulled off in order to open the tobacco packet 3.
As for the tobacco used, which is accommodated in a packet proposed by the invention, there is a practical distinction between two groups of application concepts, although the invention is not limited to these. These two groups are packets and systems for loose tobacco on the one hand and packets and systems for tobacco units, which will be referred to as tobacco blocks hereafter, on the other hand.
The loose tobacco to which this application relates should be construed as meaning tobacco with which a packet container has been loosely filled and which has not been compacted due to compression under its own weight, either before or after the packaging process.
A tobacco block, on the other hand, specifically has a homogeneous tobacco density which is higher than the loosely packed density of loose tobacco but is not significantly different from that of the finished cigarette, and in particular the tobacco density of the tobacco block is no higher than twice that of the finished cigarette and no lower than half that of the finished cigarette. The tobacco block used is one with a tobacco density which is close to that of the finished cigarette.
The tobacco block is advantageously of a height and width corresponding to the dimensions of the finished cigarette, i.e. the height of the tobacco block corresponds to the diameter, and the width of the tobacco block corresponds to the length of the tobacco stick of the finished cigarette. Given that the tobacco density of the tobacco block and the finished cigarette are virtually identical, the corresponding dimensions are also therefore virtually identical. However, if the tobacco density of the tobacco block lies above or below that of the finished cigarette, this is compensated by the corresponding adaptations of the height or width of the tobacco block to enable a cigarette of high quality to be produced. The length of the tobacco block corresponds to the number of portions of the multi-portion tobacco quantity in the tobacco block. By preference, the length is selected so that the tobacco portions contained in the tobacco block constitute a whole number. In particular, the number of tobacco portions should be greater than 5.
The tobacco block has a homogeneous tobacco density, which preferably does not assume any predefined structure. In particular, there are no stick-shaped pre-prepared portions. However, it would be conceivable for the tobacco block to predefine perforations in the tobacco at the corresponding parts of the length of the tobacco block, without the tobacco block being sub-divided. Such perforations may be made by various methods. In particular, it would be conceivable to use blades, cutting discs or a water-jet cutting process. The purpose of these perforations is to facilitate the separation of a tobacco portion from the rest of the tobacco block.
By preference, the tobacco block should hold together on the basis of inherent forces. In the case of tobacco cuts with long fibres, this is achieved quite simply on the basis of the length of the fibres. In the case of tobacco cuts with short fibres, this can be achieved by adapting the casing materials. If necessary, the surface of the tobacco block may also be treated accordingly, in particular sprayed.
The invention will be described in more detail below on the basis of different embodiments and with reference to the appended drawings. It may incorporate all the features described herein, both individually and in any practical combination, and may also be defined as a method or a use. Of the drawings:

Examples of embodiments preferably designed for use with loose tobacco.
Figure 1 illustrates an embodiment based on a first example for a system with loose tobacco. Figure 1 a schematically illustrates a filling machine 1; only the part of the guide 5 which constitutes an adapter on the filling machine is of importance as far as the invention is concerned. Illustrated in front of it is a tobacco packet 3.
Shown in the filling machine 1 is the guide 5, which is disposed directly above a tobacco filling opening or the tobacco housing compartment 9. The tobacco packet 3 is provided with a guide complementary piece 7 on its bottom face, which forms an adapter on the tobacco packet. The guide 5 and guide complementary piece 7 are designed so that they fit one another exactly. In this embodiment, both are cut in a converging pattern. When the tobacco packet 3 is pushed into the filling machine 1 in the direction indicated by the arrow, it assumes the desired position above the tobacco filling space (tobacco housing compartment 9) precisely as it reaches the end position, as illustrated in 1 b. Disposed on the bottom face of the tobacco packet 3 is a peel-off closure 11, which seals the contents off from the ambient environment. In order to render the tobacco in the tobacco packet 3 accessible for use in the filling machine 1, the peel-off closure 11 is removed, as illustrated in Figure 1 c.
Figure 2 illustrates an example of an embodiment of the tobacco packet 3 from Figure 1 in detail. Specifically illustrated is an option whereby the guide complementary piece 7 is designed so that the tobacco packet 3 as a whole is of a basic quadratic shape, which is practical in terms of transporting such tobacco packets.
To provide a clearer illustration, the bottom face from Figure 1 is now shown at the top. Provided on a narrow face is a fold-out portion 13, which can be folded out and serves as a gripping portion or gripping tab, enabling a protective strip 15 to be pulled off. As a result, two fold-out tabs 17a and 17b may be seen, which can be folded out and which, together with the thickness of the tobacco packet 3, constitute the guide complementary piece 7 for the guide 5. The peel-off closure 11 may be seen underneath the fold-out tabs 17a and 17b.
Figure 3 provides an even more detailed illustration in three steps a-c of how the fold-out tabs 17 a and b are made ready by pulling off the protective strip 15, which causes the perforations to break open.
Figure 4 shows a longitudinal section through the tobacco packet 3 and illustrates in steps a-d how the peel-off closure 11 is removed from the tobacco packet 3 and the loose tobacco 19 thus released from the tobacco packet 3.
Amongst other things, the tobacco packet 3 based on this embodiment may be made from both a plastic or foil material and cardboard. However, other materials would also be conceivable within the meaning of the invention, e.g. coated cardboard, for example of the type used for drinks packaging.
Figure 5 provides a total of five diagrams (a-e) illustrating another embodiment of the invention for loose tobacco. The tobacco packet 3 is illustrated above a filling machine 1. The tobacco packet 3 has not actually been pushed into the filling machine 1 but has merely been placed above a guide 5. The adapter connection in this embodiment is based on a tilting axis 21. Accordingly, the bottom face of the tobacco packet 3 is provided with a guide complementary piece 7 to permit the tilting action about the tilting axis 21. As illustrated in Figure 5 b, specifically showing a detail on a larger scale, the tobacco packet 3 can be tilted downwards and is preferably retained in a bottom end position due to an automatically snap-fitting closure mechanism 23 (latched closure). A similar closure mechanism is provided on the co-operating face of the tobacco packet 3. In Figure 5c, the tobacco packet 3 has been tilted further downwards and blades sever the seal of the tobacco packet 3 due to the tilting movement. This can be seen even more clearly in Figure 5d, which is a diagram in section rotated by 90 . Figure 5e illustrates how the seal 27 is pulled out and the loose tobacco thus released.
Figure 6 illustrates an exemplary embodiment of the tobacco packet 3 from Figure 5. The tobacco packet 3 is preferably made with a plastic body in which the complementary pieces 29 for the closure mechanism 23 are already provided. The seal 27 may be seen on the bottom face in Figure 6b, which can be cut by the blades 25 along what are indicated as broken lines (Figure 5d) and then pulled off.
Figure 7 shows individual diagrams (a-d) illustrating an example of how the loose tobacco 19 can be subsequently prepared in the case of this embodiment. The same applies to the embodiment illustrated in Figures 1-4.
The tobacco packet 3 connected to the filling machine 1 (diagram 7a) has already been opened and is ready to dispense the loose tobacco 19. When the slide 31 is operated, a tobacco housing compartment 9 is released, so that the state illustrated in diagram 7b is assumed. The loose tobacco 19 drops, essentially conveyed by its own weight, into the tobacco housing compartment 9 and fills it in the region underneath the tobacco packet 3. When the slide 31 is operated again by pushing it back in, the loose tobacco 19 is pushed in the dispensing direction and thus compacted (diagram 7c). Tobacco fibres disposed on the boundary between the tobacco housing compartment 9 and the tobacco packet 3 are cut off by the slide 31. In order to facilitate this operation, specially designed edges or blades may be provided on the slide or/and on the housing of the tobacco housing compartment 9. The final density of the tobacco is assumed when the slide 31 is back in its initial position. The tobacco stick is then formed and can be transferred to the cigarette sleeve, which is illustrated in diagram 7d, by known means such as a spoon-shaped slide.
The dimensions of the tobacco packet, in particular its width and length, define the cross-section in which loose tobacco drops into the tobacco housing compartment 9. The height of the tobacco housing compartment 9 defines the third dimension and hence the volume of loose tobacco per cigarette. By preference, the height of the tobacco housing compartment 9 is approximately the same as the diameter of the finished cigarette. The length of the tobacco housing compartment 9, like the length of the tobacco packet 3, is advantageously more or less the same length as the finished tobacco stick of the cigarette. Accordingly, the width of the tobacco packet ultimately defines the quantity of loose tobacco 19 which drops into the tobacco housing compartment 9. The width may be adapted to suit the properties of the loose tobacco 19, in particular the loose density with which it is packaged, so that the finished smoking articles are produced with the matching filling density.
Figure 8 illustrates another embodiment of the invention. In this instance, the tobacco packet 3 is fitted on or pushed onto the filling machine 1. To this end, the tobacco packet 3 has a U-shaped peripheral edge serving as a guide complementary piece 7, which co-operates with a guide 5 on the filling machine 1.
In the simplest variant illustrated here, the guide and guide complementary piece have no other profiling and instead are provided in the form of a web.
However, it will be immediately apparent to the skilled person that the guide may be a T-shaped or dovetail-shaped guide and may also be extended and improved to include many other complementary shapes. A peel-off closure 11 is provided in the region of the U-shaped guide in order to seal the tobacco packet 3 and can be pulled off in order to open the tobacco packet 3.
The tobacco packet 3 illustrated in Figure 8 is a plastic cap of quadratic shape.
However, it would also be conceivable to use a vacuum pack, such as illustrated in diagrams a-d of Figure 9, for example. In this embodiment, the guide complementary piece 7 has T-shaped profiling. In order to preserve the vacuum in the tobacco packet 3, it is of practical advantage to provide an additional seal 27 above the peel-off closure 11 since it would otherwise not be possible to maintain a vacuum due to the perforations 33.
Figures lOa-c illustrate an improved version of the embodiment from Figure 8.
In particular, the peel-off closure 11 has been replaced by a slide-off closure 35. This closure has a lug 37 which wedges against the edge of the guide 5 when fitted on the cigarette filling machine and (as is clearly visible from the partial section shown in Figure 11) is retained when pushed on so that the tobacco packet 3 opens and releases the loose tobacco 19.
Figure 11 shows four steps a-d involved in using an improved version of the embodiment from Figure 10. In this embodiment, the lug 37 is not mounted right at the foremost edge of the push-off closure 35 but further inwards. The filling device is also provided with a spur 39, which pierces the slide-off closure 35 when the tobacco packet 3 is placed on the guide 5 of the filling machine 1 and slides it off as the tobacco packet is slid further along. The tobacco packet is preferably designed so that there is room to accommodate the closure 35 once slid open.
Examples of preferred embodiments for use with compacted tobacco blocks.
Some of the examples described above in connection with the use of loose tobacco can be directly applied by the skilled person to the use of tobacco blocks.
However, if opting for embodiments of the invention in which the tobacco is dispensed not from the top but from the side, for example, it is no longer possible to rely on its being conveyed by force of gravity. In such cases, it is more practical to use tobacco blocks, although some of the embodiments can be adapted by the skilled person for use with loose tobacco.
Figure 12 shows a partial diagram a illustrating one of various possible embodiments of the invention. A filling machine 1 has a guide 5 suitable for accommodating the tobacco packet 3 by means of the guide complementary piece 7. By means of a gripping tab 41, a tobacco block 43 can be pushed out of the tobacco packet 3. The tobacco block 43 thus arrives in the pressing chamber of a conventional filling machine and is severed from the rest of the tobacco block by the filling machine cover 45 and formed into the tobacco stick. The tobacco stick is again transferred with conventional means such as spoons (not illustrated).
Diagram b of Figure 12b illustrates one possible design of the tobacco packet 3.
Mounted on the narrow face is the guide complementary piece 7, to which a pull-off closure 11 for closing the tobacco packet 3 is attached. Figure 12c illustrates how the gripping tab 41 functions. Having pulled off the closure 11, the consumer takes hold of it (it is illustrated slightly longer than it really as). However, the gripping tab 41 extends into the interior of the tobacco packet 3 in the form of a web-type feeder element and extends round the rear end of the tobacco block 43 in the form of a U-shaped fold in this embodiment. When the consumer pulls on the gripping tab 41, the tobacco block 43 is pulled out of the tobacco packet 3. As may be readily seen from this diagram, the guide complementary piece 7 in this instance is an asymmetrical guide, which means that the tobacco packet 3 can be pushed into the guide 5 in one way only. This approach is preferred because it ensures that the consumer is also able to operate the gripping tab 41 after insertion in the guide 5 of the filling machine 1.
The material of the gripping tab 41 and also the entire web-type feeder element may be made from both plastic and cardboard or a stiffer paper.
However, it would also be conceivable to use a vacuum pack, such as illustrated in diagrams a-d of Figure 9, for example. In this embodiment, the guide complementary piece 7 has T-shaped profiling. In order to preserve the vacuum in the tobacco packet 3, it is of practical advantage to provide an additional seal 27 above the peel-off closure 11 since it would otherwise not be possible to maintain a vacuum due to the perforations 33.
Figures lOa-c illustrate an improved version of the embodiment from Figure 8.
In particular, the peel-off closure 11 has been replaced by a slide-off closure 35. This closure has a lug 37 which wedges against the edge of the guide 5 when fitted on the cigarette filling machine and (as is clearly visible from the partial section shown in Figure 11) is retained when pushed on so that the tobacco packet 3 opens and releases the loose tobacco 19.
Figure 11 shows four steps a-d involved in using an improved version of the embodiment from Figure 10. In this embodiment, the lug 37 is not mounted right at the foremost edge of the push-off closure 35 but further inwards. The filling device is also provided with a spur 39, which pierces the slide-off closure 35 when the tobacco packet 3 is placed on the guide 5 of the filling machine 1 and slides it off as the tobacco packet is slid further along. The tobacco packet is preferably designed so that there is room to accommodate the closure 35 once slid open.

By means of a gripping tab 41, a tobacco block 43 can be pushed out of the tobacco packet 3.

The tobacco stick is again transferred with conventional means such as spoons (not illustrated).
Diagram b of Figure 12b illustrates one possible design of the tobacco packet 3.
Mounted on the narrow face is the guide complementary piece 7, to which a pull-off closure 11 for closing the tobacco packet 3 is attached. Figure 12c illustrates how the gripping tab 41 functions. Having pulled off the closure 11, the consumer takes hold of it (it is illustrated slightly longer than it really as).

This approach is preferred because it ensures that the consumer is also able to operate the gripping tab 41 after insertion in the guide 5 of the filling machine 1.
The material of the gripping tab 41 and also the entire web-type feeder element may be made from both plastic and cardboard or a stiffer paper.
Diagrams a and b of Figure 13 illustrate alternative designs of the guide complementary piece 7. However, the skilled person will be able to conceive of numerous other shapes which may be used in the context of the invention. As may also be seen from Figure 13 a, the gripping tab may be guided through an orifice 47 in one possible embodiment. It would also be conceivable to provide markings 49 on the web element of the gripping tab, displaying the consumption of the tobacco block and the remaining quantity by means of symbols or by legible text.
Figure 14 illustrates an improved version of the tobacco packet 3 from Figures to 13, although a guide complementary piece is omitted from the diagram because any one of the types described above may be used. The essence of the improved feature resides in the fact that the gripping tab has been replaced by a slide which can be operated through an orifice 47 in the tobacco packet. In partial diagram 14 a, the slide is designed so that it extends round the tobacco block 43 at the rear end in a U-shape. When the slide 51 is slid towards the open end of the tobacco packet 3, the tobacco block 43 is also conveyed towards the open end.
However, it would also be conceivable, as illustrated in Figure 14 b, for the slide to be designed so that an elastic slide tab 53 on the rear face of the packet is deflected and supports the tobacco block 43 from the rear end. When the slide is pushed back away from the open end of the tobacco packet 3, the deflection of the slide tab 53 conveys the tobacco block towards the open end.
Markings 49 are provided in the orifice 47 in both part-drawings 14a and 14b, which display the consumption of the tobacco. By preference, the distances between the markings correspond to a multiple based on a whole number representing the tobacco quantity for a cigarette, in particular exactly one cigarette.
In a preferred embodiment, the slide 51 latches in the markings 49 and thus mechanically and perceptibly defines for the consumer the quantity needed for one cigarette.
The described tobacco packets 3 illustrated in Figures 12-14 may also be made from different materials: plastic, cardboard, coated cardboard, etc.
Figure 14 illustrates an improved version of the tobacco packet 3 from Figures to 13, although a guide complementary piece is omitted from the diagram because any one of the types described above may be used. The essence of the improved feature resides in the fact that the gripping tab has been replaced by a slide which can be operated through an orifice 47 in the tobacco packet. In partial diagram 14 a, the slide is designed so that it extends round the tobacco block 43 at the rear end in a U-shape. When the slide 51 is slid towards the open end of the tobacco packet 3, the tobacco block 43 is also conveyed towards the open end.
However, it would also be conceivable, as illustrated in Figure 14 b, for the slide to be designed so that an elastic slide tab 53 on the rear face of the packet is deflected and supports the tobacco block 43 from the rear end. When the slide is pushed back away from the open end of the tobacco packet 3, the deflection of the slide tab 53 conveys the tobacco block towards the open end.
Markings 49 are provided in the orifice 47 in both part-drawings 14a and 14b, which display the consumption of the tobacco. By preference, the distances between the markings correspond to a multiple based on a whole number representing the tobacco quantity for a cigarette, in particular exactly one cigarette.
In a preferred embodiment, the slide 51 latches in the markings 49 and thus mechanically and perceptibly defines for the consumer the quantity needed for one cigarette.
The described tobacco packets 3 illustrated in Figures 12-14 may also be made from different materials: plastic, cardboard, coated cardboard, etc.
Another special design is illustrated in Figures 15a and 15b. In this instance, the tobacco packet 3 is provided with a plastic-foil sleeve. The sleeve is welded at both ends as indicated by reference 55. Aids may be provided at the end to be opened (e.g. notches or tear-off tapes), or, as illustrated, a symbol indicating that the tobacco packet 3 must be cut open. The tobacco packet 3 is provided with guide complementary pieces 7, which are welded on in particular and in this instance provided in a T-shape. The tobacco block 43 can again be conveyed by a gripping tab 41.
Figure 16 shows partial diagrams a-d illustrating another embodiment of the invention. A tobacco packet 3 is inserted in the guide 5 of the filling machine 1 by means of the guide complementary piece 7. In this instance, the tobacco packet essentially constitutes a frame 59 around the tobacco block 43 in the deployment state. In this case, the guide complementary piece is a corrugated web on both sides of the frame. The tobacco block 43 in the frame-type tobacco packet is moved by a feeder wheel 57. A piece is severed from the tobacco block by means of the filling machine cover 45 and transferred into the pressing chamber of a conventional filling machine, in which the tobacco stick is formed and transferred by conventional means, e.g. a spoon, into the cigarette sleeve. The corrugated web of the guide complementary piece 7 is preferably designed so that a mechanical ratcheting can be perceived in co-operation with the feeder wheel 57, which corresponds to the feed movement for the quantity of tobacco needed for a cigarette. In addition to this preferred design of the guide complementary piece 7, the effect of conveying and defining portions may also be achieved on the basis of notches, perforated strips, webs, beads, etc..
Figures 17a and 17b illustrate the tobacco packet 3 proposed by the invention in even more detail. Disposed around the tobacco block is a frame part 59 with the guide complementary piece 7. Disposed on the top face is a foil serving as a pull-off closure 11. Disposed on the bottom face of this embodiment is a fleece 61 which can also be smoked, which completes the tobacco packet 3 and also supports the tobacco block 43 at the bottom. Before the tobacco packet 3 is inserted in the guide 5 of the filling machine 1, the foil of the top pull-off closure 11 is removed. When the filling machine top part is closed, a piece of the tobacco block 43 and a piece of the smokable fleece 61 are transferred into the tobacco pressing chamber. If this is not desirable for reasons of taste, it is also possible to replace the smokable fleece 61 with a foil which can also be pulled off. It is then merely necessary to provide an appropriate support surface on the filling machine, because once the foil has been pulled off, there is no longer anything to provide the supporting effect.
Views a and b of Figure 18 show another design of the tobacco packet 3, which is similar to that illustrated in Figure 15. In this instance, the guide complementary pieces 7 are not illustrated because an explanation will be given of the body of the tobacco packet only. The tobacco packet 3 in this case is designed as a flow pack.
The tobacco packet may be opened by means of a pull-off closure 11. As a result, the consumer can take hold of a gripping tab 41 and pull the tobacco block 43 out of the tobacco packet 3. As with the embodiments described above, guide complementary pieces 7 of various designs may be attached to the packet (adhered, welded, etc.).
Diagrams a and b of Figure 19 illustrate another design of the tobacco packet proposed by the invention. The tobacco packet 3 in this instance is a blister pack.
The parts making up the packet are illustrated: the blister 63 with the guide complementary pieces 7, an air-tight closure foil 65 and a perforated insert paper 67 with gripping tab 41 attached to it disposed in between.
The way the elements of the tobacco packet 3 from Figure 19 operate is more clearly illustrated in Figure 20. A tobacco block 43 is placed in the blister 63. At the bottom face, the blister is sealed by the air-tight closure foil 65. The tobacco block 43 is surrounded by the perforated insert paper 67 and the gripping tab 41 in a U-shaped arrangement. The air-tight closure foil 65 may be opened at one end, thereby making it possible to take hold of the front end of the gripping tab (diagram a). When the gripping tab 41 is pulled, perforations of the perforated insert paper 67 are broken open and the tobacco block 43 is conveyed to the open end (diagrams b and c). The perforations of the perforated insert paper 67 are preferably designed so that with every perforation broken open, a conveyor path is released which corresponds to the quantity of tobacco needed for one cigarette.
Figure 21 illustrates another improved version of the tobacco packet from Figure 19. In this instance, the blister 63 is provided with a perforation 69 which can be broken open to enable the gripping tab 41 to be held. In this case, however, it is of advantage to provide a seal 71 over the perforation in order to preserve the tobacco block 43 in a sealed atmosphere until it is used.
In Figures 12-15, the tobacco packets 3 are fitted on the side of the filling device 1 in a similar manner in each case. One possible, preferred embodiment of the operating and the structure of the filling device 1 will be explained again below. To this end, diagrams a to f of Figure 22 each show a three-dimensional illustration of the filling device and alongside it a section along the longest axis of the tobacco block 43 and transversely to the tobacco stick to be prepared (a-d) and parallel with the filling direction (e-f). The guide complementary piece has been omitted from these drawings.
Figure 22 a illustrates the inserted tobacco packet 3. By pulling on the gripping tab 41, the tobacco block 43 is pushed forwards and a portion is defined by a stop on the housing of the filling device 1, for example (Figure 22b). When the filling machine cover 45 is folded shut, the tobacco quantity forming the defined portion is severed from the tobacco block 43 and formed into a tobacco stick. (Figures 22c+d). Finally, a filter cigarette sleeve 73 is placed in position (Figure 22 e) and the formed tobacco stick is transferred into the filter cigarette sleeve by means of a known slide mechanism (Figure 22f).
Figures 23a-c illustrate a filling device 1 proposed by the invention for use with a blister pack. The opened tobacco packet 3 is inserted by means of the guide complementary pieces 7 in the guide 5 of the filling machine 1 and pushed into the operating position. Precisely with this type of packaging, it is possible and of practical advantage to provide an additional closure lock 75, which positions the tobacco packet 3 in the filling machine. The rest of the procedure takes place in a manner essentially known per se and as described in connection with Figure 22.
All the filling devices described so far have been of the type where the tobacco block is moved towards the transfer system. Within the context of the invention, however, it is also possible that the tobacco block is not moved again once it has been inserted in the filling device and instead, it is the severing and transfer unit which slides respectively by the distance corresponding to a tobacco portion.
This mechanism is schematically illustrated in Figure 24, where the individual steps are illustrated in diagrams a-c. Here again, the guide complementary pieces 7 have been omitted from these drawings.
Finally, within the context of the invention, it is also possible to use a filling device 1 which enables the tobacco portion to be severed and the shaping procedure to be performed in two steps and by separate parts of the device. This is illustrated in Figures 25 a to f in various stages and in a perspective view together with the associated view in section. A cutting wheel 77 severs a tobacco portion from the tobacco block 43 and it is not transferred to the pressing chamber and formed into a stick until the filling machine cover has been opened.

Figure 16 shows partial diagrams a-d illustrating another embodiment of the invention. A tobacco packet 3 is inserted in the guide 5 of the filling machine 1 by means of the guide complementary piece 7. In this instance, the tobacco packet essentially constitutes a frame 59 around the tobacco block 43 in the deployment state. In this case, the guide complementary piece is a corrugated web on both sides of the frame. The tobacco block 43 in the frame-type tobacco packet is moved by a feeder wheel 57. A piece is severed from the tobacco block by means of the filling machine cover 45 and transferred into the pressing chamber of a conventional filling machine, in which the tobacco stick is formed and transferred by conventional means, e.g. a spoon, into the cigarette sleeve. The corrugated web of the guide complementary piece 7 is preferably designed so that a mechanical ratcheting can be perceived in co-operation with the feeder wheel 57, which corresponds to the feed movement for the quantity of tobacco needed for a cigarette. In addition to this preferred design of the guide complementary piece 7, the effect of conveying and defining portions may also be achieved on the basis of notches, perforated strips, webs, beads, etc..
Figures 17a and 17b illustrate the tobacco packet 3 proposed by the invention in even more detail. Disposed around the tobacco block is a frame part 59 with the guide complementary piece 7. Disposed on the top face is a foil serving as a pull-off closure 11. Disposed on the bottom face of this embodiment is a fleece 61 which can also be smoked, which completes the tobacco packet 3 and also supports the tobacco block 43 at the bottom. Before the tobacco packet 3 is inserted in the guide 5 of the filling machine 1, the foil of the top pull-off closure 11 is removed. When the filling machine top part is closed, a piece of the tobacco block 43 and a piece of the smokable fleece 61 are transferred into the tobacco pressing chamber. If this is not desirable for reasons of taste, it is also possible to replace the smokable fleece 61 with a foil which can also be pulled off. It is then merely necessary to provide an appropriate support surface on the filling machine, because once the foil has been pulled off, there is no longer anything to provide the supporting effect.
Views a and b of Figure 18 show another design of the tobacco packet 3, which is similar to that illustrated in Figure 15. In this instance, the guide complementary pieces 7 are not illustrated because an explanation will be given of the body of the tobacco packet only. The tobacco packet 3 in this case is designed as a flow pack.
The tobacco packet may be opened by means of a pull-off closure 11. As a result, the consumer can take hold of a gripping tab 41 and pull the tobacco block 43 out of the tobacco packet 3. As with the embodiments described above, guide complementary pieces 7 of various designs may be attached to the packet (adhered, welded, etc.).
Diagrams a and b of Figure 19 illustrate another design of the tobacco packet proposed by the invention. The tobacco packet 3 in this instance is a blister pack.
The parts making up the packet are illustrated: the blister 63 with the guide complementary pieces 7, an air-tight closure foil 65 and a perforated insert paper 67 with gripping tab 41 attached to it disposed in between.
The way the elements of the tobacco packet 3 from Figure 19 operate is more clearly illustrated in Figure 20. A tobacco block 43 is placed in the blister 63. At the bottom face, the blister is sealed by the air-tight closure foil 65. The tobacco block 43 is surrounded by the perforated insert paper 67 and the gripping tab 41 in a U-shaped arrangement. The air-tight closure foil 65 may be opened at one end, thereby making it possible to take hold of the front end of the gripping tab (diagram a). When the gripping tab 41 is pulled, perforations of the perforated insert paper 67 are broken open and the tobacco block 43 is conveyed to the open end (diagrams b and c). The perforations of the perforated insert paper 67 are preferably designed so that with every perforation broken open, a conveyor path is released which corresponds to the quantity of tobacco needed for one cigarette.
Figure 21 illustrates another improved version of the tobacco packet from Figure 19. In this instance, the blister 63 is provided with a perforation 69 which can be broken open to enable the gripping tab 41 to be held. In this case, however, it is of advantage to provide a seal 71 over the perforation in order to preserve the tobacco block 43 in a sealed atmosphere until it is used.
In Figures 12-15, the tobacco packets 3 are fitted on the side of the filling device 1 in a similar manner in each case. One possible, preferred embodiment of the operating and the structure of the filling device 1 will be explained again below. To this end, diagrams a to f of Figure 22 each show a three-dimensional illustration of the filling device and alongside it a section along the longest axis of the tobacco block 43 and transversely to the tobacco stick to be prepared (a-d) and parallel with the filling direction (e-f). The guide complementary piece has been omitted from these drawings.
Figure 22 a illustrates the inserted tobacco packet 3. By pulling on the gripping tab 41, the tobacco block 43 is pushed forwards and a portion is defined by a stop on the housing of the filling device 1, for example (Figure 22b). When the filling machine cover 45 is folded shut, the tobacco quantity forming the defined portion is severed from the tobacco block 43 and formed into a tobacco stick. (Figures 22c+d). Finally, a filter cigarette sleeve 73 is placed in position (Figure 22 e) and the formed tobacco stick is transferred into the filter cigarette sleeve by means of a known slide mechanism (Figure 22f).
Figures 23a-c illustrate a filling device 1 proposed by the invention for use with a blister pack. The opened tobacco packet 3 is inserted by means of the guide complementary pieces 7 in the guide 5 of the filling machine 1 and pushed into the operating position. Precisely with this type of packaging, it is possible and of practical advantage to provide an additional closure lock 75, which positions the tobacco packet 3 in the filling machine. The rest of the procedure takes place in a manner essentially known per se and as described in connection with Figure 22.
All the filling devices described so far have been of the type where the tobacco block is moved towards the transfer system. Within the context of the invention, however, it is also possible that the tobacco block is not moved again once it has been inserted in the filling device and instead, it is the severing and transfer unit which slides respectively by the distance corresponding to a tobacco portion.
This mechanism is schematically illustrated in Figure 24, where the individual steps are illustrated in diagrams a-c. Here again, the guide complementary pieces 7 have been omitted from these drawings.
Finally, within the context of the invention, it is also possible to use a filling device 1 which enables the tobacco portion to be severed and the shaping procedure to be performed in two steps and by separate parts of the device. This is illustrated in Figures 25 a to f in various stages and in a perspective view together with the associated view in section. A cutting wheel 77 severs a tobacco portion from the tobacco block 43 and it is not transferred to the pressing chamber and formed into a stick until the filling machine cover has been opened.
