Definitions

• the present invention generally relates to a tobacco package and in particular, to a package suitable for storing and delivering tobacco to a cigarette making machine.
• a user may buy loose tobacco suitable for hand rolling and cigarette papers in order to roll cigarettes by hand. It is also possible for the user to purchase loose tobacco and ready made cigarette tubes, and to fill the cigarette tubes with the tobacco, commonly known as make-your-own (MYO) cigarettes.
• MYO make-your-own
• Machines for making cigarettes from loose tobacco have been proposed in the past. Some machines use hoppers arranged to receive loose tobacco and deliver it to the machine for the filling of cigarette tubes while other machines use tobacco capsules for delivering bulk tobacco to the machine.
• a major problem with all of these devices is that it is difficult to accurately divide the tobacco (contained in the hopper or capsule) into individual portions. This results in variations of the delivered tobacco amount from an optimum, i.e. standard, amount required for making a single cigarette. Consequently, cigarettes produced using such devices may vary in size (diameter), firmness (tightness of the filling) and distribution of the filling over the length of one cigarette. In turn, such variations lead to variable performance during smoking, i.e. differences in drawing, taste and time for consumption.
• pre-portioned tobacco packages To address this problem, it has been proposed to use pre-portioned tobacco packages, however all of these solutions have associated drawbacks. For example, some known pre-portioned packages require the user to manually open the packages and transfer a tobacco portion to the cigarette making machine. This can be time consuming for the user and result in loose tobacco being lost in transfer.
• pre-portioned packages include tobacco portions or strands, the outer surface of which is formed by a sheath of material or casing which may be smokeable.
• the content of the casing may be pushed by a plunger axially out of the casing to be transferred to paper tubes via a nozzle.
• Pre-portioned packages using pre-formed tobacco rods can have several disadvantages. Firstly, the machine may need to be configured to open and, in some cases, dispose of the sheath of material, thereby increasing the complexity and cost of the machine. Secondly, amounts of tobacco may be lost in transfer, for example being stuck to the casing or inside the nozzle.
• the present invention seeks to overcome the drawbacks of the prior art.
• a tobacco package for use in a cigarette making machine, the package
• a retainer arranged to receive a plurality of tobacco portions, and being moveable relative to the cover between a first position, in which the tobacco portions are concealed by at least the cover to prevent the machine from accessing the tobacco portions, and a second position, in which at least one of the tobacco portions is accessible.
• the tobacco package may also be referred to as a tobacco capsule or container.
• the tobacco package of the present invention is suitable for storing a plurality of tobacco portions including tobacco rods and delivering the tobacco portions to a cigarette making machine.
• the tobacco package of the present invention provides improved protection to the tobacco portions during transport and allows the tobacco portions to be released by movement of a cover relative to the retainer.
• the cover may slide relative to the retainer.
• Such movement or sliding action may be carried out by a user and is also particularly suited to being actuated by an automatic machine.
• This opening action can be particularly suited to linear actuation by a device for filling cigarette tubes with the tobacco portions.
• the package may therefore be arranged and adapted for use with a MYO cigarette making machine.
• the motion can include a rotation and/or a translation, generally in a plane of the cover.
• the cover may be an outer cover and the retainer or tobacco portion holder may be moveable within the outer cover. This allows the outer cover to provide protection to the entire retainer. Further the retainer may be more efficiently manufactured, since its function is merely to hold the tobacco portions and it need not provide protection to the tobacco portions, which is provided by the outer cover instead. Accordingly, the retainer and the outer cover may be arranged for their respective functions and the overall complexity and/or related cost of the tobacco package may be reduced and manufacturing may be more efficiently achieved.
• the package may be configured such that the tobacco portions can be accessed sequentially by the relative movement of the retainer and the cover, optionally one by one. Sequential revealing of the tobacco portions means that either individual portions or groups of tobacco portions can be revealed by the relative movement of the retainer and the cover.
• the retainer may be provided with a plurality of dividers forming a plurality of chambers or receiving areas, each chamber may be arranged to receive a tobacco portion, or groups of tobacco portions, such that each chamber is located between two neighbouring dividers. This may facilitate the division of loose tobacco into portions, enabling the delivery of precise amounts of tobacco to a cigarette making machine. Furthermore, using chambers to hold individual portions of tobacco is a cheaper and more efficient way of proportioning the tobacco than known solutions. In addition, opening a chamber by moving the retainer relative the cover ensures a quicker and cleaner procedure of delivering precise amounts of tobacco to a cigarette making machine.
• At least one of the chambers may be arranged to have a substantially part-cylindrical wall. This allows the chamber to support a cylindrical tobacco rod and to guide it and protect it from damage.
• the tobacco portion may have a tobacco portion sleeve, which can be cylindrical.
• a wall of the chamber may comprise at least one gripping portion for releasably retaining the tobacco portion sleeve in the chamber receiving the tobacco portion.
• Using a tobacco portion sleeve provides structural support and protection to the tobacco portion, enabling the tobacco portion to be gripped and displaced in the chamber without deforming the tobacco portion.
• the sleeve may be provided with an adaptor arranged to be engaged by the cigarette making machine.
• the chamber holding the tobacco portion may be provided with an opening arranged to allow engagement by the machine with the adaptor to pull out the tobacco portion of a side of the chamber.
• the opening may be in a longitudinal direction of the tobacco sleeve or chamber and the tobacco portion may be extracted or driven out by the adaptor in a direction substantially perpendicular to the direction of movement of the retainer.
• the tobacco portion may be pulled or pushed out in a direction parallel to the longitudinal axis of the chamber.
• this facilitates ejection of the tobacco portion from the retainer by sliding the tobacco portion using the adaptor and without deforming the tobacco portion.
• the package may comprise engaging means for engaging with a cigarette making machine.
• the engaging means may optionally comprise a step or a ridge or a recess on the package. This can allow a corresponding member of a cigarette making machine to engage with the step or ridge on the package, to retain the package on the machine. This can allow for the prevention or removal of the package, in particular during use of the package by the machine, so that operator intervention does not cause any damage to the machine or tobacco portions during extraction of the tobacco portions from the retainer.
• the retainer may comprise a machine engagement portion, arranged to be engagable by a machine for filling cigarettes to displace the retainer relative to the cover.
• Providing engagement means on both the cover and the retainer allows the machine to actuate the package to displace the cover relatively to the retainer. In this way, the machine may release and extract tobacco portions from the package in a controlled and optionally automated manner.
• the engagement portion may be arranged such that the machine can pull a tobacco portion, or the retainer, relative to the cover. This can allow the cover to remain static relative to the machine, while the tobacco portion and/or the retainer can be drawn into or toward the machine to allow a tobacco portion in the retainer to be used by the machine. Additionally or alternatively, the machine engagement portion may be used to fine-position the package inside the machine and control the relative movement of the retainer to the cover.
• the package may comprise locking means for locking the package in a closed position. This can ensure that the package does not unintentionally release tobacco portions or expose them to damage during transport and/or prior to use. Further, the locking means may be arranged such that they cannot be opened without specific tools or specific parts of a machine to actuate the locking means. This provides for the access to the package to be limited to either authorised individuals with specific tools and/or limited to a machine which will use the tobacco portions. This can prevent the wrong kind of tobacco portions being placed in the package by an unauthorised individual and can ensure that the tobacco portions are not inadvertently damaged by exposure by an unauthorised user.
• the locking means may further be arranged to be actuated by a release mechanism of a cigarette making machine to open the package.
• the package may comprise at least one part which is formed of a substantially rigid material.
• a substantially rigid material may be a thermoplastic or other plastics material, metal, carbon-fibre or other, generally rigid, synthetic or organic materials or metals.
• This part may provide the structural rigidity required in particular in the area in which the package is arranged to engage with a machine.
• the engagement portion of the package and/or the retainer itself and/or the locking means may be formed from a substantially rigid material.
• Remaining parts of the package may be formed from a less rigid sheet of material, such as cardboard, sheet plastic, films or other more flexible material. This material may be folded from a blank to form the structural part of the package.
• a tobacco portion held in the retainer may be suitable for making a single cigarette. This enables a user or cigarette making machine to make individual cigarettes using the exact required amount of tobacco.
• the tobacco portions are tobacco rods.
• a tobacco rod may comprise tobacco wrapped in foil such as a non smokeable but tear resistant foil or paper thereby providing structural rigidity to the tobacco portion.
• using tobacco portions formed as tobacco rods instead of loose tobacco facilitates the tobacco portions to be accessed by a user or cigarette making machine, particularly when a machine engagement portion is used.
• Tobacco rods also enable a chamber of the retainer to hold the tobacco portions in place when a gripping portion is provided which can releasable hold the rigid rod.
• a further advantage is that the tobacco rods may be used to fill standard cigarette tubes having matching dimensions.
• the cover may be profiled, for example by comprising additional walls to provide the tobacco package with a profiled shape for allowing insertion of the package in the cigarette making machine only in a correct orientation.
• this prevents wrong insertion of the package into the slot of the cigarette making machine, e.g. insertion into wrong slot or wrongly oriented insertion.

• FIGS 1A to 1 C show components of a tobacco package 1 according to the present invention.
• the tobacco package 1 comprises a retainer 2 and a cover 3 which surrounds the retainer 2.
• the retainer 2 comprises a plurality of chambers 4, wherein each chamber 4 may hold a tobacco portion or tobacco rod (not shown).
• the tobacco portions therefore may have a generally cylindrical form, and may comprise a wrapper such as a tear resistant foil or paper in which the tobacco is wrapped.
• the wrapper may or may not be smokeable.
• the cover 3 is a rectangular cuboid formed of two sets of opposing sides or vertical walls (3 ⁇ ;3 ⁇ '), (3B; 3 ⁇ '), with two opposing sides missing. Therefore the cover 3 has two open ends (in this example, an open top side and an open bottom side), thereby forming a sleeve. It will be appreciated that the cover 3 may have other suitable shapes (e.g. cylindrical or other types of parallelepipeds) which allow a retainer 2 to be received in and moved through the cover 3.
• the retainer 2 and the cover 3 may be made of any suitable material such as cardboard or deep drawn plastics or may be moulded from another deformable material.
• the cover may be made from a substantially air tight and/or moisture tight material to substantially preserve a level of relative humidity in the package when the package is in a closed configuration.
• the cover may be folded from a sheet of a relatively thin card, plastic or paper and cut through a blank and bonded to form the desired shape.
• the cover 3 receives the retainer 2 by sliding the retainer 2 inside the cover 3. It is desirable, therefore, that the dimensions of the retainer 2 generally match the dimensions of the cover's interior, in order to maximise the size of the retainer 2 which may be received inside the cover 3.
• the length L of the cover 3 may be between 5 and 1 1 cm, and the width w of the cover may be between 0.5 and 2 cm for example, so as to enable the retainer 2 to have a length matching that of a standard cigarette.
• the heights of the cover 3 and retainer 2 may depend for example on the number of tobacco portions held in the retainer. Typically, the heights of the over 3 and retainer 2 are between 5 and 15 cm, to house between five to twenty tobacco portions.
• Figure 1A is a schematic view inside an exemplary tobacco package 1 in accordance with the present invention.
• the retainer 2 may comprise a plurality of parallel dividers 5, shaped as shelves in this example.
• each divider is provided between two side members 2A; 2A' of the retainer 2.
• the side members in this example are parallel side walls.
• a side member 2A may have any suitable shape such as a column, for example.
• the side members 2A; 2A' are spaced from each other by a distance shorter than the length L of the cover 3 and the shelves 5 have a width which is shorter than the width w of the cover 3.
• the shelves 5 are used to divide the retainer 2 into chambers 4, wherein each chamber 4 is enclosed by two neighbouring shelves 5 and two opposing cover walls 3B; 3B'. Accordingly, in this example, the chambers 4 are separate and the retaining component 2 contains separate tobacco portions provided between the shelves 5.
• the shelves 5 are perpendicular to the cover walls 3A; 3B and the shelves 5 are equally spaced from each other in order to form equally sized chambers 4. Providing equally sized chambers 4 enables portioning of the tobacco into equal amounts (each amount being suitable for making a single cigarette, for example) when the chambers 4 are filled with tobacco.
• Figure 1 B illustrates the tobacco container 1 in a closed position wherein the retainer 2 is fully surrounded by the cover 3. In this position, each chamber 4 of the retainer 4 is closed on all sides.
• the height of the side members 2A; 2A' of the retainer 2 is greater than the highest walls of the cover 3 (i.e. greater than h2). Accordingly, two opposing walls 3A of the cover 3 (of height h1 ⁇ h2) are shorter than the side members 2A;2A' in order to expose, in the closed position, parts of the side members 2A; 2A' (indicated by the ellipse).
• a sealing member or locking mechanism may be used to seal or lock the container in the closed position.
• the side members 2A;2A' may have a plurality of grooves 6 which may have the shape of a V, referred to as V-grooves, suitable for engaging with the cigarette making machine.
• V-grooves may be used to fine position the retainer 2 within a slot in the machine, by engaging with pins provided inside the machine's slot.
• a user may insert the package 1 into a suitable slot of a cigarette making machine (not shown) and manually push down the retainer 2 such that the retainer 2 moves relative to the cover 3 to an initial position illustrated in Figure 1 C.
• a first chamber 4 (the chamber 4 located at the bottom of the retainer) is open on two opposing sides, exposing a tobacco rod or tobacco portion inside the chamber 4. Opening two opposing sides of the chamber 4 allows for the tobacco rod or portion inside the chamber 4 to be pushed from one side of the chamber and released through the other side by a quick and easy motion, for example by a compressor of the machine (not shown).
• the cover 3 and slot have matching shapes, to enable insertion of the package 1 into the slot.
• the cover 3 may be profiled such that is may only be inserted into the slot in a particular (i.e. correct) orientation. In other words, wrong insertion of the package 1 into the slot of the cigarette making machine (e.g. insertion into wrong slot or wrongly oriented insertion) is not possible.
• the retainer 2 may move further relative to the cover 3, to a second position wherein a second chamber 4 (located above the first opened chamber) becomes open. Thus, a second tobacco portion may be delivered to the machine. This relative movement may be continued until all chambers 4 have been opened and the tobacco has been delivered to the machine.
• Figure 2 is a perspective view of a tobacco package 1 in accordance with the present invention inserted into a cigarette making machine 7.
• the machine 7 is provided with pins 8 suitable for engaging with the retainer 2 in order to aid the positioning of the package 1 inside the machine.
• Two pins 8 are provided either side of the package 1 and fit into the grooves 6.
• the machine has a compressor 9 which pushes the tobacco portions out of the opened chamber 4, through the opened sides of the chamber 4.
• the compressor 9 comprises a member that is arranged such that is can pass through the chamber 4 in a direction substantially perpendicular to the longitudinal axis of the chamber 4 to engage and move the tobacco portion out of the chamber 4.
• Figure 3 is a detailed view of a package 1 , showing a side member 2A of a retainer 2 comprising a plurality of V-grooves 6 engaging with pins 8.
• the side members 2A of the retainer 2A may be provided with joints 10 suitable for receiving a divider 5, as shown in Figure 4A.
• the joints 10 are preferably made of elastic material such as rubber in order to allow a slight movement ('flapping') of the dividers 5 relative to the side members 2A. This movement enables adaptation of the shelves 5 to engage with the compressor 9, thereby enabling relative movement of the retainer 2 relative to the compressor 9 to fine position the retainer 2 with respect to the compressor 9.
• the dividers may be shelves 5 which have variable thickness along their width as shown in Figure 4B. In other words, the shelves 5 have a profile. The profiling of the shelves 5 enables further adaptation of the shelves 5 for engaging the tobacco compressor 9 which, in turn, allows the compressor to move the retainer 2 relative to the cover 3.
• Figure 5A is a perspective view of a retainer 2A wherein the side members 2A of the retainer 2 are elongated members or columns 2A rather than walls.

• the machine 80 may comprise a moveable member which can be moved into position to lock the tobacco package 10 in place during operation of the machine 80.
• the machine 80 may be equipped with a retainer engagement portion 82 which is arranged to engage the retainer 20 and to move the retainer 20 relative to the cover 30 of package 10. As such, a machine 80 may cause relative movement of the cover 30 relative to the retainer 20 to expose tobacco portions for filling cigarette tubes.
• the tobacco package 10 is opened by linear movement of the cover 30 relative to the retainer 20.
• a retainer and cover arrangement which is opened by non linear movement, such as rotation of one of the cover and the retainer relative to the other or by a combination of rotation and translation of the cover relative to the remainder of the package.
• a first part of cover 30 may be integral with retainer 20 to provide a first part of the covering function to enclose tobacco portions within the package 10 and a second portion of cover 30 may be rotatable relative to the first part of the cover to expose tobacco portions for use in a machine 80.
• Figures 9A to 9C illustrate how the tobacco package 10 and machine 80 may be configured to allow a machine to unlock and open a tobacco package 10 of the present invention.
• Figure 9A shows a package 10, which is in a closed configuration and which is engaged with a machine 80.
• Figure 9B illustrates the detailed section A of Figure 9A. The figure illustrates details of how a locking mechanism 70 of the present invention may be engaged by a locking means engaging device 82 of a machine 80.
• Recess engagement means 72 of the locking mechanism 70 comprises a displacement portion 721 for engagement with a displacing member to displace the recess engagement means, or pin, 72.
• This displacement portion is located within the package 10 and behind a wall 74 of the package 1 , so that no direct linear access to the displacement portion 721 is available to a user to actuate the recess engaging member 72.
• the wall 74, and opening 75 in the wall are configured such that a locking mechanism release member 83 must be introduced into opening 75 substantially in a first direction and then displaced in a second direction, substantially perpendicular to the first direction in order to release the locking mechanism.
• release member 83 of machine 80 must be introduced into opening 75 in a first direction, substantially in the direction of arrow 84 in the figure, and subsequently displaced in a direction substantially perpendicular to the first direction in a direction of arrow 85 in the figure, to displace the recess engagement means 72 via the displacement portion 721 to unlock the package 10 for opening.
• Machine 80 may further comprise package engaging means 86.
• Package engaging means 86 may be a pin and may be manually actuated or may be actuated by the machine. The actuation may be in a substantially linear manner, as indicated by arrow 861 , optionally by a rotary or linear motor or a solenoid, or any other substantially linear drive. Alternatively, package engagement means 86 may be rotated to engage the package 1 at machine engaging portion 101. This can be achieved by means such as a screw thread or by rotating the member 86 about a pivot.
• the machine 80 may be configured such that the tobacco extraction and cigarette tube filling process is only initiated if the package engagement means 86 is in the package engaging position. This can prevent the user from removing the package during operation of the machine, which could otherwise damage the machine and/or the package.
• the machine may therefore comprise a controller, which may be coupled to either or both of: drive means for the package engagement means 86; and drive means for locking means engagement device 82, or cover engagement means for displacing the cover.
• the controller may be configured to only allow actuation of the displacement means and any further mechanisms for carrying out the tube filling process when the package is engaged by the machine, preferably via package engagement means 86.
• Figure 9C shows the arrangement of Figure 9B, in which the locking mechanism 70 has been actuated to an unlocked position by movement of release member 83 of machine 80 in a direction of arrow 85.
• release member 83 has a displacement member engagement portion 86 which is configured to both displace the locking means to unlock the package 10 and further, by engagement with element 74 of the package, the member 86 can further engage the retainer 20 of the package 10 to cause relative displacement between those two components to open the package 10.
• a machine having a release member configured to actuate a locking mechanism 70 of the package 10.
• the machine also comprises an actuation element arranged to engage the package to cause relative movement between a cover 30 and a retainer 20 of the package 10.
• the release member and the actuation element can be the same element in the illustrated example.
