Definitions

• This invention relates to packaging for tobacco.
• the invention relates to a packet and blanks for making the packet.
• cut tobacco that is used by consumers in roll-your-own (RYO) products is packaged in tobacco pouches.
• the consumer removes a portion of tobacco from the pouch before constructing a smoking article, such as a cigarette with use of a separate cigarette paper.
• Tobacco pouches are conventionally formed from a sheet of plastic material that is folded over along one edge to form a closed edge and an overlapping portion. The overlapping portion is sealed about two side edges to form a pocket in which the cut tobacco is contained.
• Pouches typically have a flap that extends from a rear wall of the pouch and folds over the open end to prevent spillage of the contents.
• Use of the pouch over prolonged periods may result in deterioration of the freshness and flavour of the cut tobacco.
• the deterioration in quality of the cut tobacco may be due to the loss of moisture or aroma from the cut tobacco. Simply folding a flap over the opening of the pouch may not be sufficient to eliminate the deterioration of the cut tobacco contained therein.
• a first aspect of the present invention provides a packet for tobacco comprising a container and a lid attached to the container, the container comprising front and rear panels, two side opposing panels and an end panel, wherein an opening is provided opposite the end panel, the lid being hingedly attached to the rear panel and being operable to extend across the opening and at least part of the front panel, the lid comprising two or more consecutive lid panels, wherein a first of the two or more consecutive lid panels provides the hinged attachment to the rear panel and the last of the two or more consecutive lid panels has engaging means which is operable to engage with the container.

• RYO roll-your-own
• a make-your-own smoking article such as a cigarette
• the packet is suitable for use in vending stations, such as those conventionally used in the sale of other tobacco-related products such as cigarettes.
• Vending stations include vending machines, vending display cabinets and the like from which smoking articles are displayed and sold.
• the container may provide complementary engaging means which is operable to engage with the engaging means.
• the engaging means and the complementary engaging means may be provided by hook and loop type fastener (Velcro®).
• the engaging means and/or the complementary engaging means may be provided by adhesive applied to the lid and/or the container. Suitable adhesive may be semi-permanent type, for example gummed paper or glued paper having a removable backing to reveal the adhesive surface.
• the complementary engaging means may be provided by an attachment to the container or by a surface or an edge of the container.
• the complementary engaging means is provided on the region of the container that the engaging means makes contact with on closing the lid.
• the engaging means may be a tab and the complementary engaging means may be a slot into which the tab is insertable.
• a tab may extend from one or more edges of the lid. Accordingly, one or more slots may be provided on corresponding edges or panels which form the container; the corresponding edges or panels are provided .by the part(s) of the container that the engaging means comes into contact with on closing the lid.

• the recessed portion may be formed by a (re)movable section, which may be hinged along one edge to the container. Provision of a hinged attachment to the container helps to eliminate a potential problem of disposing of the removable section. Removal or opening of the removable section by a person other than the consumer may be indicative of tampering.
• the contents " of the container may be a sealable pouch containing tobacco. Therefore, removal or opening of the removable section allows access to the seal on the pouch. Accordingly, removal or opening of the removable section by a person other than the consumer may be indicative of tampering with the seal and/or contents of the pouch.
• the first of the consecutive panels forming the lid does not have any flaps or panels attached to its edges that correspond with the sides of the packet. Therefore, when closing the lid there may be a slight void between the side edge of the lid and the side panel of the container.
• the side panels of the container may each comprise a flap extending from an edge that corresponds with the opening of the container.
• the flaps are foldable in towards the container such that on closing, the lid abuts the flaps; thereby eliminating the void.
• the flaps are also operable to strengthen the side panels of the packet by reducing the incidence of deformation of the side panels that may be caused by the lid portion coming into contact with the top edge of the side panel that coincides with the opening of the container.
• the flaps may also be operable to reduce the ingress of dirt and dust into the container.
• the blank may be folded by manual folding or by an automated folding process or a combination of both to-form a packet in accordance with a first aspect of the present invention.
• the method of folding the blank to form the packet may involve first placing a poueh containing tobacco onto the blank and then folding the blank around the pouch.
• the packet may be partially erected such that the pouch is insertable into the container portion prior to completing erection of the packet.
• Partial erection of the blank may involve folding at least some of the panels forming the blank to make up a tube having two openings or folding at least some of the panels forming the blank to make up a container with an opening at one end. Erection of the packet may be completed after the contents are inserted and by folding any remaining panels of the container and the panels forming the lid around the pouch.

• the tube 30 has two open ends Al, A2; the open end A2 of the tube 30 is where the lid 4 is attached and the open end Al is where the base/end 16 of the packet 100 is formed;
• the closure tab 24 is intended to be used by the consumer to use a pack that can be reopened and reclosed by the interaction of the closure tab 24 with the slot 26.
• the closure tab 24 may remain embedded in the reinforcing panel 22' until the consumer prises the closure tab 24 from the reinforcing panel 22'.
• the closure tab 24 is foldable through 90 degrees about the fold line LF3 and is insertable in the slot 26, thereby enclosing the filled pouch P and locking the packet 100.
• the packet 100 may be reopened and reclosed easily by the consumer.
• the blank B2 may be supplied for insertion of the pouch P in a partially erected form, wherein the blank B2 is made up to step (e) above.
• the parts of the tube 30 may be flattened for shipment by for example folding about fold line CF21 or CF23 through 90° to provide a substantially flat piece which is suitable for stacking.
• To insert the pouch P the tube 30 is reformed by reverse folding about the same fold line. Thereafter, the remaining stages (f) to (1) of the assembly process.detailed above are completed to form the packet 100.
• the erected packet 100 including its contents (tobacco pouch P) may be wrapped in a suitable outer wrapper, for example cellophane, which is removable by the consumer.
• a suitable outer wrapper for example cellophane
• the blanks Bl and B2 are illustrated in Figures 5 and 6a with a U-shaped recess in the front panel.
• the packet comprises a removable section 18a.
• Such packets can be formed from blanks having the same layout as those illustrated in Figures 5 and 6a except that the blanks include a (re)movable section 18a occupying the void corresponding to the U-shaped recess.
• the section 18a may be hinged along one of its edges to the container to allow access into the container without having to fully detach the section 18a from the container.
• the recess is illustrated as being generally U-shaped.
• the recess left when the section 18a is opened is illustrated as a combination of two substantially U-shapes; a larger U-shape depends from the open end A2 and a smaller U-shape depends from the bottom of the larger U-shape towards the closed end of the packet.
• the recess provided on the front panel is shaped to facilitate access to the pouch and the contents within it.
• FIG. 7a and 7b there is illustrated an example of a packet 100 for containing a tobacco pouch P, wherein the leading edge El of the lid and the free edges El 1, E12 of the last panel that forms the lid have closure panels CPl, CP2 and CP3 depending from them.
• the closure panels CPl, CP2, CP3 overlap corresponding panels of the container to close the packet 100.
• the lid 4 comprises two panels; a lid end panel
• closure panels CPl, CP2 and CP3 depend from the edges El, El 1 and E12 respectively of the lid front panel 22. Adjacent edges of the closure panels CPl and CP2 and the adjacent edges of closure panels CP2 and CP3 are joined together by means of tabs Tl and-T2 respectively (see figures 8a and 8b), which fix to the inside face of closure panel CP2 to form a rim comprising closure panels CPl, CP2, CP3 that overlap with corresponding panels 12, 16 and 10 of the container when closed.
• the rim may close against the container with an interference fit such that the packet 100 remains closed until the lid is actively moved to open the packet 100.
• the lid comprises an end panel (not visible in Figure 7b) that overlaps the opening A2, a lid front panel 22 that overlaps the full depth of the container front panel, an additional end panel 30 that overlaps with the container end panel and a lid rear panel 32 which overlaps the whole of the depth of the container rear panel 14 when the packet 100 is closed. Therefore, to close the packet 100 the lid wraps around the pack and closure is effected when the lid rear panel 32 comes into contact with the container rear panel 14 such that the rim comprising closure panels CPl, CP2, CP3 overlaps with corresponding panels 12, 16 and 10 of the container. The rim may close against the container with an interference fit such that the packet 100 remains closed until the lid is actively moved to open the packet 100. Closure by the rim is effected in the same way as in the packet 100 illustrated in Figure 7a.
• the container portion of the pack is formed in the same way as described above in respect of figures 5 and 6a.
• the closure panels CPl, CP2 and CP3 which form the rim when folded are included in the Figures 8a and 8b instead of Hie closure tab 24 ( Figures 5 and 6a).
• the rim comprising closure panels CPl, CP2 and CP3 is formed by firstly folding the tabs Tl and T2 about fold lines RF4 and RF2 respectively such that they upstand from the closure panels CPl, CP3; secondly closure panels CPl and CP3 are folded about fold lines RFl and RF5 such that they upstand from the lid front panel 22; thirdly, the closure panel CP2 is folded about fold line RF3 such that it upstands from the lid front panel 22; and finally the tabs Tl and T2 are stuck to the inner face of the closure panel CP2.
• the embodiments described and illustrated refer to packets, wherein the edges are formed by the panels at right angles, thereby producing substantially sharp edges.
• this is not to be considered limiting, because the blanks for making the packet and the edges of the packet can be formed such that resultant edges are rounded or bevelled or elliptical or any other shape including those known in the art.
