Definitions

• the present invention relates to a pack for tobacco, particularly for loose tobacco.
• Tobacco can be supplied to the consumer as loose tobacco, either for making hand-rolled cigarettes, or as pipe tobacco.
• loose tobacco of this type is packaged in pouches, comprising a bag portion for containing the tobacco and a flap portion extending from the top of the bag which can be folded over the opening of the bag and sometimes wrapped around the bag before being stuck down to close the pouch.
• the pouch is typically made from paper or thin cardboard laminated or otherwise covered with a layer of transparent plastics material through which printed labelling on the paper or card can be seen, or from plastics material alone upon which printing can be executed.
• the present invention seeks to address some of these issues.
• a first aspect of the present invention is directed to a pack for tobacco, comprising: a receptacle for receiving tobacco, the receptacle having an upper face that closes the receptacle; and a hinge line running across the upper face, the hinge line dividing the upper face into a lid portion and a fixed portion, the fixed portion remaining in a closed position and the Hd portion rotatable about the hinge line between a closed position that is substantially coplanar with the fixed portion, and an open position that gives access to the interior of the receptacle.
• the fixed portion makes available a flat surface for receiving tobacco that is removed from the pack when the lid portion is opened, and also for accommodating cigarette papers and other smokers' materials while the smoker is opening and closing the pack and handling the tobacco. Then, the area of the flat surface can be increased by closing the lid portion, giving a convenient flat surface for rolling a cigarette.
• the receptacle may have a parallelepiped shape, defined by the upper face, a lower face opposite the upper face, and four side walls extending between the upper face and the lower face, the upper and lower faces having a substantially larger area than the side walls.
• a parallelepiped shape is convenient for efficient packing of the boxes into cartons for shipping and storing, and for fitting the packs into vending machines and displaying the packs for retail purposes.
• the hinge line may run between two opposite corners of the upper face. This gives strength to the pack to resist crushing and other damage, and also to give a more rigid flat surface for the smoker.
• the pack may comprise one or more abutment members extending from the receptacle adjacent the underside of the upper face, and positioned to inhibit the Hd portion from rotating below the plane of the fixed portion. Again, this helps to maintain the rigidity of the upper face to give the smoker an improved flat surface. Also, movement of the Hd portion into positions inside the receptacle from which it would be more difficult to open the pack is limited or prevented.
• the pack may further comprise a closure assembly operable to releasably maintain the lid in its closed position.
• the closure assembly may comprise one or more protruding or recessed portions on an edge of the lid portion, and one or more corresponding recessed or protruding portions on an adjacent edge of the receptacle, the portions on the edge of the lid portion interengaging with the portions on the adjacent edge in an interference fit when the lid portion is in the closed position.
• a closure assembly of this type can be easily opened with one hand.
• the closure assembly can be arranged to give a largely smooth and continuous upper face without irregularities on which pieces of tobacco may become caught, and at the same time provide closure of the pack with a minimum of material.
• the closure assembly may be configured such that when the Hd is in the closed position there are substantially no discontinuities in the plane of the upper surface.
• the pack may be formed from a folded blank.
• Figures IA and IB show perspective views of a pack according to first embodiment of the invention, respectively in open and closed positions;
• Figures 2A, 2B and 2C show perspective views of packs according to further embodiments, having various outer shapes;
• Figures 3 A, 3B and 3C show partial cross-sectional views of packs according to further embodiments, having various abutment members that limit movement of a lid portion; and
• Figures 4A and 4B show perspective views of a pack according to a yet further embodiment, respectively in open and closed positions and having a closure assembly.
• Figure IA shows a perspective view of a pack according to an embodiment of the invention, the pack being in an open configuration.
• Figure IB shows the same pack in a closed configuration.
• the pack 10 is in the form of a receptacle for tobacco, which in this embodiment has a parallelepiped shape.
• the receptacle is defined by an upper face 12, a lower face opposite the upper face 12 (not visible in the Figures), and four side walls 14 that extend between and join the lower face and the upper face 12.
• the upper face 12 and the lower face each have a square shape.
• the edges of the upper face 12 and the lower face are significantly longer than the vertical edges of the side walls 14, so that the upper face 12 and the lower face have a much greater surface area than the side walls 14.
• the receptacle has the form of a shallow tray with a lid, where the upper face 12 forms the "lid” and acts to close the receptacle and retain its contents, in this case loose tobacco 16.
• the upper face 12 is divided in two by a hinge line 18 that runs across the upper face 12 from one corner to the diagonally opposite corner.
• the hinge line 18 is best seen in Figure IB.
• the hinge line 18 defines two portions: on one side of the hinge line 18 the upper face 12 ha.s the form of a lid portion 20, and on the other side of the hinge line 18 the upper face 12 has the form of a fixed portion 22.
• the hinge line 18 may be formed for example by a score line, a line of perforations, or a line of thinner material.
• the fixed portion 22 is joined at its edges other than the edge defined by the hinge line 18 to the side walls 14.
• the fixed portion 22 thus has a fixed, closed position relative to the receptacle, and is not movable relative thereto.
• Tobacco 16 is accommodated in the space below the fixed portion 22, however.
• the lid portion 20 is not joined to the side walls, and is instead connected to the receptacle by way of the hinge line 18, so that it is continuous with the fixed portion 22.
• the Hd portion 20 is rotatable about the hinge line 18 between a closed position shown in Figure IB and an open position shown in Figure IA. When in the closed position, the Hd portion 20 is in contact with or closely adjacent to the top edges of the side walls 14 so as to close the receptacle.
• the Hd portion 20 and the fixed portion 22 are substantially co-planar, so that the upper face 12 has the form of a substantially flat surface.
• the user lifts an edge of the lid portion 20 and rotates the Hd portion 20 about the hinge line 18 so as to fold it towards the fixed portion 22. This opens an aperture under the lid portion 20 which is delineated by the hinge line 18 and the upper edges of the side walls 14.
• This arrangement gives a pack that is particularly well-adapted to the needs of a smoker who wishes to roll his own cigarettes.
• the pack is easily opened (in some embodiments with one hand, as described later) to give access to the tobacco within.
• the fixed portion 22 of the upper face 12 offers a flat surface on which the smoker can deposit tobacco 16 removed from the pack 10.
• This surface can also accommodate cigarette papers, matches, filters and the like while the smoker takes tobacco 16 from the pack 10.
• the flat surface can then be used as a surface on which to roll a cigarette using the tobacco from the pack, and more usefully, a larger area can be obtained by lowering the Hd portion 20 back to its closed position, so that the whole of the upper surface forms a single flat plane on which the cigarette can be made.
• pack shown in Figures IA and IB is useful in that square packs can be more easily deposited into larger cartons for shipping, since it is immaterial which way round the pack is put into the carton. Also, the diagonal arrangement of the hinge line imparts rigidity to the pack, since the pack is then braced across its longest dimension. Improved rigidity reduces damage and crushing during shipping, storage and use of the pack.
• packs according to the invention are not limited to the configuration of Figures IA and IB, and can take a wide range of shapes.
• Figure 2A shows a pack 30 which has the form of a square parallelepiped, like the pack 10 of Figures IA and IB, but in which the hinge line 18 is positioned parallel to two opposite sides of the upper face 12.
• the two options of a diagonal hinge line or a parallel hinge line may similarly be implemented with a parallelepiped pack in which the upper and lower faces are rectangular.
• Figure 2B shows a pack 40 in which the upper face 12 and the lower face are triangular, so that these faces are connected by three side walls 14.
• the hinge line 18 runs across the upper face 12 from one corner of the triangle to the centre of the opposite side.
• Other polygonal shapes can also be used, both regular and irregular.
• Figure 2C shows a pack 50 in which the upper face 12 and the lower face are circular, connected by a single cylindrical side wall 14.
• the hinge line 18 is defined along a diameter of the upper face 12.
• the upper and lower faces may alternatively be oval.
• Square, rounded or bevelled edges or corners may be used in conjunction with any shape of pack.
• the hinge line 18 bisects the upper face 12, so that the Hd portion 20 and fixed portion 22 have the same area. This maximises both the size of the aperture through which the user accesses the contents of the pack 10 and the available flat surface offered by the fixed portion 22 while the lid portion 20 is open.
• the hinge line may be positioned to divide the upper face into two unequal parts if desired.
• the pack 10 further comprises a rim or abutment member 24. This is a portion that extends inwardly, towards the interior of the receptacle, from the upper edges of the side walls 14, at least on those side walls 14 adjacent to the edges of the lid portion 20.
• the rim 24 thus extends partly underneath the lid portion 20 so as to be adjacent to the underside edge of the lid portion 20 when the lid portion 20 is in its closed position.
• This arrangement stops the lid portion 20 from rotating too far about the hinge line 18, past its closed position, and falling down into the interior of the receptacle, from where it would be difficult to be opened.
• the abutment with the rim 24 keeps the lid portion 20 and the fixed portion 22 substantially coplanar if pressure is exerted on the upper face 22, thus maintaining the upper surface 12 flat while a cigarette is rolled upon it.
• FIG 3A shows a first example embodiment of the rim 24, illustrated as a partial vertical cross-sectional view through a pack according to the invention.
• the rim 24 comprises a protruding flange extending from the upper edge of the side wall 14, at right angles thereto.
• the flange may be given rigidity so that it maintains its position under applied pressure by extending the flange continuously around corners of the pack, as in Figure IA.
• This embodiment offers a relatively simple construction, and also uses a minimum of material. However, tobacco 16 that occupies the space under the rim may be difficult to remove from the pack, or may be overlooked altogether.
• Figure 3B shows a second example embodiment of the rim 24, which addresses the above problem of tobacco 16 underneath the rim 24 of the first example.
• the rim 24 comprises a flange like that of the first example, but which is supported by a downwardly extending support member 26, which extends vertically between the inner edge of the flange and the upper surface of the lower face 28 of the receptacle.
• This give a strong structure similar to a box girder, giving rigidity to the pack and making it more resistant to crushing.
• tobacco cannot become trapped or hidden in the space under the rim.
• the presence of the support member 26 reduces the interior volume of the receptacle and hence the amount of tobacco that can be provided in the pack.
• Figure 3C shows a third example embodiment of the rim 24, which offers some of the increased strength of the second example, while increasing the available interior volume.
• the flange is supported by a sloping support member 30 that extends between the inner edge of the flange and the outer edge of the lower face 28, to make a triangular box girder structure.
• Figures 3A, 3B and 3C show the lid portion 20 spaced slightly apart from the abutment member 24, whereas in use, if the lid is securely closed and/or pressure is applied to the upper face 12, the lid portion 20 will likely contact the abutment member 24.
• the abutment member may have other structures than those illustrated.
• the rim may extend outwardly from the side walls rather than inwardly, if used in conjunction with an overhanging lid portion.
• the abutment member need not be continuous along the side walls as in Figure IA. Instead, one or more individual abutment members may be positioned separately at various locations along the side walls. Also, the abutment member may be omitted.
• the upper edges of the side walls may provide sufficient support and movement-limiting effect if the Hd portion extends over at least part of these upper edges.
• Packs according to the invention may further comprise a closure assembly by which the lid portion can be held in the closed position until the user desires to open the pack.
• a closure assembly by which the lid portion can be held in the closed position until the user desires to open the pack.
• a first example is illustrated in Figures IA and IB.
• One edge of the lid portion 20 has a recessed, cut-out portion 32a extending along the greater part of its length from the end adjacent to the hinge line 18. The remaining part of the edge, adjacent to the corner opposite the hinge line 18 is not cut out and forms a protruding portion 32b.
• the upper edge of the adjacent side wall is formed so as to have corresponding protruding and recessed portions.
• the greater part of the edge is a protruding portion 34a of the same length as the recessed portion 32a in the lid portion, and the remaining part of the edge, adjacent to the corner opposite the hinge line 18, is cut out to form a recessed portion 34b of the same length as the protruding portion 32b.
• the lid portion 20 When the lid portion 20 is brought into its closed position, the protruding portion 32b on the lid portion enters the recessed portion 34b on the side wall 14, and the protruding portion 34a on the side wall 14 enters the recessed portion 32a on the lid portion 20. Because the corresponding portions have substantially equal lengths, this interengagement produces an interference fit, and the lid portion 20 is held closed.
• protruding and recessed portions in Figure IA gives a small part of the Hd portion (the protruding portion 32b) located at the corner of the pack opposite the hinge line 18 that is accessible from the side wall 14. This portion can engaged using a finger or thumb, so that the lid portion 20 can be pushed upwards out of the interference fit closure and rotated about the hinge line 18 so as to open the pack. The pack can thereby conveniently be opened with one hand.
• other arrangements of engaging protruding and recessed portions can be used instead, although one-handed operation will be possible with at least some of the other possible configurations.
• the distance by which the recessed portions are recessed from the protruding portions is equal to the thickness of the material from which the portions are made. This means that when the lid portion is closed and the portions are interengaged, there are no discontinuities (protrusions or depressions) in the plane of the upper face 20. A substantially smooth upper face is provided, with no parts in which loose bits of tobacco could become caught. Also, the appearance of the pack is enhanced by the smooth outer surface.
• the protruding and recessed portions may have other dimensions, however, although the example of Figure 1 uses and wastes a minimum of material.
• Figures 4A and 4B show a second example of a closure assembly.
• the pack 60 is a square parallelepiped pack with a diagonal hinge line, as in Figures IA and IB.
• the closure assembly comprises a tab 36 extending from an edge of the lid portion 20.
• the tab 36 is angled downwardly with respect to the lid portion 20 so that when the lid portion 20 is in the closed position, the tab 36 can be tucked into a slot 38 in the adjacent side wall 14, as shown in Figure 4B.
• Figure 4A shows the pack 60 with the lid portion 20 in the open position. This example offers the same smooth continuous upper face as the first example.
• Packs according to the invention may further comprise a sealing layer (not shown) disposed under the lid portion 20 to seal the aperture which is exposed when the Hd portion 20 is opened.
• a sealing layer will keep the tobacco 16 in the pack fresh until the pack is first opened by a user.
• the sealing layer can be adhered to the edges of the aperture, for example adhered to the rim 24 or to the upper edges of the side walls 14, in such a way that it can be peeled off and disposed of by the user on first opening the pack.
• the sealing layer may be resealable, so that it can be stuck back down over the aperture to maintain freshness of the tobacco after the pack has been opened.
• the pack may be provided with a removable outer wrapper, for example a cellophane or plastic wrapper, that is removed on first opening the pack.
• the packs according to the invention can be fabricated from any suitable material and using any suitable technique.
• the packs can be assembled by folding and gluing one or more blanks of cardboard or stiff paper in the manner used to make conventional crush-proof cigarette packs.
• the packs can be made from plastics materials, for example by moulding, including injection moulding or thermo-forming.
• the shape of the pack may determine the choice of material and fabrication technique.
• the circular pack of Figure 2C may be simpler to make from plastics than from cardboard.
• the interengaging closure portions in Figure IA may also be found to be more conveniently implemented for a plastics pack.
• the packs are not limited to being packs for tobacco intended for the hand- rolling of cigarettes. Although many features of the packs are of particular use for cigarette rolling, other features such as the outer shape and rigidity being advantageous for packing, shipping, storing and vending are relevant for other tobacco products.
• the tobacco may be pipe tobacco, loose snus or portion snus.
