Definitions

  • the invention relates to a pack for smoking articles, such as cigarettes.
  • the invention relates to a hinged-lid pack for smoking articles.
  • packs for smoking articles are known.
  • One such pack is the so-called‘hinged-lid’ pack which generally comprises a base and a lid hingedly connected to a rear wall of the base and pivotable between an open position to allow access to the interior of the base through an access aperture in the top of the base, and a closed position in which the opening in the base is closed by the lid.
  • a container for smoking articles comprising a base and a lid hingedly connected to the base, the base having a pair of side walls and a front wall extending between the side walls that meets each side wall at an edge, wherein a row of teeth lying in the plane of the side and/or front wall extend from said edge.
  • the lid may also have a corresponding recess, or recesses, on an inner surface. If there is more than one recess, each recess may be configured to receive a respective tooth when the lid is closed. Alternatively, there may just be a single recess in which all the teeth locate when the lid is closed.
  • a row of teeth could extend from both edges, i.e. where the front wall meets each side wall of the pack, although it is possible that the row of teeth could extend from only a single edge of the pack.
  • the pack is symmetrical about its longitudinal axis so both edges are the same.
  • the row of teeth extending from an edge may lie in the plane of both the side wall and the front wall so both the front wall and the side wall of the lid may be engaged by the row of teeth.
  • teeth extending from an edge lie in the plane of both the front and the side wall, they can be configured so that they mesh with each other at each edge. More specifically, a tooth lying in one plane may be spaced from a tooth lying in the same plane by a tooth lying in the other plane, i.e. the tooth lying in the other plane is effectively positioned in the trough between the tooth lying in the same plane so that the direction in which adjacent teeth extend is alternating.
  • Each side wall and the front wall may lie at 90 degrees to each other. As the teeth lie in the plane of the front and side walls, the teeth lying in the plane of the side wall will then also be at 90 degrees to the teeth lying in the plane of the front wall.
  • the front and side walls can be formed from integrally from the same sheet of material.
  • the edge between each side wall and the front wall may be defined by a fold-line.
  • the teeth that extend from said edge in the plane of the side wall may be cut from the material that forms part of the front wall.
  • the lid of the container can comprise inner flaps that lie against an inner surface of the lid.
  • the recesses can then be formed from cut-outs extending along said edges.
  • the position of the cut-outs can correspond to the position of the teeth so that each tooth is received in a corresponding cut out when the lid is closed.
  • the teeth may make contact with the flaps during the action of closing the lid and continued movement of the lid into its fully closed position may then cause the teeth to produce an audible or tactile‘click’ type sensation as they drop into their respective recess.
  • the lid and/or the teeth may have a degree of resilience or‘give’ so that the pack flexes during closure to allow the teeth to positively locate in the appropriate recess.
  • edge of the inner flaps may be straight, but they may not extend all the way across the inside surface of the lid so that a gap is formed between the edge of the inner flap and the adjacent inside wall of the lid.
  • the teeth can then locate in this gap when the lid is closed, i.e. all the teeth extending in one direction from an edge will be received in the same recess.
  • the base may comprise an inner frame extending from the access opening.
  • the inner frame is then received in the lid when the lid is closed.
  • the teeth can then be formed in the inner frame.
  • the inner frame can be a separate component that is attached to the base during assembly.
  • the row of teeth may comprise a serrated profile.
  • the teeth may have pointed tips.
  • the row may have a zig-zag shaped profile.
  • the row of teeth may comprise a castellated profile.
  • each tooth may be essentially square-shaped or rectangular with two straight parallel side edges and a top edge extending at right-angles to each side edge.
  • an inner frame blank for a smoking article container that is configured to extend from a base of the container and be received within a lid hingedly connected to the base when the lid is closed, the inner frame blank having a pair of side walls and a front wall extending between the side walls that meets each side wall at an edge, wherein a plurality of teeth lying in the plane of the side and/or front wall extend from said edge when the inner frame is folded about said edge.
  • the edge can be defined by a fold-line that is broken part way along its length by a cut -line configured so that, when each side wall is folded relative to the front wall about said edge, the material separates along said cut-line.
  • the cut-line can have a toothed form that extends laterally from said edge.
  • the cut-line may have a toothed form that extends laterally from said edge in opposite directions so that a plurality of teeth lying in the plane of both the side and the front wall extend from said edge when the blank is folded about the fold-line.
  • a method of forming a pack for smoking articles from a sheet of material comprising a base and a lid hingedly connected to the base, the base having a pair of side walls and a front wall extending between the side walls that meets each side wall at an edge, said edge being partly defined by a toothed cut-line through the material so that, when the blank is subsequently folded about said edge, the material separates along said cut-line to form a row of teeth extending from each edge in the plane of the side wall and/or the front wall.
  • the toothed cut -line may be formed so that it extends laterally away from the edge in both directions into the side wall and the front wall.

  • Figures 1 and 2 each show a perspective view of a container in accordance with an embodiment of the invention.
  • the container is described in terms of a pack 1 for containing smoking articles.
  • the term“smoking article” includes smokeable products such as cigarettes, cigars and cigarillos whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also heat-not-burn products.
  • the pack 1 includes a base 2 and a lid 3.
  • the lid 3 is attached to the base 2 for rotation about hinge 4 on the rear wall and spaced from the top of the pack in order to allow the pack 1 to be opened and closed.
  • the pack 1 is shown in its open state.
  • the base 2 includes front and back panels 5, 6, two opposing side panels 7, 8, and a closed bottom panel 9.
  • the lid 3 is at the top of the pack 1, opposite the closed bottom panel 9.
  • the lid 3 includes a front panel 10, two opposing side panels 11, 12 and a top panel 10a.
  • the lower edge 10a of the front panel 10 of the lid 3 aligns with and abuts the upper edge 5a of the front panel 5 of the base 2, while the lower edges 11a, 12a of each opposing side panel 11, 12 aligns with and abuts the upper edge 7a, 8a of each of the two opposing side panels 7, 8 of the base 2.
  • a blank for forming the pack l shown in Figure l is illustrated in Figure 3 and in which lines about which adjacent panels or walls are folded are represented by dashed lines and lines which are cut are represented by solid lines.
  • An inner frame 13 is attached to the inside of, and extends from, the open end of the base 2 and has a front wall 14 and opposing side walls 15, 16.
  • the front wall 14 meets each side wall 15, 16 at an edge 18 defined by a fold line.
  • the side walls 15, 16 are parallel to each other and extend at right angles to the front wall 14 when the inner frame 13 is folded and inserted into the base 2.
  • the inner frame 13 is received in the lid 3 when the lid 3 is closed and so that a front wall inner flap 21 of the lid 3 lies against the front wall 14 of the inner frame 13.
  • side wall inner flaps 22 of the lid 3 lie against the side walls 15, 16 of the inner frame 13.
  • a blank for forming the inner frame 13 is illustrated in Figure 6.
  • the edge 18 of the inner frame 13, where the front wall 14 meets each of the side walls 15, 16 is provided with a feature to help maintain the lid 3 in a closed state.
  • the feature in conjunction with corresponding features in the lid, may alternatively or additionally provide tactile and/ audible feedback to a consumer when the lid 3 is opened and closed, and may provide the consumer with positive reassurance that the lid 3 will remain in its closed state.
  • the feature comprises a line or row of teeth, such as serrations 19, which protrude from the edge of the inner frame 13 and lie in the same plane as the sidewall 15, 16 and/or the front wall 14 when the pack is assembled. More specifically, in one embodiment, serrations 19 extend from one or, more preferably, both of the side walls 15, 16 and protrude beyond the plane of the front wall 14 at right angles to the front wall 14. Alternatively, serrations 19 extend from the front wall 14 at right angles to the side walls 15, 16 and protrude beyond the plane of the side walls 15,16.
  • serrations 19 extend from both the side walls 15,16 and from the front wall 14, as shown most clearly in Figure 2, and from which it can be seen that the serrations 19 mesh, dovetail or interlock with each other so that a serration 19a extending from a side wall 15,16 is adjacent to a corresponding serration 19b extending from the front wall 14. More specifically, each serration 19a lying in a first plane is spaced from its adjacent serration 19a in the same plane by a serration 19b lying in a second plane at right angles to the first plane. If each set of serrations 19 are defined as having peaks and troughs, then the serration 19a lying in the second plane lies in the trough between the serration 19b lying in the first plane. The direction in which adjacent serrations 19 extend therefore alternates.
  • the serrations 19 may be formed as tooth-like projections or tangs and resemble a saw-tooth like profile. In particular, they may have pointed tips and may each define the shape of an isosceles triangle. Alternatively, they may have the shape of a right-angled triangle or take some other form or profile.
  • Corresponding recesses 20, can be formed on the inner surface of the lid 3 so that, when the lid 3 is closed, each serration 19 locates in its
  • the serrations 19a extending from each side wall 15,16 may make initial contact with a front wall inner flap 21 lying against the inner surface 23 of the front wall 10 and serrations 19b extending from the front wall 14 may make initial contact with a side wall inner flap 22 lying against each of the inner surfaces 24 of the side walls 11,12 of of lid 3 before they ‘click’ or slide across the inner flaps 21,22 into the recesses 20 when the lid 3 is fully closed.
  • the tips of the serrations 19a may then extend through the recesses 20 and he in contact with the inner surface 23 of the front wall of the lid 3 and serrations 19b may he in contact with the inner surface 24 of the side walls 15,16 of the lid 3, to help maintain the lid 3 in the closed position.
  • the front wall inner flap 21 is folded and glued so that it lies against the inner surface 23 of the lid front panel 10 when the pack 1 is assembled.
  • the side wall inner flaps 22 are also folded and glued so that each side wall inner flap 22 lies against an inner surface 24 of its corresponding side wall 11,12 when the pack 1 is assembled.
  • Edges of one or both of the front and/or side panel inner flaps 21, 22 have cut-outs 20a or serrated edges so that, when the flaps 21, 22 are in their assembled positions, they form the recesses 20 in which the serrationsi9 are received when the lid 3 is closed, with the inner surfaces 23, 24 of the lid 3 forming base of the recesses 20.
  • the recesses 20 can be formed by embossing or by forming ridges (not shown) on an inner surface of the lid 3 or flap.
  • the serrations 19 are formed by initially forming an upper fold line 25a extending from the top edge of the inner frame 13 and a lower fold line 25b extending upwardly from the bottom edge of the inner frame 13 towards the upper fold line 25a.
  • the first and second fold lines 25a, 25b are then connected by cutting a serrated, zig-zag or saw-tooth shaped slit 26 in the inner frame 13 that extends between the upper and lower fold lines 25a, 25b.
  • the inner frame 13 is then folded about the fold lines 25a, 25b, the intermeshing serrations 19 are formed. It will be appreciated that the serrations 19a extending from the side walls 15,16 are cut out from the front wall 14 and the serrations 19b extending from the front wall 14 are cut out from the side wall 15,16.
  • FIGS 4 and 5 show an alternative pack 1 according to an embodiment of the invention.
  • This embodiment is identical to the previous embodiment, except that neither the front wall inner flap 21 or the side wall inner flaps 22 are provided with individual cut-outs along their edges 31, 32 to receive the serrations 19.
  • the side edge 31 of the front wall inner flap 21 does not extend all the way to the fold between the front wall 10 and each of the side walls 11, 12.

  • each row of teeth 30 extend in the plane of the front wall 14 of the pack 1 beyond their corresponding side wall 15, 16. However, they could also extend in the plane of the side wall 15,16.
  • Figure 7A shows an enlarged view of the row of teeth 30 visible in Figure 7, and from which it can be seen that each tooth 31 has a curved or arcuate peripheral edge. Each tooth 31 may be semi-circular in shape.
  • Figure 7B shows an alternate form for the serrations 19 of Figures 4 and 6, and Figure 7C shows a square-shaped, stepped or castellated profile in which each tooth 32 has parallel edges 32a and a top edge 32b extending at right angles to the edges 32a.
  • Figure 8 illustrates a possible form for the recesses in the inner surface of the lid 3.
  • the recesses may be formed in a lid flap or directly in the side wall of the lid 3. Furthermore, they may comprise a series of indentations or curved depressions 34.
