Definitions

• the present invention relates to a container for consumer goods and a laminar blank for forming a container for consumer goods.
• the invention finds particular application as a container for elongate smoking articles, such as cigarettes.
• the container in which the consumer goods are packaged provides a means for communicating with the consumer.
• manufacturers typically use a combination of graphics and text applied to one or more surfaces of the container to communicate information to the consumer.
• a container for consumer goods comprising a box portion and a lid portion both formed from a single laminar blank.
• the lid portion comprises a lid portion back wall depending from a box portion back wall, a lid portion top wall depending from the lid portion back wall, and a lid portion front wall depending from the lid portion top wall.

• the lid portion comprises first and second lid portion side walls, wherein each lid portion side wall comprises one of each of the first, second and third lid portion side flaps.
• panel is used herein to refer to a portion of the container formed from a single, continuous portion of material. A panel may depend from one or more other panels. The term “flap” refers to a panel that depends from only one other panel.
• Conventional containers such as hinge-lid containers typically used for storing smoking articles, comprise "dust flaps" depending from lid portion side walls and underlying a lid portion top panel to form part of a lid portion top wall.
• the dust flaps can minimise ingress or egress of material into or out of the container between the lid portion top wall and the lid portion side walls.
• the inner surface of the lid portion top wall of conventional containers is non-uniform.
• the inner surface of the lid portion top wall of conventional containers at least comprises a join where the ends of the dust flaps abut each other.
• the combined width of the dust flaps is less than the width of the lid portion top panel such that the ends of the dust flaps do not abut and a gap is formed therebetween.
• the surface height of the lid portion top wall inner surface is nonuniform.
• Such non-uniformity makes it difficult to apply, for example, an indicia to the inner surface of the lid portion top wall.
• printing onto the inner surface after the lid portion top wall has been formed is difficult due to the non-uniformity of the surface and the difficulty in accessing the inner surface of the lid portion top wall after the lid portion has been formed.
• containers according to the present invention include a lid portion comprising first, second and third lid portion side flaps forming each of the lid portion side walls.
• the second lid portion side flaps depend from the lid portion top wall and function as dust flaps to minimise ingress or egress of material into or out of the container between the lid portion top wall and the lid portion side walls.
• containers according to the present invention can be more easily formed with a uniform inner surface of the lid portion top wall.
• the inner surface of the lid portion top wall of containers according to the present invention can therefore be more suitable for use in communicating with a consumer than the inner surface of the lid portion top wall of conventional containers comprising dust flaps forming part of the inner surface of the lid portion top wall.
• a line of weakening may be a fold line in the laminar blank.
• the line of weakening may be formed when the laminar blank is folded to create the fold line.
• the line of weakening may be formed in the laminar blank before the laminar blank is folded along the line of weakening.
• the line of weakening may be a scoring line or a perforation line, for example.
• a wall, panel or flap may depend along a single line of weakening from an adjacent wall panel or flap, wherein the laminar blank is typically folded along the single line of weakening at an angle of approximately 90 degrees.
• a wall, panel or flap may depend along multiple lines of weakening from an adjacent wall, panel or flap.
• multiple parallel and coextensive lines of weakening may be formed in a laminar blank so that, when the laminar blank is folded along the multiple lines of weakening, a substantially rounded or bevelled edge is formed between the adjacent walls, panels or flaps.
• multiple overlapping but staggered lines of weakening may be formed in a laminar blank so that, when the laminar blank is folded along the multiple lines of weakening, a twisted edge is formed between the adjacent walls, panels or flaps.
• walls, panels and flaps may depend from adjacent walls, panels and flaps along a weakening strip.
• material may be removed from a surface of the laminar blank using an ablation tool, such as a laser or a blade.
• the portion of the blank from which the material is removed forms a weakening strip along which it may be easier to deform the blank when the blank is converted into the container.
• the multiple weakening lines may be replaced with a weakening strip having a width corresponding to the total width between the first and last multiple weakening lines.
• weakening zone is used herein to encompass lines of weakening, including fold lines, scoring lines and perforation lines, and weakening strips, including ablated areas on the blank.
• inner surface is used herein to refer to a surface of a wall, panel or flap that faces towards the interior of the container, for example towards the consumer goods, when the lid portion is closed. Thus, an inner surface is not directly visible to the consumer when the lid portion is closed.
• outer surface is used herein to refer to a surface of a wall, panel or flap that faces towards the exterior of the container.
• containers according to the present invention advantageously comprise second lid portion side flaps that form dust flaps on the lid portion side walls rather than the lid portion top wall, which can result in an inner surface of the lid portion top wall that is more suitable for use in communicating with a consumer.
• the lid portion top wall comprises an inner surface extending between the lid portion side walls, the lid portion back wall and the lid portion front wall, and wherein substantially the whole lid portion top wall inner surface forms part of an inner surface of the container.
• substantially the whole inner surface of a lid portion top wall to form part of the inner surface of the container can optimise the suitability of the lid portion top wall inner surface for communicating with a consumer.
• substantially the whole inner surface of the lid portion top wall is a continuous and uniform surface.
• the lid portion top wall may comprise a lid portion top panel depending from the lid portion back wall.
• the lid portion top panel may define the inner surface of the lid portion top wall.
• Each of the lid portion front wall and the second lid portion side flaps depend from the lid portion top panel.
• the lid portion top wall consists only of a single lid portion top panel depending from the lid portion back wall, and wherein each of the lid portion front wall and the second lid portion side flaps depend from the single lid portion top panel.

That is, the lid portion top wall 130 of the container 100 according to the present invention does not comprise any dust flaps. Accordingly, the inner surface of the lid portion top wall 130 is uniform over its entire area and may therefore be suitable for use in communicating with a consumer.
• an indicia 102 such as a printed graphic, may be applied to the inner surface of the lid portion top wall 130.
• the container 100 according to the present invention incorporates lid portion dust flaps into the first and second lid portion side walls 134, 136, as shown more clearly in Figure 5, which shows a laminar blank 150 for forming the container 100 according to the present invention.
• the laminar blank 150 for forming the container 100 according to the present invention is substantially the same as the laminar blank 50 for forming the prior art container 10, and therefore like reference numerals are used to designate like parts.
• the difference between the laminar blank 150 and the prior art laminar blank 50 is the position of the lid portion dust flaps.
• the laminar blank 150 comprises second lid portion side flaps 138 depending along fold lines 194 from the lid portion top panel 42, the second lid portion side flaps 138 forming lid portion dust flaps that depend from the lid portion top wall 130 and form part of the lid portion side walls 134, 136.
• This is in contrast to the prior art container 10, in which the lid portion dust flaps 38, 40 depend from the lid portion side walls 34, 36 and form part of the lid portion top wall 30.
• the respective first, second and third lid portion side flaps 88, 138, 96 overlap each other to form the first and second lid portion side walls 134. Since the second lid portion side flaps 138 have a square shape, rather than the trapezoidal shape of the first and third lid portion side flaps 88, 96, the second lid portion side flaps 138 may extend below the bottom edges of the first and third lid portion side flaps 88, 96 when the laminar blank 150 is folded.
• the laminar blank 150 is preferably folded so that each second lid portion side flap 138 underlies both of the respective first and third lid portion side flaps 88, 96, which ensures that the second lid portion side flaps 138 do not abut edges of the first and second box portion side panels 62, 66 as the lid portion 12 is moved into the closed position.
• FIG. 6 shows an alternative laminar blank 250 for forming the container 100 according to the present invention.
• the laminar blank 250 is substantially the same as the laminar blank 150 shown in Figure 5, but with the addition of two cut-outs 252 in the blank 250 which create second lid portion side flaps 238 having the same trapezoidal shape as the first and third lid portion side flaps 88, 96. Therefore, the first, second and third lid portion side flaps 88, 238, 96 can overlie or underlie each other in any order.
• FIG. 7 shows an alternative laminar blank 350 for forming the container 100 according to the present invention.
• the laminar blank 350 is substantially the same as the laminar blank 250 shown in Figure 6, but with the two cut-outs 352 extended between each second lid portion side flap 338 and the respective first and third lid portion side flaps 88, 96.
• Removing material between each second lid portion side flap 338 and the respective first and third lid portion side flaps 88, 96 can advantageously facilitate folding of the first, second and third lid portion side flaps 88, 338, 96 to form the lid portion side walls.
• FIG 8 shows an alternative laminar blank 450 for forming the container 100 according to the present invention.
• the laminar blank 450 is substantially the same as the laminar blank 350 shown in Figure 7, but additionally includes a lid portion top wall under panel 85 depending along a fold line 87 from the lid portion front wall under panel 84.
• the under panels 84 and 85 are first folded about fold line 86, so that under panels 84 and 85 underlie their respective lid portion panels 80 and 42. Adhesive may be provided between panels 80 and 84 to secure them together, after the blank has been folded about fold line 86. The blank is then folded about fold lines 87 and 82, so that the lid portion front wall (formed by panels 80 and 84) is orthogonal to the lid portion top wall (formed by panels 85 and 42).
• Adhesive may be provided between panels 42 and 85; however, it is preferable for no adhesive to be provided between these panels so that they can move relative to one another when the blank is folded about fold lines 87 and 82.
• the blank can then be folded along fold line 78 so that the lid portion top wall (formed by panels 85 and 42) is orthogonal to the lid portion back wall (formed by panel 74).
• first, second and third lid portion side flaps 88, 338 and 96 can then be folded to form the lid portion side walls.
• the lid portion side walls it is preferable for the lid portion side walls to be formed, such that each first lid portion side flap 88 defines the inner surface of its respective lid portion side wall, each third lid portion side flap 96 defines the outer surface of its respective lid portion side wall, and each second lid portion side flap 338 is positioned between its respective first lid portion side flap 88 and third lid portion side flap 96.
• Adhesive may be used to secure the lid portions side flaps together on their respective lid portion side wall.
