Definitions

• the present invention relates to a container for consumer goods and to a blank for forming such container, which find particular application for holding elongate consumer goods, such as smoking articles (for example, cigarettes).
• Smoking articles are typically packaged in rigid hinge lid containers formed from folded laminar blanks.
• elongate smoking articles such as cigarettes and cigars
• rigid box-shaped containers such as hinge lid containers having a box portion and a lid connected to the box about a hinge line extending across the back wall of the container.
• the lid is pivoted about the hinge line to open the pack and so gain access to the consumer articles held in the box.
• a consumer in order to access the smoking articles or other consumer goods, a consumer typically holds the box portion in one hand and uses the other hand to pivot the lid portion about the hinge line and to remove a smoking article from the box portion.
• Such packs are typically constructed from one-piece laminar cardboard blanks.
• the containerfurther comprises a reinforcement innerframe at least partly wrapped around the consumer articles. This may provide further rigidity to the container and protect the consumer articles. Further, when the lid is in the closed position, an innerframe extending beyond the upper edge of the box front wall makes it easier for the lid front wall to align with the box front wall, such that the container presents to the consumer a substantially flat front surface.
• Hinge lid containers may sometimes suffer from problems such as the lid and the box portion not aligning correctly due to distortion of the lid, such that a gap becomes visible on the front of the container between the lid and the box portion. This is sometimes referred to as "smiling" effect.
• the degree to which smiling occurs usually increases with extended use of the package.

• the lid blank portion 404 comprises a front wall panel 414, a rear wall panel 418 and a top wall panel 420.
• Two side wall panels 416 extend from the front wall panel 414
• two side wall panels 417 extend from the rear wall panel 418
• lid dust flaps 419 extend from the side wall panels 417.
• the front wall panel 414 forms the container front wall
• the rear wall panel 418 forms the container rear wall
• the side wall panels 416, 417 overlap to form right and left container side walls
• the lid dust flaps 419 overlap top wall panel 420 to form the lid top wall.
• the side wall panels 416, 417 are substantially the same size and shape as each other.
• the panels 416, 417 directly overlie each other with their free edges substantially aligned, such that the inner side wall panel is barely visible.
• the lid dust flaps 419 are smaller than the top wall panel 420. When the container is formed, the lid dust flaps 419 lie inside the top wall panel 420. They provide additional structural support for the container (lid) top wall, but are not visible from the outside of the container.
• the blank 400 can be fed into a conventional packing machine for forming a parallelepiped hinged lid container.
• the front wall panel 414 of the lid blank portion 404 is forforming a lid front wall of the assembled container.
• the lid blank portion 404 further comprises a lid flap panel 425 depending from the front wall panel 414 along an edge fold line 426.
• a first magnetic material 430 is applied on the first laminar blank 400 over a portion of the lid flap panel 425 by gravure printing.
