Definitions

• Such containers typically have a substantially parallelepiped shape comprising two-dimensional walls, including a front wall, a rear wall, two side walls, a top wall and a bottom wall. The manufacture of such containers using high speed manufacturing machines and processes is well established.
• US 2004/0035723 A1 describes a method for manufacturing different cigarette containers having a variety of non- planar front walls.
• the method described in US 2004/0035723 A1 requires the use of a complex deformation device to modify the front wall of the container in a separate process after the container has been assembled.
• a container for consumer goods comprising a complex shape that can be assembled using existing high speed manufacturing machines and processes with minimal modification. It would be particularly desirable to provide such a container with at least one three-dimensional wall.
• a first side wall extends between the first top wall side edge and the first bottom wall side edge, the first side wall being connected to the front wall by a first side wall front edge and the first side wall being connected to the rear wall by a first side wall rear edge.
• a second side wall extends between the second top wall side edge and the second bottom wall side edge, the second side wall being connected to the front wall by a second side wall front edge, and the second side wall being connected to the rear wall by a second side wall rear edge.
• the top wall front edge, the bottom wall front edge, the first side wall front edge, and the second side wall front edge together extend along a first plane.
• the top wall rear edge, the bottom wall rear edge, the first side wall rear edge, and the second side wall rear edge together extend along a second plane.
• At least one of the front wall and the rear wall comprises an ablation area, wherein any ablation area on the front wall comprises at least one ablated line extending across the inner surface of the front wall to define a portion of the front wall that is spaced outwardly from the first plane, and wherein any ablation area on the rear wall comprises at least one ablated line extending across the inner surface of the rear wall to define a portion of the rear wall that is spaced outwardly from the second plane.
• Each ablated line has a residual thickness (RT1 ) that is less than the thickness (T) of the laminar blank.
• the terms “side”, “top”, “bottom”, “front”, “rear” and other terms used to describe relative positions of the components of containers according to the invention refer to the container in an upright position with the lid portion, where present, at the top.
• these terms are used irrespective of the orientation of the container being described.
• the hinge line is located at the back of the container and allows opening of the lid portion by a pivotal movement about the hinge line.
• panel is used herein to refer to a portion of the containerformed from a single, continuous portion of material. A panel may depend from one or more other panels.
• overlap refers to a panel that depends from only one other panel.
• wall refers more generally to a facet of the container, and a wall may be formed from a single panel or flap, or a wall may be formed from two or more abutting or overlapping panels or flaps.
• ablated line is used herein to refer to an area of the blank from which material has been ablated (removed by means of a laser beam or a blade, for example) from a surface of the laminar blank or container. Accordingly, the residual thickness of an ablated line is less than the thickness (T) of the laminar blank.
• an ablated line is provided as a groove within the blank. This may be formed with a linear ablation tool, such as a laser or a blade and preferably is a laser. Laser ablation may be performed using any suitable equipment, preferably a 1000 Watt carbon dioxide laser as commercially available from DIAMOND, such as the E-1000, for example. Ablation may be performed in the machine direction of the laminar blank or the cross direction.
• the "thickness" (T) of the blank is the thickness of the blank after it has been manufactured, but before any ablation lines or creasing lines have been formed in the blank. That is, the thickness (T) of the blank is the thickness in any region of the blank not containing an ablated line or a crease line.
• residual thickness is used herein to refer to the minimum distance measured between two opposite surfaces of the laminar blank or a panel of the container formed from the blank. In practice, the distance at a given location is measured along a direction locally perpendicular to the opposite surfaces.
• the residual thickness of each ablated line can be determined by using an Optical Profilometer for 2D Non-Contact Surface Metrology, such as the MicroSpyTM Profile commercially available from Fries Research & Technology GmbH, Bergisch Gladbach, Germany, or a 3D laser scanning confocal microscope, such as the VK- X series of microscopes commercially available from Keyence Corporation of America, New Jersey, United States of America.
• the points of residual thickness are measured over the length of an ablated line, wherein the points of measurement are evenly spread over the length of one ablated line and the arithmetic mean is calculated. More preferably, to obtain the residual thickness according to the present invention, five measurements, evenly spread over the length of an ablated line, are performed and then the arithmetic mean is calculated.
• the residual thickness is measured at both ends of the ablated line and at three further points distanced 20 millimetres, 40 millimetres and 60 millimetres respectively from one end of the ablated line, preferably from the lower end of the ablated line.
• the "residual thickness" of an ablated line may be constant over the ablated line if material is removed homogenously substantially all over the ablated line (flat profile). Alternatively, the residual thickness of the ablated line may vary across a width of the ablated line, if material is removed non-homogeneously over the ablated line (e.g. V-shaped, U- shaped grooves).
• containers according to the present invention comprise a front wall, a rear wall, or both a front wall and a rear wall comprising a portion that is spaced outwardly from a plane defined by the edges bounding the wall. That is, in containers according to the present invention, at least one of the front wall and the back wall is three-dimensional.
• containers according to the present invention can be formed on existing high speed manufacturing machines with minimal modification.
• the three-dimensional features of at least one of the front wall and the rear wall are formed automatically by virtue of the normal folding forces that are applied to the blank during manufacture of the container. That is, folding the blank to create the edges bounding the front wall, the rear wall, the top wall, the bottom wall and the side walls automatically deforms the blank along the ablated lines of the ablation areas so that no further processes are required to form the three-dimensional features of the front wall, the rear wall, or the front wall and the rear wall.
• the blank can be adapted easily to form containers having different shapes without the need for major modifications of the packing machine used to assemble and pack the container.
• Forming the ablated lines by removing material from the surface of the blank that forms an inner surface of the container advantageously maintains a smooth outer surface of the container, which may provide a desirable appearance of the container upon visual and tactile inspection.
• At least one ablated line of any ablation area on the front wall preferably extends from at least one of the top wall front edge, the bottom wall front edge, the first side wall front edge, and the second side wall front edge.
• at least one ablated line of any ablation area on the rear wall preferably extends from at least one of the top wall rear edge, the bottom wall rear edge, the first side wall rear edge, and the second side wall rear edge.
• forming an ablated line extending from an intersection between two edges of a wall may further enhance the effect of transferring at least some of the folding force along the ablated line when the blank is folded to form the container. Therefore, preferably, at least one ablated line of any ablation area on the front wall extends from an intersection of one of the top wall front edge and the bottom wall front edge with either the first side wall front edge or the second side wall front edge. Similarly, at least one ablated line of any ablation area on the rear wall preferably extends from an intersection of one of the top wall rear edge and the bottom wall rear edge with either the first side wall rear edge or the second side wall rear edge.
• each ablated line preferably has a residual thickness (RT) of at least about 5 percent, more preferably at least about 10 percent, more preferably at least about 15 percent, more preferably at least about 20 percent, more preferably at least about 25 percent and even more preferably at least about 30 percent of the thickness (T) of the blank.
• each ablated line preferably has a residual thickness of less than about 50 percent, more preferably less than about 45 percent and even more preferably less than about 40 percent of the thickness (T) of the blank.
• the laminar blank preferably has a basis weight of between about 100 grams per square metre and about 350 grams per square metre, more preferably between about 150 grams per square metre and about 350 grams per square metre, more preferably between about 200 grams per square metre and about 300 grams per square metre.
• Basis weight is calculated using ISO 536 and may vary from plus ten percent to minus ten percent, preferably from plus five percent to minus five percent.
• a sample of the portion to be tested should first be removed from the laminar blank.
• the spring-back force of a pack is assessed using a sample measuring 38 ⁇ 1 millimetres by 38 ⁇ 0.5 millimetres, with the corner forming portion being positioned 21 ⁇ 0.5 millimetres from one side of the blank.
• the blank should be conditioned at 22 degrees Celsius and 60 percent relative humidity for at least 24 hours prior to testing.
• the laminar blank is preferably a cellulose- fibre-based laminar blank.
• a cellulose-fibre-based blank comprises at least 50 weight-percent cellulose, preferably wood fibres, based on the total fibre content of the laminar blank.
• a cellulose-fibre-based laminar blank may include other types of fibres, such as polymer fibres.
• the container may comprise a box portion and a lid portion depending along a hinge line from a top edge of the box portion, the lid portion being moveable about the hinge line between an open position and a closed position.
• the lid portion comprises a lid portion top wall, a lid portion front wall, a lid portion rear wall, a first lid portion side wall and a second lid portion side wall.
• the box portion comprises a box portion front wall, a box portion rear wall, a box portion bottom wall, a first box portion side wall and a second box portion side wall.
• the lid portion top wall forms the container top wall and the box portion bottom wall forms the container bottom wall.
• the lid portion and box portion front walls together form the container front wall
• the lid portion and box portion rear walls together form the container rear wall.
• a bottom edge of the lid portion rear wall depends along the hinge line from a top edge of the box portion rear wall.
• the first lid portion and box portion side walls together form the container first side wall
• the second lid portion and box portion side walls together form the container second side wall.
• the laminar blank further comprises at least one ablation area so that at least one of the front wall and the rear wall of the container comprises the at least one ablation area, wherein any ablation area on the front wall comprises at least one ablated line extending across the inner surface of the front wall, and wherein any ablation area on the rear wall comprises at least one ablated line extending across the inner surface of the rear wall.
• Each ablated line has a residual thickness (RT1 ) that is less than the thickness (T) of the laminar blank.
