- the present invention involves the removal of material from specific locations within the portion of the blank that defines a first edge portion of the container.
- ablation areas including ablated (for example, by laser ablation) lines to form the first edge portion of the container advantageously reduces the force required for folding the blank about the first edge portion.

- the container can be conveniently formed from a single blank by a conventional packing machine.
- the outer surface of the blank is unaffected by the ablation process, the resulting outer surface of the container does not exhibit localised ridges or ripples at the ablation line location (as would be the case with mechanical creasing lines).
- the blank of the present invention may advantageously be manufactured by precisely removing material from the first edge portion with a linear ablation tool (for example, a laser or a blade).
- a linear ablation tool for example, a laser or a blade.
- a laser is a particularly preferred ablation tool, as it is non-invasive and can be digitally programmed for improved flexibility of design.
- use of a laser as the ablation tool can allow for a wide variety of ablation profiles and configurations, with minimal adjustment of the laser tool being needed. Repeated passages of the ablation tool over a given portion of the blank results in the removal of a greater percentage of material, that is in a reduced residual thickness.
- Laser ablation may be obtained using any suitable equipment, preferably a 1000 Watt CO2 laser as commercially available from DIAMOND, e.g. the E-1000. Ablation may be obtained in machine direction of the laminar blank or in cross direction.

- minimum residual thickness is used herein to refer to the smallest value of “residual thickness” measured in an ablated line.
- the terms “front”, “back”, “upper”, “lower”, “top”, “bottom” and “side”, refer to the relative positions of portions of containers according to the invention and components thereof when the container is in an upright position with the access opening at the top of the container.
- the container is a hinged lid container

- the ratio of the width of the container to the depth of the container is in between about 0.3 to 1 and about 10 to 1, more preferably between about 2 to 1 and about 8 to 1, most preferably between about 2 to 1 and 3 to 1.
- the ratio of the height of the lid back wall to the height of the box back wall of the outer sleeve is between about 0 to 1 (lid located at the top edge of the container) to about 1 to 1, more preferably, between about 1 to 5 and about 1 to 10, most preferably, between about 1 to 6 to about 1 to 8.
- the ratio of the height of the lid front wall of the outer sleeve to the height of the box front wall of the outer sleeve is between about 1 to 0 (lid covering the entire front wall) to about 1 to 10, more preferably, between about 1 to 1 and about 1 to 5, most preferably, between about 1 to 2 and about 1 to 3.
- the exterior surfaces of containers according to the invention may be printed, embossed, debossed or otherwise embellished with manufacturer or brand logos, trade marks, slogans and other consumer information and indicia.
- Containers according to the invention may be filled and assembled using conventional apparatus and methods, modified to include the step of forming two or more ablated lines in the blank.
- the ablated lines may be produced using an ablation tool, such as a laser or a blade.
- a laser is particularly preferred as the ablation tool as it can allow for a wide variety of ablation profiles and configurations, with minimal adjustment of the laser tool being needed.
- the laser may be repeatedly passed over a given portion of the blank to iteratively remove different amounts of material, allowing for a very finely controlled ablation profile. It is also beneficial if fine ablated lines are required, with narrow widths. It is possible to accurately control the relative movement of the laser and the blank so as to form any type of pattern with varying removal intensity (“depth”) over the ablation area.
- FIG. 1 depicts a perspective view of a container having at least one edge portion according to an embodiment of the present invention
- FIG. 2 depicts a cross-sectional view of a portion of the laminar blank for forming the container of FIG. 1 , shown in an unfolded condition;
- FIG. 3 depicts a cross-sectional view of a portion of the laminar blank for forming the container of FIG. 1 , shown in a folded condition;
- FIG. 1 shows a container 100 for consumer goods, which can be formed by folding a cardboard or paperboard laminar blank having a thickness (T).
- the container 100 is a substantially rectangular parallelepiped in shape and comprises a box portion 30 and a hinge lid 40 connected to the box portion 30 along a hinge line 50 extending across the back wall of the container 100 .
- the overall size and construction of the box 30 and lid 40 of the container 100 is substantially the same as those of a standard hinge lid cigarette pack.
- the box portion 30 comprises a box front wall, a box back wall, a box bottom wall, a box left side wall and a box right side wall.
- the hinge lid 40 comprises a lid front wall, a lid back wall, a lid top wall, a lid left side wall and a lid left side wall.
- the hinge lid 40 is pivotable about the hinge line 50 between a closed position and an open position.
- the hinge lid 40 cover an access opening of the container 100 and the walls of the hinge lid 40 form extensions of the corresponding walls of the box portion 30 .
- the hinge lid 40 pivots about the hinge line 50 to project backwardly from the box portion 30 and the access opening at the top end of the box portion 30 be fully uncovered.
- the box portion 30 and the hinge lid 40 may be formed together from a single laminar blank having a thickness T.
- the container may be assembled from the laminar blank and filled using standard apparatus.
- the container comprises a first planar wall 4 , which in FIG. 1 is a side wall of the box portion 30 .
- the container also comprises a second planar wall 8 , which in FIG. 1 is the front wall of the box portion 30 .
- the side wall 4 and the front wall 8 are connected to each other by a first edge portion 20 , which is shown in FIG. 1 as a bevelled edge portion 20 .
- the inner surface of the bevelled edge portion 20 comprises first and second ablation lines that each define respective turning points 22 and 24 of the bevelled edge portion, when the container 100 is assembled.
- the turning points 22 and 24 extend in parallel with one another in the longitudinal direction of the bevelled edge portion 20 , to thereby define a single rectangular facet 6 of the bevelled edge portion 20 .
- the laminar blank therefore transitions from the side wall 4 to the facet 6 by an angle ( 22 ⁇ ) about the first ablation line defining turning point 22 .
- the first ablation line should therefore be designed to have a minimum residual thickness (RT) of from about 15 percent to about 40 percent of the thickness (T) of the laminar blank, and an ablated width (X) as measured transversely to the longitudinal direction of the first edge portion, such that the angle ( 22 ⁇ ) is within five degrees of:
- the laminar blank transitions from the facet 6 to the front wall 8 by an angle ( 24 ⁇ ) about the second ablation line defining turning point 24 .
- the second ablation line should therefore be designed to have a minimum residual thickness (RT) of from about 15 percent to about 40 percent of the thickness (T) of the laminar blank, and an ablated width (X) as measured transversely to the longitudinal direction of the first edge portion, such that the angle ( 24 ⁇ ) is within five degrees of:
- FIGS. 2 and 3 show cross sectional views of the first edge portion 20 in an unfolded and folded condition respectively.
- FIG. 2 shows the laminar blank in an unfolded substantially flat condition, with the first ablation line 220 and the second ablation line 240 being substantially V-shaped in their cross-sectional profile.
- FIG. 3 shows the blank in a folded condition, whereby the side walls of each ablation groove's 240 , 220 sidewalls have been brought together to abut one another.
- the blank has been folded such that an angle 24 ⁇ exists between the outer surface of the front wall 8 and the facet 6 , and an angle 22 ⁇ exists between the outer surface of the side wall 4 and the facet 6 .
- the bevelled edge portion 20 can have an improved strength and be less vulnerable to local deformation.
- FIGS. 2 and 3 are provided purely for illustrative purposes, and it will be appreciated that are they are not necessarily schematically accurate or to scale.
