Lid corner with internal layer cutout shape

A container, the container comprising a box, a lid for the box, and a lock to maintain the lid in a closed position,

• the box comprising a base, sidewalls and an opening opposite the base,
• the lid comprising a top and flanks,
• the top covering the opening and the flanks covering at least a portion of the sidewalls of the box when the lid is in the closed position,
• whereby the flanks comprise at least a first and a second flank,
• whereby the first and the second flanks intersect at a first corner segment along a corner direction normal to the top, the first corner segment comprising a first external layer folded along the corner direction and a first internal layer folded along the corner direction,
• whereby the first external layer and the first internal layer are cardboard or paperboard,
• whereby the first external layer overlaps the first internal layer at the first corner segment,
• whereby the first external layer is connected to the first internal layer along a first longitudinal fold line parallel to the first flank and along a second longitudinal fold line parallel to the second flank, the first and the second longitudinal fold lines defining respective distal ends of the first and second flank away from the top,
• whereby the first internal layer and the first external layer are attached to each other at least a point situated between the longitudinal fold lines and the top of the lid,
• whereby the first external layer is a continuous layer at the first corner segment and whereby the first internal layer comprises a first cutout shape at the first corner segment,
• whereby the first cutout shape is elongated along the first corner segment, whereby the first cutout shape terminates more than about 0.5 cm away from the first and second longitudinal fold lines,
• whereby the first cutout shape has a maximum total span, along the first and second flanks and in a plane parallel to the top, of at least about 0.3 mm, and
• whereby the first cutout shape has a length of less than about 90% and of more than about 10% of a height of the first internal layer along the first corner segment.
