Abstract
A wedge shaped container formed from a folded web of flexible material. The container comprises a base (1), a rear wall (2) connected to the base, and a pair of upstanding side walls decreasing in height from the rear wall to the opposite end of the base. Each side wall is formed of two side wall panels (4, 6) connected at an edge of the base and connected by a hinge joint. From a fold-flat configuration, folding of the rear wall (2) away from the base (1) causes the side wall panels (4, 6) to be folded inwardly into the erected configuration. The container may have an integral lid (8). The invention also extends to a method of making a blank using a sequence of cuts to create unsupported file regions.

A wedge shaped container formed from a folded web of flexible material, the container comprising:
- a base,
- a rear wall connected at a first edge of the base via a first fold line,
- and a pair of upstanding side walls, one on each side of the base, each side wall decreasing in height from the rear wall to the opposite end of the base such that in an erected configuration the base, rear wall and side walls form a wedge shape;
- each side wall being formed of a first side wall panel extending along and connected at an edge of the base via a second fold line transverse to the first fold line;
- and
- a second side wall panel extending along and connected at an edge of the rear wall via a third fold line transverse to the first fold line;
- wherein the side wall panels of a respective side wall are connected together by a hinge joint, so that, from a fold-flat configuration, in which the rear wall overlies the base, folding of the rear wall about the first fold line away from the base causes the respective side wall panels to be folded inwardly about the second and third fold lines into the erected configuration in which the first and second side wall panels form the upstanding side walls to form the wedge shaped container.
