Claims24
A blank for a container comprising
- a base including at least a first edge, a second edge spaced apart from the first edge, a third edge, and a fourth edge spaced apart from the third edge,
- a first side wall coupled to the base along the first edge,
- a second side wall coupled to the base along the second edge,
- a front wall coupled to the base along the third edge, and
- a back wall coupled to the base along the fourth edge,
- wherein the blank is made from a sheet of insulative cellular non-aromatic polymeric material,
- wherein the insulative cellular non-aromatic polymeric material includes a cell forming agent and a base resin having a high melt strength polypropylene,
- wherein each of the first side wall, the second side wall, the front wall, and the back wall all have a first thickness and the blank further comprises a flap at an outboard edge of the first side wall, the flap being separated from the first side wall by an area having a second thickness, and the second thickness being less than the first thickness,
- wherein each area having the second thickness is plastically deformed, and
- wherein the second wall thickness is plastically deformed without fracturing the insulative cellular non-aromatic polymeric material so that a predetermined insulative characteristic is maintained in the blank.
