Abstract
A collapsible insulated container has a base wall and a peripheral wall with an open end defining an enclosure. The peripheral wall has at least two layers and is divided into elongate pockets between the layers, with foldable crease lines between adjacent pockets. Each pocket contains a flexible-walled, insulating gel pack which substantially fills the pocket. The crease lines may be defined by stitching securing the outer and inner layers of the container together. The gel packs may be surrounded by matting, foam or mesh material which is sewn into the lines of stitching, or may have integral peripheral rims sewn into the lines of stitching. The container is foldable between an erect, open condition and a storage condition in which it is folded along the crease lines into a substantially flattened package.
