Abstract
A portable soft sided insulated container has an impermeable liner that provides a liquid holding barrier. The liner is folded from a single monolithic plastic sheet to reduce or eliminate the need for heat welded seams. The liner seats within the container and has a releasable attachment around its lip for mating with the rim of the container. The container has an insulated lid so that the entire assembly may be closed. The liner can be removed for cleaning, or replacement if punctured. When not in use the entire assembly can be folded into a collapsed position for storage. The container has two storage chambers that share a common insulated dividing wall.
