Abstract: A soft-sided insulated container that has a rigid closure. The rigid closure has a first closure interface that is a passive friction fit in which one part wipes another. The rigid closure has a second closure interface that is an active closure in which a mechanical device, such as a latch or clamp, is used positively to energize a closure between different parts of the closure. The container has a vent. The latch operates to close the vent. The soft-sided insulated container has a soft-sided external casing, and a rigid internal liner that includes a mating rigid lid. There is a releasable securement that holds the liner in engagement with the casing, but that can be released to permit the casing to be extracted from the liner. The releasable securement is a one-way passively engageable securement.

Abstract: A soft sided insulated container assembly includes a first portion having an insulated, soft sided external wall structure, and an internal, substantially rigid molded plastic receptacle mounted therein. It has a cover structure that includes a reinforcement member for engaging a land region of the molded receptacle, thereby tending to yield an interface tending to have a sealing relationship. The container may also include a thermal storage element, and the container may have an accommodation for receiving the thermal storage element.
