PORTABLE STORAGE CONTAINER

A portable insulated storage container comprises an outer layer and an inner liner positioned inside the outer layer. The inner liner defining an internal storage volume inside the portable insulated storage container. Insulation is positioned between the inner liner and the outer layer. A closable opening extends through the outer layer and the inner liner for accessing the internal storage volume from outside the portable insulated storage container. A closure mechanism has a first rigid member hingedly attached to a second rigid member for permitting access to the internal storage volume through the closable opening and for closing the closable opening. The closure mechanism extends around a perimeter of the closable opening. The rigid members each extend around respective portions of the perimeter of the closable opening, pivot in opposite directions, and are in substantially a same plane when the closure mechanism is in the opened position.
