  • Patent number: 4351165
    Abstract: A cooler having a removable coolant receptacle secured between and dividing a pair of insulated containers attached together by a hinge. The coolant receptacle closes the openings of the two containers and divides the cooler into separate compartments. The coolant receptacle extends partially into both compartments and thus provides lateral support to the cooler when their openings are closed against each other. A carrying strap is attached at its ends to one of the containers and is also releasably attachable to the other container to hold the containers together in a closed position. Another strap securing the coolant receptacle to the other container is secured to the other container by the releasable attachment means for the carrying strap. Each container has an outer shell and an inner insulation shell held within the outer shell by an inwardly extending lip at the periphery of the outer shell opening.
