An insulated shipping container includes a formed body of foamed polymer material. This formed body defines a chamber, an opening from the chamber outwardly to ambient, a transition surface surrounding this opening, and an exterior surface. Preferably, the chamber and exterior surface are both cylindrical prismatic shapes of like configuration so that a uniformly thick wall of insulative foamed polymer material is provided between the chamber and ambient. A single sheet of plastic is integrally bonded to the foamed polymer body such that it faces all of the chamber, the transition surface, and a substantial portion of the exterior surface of the container. In one embodiment of the container the remainder of the exterior surface of the container is faced with a separate sheet of plastic, and the two pieces of plastic cooperate to define an escape slit at which excess foamed polymer material escapes during formation of the container in a fixture. In another embodiment of the container this un-foamed plastic sheet faces all exterior surfaces of the foamed polymer material, including those which bound the chamber.

[ I claim:] [1.]1. A plastic bag article of manufacture with a closed end portion having a first hoop dimension, an opposite open end, and a transition section of second hoop dimension greater than said first hoop dimension, said plastic bag article being turned back on itself with the closed and open ends in juxtaposition so that said plastic bag article provides an annular space between spaced apart inner and outer wall portions of said transition section, said plastic bag article being for use in making an insulated container having a body of foamed polymer material substantially contained between said spaced apart inner and outer wall portions of said plastic bag article, said body of foamed polymer material defining a chamber therein having an end surface defining an interior perimeter dimension and an opening outwardly from said chamber, said opening being surrounded by a transition surface defining an exterior perimeter dimension, said plastic bag article comprising:said end portion defining said respective first hoop dimension which is substantially equal to but greater than said interior perimeter dimension;said transition section having a wall portion extending from said end portion to a transverse line at which said plastic bag article defines said second hoop dimension which is substantially equal to but greater than said exterior perimeter dimension and which is sufficient to allow said plastic bag article when turned back on itself to extend across said transition surface of said body of foamed polymer material.
