Abstract
Abstract An insulated shipping container comprising a modular container stack and an exterior protective shell. The modular container stack is constructed from two basic units, a receptacle unit having a bottom portion and a spacer ring unit having an open bottom. The basic units are nested together to form a modular container stack having the desired number of compartments. A cap is placed on top of the units to complete the stack. In one embodiment, a cleat is fixedly held between the exterior shell and the modular container stack to provide structural rigidity to the insulated shipping container.
