A thermal energy storage container is disclosed having a generally rectangular configuration. The container is made of a synthetic resinous material and is rotomolded to form a high-strength and seamless container capable of use over extended periods of time and over many freeze-thaw cycles of a thermal energy storage material contained within the container.

A seamless container containing a hydrated phase change material wherein said phase change material undergoes expansion during its phase change from a frozen to a molten state and undergoes contraction during its phase change from a molten to a frozen state, said container being generally rectangular in shape and comprising opposed front and rear walls, opposed side walls, and opposed top and bottom walls, one of said walls having an opening for introduction of the phase change material into the container, and a closure member for closing the opening and for hermetically sealing the phase change material within the container, a plurality of spaced indentations extending from either of the front or rear walls and merging into the opposite wall for maintaining the front and rear walls in a substantially fixed parallel position with respect to each other, said container being constructed of a synthetic resinous material and formed by rotational molding during which the synthetic resinous material is concentrated in the corners of the container such that the corners haven an internal rounded contour with an increased thickness and are capable to withstand repeated flexture of the container wall during expansion and contraction cycles of the phase change material.
