ABSTRACT:
A pliable, thermally insulative container is provided for maintaining the temperature of the contents inside the container which facilitates the use of ice as a cooling medium. The pliable, thermally insulative container comprises a substantially cylindrical body formed of an exterior shell, an interior liner and flexible insulative material. The body has a top end and a bottom end. The exterior shell and interior liner are attached at the top end creating an interior insulative space between the exterior shell and the interior liner and a storage space lined by the interior liner. In accordance with one aspect of the invention, a waterproof base is attached to the exterior shell at the bottom end of the body sealing the interior insulative space. The flexible, insulative material is disposed within the interior insulative space. The container preferably includes a band at the top end with a quick-release coupling attached thereto for closing the opening at the top end of the container.
