<p>The present invention comprises a container having a top (3) and bottom (2) or two-part form, the outer shell of the container is made of a shock-resistant thermoplastic material having a maximum possible deterrent to heat transfer. The interior of the container (28) on each part thereof contains an envelope containing the freezable gel which is sealed and made of a stiff plastic material which generally holds its form even when the gel therein is unfrozen. The envelope (28) on each side is spaced from the interior wall of the outer casings in both instances to provide an air barrier (34) within which moisture within the barrier has been removed to the maximum extent possible. The gel within the frozen envelopes can be placed in a frozen state by various methods. The two portions of the container may be joined together either by a hinged element (5) along one side of the corresponding locking mechanism (6) on the opposite side or by a plurality of locking mechanisms on at least two opposite sides of the container.</p> |
