ABSTRACT:
A heat insulated container for cold storage of articles, the container having a device therewithin for containing solid CO.sub.2. The device has a heat insulated body with an internal cavity open to a base thereof, the base resting on a lower heat conductive plate within the container such that the device can be positioned as desired in the container with a lower cavity opening facing the heat conductive plate. Solid CO.sub.2 is positioned within the cavity, resting on a member mounted therewithin and movable in the cavity to vary the spacing of the solid CO.sub.2 from the heat conductive plate, thus to vary the cooling effect of the solid CO.sub.2.
