Embodiment Construction
[0029]FIG. 1-4 show four preferred embodiments of the present invention having a cooling compartment 10 for items / contents (not shown) requiring storage at temperatures below ambient temperature, and a dry ice module 1 that can be integral with cooling compartment 10 and which is made from or lined with an insulating material 2 that encloses the dry ice 7 primarily to slow down the rate of its sublimation, but which also prevents the outside of the dry ice module 1 from becoming hazardous to touch. Insulating material 2 or materials may comprise a combination of rigid insulating board or lightweight flexible insulating material, but is not limited thereto. Dry ice module 1 also has a lid or flap 6 that can be opened for introduction of a new supply of dry ice 7 when the previously used supply of dry ice 7 becomes spent. Dry ice module 1 can be positioned external to or within cooling compartment 10. Dry ice module 1 is made from any insulating material 2 or combination of materials ...
