Reargued April 27, 1931
Decided May 18, 1931
283 U.S. 420
Patent No. 1,595,426, for a refrigerating transportation package, consisting of an outer, insulating container, with the food substance to be refrigerated (e.g., ice cream) so packed therein as to surround a quantity of solid carbon dioxide in its separate insulating container, and thus to act, with the evolved gaseous dioxide, as a protection for the solid dioxide against exterior heat, the gas also serving to displace air from the food and refrigerate it, held void for want of novelty and invention.
Rehearing of the cause reported ante, p. 283 U. S. 27, limited to the validity of the patent.
