There are equipments for the thermal containers structures such as those known from the document U.S. Pat. No. 4,196,817, granted to Moser D. Wescott, dated Apr. 8, 1980, consisting of a layered pliable couplings bag for creating a thermal environment wherein a container is housed, wherein ice may be provided there between, in such a way that when pushing the bag, the liquid contained therein may be expelled through a straw provided therein.
Other examples of these kind of pliable thermal containers are known from the documents: U.S. Pat. No. 4,537,313 granted to Eleanor Workman, dated Aug. 27, 1985; document U.S. Pat. No. 2,464,069 of R. G. Benson on Mar. 8, 1949.
