Abstract: A thermally insulated holder for accommodating a single beverage-containing can of standard size is comprised of two identical mating halves, each half comprised of an integral monolithic jacket fabricated of a closed cell foam of a resilient polymer, and a refrigerant container positioned at the bottom of the jacket. The refrigerant container is adapted to confine a refrigerant liquid. The two halves are adapted to be brought together in sealing abutment about the beverage-containing can. Grooves within the jacket conduct the cooling effect of the refrigerant to the beverage-containing can.
