Abstract
Abstract A head cooling implement capable of covering the human skull like a cap for medical treatment. It comprises a main body consisting of a cooling piece for covering the top of the head and a plurality of cooling pieces radially arranged around the first-mentioned cooling piece for covering the front, sides and back of the head, each cooling piece being in the form of a sealed bag containing a coolant; a stretchable belt applied to the chin so as to bring the head top cooling piece of the main body into close contact with the top of the head; another stretchable belt adapted to bring the other cooling pieces of the main body into close contact with the skull at suitable places therearound; and a heat insulating cap to be put over the main body.
