Cooling pack

摘要

A cooling pack comprises at least one coolant carrier (10) for keeping coolant held thereon and a container (11) adapted to enclose the coolant carrier (10). The coolant carrier (10) consists of liquid absorbent substrate (12) and liquid absorbent polymer particles (13). The container (11) has at least a pair of flat layers opposed to each other which are adapted to introduce liquid into the container (11). The cooling pack can provide beneficial features such as to avoid exudation of liquid absorbent polymer particles (13), to introduce liquid into the container (11) in a short period of time, and to obtain non-sticking of the container (11) refrigerated condition.
