Cooling device for cooling parts in the proximity thereof

Abstract

A cooling device for cooling parts in the proximity thereof consisting of a single pouch or a plurality of continuous pouches, wherein each pouch has at least one face thereof being made of water-permeable material and has sealed therein a hygroscopically swelling material. Due to such construction, the sealed material of the cooling device in an unemployed state, i.e., before being chilled in a freezer or freezing compartment, is not hygroscopically swelled and is not voluminous so that it can be decreased in weight by reducing the quantity of the sealed material which can improve the transportation efficiency, resulting in lowered transportation costs. Furthermore, the device can be easily and securely attached to any body part or object such as the shoulder of a man or a beer bottle.
