Stretchable cooling sheet

Abstract

A stretchable cooling sheet (11) provided with a hydrous gel layer (13) comprising a water-soluble polymer and a large amount of water contained in the polymer, which comprises the hydrous gel layer (13), the first sheet (14) which is made of a stretchable fiber and placed on the underside of the gel layer (13) in such a way as to cover the whole of the underside, a pressure-sensitive adhesive layer (17) containing powdered aluminum and a release paper (19) which are placed on the underside of the first sheet (14) successively in such a way as to cover the whole of the underside, and the second sheet (16) which is at least unidirectionally stretchable and is placed on the face of the hydrous gel layer (13) in such a way as to cover the whole of the face. In using, the release paper (19) is peeled off and the resulting sheet is applied directly to an affected part with the pressure-sensitive adhesive layer (17) faced to the affected part, whereby the cooling sheet (11) can adhere stably to an affected part and the water contained in the hydrous gel layer (13) can evaporate through the first and second sheets (14, 16) to make a cooling effect on the affected part.

Description

technical field [0001] The present invention relates to a cooling expandable body, and more particularly, to a cooling expandable body that can easily apply ice packs as a method of body care after exercise, and can be directly attached to the skin for ice packs. Background technique [0002] As a technique for absorbing heat by direct contact with the skin, a scented gel sheet in which a gel material containing moisture is applied to cloth has been proposed (see Japanese Patent Application Laid-Open No. 11-246397). In addition, there is also proposed a body wearing device for cooling that utilizes heat absorption and compression (refer to Japanese Patent Application Laid-Open No. 2001-87080). Furthermore, a cooling bag in which a cooling material is processed into a bag shape during heat generation has been proposed, and it is used after exercising or in ordinary households (refer to Japanese Patent No. 3574496). [0003] Assuming the following situation, that is, in order...

Problems solved by technology

In this case, since the contents are ice or a cooling material, there is a possibility that the affected part may be cooled excessively, resulting in frostbite, and an accident may occur instead.

[0005] In addition, if the paste body or cooling pack is directly contacted with the skin and stuck on the skin surface, the affected area will be cooled rapidly, causing the body to shrink instantly.
