DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to those requiring temporary cooling, such as the head and body of a sick person who is in a fever state, fresh food such as fish and meat requiring cold preservation (hereinafter referred to as "cooled"). A heat storage cold pack that can be used to cool the body or to expand, for example, peripheral blood vessels to promote local blood circulation, so that the side to be applied to the object to be cooled can be softly fitted during use, The present invention relates to a heat storage and cooling pack and a heat storage and cooling pack mounting tool, both of which have improved cooling efficiency and heat retention efficiency.

[0002]

Conventionally, cold packs that are commonly used synthetic resin film pack of Te and heat storage cold medium <br/>, C ₁₄ paraffins and C ₁₆ paraffins such as typified by n- paraffinic compounds And n-paraffin derivatives such as high-density polyethylene and cross-linked high-density polyethylene; salt hydrates such as CaCl ₂ .6H ₂ O; and (C ₄ H ₉ ) ₄ NCHO ₂ .32H ₂ O When a clathrate compound represented by, for example, is packaged and sealed and frozen in a freezing room of a home refrigerator, even if the heat storage refrigerant is used, it will be completely frozen at -10 ° C. Conventionally, when a sick person has a fever, or when an athlete wants to cool down after exercising, use it on the head, elbows, shoulders, etc. instead of ice, and when sending fresh food such as fish to a remote place. In order to keep fresh food such as fish in a packaging box cool for a long time, this cold pack is placed and transported together with fresh food.

[0003] On the other hand, in the past, in addition to the coldness of the limbs due to poor blood circulation, neuralgia such as stiffness and low back pain, muscle pain, and poor blood circulation such as chronic arthritis, recently, in addition to impossible posture and continuous Work or deterioration of living environment,
For the health problems caused by poor blood circulation due to stress and the like, physical treatment of warming the local area has been performed as a treatment to suppress these symptoms. In order to achieve this object, warm compresses containing camphor, mint oil (menthol) and the like as active ingredients are known, and cataplasms or plasters containing a warming stimulant are commercially available. .

The interior of the heat storage and cooling pack is divided into sections, each section being liquid at a predetermined temperature or higher, and a portion enclosing a heat storage medium cooled at a temperature lower than that temperature, and a semi-solid or solid state at a predetermined temperature or higher. As a portion enclosing the medium composition having a viscosity close to a liquid or liquid in a temperature range equal to or lower than the temperature, even if the medium composition has a viscosity close to the liquid or liquid at the time of cooling, a bias is generated in the pack. Not to occur. And,
It is another object of the present invention to use a heat insulating material for a part of the cool pack so that the pack can be maintained in a cooled state for a long time.

Further, a medium composition which becomes semi-solid or solid at a temperature equal to or higher than a predetermined temperature of the heat storage cool pack by appropriately combining the heat storage cool pack with a mounting device, and has a liquid state or a viscosity close to a liquid in a temperature range of the temperature or lower.
