Description

  The present invention relates to a cold insulator used by mixing a freeze-type gel enclosed in a small bag with an antifreeze-type gel stored in a storage bag.

Conventionally, as for the cooler used to obtain a refreshing sensation at the time of fever due to illness, bruise, or summer, the one in which the cooler is stored in the synthetic resin storage bag is generally known. Yes. For example, at home, the cold insulator is placed in a freezer for a required time, and is used after the internal cold insulator is frozen. Therefore, the cold insulator itself is in a state of being hardened and hardened at the start of use, and it must be used with a solid feel until the internal cold insulator melts and becomes liquid.
In order to solve such problems, various cold insulators aimed at improving fit to the body during use have been proposed as shown below.

  Japanese Utility Model Laid-Open No. 6-31715 (Patent Document 1) aims to provide an antifreeze-containing ice pillow that maintains the same state as a conventional ice pillow containing water and ice.

The purpose of this invention is to provide a heat-cooling device that can be used, and it is characterized by putting a cryogen packed in a small bag into another large bag filled with antifreeze and closing the bag and wrapping the bag with a cover for different purposes. “Heat cooling device” has been proposed.

  Further, in Japanese Patent Application Laid-Open No. 2001-61882 (Patent Document 3), the cooling capacity of the regenerator material is used mainly as a cooling pillow that is effectively used for cooling the head at a rate as high as possible. For the purpose of providing a cold insulation bag, a layer made of a cold storage material on the upper side and a layer made of a large number of synthetic resin foam granules on the lower side in the main body bag are mutually connected to the cold storage material and the synthetic resin foam granules. A “cold insulation bag” characterized by being arranged in a manner that does not mix is proposed.

  In addition, JP 2004-97491 A (Patent Document 4) aims to provide a comfortable ice pillow that can quickly cool an ice pillow in a freezer, and that a moderate coldness is transmitted to the head during use. A sheet-like or plate-like heat insulating member and a cold insulation bag which is placed on the heat insulation member and is frozen and divided and enclosed in a bag, and stacked on the cold insulation bag, and is antifreeze in the bag. An ice pillow comprising a non-freezing bag in which a mold composition is housed, an outer bag for integrally storing these heat insulating sheets, a cold insulation bag, and an anti-freezing bag in a pillow shape. An “ice pillow” characterized in that a cooling release agent is blended and a plurality of holes are formed in the heat insulating member has been proposed.
