でほぼｔｉｔである。Further, the combination and mixing ratio of these two powders can be appropriately selected depending on the desired cooling temperature and cooling duration. Among these, a preferred combination is an example in which ammonium nitrate and urea powder is used as the dissolved endothermic substance powder, and sodium sulfate decahydrate powder is used as the metal hydrate powder. In general, a preferable mixing ratio of the dissolved endothermic substance and the powder of the metal hydrate is approximately tit in terms of weight ratio.

納すむこともできる。Before use, separate both powders with a water-impermeable thin film so that they do not mix. This thin film is water-impermeable, like a plastic film, to prevent crystallization water from penetrating, and can be broken before use. For example, this thin film is adhered to the inner peripheral surface of the container so as to divide it into two parts, and the powder of the dissolved endothermic substance and the metal are placed on both sides of the container, respectively. The hydrated salt powders may be stored separately, or one powder may be stored in a pouch made of a thin film, and this pouch may be stored together with the other powder in a container.

A thick, water-impermeable container that can hold the water without leaking and that does not tear during handling is sufficient.A flexible bag-like container that allows the container to easily fit into the head when cooling the head, etc. The preferred material for the container and thin film is a plastic film such as polypropylene, polyethylene, or soft vinyl.

。[Function J] In the portable coolant of the present invention, the dissolved endothermic substance powder and the metal hydrated salt powder are separated by a water-impermeable thin film in a container such as a bag so that they do not mix before use. The powders are stored separately, and when used, the thin film is manually broken from the outside of the container and both powders are mixed in the container. When both powders are mixed and come into contact, crystals form from the metal hydrate salt powder. As water gradually liberates and dissolves the dissolved endothermic substance powder,
The surroundings of the container are cooled by absorption of heat during this melting.

いし水溶液の容積が同一であれば１本冷却剤は一１７℃
程度の最低温度が得られ、温度が０℃になる迄はるかに
長い時間冷却作用を維持することができる。In the present invention, since the wood for dissolving the dissolved endothermic substance is supplied from the water of crystallization contained in the hydrated metal salt, the release of the water of crystallization from the hydrated salt progresses only little by little, and therefore the dissolution into the free crystallized water The dissolution of the endothermic substance and the endothermic reaction at that time can be sustained for a long time. When compared to conventional ice cooling or commercially available simple coolants, one coolant cools at -17°C if the volume of water or aqueous solution remaining at the end is the same.
A very low temperature can be obtained and the cooling effect can be maintained for a much longer time until the temperature reaches 0°C.

と金属含水塩の粉末として結晶粒径の大きなものを使用
するほど°、冷却作用の持続時間が長くなる。Furthermore, if at least one of the dissolved endothermic substance and the metal hydrate powder is mixed with a powder of a substance that thickens water such as sodium alginate or poval, or a powder of sodium acrylate called a polymer absorber, It is possible to maintain the cooling effect for a longer period of time.Furthermore, the larger the crystal grain size is used as the dissolved endothermic substance and metal hydrate powder, the longer the cooling effect lasts.
更に又、溶解吸熱物質及び金属含水塩とも粉末を使用す
るので、両者の接触面積が大きくなり、結晶水を利用す
るにもかかわらずその遊離が比較的容易であり１両粉末
の混合から冷却効果が発揮されるまでの時間も極めてみ
じかい。Furthermore, since powders are used for both the dissolved endothermic substance and the metal hydrate, the contact area between the two is large, and although crystal water is used, their release is relatively easy, and the cooling effect can be obtained from mixing the two powders. The time it takes for this to manifest is also extremely short.
