Abstract: Provided is a cooling tool that keeps a cooling object cold by utilizing the latent heat of a cold storage material and can visualize the physical condition of the cooling tool, i.e., can indicate whether the use condition of the cooling tool is appropriate. For example, when leakage of the cold storage material occurs, the cooling tool indicates the leakage of the cold storage material and shows whether the temperature is appropriate for keeping the cooling object cold. The cooling tool keeps the cooling object cold by utilizing the latent heat of a freezable material and includes: the freezable material that undergoes phase change at a specific temperature; a cold storage layer including a first container portion that contains the freezable material; and a condition indicator that shows the physical condition of the freezable material.

Abstract: A cooling pack is provided that can both maintain the human body at a suitable, low temperature and ensure a sufficient usage time. The present invention, in one aspect thereof, is directed to a cooling pack that cools a human body. The cold storage layer includes: a freezing medium having a phase transition temperature specified in a range of temperature suitable to maintain the human body at low temperature; and a cold-storage-layer-packaging member containing the freezing medium therein. The buffer layer includes: an antifreeze medium flexible at the phase transition temperature of the freezing medium; and a buffer-layer-packaging member made of a flexible material and containing the antifreeze medium therein. The buffer layer has a prescribed thermal conductivity, thermal diffusivity, thermal effusivity, and heat transmission coefficient. The buffer layer is brought into contact with human skin to transfer heat between the human body and the cold storage layer.

Abstract: A flame-retardant thermal storage medium is provided that has an effective temperature range lower than the effective temperature range of congruent-melting-point-concentration TBAB without reducing the latent heat of the congruent-melting-point-concentration TBAB. The thermal storage medium changes phase at a prescribed temperature and contains: water; TBAB at such a concentration with respect to the water as to give a congruent melting point of a semi-clathrate hydrate; and KCl dissolved in the water. The thermal storage medium contains at least 0.90 moles of KCl per 1 mole of TBAB
