Abstract: A cold storage material and a cold storage pack are provided where a single cooling medium (cold insulation pack) containing a cold storage material having a plurality of melting points can keep an object at a low temperature that is suited to a situation. The cold storage material changes phase at a prescribed temperature and contains: water; a base compound containing a quaternary ammonium salt that forms a semi-clathrate hydrate; and a supercooling inhibitor that suppresses supercooling, wherein the cold storage material has one or more melting points depending on a temperature range in which the cold storage material has been frozen. These features allow the user to set the melting point of the cold storage material as he/she wants, by properly changing the freezing temperature for intended usage

Abstract: There are provided a cooler container, cold tray, and red wine server in which it is possible to adjust the temperature of an outer surface on the buffer layer side of the container to a temperature that differs from the melting point of a freezing material. The cooler container adjusts temperature of an object to be cooled that includes a beverage or food product, the cooler container having at least a region with a hollow structure, the cooler container including: a thermal storage layer in the region, the thermal storage layer containing a freezing material that changes phase at a specific temperature; and at least one buffer layer in the region, the at least one buffer layer being separated from the thermal storage layer in the region and containing an antifreeze material that is a fluid at a phase transition temperature of the freezing material. The provision of the at least one intervening buffer layer enables the temperature of the outer surface on the buffer layer side of the container to differ from the melting point of the freezing material.
