Container made of plastics

Abstract

Abstract PURPOSE:To prevent heat accumulation density from lowering and to improve an efficiency of crystalline nucleus formation, by forming a container wall with a plurarity of layers and by incorporating a nucleating agent for a hydrate-base phase-transition material into an inner layer in a container for a hydrate-base phase-transition heat-accumulating agent. CONSTITUTION:A wall of a container for a hydrate-base phase-transition material is formed by a plurality of layers, and a nucleating agent for the hydrate- base phase transition material, for example, strontium chloride hexahydrate for calcium chloride hexahydrate is incorporated into an inner wall. With this constitution, a liquid-phase transition material comes in contact with the nucleating agent to induce crystallization from the container wall and effectively prevent the supercooling, because part of the nucleating agent is fixed in an exposed state. Thus, heat accumulation density is prevented from lowering and an improvement in an efficiency of the nucleating agent formation can be contrived.
