Document Type and Number:
Japanese Patent JPH0359353
Kind Code:
B2
Abstract:
A container for self-heating or self-cooling drinks or foodstuffs housed in the container has a diaphragm and a breaker capable of completely shattering the diaphragm with ease for delivering a liquid reactant to an exothermal or endothermal solid reactant. The container is partitioned into three chambers. One chamber contains drinks and foodstuffs, one contains exothermal or endothermal solid reactants, and one contains a liquid reactant. The diaphragm is made of thin prestressed glass partition between the reactant chamber containing the exothermal or endothermal solid reactant and the chamber containing the liquid reactant. Actuation of the breaker forms a large hole by shattering the prestressed glass diaphragm. The liquid reactant passes through the hole and contacts the exothermal or endothermal reactant, and the ensuing exothermal or endothermal reaction releases or absorbs energy to rapidly heat or cool the drinks or solid foodstuffs. Alternatively, a plastic diaphragm having a scoreline provided at the outer periphery thereof may be used.
