Title:
自己加熱/自己冷却容器
Document Type and Number:
Japanese Patent JP4174046
Kind Code:
B2
Abstract:
A self-heating or self-cooling container, which uses a chemical reaction to effect heating or cooling. The reagents for the chemical reaction are stored separately in two sealed compartments ( 5, 6 ) having a common dividing wall ( 7 ), which can move within the compartments to expand the volume of one compartment at the expense of the other compartment. This arrangement allows efficient use of space within the reaction module of the can, which is particularly important where large amounts of reagent are required to obtain the necessary heating or cooling effect and where the products of the chemical reaction occupy a significantly increased volume compared to the initial reagent in the compartment.
