PURPOSE:To prevent deterioration of exothermic drugs and to promote the reduction of manufacturing cost by removing an inner cylinder, by a method wherein a water storage room and an exothermic drugs storage room are provided so as to adjoin each other in a vessel, their opening ports are sealed by a common bottom sheet, and their ports are opened by an attached pull tape. CONSTITUTION:When a tag (8a) of a pull tape 8 is pulled, a bottom cover 7 is forcibly peeled from each end face of opening ports 5 and 6, which are respectively for a water storage room 3 and an exothermic drugs storage room 4, since the other end of the pull tape 8 is connected to a joining margin of the bottom cover 7. Water in the water storage room 3 and exothermic drugs (quicklime) in the exothermic drugs storage room 4, are then dropped on the bottom of the vessel 1, and a reaction is started. On the other hand, the water dropped on the bottom of the vessel 1 is gradually penetrated in the exothermic drugs storage room 4, and the reaction is further activated. The contents in a packing can 10 are thus warmed by hot vapour produced in this reaction. In addition, when a special control water (the fact recognized by everybody) is used for the water in the water storage room 3 of an exothermic body 2, it is possible to freely control temperature rise of the exothermic drugs of quicklime and the like. |
