Abstract

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.

DETAILED DESCRIPTION OF THE INVENTION 1. Field of the Invention This invention relates to a heating element provided in a container to heat the contents, and a food/beverage heating container using this heating element.

Conventionally, coffee and the like are often sold after being heated to an appropriate temperature in vending machines to make them suitable for drinking.

However, in outdoor settings such as mountain climbing and camping sites, it has been impossible to instantly heat canned beverages such as coffee and other beverages for consumption.

As an invention that overcomes these drawbacks, a metal inner layer such as A1 is added to the inside of a can that was conventionally made of a heat-resistant material (for example, a composite can made of laminated aluminum foil, paper, synthetic resin film, etc.). BACKGROUND ART Food and drink warming containers in which a cylinder is inserted are known. The opening edge of this inner cylinder is wrapped around the lower edge of the can body,
A heat generating material and an ice bag are both housed within this inner cylinder. When in use, a needle is inserted from below to pierce the water bladder, causing the exothermic material to react with water, and the heat of the reaction warms the contents.

■I'm trying to do this. However, with conventional food and drink heating containers like this,
The heating material (quicklime) stored directly in the inner cylinder was not completely isolated from the outside air, so it had the disadvantage of being deteriorated by moisture in the air. In addition, conventional food/beverage heating containers require an inner cylinder, have a large number of parts, and have the drawbacks of high manufacturing costs due to the need for a seaming process for the inner cylinder.

This invention has been made in view of these conventional problems, and provides a heating element that prevents the deterioration of the heat generating material (quicklime), and also provides a heating element for food and drinks that does not require an inner cylinder and is inexpensive to manufacture. The purpose is to provide a container.
