Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a can container that incorporates a cooling or heating device (hereinafter referred to as a heat exchange device) that utilizes the heat absorption or heat radiation effect caused by a chemical reaction when combined with water or other reaction liquid. The chemical reaction of the heat exchange device is promoted to quickly and reliably exchange heat with the contents, and an embodiment thereof will be described with reference to the accompanying drawings.

In order to understand the present invention, the can container shown in FIGS. 1 and 2 equipped with a heat exchange device will be described. The container 1 extends outward from the open end 3 of a bellows-shaped reactant container 1 having a bottom 2. Partition wall 4 integrated with
The outer periphery of the partition wall 4 is fixed to the case 5 in a watertight manner, and the inside of the case 5 is divided into a chamber a and a reaction chamber b communicating with the inside of the main reaction agent container 1, and a beverage is placed in the chamber a. Contents such as water and food are filled and sealed with a can bottom 6. Inside the reaction main agent container 1, there is a cooling agent such as urea, sodium thiosulfate, crystalline sodium chloride, which combines with water and absorbs the surrounding heat. The reaction chamber b is filled with a main reaction agent for heating or a main reaction agent for heating, such as quicklime, which generates heat when combined with water, and a reaction liquid container 9 containing water as a reaction liquid in a plastic film container that is easily torn. It is housed and covered with a removable lid 7.

Immediately before using the can configured as described above, the reaction liquid container in reaction chamber b is broken, the water inside reacts with the main reaction agent, and the absorbed or released heat is exchanged with the contents, so that the contents can be removed. Cool or heat.

However, there is a drawback that it takes a considerable amount of time for the reaction liquid to reach the bottom of the container 1 from the open end 3 of the main reaction agent container 1, and to improve heat exchange with the contents, the main reaction agent container 1 is If it is shaped like a bellows or has an uneven surface that has a large contact area with the contents, mixing of the main reaction agent and the reaction liquid will be poor.

This invention solves the above-mentioned drawbacks, and is characterized by mixing an appropriate amount of a fissile agent in the form of a powdered silica gel crystal, which causes a severe fission effect when mixed with a reaction liquid, into the main reaction material. The mixing amount varies depending on the properties of the main reaction agent, but it is approximately 10% of the main reaction agent. When in use, open the lid 7, break the reaction liquid container 9, and quickly close the lid 7.
administer.

As described above, as the reaction liquid permeates from the open end of the reaction main agent container 1, it is absorbed by the fissile agent mixed into the reaction main agent, rapidly expanding the fissile agent,
Due to the strain during this expansion process, the fissile agent itself causes a severe fission action, and is violently ejected from the reaction main agent container 1 into the reaction chamber b together with the reaction main agent, causing a reaction between the reaction main agent and the reaction liquid in the reaction chamber b. At the same time, the reaction liquid container 9 is agitated to promote the flow of the reaction liquid, the fissile agent mixed in the reaction main agent in the reaction main agent container 1 is activated, and the action of blowing the reaction main agent into the reaction chamber b is repeated. Actively mix the reactant and reaction liquid to promote heat exchange.

Therefore, the entire amount of the main reaction agent is reacted quickly and completely, and the time required for heat exchange with the contents is shortened.

As described above, according to the present invention, the fissile agent mixed in the reaction main agent disturbs the reaction main material and blows it up into the reaction chamber b, so that the reaction mixture with the reaction liquid is quickly and completely, and the can is shaken during the reaction. Since this is not necessary, it is extremely convenient for contents such as beer and carbonated drinks, where vibration of the container is not desirable. Mixing has an effect that can be achieved reliably.
