Built-in latent heat storage agent sealed with a product or high-temperature heat-resistant resin film. The built-in latent heat storage agent utilizes the phenomenon of melting and solidification, which stores heat (heat storage) when changing from solid to liquid by heating and releases heat (latent heat) when changing from liquid to solid by cooling. It keeps warmth.

Conventionally, there is a method of boiling the whole tableware in hot water, heating it in a constant temperature chamber, or using a heat storage agent separately kept warm before cooking the ingredients and putting them on the tableware.

As a method of heating using a heat storage agent, there is a latent heat storage agent containing sodium acetate as a main component, and there is a method of heating a packed heat storage agent in a microwave oven.

When boiling tableware in hot water, it is necessary to wipe off the adhering water, and with the method of heating in a constant temperature chamber, it is difficult to set the appropriate heat retention conditions depending on the frequency of use.

The heat retention temperature of the above-mentioned latent heat storage agent containing sodium acetate as a main component is about 50 ° C to 60 ° C, and the latent heat reaction gradually deteriorates with the lapse of use time, and there is a drawback that a long-term heat storage effect cannot be obtained. there were.

The latent heat storage agent, which is mainly composed of sodium acetate, has a filling amount of 100%, and it has been reported that if it is heated too much in a microwave oven, the bag will break in the microwave oven, which poses a safety problem. there were.

The latent heat storage agent containing the main component of sodium acetate takes a time of 4 minutes or more to heat, and there is a limit to the number of times of repeated use, which causes an economic problem.
