Conventionally, in cooking, a food container inside a lid-equipped container is heat-treated from the outside using a lid-equipped container, and is appropriately processed while being heated to provide a heat-treated food suitable for a desired dish. I've been However, in a general container with a lid, when the temperature inside the container reaches 100 degrees Celsius, the moisture expands from a liquid state to a gas state and pushes up the lid and diffuses to the outside. Therefore, in order to increase the pressure in the lidded container, do not separate the lid and the container, use the lidded container as a pressure container, and use a high pressure inside the container to soften fish bones, Even in the case of boiled beans, which takes a relatively long time, it has been possible to shorten the cooking time of beans and save the heating cost and cooking time. However, after heat treatment of the food material in the lidded container, when time passes and it cools, the pressure in the lidded container drops, and the result is that the lid of the lidded container closely adheres to the container body, It happened that they could not be separated easily. At that time, it has been practiced to reheat and remove the lid from the container body. Therefore, various methods have been devised and implemented in order to remove the lid closely attached to the container body from the container body without performing such troublesome work.

One of them relates to a pressure reducing valve structure for a hermetically sealed container according to Japanese Utility Model Publication No. 61-26207, which discloses a device capable of automatically eliminating a negative pressure state in the hermetically sealed container. The technical content thereof is that a sealed container such as a lunch box having a container body and a lid body that openably seals the opening of the container body is provided with an air hole in the lid body and a valve body that opens and closes the air hole. If the inside of the container body is in a negative pressure state due to the temperature decrease, the valve body is opened to eliminate the negative pressure state inside the container body, which allows the lid body to be easily removed from the container body. It's something I got to get. Further, the other one relates to a pressure adjusting device for a microwave oven container according to Japanese Patent Laid-Open No. 2-180217, and a pressure adjusting device for a microwave oven container capable of adjusting a plurality of pressures when performing dielectric heating in a microwave oven or the like.
