器の提供を目的としたものである。By the way, when food is stored in a container having no bottom hole, there is a problem that the food at the bottom is easily stuffy because the moisture of the food is not absorbed at all. Also, in the case of a container having a bottom hole, the bottom hole is closed by food, and the air permeability is impaired. In particular, a container having a bottom hole can be effectively used for freezing, thawing, heating, and re-frozen frozen food using the bottom hole. The effect of can not be fully exhibited. Furthermore, in a container provided with a lid, there is also an inconvenience that the stored food adheres to the front surface of the lid. The present invention has been made in view of the above circumstances, and aims to provide a food container in which ventilation and moisture elimination are sufficiently performed to improve food quality and cooking efficiency. It is.
