As shown, a conventional food container includes a container body (2) and a normal food container (1) having a lid (3) which can be opened and closed in a pressurized manner on top thereof, wherein the main body (2) Is composed of an inner and outer body (2a, 2b) made of a separate synthetic resin, the inner and outer body (2a, 2b) is characterized in that it has a plurality of locking jaws (2 ') that can be molded to each other do. At this time, the upper jaw and the upper outer surface of the main body 2 to form the fitting jaw (2a, 2b, 2c), the corresponding fitting is formed in the inner surface of the lid 3, the fitting groove omitted in the drawing, the lid 3 The plurality of reinforcing recesses 3b and the reinforcement protrusions 3a are formed.

Conventional food storage container is formed by a plurality of locking jaw is formed in the inner and outer body so that the lid is consolidated to the main body is sealed, the interior of the storage container is sealed, to achieve the purpose of improving the sealing force and preventing the outflow of food will be.

However, the conventional food storage container seems to prevent leakage of food inside the storage container by improving the sealing force at room temperature, but the conventional food storage container, usually made of plastic, is particularly exposed to high temperature external environment such as summer or microwave oven. When the temperature of the sealed space is increased by the heat transferred from the outside. This leads to expansion of the storage space, and the container body and the lid are inflated by the elasticity of the stretchable synthetic resin.

Therefore, eventually, a gap is generated between the expanded container body and the lid, and eventually the food stored therein is leaked out through the gap.

In addition, it is impossible to reuse the storage container itself due to the rupture of the container body or the lid which does not resist the expansion, resulting in an economically inefficient problem and an unfriendly environment due to the generation of waste materials due to rupture.

The present invention has been made to solve the above problems, an object of the present invention is to form a protrusion on the container in which food is stored to prevent the outflow of food and to prevent the container from being ruptured by the expansion of the storage space. It is to provide a food container.
