PROBLEM TO BE SOLVED: To form, on a container lid, a plurality of concentric ring ribs protruding inwardly in a container for high temperature food for sealing, with the lid, a bottomed non-lid plastic container body filled with high temperature food immediately after heating treatment or high temperature sterilization treatment or the like. SOLUTION: After high temperature food 4 is sealed in a container, lateral sides can be prevented from being dented even if the food 4 is cooled resulting in reduction of an internal pressure of the container. Further, water drops generated in the container as the food 4 cools can be prevented from coming into contact with the food 4, while it is possible to prevent the food in the container from losing a puffy feeling as a result of the food being pressed by a container body 2 or a container lid 3. |
