The present invention relates to a dent prevention structure of a cooking container and, more specifically, relates to a dent prevention structure of a cooling container which enables steam generated from content inside the container to be discharged to the outside of the container through a discharge hole, and external air to be supplied to an inner space through the discharge hole; thereby preventing the container from being dented inwardly. The dent prevention structure of the cooking container includes: an open-top structure to receive food; a flange surface along an edge of a top end; a sealing protrusion protruding at a specific height along the flange surface to be bonded to a cover film for sealing; an auxiliary sealing protrusion formed on the flange surface protruding inside the sealing protrusion at the same height with the sealing protrusion, and forming a specific-sized discharge space with both ends connected to the sealing protrusion; a discharge hole formed on the flange surface where the discharge space is formed to discharge steam; a pointed portion formed on an inner part of the auxiliary sealing protrusion such that the cover film can easily be separated when the internal pressure in the container increases; and protruding guides protruding on both sides to form the discharge hole on a center such that external air can be supplied to the inner flange surface separated from the pointed portion of the auxiliary sealing protrusion through the discharge hole. |
