BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sealing structure of a cover for a cooking container, and more particularly, to a sealing structure of a cover for sealing the inside of the cooking cavity of the cooking container.

Generally, the cooking vessel expands the air inside the cooking chamber when the food is heated, and at this time, the air can discharge the air through the gap that pushes out the door, and when the heating of the food is finished, The inside air can be shrunk to a low pressure state.

Such a cooking vessel has a function of storing food in a low-pressure state and preventing the food from being damaged while maintaining a low-pressure state.

Such a general cooking vessel can seal the inside of the cooking vessel through a sealing structure that directly connects the packing, which is the sealing means, to the rim of the cover made of metal.

However, such a structure has been problematic in that the sealing means is deformed or detached from the lid to lower the sealing force.

Accordingly, there has been developed a cooking vessel having a structure capable of prolonging the storage of food by preventing the rapid decay of food by storing the food in a low-pressure state by improving the sealing force of the cooking vessel for storing food in a low pressure state .
