The present invention relates to a packing clamped onto a food container enabling the inside of the container to change into a vacuum state when the temperature drops inside the container as heated and cooked food stored therein becomes cold so that the food stored therein does not spoil and can be preserved for a long time, and particularly, to a vacuum packing for a food container which rapidly restores a contracted container to the original shape thereof when the vacuum state is released, does not become deformed even if used for a long time, and does not fall off when the lid is opened. |
