<p>The present invention relates to a cooking pot cover including a packing capable of adsorption by vacuum and sealing under constant pressure. Particularly, the present invention provides a structure which has the packing, which covers the edge of the cover and is detachably joined, and a wing packing, which induces vacuum and is not stuck on a packing main body when folded with the packing main body, prevents impurities from being stuck thereon, and can be manufactured in an easy manner. According to the present invention, a plunger is formed on a packing main body of the packing, which covers the edge of the cover and joined with the cover so that the packing can be pressed by a locking means. A protrusion is formed between the packing main body and the wing packing so that the wing packing can be prevented from being stuck, can be cleaned in an easy manner, and can be manufactured in an easy manner while impurities are not stuck thereon. Moreover, even when the cover is placed on a container having an upper edge only, the cover is prevented from escaping as a rib is formed to protrude in a vertical direction of the packing main body and the rib can support the cover.</p> |
