AIRTIGHT CONTAINER LID FOR MICROWAVE OVEN, CAPABLE OF AUTO-VENTING

摘要

The problem to be solved by the present invention is to provide an airtight container lid for a microwave oven, wherein a vapor automatic discharge means capable of being manually assembled is added to the lid, thereby enabling cooking after a sealed container closed with the lid is put into a microwave oven. The purpose of the present invention is to allow even medium- and small-sized enterprises to manufacture an airtight container lid for a microwave oven without a burden of equipment by enabling a manually assembling process to be carried out conveniently, the process comprising: inserting an opening/closing member into the inner circumference of a coupling protrusion; fixing the same by means of a fixing member; and inserting the shaft on a finishing member into a shaft-receiving groove.
