Abstract
The present cover is used for permanent sealing of an oval-shaped processing hole () in aluminum sheet metal () by means of an adhesive joint. The cover consists of a circular cover plate () of aluminum with a concentric cover edge () and a ring-shaped strip () of hot-melt adhesive applied within the cover edge (). The interior region of the cover plate () is connected to a spring plate () aligned plane-parallel with the cover plate at a spacing of the thickness of the aluminum sheet metal (). The outer edge () of the spring plate () has a contour that corresponds to the shape of the oval processing hole () and includes quarter-circular spring tongues () which are brought to a tight fit by spring force against the back side of the aluminum sheet metal () by a quarter turn of the cover plate to produce the necessary pressure on the adhesive strip ().
