Abstract
A cover assembly for closing off the opening in a panel so as to establish a sealed interface around the opening includes a cover member with a four corners arrangement of clearance holes for attachment of the cover to the panel which also includes a matching pattern of clearance holes. The cover assembly includes a gasket member which is constructed with a carrier and a cooperating edge seal. The carrier includes a substantially planar surface which faces the cover member and extending outwardly from this facing surface are two series of pin-like projections. The cover member is cooperatively arranged with two substantially straight and elongated channels which are constructed and arranged to receive the outwardly extending projections. The two channels act as abutment surfaces for the projections so as to restrict outward or lateral movement of the gasket relative to the cover and panel. At any point when there is internal pressure of sufficient magnitude to deflect the gasket, the protrusions are moved into abutment against the sidewalls of the receiving channels, thereby preventing any further movement of the gasket and preventing blowout.
