ABSTRACT:
A closure for an opening in the surface of a drum or barrel, especially for a drum or barrel which has been reconditioned by heating so that the original gaskets have been burned out of the opening. The closure includes a cylindrical sleeve disposed in the opening and having a threaded inner surface. The threads of an externally threaded cylindrical cap engage the threads of the sleeve. The cap has an annular generally circular lip about its outer periphery and at its outer end, which lip extends perpendicularly to the sleeve adjacent the outer end of the sleeve so that the outer portion of the lip is parallel to the drum surface. A flexible resilient cylindrical gasket is coaxially mounted external to the sleeve so that the gasket lies between the lip and the drum surface. When the cap is screwed inwards into the sleeve, the lip compresses the gasket against the surface of the drum so that the gasket is squeezed and deforms, and thus so that the gasket forms a closure seal against fluid flow out of the drum.
