    Patent number: 4375578
    Abstract: A sealing liner of flexible material such as Teflon has a downwardly tapering side wall which is positioned over a header. A case is positioned over the liner, and the top of the case is moved into engagement with the top of the liner to capture the tapered side wall of the liner between the side walls of the header and the case to provide a tight cold flow seal so that small particles working loose from the case cannot reach the header.
