Patent number: 6123336Abstract: A sealing device (20) includes a layer of sealant (22) for sealing an internal surface (30) of a hollow member (34). The internal surface is nonparallel to the open end of the hollow member, and has an aperture pattern (44) for receiving at least one substrate (40) extending from a support surface across the hollow member. The layer of sealant is disposed adjacent the internal surface and supported by a backing (24) having an aperture pattern corresponding to the aperture pattern of the internal surface. The backing is spaced from the support surface and is movably supported inside the hollow member. The layer of sealant is adhered to the front surface of the backing to form a self-supporting article that can be easily positioned into the hollow member. One or more substrates can be inserted through the support surface across the hollow member, through the apertures in the backing and the layer of sealant, and through the apertures on the internal surface.Type: GrantFiled: May 27, 1997Date of Patent: September 26, 2000Inventor: Janusz B.
