초록 ▼

A seal and closure member of elastomeric material adapted to be cast in situ and comprising a cylindrical body portion and an integral frusto-conical skirt therewithin. A radially outwardly extending flange is embedded in adjacent concrete. The skirt has a knock-out web at its smaller diameter end portion and the seal and closure member may thus be employed selectively as closure members for apertures in distribution boxes and the like and as seals for pipes in communication with the box interiors.

대표청구항 ▼

A combination aperture closure and low pressure seal for an exterior surface of a pipe adapted to be mounted in a cylindrical aperture and to receive an end portion of a pipe in a monolithically cast fluid distribution box or the like of the cementitious material; said seal being composed of molded elastomeric material and comprising an annular body portion having generally cylindrical inner and outer surfaces, the former defining a central cylindrical pipe receiving opening which extends axially through the body portion and the latter engagable with the aperture wall, an integral annular flange on said body portion extending generally radially outwardly and adapted to be embedded in the cast cementious material about the aperture during casting of said box whereby to secure the seal in position in the aperture, and a hollow generally frusto-conical sealing skirt formed integrally at its larger diameter end portion with the seal body portion and projecting inwardly at an angle between radial and axial planes, the smaller diameter end portion of said sealing skirt being slightly smaller in diameter than the pipe to be received and being disposed radially inwardly from said inner cylindrical body surface and free to expand diametrically, and frusto-conical sealing skirt being adapted to receive and guide an end portion of a pipe introduced at its said larger diameter end portion and urged toward and axially through its said free smaller diameter end portion whereby to slightly diametrically expand said free end portion and thus to establish firm frictional engagement and effective sealing thereof with the exterior peripheral surface of the pipe, said seal further including a knock-out web which takes a substantially circular disc configuration and which extends radially across the smaller diameter free end portion of the frusto-conical sealing skirt, said web being molded integrally with the skirt and having an integrally molded weakened narrow annular portion adjacent the skirt free end portion to facilitate web knock-out so that said seal can serve a dual purpose selectively as a closure for an associated aperture and a seal for a pipe entered in the aperture.
