Modular waxless seal

摘要

A waxless modular seal prevents leaks in the connection between the base of a toilet and the drain pipe. The waxless modular seal comprises a rubber portion and a resiliently compressible toroid-shaped foam ring, both of which are, in combination, designed to replace a traditional wax seal. The waxless modular seal captures the foam ring between an upper sealing ring and a lower sealing ring. Each sealing ring and the foam ring comprises a protrusion and at least one vertically disposed aperture, the apertures being sized sufficiently so as to allow a fastener to pass through the apertures. The foam ring may comprise a plurality of foam rings.

1. A waxless modular seal for sealing a connection between a bottom of a toilet and a waste drain, the seal comprising:
a generally cylindrical rubber portion having a compressed state and an uncompressed state, the generally cylindrical rubber portion comprising: a flat upper sealing ring; a flat lower sealing ring, the lower sealing ring being flat when the generally cylindrical rubber portion is in the uncompressed state; a central section disposed between the flat upper sealing ring and the flat lower sealing ring, the central section configured to collapse inwardly of the sealing rings when the generally cylindrical rubber portion is in the compressed state; and a ring horn tapered inwardly from the central section; and a rectangular toroid-shaped foam ring interposed between the flat upper sealing ring and the flat lower sealing ring, the rectangular toroid-shaped foam ring having a flat top and a flat bottom.
