Abstract: An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. A head of the drain closure assembly is fastened to a top end of a stem, wherein a bottom end of the stem is insertable in a drain shoe; and a gasket is fastened around an outer cylinder of the stem below the head. The gasket comprises an upper outer portion and a lower outer portion that each meet at a line that defines a hinge at which the gasket is able to bend, wherein the lower outer portion features a sloped surface from a bottom edge of a rim of the gasket to the line at a top of the lower outer portion, wherein the upper outer portion has a right circular cylinder shape.

Abstract: An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a head of the drain closure assembly that is fastened to a top end of a stem, wherein the bottom end of the stem is insertable in a drain shoe. The assembly further includes a gasket fastened around an outer cylinder of the stem below the head. Accordingly, the gasket comprises a series of concentric annular platforms such that a force applied to a top surface of the gasket causes an upper concentric annular platform having a smaller outer diameter to be compressed before the lower concentric annular platform having a larger outer diameter is compressed, thereby creating a seal between the head of the drain closure assembly and the drain shoe.

Abstract: An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a domed cap at a top portion of the drain closure assembly and a flange that is positioned below the domed cap. The assembly further includes a stem that extends from below the flange to a bottom portion of the drain closure assembly and a gasket seal that is positioned around the stem at a bottom of the drain closure assembly. The gasket seal has a frusto-conical shape, wherein a top portion of the gasket seal has a wider diameter than a bottom portion of the gasket seal, and the gasket seal has a central circular opening that fits closely around the stem.
