| 摘要 |
The present invention includes an overflow stopper apparatus for reversably blocking the cut-outs in the overflow opening cover, thereby allowing a bathtub to be filled beyond the level of the overflow opening cover. The overflow stopper is formed from a laminar sheet of resilient material, such as closed-pore foam rubber. For additional strength, the overflow stopper may have a facing of stretchable cloth made of a water-impervious synthetic material, such as nylon or polyester, which is unaffected by mildew. The overflow stopper may be stamped or cut from a larger sheet of the resilient material, or it may be molded. The overflow stopper includes a laminar body having a circular aperture which has a diameter less than that of a typical overflow opening cover plate. The overflow stopper is stretched to fit around the periphery of the overflow opening cover plate. Preferred embodiments of the invention include tabs or corners which facilitate the stopper's installation on and removal from the overflow opening cover plate.
