Abstract
Provided is a seal for sealing a sink or other overflow drain in fluid communication with a sink drain system. The seal is used in conjunction with a pressure-based drain-opening device. The seal is configured as a releasable adhesive tape that includes water-resistant, flexible, conformable sheet material having pressure-sensitive adhesive layer adhered to one surface of the sheet material. Optionally, a protective layer may overlie the adhesive layer. The properties and characteristic of the overflow drain seal components are selected such that the seal, when engaged, has sufficient adhesive force to overcome an aperture force impinging the seal from pressure generated upon activation of the pressure-based drain-opening device
Claims19
A seal for sealing an overflow drain in fluid communication with a fixture drain of a fixture, said seal used in conjunction with a pressure-based drain-opening device, said seal comprising:
- a releasable adhesive tape;
- wherein, before activation of said pressure-based drain-opening device, a first portion of said releasable adhesive tape overlies an overflow drain aperture of said overflow drain and a second portion of said releasable adhesive tape releasably engages a fixture surface area adjacent and circumscribing said overflow drain aperture;
- and
- wherein, after activation of said pressure-base drain-opening device, said second portion of said releasable adhesive tape is released from engagement with said fixture surface area and said first portion of said releasable adhesive tape is removed from overlying said overflow drain aperture.
A pre-packaged drain-opening kit for use in removing a fixture drain blockage in a fixture drain in fluid communication with a fixture having an overflow drain in fluid communication with said fixture drain, said kit comprising:
- a pressure-based drain-opening device;
- an overflow drain seal;
- drain-opening instructions in the use and disposal of said pressure-based drain-opening device;
- seal instructions in the use, removal, and disposal of said overflow drain seal;
- and
- optionally, promotional materials.
