    • A drain stopper assembly for selectively opening and closing a drain located within a basin, tub oo sink. A lifting frame assembly is situated within the drain body supporting a stopper. The lifting frame is provided with fust and second annular legions selectively coupled to a piston caused to extend within and withdrawn from the drain body. In a first orientation, the piston extends within a fust annular region allowing the stopper and lifting frame to be removable from the drain body while in a second orientation, the piston extends within a second annular region which prevents the stopper and lifting arm from being removed from the drain body.
    • 排水挡块组件,用于选择性地打开和关闭位于盆,盆内的排水槽。 提升框架组件位于排水体内,支撑止动件。 提升框架设置有选择性地联接到活塞的固定和第二环形小腿,以使其在排水体内延伸并从排水体排出。 在第一方向上,活塞在一个直立的环形区域内延伸,允许止动器和提升框架在第二方向上从排水体移除,活塞在第二环形区域内延伸,防止止动器和提升臂被移除 从排水体。

    • A disposable plug for installation in a cylindrical water line (10, 40) to temporarily block the water line (10, 40) to the passage of water therethrough. The disposable plug includes a cylindrically shaped tablet (26) having a diameter substantially equal to the diameter of the water line (10, 40) so that when installed within the water line (10, 40), water is prevented from passing the disposable plug. The tablet (26) is characterized as being partially dissolvable when contacted with water. A water impermeable membrane (24) surrounds at least a portion of the tablet (26) to selectively prevent water from contacting the tablet as long as the disposable plug acts to temporarily block the water line (10, 40). The water impermeable membrane (24) can be selectively disrupted allowing water to contact the tablet (26) to selectively remove the disposable plug when no longer needed.
    • 一次性插头用于安装在圆柱形水管线(10,40)中以临时阻塞水管线(10,40)到水通过。 一次性插头包括具有基本上等于水管线(10,40)的直径的直径的圆柱形片剂(26),使得当安装在水管线(10,40)内时防止水通过一次性插头 。 片剂(26)的特征在于当与水接触时可部分溶解。 只要一次性塞子暂时阻塞水管线(10,40),不透水膜(24)围绕至少一部分药片(26)以选择性地防止水接触药片。 当不再需要时,不透水膜(24)可被选择性地破坏,使水接触片剂(26)以选择性地移除一次性插塞。
