Embodiment Construction

[0020] A plunger 10 manufactured according to the first embodiment of the invention is shown in Figures 1-4. The plunger 10 can be seen in its closed position in FIG. 1 and in its open position in FIG. 2 , and comprises a shaft 15 having an end connected to a head 16 . The head 16 and shaft 15 are used in a conventional manner to force liquid through a sewer pipe in order to remove said obstruction by forcing it through the pipe under the pressure generated by the deformation of the head. Thus, the head 16 is arranged to create a seal around the sewer to be unclogged and the shaft 15 is advanced towards the head 16 so as to fold the head and create a pressure surge in the sewer to be unclogged. Therefore, the head 16 must be made of a material, such as rubber, which is flexible and which automatically returns to its original shape when the advancing force on the shaft 15 is removed or interrupted. On the other hand, the shaft must be made of a rigid material such as, for exam...

Abstract

A dripless plunger (10) includes a head (16) connected to a shaft (15) and a cover (14) movable under user control of an actuator (12) on the shaft (15) from a closed position in which the cover (14) overlies the head (16) to prevent drippage from the head (16) after use of the plunger (10) to clear a clogged drain, and an open position in which the cover (14) is moved to a position remote from the head (16) to permit the head (16) to be placed sealingly about the drain and deformed for forcing water through the drain to unclog the same.

Description

technical field [0001] The present invention relates to a plumbing set for clearing obstructions in toilet and sewer pipes and the like, said plumbing set including an integral cover to prevent dripping of liquid from the plunger after use. Background technique [0002] Conventional manually operated terminals include a resiliently deformable cap or head secured to a handle. During use, the cap is placed over a blocked drain to form a seal around said blocked drain, and the handle is then depressed while the cap retracts and applies pressure to the obstruction in the drain. The cap portion of the plunger is designed in many different configurations for various applications and to increase applied pressure. For example, U.S. Patent No. 1,193,476 (Block) discloses a plunger having a basic hat-shaped design with a reinforced brim; U.S. Patent No. 5,974,596 (Strzok) discloses a plunger device that The plunger has an inner lumen and an outer lumen for applying pressure to the o...
