  • Patent number: 10221551
    Abstract: A pressure plunger which consists of a hollow lower tube inserted into a clogged toilet or drain causing no significant displacement of fluid. After the lower tube's compressible end is fixedly attached to a fluid channel, the actuator cylinder may be inserted into the lower tube to create pressure downward and upward to remove blockage. Unlike other designs this plunger consists of two separate sections, each integrally formed, which function together without assembly or disassembly. Vents near the top of the lower tube allow in air to release vacuum pressure when pulling near the top of the lower tube prohibiting fluid being pulled to the top of the lower tube. The lack of assembly and disassembly is also significantly different regarding cleaning and sanitizing. The upper actuator tube can be pulled out and cleaned on the outside and the lower tube can be easily cleaned from either end.
