Plunger apparatus with controllable ventilation

摘要

A plunger assembly having a plunger portion and an elongated handle with a central bore. The plunger portion has a bottom opening sized for fluid communication with a drain opening. The top end of the plunger portion has a threaded opening sized to receive the threaded end of the elongated handle, and allowing for fluid communication with the central bore. A check valve assembly rests on an annular seat formed inside the bottom of the elongated handle proximate the opening formed in the top end of the plunger portion. The check valve serves to allow airflow into the top end of the plunger portion while preventing airflow out of the top end of the plunger portion to prevent undesired backflow. Further regulation of the air flow into the plunger portion is achieved by providing a cap, at the top of the elongated handle for selectively allowing airflow into and through the central bore. The cap, in cooperation with a rubber gasket, allows for variable control of the amount of air which can enter the central bore and therefore the plunger portion. An adapter element may be used to allow connection of the handle to a conventionally sized threaded plunger portion. A portable carrying case provides a sanitary enclosure which allows for movement of the plunger between rooms with contaminating other rooms with potentially hazardous biological waste and debris.
