Abstract: A plunger device for unblocking a clogged drain or pipe, comprises a valve housing interposed between a handle and a suction cup; a valve seat having an opening for communicating the cup with the housing; a fluid outlet formed in the housing to provide a fluid path to the outside of the device; a valve ball positioned in the housing to close said opening of the valve seat and said fluid outlet when said ball is positioned on the seat, a bolt moveable in said housing to abut said ball for locking the ball between the bolt and said seat, thereby causing fluid under pressure to flow in one direction-into the clogged drain, the bolt being movable away from said ball to unlock the ball and open said fluid outlet, said ball moving freely inside the valve housing when said ball is unlocked, thereby enabling fluid to flow in the opposite direction only—out from the clogged drain; and switch means associated with the bolt and lock and unlock the valve ball when clearing the clogged drain.

Abstract: A no spill container including a bottle having a threaded neck for attaching to a threaded cap. The cap includes a conical stopper and a flared skirt extending inward on the bottle. The inward end or hem of the skirt provides a gripping surface away from the neck of the bottle for opening and closing the cap. The neck includes an opening to receive the stopper when the cap is closed. An aperture is formed in the cap. When the cap is open, fluid in the container flows into the neck opening and is discharged from the aperture. When the cap is closed the stopper extends inside the neck opening and the outer end of the neck closes the aperture in the cap, to thereby prevent fluid flow out from the container.
