ABSTRACT:
A bottle cap having a valve which provides a water tight seal to prevent spillage when a water bottle is inverted for installation onto a water dispenser, but which can be opened after the water bottle is installed by generating a hydraulic shock wave within the bottle to open the valve. A first embodiment has a triple valve seal with mechanical interference between the valve pieces to create an initially water tight seal. A second embodiment employs a dual valve structure. A third embodiment employs a single valve structure. In the first three embodiments, the valves are pivotally attached to the valve body by flexible living hinges. A fourth embodiment has a single linearly sliding valve. Three methods are presented for generating the hydraulic shock wave to open the valve. In the first method, the water bottle is positioned just above the water dispenser and lowered rapidly. In the second method, the bottle is placed on the dispenser and tipped so that one shoulder of the bottle is just above the top opening of the dispenser, then the bottle is allowed to settle back into place. These two methods create an inertial shock wave when the bottle comes to rest. In the third method, the bottle is placed on the dispenser with the seal intact, and the user strikes the top or the sides of the water bottle to create the hydraulic shock wave.
