Abstract:
A siphoning device, comprising:an elongated hollow body member, said body member having an interior surface and a first open tip end with a fluid flow opening, said fluid flow opening having a cross-sectional dimension, and a second open end, a two-way liquid valve, said two-way liquid valve being positioned within said first open tip end, and an air pump member, said air pump member interacting with said second end of said body region to expel air from said hollow body member and to draw liquid into said hollow body member, said two-way liquid valve having a seal member, said seal member being movably positioned within said open tip end, between an closed position with said seal member engaging the interior surface of said body member proximate said first open tip to preclude fluid flow out of said hollow body member first open tip end, and an open position with said seal member disengaging said interior surface of said outlet region to permit flow into or out of said hollow body member, the improvements comprising: a stem shroud, said stem shroud having a proximal end affixed to said first open tip end and an open distal end; an elongated notch, said elongated notch within said stem shroud having an open end proximate said open distal end and a closed end proximate said proximal end, an angled stem member, said angled stem member having an interior member and an engagement member, said interior member being affixed to said seal member to extend into said stem shroud and said engagement member angled to extend through said elongated notch; whereby when said seal member is in said closed position, said engagement member extends through said notch at said open end and pressure on said engagement member in the direction of said seal member moves said seal member out of contact with said interior wall, thereby placing said liquid valve in an open position and permitting liquid to be discharged axially from said hollow body member, through said stem shroud.
