Siphoning device for use in basting, measuring or immiscible liquid separation

The method of liquid separation and transfer using a device having an hollow body member, said body member having a outlet region, a two-way liquid valve positioned within said outlet region and having a stem member extending through said outlet region to the exterior of said hollow body member, said liquid valve restricting liquid flow out of said hollow body member and permitting the flow of liquid into said hollow body member, air pump means, said air pump means being in fluid tight engagement with said hollow body member and interacting with said liquid valve to expel air from said hollow body member and to draw fluid into said hollow body member, comprising the steps of:

• pumping air out of said device through said air pump means by constricting said air pump means,
• inserting said outlet region into a hot liquid such that the outlet of said outlet region is below the surface of said liquid,
• siphoning liquid into said device, by releasing said air pump means,
• withdrawing said outlet region from said liquid, the two-way liquid valve restricting flow of liquid out of said device,
• moving said device to a desired location,
• activating said liquid valve by applying pressure on the portion of said stem member which extends exteriorly of said hollow body member, to allow said liquid to flow from said body member to said desire location, and
• axially dispensing along said stem member, at least a portion of said liquid at said desired location.

A siphoning device for use in the basting of foods with a hot liquid and liquid-liquid separation of hot liquids, comprising:

• a hollow body member, said body member having a first end, a second end and an elongated body region between said first end and said second end,
• said first end having an interior tapered surface and a fluid flow opening, said fluid flow opening having a maximum radial dimension, and said tapered surface tapering inwardly toward said fluid flow opening,
• air pump means, said air pump means interacting with said second end of said body member to expel air from said hollow body member and to draw liquid into said hollow body member, and
• a two-way liquid valve, said two-way liquid valve being positioned at said first end, proximate said fluid flow opening, and having an elongated stem member and a seal means, said seal means being fixed to said stem member,
• said stem member having a first end and a second end, and being affixed to said seal means at said first end for travel with said seal means, the length of said stem member being substantially greater than said first open tip end fluid flow opening radial dimension, said
• stem member extending through said fluid flow opening, said seal means being movable from a first position to a second position, and engaging said interior tapered surface of said outlet region, proximate said first open tip when in said first position, thereby precluding fluid flow out of said hollow body member, and disengaging said interior tapered surface of said outlet region when in said second position, thereby permitting flow into and out of said hollow body member, wherein in said second position, said stem member second extends beyond said fluid flow opening by a distance which is substantially greater than said fluid flow opening radial dimension,
• whereby when said seal means is in said first position, said stem portion extends through and substantially beyond said open tip end, and when said stem portion second end is moved toward said open tip end of said outlet region, said seal member is moved away from said interior tapered surface of said outlet region a distance which is substantially greater than said fluid flow opening radial dimension, providing a progressively increasing opening and an axial flow of liquid out of said fluid flow opening and along said stem portion.

A siphoning device for use in the basting of foods with a hot liquid and liquid-liquid separation of hot liquids, comprising:

• a hollow body member,
• said body member having an outlet region,
• said outlet region having an interior surface and a first open tip end with a fluid flow opening,
• said fluid flow opening having a radial dimension, and
• an elongated body region, said elongated body region having a second open end,
• a one-way air valve, said air valve restricting air flow into said hollow body member and permitting air flow out of said hollow body member,
• a two-way liquid valve, said two-way liquid valve being positioned within said outlet region, proximate said first open tip end for opening and closing said open tip end, and
• air pump means, said air pump means 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 an elongated stem member and a seal means, said seal means being movably positioned within said outlet region,
• said seal means being movable from a first position to a second position and engaging said interior surface of said outlet region, proximate said first open tip when in said first position, thereby precluding fluid flow out of said open tip end of said hollow body member, and disengaging said interior surface of said outlet region when in said second position, thereby permitting flow into and out of said open tip end of said hollow body member, said stem member having a first end and a second end, and being affixed to said seal means at said first end for travel with said seal means, said stem member extending substantially beyond said open tip end when said seal means is in said first position, and when said stem portion second end is moved toward said open tip end of said outlet region, said seal member is moved away from said interior surface of said outlet region thereby opening said open tip end;
• and wherein pressure on said stem portion in the direction of said seal means moves said seal means 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 first open tip end fluid flow opening and along said stem member.

The method of liquid separation and transfer using a device having an hollow body member, said body member having a outlet region, a two-way liquid valve positioned within said outlet region, said liquid valve restricting liquid flow out of said hollow body member and permitting the flow of liquid into said hollow body member, air pump means, said air pump means interacting with said hollow body member to expel air from said hollow body member, a one-way air valve, said air valve preventing air flow into said hollow member and permitting air flow out of said hollow body member, comprising the steps of:

• pumping air out of said device through said air pump means by constricting said air pump means,
• inserting said outlet region into a liquid such that the outlet of said outlet region is below the surface of said liquid,
• siphoning liquid into said device, by releasing said air pump means, air being prevented from entering said hollow body member by said air valve,
• withdrawing said outlet region from said liquid, the two-way liquid valve restricting flow of liquid out of said device,
• moving said device to a desired location,
• activating said liquid valve to allow said liquid to flow from said body member to said desired location, thus dispensing at least a portion of said liquid at said desired location,
• repeatedly activating said air pump while said outlet of said outlet region is below the surface of said liquid, said liquid valve preventing the flow of liquid from said device while permitting fluid flow into said device, thereby repeatedly drawing liquid into said device.
