Abstract
Abstract A device for dispensing a measured quantity of first liquid into a body of a second liquid as the second liguid falls and rises. A container for the first liquid has a dispensing nozzle which includes a small orifice. The nozzle is at the lower most point of the container which is otherwise closed. A U-shaped passage extends from the orifice to an opening within the container adjacent the lowest point thereof. The opposite side of the orifice communicates with an open-bottomed chamber. As the second body of liquid rises air entrapped in the open-bottom chamber is forced through the orifice and U-shaped passage and into the container. When the second body of liquid subsequently drops a controlled quantity of the first liquid is drawn out of the container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
Apparatus for dispensing a quantity of a first liquid into a second liquid, comprising: a container for the first liquid having an opening at its lowermost point; a tubular member extending vertically downwardly from the opening; a nozzle member received within the opening of the container and comprising the upper end of the tubular member, the nozzle member having a small diameter orifice extending therethrough; means for supporting the container and the tubular member whereby the lower end of the tubular member is at a point between a first, upper level and a second, lower level of the second liquid; and a tube within the container extending from the orifice of the nozzle member to a point closely adjacent the upper surface of the nozzle member and defining a passage through which the first liquid must pass before dispensing into the second liquid.
Claim 2
Dependent Claim
143 words
Apparatus for dispensing a quantity of a first liquid into a second liquid, comprising: a container for the first liquid having an opening at its lowermost point; a tubular member extending vertically downwardly from the opening; a nozzle member received within the opening of the container and comprising the upper end of the tubular member, the nozzle member having a small diameter orifice extending therethrough; means for supporting the container and the tubular member whereby the lower end of the tubular member is at a point between a first, upper level and a second, lower level of the second liquid; and a tube within the container extending from the orifice of the nozzle member to a point closely adjacent the upper surface of the nozzle member and defining a passage through which the first liquid must pass before dispensing into the second liquid.
Claim 3
Dependent Claim
28 words
Apparatus according to claim 1 wherein the nozzle member has a well extending downwardly from the top surface of the nozzle member, the tube extending into the well.
Claim 4
Dependent Claim
73 words
Apparatus according to claim 1 wherein the nozzle has an upper portion and wherein the tube is defined by a first bore extending upwardly from the orifice and within the upper portion, a second bore extending substantially parallel to the first bore within the upper portion and having its lower end in communication with the interior of the container, and a cross bore connecting the upper ends of the first and second bores.
Claim 5
Dependent Claim
26 words
Apparatus according to claim 1 wherein the nozzle member, tubular member, and the tube comprise a single operative unit received within the opening of the container.
