17. A device for dispensing a constant portion of liquid from a container having a mouth, the dispensing device comprising:
-
a pour spout adapted for coupling to the mouth of the container, said pour spout including an end wall sloping inwardly towards a center of said pour spout; an inverted cup including an interior cavity, a check valve disposed in said interior cavity, and a discharge port and an open mouth communicating with said interior cavity; and a dispensing tube coupling said pour spout to said discharge port, wherein the container comprises a side wall coupled to a bottom, said bottom including a well portion comprising a base and a shoulder, and said open mouth being adapted for sealing against said shoulder such that said cup, when disposed in the container, defines a measuring reservoir including an inlet port positioned diametrically opposite to said end wall, said check valve comprising; a tubular member having an internal passageway, and including a fluid outlet coupled to said discharge port and a fluid inlet opening into said interior cavity, a length of said tubular member adjacent said fluid outlet having a substantially uniform cross-section; and a float means slidably disposed within said internal passageway and having a density which is less than a density of the liquid, a cross-section which substantially corresponds to said cross-section of said length of tubular member, and a face shaped for sealing against said fluid outlet.
