Technique and device for measuring fluids including finger valve and filler mechanism

Technique and apparatus for measuring liquids and granular material comprises a combination including a measuring vessel attached adjacent to the top and communicating with the primary container through the modifying pour spout of the latter. The measuring vessel includes an outwardly directed dispensing mouth having a removable closure, and a second upwardly directed opening vertically aligned with the pour spout of the primary vessel. In a preferred embodiment, the modifying pour spout of the primary container serves as a handle for the combination. After the primary container is filled through a tube extended through the second opening of the measuring vessel, this opening is either sealed, or a manually-operable valve is interposed into the opening. The manually-operable valve may alternatively take the form of a flap valve, or a piston valve, either of which operates to open and close communication through the modifying pour spout between the measuring vessel and the primary container. Another alternative feature of the combination is a pinch-valve, interposed into the constriction between the base of the measuring vessel and the primary container, which opens by distorting when compressed between the thumb and finger, releasing excess fluid in the measuring vessel to flow back into the primary container.
