Abstract
Bottle mounted liquid metering apparatus including a helical fastener band self-adapting to a thread pitch. In alternative embodiments, collars rotatively supported relative to a pour tube and a plug portion control the size of a vent aperture and/or a fill window within the interior of the bottle along the pour tube and thereby the volume dispensed; a bottle vent integrally extends from the body of a threaded cap or a plug in radial relation thereto; and electronically timed annunciator means sequentially, uniformly meter a dispensed volume.

Liquid metering apparatus for a liquid containing bottle comprising:
- a. nozzle means having a bore in communication with the bottle interior for dispensing liquid through said bore;
- and
- b. means for forming a liquid tight seal between said nozzle means and said bottle wherein said seal means includes a cap having sidewalls and an annular top wall and further includes a discontinuous flat band having first and second lateral edges of differing lengths extending between a bottom and a top edge and positioned in concentric, frusto-conical relation to the interior of said sidewalls such that the shorter of the first and second lateral edges and said top edge are rotatively engageable with threads projecting from said bottle and such that said band resiliently flexes at a point of rotation to compressively seal against said bottle.
Liquid metering apparatus for a liquid containing bottle comprising:
- a. nozzle means including a tubular member having a bore in communication with the bottle interior for dispensing liquid through said bore, wherein said tubular member includes an exposed fill aperture in communication with the bottle interior and opening through a sidewall of said tubular member to said bore;
- b. means for forming a liquid tight seal between said nozzle means and said bottle wherein said seal means includes a cap having sidewall and an annular top wall and further includes a discontinuous flat band having first and second lateral edges of differing lengths extending between a bottom and a top edge and positioned in concentric, frusto-conical relation to the interior of said sidewalls such that the shorter of the first and second lateral edges and said top edge are rotatively engageable with threads projecting from said bottle and such that said band resiliently flexes at a point of rotation to compressively seal against said bottle;
- and
- c. means for selectively varying the exposure of said fill aperture and thereby defining a repetitively deliverable liquid volume.

Liquid metering apparatus for a liquid containing bottle comprising:
- a. nozzle means includes a bore in communication with the bottle interior for dispensing liquid through said bore;
- b. battery means;
- c. timing means for producing a periodic control signal of a predetermined duration;
- d. switch means for coupling said battery means to said timing means upon filling said bore;
- e. annunciator means responsive to said periodic control signal for indicating the dispensing of uniformly identical volumes of liquid with the occurrence of each control signal, and whereby a user can dispense measured volumes of liquid without interrupting the liquid delivered to said bore;
- and
- f. means for forming a liquid that seal between the nozzle means and said bottle including a cap having sidewalls and an annular top wall and further including a discontinuous flat band having first and second lateral edges of differing lengths extending between a bottom and a top edge and positioned in concentric, frusto-conical relation to the interior of said sidewalls such that the shorter of the first and second lateral edges and said top edge are rotatively engageable with threads projecting from said bottle and such that said band resiliently flexes at a point of rotation to compressively seal against said bottle

Liquid metering apparatus for a liquid containing bottle comprising:
- a. nozzle means including a tubular member having a bore in communication with the bottle interior for dispensing liquid through said bore, wherein said tubular member includes a first vent aperture opening through a sidewall to said bore from the bottle interior, a second vent aperture in communication with the atmosphere and bottle interior and further including at least one fill aperture opening through a sidewall of said tubular member in communication with said bore and the bottle interior and positioned forward of said first vent aperture and wherethrough the liquid enters the bore;
- b. first means including a first collar concentrically mounted in relation to the tubular member and rotationally operative along a radial axis for selectively varying the exposure of said fill aperture;
- c. second means including a second collar concentrically mounted in relation to the tubular member and rotationally operable along a radial axis for selectively varying the exposure of said first vent aperture and whereby the first and second means define a repetitively deliverable liquid volume;
- and
- d. means for forming a liquid tight seal between said nozzle means and said bottle.
