Abstract
Abstract A filling nozzle assembly includes an elongated fill sleeve (94) for insertion into a container (14). A fill tip (92) is located at an end of the sleeve and is axially slidable between open and closed positions. A spring 122 biases the tip to its closed position. An apparatus (24, 32) is provided to lower the sleeve into the container during which time a shroud (96) contacts the container inhibiting further insertion of the sleeve, but permitting axial movement of the fill tip, thereby opening same. A latch (100) keeps the fill tip open as the sleeve is withdrawn from the container until the latch is tripped by a release mechanism (146).

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
254 words
A filling nozzle assembly for filling a container comprising: a) an elongated fill sleeve having a first end for insertion into the container and for introducing liquid into the container; b) means for introducing liquid into the fill sleeve; c) a fill tip at the first end of the fill sleeve and axially slidable (i) to an open position relative to the sleeve for opening the first end of the sleeve, and (ii) to a closed position relative to the sleeve for closing the first end of the sleeve; d) means biasing the fill tip into the closed position to prevent liquid from flowing out of the fill sleeve; e) means for lowering the fill sleeve and fill tip toward the bottom of the container; f) means for raising the fill sleeve and fill tip out of the container; g) means preventing the sleeve from being lowered to a position proximate to the bottom of the container, the preventing means not interfering with the tip being lowered to a position proximate to the bottom of the container so that the tip can be axially displaced relative to the sleeve to the open position, thereby opening the first end of the sleeve against the force of the biasing means; h) latch means maintaining the tip in the open position as the sleeve and tip are raised from the bottom of the container; and i) means for releasing the latch means as the sleeve is raised to the top of the container by the raising means.
Claim 2
Dependent Claim
254 words
A filling nozzle assembly for filling a container comprising: a) an elongated fill sleeve having a first end for insertion into the container and for introducing liquid into the container; b) means for introducing liquid into the fill sleeve; c) a fill tip at the first end of the fill sleeve and axially slidable (i) to an open position relative to the sleeve for opening the first end of the sleeve, and (ii) to a closed position relative to the sleeve for closing the first end of the sleeve; d) means biasing the fill tip into the closed position to prevent liquid from flowing out of the fill sleeve; e) means for lowering the fill sleeve and fill tip toward the bottom of the container; f) means for raising the fill sleeve and fill tip out of the container; g) means preventing the sleeve from being lowered to a position proximate to the bottom of the container, the preventing means not interfering with the tip being lowered to a position proximate to the bottom of the container so that the tip can be axially displaced relative to the sleeve to the open position, thereby opening the first end of the sleeve against the force of the biasing means; h) latch means maintaining the tip in the open position as the sleeve and tip are raised from the bottom of the container; and i) means for releasing the latch means as the sleeve is raised to the top of the container by the raising means.
Claim 3
Dependent Claim
51 words
A machine for filling a plurality of containers simultaneously with a liquid comprising a rotary filler table for supporting the containers during filling, a series of individual filling nozzle assemblies as defined in claim 1 mounted radially above said table for movement relatively between raised, inactive positions, and lowered filling positions.
Claim 4
Dependent Claim
29 words
The filling nozzle assembly of any one of the preceding claims wherein the lower surface of the fill tip is slanted downwardly toward the axial centerline of the assembly.
Claim 5
Dependent Claim
38 words
The filling nozzle assembly of any one of the preceding claims in which the tip includes a vacuum vent that is operational only when the tip is in a position closing the first end of the fill sleeve.
Claim 6
Dependent Claim
101 words
The assembly of any one of the preceeding claims further including a vacuum shroud mounted on the sleeve and axially displaceable relative thereto with the shroud remaining at the top at the container as the fill tip and fill sleeve are lowered into the container, the shroud including air vent means for venting air from the container as it is filled with liquid, the air vent means being sized so that the volumetric rate at which liquid is introduced into the container is greater than the volumetric rate at which air can be vented from the container through the air vent.
Claim 7
Independent Claim
150 words
A method for filling a container with a liquid comprising: a) lowering a fill sleeve having a fill port adjacent its end into the container without introducing any liquid into the container before the fill port is proximate to the bottom of the container; b) when the fill port is proximate to the bottom of the container,starting the introduction of liquid into the container through the fill ports; c) continuously introducing liquid into the container through the fill port while simultaneously raising the fill sleeve so that the fill port is below the top of the liquid in the container, the liquid being introduced into the container in a controlled volume by a metering piston; and d) stopping the introduction of the liquid into the container when the fill sleeve is raised to a position so that the fill port is almost to the desired liquid level in the container.
Claim 8
Independent Claim
150 words
A method for filling a container with a liquid comprising: a) lowering a fill sleeve having a fill port adjacent its end into the container without introducing any liquid into the container before the fill port is proximate to the bottom of the container; b) when the fill port is proximate to the bottom of the container,starting the introduction of liquid into the container through the fill ports; c) continuously introducing liquid into the container through the fill port while simultaneously raising the fill sleeve so that the fill port is below the top of the liquid in the container, the liquid being introduced into the container in a controlled volume by a metering piston; and d) stopping the introduction of the liquid into the container when the fill sleeve is raised to a position so that the fill port is almost to the desired liquid level in the container.
