Abstract
Abstract A valved filling head for filling a container with a viscous flowable product includes means for introducing a controlled blast of fluid through the head toward the fill opening or spout of the container at the end of the fill cycle. The fluid stream is directed against accumulated viscous material in the fill opening, in order to push the viscous material down into the container away from the spout and to prevent splattering of the material onto the container and over filling apparatus when the head and spout are separated and the opening is capped.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
A method for filling a container with a viscous material, comprising the steps of bringing the neck of a container into communication with a viscous material outlet, delivering viscous material through said outlet into the container until the level of material reaches the neck of the container and the viscous material extends between said outlet and the container, stopping delivery of viscous material through said outlet, then, with the neck of the container still in communication with the outlet, directing a stream of cleansing fluid under pressure through said outlet and into the neck of the container for discharging all of the viscous material in said outlet and between said outlet and the container into the container, and then removing the container from said outlet, whereupon the viscous material will not cone up in the container neck and said outlet will remain clean.
Claim 2
Independent Claim
143 words
A method for filling a container with a viscous material, comprising the steps of bringing the neck of a container into communication with a viscous material outlet, delivering viscous material through said outlet into the container until the level of material reaches the neck of the container and the viscous material extends between said outlet and the container, stopping delivery of viscous material through said outlet, then, with the neck of the container still in communication with the outlet, directing a stream of cleansing fluid under pressure through said outlet and into the neck of the container for discharging all of the viscous material in said outlet and between said outlet and the container into the container, and then removing the container from said outlet, whereupon the viscous material will not cone up in the container neck and said outlet will remain clean.
Claim 3
Independent Claim
167 words
A device for filling containers with a viscous material, comprising a body having a viscous material inlet, a viscous material outlet connected to said inlet and adapted for reception of the neck of a container for supplying viscous material to the container, a valve member movably mounted in said body for movement into and out of closing engagement within said outlet for selectively establishing and disestablishing communication between said material inlet and said material outlet, a fluid passageway through said valve member having an outlet directed into said material outlet, and means operative upon movement of said valve member into closing engagement within said material outlet for supplying a momentary or premeasured blast of pressurized fluid through said passageway and said material outlet and into the neck of the container for discharging all of the viscous material from said material outlet into said container and for preventing coning of the viscous material in the neck of the container upon removal of the neck from said material outlet.
Claim 4
Independent Claim
167 words
A device for filling containers with a viscous material, comprising a body having a viscous material inlet, a viscous material outlet connected to said inlet and adapted for reception of the neck of a container for supplying viscous material to the container, a valve member movably mounted in said body for movement into and out of closing engagement within said outlet for selectively establishing and disestablishing communication between said material inlet and said material outlet, a fluid passageway through said valve member having an outlet directed into said material outlet, and means operative upon movement of said valve member into closing engagement within said material outlet for supplying a momentary or premeasured blast of pressurized fluid through said passageway and said material outlet and into the neck of the container for discharging all of the viscous material from said material outlet into said container and for preventing coning of the viscous material in the neck of the container upon removal of the neck from said material outlet.
Claim 5
Independent Claim
194 words
A device for Filling a container with a viscous material, comprising a material outlet adapted to communicate with the inlet of a container, a chamber in communication with said outlet, means for supplying viscous material under pressure to said chamber for forcing said material through said outlet and into the container, a generally tubular valve rod mounted for reciprocation in said chamber axially of said outlet and carrying a tubular valve movable into and out of said outlet, said valve having an external surface in closed blocking engagement with said outlet when said valve is in said outlet, means for reciprocating said rod for moving said valve axially into and out of closed position in said outlet, means for supplying fluid under pressure to the interior of said tubular rod and valve, and means operative upon movement of said valve into closed position for delivering a momentary or pre-measured supply of said fluid through said rod, said valve and said outlet into the container for discharging residual viscous material from said outlet into the container and for preventing coning of the viscous material in the container when the container is removed from said outlet.
Claim 6
Independent Claim
194 words
A device for Filling a container with a viscous material, comprising a material outlet adapted to communicate with the inlet of a container, a chamber in communication with said outlet, means for supplying viscous material under pressure to said chamber for forcing said material through said outlet and into the container, a generally tubular valve rod mounted for reciprocation in said chamber axially of said outlet and carrying a tubular valve movable into and out of said outlet, said valve having an external surface in closed blocking engagement with said outlet when said valve is in said outlet, means for reciprocating said rod for moving said valve axially into and out of closed position in said outlet, means for supplying fluid under pressure to the interior of said tubular rod and valve, and means operative upon movement of said valve into closed position for delivering a momentary or pre-measured supply of said fluid through said rod, said valve and said outlet into the container for discharging residual viscous material from said outlet into the container and for preventing coning of the viscous material in the container when the container is removed from said outlet.
Claim 7
Dependent Claim
59 words
The device of claim 3 wherein said means for reciprocating said rod comprises a second chamber spaced from the first-named chamber and surrounding a portion of said rod remote from said valve, a piston on said rod within said second chamber, and means for alternately supplying pressurized fluid to said second chamber on the opposite sides of said piston.
Claim 8
Independent Claim
82 words
A device for filling containers with a material, comprising a body having a material inlet, a material outlet connected to said inlet, a valve member movably mounted in said body for movement into and out of closing engagement within said outlet for selectively establishing and disestablishing communication between said inlet and said outlet, a fluid passageway through said valve member having an outlet directed into said material outlet, and means for selectively supplying pressurized fluid through said passageway and said material outlet.
Claim 9
Independent Claim
82 words
A device for filling containers with a material, comprising a body having a material inlet, a material outlet connected to said inlet, a valve member movably mounted in said body for movement into and out of closing engagement within said outlet for selectively establishing and disestablishing communication between said inlet and said outlet, a fluid passageway through said valve member having an outlet directed into said material outlet, and means for selectively supplying pressurized fluid through said passageway and said material outlet.
