Abstract
Abstract An apparatus for filling a flexible container with a liquid from a reservoir or tank having a plurality of filling nozzles or tubes. The container engages a nozzle or tube as it is being filled and is subjected to a filling head pressure that causes the sides of the container to distend or expand thus enlarging its volumetric capacity. A control, including a plunger or projector, is provided to engage and indent or compress a side of a container to adjust the volumetric size of the container during the filling operation. Thus, when the head pressure is removed from a filled container, the plunger or projector is moved away from or out of engagement with the side of the container whereby the contraction of the sides of the container will not result in an overflowing or spilling of the contents of the container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
In a container filling device embodying a rotating turret with pedestals for supporting flexible containers during the filling of said containers from a reservoir having filling valves and means for adjusting the volumetric size of said containers during the filling operation, said means comprising; a cam member, a roller mounted on each pedestal and engagable with said cam for moving said pedestal away from a filling nozzle upon the filling of said container, a lever, means for pivotally supporting said lever with respect to said cam, said lever having an upper end and a lower end a plunger mounted in the upper end portion of said lever, said lower end of said lever having means thereon engagable by said roller for moving said plunger against said container to compress at least one side of said container contemporaneous with the removal of said container from said filling valve.
Claim 2
Dependent Claim
147 words
In a container filling device embodying a rotating turret with pedestals for supporting flexible containers during the filling of said containers from a reservoir having filling valves and means for adjusting the volumetric size of said containers during the filling operation, said means comprising; a cam member, a roller mounted on each pedestal and engagable with said cam for moving said pedestal away from a filling nozzle upon the filling of said container, a lever, means for pivotally supporting said lever with respect to said cam, said lever having an upper end and a lower end a plunger mounted in the upper end portion of said lever, said lower end of said lever having means thereon engagable by said roller for moving said plunger against said container to compress at least one side of said container contemporaneous with the removal of said container from said filling valve.
Claim 3
Dependent Claim
48 words
In a container filling apparatus as set forth in claim 1 wherein said first named means includes a stud carried by said cam with said lever pivotally mounted on said stud and said last named means includes a shoe member carried by the lower end of said lever.
Claim 4
Dependent Claim
51 words
In a container filling apparatus as set forth in claim 2 wherein said stud has means mounted thereon and engageable with said lever for positioning said lever on said stud to define the position of said shoe member with respect to the path of movement of said roller on said cam.
Claim 5
Dependent Claim
47 words
In a container filling apparatus as set forth in claim 3 wherein a spring member is connected to said end portion of said lever and to said stud to withdraw said plunger away from said container as said roller moves out of engagement with said shoe member.
Claim 6
Dependent Claim
35 words
In a container filling apparatus as set forth in claim 2 wherein a bracket is secured to said cam and said stud is adjustably mounted in said bracket in spaced parallel relation to said cam.
Claim 7
Dependent Claim
30 words
In a container filling apparatus as set forth in claim 5 wherein said stud is provided with a pair of spaced collar members for positioning said lever upon said stud.
Claim 8
Independent Claim
125 words
An apparatus for controlling the volumetric capacity of a fluid in a flexible container during the filling of the container with liquid from a reservoir having a depending nozzle comprising a pedestal for supporting said container and moving same into and out of engagement with said nozzle, a cam member, a roller carried by said pedestal and engagable with said cam, a stud secured to said cam in spaced parallel relation therewith, a lever pivotally mounted on said stud, one end of said lever projecting above said pedestal, a plunger in said end, the other end of said lever engagable by said roller for moving said plunger against said container to compress a side of said container and reduce the volumetric capacity of said container.
Claim 9
Independent Claim
125 words
An apparatus for controlling the volumetric capacity of a fluid in a flexible container during the filling of the container with liquid from a reservoir having a depending nozzle comprising a pedestal for supporting said container and moving same into and out of engagement with said nozzle, a cam member, a roller carried by said pedestal and engagable with said cam, a stud secured to said cam in spaced parallel relation therewith, a lever pivotally mounted on said stud, one end of said lever projecting above said pedestal, a plunger in said end, the other end of said lever engagable by said roller for moving said plunger against said container to compress a side of said container and reduce the volumetric capacity of said container.
Claim 10
Dependent Claim
40 words
An apparatus as set forth in claim 7 wherein a spring member is connected to said stud and lever to withdraw said plunger from said container as said roller moves out of engagement with said other end of said lever.
