Abstract
Abstract This disclosure relates to the filling of flexible containers with compacted finely divided materials utilizing a filler of the pressure differential type. During the filling of the container, the container is pneumatically supported to establish and maintain a predetermined shape and volume whereby finely divided material of a constant density may be compactly placed therein to obtain a filled container having therein a predetermined weight of the material without weighing the material. Another feature of the apparatus is that in the absence of a container, although a filler may be actuated to dispense material, no dispensing will take place. A further feature is the relationship of the filler to a carton having upstanding flaps and a liner wherein the carton may be filled to overflowing, but wherein the material in the carton has a recess due to the shape of the filler, and wherein in the normal closing of the carton, the overflowing material may be automatically displaced into the recess to provide for a completely filled carton.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
An apparatus for filling a flexible container with compacted finely divided material, said apparatus comprising a shroud for receiving a container and a filler of the pressure differential type, said shroud including sealing means for sealing engagement with the exterior of a container and pneumatically supporting a container during the filling thereof to establish and maintain a predetermined shape of the container and the volume thereof, said filler including a housing having a portion thereof receivable in a coNtainer, and said housing portion having sealing means for sealing engagement with the interior of a container, said filler including a pneumatically operated valve member requiring a seal between said housing portion and a container for the opening of said valve member whereby said filler is of the no-container nodispensing type, said pneumatically operated valve member being in the form of a plurality of resilient flaps normally preventing material flow through said filler and movable to flow permitting positions in response to the drawing of a vacuum through said housing and in a container being filled.
Claim 2
Independent Claim
174 words
An apparatus for filling a flexible container with compacted finely divided material, said apparatus comprising a shroud for receiving a container and a filler of the pressure differential type, said shroud including sealing means for sealing engagement with the exterior of a container and pneumatically supporting a container during the filling thereof to establish and maintain a predetermined shape of the container and the volume thereof, said filler including a housing having a portion thereof receivable in a coNtainer, and said housing portion having sealing means for sealing engagement with the interior of a container, said filler including a pneumatically operated valve member requiring a seal between said housing portion and a container for the opening of said valve member whereby said filler is of the no-container nodispensing type, said pneumatically operated valve member being in the form of a plurality of resilient flaps normally preventing material flow through said filler and movable to flow permitting positions in response to the drawing of a vacuum through said housing and in a container being filled.
Claim 3
Dependent Claim
35 words
The apparatus of claim 1 wherein said apparatus is particularly adapted for filling a container in the form of a carton of a rectangular section, and said shroud being split diagonally of the intended carton.
Claim 4
Dependent Claim
30 words
The apparatus of claim 1 wherein said shroud has an interior wall configuration for providing overall contact with a container while still providing for a minimal contact with a container.
Claim 5
Dependent Claim
105 words
The apparatus of claim 1 wherein said apparatus is particularly adapted for filling a container in the form of a carton having a body, upstanding closure flaps and a liner and wherein a seal may be formed with the liner above the body, and wherein said filler is proportioned to position said sealing means thereof above the carton body whereby a carton may be filled to overflowing with a cavity left in the material disposed in the body due to the filler and wherein the overflowing material may be displaced into the cavity during the folding of the carton closure flaps to seal the carton.
Claim 6
Independent Claim
238 words
An apparatus for filling a flexible container with compactly finely divided material, said apparatus comprising a shroud for receiving a container and a filler of the pressure differential type, said shroud including sealing means for sealing engagement with the exterior of a container and pneumatically supporting a container during the filling thereof to establish and maintain a predetermined shape of the container and the volume thereof, said filler including a housing having a portion thereof receivable in a container, and said housing portion having sealing means for sealing engagement with the interior of a container, said filler including a pneumatically operated valve member requiring a seal between said housing portion and a container for the opening of said valve member whereby said filler is of the no-container no-dispensing type, said apparatus being particularly adaptable for filling a container in the form of a carton of a rectangular section and having a body, upstanding closure flaps and a liner wherein a seal may be formed with the liner above the body, said filler being proportioned to position said sealing means thereof above the carton body whereby a carton may be filled to overflowing with a cavity left in the material disposed in the body due to the filler and wherein the overflowing material may be displaced into the cavity during the folding of the flaps to seal the carton, and said shroud is split diagonally of the intended carton.
Claim 7
Independent Claim
238 words
An apparatus for filling a flexible container with compactly finely divided material, said apparatus comprising a shroud for receiving a container and a filler of the pressure differential type, said shroud including sealing means for sealing engagement with the exterior of a container and pneumatically supporting a container during the filling thereof to establish and maintain a predetermined shape of the container and the volume thereof, said filler including a housing having a portion thereof receivable in a container, and said housing portion having sealing means for sealing engagement with the interior of a container, said filler including a pneumatically operated valve member requiring a seal between said housing portion and a container for the opening of said valve member whereby said filler is of the no-container no-dispensing type, said apparatus being particularly adaptable for filling a container in the form of a carton of a rectangular section and having a body, upstanding closure flaps and a liner wherein a seal may be formed with the liner above the body, said filler being proportioned to position said sealing means thereof above the carton body whereby a carton may be filled to overflowing with a cavity left in the material disposed in the body due to the filler and wherein the overflowing material may be displaced into the cavity during the folding of the flaps to seal the carton, and said shroud is split diagonally of the intended carton.
