Abstract
Abstract A roller chute apparatus for packaging a flexible plastic bag filled with liquid in a box has four stacks of rotatably supported vertically spaced rollers. The four stacks extend a substantial depth into the box around the inside of the box sidewalls forming two pair of mutually opposing stacks. A first pair extends above the open top of the box and cooperates with the second pair in guiding the bag into the box. The second pair extends above the top of the box with opposing stacks being mutually spaced a greater distance than opposing sidewalls of the box, thereby forming a funnel-like opening with the first pair. A driver roller is substantially located above and adjacent to the top of the box forming an angular transition between each of the portions of the second pair extending above and below the top of the box.

Claim 1
Independent Claim
175 words
A roller chute for packaging a flexible bag filled with liquid in a container having an open top and sidewalls, comprising: four stacks of rotatably supported, vertically spaced rollers, each of said stacks forming one of four sides of said chute, and each of said stacks having an upper portion and a lower portion, said lower portion stacks being oriented vertically; said upper portion stacks extending upward above respective lower portion stacks, at least one opposing pair of said upper portion stacks inclined relative to the corresponding pair of said lower portion stacks to form a funnel-like opening for guiding said flexible containers into the opening formed by said lower portion stacks, said inclined pair of upper portion stacks forming a junction with the corresponding pair of said lower portion stacks; and a pair of power driven rollers for urging said flexible bag into said container, said rollers located at said junction to maximize the contact area between said rollers and said flexible bag as said bag is urged to said container by said rollers.
Claim 2
Dependent Claim
