Abstract
Abstract A flexible container filling machine handles individual containers by severing the leading container from a continuous web of such containers which is fed into the filling machine. Each container includes a spout communicating with the interior of the container and a cap for closing that spout. The cap and spout of the leading container are pushed to a filling station where they are engaged by a cap handler and spout holder, respectively. The leading container is then severed from the web. A discharge chute, including a releasable container support, is positioned beneath the severed container and a supporting carton is positioned and elevated beneath the discharge chute. The cap is removed from the spout of the severed leading container and the severed container is filled with a metered amount of liquid. The cap is returned to close the filled container. The cap, spout and container support are then released to allow the filled container to fall into the waiting support carton.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
239 words
Apparatus for filling individual flexible containers severed from a continuous web of said containers and depositing containers so filled into supporting cartons, said containers each including a spout communicating with the interior of its associated container and having a separable capping device connected to said spout, said apparatus comprising: means for receiving said continuous web of containers from a supply force, including means for engaging the spouts of said containers to position and align said web of containers and means for retaining said web of containers within said apparatus; pusher means adapted to engage the spout of the leading container of said web for advancing said web so that the the spout of said leading container is positioned at a filling station; container separating means for severing said leading container from said web; filling means at said filling station for filling said severed leading container; cap handling means for removing said capping device from said leading container prior to being filled and for replacing said capping device onto said leading container after it has been filled; container discharge means, expanding in cross-sectional area toward the discharge end, for discharging a filled container under the influence of gravity; and carton receiving means positioned under said discharge means for positioning a rigid carton such that the open end of said carton surrounds the expanded cross-sectional area end of said discharge means so as to receive a filled container within said carton.

Claim 5
Dependent Claim
17 words
The apparatus of claim 3 further including means for ejecting cartons containing filled containers from said apparatus.
