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.Field of SearchEndless conveyor for receptacleWith separate closure Filling preformed receptacle and subsequent covering Separate closure applying With receptacle support and/or feed by shoulder engagement Opening prior to filling and closing Flexible, expandable receptacle (e.g., bag, tube) Plural covers With separate closure attaching (e.g., cap or plug) Guide or inserted form or support for article contents Closing preformed container deformed by contents Opening only With common fill-close stations Swivel or slide relation to receptacle aperture Common infeed means for fill and close means Bag or sack | |
