System for complete dispensing of flowable materials from a bulk shipping container
09862540 · 2018-01-09 · ·

The present invention is directed to a system for fully dispensing liquid from a bulk shipping container. The system includes a bulk bin and a cassette disposed therein. The cassette includes a cassette board, a liquid bag having inlet and outlet ports and an air inflated bag that is attached to the liquid bag. The air bag includes an air inlet port formed at one end thereof and used for inflating the air bag from a source of pressurized air. The air bag further includes an obstruction region defined by a weld line that is formed on an opposite end from the air inlet port to redirect the pressurized air within the air bag when inflating the air bag reaches a level at which the pressurized air counteract the liquid pressure within the liquid bag so as to urge the liquid toward the outlet port of the liquid bag.
