Abstract: A palletized shipping container (10) for bulk handling of liquids and fluent materials has a collapsible inner bag (30) enclosed in a flexible outer liner/bag (11) having rigid stiffener panels (20) in pocketed sides. The inner bag has a bung at its top end for filling or discharge and a valve fitment (50) near the bottom for receiving a discharge valve. Tape tabs (34, 19) at upper ends of the inner bag and outer liner/bag attach to the top panel and/or stiffener panels to maintain the bags in an erect uncollapsed configuration. The stiffener panels prevent bulging of the inner bag and provide vertical support, but their lateral sides are spaced apart and form non-structural “floating corners” to maximize volume, minimize shock, vibration and abrasive forces on the inner bag, yet maintain impact and compression strength meeting international certification standards. The bung is disposed beneath the top panel after filling the bag to prevent access and provide a tamper resistant assembly.

Abstract: A palletized shipping container for bulk handling of fluid materials has a rigid box-like outer shell within which is positioned a flexible bag and an intermediate corrugated liner sandwiched between the walls of the bag and shell. The bag has flap-like extensions at an upper end attached to the walls of the shell to maintain the bag in an erect uncollapsed configuration, a non-removable bung at its top end, and a non-removable discharge valve adjacent its bottom end. The bung is releasably retained at the top of the liner to maintain the bung in a proper position and prevent sagging of the bag. An inwardly and downwardly angled cushioned surface at the bottom of the shell supports the liner and bag, provides additional cushioning, facilitates emptying of the bag, and reduction of residual material. The pallet allows 4-sided entry of fork lift forks.
