Abstract
A collapsible intermediate bulk container for liquid or freely flowable solid materials includes either a fabric outer/film liner bag or a bag of fabric reinforced elastomer. The bag is supported by a collapsible rigid frame which gradually collapses as the bag is emptied. The collapsible rigid frame includes a pallet-base portion that has an upper surface that is sloped to a center drainage point to facilitate complete emptying. The pallet-base portion contains a valve arrangement fixed to either the fabric outer bag (in the film-lined configuration) or to the reinforced fabric bag, at the center drainage point. The collapsed frame provides a compact return package. Either bag configuration may be reused or replaced in whole or in part.
