ABSTRACT:
A collapsible container for fluid materials such as liquids, slurrys, fine particulates and the like. The device includes a foldable box-like outer container and a blow molded synthetic resinous inner element in the form of a bottle which may be collapsed when empty and returned to a shipper with the outer container for reuse. The bottle is provided with a molded fitment adjacent to a lower edge of a side wall to which a dispensing valve may be fitted. In an another embodiment, the valve includes a corresponding fitment with a noncircular periphery which engages a liner element forming part of the container, in nonrotational relation, so that the dispensing valve may be conveniently threadedly attached thereto, without the use of tools. A third embodiment employs a nonreusable synthetic resinous bag as an inner element, and the dispensing valves includes a cutting edge which penetrates the bag upon installation.
