A flexible container for the storage of liquid, where a liquid medium to some extent or completely surrounds the flexible container, characterized in that the base of the flexible container proceeds in the manner of a cone to a discharge point at which liquid can be discharged from the flexible container.

A foldable water tank comprises a foldable receptacle including an open receptacle portion and a closed receptacle portion, the open receptacle portion communicating with the closed receptacle portion such that water from the open receptacle flows to the closed receptacle, the open receptacle portion including side walls; a folding frame operably associated with the side walls to support the sidewalls in an upright position; and the closed receptacle portion extending outwardly from the frame.

In one embodiment, a collapsible, flexible storage tank is provided that is capable of holding a liquid material. The tank includes a sheet of flexible, moisture impervious side wall material; at least one opening for receiving a fitting to fill and drain the tank; joining seams wherein edges of the sheet are joined, the seams extending about the tank in a spiral orientation; and closing seams wherein the side ends of the pillow tank are sealed. In another aspect, a collapsible, flexible storage tank is capable of holding a liquid. The tank includes a sheet of flexible side wall material; at least one opening for receiving a fitting to fill and drain the tank; and butt seams wherein edges of the flexible sheet are joined together in the same plane in a butt joint configuration using an overlapping piece of flexible, moisture impervious sealed material over the top thereof.

The invention relates to a transport bag comprising a base, a top portion, and side walls extending between said base and top portion in such a way that a volume for storing granule, fluid, viscous, or semi-fluid materials is formed, wherein the transport bag comprises at least one narrowed portion extending through a middle axis of said side wall from a upper edge to a bottom edge of the side wall.

A freight vehicle has a cargo space that is convertible for handling piece goods and is also suitable for hauling liquid bulk material. A conventional cargo space is equipped with a drop-down frame and flexible liquid enclosure that is stowed in the ceiling of the trailer while hauling a full load of palletized or piece goods materials that can be lowered to the floor for transporting liquid bulk loads. Generally, the long tubular (round and or oval in shape from an end view) can be fitted with a polyethylene film disposable liner. The disposable poly liner will ensure the liquid freight is free from contamination. This concept not only eliminates the need for a liquid tanker to be washed out between each load but also allows for the hauling of piece goods freight when the frame system is raised back to the ceiling.
