A shipper bag having at least one fluid chamber to facilitate fluid-assisted container evacuation from a product discharge zone of a product chamber. The product chamber is formed by at least one inner ply, and the least one fluid chamber disposed between the at least one inner ply and at least one second ply. The at least one fluid chamber has at least one seam connecting the at least one inner ply to the at least one second ply such that, when in the inflated state, the at least one seam comprises a first seam that extends from a location proximate the product discharge zone to a location proximate a location opposite the discharge zone. The bag may have two or more fluid compartments.

A collapsible bulk material container and sleeve configuration thereof are disclosed. The container includes a forming member assembly that provides container rigidity and stability and forms an internal geometric volumetric cavity for containing a bulk material load. A continuously woven sleeve having contiguous woven zones of selectable varied fabric weight and strength engage the forming member and provide the primary containment strength of the container. The sleeve engages the forming member either externally or internally. The sleeve includes a fabric weight zone of greatest strength adjacent the lower portion of the container.

The present invention relates to a big bag having a body having a plurality of sidewalls, an open top end, a closed bottom end, and a perimeter, wherein each one of the sidewalls connects with an adjacent sidewall forming a corner; a plurality of handles, each handle is connected to a corresponding corner; and a central handle connected to a middle section of the closed bottom of the body, wherein the central handle protrudes from the perimeter of the body.

In a storage container having a floor and a sidewall defining a space for a flowable material, and an inflatable liner attached at a first edge to the side wall along a line spaced from the floor, and attached at an opposite second edge to the floor along a line spaced from the sidewall, the inflatable liner adapted to be inflated to facilitate emptying the flowable material from the storage container, the improvement comprising a retraction system for retracting the liner as it is deflated.

A flexible tank is used to transport bulk liquids or semi-liquid materials inside of a multi-modal shipping container. It has water proof inner layers and an outer layer, which are formed and welded together to have seams at both ends of the flexible tank. A discharge valve is provided at one end of the flexible tank and an additional piece of material, referred to as a cape, is attached at the other end of the flexible tank. The flexible tank is situated in the container so that the end with the discharge valve is at the container opening and the end with the attached cape is at the rear of the container. The cape can be used by equipment positionable at the opening of the container to completely discharge the bulk liquids or semi-liquid materials from the flexible tank by pulling and winding up the cape and the layers of the flexible tank from the rear of the container.
