Abstract: The present invention is a reliable, lightweight, environmentally friendly, highly reusable, highly durable, fully collapsible container for use in transporting solid and liquid materials, including those materials governed by the dangerous goods code of the UN regulations. The container employs a selectively sealed lid, a truss system for preventing bulge at the rim of the container so that the rim remains within the footprint of the lid, and an integrated closure system for securing transported contents.

Abstract: The present invention is directed to a collapsible drum for transporting materials. The present invention solves problems associated with reusing and efficiently transporting shipping containers designed for retaining bulk materials, including hazardous substances, and insuring reliable structural integrity with every use. The collapsible drum of the present invention is adapted for integration with standard handling equipment, and has a permanently secured, collapsible drum floor and fluted sidewalls that enable an operator to collapse and roll the empty drum into a compact tube. The collapsible drum provides one or more removable, ribbed disc-shaped inserts for reinforcing the drum floor and/or drum lid.

Abstract: The present invention includes a collapsible container defined by a continuous rigid structure and an interior liner that is uniformly affixed thereto. The continuous rigid structure is preferably four-sided such that it defines four continuous surfaces of a cube. The continuous rigid structure is collapsible due to at least one scoring line defined on at least one surface thereof. The liner is integrally affixed to each of the four sides and additionally provides a fifth side that forms the bottom of the container. A protective cover is secured to the exterior of the continuous rigid structure for protecting the contained materials against the elements. The cover can be selectively sealed for rendering the container of the present invention substantially impervious to the elements.

Abstract: A container for retaining bulk materials for storage and/or transport. The container includes improvements over existing collapsible containers designed for the same purpose. The container of the present invention includes an impervious liner for receiving and retaining within the container bulk materials for which contact with reactive fluids is undesirable. Such bulk materials include, but are not limited to, spent catalysts. The impervious liner is preferably made of a material such as a polypropylene/nylon/polypropylene blend. An additional feature of the present invention is a weather-blocking cover that is adapted to be connected to the walls of a bulk container that may or may not be collapsible. The weather-blocking cover is adapted to seal off upper surfaces and edges of the container so that the container may be stored externally for extended periods without fear that precipitation will seep into the interior of the container.

Abstract: A container is assembled from several panels generally comprised of one or more layers of relatively rigid stiffening material (such as corrugated cardboard) sandwiched between two layers of a strong, flexible material, such as woven polypropylene. These panels form four side wall assemblies and, in combination with a flexible bottom panel, form a self-supporting, generally cubic material receiving box. An integral closure assembly, including cover flap, front flap and side flaps, advantageously enable the container to conveniently and safely secure relatively large volumes of dense debris without spillage even when the fully laden container is dropped during handling. The container, when empty, may be collapsed for convenient storage.

Abstract: A collapsible, bag-like container, that incorporates the features of a rigid, free-standing container, with the flexibility and collapsibility of a bulk bag. Stiffening members are placed into pockets, created by sewing together two sheets of woven polypropylene. The stiffening members may be removed and placed inside the bag for shipping, and then installed in the sewn pockets to create a collapsible container, suitable for containment, and shipment, of bulk materials of up to seventy (70) percent liquid composition. The container side walls have flaps that can be folded onto the top of the container, and tied together with flexible tie elements, such that the container has a desired transverse reinforcement.
