An apparatus for storing or transporting flowable materials or other materials, such as diesel fuel, includes a container and a support. The container is supported by the support. The support sits on or is mounted across an upper part of an open top wagon or vehicle, such as a railway wagon or truck or trailer used for transporting bulk commodities. The apparatus is movable between an expanded configuration in which the container is expandable into a lower part of the wagon or vehicle and a collapsed configuration in which the container is collapsible to the support. The weight of the support and the container is borne by the upper part of the wagon or vehicle when the container is in its collapsed configuration and the apparatus is positioned on the wagon or vehicle.

A flexible tank has one or more inner layers and one or more outer layers enclosing the inner layers. It has an improved structure to prevent leakage and rupture when making a long multi-modal shipment of large quantities of a liquid, including when the flexible tank is not supported by the end or side walls of a shipping container.

A dumpster bag has: a flexible bag member including a bottom and a sidewall structure extending upward from the bottom to a rim; at least one rim stay comprising a bungee pole; and at least one corner stay.

System and method for loading cargo onto an unmanned aerial vehicle (UAV). One embodiment is a cargo pod for an unmanned aerial vehicle (UAV). The cargo pod includes a hollow body that forms a section of a fuselage of the UAV, and further includes a latching mechanism that releasably secures the hollow body with the fuselage of the UAV.

Systems and methods are provided for safely and efficiently transporting granular material. In one embodiment, a container for granular material is provided. The container can have a top plate and a bottom plate that are coupled to one another via one or more high-strength fabric sleeves. The bottom plate can include a discharge valve for discharging the granular material in the container. The container can also include a discharge bladder that, when inflated, biases granular material within the container toward the discharge valve. The container can also include at least one barrier positioned proximate the discharge valve such that the barrier prevents at least a portion of the discharge bladder from entering the discharge valve. The barrier can allow sand or other granular material to pass through the barrier and exit through the discharge valve.

A flexible tank has an inner tank and at least one end closure with alternating interlaced hollow loops from two separate exterior layers. A nylon rope or similar securing element is passed through the hollow loops to use the exterior layers in an end closure to constrain the inner tank. An end flap may be welded to an exterior layer and positioned between the inner tank and the end closure. The hollow loops may be formed by folding over the exterior layers and cutting out complementary portions so the loops are in an alternating interlaced pattern.

A portable storage bin includes a base frame on the ground and a bin support frame operable relative to the base frame between a working position and a transport position which is reduced in height relative to the working position, and a storage envelope supported on the bin support frame to define a storage chamber for storing particulate material therein in the working position of the bin support frame in which the storage envelope is collapsible with the bin support frame from the working position to the transport position. The bin support frame has an upper frame portion from which the storage envelope is suspended in the working position and a central support post which is extendable in height between the upper frame portion and the base frame for raising the envelope from the transport position to the working position.

A container may comprise a support frame with sides and at least one of the sides being an open side defining an opening, a flexible panel configured to at least partially cover the open side of the support frame, and a panel mounting assembly configured to removably mount the panel over the opening. The panel mounting assembly may comprise at least one panel mounting element including a leverage structure configured to provide a fulcrum edge along at least a portion of the opening, with the at least one portion of the panel being tensionable over the fulcrum edge. The panel mounting element may also comprise a tensioning structure mountable on the leverage structure and configured to selectively apply tension to the at least one portion of the panel with the thicker thickness over the fulcrum edge of the leverage structure.
