A container-dedicated bulk bag for convenient loading and unloading includes a bag body, and two forklift-specific fork guide tubes. The two forklift-specific fork guide tubes pass through an upper end of the bag body and are respectively fixed on two inner side walls of the upper end of the bag body. In use, forks of a forklift are inserted directly into the two forklift-specific fork guide tubes to quickly fork and lift the bulk bag. The bulk bag can facilitate the operation of the forklift, and improve the load-bearing characteristics and stability.

A container includes a robust semi-rigid main bag, a tarpaulin top section, and ties on the main bag. The main bag has a base and side panels for containing bulk garden products. The top section engages an upper portion of the main bag and has an opening. When open, it enables access into the main bag. When selectively closed, the top section protects the bulk garden products against outside elements. The ties can selectively tie down the top section and enable clear and ready access into the main bag containing the bulk garden products. Ties located about midway down the main bag, after it has been emptied of about half the bulk garden products, can also selectively tie down the upper portion for continued clear and ready access to any bulk garden products that then remain in the main bag.

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 fillable with a liquid having a base and at least one enclosing wall. The base has an upper surface and a lower surface, and defines a plurality of edges and a perimeter. The enclosing wall extends about the base and is attached thereto to, together with the base, define an enclosure. The inner brace assembly comprises at least one inner support member having a base wall attachment side and an encasing wall attachment side. The base wall attachment side is attached to the base spaced apart from the perimeter. The encasing wall attachment side is attached to the at least one enclosing wall spaced apart from the base fold.

Reusable, flexible, lightweight, low cost flexible intermediate bulk containers (FIBCs) for the delivery of granular proppant material for fracing that will allow the transport of higher weights of proppant, such as sand, per truck load. The invention includes a container made of a high strength, flexible material with a top opening for loading and deploying the proppant. The container can be lifted and deployed with a fork truck or crane. Alternatively, proprietary deployment systems, such as a conveyor system, can be used to quickly and efficiently deploy the proppant from the container at a desired site.

A bag for the transport and storage of bulk goods including: at least a bottom, four sides connected along adjacent edges to form vertical ridges at each of the four corners of the bag and each side connected to a lid along an upper edge to form a horizontal ridge; four lifting straps each having a first and second sections separated by an intermediate section and sewn on a vertical ridge of the bag, and with the intermediate section forming an oblong loop and positioned along the horizontal ridge of the bag; and four restraining straps each having two vertical sections separated by a U-shaped section, and with each vertical section sewn on one side of the bag and the U-shaped section positioned over the intermediate section of a lifting strap and at least partially sewn thereon, and wherein the restraining straps are configured to limit extension of the top of the loops formed by the intermediate sections of the lifting straps in the vertical direction.

An apparatus for forming a shipping container comprises a tubular body extending between top and bottom ends, first and second bottom panels extending from the bottom end, the first and second bottom closing panels rotatable from a co-planar configuration with the tubular body to a position extending perpendicularly across the bottom of the tubular body and at least one fastener adapted to secure the bottom closing panels across the bottom end of the tubular body. The shipping container may also be formed by a planar body having top and bottom surfaces wherein the top surface is adapted to support a load, at least one pocket extending across the bottom surface and at least one spacing element sized to be received within the pocket. The apparatus may include at least one rigid body between the top and bottom surfaces of the planar body and side walls extending upwardly therefrom.
