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.

The present disclosure provides a material feeding bag which comprises an inner bag. The inner bag has: an inner bag upper port portion, an inner bag main receiving portion and an inner bag lower port portion. The inner bag upper port portion has an upper port; the inner bag main receiving portion is connected to a lower end of the inner bag upper port portion along an axial direction; the inner bag lower port portion is connected to a lower end of the inner bag main receiving portion along the axial direction and has a lower port for controllable communication with an external hopper entrance. It doe not need to shear the material feeding bag by a scissors when materials is fed, so that it avoids generation of metal debris, and the mating and feeding material operation is fast and simple, and the working environment for an operator is improved.

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 storage device for packaging particulate solid substances or liquids, having a bottom and lateral walls defining a storage volume, includes: hanging loops toward the top intended for lifting an assembly including: a flexible external wrapper forming at least the four lateral walls of the storage volume, a flexible tubular internal wrapper secured to the four lateral walls of the external wrapper, dividing the storage volume into five vertical compartments including a central compartment defined by the interior volume of the internal wrapper, and four peripheral compartments defined between the lateral walls of the external wrapper and the lateral walls of the internal wrapper. The internal wrapper has an upper edge defining the upper mouth of the central compartment and a lower edge defining the lower mouth of the central compartment. The upper edge of the internal wrapper is at or below the upper edge of the lateral walls.

The invention is directed to a bag for transporting and handling powdery bulk materials, especially inorganic or organic pigments. Further, the present invention relates to a method for opening the tubular drain of such a bag, as well as to the use of the bag for transporting and handling powdery bulk materials.

A stitchless highly oriented polypropylene fabric bulk bag of the type that can hold 500 to 5000 pounds (226.7 to 2268 kilograms) of bulk material includes a highly oriented polypropylene fabric top, body and bottom, with a heat fused joint providing an air tight connection between the top and body, and another air tight heat fused joint connecting the body and bottom. A fill spout and discharge tube may also be provided with an air tight heat fused joint connecting the fill spout to the top and another air tight heat fused joint connecting the discharge spout to the bottom. Heat sealing machinery include heat seal bar assemblies that can self-align during heat-sealing to apply even pressure to all areas being heat sealed. A heating element is of single piece construction and can include end coupler portions as part of the single piece construction. Carrier plates used in a heat-sealing assembly line guide parts placement, provide quality checks for parts placement, and tooling set-up for machinery.

A bottom and discharge assembly for a flexible fabric bulk bag of the type having heat sealed joints includes a piece of reinforcing fabric positioned under a heat sealed joint of a bottom portion and a discharge tube, around a periphery of a discharge tube opening and bottom opening that are each substantially square, wherein the reinforcing fabric prevents bag failure at or about at corners of the bottom opening and discharge tube opening. The assembly can be formed by overlapping the reinforcing fabric, discharge tube, and bottom portion so that the bottom is heat sealed to both a portion of the discharge tube fabric and a portion of the reinforcing fabric and wherein a portion of the reinforcing fabric is under the discharge tube and bottom joint, and wherein the discharge tube fabric and reinforcing fabric are not joined together.

The device relates to transportation and storage of bulk cargoes and comprises a vessel with upper charging opening and lower discharging opening, bearing framework and discharging mechanism, the device being further provided with soft sling load distribution ring, which passes through additional external loops of the main slings and alternately through additional loops along the upper perimeter of the cylinder, which, in turn, are embodied in the form of the load distribution triangle. The device provides improving convenience of handling multi-tonnage bulk cargoes as well as improving container reliability in use.

The invention described herein generally pertains to a system and method related to a hermetic seal assembly used with a bag to provide a hermetic seal for the bag that can be opened and closed while maintaining the hermetic seal for the bag and materials stored therein. The hermetic seal assembly can include a lid and a collar, wherein the collar can be releasably affixed to the bag or integrated into an opening of the bag.

A material bag includes a bag body and a sleeve on the bag body. A periphery of an opening of the sleeve is provided with a plurality of flexible tabs. An interval is defined between every two of the tabs. The tabs are separated from each other by the interval and connected to the periphery of the opening of the sleeve, so they can be independently flipped to form force-bearing faces to be clamped by a clamping device. When the folded material bag is used for powder/particle material packaging, the clamping device will act on the tabs for clamping the sleeve of the material bag. The clamping device can complete the transfer of the material bag and the connection between the sleeve of the material bag and a filling cylinder.
