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 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.

A lifting assembly and method for a flexible bag includes one or more lift members, wherein each lift member is coupled to a layer of material, e.g., a fabric layer. The fabric layer can be coupled to a flexible bag wherein the fabric layer is an intermediate layer between the lift member and the flexible bag. The fabric layer can be heat fused or otherwise coupled to a bag without stitching or sewing, which eliminates the creation of sew or stitch holes that breach a containment area of the bag and which can weaken the bag fabric. The one or more lift members, however, can be sewn or stitched to one or more intermediate layers.

A device comprising a hook and magnet. The hook is configured to move between a folded position, such that the space below the magnet is free, and a deployed position, such that the hook is below the magnet. The magnet is activated to attract a ferromagnetic piece connected to a support handle of a container.

A rope fixture 11 fixes a closing rope 12 for binding a bag opening of a flexible container bag 20A as a bag body, and includes a plate-shaped body in which a through-hole and a slit are formed, wherein a through-hole 13 allows the closing rope 12 to pass therethrough and a slit 14 nips and locks the closing rope 12 and has an insertion opening 17 provided at one end located at a lateral side of the plate-shaped body 15 and has a rope locking portion 18 allowing the closing rope 12 to pass therethrough and locks the closing rope 12 provided at the other end.
摘要:
A method of lifting a loaded bag with a coupled lifting sling. The bag has a top portion, a closed sidewall, a closed bottom portion, and an opening on the top portion. The method uses a lifting sling coupled to the bag, where the lifting sling is a series of straps that holds the bag. The bag has a series of strap retention devices attached near the bags top edge. The straps are movable vertically in the retention devices. The method includes the steps of loading the bag with a load to a load level, then lifting the lifting straps using a lifting device. The bag's surface above the load line slides down the coupled straps, as the straps are coupled but not attached to the bags above the load line.

An improved bulk bag for containing dry bulk, granular, and/or pulverized materials designed to prevent dust cloud escape and migration during discharge/emptying of the materials in bulk bag using an integrated dust barrier skirt affixed to the exterior of the bulk bag and telescopable to create a dust cloud curtain prior to content discharge.
摘要:
A lifting bag having at least one side wall and a closed bottom forming an interior, the bag further having a closable top portion connected to the sidewall and adapted to close the interior of the bag. The opening is a single slit centered on the bag top and closable with a zipper. The lifting bag includes a sling coupled to the bag, generally through a edge strip positioned at ore near the top edge of the bag. The bag can be constructed from a single multilayered sheet. The bag is used in conjunction with a lifting strap system.
