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.

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. The lid can include a sampling port and a corresponding removeable cap.

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.

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.

The invention relates to a container (1), in particular package, for transporting a powder/granular product, comprising: a flexible inlet/outlet (2) which, as intended, is clamped with a distal end portion (22) to a connecting device in order to fill the product into the container (1) or to empty the container (1), the distal end portion (22) having a different, in particular more flexible, construction than another portion of the inlet/outlet (2).

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 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 collection assembly (10, 10a) for flowable materials includes a central, flexible bag (12, 12a) with a collection skirt (14, 14a) secured to the bag (12, 12a) and extending outwardly from the open top (20, 20a) of the bag (12, 12a). In use, the assembly (10, 10a) is placed at a collection site with the bag (12, 12a) in a collapsed condition and the skirt (14, 14a) is deployed about the bag (12, 12a). Material (36) is then placed on the assembly (10, 10a) over the open top (20, 20a) and, as necessary, the skirt (14, 14a). The skirt is then elevated using marginal gathering apparatus (16, 16a), thereby causing the material (36) to flow into the bag (12, 12a). The skirt (14, 14a) may then be gathered and closed, forming a duffel closure for the assembly (10, 10a).

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 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.
