A bag for the storage and transport of a pulverulent product, such as agri-food, mineral, chemical or pharmaceutical powders and like powdery materials, the bag including a bottom part, a sidewall, and an upper part joined together to form a storage volume, wherein the upper part is provided with a filler inlet configured to allow the pulverulent product to be introduced inside the storage volume during a filling operation. The bag further includes lifting straps, and at least one integral elongated section made of an air-permeable material extending inside the storage volume and including an outlet accessible from the outside of the bag, the elongated section acting as an integrated filter member configured to allow insertion of an elongated air-extraction member of an air-extraction system inside the elongated section so as to extract air directly from inside the storage volume of the bag during the filling operation.

A tamper-evident device for valves comprises: an anti-theft buckle (1), provided with an anti-theft buckle body (17), a pulling portion (4), a tearable portion (5), an elastic hook (7), and a position limiting surface (6); an anti-theft cover (2), provided with a position limiting contour (8) and a hook receiving portion (9); and a position limiting slot (10) provided at a passage outlet (13) of a valve body (3). During use, the anti-theft cover (2) is connected to the passage outlet (13), and the elastic hook (7) is hooked to the hook receiving portion (9) and fitted to position limiting slot (10) to limit relative positions of the anti-theft cover (2) and the valve body (3). Also disclosed is a valve having the temper-evident device. The temper-evident device is easy to open and can effectively prevent stored materials from being stolen.

A fabric bulk bag and a method for constructing the same, the bag including a continuous sidewall, a top portion, and a bottom, all defining a bulk storage space therein; the bottom further comprising eight sides which define an octagonal shape having an enlarged footprint so that the bag wall is sewn to the bottom in less time than a round shaped bag, yet when filled stands more upright with less tendency to lean than the current square shaped bags thereby providing a safer more dependable stacking bulk bag. In the method of producing the fabric bulk bag, the bag is constructed in less time than the prior art round bottom bags, uses less wall fabric than prior art square bottomed bags and when constructed and filled, supports itself more stable on a floor or pallet because it provides substantially more base for the product to rest on. In other embodiments, the bag would be multi-sided with greater than four sides.

The present invention is directed to a system for fully dispensing liquid from a bulk shipping container. The system includes a bulk bin and a cassette disposed therein. The cassette includes a cassette board, a liquid bag having inlet and outlet ports and an air inflated bag that is attached to the liquid bag. The air bag includes an air inlet port formed at one end thereof and used for inflating the air bag from a source of pressurized air. The air bag further includes an obstruction region defined by a weld line that is formed on an opposite end from the air inlet port to redirect the pressurized air within the air bag when inflating the air bag reaches a level at which the pressurized air counteract the liquid pressure within the liquid bag so as to urge the liquid toward the outlet port of the liquid bag.

A bulk bag includes a bulk bag body that is configured to have a varying circumference with a reduced circumference between the top and bottom of the bulk bag body to reduce bulging when the bulk bag body is filled with content.

A flexible fire-resistant container comprising a woven material coated or impregnated with a fire-resistant coating, especially where the fire-resistant coating comprises vermiculite, and optionally where the woven material is made from fibreglass or fibres thereof, silica glass or fibres thereof, or ceramic glass or fibres thereof; and methods for the production of such a container.

Systems and methods for efficiently managing bulk material are provided. The disclosure is directed to a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender hopper. The portable support structure may include a frame for receiving and holding the one or more portable bulk material containers in an elevated position proximate the blender hopper, as well as one or more gravity feed outlets for routing the bulk material from the containers directly into the blender hopper. In some embodiments, the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit. In other embodiments, the portable support structure may be a mobile support structure that is integrated into a trailer unit.

The present invention relates to Flexible Intermediate Bulk Containers (FIBC) having a body made of flexible fabric woven from polymeric tapes, and transport loops, wherein the body comprises side walls, bottom and top parts, characterised in that the fabric of at least one of the side walls and transport loops is woven from uniaxially-drawn PET tape having a density greater than 1.333 g/cm.sup.3.

A bag configured to contain and transport bulk material includes at least one through-hole positioned at an upper portion of the bag to facilitate ingress/egress of a hoist-member of a hoisting machine. Other embodiments include a spout located at a bottom-side portion of the bag or at a base of the bag, and inserts placed at a base of the bag to form a desired contour to generate a gradient by which the material may flow. The inserts may be temporarily placed at the base or permanently affixed thereto. Further embodiments may include a contoured base without the use of inserts to generate the gradient. Methods of use include stacking and handling the bags without requiring an operator in addition to the one operating the hoisting machine or requiring the hoist machine operator to interrupt operation of the hoist machine to rig the bag to the hoist machine.
