Abstract: A bag for the transport and storage of bulk goods including a main body having at least a bottom part and four sides connected in pairs along adjacent edges to form vertical ridges at four corners of the bag. The bag further includes four lifting straps, each having first and second end sections and an intermediate section rising above a top surface of the bag. The lifting straps are interconnected in pairs by two sleeves to form tubings or ducts extending longitudinally along a top surface of the bag to allow lifting of the bag by means of a forklift. The sleeves are connected to the main body of the bag via the lifting straps and are not attached longitudinally to the main body of the bag. Furthermore, the first and second end sections of each lifting strap are secured to corresponding sides of the bag.

Abstract: 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.

Abstract: There is disclosed a bag for the transport and storage of bulk goods or liquids formed by the assembly of several double-thickness pieces of fabric, including first and second pieces of fabric, each having opposite first and second sides extending between first and second folded-in flattened edges. Each piece of fabric includes at least one gusset defined by a first oblique section extending between the first folded-in flattened edge and a first gusset end positioned on the second side of the piece of fabric and a second gusset end positioned on the first side of the piece of fabric. The first and second pieces of fabric are assembled such that the second side of the second piece of fabric is in contact with or close to the first side of the first piece of fabric such that the first and second gusset ends of the first and second pieces of fabric are substantially aligned.

Abstract: The present invention relates to a method for production of bags for the transport and storage of bulk goods or liquids, wherein use is made of tubular fabric cut into several pieces, which are then assembled together, including the steps of: providing a tubular fabric; flattening the tubular fabric to form a first double-thickness fabric having two opposite sides, respectively an internal side and an external side, extending between two flattened edges; folding-in or pleating at least one of the flattened edges of the double-thickness fabric to form a gusset; cutting the tubular fabric into pieces and assembling the pieces to form a bag; wherein the assembly of two of the pieces includes the steps of: assembling the first and second pieces by means of seams formed around or near first to fourth gusset ends.

Abstract: Bag having at least one of its sides produced from a piece of fabric secured to a piece of bubble wrap; securing being achieved by coating one face of the piece of fabric with adhesive then applying a piece of bubble wrap, either via its bumpy face or via its smooth face. Attachment is performed by sewing, laminating or bonding a second piece of fabric to the first piece of fabric so as to sandwich a piece of bubble wrap between these two pieces of fabric.

Abstract: The device for stabilizing drain and/or fill valves for a flexible container for conveying liquids or pulverulent materials is characterized by use of a non-strictly cylindrical valve comprising at least one of the following three members: a lug in a low position formed by an extension of a through valve key, a polygonal proximal flange or a partially polygonal protuberance, and in that a stabilizing plate has both a recess corresponding to and following the shape of the said chosen member, and two pads of loops and hooks stuck to the proximal surface and intended to co-operate with pads of loops and hooks sewn and/or stuck to the outer surface of the flexible container opposite the said first pads, the resulting device, when assembled, preventing the valve from rotating on itself when a drain pipe and/or fill pipe is screwed to or unscrewed from the valve.

Abstract: The invention relates to a bag for transporting and handling liquid or quasi liquid substances, that comprises at least a bottom and four sides and optionally a lid. The bag is provided with a sealed inner envelope including filling and optionally draining members. The bag also includes reinforcement plates integrated in the sides and the lid of the bag and optionally in the bottom of the bag. The bag is further provided with members for lifting same.

Abstract: The invention relates to a protective device (10) for a drainage valve (27) fitted to bags or “bags in boxes” intended for the transport and handling of liquid or quasi-liquid substances, said device (10) being formed by a sheet (1) of flexible material folded in on itself, two parallel side edges of said sheet being fixed to one another over at least a part of their length so as to form an approximately rectangular envelope which is open on one of its sides, called the insertion side, into which a reinforcing panel (30) located on the side of the bag and provided with the drainage valve (27) is inserted, said panel (30) having a thickness e1 and being provided with a hole (T) for said drainage valve (27) to pass through.

Abstract: The invention relates to a method for temporarily increasing the resistance to vertical compression of a bag for transporting and holding liquids and quasi-liquids, intended for a bag having the general shape of a cube and including receptacles of each of the corners thereof. The method consists in choosing four inflatable cushioning pouches for each bag, said pouches being elongate and having length, width and extension dimensions corresponding to the length, width and internal volume of the receptacles in the bag. Next, the four cushioning pouches are introduced into the four receptacles and are subsequently inflated, thereby trapping same in a vertical position in which they can resist compression along the vertical axis thereof. The resulting bag is characterized in that the receptacles in the four corners of the bag are each provided internally with a cushioning pouch which is optionally rigidly secured to the bag.
