Abstract

There is described a bag (100) for the transport and storage of bulk goods comprising at least a bottom part (15) and four sides (11-14) connected in pairs along adjacent edges to form vertical ridges at four corners of the bag (100). The bag (100) further comprises four lifting straps (18) provided in an upper portion of the bag (100) along the vertical ridges of the bag (100), which lifting straps (18) are interconnected in pairs by two sleeves (17) to form tubings or ducts extending along an upper longitudinal end of two opposite sides (12, 14) of the bag (100) to allow lifting of the bag by means of a forklift. Slits (20) are further provided on an upper side of each sleeve (17), at both ends of each sleeve (17), next to the lifting straps (18), thus forming four anchor points around the lifting straps (18) to allow lifting of the bag (100) by means of a four-point lifting device.

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, comprising the steps of: - providing a tubular fabric; - flattening said tubular fabric to form a first double-thickness fabric having two opposite sides, respectively an internal side (11a) and an external side (11b), extending between two flattened edges (12, 14); - folding-in or pleating at lest one of the flattened edges (12, 14) of said double-thickness fabric (10) to form a gusset (20); - cutting said tubular fabric into pieces and assembling said pieces to form a bag; wherein the assembly of two said pieces (10, 10') comprises the steps of: - assembling the first and second pieces (10, 10') by means of seams (23) formed around or near first to fourth gusset ends (15, 19, 15', 19').

Abstract

Bag having at least one of its sides (2, 3) 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 invention relates to a method for improving the filling of a liner, as well as a container formed using said method and comprising a longitudinally folded liner, said container being characterised in that the bottom quarter of the inner surface of one of its vertical walls is provided either directly or indirectly with at least one strap that can be temporarily closed. Moreover, a strap surrounds the liner, and the portion of the liner located below the strap extends horizontally towards the centre of the container over at least one third of the width of the container.

Abstract

The device for the stabilisation of drain and/or fill valves for a flexible container intended for the transportation of liquids or pulverulent materials is characterised in that it comprises the use of a valve that is not strictly cylindrical, said valve comprising at least one of the following three members: a lug (2'), in a low position, formed by the downward extension of a through valve key (2); a proximal polygonal flange (4'); or a partially polygonal protrusion (8). The device is also characterised in that a stabilisation plate (9) includes both a recess (12) which matches and hugs the contour of the above-mentioned selected member and two pads of hook and loop fasteners (17, 18) adhered to the proximal face and intended to engage with pads of hook and loop fasteners (15, 16) which are sewn and/or adhered to the outer surface of the flexible container such as to face the aforementioned first pads. The device thus formed and assembled prevents the valve from rotating on itself when a drain and/or fill pipe is screwed to or unscrewed from the valve.

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 at 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 characterised 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.
