    Abstract: A container bag i.e. a flexible intermediate bulk container or FIBC (10) comprising a body of flexible material having lifting loops (18) across the corners thereof and baffles (22) to maintain a square configuration is characterized in that a liner (28) is provided sealed to the baffles (22). In accordance with the present invention baffles (22) are positioned within the liner (28) and are sealed to it before the liner (28) is affixed to the FIBC. In this manner, an FIBC can be produced which has both baffles giving it a square configuration and a liner to prevent ingress of moisture and air. The liner taking on the "square" configuration imparts it to the FIBC as a whole. The baffles may protrude from the liner and be attached to the FIBC walls, or they may be wholly within the liner. In either case, the liner (28) will preferably be impervious to air and moisture and may be formed from a polyolefin sheet material.

A check valve for air infusion, which is used for filling air in the air bag, is mounted in one of the air chambers. When air is infused into a space between either of a pair of sheets and the releasing layer through an air infusion port of the check valve, the releasing layer and the corresponding sheet are peeled from each other by the air pressure. As a result, the air chambers are formed between the two layers.

    Abstract: A synthetic plastic bag for containing liquids, e.g., urine, has a plastic outlet tube. It is manufactured by a first step of seam welding the tube between two superposed bag walls. In a subsequent step, an encircling sleeve is slide over the tube to a position where it contains within it the portions of the bag walls on either side of the tube. Thirdly, this sleeve is compressed onto the tube by a crimping operation conducted with the crimping force applied in a direction radially of the tube but at substantially right angles to the plane in which the bag walls lie. Alternatively, after the tube is seam welded between the bag walls, the bag and tube combination is then placed between the blocks of a mold, each block having confronting recesses of a particular shape and molten plastics material is injected to fill these recesses. The injected material forms a collar which completely surrounds the tube.

The rear wall of the bag is however provided with a tranversal window made of transparent, flexible plastic sheet material, extending over the width of the bag and comprising a plurality of perforations distributed over its surface. The transparent plastic sheet material is thicker than the opaque plastic sheet material; it requires additional mechanical resistance due to the perforations. A method and apparatus fabricate the plastic bag from two strips of opaque plastic sheet material, and a strip of transparent plastic sheet material.

  • Patent number: 5222812
    Abstract: A bulk container of flexible fabric having a substantially rectangular base and four walls with four corners at the junctions of the walls has four interior bridging panels extending between adjacent walls across the corners, the bridging panels each being formed of fabric which is integral with part of said adjacent walls. In one embodiment, the four bridging panels and the four wall centre panels are formed of a single main piece of fabric, and the corners are formed by corner pieces attached to the main piece of fabric at the junctions between the bridging panels and the wall centre panels. The corner pieces each comprise a folded strip of fabric which forms a lifting device. Holes are cut through the bridging panels by laying the main piece of fabric in doubled condition and cutting two layers in one operation. The container has a pyramid shaped top cover with a central filing chute, and an outlet chute.

  • Patent number: 5205650
    Abstract: Orientable thermoplastic polymeric film material is provided with at least one stretched zone in which the material has been stretched in a first direction and, adjacent to the opposite sides of the zone, unstretched zones in which the material is substantially unstretched. The material is of particular value for preventing rupture of bags containing the material, especially when the zones are adjacent a seam in a filled sack and/or in the gusset of a gusset bag.

  • Patent number: 5181610
    Abstract: A pouch for the packaging of products having a pressure sensitive adhesive thereon, such as sanitary napkins. The pouch is formed of paper of plastic film coated on one side with a layer of silicone, the pouch construction being such that the silicone coating defines the interior surfaces of the pouch. Due to the nonstick characteristic of the silicone coating, the usual protective liner for the adhesive on the packaged product can be omitted. The side seams of the pouch are formed by the application of heat or ultrasonic energy in combination with mechanical deformation of the paper or film to produce embossments in the seam areas. The side seams may be comprised of two or three layers of material. The nature of these side seams may be such that the pouch may be opened by peeling apart the seams, or the seams may be sealed so tightly that the pouch can be opened only by tearing the material.

  • Patent number: 5139346
    Abstract: In a flexible container, there is provided three or more approximately rectangular main sheets, and a rectangular inlet sheet and outlet sheet are provided on an imaginary line passing through approximately the central part in the width direction of each of the main sheets. One end of each of the inlet sheet and the outlet sheet in the direction along the imaginary line is sewed to an end of the main sheet corresponding to the one end, and the other end of each of the inlet sheet and the outlet sheet is projected away from the main sheet in the direction along the imaginary line. The imaginary lines of assembly sheets each constituted by the three types of sheets conform to one another, opposed surfaces of the adjacent assembly sheets are joined to each other, and outer side edges of the adjacent assembly sheets are sewed together.

  • Patent number: 5104236
    Abstract: A reinforced collapsible bag and method of making it from blanks of a flexible woven material which are cut from an elongate web substantially without wasting any material between adjacent blanks with pairs of reinforced strips extending along the side edges and through the central portion of the sides and top and bottom of the bag, thereby reinforcing the bottom, top, sides and corners of the bag. Each blank has a circumferentially continuous central portion and four isosceles triangular portions at each end of the blank. Adjacent sides of adjacent triangular portons are connected together to provide, when the bag is exapnded or filled, generally square ends which are interconnected by generally rectangular side walls. Lifting sstraps can be attached to the reinforced strips along the side edges of the bag. An access opening is provided in an end of the bag by terminating the connections of its triangular portions short of their apexes.

  • Patent number: 5078509
    Abstract: A resealable package for snack food items and a method of making the same from a sheet of flexible material. Two side edges of the sheet are joined together in a seam, with a flap extending longitudinally from an exterior surface of the package. A resealable adhesive is disposed beneath the flap, whereby the flap serves as a release strip to protect the adhesive until use. The consumer re-closes the package by removing the release strip to expose the adhesive. The package then is folded downward a number of times until the exterior surface of the package is secured to the adhesive.

  • Patent number: RE34477
    Abstract: This invention, Infections/Medical Waste Containment Carrier, is a manufactured, flexable container in which solid and/or liquid infectious/medical waste is placed for containment, storage, transport and incineration. The Infectious/Medical Waste Containment Carrier consists of three integral functional components:1. A coextruded polyethylene tube with walls of a given thickness.2. A closure pouch with a self-contained tie cord.3. A bottom seal of dual thermo-sealed bars with enforced cross members and air pockets.Once the bottom seal is applied to the coextruded polyethylene tube the tube becomes a bottom closed container. When the pouch is applied at a specific position located in the center and near the top of the container carrier and the bottom and top are serrated, the containment carrier is constructed to serve as a depository for infectious/medical waste.
