    Abstract: A barrier gasket (20, 120, 220, 320, 420, 520) uses two different materials to seal between components (22, 24). The first relatively inexpensive material (30, 130, 230, 330, 430, 530) is used for the base material and a second material (40, 140, 240, 340, 440, 540) is used to form the seal that contacts the fluid. The second material (40, 140, 240, 340, 440, 540) is compatible with and chemically resistant to the fluid with which it will come into contact. The second material (40, 140, 240, 340, 440, 540) forms a protective barrier that prevents the fluid from coming in contact with the first material (30, 130, 230, 330, 430, 530).

  • Patent number: 6399170
    Abstract: A plastic closure that includes a cap having a base with a peripheral skirt defining a cap interior and threads on the skirt for securing the closure to a container. A liner is secured to the interior of the cap, preferably by compression molding in situ. The liner consists essentially of a blend of a matrix polymer, a particulate barrier polymer and an compatibilizer. The heat and pressure of compression forms the particles of barrier polymer into platelets that are oriented essentially parallel to the plane of the disk.

  • Patent number: 6382441
    Abstract: A closure assembly is provided that includes an outer cap with a skirt dimensioned to telescope over the open top end of the tube. An annular shoulder extends inwardly from the top end of the skirt and includes an aperture through which a needle may be directed. A laminated seal is bonded to the bottom surface of the annular shoulder of the outer cap and extends continuously across the aperture in the annular shoulder. A stopper is secured on the bottom surface of the annular seal and is dimensioned for sealing engagement in the open top of the tube. Outer circumferential portions of the bottom surface of the laminated seal between the skirt and the stopper are bonded to the open top end of the tube. The bond between the closure and the laminated seal is stronger than the bond between the tube and the laminated seal. Thus, the closure assembly retains its structural integrity after opening of the tube and can be used to reseal the tube.

  • Patent number: 6371318
    Abstract: A plastic closure that comprises a cap having a base with a peripheral skirt defining the cap interior and threads on the skirt for securing the closure to a container. A liner is secured to the interior of the cap, preferably by being compression molded in situ on the base. The liner consists essentially of a multiplicity of alternating layers of a matrix polymer material such as EVA and a barrier material such as EVOH to resist transmission of gas, water vapor and/or flavorants through the liner. The matrix polymer material preferably is preblended with a compatibilizer material such as a maleic anhydride grafted polymer that ties the matrix polymer material to the barrier material.

  • Patent number: 6350503
    Abstract: A Toner Cartridge Seal Assembly including a gasket, a handle integral with a gasket, and a removable seal lying over the gasket. The handle which is integral with the gasket is in, one embodiment, removable by detaching the handle from the remainder of the gasket along a series of perforations. Alternatively, in another embodiment the handle may be folded over the gasket after the seal assembly is attached to the toner cartridge. The Toner Cartridge Seal Assembly of this invention is used to contain toner in a toner hopper during the transport of a toner cartridge. The removable seal is, in the preferred embodiment, integral with a tail. The tail folds back over the seal and extends outside of the cartridge. Upon arrival at its intended destination the end user pulls the tail removing the removable seal and exposing the toner in the toner hopper to the remainder of the toner cartridge. The invention is usable in both new and rebuilt or remanufactured toner cartridges.

  • Patent number: 6322862
    Abstract: An object containing pressed flowers sealed therein which is composed of a base layer, an intermediate layer of molten resin in which is sealed a pressed flower, and a surface layer of transparent film, with these three layers integrally laminated on top of the other, characterized in that the intermediate layer is formed by pressing with heating under reduced pressure from a meltable porous plastic film such that the molten plastic adheres closely to the pressed flower to seal it and also fixes the pressed flower to both the base layer and the surface layer of transparent film. It retains the natural color of the pressed flower for a long period of time without deterioration by air and moisture.
