Patent number: 6382441Abstract: 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.Type: GrantFiled: March 22, 2000Date of Patent: May 7, 2002Assignee: Becton, Dickinson and CompanyInventor: Donald J.

Patent number: 6371318Abstract: 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.Type: GrantFiled: December 24, 1997Date of Patent: April 16, 2002Assignee: Owens-Illinois Closure Inc.Inventor: David B. Riffer

Patent number: 6350503Abstract: 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.Type: GrantFiled: February 18, 2000Date of Patent: February 26, 2002Assignee: Static Control Components, Inc.Inventors: Mark D. Cheatham, Donald Albert Pennington, Brian Wayne Holz

Publication number: 20020018901Abstract: A flexible and elastic puncture proof material is provided. The puncture proof material includes a layered stack of a plurality of patterned sheets. Each of the plurality of patterned sheets is cut from a first material in a first shape and has first multiple line cuts through the first material. An edge is around the first shape. Each patterned sheet of the first material has second multiple cuts through the edge of the patterned sheets to provide for elasticity and stability of the edges of the patterned sheet. The first multiple cuts do not connect to the second multiple cuts.Type: ApplicationFiled: August 7, 2001Publication date: February 14, 2002Inventor: Frank W. Cunningham

Patent number: 6322862Abstract: 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.Type: GrantFiled: April 17, 2000Date of Patent: November 27, 2001Assignee: Doppel Co., Ltd.Inventor: Tsuyoshi Sakai
