  • Patent number: 6697248
    Abstract: The invention teaches improved materials and processes for production of structures to shield against ingress of egress of electromagnetic radiation. The structures and processes taught are based on the recognition and use of directly electroplateable resins. The directly electroplateable resins are combined with electrodeposited metal-based coatings to result in uniquely suitable structures to achieve radiation shielding. Fabrication and compositional flexibility of directly electroplateable resins and low cost material possibilities contribute to the unique suitability of directly electroplateable resins in the production of improved electromagnetic radiation shields.

  • Patent number: 6681947
    Abstract: A bottle cap including a top, a skirt, a locking bead, a tear tab, a line of weakness and a gusset. The top has a perimeter. The skirt depends from the perimeter and has a bottom edge. The locking bead radially extends from the skirt intermediate the top and the bottom edge. The tear tab extends downward from the bottom edge. The line of weakness extends along the skirt upward from the bottom edge and onto the top. The gusset extends from the locking bead into the skirt. The cap allows a user to remove the cap from a bottle in a facile manner.

  • Patent number: 6637611
    Abstract: A tamper-evident, snap-on, screw-off closure is used with a specially shaped container neck. One neck has double lead external threads and, below the threads, a conical wall having external ratchet teeth. The closure has an upper skirt having internal threads mating with the neck threads. A conical lower skirt is connected to the upper skirt by a plurality of frangible bridges. The lower skirt has internal ratchet teeth to mate with the neck ratchet teeth. The cap skirt threads are double pitch and slightly over 360° in length. When the cap is applied to the neck it snaps on in two stages. The lower skirt has a tear tab which, when pulled, fractures the lower skirt on a vertical line. Continued pulling on the tab sequentially fractures the bridges. Another neck has a neck stretch with multiple neck threads and a locking wall below the neck stretch with a plurality of external teeth.

  • Publication number: 20030127414
    Abstract: The neck of a container has a smooth seal surface engaged by the inner skirt or plug of a cap. Such surface is free of trim and parting line flaws which are characteristic of blow-molded jars because the surface is formed in such a way that the seal surface is not in contact with mold parting lines and further the trim (excess plastic) of the neck is located away from the sealing surface. In one form of the disclosure, above the sealing surface the neck wall slants outward and then bends upward-inward in a short, tapered stretch about 18.degree. to the horizontal which engages the underside of the cap disk to compress against the disk or a liner or foil. Other forms of seal surfaces are disclosed In another form of the invention, above the seal surface the neck extends outward and then upward and then inward in a flange which is trimmed along a line which has a circumference no less than the circumference of the seal surface.

  • Publication number: 20020195415
    Abstract: A closure including a cap and a liner. The bottle cap includes a top, a skirt and a liner retaining protrusion. The top has a perimeter and an inside surface. The skirt depends downwardly from the perimeter. The liner retaining protrusion depends downwardly from the inside surface of the top and is adapted to prevent shifting of the liner with respect to the cap. the top, skirt and liner retaining protrusion may be monolithically formed. The liner retaining protrusion may be conical. The liner retaining protrusion may be spike-shaped. Alternatively, the liner retaining protrusion may include a cylindrical wall which depends downwardly from the inside surface of the top. The liner retaining protrusion may include an outwardly extending bead extending from a lower portion of the cylindrical wall. The liner retaining protrusion extends into the liner to retain the liner and prevent the liner from axially shifting with respect to the cap. The liner retaining protrusion may extend into and through the liner.

  • Patent number: 6464096
    Abstract: A fitment for use as a pour spout for a paper carton or flexible bag for liquids and powders has a flange which may be welded around a hole in the carton or bag. A spout projecting outward from the flange is provided with a removable membrane integral with the interior of the spout. Preferably the membrane is concave. A horizontally disposed pull ring is attached to the membrane by a connector so that pulling the ring removes the membrane by fracturing the tear line at the juncture of the outer edge of the membrane and the projection. A cap snaps over the spout and may be removed by unscrewing the complementary threads on cap and spout. Optionally, a tamper-evidencing band frangibly connected to the lower edge of the cap skirt engages the exterior of the spout so that the cap cannot be removed without breaking the frangible connection. Various means for detachably securing the fitment to a spud during delivery of the fitment from a chute to the interior of a carton are disclosed.

  • Patent number: 6459032
    Abstract: This invention comprises deposition of thin film photovoltaic junctions on conductive foil substrates which can be heat treated following deposition in a continuous fashion without deterioration of the metal support structure. In a separate operation, an interconnection substrate structure is produced in a continuous roll-to-roll fashion. The conductive foil supported photovoltaic junction is then laminated to the interconnection substrate structure and conductive connections are deposited to complete the module or array. In this way the interconnection substrate structure can be uniquely formulated from polymer-based materials since it does not have to endure high temperature exposure. Furthermore, the photovoltaic junction and its conductive foil support can be produced in bulk without the need to use the expensive and intricate material removal operations currently taught in the art to achieve series interconnections.
