Abstract: An induction heat-sealed closure liner assembly having a restricted product orifice that is smaller than the mouth of the container to which the assembly is attached, to allow restricted dispensing of product through the orifice. The closure assembly is designed for storing and dispensing a product, such as a solid, liquid or paste product, and includes primary and secondary liner components that are positionable within a retainer portion of a cap to form the closure liner assembly.

Abstract: A venting cap liner has a bottom surface facing an annular bottle lip surrounding an open top end of a bottle neck, and a top surface facing an inner top wall of a closure cap, the liner being configured to provide a gas-permeable but liquid-impervious seal that is resistant to rupture when a downwardly directed torque is applied in a thickness direction of the liner body to compression seal the liner body between the annular bottle lip and the inner top wall of the cap.

Abstract: Non-removable closure assembly that resists rotational movement so as to be rendered substantially non-removable by the consumer. An induction heat seal liner is provided for sealing the finish (open end or mouth) of a plastic container, the liner being disposed between a closure cap and the container finish and being heat seal bonded to both, thus rendering the closure cap non-removable from the container finish. By non-removable it is meant that once heat seal bonded together the closure cap cannot be removed by a customer or consumer (a human) by hand, without substantially distorting the closure cap or container, e.g., it would require the human to use a mechanical tool (e.g., knife or wrench) and in the process of trying to remove the cap with the tool it would substantially deform the closure cap or container and render one or more of them unusable for their intended purpose.

Abstract: Method of fabricating a polymeric tube for attachment to a prefabricated tubular polymer body comprising: selecting an ethylene copolymer functionalized with a conjugated vinyl moiety, and coextruding an outer tubular layer comprised of the selected functionalized ethylene copolymer together with at least one inner tubular layer comprised of a thermoplastic elastomeric material to form a mating tube having an outer surface comprised of the functionalized ethylene copolymer, a central tubular passage having a longitudinal axis and opposing ends.

Abstract: Molded article for medical tubing and the like, and method of manufacture. The molded article is a coextruded tube having a tube wall of a non-conductive thermoplastic polymer and a central tubular bore. The tube further includes a coextruded conductive strip of conductive fibers in a thermoplastic polymer matrix, the conductive strip being disposed within a tubular passage in the tube wall extending the length of the tube, or within the central tubular bore. The strip is made from a pultruded fiber/polymer compound that can be co-extruded in strip form in the tube to provide an electrically conductive path along the tube length. Advantages include ease of manufacture, and one or more of improved handling (during use), reduced profile and reduced material costs.
