Patent CA-2306084-A1 (CA)
Title: Tamper-indicating closure and method of manufacture
Inventor: WEBSTER CHARLES A
IPC: B65D41/34
Filed: 2000-04-18
Abstract: A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with an internal thread for affixing the closure to the container finish. A tamper-indicating band is connected to an edge of the skirt by frangible bridges. A stop flange extends from an edge of the band remote from the skirt for abutment with a bead on the container finish to inhibit removal of the closure absent fracture of the frangible means. A plurality of circumferentially spaced openings extend radially through the skirt at a position between the frangible bridges and the internal thread. These openings provide for ingress of cleansing solution during a washing operation after the closure is applied to a container to flush any residue from between the tamper-indicating band and the closure finish. Drain openings are provided in the stop flange and/or the tamper-indicating band to allow drainage of the flushing solution, and also to allow drainage of any accumulated liquid in wet-finish applications.

Patent CA-2318005-A1 (CA)
Inventor: PORTMANN HEINZ
IPC: F17C1/06
Filed: 2000-09-12
Abstract: The invention relates to a process for the manufacture of reinforced-reinforced pressure vessels and the product produced therefrom. A ductile metal vessel liner, being formed with at least one nozzle, is wrapped with a first composite layer of resin-impregnated fibers. Pressure is applied to the vessel sufficient to yield the liner but is insufficient to cause deformation of the nozzle. The liner retains a residual compressive stress critical for withstanding cyclical service pressures. A second composite layer is applied over the first layer to increase the strength of the vessel sufficient to maintain the vessel's integrity at very high cyclical service pressures (such as about 0 - 10,000 psig). The vessel is then pressure tested at 1.5 times the intended service pressure to ensure vessel integrity.
