Abstract: A method and apparatus for extrusion coating both sides of a metal strip. A metal strip, such as aluminum alloy strip, is moved through a pre-conditioner, two extrusion dies, a post-heater and a cooling system. Both sides of the strip are coated with thin coatings of thermoplastic polymers. The coated metal strip is useful for containers, such as cans and can ends, as well as for automobiles, appliances, aerospace, construction and electrical devices.

Abstract: A method for extrusion coating both sides of a metal strip. A metal strip, such as aluminum alloy strip, is moved through a pre-conditioner, two extrusion dies, a post heater and a cooling system. Both sides of the strip are coated with thin coatings of polyester material. The coated metal strip is useful for containers, such as cans and can ends, as well as for automobiles, appliances, aerospace, construction and electrical devices.

Abstract: A dual-purpose one-piece plastic closure for surgical irrigation fluid containers. The closure may be removed from the neck of the container when liquid is to be dispensed by pouring or, alternatively, may be pierced by and sealingly coupled to the connector spike of an irrigation set when liquid is to be drained from the container for closed system irrigation. The closure includes a port sleeve which has a primary seaing zone at a level slightly below the closure's top wall. The disclosed embodiment also includes a secondary sealing zone between the primary zone and the dome-shaped bottom wall of the port sleeve. The connector spike, its construction, and its cooperative relationship with the closure, are also disclosed.

Abstract: A thermoplastic bottle for sterile medical liquids with a dispensing outlet closed off by an inner closure. An outer closure in the form of a thermoplastic cap overlies the inner closure. During steam sterilization at 240.degree. to 260.degree. F (116.degree. to 127.degree. C) the outer cap deflects inwardly against the inner cap to force the inner cap into a tighter seal against the bottle. This outer cap includes external left-handed threads and has a lateral frangible brim fused to the thermoplastic bottle. A threaded jacking ring is screwed onto the outer cap and with a counterclockwise motion acts to (1) fracture the cap's external brim and (2) separate the outer cap from the sealed inner cap.

Abstract: A container for sterile medical liquids that has a double cap sealed closure system. A deformable thermoplastic top wall of an outer cap is spaced a distance from a top wall of an inner cap when properly sterilized. Thumb pressure on the outer cap brings the top walls of the two caps into contact. This contact provides an instant tactile test for determining that the container has been through a steam sterilization cycle and there are no leaks at the inner and outer cap seals with the bottle.

Abstract: A sterile medical liquid container system that includes an inner cap and an outer cap nested together and having interconnecting splines. The inner cap has internal right-handed threads and is screwed onto a threaded bottle neck to hermetically seal this neck. The outer cap has external left-handed threads and is fused at a frangible joint to the thermoplastic bottle. A jacking ring with internal left-handed threads screws onto the outer cap and a continuous clockwise motion of the jacking ring acts to (1) fracture the outer cap, and (2) unscrew the combined intersplined inner and outer caps from the container neck.
