Patent number: 7431168Abstract: The present development is for a closure which provides a liner for abutting a surface and maintaining an effective pressure against a peelable seal affixed to a container lip as the sealed container is exposed to relatively high temperature and pressure conditions. The liner which abuts a surface of the seal sandwiches the seal between the liner and the container lip. The liner defines a resting thickness at ambient temperature and pressure conditions and is made from a material capable of being compressed to a thickness less than the resting thickness and of recovering to a recovery thickness sufficient to allow the liner to maintain a positive pressure against the seal upon exposure to elevated temperatures, elevated pressure, or a combination of elevated temperature and elevated pressure.Type: GrantFiled: December 21, 2001Date of Patent: October 7, 2008Assignee: Rexam Medical Packaging Inc.Inventors: Clayton L. Robinson, Douglas M. Williams, Randall K. Julian, Gary V. Montgomery

Patent number: 7198162Abstract: A molded closure having an auxiliary thread for removal of an incomplete closure from a molding cavity, the molded closure including a helical auxiliary thread projecting inwardly from a cylindrical wall portion of the closure to provide engagement between the closure and the molding core, so that the closure may be threadably removed from the molding cavity by threadably disengaging the molding core from the molding cavity after an incomplete run of the fabrication process. A molding assembly with which the auxiliary thread may be formed in a molded closure is also provided.Type: GrantFiled: June 27, 2003Date of Patent: April 3, 2007Assignee: Rexam Medical Packaging Inc.Inventors: James A.

Patent number: 7168581Abstract: The present development is for a closure which provides a means for maintaining an effective pressure against a peelable seal affixed to a container lip as the sealed container is exposed to relatively high temperature and pressure conditions. The closure includes a liner which abuts a surface of the seal so as to sandwich the seal between the liner and the container lip. The resilient liner and inner foil seal are positioned above a retaining structure and function such that the peelable seal will not rotate relative to a container rim upon engaging the container rim as the closure is rotationally applied. This functions to inhibit torque transmission from the closure to the inner seal or reseal structure and further inhibits imperfections in the container rim from scraping or otherwise damaging the inner seal.Type: GrantFiled: July 28, 2003Date of Patent: January 30, 2007Assignee: Rexam Medical Packaging Inc.Inventors: Clayton L. Robinson, Gary V. Montgomery

Patent number: RE39727Abstract: A dispenser closure is provided having a stopping mechanism that limits the rotation of the closure and generally prevents removal of the closure cap from the container. The dispenser closure includes a cap body, fitment and container finish. The cap body has a double shell design, which includes at least one drop lug projecting from the inner shell. When the cap body is rotated about the container finish, the drop lug engages at least one lug stop located on the container finish so as to limit the rotation, thereby preventing removal of the cap body from the container finish.Type: GrantFiled: December 17, 2003Date of Patent: July 17, 2007Assignee: Rexam Medical Packaging Inc.Inventors: William D.

Patent number: RE38399Abstract: A child resistant cap including relatively thin threads which, when the cap is in a relaxed condition, are spaced from the bottle neck, said spacing permitting the cap to be squeezed inward at points on opposite sides of the cap so that the cap responds to the squeezing by expanding outward at points ninety degrees from the squeezing points so that stops on the cap at the cap expanding location will miss the stops normally engaged when in a relaxed condition, thereby permitting the cap to be removed from the bottle. The cap may also include a guide ring in the cap interior to guide the cap over the bottle neck to help ensure that the cap is centered on the bottle opening. The cap may include pressure pads on the cap skirt outside near the cap bottom showing the user where to press and stiffening the portion of the cap where pressure is to be applied. And, the cap may include a tamper indicating ring which will separate from the cap the first time the cap is removed from the bottle.Type: GrantFiled: July 15, 2002Date of Patent: January 27, 2004Assignee: Rexam Medical Packaging Inc.Inventor: Gary V.
