Patent number: 7556488Abstract: An apparatus for compression molding sealing liners in premade closure shells includes a shell loader for presenting premade closure shells in sequence, a mold charge placement device for placing charges of liner material into the premade shells, and a vertical wheel molding machine for receiving the closure shells in sequence from the loader and compression molding the mold charges to form sealing liners within the closure shells. The vertical wheel molding machine preferably includes a wheel mounted for rotation around a horizontal axis and a plurality of angularly spaced molds disposed around the wheel. Each of the molds preferably includes a first mold segment and a second mold segment disposed radially outwardly of the first mold segment. One of the first and second mold segments, preferably the second mold segment, includes a nest for receiving a premade closure shell.Type: GrantFiled: June 17, 2005Date of Patent: July 7, 2009Assignee: Rexam Closure Inc.Inventors: Daniel L.

Patent number: 5794803Abstract: A child-resistant closure and dispensing container package in which the measuring cup has a second, exterior annular wall forming threads engageable with threads on the neck of a container and child-resistant lock means at a lower portion of the wall engageable with complementary lock means on the container in a locked position to prevent unthreading of the closure from the container until the annular wall is deflected to move the complementary lock means out of engagement with each other to permit rotation of the closure in an unthreading direction. Also a seal is provided to prevent leakage during unthreading movement of the closure between fully closed and a locked position of the closure.Type: GrantFiled: November 1, 1996Date of Patent: August 18, 1998Assignee: Rexam Closures, Inc.Inventor: William Douglas Sprick

Patent number: 5785196Abstract: The closure cap of a closure and container package for a pressurized liquid is designed with a sealing flange which depends from the cap top at an angle to a sealing location on the container wall so that an increase in container pressure will increase the sealing force of the flange against the container wall. A pressure relief passage is provided downstream of the sealing location.Type: GrantFiled: October 29, 1996Date of Patent: July 28, 1998Assignee: Rexam Closures Inc.Inventor: Gary V. Montgomery

Patent number: 5738231Abstract: A threaded tamper indicating closure-container package provides an indication of initial opening by how far the closure threads onto the container neck. In the original package condition the bottom of the closure skirt is adjacent a shoulder on the container. After the package has been initially opened and the closure reapplied, the bottom of the closure skirt is noticeably above the container shoulder. A word message such as "opened" can also be exposed on the container neck between the shoulder and the bottom of the closure skirt when the closure is reapplied.Type: GrantFiled: April 19, 1996Date of Patent: April 14, 1998Assignee: Rexam Closures, Inc.Inventor: Gary V.

Patent number: 5722547Abstract: Tamper indicating closure and container assembly which prior opening of the assembly is indicated by exposing projections formed integrally with the closure with such projections remaining concealed in the originally closed position of the assembly. In one embodiment the tamper indicating features are associated with the label on the container and in another embodiment of the invention the tamper indicating features are associated with a pouring spout on a gable-top container.Type: GrantFiled: September 20, 1996Date of Patent: March 3, 1998Assignee: Rexam Closures Inc.Inventor: William J. Shankland

Patent number: 5722546Abstract: A child-resistant closure and container package having push tabs formed in the closure to prevent rotation relative to the container until the push tabs are deflected radially inwardly to disengage from lock members on the container to permit unthreading rotation of the closure relative to the container. Simultaneous squeezing of the push tabs and rotation of the closure permit removal of the closure from the container. Also, a tamper indicating feature is associated with the push tabs.Type: GrantFiled: December 13, 1996Date of Patent: March 3, 1998Assignee: Rexam Closures Inc.Inventor: Marc Briere

Patent number: 5692628Abstract: A closure-container package is illustrated in which the closure is pressed-on to the container neck and threaded off the container neck. Either the container neck or the closure has a helical thread which engages axially extending ribs on the other of the container neck or closure to form indentations in the ribs which act as threads, teeth or a track for unthreading. A continuous or rotary seal is used between the container neck and the closure which does not require a sealing force from the threaded connection.Type: GrantFiled: January 11, 1996Date of Patent: December 2, 1997Assignee: Rexam Closure, Inc.Inventors: Gary V. Montgomery, James F. Whitehead, Clas Nilstoft

Patent number: 5690241Abstract: A removal resistant closure cap for a container having a standard threaded neck is disclosed. The cap does not have a thread complementary to the container neck thread but has an inwardly projecting circumferential bead with an intersecting projection extending downwardly from the bead at the helix angle of the container neck thread. When the container neck is engaged by the cap with a threading rotation, the cap projection will engage the container neck thread, and the cap bead will snap over the container neck thread, permanently retaining in the cap on the container neck.Type: GrantFiled: September 18, 1996Date of Patent: November 25, 1997Assignee: Rexam Closures, Inc.Inventor: Gary V. Montgomery
