  • Apparatus for spin bonding ends for composite containers
    Patent number: 4411726
    Abstract: A composite container is disclosed having a synthetic plastic end closure member spin-bonded to the thermoplastic synthetic plastic inner liner layer of a composite container body wall. The synthetic plastic end closure member includes annular downwardly depending inner fin and outer chime portions which are concentrically spaced to define therebetween an annular groove. One of the body and end members is rotated relative to the other member when they are in spaced vertical alignment, whereupon the members are axially displaced together to wedge the upper end of the body member into the annular groove of the end closure member. During this spin bonding process, the fin portion of the end closure member is supported against radial inward deflection, whereby the spinning frictional engagement between the fin portion of the end closure member and the inner liner layer of the body member causes softening and subsequent bonding of the fin portion to the inner liner layer.
    Type: Grant
    Filed: May 6, 1982
    Date of Patent: October 25, 1983
    Assignee: Boise Cascade Corporation
    Inventors: Stephen E. Woerz, Travis K. Canup
