  • Closure insert
    Patent number: 6832692
    Abstract: An insert (1) for a closure provides, in a single component, a gasket function between the end panel (12) of the closure and the end sealing surface (22) of a container neck finish (20), a thread forming feature (3) and a tamper evident band (5). The sealing portion (gasket (2) and thread forming feature (3)) of the insert is formed from soft pliant material so as to provide excellent sealing. The tamper evident band (5) is made from much stiffer material than that of the sealing portion, thereby providing rigidity to the entire component. During assembly the integral tamper evident band (5) thus maintains the insert in a circular and non-twisted shape, ensuring ease of handling of the insert.

  • Coating of articles
    Patent number: 4809640
    Abstract: Plastic containers are given a coating of barrier or other coating material by being passed in close proximity to the lower edge of a plate curved downwardly. Liquid coating material is delivered to the back of the plate, to spread over it and fall as a curtain through which the article is passed, the article being rotated to present the whole of its recipient surface to the curtain. The articles may be tilted as they pass through the curtain.
