  • Can end
    Patent number: 8157119
    Abstract: A can end having a countersink bead, an inclined chuck wall and a strong seam, resists distortion from its circular profile when subjected to thermal processing or when packaging carbonated beverages. This high hoop strength affects the manner in which the can end ultimately fails when placed under extreme abuse conditions, even if buckle pressure performance is within industry specified standards. The can end of the invention has control features introduced which control the failure mode whilst maintaining specified buckle pressure performance. In one embodiment, the can end has a two part wall and a control feature that comprises expansion of the countersink bead to act as a trigger for local peaking, together with a groove in the chuck wall which prevents the peaking force from being concentrated at a single point which could result in leaking by the production of a pin hole.

  • CLOSURE ASSEMBLY
    Publication number: 20120074157
    Abstract: A closure assembly comprising a two-part closure having a metal panel or disc (2) and a ring (3), and a container such as a glass jar (20). The ring (3) is substantially cylindrical with an axially upwardly extending sidewall and has a radially inwardly extending lower edge. The jar (20) terminates in a radially outwardly extending beaded rim (16) and the disc (2) has a curled circumference (8) such that this curl (8) co-operates with the beaded rim (16) of the container to provide a primary seal. In one example, in a metal ring (3), the lower edge is curled with equally spaced lugs (13) on the skirt wall. In a plastic ring, the upper rim feature may be omitted.

  • DEVICE FOR AN AXIAL LOAD GAUGE
    Publication number: 20120060620
    Abstract: The invention relates to a device for investigating the statistical variability of an axial load gauge. The device is inserted into an axial load gauge and a load is gradually applied. At a preset load, a mechanism within the device controllably collapses and the applied load is safely transmitted through the structure of the device. A comparison of the load measured on the device load cell against that measured on the gauge load cell facilitates calculation of the repeatability and reproducibility of the axial load gauge. The test is non-destructible and highly repeatable; it permits comparison of load measurements made on different axial load gauge types and in different factories.
