  • Patent number: 8899091
    Abstract: A method of production for a 2-piece “Combo” style closure (1?), having a disk (10?) constrained within a peripheral ring (20?). The “combo” style closure (1?) is produced from a conventional one-piece closure shell (1) by cutting the sidewall (20) in the vicinity of the top plate (10) to produce the ring (20?) and disc (10?) respectively.
    Type: Grant

  • Publication number: 20090032535
    Abstract: A container (1) particularly for food products comprising a metal can body (2) and a combination of a ring (12) and a foil membrane (14), the combination being attached to the can body, in which the ring is made of a plastics material, wherein the inside diameter of the plastic ring is no less than the inside diameter of the can body away from the attachment location of the ring on the can body.

  • Publication number: 20070186613
    Abstract: An assembly for can manufacture includes a toolpack having coolant dies (3,4,5,6) adjacent and either side of ironing dies (1,2) so that coolant may be circulated around cavities in the coolant dies so as to cool the ironing die inserts (12). Generally, the toolpack is used in conjunction with a ram (20), coolant tube assembly (30) and ram guidance assembly (60) which together ensure that the ram is cooled along its entire length, up to and including the punch nose (21).

  • Publication number: 20070102434
    Abstract: A reclosable metal container in the style of a bottle-shaped can has a conventional can body of steel or aluminum to which a metal neck component is seamed. A sleeve of plastics fits over the neck component and a detent inside the sleeve clips it onto the seam. The upper edge of the sleeve is fixed in place by a curl on the upper edge of the neck component. By using a separate neck component and hiding the seam under a sleeve, conventional sizes and material gauges can be used for the can body. Thicker material may be used for the neck component in order to withstand necking forces. Threads for closing the container may be provided either on the sleeve or, in an embodiment where the sleeve is simply used to cover the seam, on a cylindrical part of the neck component itself.

  • Publication number: 20050160743
    Abstract: A self-heating or self-cooling container, which uses a chemical reaction to effect heating or cooling. The reagents for the chemical reaction are stored separately in two sealed compartments (5, 6) having a common dividing wall (7), which can move within the compartments to expand the volume of one compartment at the expense of the other compartment. This arrangement allows efficient use of space within the reaction module of the can, which is particularly important where large amounts of reagent are required to obtain the necessary heating or cooling effect and where the products of the chemical reaction occupy a significantly increased volume compared to the initial reagent in the compartment.

  • Publication number: 20050155599
    Abstract: This invention relates to a self-heating or self-cooling container (1), which uses an exothermic or endothermic re-action to provide or remove heat from the contents of the container. The chemical reaction includes a fluid consistuent (either as a reagent or solvent), held in a reservoir (6), which is added to another reagent in the reaction chamber (5) to initiate the reaction. The container (1) according to the invention proposes a means (8, 91) to control the volume of this fluid constituent added to the reaction chamber (5) depending on the ambient temperature of the container.
