  • Packaging can and method and apparatus for its manufacture
    Patent number: 8746488
    Abstract: A can for packaging food, comprising a metal can body and a diaphragm lid (16) formed of lidding material which comprises a multilayer structure with at least an aluminum layer of from 6 to 90 microns thickness and a bond layer for fixing the lid (16) directly to the can body. One method for forming the can forms the lidding material by using an outwardly extending curl (20) at one end of the metal can body as the draw die. Lidding material which is carried by the body maker punch is drawn around the curl of the can body draw die so as to form the lidding material into a cup shape.

  • Easily openable can lid having a movable portion for pull tab access
    Patent number: 8733576
    Abstract: A can lid of a can provided with an easily openable opening means is disclosed wherein the can lid is equipped with a can lid which is fastened by winding tightly on the can main body and the top end opening of the can main body, a score section installed around the territory of the prearranged opening area and a tab for severing the score section. In the can lid, there is formed a protrusion protruding upward from the can lid in front of the can opening during manufacturing of the can lid, in which it is a collapsing protrusion where the protrusion elastically deforms into the can main body by depressing motion of the user and thereby enables forming of a concave section for easy insertion of the user's finger.

  • Beverage container lid with mouth opening and separate push in vent
    Patent number: 8678221
    Abstract: A container lid includes a conventional main or pour opening and a vent opening spaced from the main opening. A vent score defines the shape of the vent opening, and a vent panel covers the vent opening. The vent panel has a raised convex shape. The lower surface of the tab handle includes a protruding portion, seen as a concave shaped element when viewed from above the container lid. The protruding portion of the tab handle can be aligned with the vent panel so application of a downward force on the tab handle transfers force to the vent panel and breaks the vent score. The shapes of the vent panel and concave element of the tab handle can be adjusted for selective and controlled force transfer to create the vent opening.

  • HIGH SPEED NECKING CONFIGURATION
    Publication number: 20140060137
    Abstract: A horizontal can necking machine assembly includes a plural of main turrets and a plural of transfer starwheels. Each main turret includes a main turret shaft, a main gear mounted on the main turret shaft, a pusher assembly, and a die capable of necking a can body upon actuation of the turret shaft. Each transfer starwheel includes a transfer shaft and a transfer gear mounted on the transfer shaft. The main gears are engaged with the transfer gears such that lines through the main gear center and the centers of opposing transfer gears form an included angle of less than 170 degrees, thereby increasing the angular range available for necking the can body. The main turrets and transfer starwheels may operate to neck and move at least 2800 cans per minute, and each pusher assembly may have a stroke length relative to the die that is at least 1.5 inches.

  • APPARATUS FOR HOLDING A CONTAINER
    Publication number: 20140008856
    Abstract: The apparatus comprises holder (20) with a seating face on which a container such as a cupshaped article (1) stands. Air is supplied through channels and air pressure is balanced so as to hold the article (1) against the face. The profile of the apparatus guides a base feature, or “stand” of the article (1) into the holder (20) and onto the seating face (23), and contacts the article (1) radially outside the seating face (23). The apparatus also has a concentric outer sleeve (25) to provide the additional radial contact and resist lateral movement of the article (1) while maintaining concentricity.

  • Can End
    Publication number: 20130306658
    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.
