    摘要: A tab for use with an easy-open can end, which is made free from any protrusion with a cut edge thereon that would otherwise contact a finger or a lip of the user without a increasing the number of manufacturing steps to complete the tab. A tab having a body, a nose end with a tip, an opposite grip end, and an island formed within the tab body and attached to the nose end along a hinge, the island including a rivet hole for receiving a rivet on a can end panel to attach the tab to the end panel. The tab body is joined to a carrier strip, from which the tabs are made, by a joint formed in a tab making process. In a tab severing process, the joint is cut off to sever the tab from the strip, leaving a protrusion on the tab with a cut edge. The tip of the nose has a gap into which the protrusion can be bent or curled, to guard the cut edge, as the tab is moved to attach the island to the end panel with a rivet. When the tab is lowered in the downward passage, the swing arm moves to cause the curling surface to press the tab and curl the protrusion onto the tab.

    摘要: The invention, relating to an easy-open metal container end, places a portion of the metal of the tear panel, in the region where a score stop otherwise would be located, under compression by forming a short coined depression or bead in the tear panel, preferably in the public side, close to the score line at least at the end of the vent region opposite from the inner hook, which is located at the radially inward end of the tear panel score line. During initial opening or venting action, as the rivet is lifted by initial tab motion, separation proceeds along the score line, beneath the nose of the tab. The metal adjacent and in this coined depression tends to move partially underneath the metal on the opposite side of the score line from the coined vent bead. This action provides sufficient disruption or retarding of the score line separation or rupture, during venting, to confine such separation to the vent region until internal pressure is vented. Further separation of the tear panel can proceed under control of continued raising tab motion and resulting opening force. By providing such a coined vent bead, the score stop may be made considerable less deep leaving adequate residual metal along score line 15, or the score stop can be entirely eliminated in some cases, thereby making it possible to achieve consistent and proper venting in ends made of thinner metals, e.g. in the order of 0.009-0.008 inch.

    摘要: The invention, relating to an easy-open metal container end, places a portion of the metal of the tear panel (12), in the region where a score stop otherwise would be located, under compression by forming a short coined depression or bead (40) in the tear panel, preferably in the public side, close to the score line (15) at least at the end of the vent region (35) opposite from the inner hook (16), which is located at the radially inward end of the tear panel score line. During initial opening or venting action, as the rivet (25) is lifted by initial tab motion, separation proceeds along the score line, beneath the nose (28) of the tab (27). The metal adjacent and in this coined depression tends to move partially underneath the metal on the opposite side of the score line from the coined vent bead. This action provides sufficient disruption or retarding of the score line separation or rupture, during venting, to confine such separation to the vent region until internal pressure is vented. Further separation of the tear panel can proceed under control of continued raising tab motion and resulting opening force. By providing such a coined vent bead, the score stop may be made considerable less deep leaving adequate residual metal along score line (15), or the score stop can be entirely eliminated in some cases, thereby making it possible to achieve consistent and proper venting in ends made of thinner metals, e.g. in the order of 0.009-0.008 inch.

    摘要: An easy opening container wall comprising a container wall of sheet material having a line of weakness therein defining a tear portion at least partially removable from the container wall. Removal of the tear portion provides a relatively sharp edge along the tear portion. A guard is provided along the periphery of the tear portion to protect the consumer from injury. The guard is interrupted adjacent the location at which the line of score is initially ruptured to facilitate such initial rupture. The outer periphery of the guard and the score line are configured and positioned relative to each other to minimize interference by the guard during the opening operation.

    摘要: The transfer conveyor system utilizes at least one endless conveyor belt of reinforced flexible rubber-like material with cogs or teeth on its underside and with a series of nests fitted into holes in the belt. Nests for carrying can end shells are attached at their opposite edges to the belt. The belt is supported by and routed around an idler drum, located outside the press frame posts and by a toothed drive drum located within the press frame adjacent the opposite frame posts. Progressive conversion tooling for making shells into completed easy-open can ends is located between the posts above and below upper and lower tooling sets. The drive drum is provided with circumferential teeth for a positive drive to the belt. Attachments of nests to the belt are located on transverse center lines which permit the flat nests to travel around the end turns of the belts. Shells are positively seated into the nests and held by a circular array of independent flexible stepped fingers as the nests are transferred through the conversion tooling. Completed ends are carried around the drum at the end of the upper flight, and the ends are ejected from the nest rings and moved [as by force from air streams] along a table or chutes. These chutes receive the ends from the lower or return flight of the conveyor, providing a compact (end-to-end) conveying system.

    摘要: The transfer nest for an endless conveyor belt of reinforced flexible rubber-like material, optionally with cogs or teeth on its underside, a series of such nests fitted into holes in the belt. The nests are attached to the belt solely at their opposite edges on lines extending transverse to the belt. The belt with attached nests, having end shells trapped therein, is moved stepwise through progressive conversion tooling for making shells into completed can ends. Shells are positively seated into the nests by moving the shells through a discontinuous entrance rim, preferably defined by the upper parts of a circular array of independent flexible stepped (preferably L-shaped) fingers which support the shells which are each trapped in a nest as the nests are transferred through the conversion tooling. Completed ends may be carried around the end of the conveyor upper flight, and the ends can be ejected from the nests.

    摘要: A method and an apparatus are provided for manufacturing a tab for use with an easy-open can end, which tab is free from any exposed protrusion or cut edge thereon that would otherwise contact a finger or a lip of the user, without an increase in the number of manufacturing steps. A tab, attached to a carrier strip by a joint, is formed in a tab forming process, and the tab is severed from the strip in a joint severing process wherein the joint is cut off close to the tab nose to separate the tab from the strip. The tab with a protrusion which has a cut edge, remaining on the tab nose, is lowered while being held against horizontal movement. The protrusion is brought into engagement with a curling surface of an arm which is supported to swing in a downward passage through which the tab descends. When the tab is lowered in the downward passage, the arm is swung to cause the curling surface to press against the tab and curl the protrusion onto the tab.
