Abstract: An easy open ecology end consisting of a removable section defined in an end panel and a tab for severing the removable section is disclosed herein. The removable section or disc is defined by a weakened score line and the tab has an opening edge aligned with at least a part of the inner edge of the score line with the opening edge having primary contact means for producing initial rupture of the score line. The tab is attached to the end using a unique method which will produce internal stresses in the metal of the tab so that the tab is constantly urged toward the surface of the end. The tab also has an opening therein aligned with the removable section and is designed to be locked into the opening created by severing the weakened line.

Abstract: A can having a closure defined at least in part by a rupturable weakening line is provided with a finger-movable tab-like tool for safely opening the closure. The tool is a sheet metal lever pivotally attached to a can end in which the closure is deflectible and preferably non-severable. A depressor portion of the lever is raised from its prone or inoperative position and, in part, twisted about 90.degree. to locate its pressure-directing beak adjacent to a point along the weakening line, whereupon downward finger pressure on the depressor portion disrupts the line and deflects the closure inwardly. The lever is so shaped that depression of the twistable portion is limited by engagement therewith of an edge of the opening thus barring finger entry into the can opening as a safety measure. The lever may be provided at its opposite end with a handle whereby, when the closure has been opened as explained, the lever may be swung to clear the depressed end portion substantially from the can opening.

Abstract: An easy open ecology end is disclosed herein and includes an end panel that has a removable section defined by a weakened score line. A tab is secured to the removable section and the tab and removable section are designed so that both remain captive with respect to the end panel when the weakened score line is severed. The weakened score line is produced by a unique three step process and has an area of reduced residual which is first severed when a force is applied to the tab so that the container is vented before the remainder of the residual is severed. The tab is designed to produce a localized initial pressure to initially sever the area of reduced residual and then sever the remainder of the score line.

Abstract: Easy-opening container wall structure having a non-removable and selectively separable openable member to which is attached an opening tab member. A portion of the opening tab member can be manually displaced outwardly from the container wall, thereby forcing another portion of the opening tab member against the container wall to initiate separation of the openable member. The opening tab member thereafter transmits inwardly-directed manual pressure to complete separation of the openable member, and to retain the opening tab member from unrestricted movement into the container. The periphery of the separated openable member co-acts with the periphery of the opening in the container wall to retain the separated openable member on the container.

Abstract: An easy-open container having a wall in which an openable member is defined by a selectably separable region. A separate opening tab member is secured to the openable member to receive manual opening force and fracture the separable region. A flange on the opening tab member overlies at least part of the separable region to prevent the opening tab member and the attached openable member from freely entering the container. The openable member is nondetachably retained on the container by the configuration of the separated openable member, or by a pivotable connection between the opening tab member and the container.

Abstract: An end structure for an easy open container includes an end wall and a panel defined by a score line. Fold portions, which support the panel in a plane different from the end wall, form an annular shoulder around the score line. A guard ring having portions defining a manually actuatable punch is rotatable on the shoulder between a first position wherein the punch has a distal relationship with the score line and a second position wherein the punch has a proximal relationship with the score line. The guard ring can be set to the first position to inhibit opening of the container and can be moved to the second position to facilitate opening of the container. With the rupturing of the score line and displacement of the panel to open the container, the guard ring displaces slightly to guard the sharp free edge of the ruptured score line and thereby to inhibit lacerations of the user's finger.
