Abstract
A can end of the easy opening type comprises an end panel having a preformed dispensing opening and a push tab member having an integrally formed rivet for attachment to the end panel. In one embodiment, the end panel includes a peninsular hinge portion having a rivet receiving opening therein such that all deformation during opening is substantially limited to the hinge portion rather than the push-tab member. In another embodiment, an actuator opening is located between the dispensing opening and the rivet receiving opening of the end panel so as to permit a finger engageable protuberance on the push-tab member to extend therethrough.

A can end of the easy opening type comprising:
- an end panel having a preformed dispensing opening therein and a rivet receiving opening;
- and
- a tab adapated to be pushed inwardly including a rivet extending through said rivet receiving opening to the exterior side of said end panel, said tab including a closure portion closing said dispensing opening on the interior side of said end panel.
A can end of the easy-opening type comprising:
- an end panel having a preformed dispensing opening and a separate opening spaced therefrom;
- and
- a tab closing said dispensing opening and adapted to be pushed inwardly so as to open said dispensing opening, said tab including a fastening portion extending through said separate opening which fastening portion is rigidly attached to said end panel before and after said tab is pushed inwardly.
A can end of the easy opening type comprising:
- an end panel having a dispensing opening therein and a rivet receiving opening, said end panel including a peninsular hinge portion extending into said dispensing opening and having said rivet receiving opening in said peninsular hinge portion;
- and
- a tab attached to said hinge portion and sealingly covering said dispensing opening, said tab adapted to be pushed inwardly as to bend said hinge portion of said end panel during opening.
A can end of the easy opening type comprising:
- an end panel having a dispensing opening located between the center and the periphery of said end panel;
- and
- a tab attached to said end panel including a closure portion, an actuating portion and a fastening portion, said closure portion covering said dispensing opening, said actuating portion protruding outwardly so as to readily permit finger engagement, and said fastening portion being rigidly attached to said end panel, said actuating portion being more centrally located on said end panel than the center of said closure portion of said dispensing opening and said fastening portion being more centrally located than said actuating portion.
A can end of the easy opening type comprising:
- an end panel having a dispensing opening and an actuating opening;
- and
- a tab attached to said panel including a closure portion, an actuating portion and a fastening portion, said closure portion covering said dispensing opening and said actuating portion extending outwardly through said actuating opening so as to readily permit finger engagement, said fastening portion being rigidly attached to said end panel.
A can end of the easy opening type comprising:
- a metallic end panel having a preformed dispensing opening;
- and
- a tab closing said dispensing opening and adapted to be pushed inwardly so as to open said dispensing opening, said tab including a fastening portion extending to the exterior side of said end panel and rigidly fastened thereto for securing said tab to said end panel when said tab is pushed inwardly while exposing the edge of said end panel at said dispensing opening.
