Filed:

Jan 31, 1997

Appl. No.:

8/792895

Inventors:

James R. Schubert - Dayton OH
John F. Schubert - Dayton OH
Steven T. Cook - Bellbrook OH

Assignee:

Dayton Systems Group, Inc. - Dayton OH

International Classification:

B21D 5300

US Classification:

413 25

Abstract:

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.

Abstract:

A resealable can end is provided including a neck member and hat member which can be sealed onto and removed from the neck member of the end, and is capable of containing product under pressure if desired. This end can be added, as by a conventional seam, to a metal container body to obtain resealing containment of partial contents retained in the container, and to provide an improved mouth construction (or pour opening) for better pouring and for comfortable direct drinking from the container. Also disclosed are improved methods of and apparatus for making such a resealable hat and-neck type-of container end.
