Publication number: 20110036840Abstract: The present innovation is a dual purpose “ring-pull/can cap”, which performs as both a sealing cap for metal beverage cans in addition to its traditional usage as a can opener. The design is a modification of the U.S. Pat. No. 3,967,752 “easy open wall”, which is the current opening mechanism on most consumer beverage cans, also known in the industry as an “easy open end”. The “ring-pull/can cap” is an improvement of the well known ring-pull design found on most metal cans today, but also allows consumers to close and seal off the can when not in use. There are two popular opening methods that have been used for opening metal cans to date: The “full open” mechanism and the more recent “half open” mechanism, as described below. The present invention deals with the improvement of the popular “half open” method, which currently does not allow the beverage can to be resealed after opening.Type: ApplicationFiled: August 14, 2009Publication date: February 17, 2011Inventor: Tal Zakai

Patent number: 5741105Abstract: 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.Type: GrantFiled: January 31, 1997Date of Patent: April 21, 1998Assignee: Dayton Systems Group, Inc.Inventors: James R.
