Patent number: 3984025Abstract: An improved pull tab mounting arrangement for an easy open end closure member, characterized by the provision of improved pull tab positioning means for maintaining the pull tab in a desired orientation relative to the panel-defining score line and minimizing tab protrusion from the end closure member. A pierced hole forming a protrusion with a jagged edge is incorporated in the tab nose portion between the free extremity of the tab and the rivet means that secures the tab to the end panel member. The jagged protruding edge of the protrusion is driven into the end panel member during the staking operation, thereby providing an anti-rotation interlock between the tab and the end panel which prevents rotation of the tab nose relative to the score line. The protrusion further serves to raise the nose portion of the tab relative to the end panel thereby biasing the tab against the end panel upon staking of the rivet which forces the finger grip portion of the tab into close contact with the end panel.Type: GrantFiled: November 18, 1974Date of Patent: October 5, 1976Assignee: Continental Can Company, Inc.Inventor: Nick S. Khoury

Patent number: 3970023Abstract: An improved tooling configuration enables production of an end panel opening score line without loss of the enamel protective coating on the reverse side of the end panel. Current scoring methods frequently result in enamel loss, and hence, necessitate coating repair before the end panel may be attached to the can body. By controlling the angular relationship of the score punch and anvil, while simultaneously confining the displaced metal, the enamel which was previously applied to the panel is retained substantially in place with only a slight reduction in thickness. Punch angles of 90.degree. - 100.degree. and anvil angles of 25.degree. - 35.degree. have been found to be effective, with a punch angle of 90.degree. and an anvil angle of 30.degree. being optimum. The metal may best be confined and controlled by the simultaneous formation of an anti-fracture score concentric with, and radially inward of the opening score line.Type: GrantFiled: April 25, 1975Date of Patent: July 20, 1976Assignee: Continental Can Company, Inc.Inventors: Edward J.

Patent number: 3968905Abstract: Timed release of measured quantities of an aerosol spray is accomplished by attachment of an improved dispenser to a conventional aerosol container. The contents of the container are controllably passed through a porous sintered plug and a flow restricting orifice into a measuring chamber in the body of the dispenser. The exit passage of this chamber is sealed by a spring disk which is concave upward with its periphery seated against a shoulder encircling the exit orifice. As the container contents enter the chamber, the pressure therein rises until it is sufficient to overcome the spring resistance of the disk. When this occurs, the disk snaps into its stressed condition, assuming a concave downward shape. It is then supported on projections formed on the exit orifice shoulder. These projections retain the stressed disk in spaced relation to the exit orifice and allow a quantity of the chamber contents to pass around the disk and escape through a nozzle mounted on the exit orifice.Type: GrantFiled: August 7, 1975Date of Patent: July 13, 1976Assignee: Continental Can Company, Inc.Inventor: Peter G. Pelton
