    Abstract: 1,114,826. Opening containers. ALUMINUM CO. OF AMERICA. 11 Nov., 1965 [25 Nov., 1964], No. 47982/65. Heading B8D. [Also in Division B3] A pull tab 6, Fig. 1, is attached to a tear strip 4 defined by score lines 3 in the metal end wall 2 of a container by means of a hollow rivet formed, Fig. 12, in both the end 2 and the tab. The container body 1 may be of glass, foil and fibre laminate, or plastics, and the tab may be bendable or of the rigid lever type. During the formation of the rivets the metal of the transverse portions 13c, 1 flows sideways to form interlocking heads 18, 19 (see Division B3), the portions 13c, 14c becoming thinner than the upstanding walls of the rivets in the process.

    Abstract: A method and apparatus are provided for stripping container bodies from a reciprocal mandrel in an ironing press at the completion of the ironing stroke, which includes a resilient pad which is positioned adjacent the exit end of the last ironing ring and aligned with the mandrel for abutment of a container body on the mandrel against the pad at the completion of the ironing stroke, and means for introducing compressed gas into the container body being ironed prior to completion of the ironing stroke. The compressed gas in the container will hold the container body against the resilient pad whereby the mandrel may be withdrawn from the container during its return stroke.
