  • Method of manufacture of a gated can lid with score at upper surface
    Patent number: 4018178
    Abstract: A can lid includes a pushdown gate formed in a panel portion below a narrow, underfolded rim at the opening in the lid. The outline of the gate is a disruptible score cut in the panel portion underneath the rim. This structure is essentially the same as that disclosed in the Klein-Harper U.S. Pat. No. 3,334,775. However, the score cut defining the outline of the gate is at the upper surface of the panel portion instead of being at the undersurface. A method of drawing and folding the lid material permits the score line to be cut before the underfolded rim is formed over the score cut.
