Abstract: A file-index card system for retaining and displaying conventional business cards is disclosed. The system includes a frame in which is held a multiplicity of file cards in the form of planar sheets. Each file card has an area of adhesive covering a portion thereof, with a protective peel-off covering placed over the area of adhesive. Registration markings are provided on each file card to at least one side of the area of adhesive, the registration markings serving to delimit the edge of a conventional business card to be affixed to the file card. In use, the protective peel-off covering is removed to expose the adhesive. A conventional business card is then aligned with the registration markings and is affixed to the file card to thereby be displayed.

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.
