Abstract
280,853. Hammer, C. Nov. 18, 1926, [Convention date]. Cap - stoppers, bayonet - joint ; stoppers, making.- A metal cap for glass containers comprises a top 2, Figs. 2 and 3, and a depending skirt 5 provided with a crescent - shaped closed or tubular lug 8 formed by pressing the bead inwardly at two peripherally spaced points. The radius of curvature of the inner face of the lug is less than that of the beaded edge 7 of the cap and the lug is less compressed between its ends than at the ends. The cap is formed with corrugations 6 and portions of the bead are offset inwardly to form the lugs 8. The upper or thread engaging surface 12 of the lugs is curved or bevelled in cross-section and may be inclined in the direction of its length to correspond to the inclination of the threads on the container. In making the cap, a hat-shaped blank is disposed on a chuck formed with recesses corresponding to the lugs 8 and, after the flange has been pressed radially inward to form the beaded edge 7, the blank is engaged by a punch 20, Fig. 7, having projecting ears separated by a crescent-shaped portion. The resulting lugs are of crescent-shape and of such dimensions as to pass over the neck of the container. The arc formed is smaller than that of the bead 7 which is adapted to pass over the threads on the container neck. Specification 241,809 is referred to.
