ABSTRACT:
A tear open bottle cap comprises a top planar disk 2, a cylindrical skirt 1 depending downwardly therefrom, a slant score line 9 extending upwardly from the lower edge of the skirt, a pull tab 7 projecting downwardly from the lower edge of the skirt at the score line, and an inner bead 4 extending around the circumference of the skirt and spaced from the lower end thereof to engage an upper bead of the bottle neck. The score line crosses the inner bead and has severable transverse partition walls 21, 22. A plurality of vertical, radially inwardly directed lugs 6 project from the corner 3 between the disk and skirt and have slant lower edges 11 for engaging the upper bead of the bottle neck. A circumferential internal rib 5 on the disk abuts the upper edge of the bottle neck to act as a shock absorber, together with the lugs 6.
