Abstract: A tearable bottle cap comprises a top planar disk, an approximately cylindrical skirt depending from said planar disk to snugly fit around the neck of said bottle, a first inner bead extending throughout the circumference of said skirt at a predetermined distance from the lower end of said skirt, to engage the lower portion of the upper bead of the bottle neck, a second inner bead extending throughout the circumference of said skirt at a predetermined distance above said first inner bead, in order to engage the upper portion of the upper bead of the bottle neck, a plurality of vertical, radially inwardly directed lugs projecting from the corner between said disk and said skirt and having their lower ends embedded in said second inner bead to be reinforced thereby, said lugs having a width such that they will accommodate therebetween the upper terminal portion of a screw threaded neck bottle, said radially inwardly directed lugs also serving as shock absorbers when the cap is used on unthreaded neck bottles no

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.
