Tearable bottle caps

A tearable bottle cap for large capacity bottles comprising a top planar disk, an approximately cylindrical skirt depending from said planar disk to snugly fit around the neck of the bottle, a slant score line starting at the lower edge of said skirt, a pull tab projecting downwardly of said lower edge of the skirt, one of the side edges of the pull tab being arranged to terminate at the point on said lower edge of the skirt where the score line starts, an inner solid bead having an arcuate surface and extending throughout the circumference of said skirt at a predetermined distance from said top disk, in order to engage the lower portion of the upper bead of a bottle neck, a plurality of vertical, radially inwardly directed lugs projecting from the corner between said top disk and said skirt and having a slant lower edge, in order to engage the upper portion of the upper bead of a bottle neck, said lugs being equidistantly provided around the periphery of said disk and having a width such that they will accomodate therebetween the upper terminal portion of a threaded bottle neck, said radially inwardly directed lugs also serving as rigidifying elements for the upper portion of the cap in order to provide a shock absorber when the cap is used with unthreaded neck bottles, and a circumferential internal rib projecting from the inner surface of said top disk, said internal rib being of a diameter such that the upper edge of the terminal portion of a threaded neck bottle will abut thereon, in order to serve as a shock absorber for the upper edge of the bottle neck when the cap is used with threaded neck bottles, said radially inwardly directed lugs serving as rigidifying elements of the upper portion of the cap by abutment on the outer edges on the threads of the terminal portion of the threaded neck bottle, in order to avoid sidewardly directed movements of the cap.
