Bottle cap having a latch ring portion that is formed with reinforcing ribs

摘要

A bottle cap includes a cover body adapted to be sleeved on a neck of a bottle, a latch ring portion having a lower peripheral margin with a plurality of integral retaining fins extending upwardly and inwardly therefrom, and a plurality of frangible tabs for interconnecting integrally the cover body and the latch ring portion. The retaining fins have upper ends adapted to be disposed under the flange of the bottle so as to prevent removal of the cap from the neck of the bottle. Each retaining fin has a pair of inclined inner and outer side surfaces, one of which is formed with a plurality of integral reinforcing ribs that are spaced apart from one another along the circumferential direction of the latch ring portion.
