Tamper-evident closures for application to containers are disclosed. The closures include a cylindrical side wall, a series of frangible bridges, and an annular skirt, and the skirt includes on its inner wall an upper raised portion, a lower raised portion, and an indented central portion therebetween. In this manner, an annular collar on the container can be locked between these upper and lower raised portions on the annular skirt portion of the closure, and this can result in improved consistent fracture of the frangible bridges upon removal of the closure from the container.
