Abstract
A safety closure and a container is comprised of a container having an externally threaded neck portion and a first locking bead spaced downwardly from the threaded neck portion and a closure having a cap portion and a tamper indicating band portion. The cap portion is provided with a top wall and a side wall which extends downwardly from an outer periphery of the top wall and terminates in a lower end. The side wall is provided with an internal thread which is engageable with the externally threaded neck portion of the closure. The tamper indicating band portion is attached to the lower end of the cap portion with a plurality of frangible bridge segments. The tamper indicating band portion is also provided with an inwardly projecting second bead which is engageable with the first beads whereby the engagement of the bead prevents removal of the tamper indicating band portion upon removal of the cap portion. At least one ramp is integrally formed with the second bead and projects downwardly therefrom. Engagement of the beads prevents removal of the tamper indicating band portion upon removal of the cap portion.
