ABSTRACT:
A two-piece child resistant closure is disclosed in which an outer, molded plastic, closure driving member is formed with an indicator portion that is connected thereto with some webs that are frangible and some non-frangible. The inner plastic member is formed with internal threads that engage the container and it has lugs which engage driving lugs of the outer member when the outer member is pushed down a predetermined amount. The inner member has an upstanding plunger that serves to engage the indicator and break the frangible connections upon displacement of the members to place them in driving connection for removal of the inner member from the container.
