  • Patent number: 4669620
    Abstract: A tamper-evident, child-resistant closure apparatus and method for containers has a three position inner and outer cap assembly. The first position provides a shipment position in which, if the cap is tampered with, a visible indication alerts the user that tapering has occurred. The visible indication is a portion of the inner cap assembly which displaces, upon tampering, a frangibly connected disk member which is attached to the top of the outer cap member. Displacement of the frangibly connected disk member occurs in a second position of the inner and outer cap members, in which a protruding portion of the inner cap member has an interference relationship with the frangibly connected disk. To effect removal of the cap closure assembly, the inner and outer cap members must be moved axially to a third position whereby rotation of the outer cap member transfers sufficient rotational force to the inner cap member to unseat it from its sealing relationship with the container.
