ABSTRACT:
A tamper-evident squeeze-and-turn child-resistant closure includes separate inner and outer caps each of integral monolithic plastic composition. The inner cap comprises a skirt with internal threads having application and removal lugs extending radially outwardly therefrom. The outer cap comprises an outer skirt having application lugs extending radially inwardly therefrom for engagement with the application lugs on the inner skirt to thread the closure onto a container. A pair of diametrically opposed tabs on the outer skirt have inwardly extending removal lugs for engagement with the removal lugs on the inner skirt to unthread the closure from the container. The tabs are resiliently joined at one end to the skirt, and are joined to the skirt at an opposing end by frangible links that rupture upon first inward movement of the tabs to indicate possible tampering with the closure.
