Child-resistant package with tamper indicating device
Abstract:
A child-resistant package with a snap-on closure comprising a container having a neck finish including an annular retaining bead having at least one notch therein and a closure having a top and a peripheral skirt. The skirt has a lifting tab on the outer surface thereof and a first radially inwardly extending locking lug on the inner surface thereof adjacent the external lifting tab. A cover cap having a top wall and a peripheral wall is placed over the closure and the peripheral wall of the cover surrounds the peripheral skirt of the closure. An annular band is connected to the lower edge of the peripheral wall of the cover cap by weakened portions. The band includes a plurality of circumferentially spaced radially inwardly extending lugs that project beneath the free edge of the peripheral skirt of the closure so that the cover cap cannot be removed until the band is first removed by severing it from the closure cap. The band normally obscures the view of the indicia on the container that indicates proper alignment of the lug on the closure with the notch on the container. The cover cap normally obscures the view of the construction and indicia on the closure.
