ABSTRACT:
A child resistant package comprising an open-mouth container having a plurality of circumferentially spaced projections extending radially outwardly adjacent the open end thereof, each projection defines a notch facing downwardly, and a closure having a top panel and an annular skirt depending from the periphery of the top panel, and a plurality of radially inwardly extending and circumferentially spaced locking lugs on the inner surface of the skirt. The locking lugs are adapted to engage the notches in the projections on the container. A tamper-indicating member comprises an annular ring having portions extending between the lower edge of the skirt of the closure and a portion of the container and operable to normally limit axial movement of the closure. The ring offers a visual indication that the contents have not been tampered with and the ring must be removed before the closure can be removed. The container includes a specially designed inclined surface provided with dual slopes. One slope extends radially outwardly in a circumferential direction and the other slope extends downwardly and radially inwardly and terminates in a locking notch. The closure can be applied to the container when the tamper-indicating member is in position through rotation of the closure causing the cam lugs on the closure to engage the inclined surface and flex the skirt of the closure outwardly to thereby direct the cam lugs into engagement with the locking notch.
