ABSTRACT:
A child-resistent, moisture-tight safety closure having an end wall with an annular depending skirt, the skirt having a plurality of locking lugs disposed on the inside thereof. The locking lugs cooperate with retaining notches adjacent to the open mouth of an associated container to releasably retain the closure on the container. A sealing plug integral with the end wall of the closure and concentric with the annular skirt effects a moisture-tight seal with the inner wall of the container. A plurality of resilient members are integral with the interior of the closure at the junction of the top wall and the skirt, the resilient members extending downwardly and inwardly so as to engage the end surface of the container opening. The compression of the resilient members serves to bias the locking lugs on the closure into locking relationship with the retaining notches on the container with a force sufficient to ensure the child-resistant characteristics of the closure.
