Abstract
A child-resistant safety container for preventing access to the contents by small children and infants includes a positive-on closure concept and necessitates a two-step release procedure in order to remove the cap from the container spout. The closure cap includes an internally threaded side wall with a pair of inwardly protruding lug means. The internally threaded cap is suitably adapted for receipt by an externally threaded container spout. Disposed in combination with the container spout are sawtooth detent means including two series of ratchet teeth which are spaced approximately 180 degrees apart. These ratchet teeth are suitably sized and arranged for interlocking engagement with the inwardly protruding lug means. However, one series of ratchet teeth are offset from the other series by a half ratchet tooth spacing so that the engagement of the locking lugs with the ratchet teeth alternates from one locking lug to the other with each angular turn equal to a half ratchet tooth. The ratchet teeth have an axial height which is sufficient to prevent removal of the cap with one 180-degree turn. In order to remove the cap from the container spout, it is required that the closure cap be distorted into an elliptical shape and two turns of approximately 180 degrees each be performed.
