ABSTRACT:
A container having a tubular neck and a cup-shaped cap, the container and cap having twist action retaining means such as cooperating threads, in which the container and the cap also have child-resistant locking means. The child-resistant locking means consist of at least one set of co-operating stop and lug, preferably two each. When the cap is turned onto the neck to closed position, that one of the stop or lug on the cap is turned clockwise beyond engagement. The stop has a lug engaging abutment face which is inclined backwardly from its outer edge in a counterclockwise direction. When the cap is turned in retrograde direction toward opening, and the lug engages the abutment face it is urged radially inwardly to more strongly resist unscrewing the cap. The stop and lug are disengageable by radially outwardly deforming the portion of the cap on which one of the stop or lug is formed.
