<p>A closure cap (45) for a container outlet (20) is configured with a child-resistant feature involving a pair of abutment projections (29, 30) formed as part of the container outlet (20) and a pair of abutment ribs (46, 47) formed as part of the closure cap (45). The container outlet (20) includes an annular skirt (27) which provides a support surface for the pair of abutment projections (29, 30). The pair of spaced-apart abutment ribs (46, 47) are designed to ride over each abutment projection (29, 30) during threaded advance of the closure cap (45) onto the container outlet (20). During retrograde rotation of the closure cap (45) onto the container outlet (20), the abutment ribs (46, 47) are designed to abut up against the abutment projections (29, 30). The abutment ribs are manually movable in a radially inward direction for taking each abutment rib out of abutting engagement with a corresponding abutment projection.</p> |
