ABSTRACT:
The object of the invention is to provide a container-closure assembly with detent means for positive positioning of the closure with respect to the container at a preselect intermediate position between full closure-container cooperation and non-cooperative relationship.
A neck (16) of a container (10) is provided with external threads (22) including a detent positioning assembly (24) comprised of a pair of outwardly extending projections (26a and 26b) formed on a plane perpendicular to the axis of the container. The closure or cap (30) thereof is formed with internal threads (38) for engaging the external threads (22) of the container (10) and a detent positioning assembly comprised of inwardly extending projections (40) below the internal threads (38) thereof. Threading of the closure or cap (30) on the neck (16) of such a container (10) cause the inwardly extending projections (40) of the closure (30) to contact the initial downwardly extending projections (26a and 26b) provided on the neck (16) of the container (10) necessitating a slightly greater rotational force to be torsionally applied to cause the projection (40) on the closure to override the initial projection (26a ) on the neck of the container thereby to place the projections (40) of the closure (10) intermediate the pair of outwardly extending projections (26a and 26b) on the container (10).
