ABSTRACT:
A captive dispensing cap construction for a container, comprising a body part having a discharge passage, and a stopper extending upwardly from the passage. A screw cap part is carried by the body part and has a discharge opening into which the stopper extends when the screw cap part is screwed to its full-on position. The screw cap part and body part have two pairs of mutually engageable portions, one comprising cooperable screw threads for moving the screw cap part axially on the body part as the cap part is turned, and the other comprising a cam track on the body part and a follower portion on the screw cap part. The screw threads have sufficient backlash to enable the screw cap part to have an initial unscrewing turning movement from its fully screwed-on position through an angle essentially in excess of 20.degree. before axial outward displacement of the cap part occurs. The initial rotation without axial displacement operates to loosen previously crusted product from the screw cap part, since the stopper tends to retain part of the crusted product during such initial rotation. Thereafter, the axial movement of the cap forcibly loosens such crusted product from both the screw cap part and the stopper.
