ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to dispenser closures. More particularly, the present invention relates to threadably movable dispenser closures with stopping mechanisms.
2. Discussion of the Prior Art
Dispenser closures that open by the axial movement of a cap along a container finish are generally known in the art. Such a closure commonly includes a cap portion that is threadably attached to the finish of a container in such a way that the cap may be threadably moved from a closed position to an open position so as to access the contents of the container. The cap of this type of closure commonly has a limited range of rotation, so that the cap may remain affixed to the container even while in the open position.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a closure having a dispensing feature.
It is another object of the present invention to provide a double shell dispenser closure having a stopping mechanism which limits the range of rotation of a closure cap about a container finish.
More particularly, the apparatus of the present invention includes a double shell closure having a dispensing mechanism. The dispenser closure includes a cap body that is threadably attached to a container finish and a fitment placed in an aperture of the container and operably disposed between the cap body and the container finish. The container finish includes a neck portion with an opening therein, at least one thread and at least one lug stop thereon. The fitment has a plurality of spokes that connect an annular side wall with a post that is concentrically aligned therein. The cap body includes an inner wall and an outer wall concentrically aligned. In one embodiment, both the inner wall and the outer wall are annular and are concentrically aligned with an opening in a top wall of the cap body. The inner wall may include at least one thread on an inner surface thereof. The inner wall also has at least one drop lug projecting from a lower portion thereof. In one embodiment, two drop lugs are diametrically aligned and project downwardly from the terminating edge of the annular inner wall. The drop lugs are positioned to engage the lug stops located on the container finish, so as to prevent the threadable removal of the cap body from the container finish. The double shell dispenser closure may be partially opened to allow dispensing of the contents of the container, but may not be removed from the container due to the stopping mechanism.
