Abstract
The present invention is a container dispensing cap closure, which includes a container, a circular base and a pivot cap. The container has a neck, an open top and external threading for affixing a circular base thereto. The circular base has a circular inside wall with internal threading for attachment to the neck of the container. The circular base has an inwardly flexible leveraged sidewall trigger with a catch thereon which, when flexed inwardly, engages and pivots a pivot cap upwardly into an open position. The circular base has an upwardly extending guide-wall that regulates the pivotal rotation of the pivot cap, and an opening from which contents may be dispensed. The pivot cap is attached to the circular base by a clasp-element which is attached to two raised sidewall tracts located on the top of the circular base. The raised sidewall tracts comprise impressions which interact with snap-in-bead protrusions located on the clasp-element, thus allowing the pivot cap to pivot thereabout. The snap-in-bead protrusions and impressions are in frictional contact thus stabilizing the pivotal rotation of the pivot cap. The pivot cap also has a flat top and a lip which extends downward…
