  • Patent number: 5749496
    Abstract: The present invention is a semi-flexible captive cap closure which includes a non-removable cap that rotates between a closed and open position and has opposing squeeze points that must be biased inwardly in order to open the cap. The preferred embodiment of the present invention includes a container which has a base and a neck for retaining the cap. The neck has at least one inclined recess track which has at least one impression which is adequately sized to correspond to a protrusion located on the cap. When the cap is in a closed position a user grasps the cap at the opposing squeeze points and applies inward pressure in order to displace the protrusion from the impression and to allow rotation to an open position. The cap is maintained in an open position either by frictional contact between the track and protrusion or by a second corresponding impression.

  • Patent number: 5551607
    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.
