Abstract
Abstract A mechanism for dispensing container closures, one at a time, from a stacked array. A hand operated slide bar is positioned at the bottom of the closure stack. An upturned edge or finger is attached to the slide bar, thus enabling it to engage with the inside rim area of the closure and pull the closure from the stack. The finger on the slide bar is beveled so that it will slide beneath the container rim when the slide is returned to its inward position.

Claim 1
Independent Claim
295 words
A dispenser for a flexible disk shaped closure with an attached rim, including an elongate cylindrically shaped closure storing chamber for storing a vertically oriented stack of closures, a bottom plate positioned adjacent one end of said storing chamber and attached thereto, a slide bar retaining plate positioned next to and in juxtaposed relationship with respect to said bottom plate, an elongated slot, formed with reentrant corners, positioned along a diameter of said slide bar retaining plate, a slide bar positioned and guided for movement within said slot, said movement being limited by engagement of said slide bar with said reentrant corners, a closure engagement foot attached to and positioned intermediate the ends of said slide bar, an upturned edge on said closure engagement foot cantilevered at an angle with respect to said slide bar for engaging the inside rim of a closure, a cover plate containing a slotlike aperture for surrounding a portion of said closure engagement foot, said cover plate positioned adjacent to and above said slide bar, a circumferentially positioned aperture in said storing chamber wall opposite said slot in said slide bar retaining plate, a notch formed in a bottom edge of said aperture for providing specific ingress and egress for said slide bar and its closure engagement foot, said slide bar passing through and movable within said notch so that when said slide bar is moved from an inward to an outward position a closure will be partially withdrawn from said dispenser through said aperture and when said slide bar is moved from an outward to an inward position said cantilevered upturned edge will cam beneath the rim of a closure positioned within said storing chamber and assume a position whereby the next closure can be extracted from said dispenser.
