Abstract

A dispenser for dispensing disposable lids from a coaxial stack of nested lids. The dispenser has a v-shaped tray with an open dispensing end for holding the stack, a resilient member biasing the lids towards the open dispensing end and a pair of spaced apart friction surfaces opposing the tray at the open dispensing end. The friction surfaces are inclined at a low angle to the stack and overhang the tray forming a throat through which the lids pass. As the lids are pushed into the throat by the resilient member biasing the lids, the friction surfaces stop movement of the stack through the throat and an endmost of the lids is unlatched from a next-to-endmost lid opposite the friction surfaces. A curved finger followed by a stop is reciprocated between the friction surfaces. When the finger is reciprocated towards the stack of lids, it makes contact with the endmost flange, overriding and hooking under its flange. The finger is stopped between the endmost lid and the next-to-endmost lid by the stop pressing against the endmost lid. When the finger is then reciprocated away from the stack of lids, the endmost lid is separated from the next-to-endmost lid and kept on the finger by the…
