Abstract
Abstract An earplug dispenser to deliver one or two earplugs from a bulk supply which includes a front housing having an access door, a rear housing and a removable cover. Situated inside of the rear housing is a hopper having an opening with a central tab. A chute is located inside the front housing and has a trough which terminates slightly below the lower edge of the access door. A conveyor member, attached to a supporting extrusion member includes a pair of rollers which are journalled one above the other, a belt mounted on the rollers having a series of carriers and a means for rotating the rollers. As the rollers are rotated, the carriers are elevated through the hopper of earplugs picking up an earplug and dispensing it down the chute to the trough. Earplugs are easily removed through the access door.
