Abstract
An earplug dispenser is provided which dispenses earplugs directly into a user's hand upon turning of a knob in either a clockwise or counterclockwise direction. The earplug dispenser is designed for quick and efficient replacement of an empty container with a container full of earplugs. The internal delivery components are particularly designed to prevent earplug jamming or sticking and aid in the quick delivery of a desired number of earplugs directly into the user's hand. The design also allows the earplugs to be delivered without relying on a separate opening or port apart from the impeller thereby eliminating the need to use two hands to deliver or dispense the desired earplugs.
