Abstract
A manually operable dispenser for dispensing disposable earplugs. The dispenser includes a housing, an index body, and a plate. The housing forms an opening for receiving earplugs from a container. The index body includes a handle and a hub. The hub forms an upper major face, a lower major face, and a plurality of circumferentially arranged bores. Each of the bores is open to the major faces and is defined by a wall surface extending through a thickness of the hub. At least a portion of the wall surface of each of the bores has an anti-bonding construction. The hub is rotatably mounted within the housing. The plate is connected to the housing, and forms a dispensing aperture. A manually-applied rotational force at the handle selectively aligns respective ones of the bores with the dispensing aperture. The anti-bonding construction promotes sliding, low friction interface with individual earplugs.
