Abstract: An earplug dispensing mechanism defining a longitudinal axis, and including separator and index assemblies. The separator assembly includes a platform, a guide wall and bores. The guide wall projects from the platform to define a well for receiving earplugs. The bores each extend from an entrance opening to an exit opening. The index assembly is rotatably coupled to the separator assembly, and includes a handle, a plate, and a mixing body. The plate is connected to the handle and defines a dispensing aperture. The mixing body has an upper end, a lower end, and an exterior surface defined by a cone portion and a paddle portion. The cone portion tapers in diameter. The paddle portion projects radially from the cone portion at the lower end. The exterior surface is asymmetrical to encourage earplug mixing within the well, and to impede earplugs from entering a bore open to the dispensing aperture.

Abstract: An earplug dispensing mechanism defining a longitudinal axis, and including a separator assembly and an index assembly. The separator assembly includes a platform, a guide wall and bores. The guide wall projects from the platform to define a well for receiving earplugs from a container. Each bore is open to the well at an entrance opening. The guide wall forms a close, compound curve shape in a plane perpendicular to the longitudinal axis and surrounding the entrance openings. The index assembly is rotatably coupled to the separator assembly, and includes a handle, a plate, and a mixing body. The plate is connected to the handle and defines a dispensing aperture. The mixing body is connected to the plate opposite the handle. Rotation of the handle selectively aligns the dispensing aperture with individual ones of the bores, with the guide wall shape funneling earplugs in the well toward the bores.
