Anti-jam dispenser

摘要

Embodiments of the disclosure include earplug dispensers that may comprise a rotating cam assembly operable to dispense one or more earplug to a user when a knob is rotated by the user. In some embodiments, the cam assembly may comprise and upper cam layer and a lower cam layer attached via clips to the rotating knob. Upon rotation of the knob, the upper cam layer may cause the earplugs to fall through one or more cavities to the lower cam layer. The lower cam layer may comprise a pushing structure operable to move the earplugs, upon rotation of the knob, within the lower cam layer to fall down through an opening in the dispenser. In some embodiments, the earplugs may fall through an opening in the rotating knob.

主权项

1. An earplug dispenser comprising:
a dispenser bottle operable to hold a plurality of earplugs; and a rotatable cam assembly attached to the dispenser bottle, operable to dispense the earplugs from the dispenser bottle, the rotatable cam assembly comprising:
an upper cam layer comprising one or more cavities, wherein each of the one or more cavities is configured to accept a single earplug from the dispenser bottle and pass the single earplug to a lower cam layer that is disposed below the upper cam layer;the lower cam layer comprising a pushing structure; anda rotatable knob at least partially defining an opening that is disposed below the upper cam layer and the lower cam layer, wherein the rotatable knob is attached to the lower cam layer and the lower cam layer is attached to the upper cam layer such that rotation of the rotatable knob causes each of the lower cam layer and the upper cam layer to rotate,wherein the earplug dispenser is configured such that rotation of the rotatable knob over a first angular distance causes an earplug of the plurality of earplugs to fall through one of the one or more cavities of the upper cam layer to the lower cam layer, andwherein the earplug dispenser is further configured such that rotation of the rotatable knob over a second angular distance causes the pushing structure to displace the earplug that fell from the upper cam layer to the lower cam layer radially inward toward the center of the lower cam layer and toward the opening through which the earplug can fall.
