ABSTRACT:
An apparatus and method is disclosed to facilitate the dispensing of powders, particularly toner in a photocopy machine, which must be vibrated to prevent clumping. A powder container is shown with a unique neck baffle, and sloping sides so that the flow of powder is substantially regular when the vibration is turned on and the flow will stop when the vibration is turned off. A method and apparatus for adjusting the natural frequency of the container system is shown so that the amplitude of vibration does not significantly increase as the dispenser is emptied and the flow of powder is thereby maintained at a relatively constant rate.
