Abstract
A flexible hopper made of rubber or other suitable flexible material which is driven by a motor through an eccentric drive so as to cause the hopper and a drive auger to vibrate to more readily dispense product in the hopper. One or more flexible fingers are attached to the auger and are flexed as the auger rotates so as to further improve the flow characteristics of the materials in the hopper.
