ABSTRACT:
A dry product dispenser uses vibration to move product into a dispensing location. A piston is mounted in the dispenser to be moved by pressure exerted thereon by propellant, and a spring mounted post prevents contact between the propellant and the product until the piston has moved a predetermined distance. Immediately after contact between the propellant and the product, the piston is returned to a repose position in which such propellant-product contact is prevented. The cycle is repeated rapidly as long as an actuating element on the device is activated. Alternative embodiments include child safety features.
