DEFINITION

Classification: 222/386

(under subclass 251) Dispensers in which there is an element

acting as a supply container wall which follows the material as it is dispensed.

(1) Note. The follower may be caused to move by atmospheric pressure only, or there may be means associated therewith to cause motion.
