DEFINITION

Classification: 222/206

(under the class definition) Dispensers having one or more walls or portions thereof which may be distorted or deflected by application of a force, to expel material which wall or

walls return to their original position when the force is removed.

(1) Note. The wall return motion may be due to its own resilience or due to a spring or other biasing means.
