DEFINITION

Classification: 604/214

Mechanical means (e.g., piston, clamp, etc.) moved to collapse reservoir:

(under subclass 212) Subject matter including a mechanism operated by a person to collapse the material reservoir.

(1) Note. Included in this subclass is a squeeze bulb which forces air in a chamber to compress a resilient material container disposed in the chamber, or a pliers-type clamp for squeezing a resilient material container.
