.~ Intercommunicable reservoirs or reservoir sections in series
DEFINITION
Classification: 401/151
(under subclass 143) Implement including a plurality of reservoirs or means dividing a reservoir into separate zones (e.g., reserve and immediate-use reservoirs or zones) for retaining portions of material out of contact with one another, and force-applying means to cause flow of material from one reservoir or zone to another.
(1) Note. A chamber intended to serve merely as an air space (e.g., squeeze bulb, filler tube), and not to contain coating material, will not be considered a reservoir section for this subclass even though the disclosure may allude to a possible entry of material therein; as by overfilling, for example. A
patent involving such air-space-containing structure will be found in an appropriate subclass indented under subclass 143 (e.g., subclass 185).
SEE OR SEARCH THIS CLASS, SUBCLASS:
40+, for a reservoir having zones or compartments one of which is for retaining soluble coating material and the other for solvent.
44, and indented subclass 45, for plural reservoirs the coating materials from which merge in the feeder or at the tool, but which are otherwise nonintercommunicable.
146+, for an implement including a pump chamber between a feeder and a reservoir and directly contiguous to the feeder. 225+, for a bifurcate point nib implement which includes a compartment, within or adjacent the feeder, for receiving excess material discharge from the reservoir.
230, for an implement having a compartmented reservoir combined with a bifurcate nib pen, which implement has not claimed material-moving force-applying means.
