DEFINITION

Classification: 222/478

(under the class definition) Dispensers having (1) two or more openings at least one of which is a dispensing outlet, or (2) two or more separate discharge guides, or (3) a combination between (1) and (2).

(1) Note. Provided that there is one dispensing outlet, the additional openings may be for filling, venting or other nondispensing purpose.

(2) Note. Pattern type openings formed in either the container wall an interior guide or baffle or in a flow controller, are treated as a single opening; see subclasses 564 and 565 and the notes thereto.

(3) Note. Plural openings may comprise (1) containers having two or more separate openings through the walls thereof, at least two of which are for purposes other than the mere passage of actuating elements, mounting or connecting means for movable dispenser parts, (2) containers having a single opening thereinto and a discharge controller having plural openings (one or all of which may be pattern type) so related to the container opening as to permit flow through the controller openings alternatively, (3) containers having a single opening, and a discharge controller having a single opening (which may be of pattern type) so mounted as to present its opening over the container opening or to uncover the container opening (this type usually having a third position in which the container opening is closed with

the flow controller opening out of register therewith).

(4) Note. In subclasses following 478+ are a container having a single opening (other than openings for the mere passage of actuating elements, mounting or connecting means for movable dispenser parts) and a discharge controller having a single opening (including pattern type) the discharge controller being movable from outlet closing position to a position to cause its opening to partially or wholly register with the container opening.

(5) Note. In the subclasses following 478+ are dispensers having a single discharge opening with movable elements associated therewith (as movable discharge guides, closures, valves, or other flow controllers, etc.) and actuating, mounting, or connecting means for such movable elements, in which the actuating, mounting, or connecting means may pass through the container walls through openings formed for such purposes. Where structure or relations are claimed by means of which the actuator mounting or connecting means or its opening also function as vents or for any purpose in addition to permitting passage of the actuating, mounting, or connecting means, classification is in this (478) or the indented subclasses. SEE OR SEARCH THIS CLASS, SUBCLASS:

42, for indicator combinations to indicate which of plural outlets are selected for operation.

69, for float controlled vents.

85+, for cutter combinations which cut plural openings in a container whose contents are to be dispensed.

129+, for combinations of two or more dispensers.

188, for fluid-trap-seal for outlets and vents.

189.01, 189.02+, and 189.06+, for dispensers having porous and/or foraminous material for outlets and vents, the purpose being the separation of diverse types of material.

249+, for dispensers with a floating piston and plural or alternate discharge.

252+, for dispensers with plural discharge assistants delivering to the same or different outlets.

318, for miscellaneous discharge assistants with material by-pass or return to supply.

330+, for miscellaneous discharge assistant and devices having plural material outlets.

332, for movable trap chambers having a vent passage.

375, for dispensers having a supply delivering to a casing enclosed discharge assistant and having antileak or antisiphon means.

387, for material containers having a follower with means to vent gas from the material side of the follower.

396, and 397, for material containers in which fluid under pressure contacts the material to cause discharge and having fluid pressure limiting means, usually a pressure actuated check valve or manual valve for venting.

397, see reference to 396 above.

425+, and see the notes thereto for trap chambers, which have an inlet connected to a supply and an outlet, 426+, having plural nonserial trap chambers connected to the same supply, 431+, having trap chambers with plural or alternate discharge outlets and 442, trap chambers with vents.

468, for vents in a dispenser receptacle handle.

564, for serial discharge guides, flow restrictors or flow restrictor and discharge guide, none of which are controllable. See (2) Note.

565, see note 2 above.
