DEFINITION

Classification: 222/544

(under the class definition) Dispensers having a flow controller or closure for the discharge outlet.

(.5) Note. Outlet arrangements which operate to vary the flow of material though not capable of cutting it off entirely are included.

(1) Note. The preceding subclasses having such devices with the specific additional characteristics there provided for. The following (not exhaustive) are specially mentioned).

SEE OR SEARCH THIS CLASS, SUBCLASS:

14+, for cutoffs operable by selectively preset volume or rate of flow responsive mechanism.

23+, for recorders, register, indicator signal or alarm combinations. 52+, for automatic control combinations.

70, for combinations involving timing mechanism.

76, for electrical controls.

92+, for combinations with collapsible wall receptacles where characteristics of the collapsible wall are claimed or other features are claimed which are present because of the collapsible wall. Where the collapsible wall is merely claimed by name, the patent is classified with the subcombination specifically recited.

110, for drip, leakage, or waste catching or disposal including a valved return to the main supply.

153.01+, for lock or fastening seal combinations.

162, for movably mounted supply receptacles which move relative to a discharge controlling valve.

187, for wick or absorbent material feed for dispensing devices in which the wick or absorbent material controls the discharge.

196.1+, for hand manipulable shaker type dispensers having outlet elements which may have impact on the container or contents, especially subclass 196.4, for those having an element caged in the outlet, which element is a ball acting as a closure when the shaker is at rest.

212+, for resilient wall dispensers with flow controllers or closures.

226+, for flow controllers interconnected with an agitator.

310+, for flow controllers associated with discharge assistants to vary discharge volume. 354, for relatively movable cutoffs carried by movable trap chambers.

355, for cutoffs, interconnected with movable trap chambers for operation.

380, for valved outlets for casing enclosed discharge assistants which are associated with a material supply chamber.

387, for containers having followers and a valved outlet.

420, for drop forming outlet devices especially 422 for such devices with valves.

425+, for trap chambers having cutoffs where more than the mere outlet with its flow controller and/or closure is

claimed.

469, for movable handles interconnected with flow controllers or closures.

470+, for a handle and actuator for a flow controller or closure juxtaposed for one-handed manipulation.

476, and the subclasses following the same and preceding subclass 544, for flow controllers and closures in the special combinations or of the particular types provided for.

138, Pipes and Tubular Conduits, 40+, for flow restrictors in pipes and tubular conduits.

184, Lubrication,

65+, for gravity 65+ feed lubricators, subclass 69 having a cutoff (usually a ball) that opens due to vibration of the device with which the lubrication is used.

193, Conveyors, Chutes, Skids, Guides, and Ways,

20, 21 for vertically swingable valved chutes.

220, Receptacles,

200+, closures for recptacles having no dispensing features and see the notes to subclass 200 for the distribution of the closure arts.

221, Article Dispensing,

289+, for article dispensing devices having closure or other means to effect mechanical release or separation of articles.

251, Valves and Valve Actuation,

142+, for flow path devices with a single valve, especially subclass 144 for tank mounted valves.
