Class 222
DISPENSING
Class Definition:
This is the generic class for processes and apparatus for
dispensing material, and takes all such subject matter that
must be classified on such basis and not provided for in
other main classes.
This class is not limited as to the character of the
materials dispensed which may be in any physical state, i.e.,
it may be in a gas, vapor, liquid, viscous, paste-like or
solid state and if in a self sustaining state may have any
form or shape.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Dispensers are found in all classes dealing with the
manufacture, treatment or handling of fluent materials, and
particularly in classes having feeding or material handling
subclasses. In general, the assignment of patents to the
manufacturing and material treating classes has been on the
basis of the non-dispensing operation, when the means or
steps for performing the nondispensing operation are claimed.
When the means or steps for performing the nondispensing
operation are not claimed, assignment has been to the class
taking the disclosed operation when material feeding
subclasses occur in such art class and are designated and
defined to receive such patents. Classes not having special
subclasses of this type will not take devices falling in the
scope of Class 222, when not claimed in combination with, or
especially adapted for the machines or work of the art class,
unless such class has a large body of art on dispensing, per
se.
Patents having claims to a dispenser classifiable in this
class, and also claims to a method of, or apparatus for,
making such dispenser, are classified in this class, in the
subclass appropriate to the dispenser claimed and
cross-referenced to the appropriate manufacturing class.
GAS OR VAPOR DISPENSERS:
Dispensing of material in a gas or vapor state is provided
for in subclasses 3+. These subclasses were formed on the
basis of apparatus disclosed solely for dispensing a gas or
vapor as the proximate purpose of the apparatus and have, in
subclass 4, the combination of such dispensing means with
means to additionally dispense materials other than gases or
vapors.
Many devices in this class use gas, vapor, or liquid
materials to contact other materials to cause dispensing of
such other materials, or to operate motors or followers to
cause dispensing of other materials, and some devices in this
class utilize gas or vapor to agitate another material while
the latter is being dispensed. Such combinations are not in
subclasses 3+, but are in other following subclasses
appropriate to the invention claimed. Since most of these
devices involve the movement of gases or vapors from one
place to another in the organization, significant gas
dispensing apparatus is often disclosed and claimed as a part
of the liquid or solid dispensing combination. Where the
combination is claimed the gas dispensing subcombination is
cross-referenced to subclasses 3+. It is classified as an
original in subclasses 3+ when the gas or vapor dispensing
subcombination only is claimed.
Most dispensers have vents for the chambers from which
materials are dispensed, either to permit escape of gas or
vapor as the chamber fills or to admit the same as the
chamber empties. Vents were not classified in this class as
dispensers.
For the various combinations within the class having a vent,
or which utilize a gas, vapor, or liquid in various
combinations as above set forth, see the notes to subclass
3.
For gas or vapor dispensers, per se, and for various
combinations having such subject matter as a part thereof
provided for in other classes see the Search Class notes in
References to Other Classes, below, referencing this
section.
ARTICLE DISPENSING:
Article dispensers are classified in Class 221, Article
Dispensing and the definitions and Notes to that class should
be consulted for the statements of the lines of that class
with this class and with other related article dispensing and
feeding classes, including strip feeding.
Dispensers capable of use with either articles or fluent
material of granular, plastic or liquid nature, and claimed
generically are classified in Class 222, that class being
generic to the concept of the two classes (221 and 222).
VOLUME OR RATE OF FLOW METERS, RECORDERS, REGISTERS
This class has volume or rate of flow meters combined with
means for predetermining the total quantity dispensed in
subclasses 14+; volume or rate of flow meters combined with
signals, indicators, registers or recorders specialized for
use with repeated dispensing operations, as registers with
zero-setting or price and volume indicating combinations in
subclasses 23+; volume or rate of flow meters combined with
structure (in addition to that necessary for an operative
volume or rate of flow meter) limited to dispensing in
subclasses 52-73.
The dispensing features, in addition to meter structure,
which, in general, determine classification in Class 222, are
(1) meters having predetermined or preset cut-offs, (2)
meters of the expansible chamber type having ingress or
egress valves which are manually thrown, (3) meters having
manual flow termination, (4) meters combined with storage
tank features where the stored material is dispensed through
the meter, (5) meters with nozzles, spouts, or equivalent
dispensing outlets, and (6) meters combined with a pump
significantly claimed.
For related subject matter, see References to Other Classes
below, that reference this section.
DRIP LEAKAGE OR WASTE CATCHERS
Devices auxiliary to dispensing organizations for catching
drip or waste material are in this class, including receivers
or supports for receivers to be placed to collect material
overflowing or not received by the intended receiver and also
other material escaping from the desired discharge path.
For such devices, see subclasses 108+, and for related art
see References to Other Classes, referencing this section.
COMBINATIONS OF DISPENSER AND INDEPENDENT RECEIVER
Dispensers under the class definition claimed in combination
with either (1) a container or other receiver which is
independent of the dispenser organization, i.e., such
receiver not being a part of the means necessary to the
dispensing operation, or (2) means which perform their
function only in connection with such independent receiver.
The combination defined above is common to all apparatus for
performing any character of operation on material, from those
combinations in which the independent receiver is a mere
receptacle to which the dispenser delivers material for
filling purposes, to those combinations in which the receiver
is a complicated manufacturing or treating apparatus and the
dispenser is a feeding device to deliver material to such
manufacturing or treating apparatus for operation thereon.
Therefore, the great bulk of the patents granted on such
combinations will be found in other classes classified on the
basis of particular adaptation to deliver to receivers of
particular kinds, or on the basis of the particular receiver
(including manufacturing or treating apparatus) claimed.
Where the receiver is defined in such broad terms as to fail
as a basis of classification (i.e., in broad terms, cover
receivers of two or more types separately classified), it is
classified in this class, or other classification appropriate
to the dispenser claimed.
Since the above subject matter occurs primarily in other
classes, classification is in this class only when no other
class provides for such subject matter. For notes on gas
dispensing, see GAS OR VAPOR DISPENSERS above. The Search
Class notes below that reference this section do not attempt
to be exhaustive, specifying only those classes that are
known to have apparatus closely resembling the apparatus in
this class.
Relative to the cleaning of dispensers: Classes 15 and 134
take cleaning devices of the types provided for in those
classes, per se, or in combination with dispensers or fluid
flow systems which are so broadly recited as to appear to
constitute parts of the cleaning means rather than the
articles to be cleaned. Specific dispenser or fluent material
handling structures, including such details as to give a
basis for classification in Class 222 or in Class 137,
combined with means for cleaning such dispensing or handling
structures are classified in Class 222, in subclasses 148+,
or in Class 137, in subclasses 237+. (Combinations of
Dispenser and Independent Receiver)
Some liquid cleaning subcombinations involve no more than
dispensing a cleaning fluid to the article to be cleaned (as
a receiver). Class 137 and Class 222 take such devices as
fluent material handling or dispensing inventions, but where
a cleaning feature (as dissolving of a cleansing material,
surging of the cleaning fluid, etc.) is present,
classification is in Class 134, in appropriate subclass
subclasses thereof. Also see the Search Class note below to
Class 15 referencing this section.
PUMPS
This class has pumps in various combinations with dispensing
features. Dispensing features combined with pumps are:
A. Selectively preset volume responsive cutoff means to
control the quantity discharged (e.g., those which can be
preset to operate through a desired number of cycles), see
subclasses 14+.
B. Totalizing or other registering means, or recording means,
the combination being specialized for repeated operations (as
those provided with zero-setting means or combined price and
volume devices) see subclasses 23+.
C. Position or extent of motion indicators, when other
dispensing features are claimed (e.g., as set forth in (d),
(e), and (f) see subclasses 41+.
D. Measuring means in addition to the pump, see subclasses
23+ and 71+.
E. The combination between a pump and a significantly claimed
container which forms the source of supply for the pump. A
supply container is considered to be significantly claimed
when any one or any combination of the following are recited:
(1) the structural features of the container; (2) the
mounting of the pump on a container closure, (3) particular
relationships between the pump or its controls and the
container, see appropriate subclasses such as 252+ and 372+.
F. The provision of means in addition to pump structure and
its operator to prevent the start of intake before the pump
has reached the end of its discharge operation, see for
example, subclass 34.
G. Discharge outlet (e.g., nozzle) features significantly
claimed, see for example, subclasses 74, 320, 322, 330, 378,
and 379.
For the most part, the notes on dispensers and combinations
of dispensers with other things, in which a pump is part of
the dispenser organization, are placed in Lines With Other
Classes and Within This Class, in this Class Definiton.
For pump structure, and for means to operate and control the
same, including means to vary the pump capacity both with or
without an indicator see the Search Class notes below in
References to Other Classes. In particular, see Classes 137,
366, 406, 417, and 418.
DISCHARGE ASSISTANTS: (E.G., IMPELLERS, PUMPS, CONVEYORS,
MOVABLE TRAP CHAMBERS, ETC.)
Devices combined with containers, or specially adapted for
use with containers, and comprising means acting in addition
to, or against, gravity for either removing material from a
container, or which move, or tend to cause material to move,
to or through a container outlet, have been herein designated
generically "discharge assistants."
The discharge assistants as above comprise any means in
either fluid or solid form, which moves or tends to urge
material to move toward a discharge outlet or into or out of
a trap chamber. Included are means to apply pressure fluids
directly to the material to cause material motion, jarring,
or vibrating means, pumps, pulsators, impellers, pushers,
ejectors, vanes, rolls, screws, mechanical and fluid current
conveyors of all kinds, followers (including followers moved
only be atmospheric pressure), agitators functioning
primarily to cause discharge, and devices for breaking
material bridges or arches.
Movable trap chambers are devices which, when moved to one
position, receive material from a supply and, when moved to
another position, discharge the trapped material. These may
act against or with gravity, sometimes offering no assistance
to discharge except the physical separation of a portion of
the material, and its confinement and control during downward
movement, but they were found so closely related to
nongravity discharge assistants as to cause it to be
advisable to associate the two in the classification (e.g.,
many movable trap chambers were, in addition, mechanical
conveyors).
The above character subject matter occur in numerous
subclasses throughout the class, attention being particularly
called to subclasses 92+ and 193 through 415, in which
subclasses the discharge assistant constitutes the primary
basis of classification.
Since, in most classes, dispensers and combinations thereof
with other things are not separated on the basis of whether
or not they have discharge assistants, notes on this type are
not separately set out, and the notes to Lines With Other
Classes and Within This Class, Pumps, should be consulted.
STATIONARY TRAPS:
Stationary material trapping devices auxiliary to a bulk
supply are included in the class more particularly as
follows: (1) containers having means for separating from the
contained material a quantity less than the whole and
maintaining the same in a position for access thereto by some
removing agency; these may be barometric in type, or a mere
wall or well to reduce the area of material exposed in the
main container (e.g., dispensing inkwells); (2) containers
having receptacles or funnels for receiving or guiding the
container contents, which are carried by, or form part of,
the container and must be separated therefrom before use; (3)
containers having detachable auxiliary chambers which receive
part of the container contents while in place on the
container, but which must be separated for discharge; (4)
containers having auxiliary chambers which receive part of
the container contents and discharge the same through tilting
of the entire organization and which are provided with
passages and baffles arranged to prevent additional material
from entering the trap while the container is tilted; (5)
containers having serial alternately opened valves so related
as to perform a measuring function, the so-called
predetermined-bulk stationary trap, and subcombinations
disclosed as continuously connected to a source of supply.
These devices are related to the movable trap chambers and
other discharge assistants treated inthe section "Discharge
Assistants" above.
Attention is particularly called to subclasses 424.5 through
457, and other subclasses, specified in the notes thereto,
for this type of subject matter.
PATTERN OR SIFTER FORM OUTLET AND WITH MATERIAL SEPARATOR:
This class includes the combination of a dispenser with means
to sift, strain, or filter the material dispensed as an
incident to the dispensing operation (see subclasses 189.01,
189.02+ and 189.06+), and also dispensers having a pattern or
sifter form of outlet (see subclasses 480, 564 and 565, and
the notes thereto). Relative to sifters, strainers, or
filters, combined with a dispenser, this class has this
combination when the separating device is incidental to the
dispenser, while the appropriate separating class has the
separating means with means to deliver material thereto or
therefrom. Relative to pattern or sifter forms of outlet,
this class has the same where there is no structure
specialized to, or intent of, separating, the foraminous
nature of the outlet being for the purpose of holding back
the bulk of the material while permitting the escape of
limited quantities, or assisting to distribute the material
delivered.
For related art, see the section "Hand Manipulable Shakers"
below, and the Search Class notes referencing that section.
HAND MANIPULABLE SHAKERS:
Hand manipulable shaker type dispensers are those which are
adapted to dispense nonfree flowing granular material when it
is kept in motion within the container, which is held in the
hand and moved to and fro to shift the material. In these
dispensers, the outlet is restricted to such an extent that
bridging of the material occurs immediately after the
material is initially brought into contact with the outlet,
usually as a result of tilting the container as for gravity
flow. Dispensing occurs only as a result of repeated contacts
or impacts of the bulk of the material against the outlet
area, as in the use of the ordinary condiment holder or salt
shaker. If a discharge assistant or agitator is present, it
is inertia operated only, having no actuator connected
thereto.
Special provision for this subject matter is made in this
class under the title Hand Manipulable Shaker Type in the
following instances; subclasses 142.1+, for those having
plural sources of supply, e.g., combined salt and pepper
shakers; 196.1+, for those having an inertia operated movable
member which jars or has an impact effect, although it may
also serve as a closure or discharge controller or as a
discharge assistant; 457.5 for those having a generally
U-shaped path through which material is shaken; and 480, for
those having multiple diverse type outlet openings. Hand
manipulable shakers having manually operated discharge
assistants having been classified in the dispenser subclass
appropriate to the type.
Where the outlet is of pattern form, distribution of the
dispensed material is also effected. For pattern or sifter
type dispensing outlets, see the section on "Pattern Or
Sifter Form Outlet And With Material Separator" above, and
the search notes below referencing that section.
For hand manipulable devices having material agitating or
comminuting features see the References to Other Classes
below, that reference this section.
DIPPING AND SAMPLING:
This class has dipping type dispensers and dispensers related
to samplers, see subclasses 576+ and 356+ and the notes to
other subclasses in Class 222 for such art. For related art
in other classes, see the search notes in References to Other
Classes, below, that reference this section.
SHAPING MATERIAL BY EXTRUSION:
Where the outlet of a dispenser has a particular shape, so
that the operation of the dispenser causes a plastic material
to be delivered having a desired shape, classification is in
the class appropriate to the plastic shaping involved.
See the search notes in References to Other Classes, below,
that reference this section.
FURNACE CHARGING AND DISCHARGING:
This class has dispensers, per se, for fuel and other
materials which are intended for delivery to furnaces. Where
features are claimed that specialize the apparatus to
charging or discharging a furnace, classification is in some
other class. See References to Other Classes, below, that
references this section.
SANDING OR ABRADING

See the search notes in References to Other Classes, below,
that reference this section.
See also Pattern or Sifter Form Outlet and With Material
Separator and Sanding or Abrading, and the Search Class notes

VEHICLE LOADING AND UNLOADING:
This class has some vehicular dispensers, see subclasses
176+, but has no other characters of vehicle loading and
unloading.
PUNCTURING INJECTORS AND OTHER NOZZLES, SPOUTS, AND POURING
DEVICES:
The class includes container structures in combination with
one or more dispensing outlet structures; with or without
other openings (as filling or vent openings), or dispensing
outlet structures, per se, and such structures formed to cut
or punch other things, or combined with a cutter or punch for
forming openings in the receiver of the material dispensed.
Dispensing outlet structures comprise the following features
or any combination therebetween: (1) material guide means
(as nozzles, spouts, pouring lips, et cetera), i.e., any
means specialized to guiding the material being discharged
and located either on the interior or exterior of the
container or both. Such structure must be in addition to
mere container openings with or without surrounding flanges
or necks to receive closures. Such guide means may be
stationary relative to the container or movably related
thereto; (2) nonguiding type outlets with flow controllers
(e.g., valves).
Additional openings for nondispensing purposes, such as
filling openings and vents, may be included, and also
closures (as distinguished from flow controllers) for any
opening, means for connecting the various elements together
or means for mounting or operating movable parts. Cutter or
punch combinations are in subclasses 80+.
Patents claiming only the container in combination with the
features above outlined (excepting cutter or punch features)
are in this class starting with subclass 476 and including
all following subclasses. Such features in combination with
other features are in the preceding subclasses, for example,
the combination with a casing or support for the dispenser is
in subclasses 173+, with discharge assistant in subclasses
251+, with container handle or handgrip in subclasses 465+.
Containers in combination with such features are found in
substantially all classes which involve handling of material
in bulk, and in substantially all classes which involve
container structure, classified on special bases and features
in addition to the dispensing features. For such devices for
purposes other than dispensing, and for such devices that are
for dispensing, but are specialized to particular uses, see
below, Restricters, Pipe and Tubular Conduit Structures, and
Valves and Valve Actuation, for restricters and valves.
See the search notes in References to Other Classes, below,
that reference this section.
CONTAINER OR RECEPTACLE STRUCTURE
This class does not have receptacle or container structure
unless combined with dispensing features. Collapsibility,
per se, is considered to be a dispensing feature, relative to
structures disclosed as dispensing containers. For
receptacles, containers and tubular conduit structures, not
involving dispensing features:
See the search notes in References to Other Classes, below,
that reference this section.
CLOSURES
Mere closure structures for containers and other devices
having openings, not claimed in combination with a nozzle,
spout, pouring lip, discharge assistant, or other dispensing
feature, and also closures for spouts where no features of
spout structure are claimed other than those necessary for
the mounting and operation of the closure, are not in Class
222, but in other appropriate classes.
See the search notes in References to Other Classes, below,
that reference this section.
RESTRICTERS, PIPE AND TUBULAR CONDUIT STRUCTURES
This class has neither flow restrictors except those in the
interior of dispenser supply containers, provided for in
subclasses 547 and 564, nor pipe and tubular conduit
structures, per se. For such subject matter:
See the search notes in References to Other Classes, below,
that reference this section.
VALVES AND VALVE ACTUATION:
This class has both single and plural valves and their
actuating means (1) when claimed in combination with a
dispenser, (2) when arranged to control inlet from a bulk
supply into a trap chamber and discharge of the trapped
material from such chamber, and (3) when claimed in
combination with receptacle structure so as to control and
regulate discharge of the container contents.
For valves and valve actuating means not involving such
combinations, see the search notes in References to Other
Classes, below.

Subclass:
196.1
This subclass is indented under subclass 196. Dispensers
adapted to be supported in the hand and shaken to cause
material to move through the outlet and having an
inertia-operated movable part associated with the supply
container for shifting movement when the container is shaken,
whereby jarring results from the impact of the inertia
operated member on the material or container and the material
is loosened, shifted, dragged or impelled through the
outlet.
(1) Note. See class definition, Lines With Other Classes
and Within This Class, Hand Manipulable Shakers.
(2) Note. The movable element may be a discharge controller
or closure, or a discharge assistant, the latter term
including devices analogous to agitators or grinding bodies
but not falling within the definitions of Classes 241 and
366. Mere motion of the material as a result of shaking is
not considered a jarring element.
(3) Note. Since many manually movable elements are capable
of shifting by inertia on movement of the dispenser, only
those designed and constructed solely for this mode of
operation and having no manual actuating means in connection
with the movable element have been placed here.
(4) Note. Discharge assistants of the movable trap chamber
type and stationary trap type dispensers have not been
included, since the presence of the measuring function is
inconsistent with the mode of operation characteristic of
this group.

This subclass is indented under subclass 251. Dispensers
having a chamber so constructed and related to the supply as
to receive material therefrom, which chamber is movable
mounted relative to the supply. The material in the trap
chamber is isolated from the supply either by the relative
movement of the supply and trap chambers or by special means
as flow controllers, closures, etc.
(1) Note. A conveyor type trap chamber functions to convey
(translate) the material from the inlet from the supply to a
spaced outlet while some are movable chambers which, when
moved to one position, permit material flow thereinto from
the supply and in a second position cut off the supply and
permit discharge. The isolation of material must be
accompanied by the motion of the trap chamber relative to the
supply, and the trapped material must be either discharged or
made accessible for use. The isolation may be accomplished
by the travel of the trap chamber beyond a wall of a casing
or supply container, by removal beyond the point where the
angle of repose of the material in the supply is established,
preventing further flow into the trap chamber, or by raising
the chamber above the level of the material in the supply
container.
(2) Note. Many conveyor type or movable trap chambers are
provided for in preceding subclasses in other combinations,
some of these being specially noted below.
(3) Note. Movable trap chamber structures (designated as
