Apparatus as above, for the release or projection of streams or sprays of other fluent materials, e.g. particulate material entrained in a gas, into the atmosphere or into a chamber.

Examples of such apparatus, and subcomponents thereof covered by this subclass, include:

Nozzles, spray heads, shower heads, roses, perforated pipes, spouts or other outlets, with or without auxiliary devices such as valves or heating means.

Spraying or sprinkling apparatus with moving outlet elements or moving deflecting elements.

Electrostatic spraying apparatus or installations.

Spraying apparatus for discharge of liquids or other fluent materials from two or more sources, e.g. of liquid and air or powder and gas.

Single-unit, i.e. unitary, hand-held apparatus in which flow of liquid is produced by the operator at the moment of use, e.g. by pumping, by squeezing a liquid container or by compressing a compressible bulb.

Spraying plants, e.g. with means for supporting or feeding work; spray booths.

Other spraying-type machines or apparatus, including fountains.

Means for heating, mixing or pressurising of gases, liquids or other fluent materials that are sprayed, sprinkled, misted, released or projected using the apparatus of this subclass.

Delivery control means or other details or accessories for use with the apparatus of this subclass.

Relationship between large subject matter areas

Subclass B05C relates to apparatus for applying liquids or other fluent materials to surfaces in general. This subject matter generally relates to contact methods e.g. spreading, pouring, dipping, rubbing, using rollers, using fluidized bed techniques etc. but not to spraying or atomising apparatus which is covered by subclass B05B. B05C also relates to apparatus for projecting liquids or other fluent materials onto surfaces (B05C 5/00) or to the inside of hollow work (B05C 7/02), and further to apparatus specially adapted for the projection of particulate material onto surfaces (B05C 19/04). In B05C, ‘projection’ relates to the application of a continuous stream of liquid or other fluent (e.g. particulate) material to a surface. In B05B, ‘projection’ relates to the release of a discontinuous stream of drops, droplets or a cloud of particulate material into the atmosphere or into a chamber to form a mist or the like.

Subclass B05D relates to processes (including processes performed by spraying) for applying liquids or other fluent materials to surfaces in general.

Special rules of classification within this subclass

Arrangement for cleaning discharge opening/devices/dispensing heads of apparatus belonging to subclass B05C are classified in the relevant place of B05C as well as in B05B 15/02 and subgroups.

Considering the possible broad interpretation of the scope of B05B, it is essential to pay attention to all references appearing in many titles of the B05B places. All devices relating to specific application fields are normally not classified in B05B unless some general function aspects are considered of relevance and are therefore (also) classified in B05B.

Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
Coating
The applied material. A coating may be a solidified layer originally applied as a liquid (e.g. dried paint) or a layer of material which, once applied, remains in a liquid or semi-liquid state (e.g. lubricant).
Liquid or fluent
designates materials which can flow, e.g. liquids, including solutions, dispersions and suspensions, as well as semi-liquids, pastes, melts and particulate materials.
Particulate materials
Solid materials in the form of very small pieces, e.g. powders, granules, short fibres or chips.
with integral means for shielding the discharged liquid or other fluent material, e.g. to limit area of spray; with integral means for catching drips or collecting surplus liquid or other fluent material (means for any of these purposes, per se, B05B 15/04 )

Apparatus of the B05B 7/00 type which are to be carried on or by a person, e.g. by hand, and which have a container are classified in B05B 7/2405+, B05B 7/244+.

B05B 11/00 takes precedence.

Apparatus to be carried on or by a person, e.g. of knapsack type ([N: B05B 9/0426, B05B11/00 take precedence]; details or components, e.g. casings, bodies of portable power-driven tools not particularly related to the operation performed B25F 5/00 )

Attention is drawn to the following places, which may be of interest for search:
Details or components, e.g. casings, bodies, of portable power-driven tools not particularly related to the operation performed
Single-unit, i.e. unitary, hand-held apparatus [N: comprising a container and a discharge nozzle attached thereto], in which flow of liquid or other fluent material is produced by [N: the muscular energy of] the operator at the moment of use [N: or by an equivalent manipulator independent from the apparatus (apparatus with an external source or the possibility of permanent accumulation of pressure for discharging the liquid or fluid material B05B 7/00, B05B 9/00 )]
Relationship between large subject matter areas

The expression "Single-unit, i.e. unitary, hand-held apparatus comprising a container and a discharge nozzle attached thereto" is very important to properly define the border line with other areas of B05B as well as with other technical fields, e.g. B65D, A47K, F04B.

Single-unit, i.e. unitary, hand-held apparatus in which there exists a possibility to accumulate permanently a certain pressure on the material, e.g. liquid, and wherein this pressure is used to discharge the material through the outlet are not classified in B05B 11/00 and sub-groups, but in B05B 9/0805 and subgroups or B05B 7/2402 and subgroups.

In apparatus classified in B05B 11/309 and subgroups, energy can be stored, e.g. in the form of a compressed spring. However the stored energy does not generate permanent pressure on the material for discharging the latter. Only when the spring is released is the material pressurized in the pump chamber.

In apparatus classified in B05B 11/004 and sub-groups, reservoirs containing the material may be permanently pressurized, e.g. by a follower piston pushed by a spring. However this pressure is not used to discharge the material but only to feed the latter to a discharge device, e.g. a pump.

Aerosol containers are classified in B65D 83/14 and subgroups.

Apparatus of the B05B 7/00 type which are to be carried on or by a person, e.g. by hand, and which have a container are classified in B05B 7/2405+, B05B 7/244+.

Apparatus of the B05B 9/00 type which are to be carried on or by a person, e.g. by hand, and have a container are classified in B05B 9/0805+.

Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:

In this group, the following terms or expressions are used with the meaning indicated:

Pump
A device comprising a chamber into which the material is first sucked from the container through an inlet, then delivered out of the chamber, e.g. sprayed, through an outlet. Inlet and outlet can be equipped with valves.
Lift valve
A valve as defined in main group F16K 1/00, i.e. a cut-off device with closure members having at least a component of their opening and closing motion perpendicular to the closing faces.
Gate valve or sliding valve
A valve as defined in main group F16K 3/00, i.e. cut-off device with closing members having a sliding movement along the seat for opening and closing.
the flow being effected by a pump
Relationship between large subject matter areas

For historical and pragmatic reasons all single-units, i.e. unitary, hand-held apparatus wherein the flow is effected by a pump are classified in B05B11/25 and subgroups, irrespective of whether the material is sprayed or simply dispensed.

This is justified by the fact that technical features of spray pumps are similar if not identical to the ones of dispensing pumps. Many patent applications do not even mention the word "spray" in the claims/description, thereby avoiding to restrict the scope of protection.

The JPO appears to classify in the same way as many single-units hand-held apparatus with dispensing pumps are classified in IPC main group B05B 11/00.

A consequence of the above is that IPC group B65D47/34 which covers a similar concept, i.e. containers having closures with discharge by pumping, does not exist in CPC, in agreement with examiners and classifiers of B65D.
