CPC Definition - Subclass B05B
This place covers:
Apparatus for the release or projection of drops or droplets into the atmosphere or into a chamber to form a mist or the like. The materials to be projected may be suspended in a stream of gas or vapour.
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.
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.

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 15/50 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.
In this place, 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. |
Examples of places where the subject matter of this place is covered when specially adapted, used for a particular purpose, or incorporated in a larger system:
Means for limiting the area of spray, or for the collection or re-use of excess material |
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 of the B05B 9/00 type which are to be carried on or by a person, e.g. by hand, and have a container being put under pressure are classified in B05B 9/0805+.
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 being put under pressure are classified in B05B 9/0805+.
B05B 11/00 takes precedence.
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+.
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 |
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 11/109 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 11/0041 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 as well as their subgroups.
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 and subgroups.
Attention is drawn to the following places, which may be of interest for search:
In this place, 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. |
This place covers:
Means to restrict, limit the actuation by the user by limiting the movement of the controlling means.
Such restricting means are:
- locking means, e.g. for locking the valve in the open or close position
- stop means
Biasing means such as springs are not considered as means for restricting the movement.
If there is only one locking or stopping position, classification is made in B05B 12/0024 and subgroup.
