B05B - Definition 
Definition statement
This subclass 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 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;
- 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 subclass B05C, "projection" relates to the application of a continuous stream of liquid or other fluent (e.g. particulate) material to a surface. In subclass 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.

Glossary of terms
In this subclass, 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. |
