Last Updated Version: 2023.08
SPRAYING APPARATUS; ATOMISING APPARATUS; NOZZLES (spray-mixers with nozzles B01F 25/72; processes for applying liquids or other fluent materials to surfaces by spraying B05D)
Definition statement

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.
Relationships with other classification places

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

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.

Glossary of terms

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.

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 12/16, B05B 12/32, B05B 14/00)

Single-unit hand-held apparatus in which flow of contents is produced by the muscular force of the operator at the moment of use
Definition statement

This place covers:

Single-unit hand-held apparatus comprising a container and a dispensing nozzle attached thereto, in which flow of contents is produced by the muscular force of the operator at the moment of use.

Relationships with other classification places

The expression "Single-unit hand-held apparatus in which flow of contents is produced by the muscular force of the operator at the moment of use" 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 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.
