Last Updated Version: 2025.08
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.

Nozzles or guns for the release of gas only, e.g. air or blowing guns or nozzles.

Projection of droplets of coating material out of numerous closely spaced nozzles by using an inkjet technology to form plain, i.e. not patterned, coating.

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, or using rollers or fluidized bed techniques, but not to spraying or atomising apparatus that is covered by subclass B05B. Also, subclass B05C relates to apparatus for projecting liquids or other fluent materials onto surfaces (group B05C 5/00) or to the inside of hollow work (subgroup B05C 7/02), and further to apparatus specially adapted for the projection of particulate material onto surfaces (subgroup 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.

Special rules of classification

Apparatus for applying fluent materials to surfaces, in general, e.g. arrangements for cleaning discharge openings, devices or dispensing heads, of apparatus belonging to subclass B05C are classified in the relevant place of B05C, as well as in B05B 15/50.

Considering the possible broad interpretation of the scope of subclass 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 subclass B05B.

Glossary of terms

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

coating

Figures 1a, 1b and 1c illustrate a sprinkler (100). The water flow through sprinkler (100) is adjusted by aligning spaces or apertures (130A) formed by throttle plate (130) with apertures (124B) in drive plate (124). Therefore, increasing alignment of apertures (130A, 124B) increases the flow out of sprinkler (100), while decreasing alignment of apertures (130A, 124B) decreases the flow. Throttle plate (130) is located below drive plate (124) and includes centre aperture (130B that engages with mating lower end (116A) of flow adjustment shaft (116). In this respect, rotating flow adjustment shaft (116) also rotates throttle plate (130) relative to drive plate (124). Throttle plate (130) is frictionally engaged to the bottom of drive plate (124), rotating throttle plate (130) with drive plate (124). Additionally, the flow of water through sprinkler (100) may cause slight movement and pressure of throttle plate (130) upwards against drive plate (124), further increasing friction. The frictional or clutching force between throttle plate (130) and drive plate (124) is such that it can be overcome when the user adjusts flow adjustment member (112) and therefore the flow of sprinkler (100).

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.

Controlling in general

G05

{associated with means for restricting their movement}
Definition statement

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.

Example of a locking means, with several positions:

Special rules of classification

Reference B05D is non-limiting in group B05B 13/00. CPC will be updated or corrected once this inconsistency is resolved in IPC.

Group B05B 13/00 is used to classify subject matter that is not fully covered by groups B05B 1/00 - B05B 11/00, so group B05B 13/00 can be used in addition to groups B05B 1/00 - B05B 11/00 when subject matter for B05B 1/00 - B05B 11/00 is also to be classified. For example, a means for supporting work can be classified in subgroup B05B 13/02 when it is used with a nozzle not requiring classification in group B05B 1/00, or a means for supporting work can be classified in subgroup B05B 13/02, in addition to classifying the nozzle used therewith in group B05B 1/00.

Means for supplying or discharging of liquid or other fluent material for applying liquids or other fluent materials to surfaces of objects or other work by spraying are covered by one of groups B05B 1/00 - B05B 12/00.

{Machines or plants for applying coating liquids or other fluent materials by inkjet}
Definition statement

This place covers:

Machines or plants for inkjet coating onto work surfaces, e.g. by using nozzle heads provided with numerous closely spaced outlets. The resulting coating formed is a plain coating layer that is not patterned when applied onto the work surfaces.

Illustrative examples of subject matter classified in this place:
