DEFINITION

Classification: 118/400

(under the class definition) Coating apparatus wherein the work to be coated is (1) introduced or dipped wholly or partially into a bath, puddle or other enclosed or restricted bulk supply of coating material, or (2) where a supported stream, column, puddle or other enclosed restricted bulk supply of coating material is brought into contact with the work to be coated.

(1) Note. The base may contact the coating material in the bulk supply of coating material or it may contact only a thin

column of coating material which has been conducted away from the bulk supply of the coating material.

(2) Note. To be classified in this and the indented subclasses coating material must be supported up to the instant it contacts the base to be coated and must be more than a film on a solid supporting surface. Compare, for example, subject matter of subclass 300 in which the coating material is flung or projected against the base, and subclass 200 for solid applicators supporting a wetting film of coating material.

26+, for immersion coating devices in which the work is edible.

56, for the combination of an immersion coating device and means to manipulate the work in some manner to distribute or move surplus coating material. 76+, for coating apparatus in which the work contacts a solid self-sustaining block of coating material.

200+, and see (2) Note, above.

300+, and see (2) Note, above.
