DEFINITION

Classification: 215/200

(under the class definition) Closures which are movable or removable and not special to some classified art.

(1) Note. Patents prior to 1940 have been classified on disclosure, not necessarily on the claims.

(2) Note. Patents claiming more receptacle detail than necessary to cooperate with the closure structure will not be found in this or any indented subclass. The broad recitation of common elements of a receptacle (bottom, sides, ends etc.) are not considered receptacle detail and are proper for this and the indented subclasses.

(3) Note. Where the closure is claimed with no significant closure structure but merely in terms of the composition or material of which it is composed, it will be classified in the appropriate composition or material class, even though there is no claim to the composition, per se. In this connection Classes 106, 148, 420, 156, 427. and 520, in the

search note below, should be considered.

SEE OR SEARCH CLASS

49, Movable or Removable Closure, appropriate subclasses for closures of the type there provided for and see the search notes thereto in section IV for the loci of closures in other classes. 106, Compositions: Coating or Plastic. Note particularly the class definitions for the type of composition within the scope of Class 106.

148, Metal Treatment, particularly

400+, for materials which are products of processes of treating metals classifiable in Class 148, or for products distinguished only by the internal structure or characteristics of the metals, metallic composition or alloys comprising such structures.

220, Receptacles,

200+, and see the notes thereto for receptacle closures in general.

222, Dispensing, appropriate subclass for dispensing containers or for closures used with such containers where a dispensing feature, e.g., trap chamber, flow guide, etc., is specifically recited as part of the closure.

420, Alloys or Metallic Compositions, for articles defined solely by their metal or alloy composition.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

262, for methods of applying a liner to a closure cap including a cutting or punching operations.

427, Coating Processes, for processes of coating or impregnating a base and the resultant product or treating such a coated product.

428, Stock Material or Miscellaneous Articles, appropriate subclasses for a stock material laminate in the form of a web or sheet, particularly

544+, for such stock which is all metal or has adjacent metal components. 520, Synthetic Resins or Natural Rubbers, appropriate subclasses for synthetic resins or natural rubber and compositions thereof.
