DEFINITION

Classification: 53/403

Gas filling and/or evacuating and closing:

(under subclass 396) Methods of charging and/or evacuating receptacles with gas or vapor only and completing the enclosure.

(1) Note. Where the charging of the receptacle with gas or the evacuation of the receptacle is an incident to the making of the receptacle, such as blowing a glass receptacle or using a vacuum to hold parts together while joining them, the patent is excluded from this class and will be found in the appropriate receptacle making class; see the Notes below.

(2) Note. Where the claims of the patent include any subject matter which limits the process or apparatus to use in manufacturing a particular article, such as claiming operations which could be performed only where an electric switch or electric lamp was being manufactured, the patent is excluded from this class and will be found in the particular class which provides for making the article claimed. If the claims merely recite by name the article being manufactured but the process or apparatus is of general utility, such recitation alone will not be sufficient to exclude the patent from this class.

(3) Note. Where the gas charging or the evacuation involves the use of a chemical reaction either to generate the gas to be charged into the receptacle or to combine with the gas in the receptacle to produce the vacuum (gettering), the patent is excluded from this class and will be found in the particular class which provides for making the article: see the Notes below.

(4) Note. Merely stating that a machine has exhaust heads does not constitute subject matter for this or indented subclasses where the claimed operations performed on the article held in the exhaust is neither exhausting nor gas filling.

(5) Note. Gas charging and/or evacuating combined with assembly other than that of applying a closure to a receptacle is not classified herein; see Notes below for the classes providing for such combination.

(6) Note. This subclass is restricted to gas or vapor handling in combination with closing. Any additional treatment of contents or filling with articles or fluent material requires that the combination be classified in the appropriate subclasses below. SEE OR SEARCH THIS CLASS, SUBCLASS:

79, for apparatus including gas charging and/or evacuating of receptacles combined with closing.

266.1+, for apparatus to fill and close preformed receptacles.

285+, for apparatus to close packages and filled receptacles.

432+, for methods of subjecting the contents of a package to a vacuum or gas treatment.

467, for methods of filling and closing receptacles with contents other than gas.

34, Drying and Gas or Vapor Contact With Solids, appropriate subclasses, especially

92, 191, 242, 284+, 402+, and 558 for miscellaneous processes and apparatus for drying receptacles by the use of gas or vacuum.

65, Glass Manufacturing,

34, for a glassworking or treating process including evacuation of a glass product; and subclass 270 for glass envelope tipping off apparatus with or without evacuating means; see section I in Class 53 for the line between Class 53 and receptacle manufacturing classes.
