CLASS 220,	RECEPTACLES
Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This is the residual class of receptacles comprised of a peripheral wall with at least one closed end, and having an access opening which may be an open end of the receptacles, or which may be provided in the peripheral wall or closed end of the receptacle. Receptacles of this class type must function, by disclosure, to hold contents which in turn are to be eventually removed from the receptacle. This is also the residual locus for closures for receptacles. This is also the residual locus for attachments for receptacles.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

Some specific art structures remain in this class which do not function by disclosure to hold contents which in turn are to be eventually removed from the receptacle; particularly those in subclasses 2.1+, subclasses 3.2+, and some electrical and sectional housings.

Designs for receptacles are in the design classes. See References to Other Classes, below.

For other receptacles, see References to Other Classes, below.

See the Notes to subclasses 2.1+ of this class (220) for the distinction between the envelopes, boxes, and housings for electric lamps, discharge devices, and similar devices in Class 174 and those in other classes, and the Notes to subclasses 3.2+ of this class (220) for the distinction between the boxes and housings for electrical devices in Class 174, and those in other classes.

See the Notes to subclasses 2.1+ of this class (220) for the distinction between the envelopes, boxes and housings for electric lamp and discharge devices which are in Class 313 and those in other classes.

229,	Envelopes, Wrappers, and Paperboard Boxes, for receptacles of that material. The line between classes 220 and 229 is as follows. Given a claim to a container which includes (1) a paperboard layer and (2) either a rigid metal or a rigid plastic layer, the layer which is considered to be the primary layer or the support layer controls classification, i.e., a container made from metal is classified in Class 220. A container made from rigid or semi-rigid thermoplastic is classified in Class 220 unless it folds in the manner of a paperboard container. A container made from paperboard or a container made from rigid or semi-rigid thermoplastic and which folds in the manner of a paperboard container made from a blank is classified in Class 229. A paper container made of molded pulp or molded paperboard is classified in Class 229. A paperboard container having a metal or thermoplastic closure is classified in Class 229. Any doubt is resolved in favor of Class 220. Examples: (1) If one layer forms a complete container and the other does not, the claim is classified on the basis of the complete container; (2) A paperboard container with a metal foil layer is classified in Class 229; (3) A paperboard container with a thin thermoplastic layer is classified in Class 229; (4) A paperboard container with a removable inner container made of metal or rigid or semi-rigid thermoplastic is classified in Class 229; (5) A metallic or a rigid or semi-rigid thermoplastic container having a removable inner paperboard container is classified in Class 220.

248,	Supports, for receptacle supports. In general, as between the receptacle classes and the support classes, the receptacle classes provide for the combination of a receptacle plus support: except, the support classes will accept a claim to a support combined with a receptacle, wherein the claim (1) nominally recites the receptacle, or (2) recites only so much of the receptacle structure as is needed to cooperate with the support, or (3) recites only those receptacles features which have been modified specifically to cooperate with the support.

ENVELOPE FOR ELECTRIC LAMP OR SIMILAR DEVICE:

This subclass is indented under the class definition. Envelopes, casings and housings, designed for use with electric lamps, electric space discharge devices and similar devices.

(1) Note. This subclass includes envelopes made of vitreous, ceramic or nonmetallic plastic material for electric lamps, electric space discharge devices, electric switches and similar devices where the claimed structure is of general application and not limited to use with any specific electric device or is not limited by claimed structure to electrical use.

(2) Note. This subclass provides only for the structure of the envelope and associated accessories such as an attached base but does not provide for any structure which is limited to electrical use such as lead-in wires for conducting electricity through the wall of the envelope, casing or housing.

(3) Note. An envelope is defined for the purpose of classification in this and the indented subclasses as being a gas tight enclosure designed to be evacuated or filled with a gas or vapor. In general the distinction between an envelope and a jacket or casing is that the envelope is to be sealed so as to be gas tight.

(4) Note. Many of the receptacles in this and the indented subclasses are made in whole or part of glass or other ceramic material but this and the indented subclass are not limited to receptacles made of such material.

(5) Note. As this and the indented subclass are based on the function of the casing or housing, the art in these subclasses is cross-referenced into the succeeding subclasses of this class for structural features which are of general utility.
