CLASS 220, RECEPTACLES

SECTION I - CLASS DEFINITION

This is the residual class of receptacles comprised of aperipheral wall with at least one closed end, and havingan access opening which may be an open end of thereceptacles, or which may be provided in the peripheralwall or closed end of the receptacle. Receptacles of thisclass type must function, by disclosure, to hold contentswhich in turn are to be eventually removed from thereceptacle. This is also the residual locus for closuresfor receptacles. This is also the residual locus forattachments for receptacles.

SECTION II - LINES WITH OTHER CLASSESAND WITHIN THIS CLASS

Some specific art structures remain in this class whichdo not function by disclosure to hold contents which inturn 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. SeeReferences to Other Classes, below.

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

See the Notes to subclasses 2.1+ of this class (220) forthe distinction between the envelopes, boxes, and hous-ings for electric lamps, discharge devices, and similardevices in Class 174 and those in other classes, and theNotes to subclasses 3.2+ of this class (220) for the dis-tinction between the boxes and housings for electricaldevices in Class 174, and those in other classes.

229, Envelopes, Wrappers, and Paperboard Boxes, for receptacles of that material. The linebetween classes 220 and 229 is as follows.Given a claim to a container which includes (1)a paperboard layer and (2) either a rigid metalor a rigid plastic layer, the layer which is con-sidered to be the primary layer or the supportlayer controls classification, i.e., a containermade from metal is classified in Class 220. Acontainer made from rigid or semi-rigid ther-moplastic is classified in Class 220 unless itfolds in the manner of a paperboard container.A container made from paperboard or a con-tainer made from rigid or semi-rigid thermo-plastic and which folds in the manner of apaperboard container made from a blank isclassified in Class 229. A paper containermade of molded pulp or molded paperboard isclassified in Class 229. A paperboard con-tainer having a metal or thermoplastic closureis classified in Class 229. Any doubt isresolved in favor of Class 220. Examples: (1)If one layer forms a complete container and theother does not, the claim is classified on thebasis of the complete container; (2) A paper-board container with a metal foil layer is classi-fied in Class 229; (3) A paperboard containerwith a thin thermoplastic layer is classified inClass 229; (4) A paperboard container with aremovable inner container made of metal orrigid or semi-rigid thermoplastic is classified inClass 229; (5) A metallic or a rigid or semi-
