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.

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.

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.
