Definition

This class provides for certain special types of receptacles called Paperboard Boxes, File Folders, and Envelopes, and further provides for certain special types of articles called Postal Cards and Packets, and Wrappers for a mercantile unit.

(A) This is the class for envelope being defined as a substantially flat receptacle having two walls joined at their edges to form a pocket-like enclosure made of paper or paper substitute material, which is disclosed for enclosing a sheet-like article (e.g., document) while it is being transported (e.g., mailed).

(1) Note. An envelope is usually made of paper or paper-like material such as a flexible sheet of cellulosic or resinous material (e.g., plastic film).

(B) This is the class for file folders, a file folder being defined as a substantially flat receptacle having two walls connected at a bottom fold line, or to an expandable bottom wall; and which is disclosed for storing a sheet-like article (e.g., document) in a file cabinet.

(1) Note. A file folder can have closed ends, and may be expandable to a nonflat shape. (2) Note. A file folder is usually placed in a file cabinet under a heading which facilitates retrieval. (3) Note. A file folder may have the secondary function of holding an article while being transported.

(C) Wrappers- This is the class for wrappers, a wrapper being defined as a single-use covering having a structural element (e.g., fastener, seal, etc.) or a specified shape adapting it for wrapping a mercantile unit, and as being made of paper or paper-substitute material.

(1) Note. An example of a paper-substitute material is a flexible sheet of cellulosic or resinous material (e.g., plastic film). (2) Note. A mercantile unit includes means in or by which goods (article or material) are displayed, protected, packaged or arranged in a particular manner to facilitate sale, transportation in commerce, use or storage. (3) Note. A "single-use" covering is one which is discarded after use. (Lines With Other Classes and Within This Class for flexible protective article covers that are reusable).

(D) This is the class for paperboard boxes, a paperboard box being defined as a container made from material similar in composition to paper but thicker and stiffer in character, the container having a bottom portion for supporting content, peripheral wall structure for at least partially surrounding the content, and an access opening intended for the insertion or removal of content.

(1) Note. A box made of cellulosic or resinous material (e.g., plastic) which is similar in character to paperboard, and which is manipulated in the same manner as paperboard (e.g., folded from a blank) is included here. See Lines With Other Classes and Within This Class for containers not provided for elsewhere.

(E) This class also provides for postal cards, letter sheets, and packets, a post card being defined as a card peculiarly adapted carry information and be mailed by itself; a letter sheet being defined as a sheet peculiarly adapted to carry information, and is disclosed as being defined as a mailing sheet having an enclosure, the packet being peculiarly adapted to carry information and be mailed as a unit.

RELATION TO SUPPORT CLASSES

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 (a) nominally recites the receptacle, or (b) recites only so much of the receptacle structure as is need to cooperate with the support, or (c) recites only those receptacle features which have been modified specifically to cooperate with the support.

Class 150, Purses, Wallets, and Protective Covers, provides for flexible protective article covers which are reusable.

Class 220, Receptacles, takes containers not provided for elsewhere.
