DEFINITION

Classification: 493/51

CONTAINER MAKING:

(under the class definition) Method or apparatus comprising the step of or means for performing a final operation in the construction of a receptacle intended to serve to encompass

and hold material or an article.

(1) Note. The "final operation" required in the definition of this subclass may be considered to be that operation that changes something less than a container into a container. For example, closing the bottom of a tube forms a container if it is intended to hold goods, and that step alone will be found herein; whereas, placing a handle on a previously formed container or on a blank to be formed into a container will not be found in this and the indented subclasses unless claimed in combination with a step which may be considered to be the required "final operation".

(2) Note. Making a container hold material better is considered to be the "final" operation required by the definition of this subclass; e.g., lining a container, applying a lid to a container, etc., makes the container hold material better and is considered to be proper for this and the indented subclasses.

(3) Note. A common folder for holding sheet material, with a front and back cover is not considered to be a container because it does not encompass the contained article; however, a similar folder with straps on the sides to attach the upper corners of the front and back covers is a container because it does encompass the contained article.

SEE OR SEARCH THIS CLASS, SUBCLASS:

186+, for making a pliable container and for making an envelope or closed folder, e.g., a record envelope, even if the wall thereof is rigid, provided the envelope or folder is formed at its margin with a single fold only, thereby making no allowance for the thickness of the contents.
