DEFINITION

Classification: 53/138.3

Bag closing:

(under subclass 138.2) Apparatus wherein the cover secured is three dimensional, i.e., has a bottom and side walls but is open at the top, and is intended to not retain its shape during use, which apparatus applies the bifurcated member to secure to top of the cover closed.

(1) Note. An envelope is not considered to be "three dimensional" and therefore an apparatus for closing an envelope with a staple or a clip is not considered proper for this subclass.
