DEFINITION

Classification: 53/221

(under subclass 220) Apparatus in which one surface of a contents contacts a cover member and forces the cover member through a second member having a substantially completely enclosed opening, the entire periphery of the opening smoothing and/or wiping the cover member around the contents so that the contacting surface of the contents and the surfaces contiguous thereto are snugly enclosed by the cover member.

(1) Note. It is not necessary that all portions of the cup or pouch extend above the top of the contents.

(2) Note. This particular enclosure of the contents constitutes and "initial wrap"; see the Class Definition,
