Appl. No.:

8/238730

Inventors:

William R. Rigby - Newark DE

Assignee:

Westvaco Corporation - New York NY

International Classification:

B65D 554

US Classification:

229240

Abstract:

A tearstrip opening for the closure flap of a paperboard container is formed by a single line of tear and an adjacent delamination area located within the closure flap. The tearstrip is applied to one or more of the closure flaps of the container as required. The tearstrip is removed by the combined action of separation of the paperboard along perforations which define the single line of tear and ply separation of the paperboard adjacent to a partial depth cut line of weakness spaced from the single line of tear. When removed, the tear strip releases the closure flap from a side wall of the container while leaving a portion of the closure flap still attached to the side wall.

Abstract:

A multi-use envelope for at least two mailings comprises opposed front and rear panels foldably connected together at their bottom edges and secured together at their side edges by side closure flaps to form an envelope structure. The improvement comprises a pair of closure flaps foldably attached respectively to the top edges of each of the front and rear panels wherein each closure flap has an independent means for sealing and opening the envelope. A first closure flap is folded inside the envelope for the first mailing while the other closure flap is used to close the envelope. Upon receipt, the first closure flap is folded outside the envelope for use in closing the envelope for the second mailing.
