An integral blank for forming the envelope container, folder, bag and the like is also disclosed.
Claims18
An expansible envelope for shipment, sending or mailing items and being formed from a one-piece unitary blank cut and folded into a substantially flat condition to define:
- a. a rear panel having a top edge, a bottom edge, a right side edge and a left side edge;
- b. a front panel overlying said rear panel and having a top edge, a bottom edge, a right side edge and a left side edge, the dimension between the right side edge and left side edge at substantially any location on the front panel being essentially the same as the dimension between the right side edge and left side edge at a corresponding location on the rear panel;
- c. a bottom panel extending between and integral with each of said front and rear panel bottom edges, the bottom panel being free of any adhesive to permit the substantially flat envelope to be expanded;
- d. right side flap means extending outwardly from one of said right side edges;
- e. left side flap means extending outwardly from one of said left side edges;
- f. right securing means securing portions of said right side flap means to the other of said right side edges;
- g. left securing means securing portions of said left side flap means to the other of said left side edges;
- h. the substantially flat envelope adapted to be expanded such that the bottom panel and flap means extend laterally from and are interposed between the front and rear panel to define a compartment therebetween, said compartment having an opening between said top edges and all of said flap means and said securing means being disposed intermediate one of said top edges and said bottom panel in expanded condition of the envelope;
- i. a cover flap extending from said one top edge, said cover flap being foldable over the other top edge to thereby overlie said opening;
- and
- j. said cover flap adapted to be secured in a position in which said cover flap overlies said opening.
