Claims
- 1. A compartmented envelope formed from a single blank of envelope material and including at least one integral panel for dividing the envelope into compartments consisting of a window compartment that is smaller in length and width than the exterior dimensions of the envelope and a second full sized compartment in front-to-back relation comprising, an elongated rear panel having two long edges and two shorter edges, a front window panel foldably attached to one of the long edges of said rear panel, a sealing flap foldably attached to the other long edge of said rear panel and a first end closue flap foldably attached to one of the shorter edges of said rear panel, the improvement comprising:
- (a) a second end closure flap foldably attached to the opposed shorter edge of said rear panel, said second end closure flap being of a length sufficient to divide the envelope into its two compartments but not long enough to overlap the opposite end closure flap;
- (b) a first area of pressure sensitive adhesive applied to said front panel;
- (c) at least one additional area of pressure sensitive adhesive applied to said sealing flap for mating with said first area to seal both compartments
- (d) separate adhesive areas applied to said sealing flap and to said second end closure flap which, when mated together, additionally seal the only compartment full-sized;
- (e) a perforated line in said sealing flap between the adhesive areas applied thereto for permitting independent access to said window compartment; and,
- (f) a third area of pressure sensitive adhesive applied to said second end closure flap, all of said pressure sensitive adhesive being of the type that will only adhere to itself whereby when said sealing flap is folded to close the envelope, the third area of adhesive mates with an area of adhesive on said sealing flap flap to retain an item that is smaller in length than said envelope in position in the window compartment of said envelope.
- 2. The envelope of claim 1 wherein said first end closure and said second end closure flap are of substantially the same length and together they divide the envelope into its two compartments.
- 3. The envelope of claim 2 wherein separate areas of adhesive are applied to both said first and second end closure flaps for sealing the window compartment.
- 4. The envelope of claim 3 wherein there is at least two additional areas of pressure sensitive adhesive applied to said sealing flap.
