Two compartmented envelope
First Claim
1. A two compartment envelope comprising, in combination, a first generally rectangular blank defined by a rear panel and a front panel foldably attached to one another along a transverse fold line, a pair of side closure flaps foldably attached to the side edges of said rear panel and a top closure flap foldably attached to the upper transverse edge of said rear panel, and a second blank in the form of a patch adhered to the inside surface of said front panel, the improvement comprising:
- (a) a recess along the transverse edge of said front panel remote from the fold line connecting said front and rear panels;
(b) a contoured extension along the transverse edge of said top closure flap for simultaneously sealing the first envelope compartment formed between said front panel and said patch and the second compartment formed between said rear panel and said patch;
(c) a perforated line in said top closure flap located so as to separate the contoured extension of said top closure flap from the main portion thereof for permitting independent access to said first compartment without disturbing the contents of said second compartment; and
,(d) a pattern of adhesive applied to said top closure flap in the form of a centrally located strip that overlaps said perforated line and a pair of separate patches outboard of said centrally located strip whereby said centrally located adhesive strip simultaneously seals the first compartment and the central portion of said second compartment while said adhesive patches seal the outboard portions of said second compartment.

Abstract
A compartmented mailing envelope for combining both first and third class mail includes a small front compartment and a larger rear compartment. The two compartments are formed from a blank of paper on which there is adhered a patch of paper. A single top closure flap is foldably attached to one end of the blank for sealing both compartments simultaneously. Meanwhile, a means is provided in conjunction with the top closure flap to provide access to the small front compartment without disturbing the contents of the larger rear compartment.

3. A two compartment envelope for both first and third class mail comprising a rear panel having transverse upper and lower edges and a pair of end edges, a pair of side flaps foldably attached to said end edges, a top closure flap foldably attached to the upper transverse edge, a front panel foldably attached to said lower transverse edge and a generally rectangular patch having dimensions slightly smaller than said front panel adhered along three sides to the inside of said front panel to form the first class compartment, the improvement comprising:
-
(a) a contoured extension along the outer edge of said top closure flap; (b) a cooperating recess along the free edge of said front panel to coincide with the contoured extension on said closure flap; (c) a perforated line separating the contoured extension of said top closure flap from the main portion thereof for permitting access to said first class compartment independently of the main body of said envelope; and
,(d) a centrally located adhesive strip that overlaps said perforated line applied to said top closure flap for simultaneously sealing both compartments of said envelope and a pair of separate adhesive patches located outboard of said centrally located adhesive strip for sealing the outboard portions of the main body of said envelope.
