Abstract
Abstract An envelope assembly of a succession of envelopes each includes a front and back panel and extractable insert material contained therein, the insert material comprising a top-opening return mailer envelope connected to a portion of the envelope by means of a panel forming a portion or chip of the return envelope which is separable therefrom, and which is retained with the envelope upon extraction of the insert. As an alternative, the chip of the return envelope is connected to an insert sheet within each envelope.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
An envelope assembly formed of a continuous web having spaced transverse lines of weakening defining a succession of interconnected sealed envelopes, comprising: front and back panels, and insert material within each sealed envelope; said insert material comprising interconnected upper and lower panels forming a return envelope having an opening along one edge thereof, one of said return envelope panels being separable along a keen line of weakening provided therealong, the other of said return envelope panels having a flap foldable along a fold line provided thereon; attaching means connecting a portion of said insert material in each said sealed envelope with said sealed envelope, said portion comprising a section of said one panel which is superimposed over said flap and which is separable along said keen line of weakening; and a tear strip on each said sealed envelope for opening said sealed envelope and freeing said return envelope from said sealed envelope, said section of said return envelope being retained with said sealed envelope upon the freeing of said return envelope from said sealed envelope.
Claim 2
Dependent Claim
175 words
An envelope assembly formed of a continuous web having spaced transverse lines of weakening defining a succession of interconnected sealed envelopes, comprising: front and back panels, and insert material within each sealed envelope; said insert material comprising interconnected upper and lower panels forming a return envelope having an opening along one edge thereof, one of said return envelope panels being separable along a keen line of weakening provided therealong, the other of said return envelope panels having a flap foldable along a fold line provided thereon; attaching means connecting a portion of said insert material in each said sealed envelope with said sealed envelope, said portion comprising a section of said one panel which is superimposed over said flap and which is separable along said keen line of weakening; and a tear strip on each said sealed envelope for opening said sealed envelope and freeing said return envelope from said sealed envelope, said section of said return envelope being retained with said sealed envelope upon the freeing of said return envelope from said sealed envelope.
Claim 3
Dependent Claim
33 words
The envelope assembly according to claim 1, wherein said tear strip is located along one end of said sealed envelope, and said keen line of weakening is disposed perpendicular to said tear strip.
Claim 4
Dependent Claim
20 words
The envelope assembly according to claim 2, wherein said extends along said section return envelope between opposite end edges thereof.
Claim 5
Dependent Claim
68 words
The envelope assembly according to claim 2, wherein said tear strip is superimposed on one end of said return envelope and the opposite end of said return envelope lies inwardly of the opposite end of said sealed envelope to facilitate separation of said return envelope along said keen line of weakening as said opposite end of said sealed envelope and said tearstrip are moved away from one another.
Claim 6
Dependent Claim
222 words
An envelope assembly formed of a continuous web having spaced transverse lines of weakening defining a succession of interconnected sealed envelopes, comprising: front and back panels, and insert material within each sealed envelope; said insert material comprising interconnected upper and lower panels forming a return envelope having an opening along one edge thereof, one of said return envelope panels being separable along a keen line of weakening provided therealong, the other of said return envelope panels having a flap foldable along a fold line provided thereon; said insert material further comprising an insert sheet removably connected with said sealed envelope along at least one edge thereof; attaching means connecting a portion of said return envelope in each said sealed envelope with said insert sheet therein, said portion comprising a section of said one panel which is superimposed over said flap and which is separable along said keen line of weakening; and a tear strip on each sealed envelope for opening said sealed envelope and freeing said insert material from said sealed envelope, said return envelope and said insert sheet thereby together being freed from said sealed envelope, and said return envelope being separable from said insert sheet along said keen lines of weakening whereby said section is retained with said insert sheet upon separation of said return envelope and said insert sheet.
Claim 7
Dependent Claim
