Abstract

Abstract The front and back plies of the continuous mailer assembly are secured together by a hot melt pressure sensitive adhesive. This adhesive secures the plies together in a fixed permanent relation. When the assembly is unfolded from a zig zag stack, "tenting" is eliminated.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 101 words
In a continuous mailer assembly, the combination comprising a first ply having a plurality of transverse lines of weakening to define a series of envelope fronts; a second ply having a plurality of transverse lines of weakening to define a series of envelope backs; and at least one line of hot melt pressure sensitive adhesive between said plies and securing said plies together, said adhesive being characterized in that after its open time has ended, said adhesive remains very tacky and is capable of adhering to another ply of paper at any time that the paper makes contact with said adhesive.
Claim 2
Dependent Claim 101 words
In a continuous mailer assembly, the combination comprising a first ply having a plurality of transverse lines of weakening to define a series of envelope fronts; a second ply having a plurality of transverse lines of weakening to define a series of envelope backs; and at least one line of hot melt pressure sensitive adhesive between said plies and securing said plies together, said adhesive being characterized in that after its open time has ended, said adhesive remains very tacky and is capable of adhering to another ply of paper at any time that the paper makes contact with said adhesive.
Claim 3
Dependent Claim 15 words
The combination as set forth in claim 1 wherein said adhesive is a Fuller #HM-1089-B.
Claim 4
Dependent Claim 35 words
The combination as set forth in claim 1 which further comprises at least one series of inserts between said plies, each said insert being disposed between a respective envelope back and an opposed envelope front.
Claim 5
Dependent Claim 28 words
The combination as set forth in claim 3 wherein each respective insert is peripherally free of said respective envelope back and front on at least one side thereof.
Claim 6
Dependent Claim 29 words
The combination as set forth in claim 1 which includes two lines of said hot melt pressure sensitive adhesive between said plies in parallel and longitudinal of said assembly.
Claim 7
Dependent Claim 83 words
A stacked array of interconnected envelopes disposed in layers of at least one envelope per layer; each said envelope comprising a front ply; a back ply, and at least one line of hot melt pressure sensitive adhesive securing said front ply to said back ply, said adhesive being characterized in that after its open time has ended said adhesive remains very tacky and is capable of adhering to another ply of paper at any time that the paper makes contact with said adhesive.
Claim 8
Dependent Claim 83 words
A stacked array of interconnected envelopes disposed in layers of at least one envelope per layer; each said envelope comprising a front ply; a back ply, and at least one line of hot melt pressure sensitive adhesive securing said front ply to said back ply, said adhesive being characterized in that after its open time has ended said adhesive remains very tacky and is capable of adhering to another ply of paper at any time that the paper makes contact with said adhesive.
Claim 9
Dependent Claim 77 words
A tentless mailer assembly comprising a plurality of interconnected envelopes, each said envelope comprising a front ply, a back ply and at least one line of hot melt pressure sensitive adhesive securing said front ply to said back ply, said adhesive being characterized in that after its open time had ended, said adhesive remains very tacky and is capable of adhering to another ply of paper at any time that the paper makes contact with said adhesive.
Claim 10
Dependent Claim 77 words
A tentless mailer assembly comprising a plurality of interconnected envelopes, each said envelope comprising a front ply, a back ply and at least one line of hot melt pressure sensitive adhesive securing said front ply to said back ply, said adhesive being characterized in that after its open time had ended, said adhesive remains very tacky and is capable of adhering to another ply of paper at any time that the paper makes contact with said adhesive.
Claim 11
Dependent Claim 17 words
A tentless mailer assembly as set forth in claim 7 wherein said adhesive is a Fuller #HM-1089-B.
Claim 12
Dependent Claim 27 words
A tentless mailer assembly as set forth in claim 7 wherein each said envelope includes at least one insert between said front ply and said back ply.
Claim 13
Dependent Claim 103 words
In a continuous mailer assembly, the combination comprising a first ply having a plurality of transverse lines of weakening to define a series of envelope backs; at least one series of inserts between said plies, each said insert being disposed between a respective envelope back and an opposed envelope front and being peripherally free of said respective envelope back and front on at least one side thereof; a frame of cold adhesive between a respective back and front and peripherally about said insert therebetween; and at least one line of hot melt pressure sensitive adhesive between said plies and securing said plies together.
Claim 14
Dependent Claim 103 words
In a continuous mailer assembly, the combination comprising a first ply having a plurality of transverse lines of weakening to define a series of envelope backs; at least one series of inserts between said plies, each said insert being disposed between a respective envelope back and an opposed envelope front and being peripherally free of said respective envelope back and front on at least one side thereof; a frame of cold adhesive between a respective back and front and peripherally about said insert therebetween; and at least one line of hot melt pressure sensitive adhesive between said plies and securing said plies together.
Claim 15
Dependent Claim 77 words
A tentless mailer assembly comprising a plurality of interconnected envelopes, each said envelope comprising a front ply, a back ply, at least one insert between said front ply and said back ply, a frame of cold adhesive peripherally about said insert and securing said back ply to said front ply of each envelope to each other, and at least one line of Fuller #HM-1089-B hot melt pressure sensitive adhesive securing said front ply to said back ply.
Claim 16
Dependent Claim 77 words
A tentless mailer assembly comprising a plurality of interconnected envelopes, each said envelope comprising a front ply, a back ply, at least one insert between said front ply and said back ply, a frame of cold adhesive peripherally about said insert and securing said back ply to said front ply of each envelope to each other, and at least one line of Fuller #HM-1089-B hot melt pressure sensitive adhesive securing said front ply to said back ply.
