Mailer with oversized insert and method of making

Claim 2

A series of connected mailers comprising exterior plies constituting an envelope front and back each equipped with at least one superposed longitudinally extending control punch margin adjacent one longitudinal edge, a plurality of equally spaced lines of transverse perforation defining a series of envelopes each having the front and back plies connected along all four sides thereof, a plurality of insert plies within each envelope, at least one of said plies being transversely folded on itself, said folded ply being adhesively secured to the adjacent ply along only one longitudinal line, said longitudinal adhesive line being immediately adjacent said one control punch margin and inward thereof, and a longitudinally extending line of perforation in all of said plies inward or said longitudinal adhesive line to provide a detachable tub for separating said folded ply from said adjacent ply.

Claim 3

The structure of claim 1 in which said folded ply is overlapped adjacent the folded transverse edge thereof by said adjacent ply.

Claim 4

A series of connected mailers comprising exterior plies constituting an envelope front and back, a plurality of equally spaced lines of transverse perforation defining a series of envelopes each having the front and back plies connected along all four sides thereof, a plurality of insert plies within each envelope at least one of said plies being transversely folded on itself, said folded ply being both longitudinally and transversely folded.

Claim 5

A series of connected mailers comprising exterior plies constituting an envelope front and back, a plurality of equally spaced lines of transverse perforation defining a series of envelopes each having the front and back plies connected along all four sides thereof, a plurality of insert plies within each envelope at least one of said plies being transversely folded on itself, said folded ply being both longitudinally and transversely folded.

Claim 6

A series of connected mailers comprising exterior plies constituting an envelope front and back each equipped with at least one superposed longitudinally extending control punch margin adjacent one longitudinal edge, a plurality of equally spaced lines of transverse perforation defining a series of envelopes each having the front and back plies connected along all four sides thereof, a plurality of insert plies within each envelope at least one of said plies being longitudinally folded on itself, said folded ply being adhesively secured to the adjacent ply along only one longitudinal line, said longitudinal adhesive line being immediately adjacent said one control punch margin and inward thereof, and a longitudinally extending line of perforation in all of said plies inward of said longitudinal adhesive line to provide a detachable stub for separating said folded ply from said adjacent ply, the fold in said folded ply being positioned adjacent the other of said longitudinal edges.

Claim 7

A series of connected mailers comprising exterior plies constituting an envelope front and back each equipped with at least one superposed longitudinally extending control punch margin adjacent one longitudinal edge, a plurality of equally spaced lines of transverse perforation defining a series of envelopes each having the front and back plies connected along all four sides thereof, a plurality of insert plies within each envelope at least one of said plies being longitudinally folded on itself, said folded ply being adhesively secured to the adjacent ply along only one longitudinal line, said longitudinal adhesive line being immediately adjacent said one control punch margin and inward thereof, and a longitudinally extending line of perforation in all of said plies inward of said longitudinal adhesive line to provide a detachable stub for separating said folded ply from said adjacent ply, the fold in said folded ply being positioned adjacent the other of said longitudinal edges.

Claim 8

The structure of claim 4 in which said envelope includes two longitudinally folded plies, one within the other.
