Sealed envelope assembly with locking pockets for free insert material

A stuffed, sealed envelope assembly comprising an envelope having front and back plies and at least one insert ply between said front and back plies, said envelope having internal adhesive means adjacent the peripheral edges of said front and back plies for uniting said front and back plies to form a generally sealed assembly, said adhesive means being spaced from the periphery of said insert ply so that said insert ply lies wholly within the enclosure of said envelope bounded by said adhesive means, said back ply having a plurality of spaced embossments located inwardly of said adhesive means and adjacent opposite peripheral edges of said insert ply, each of said embossments comprising a rectangular tab having a base portion integrally secured to said back ply along a substantially straight deflection line and a three-sided free portion cut from said back ply and deflected towards said front ply in substantial overlapping relationship with said insert ply so as to form a locking pocket therefor, the spacing between the innermost extremities of the free portion of opposed tabs being less than the corresponding dimension of said insert ply, said insert ply being maintained in desired registration within said envelope during machine processing by the locking pockets, said adhesive means being discontinuous, the discontinuities therein occurring at least adjacent said embossments, said front and back plies each including a line of weakening disposed inwardly of the deflection lines of said embossments along one side of said envelope whereby separation of the plies along the lines of weakening removes a marginal portion of the plies, frees the insert ply from the locking pockets on the removed marginal portion, and opens said envelope assembly.
