Stair step portfolio file with front pocket and method for manufacturing same

A frontal pocket on a file folder, the file folder having a front-most panel, itself having a top edge and interior and exterior faces, the pocket comprising:

• a planar blank having a plurality of score lines and folds thereby creating an insert pocket unit including;
• a first portion extending downwardly and being affixed onto at least a portion of said interior face of said front-most panel and being folded over said top edge and extending downwardly and being affixed to said exterior face, to form one sidewall of the frontal pocket;
• said first portion having lateral edges on the portion affixed to said exterior face, and first retainer flaps extending from said lateral edges;
• a second portion extending lateral and outwardly from said exterior face a predetermined distance to form the bottom of the frontal pocket;
• a third generally vertical portion extending generally upward line from said second portion and generally parallel and spaced apart from said first portion to form a second sidewall of the frontal pocket, said third portion having lateral edges and second retainer flaps extending therefrom
• and wherein the front-most panel of the folder includes retainer flaps extending from lateral sides of said front-most panel, said retainer flaps being affixed to said first portion.

A method of making and retaining a front-most pocket to be affixed to a file folder, comprising:

• a file folder having a front panel having a top edge and interior and exterior faces of predefined length and width and lateral sides, a pair of retainer flaps extending from said lateral sides;
• a frontal pocket being formed by the steps of:
• cutting a planar blank web material into a shape having first, second and third collinear segment portions with scored fold lines between the segment portions;
• the first segment portion being cut to be no wider than the width of the interior face and no longer than the length of the interior face;
• cutting the blank have retaining flaps extending laterally from said first and second portions;
• cutting the blank to have closure flaps extending from lateral edges of said first and third portions,
• folding the blank so that said first and third portions are generally parallel and spaced apart from each other to form a gap therebetween with said second panel spanning said gap,
• folding the closure flaps toward each other and to overlie each other, said closure flaps thereby forming sidewalls of the pocket
• adhering the first portion to said exterior face and folding a part of said first portion over said interior face and adhering it thereto, thereby creating a cantilevered attachment between the folder and the pocket;
• adhering said retaining flaps of said file folder to said first portion.
