发明名称 High capacity pocket file folder
摘要 A pocket folder with increased document capacity and method of manufacturing same is disclosed. The folder has two cover panels 14-16, joined along a longitudinal joint or score line, a pair of pocket flaps 40a-40b and a top flap 70. Top flap 70 folds along a score line 72a-72b and a midline score 74 and a plurality of parallel scores 78 to accommodate expansion. At the pockets, a v-shaped notch 52 between the pockets prevents bunching and a circular cut away 90a-90b provides greater access to the documents.

主权项 1. A method of minimizing waste in forming making a blank of web material into a plurality of pocket folders each having a pair of pockets on either side of a center fold line and having a retainer flap, comprising the steps of: a. cutting and scoring a blank having left and right edges and left and right portions and upper and bottom edges and a central longitudinal score forming a center line defining left and right portions and a lateral score line orthogonal to the central longitudinal score line located a predetermined distance from the bottom of the blank defining a fold line to create left and right pockets; b. defining a portion of the blank at its top edge orthogonal to the central score line, a semicircular protrusion foldable into a flap , and defining an upper longitudinal edge of the blank, excluding the protrusion; c. scoring said blank along the upper edge to define a fold line between the protrusion and the upper edge; d. cutting the blank into first and second identical blanks, each forming a separate folder, the cutting occurring along line parallel with the upper and bottom edged except adjacent the central fold line where the cut line follows a semicircle on either side of said fold line, thereby forming said flap protrusion on said top edge and a semicircular recess in said bottom edge, wherein said flap protrusion and said semicircular recess have identical curvatures, so that there is no waste material therebetween; e. scoring a protrusion fold line in said flap protrusion, said protrusion fold line being co-axial with said blank fold line; f. cutting a v-shaped notch into the bottom edge from at the central score line to said predetermined distance from the bottom-edge; g. folding along the said blank along said lateral score line to form a pair of side by side pockets; h. folding said protrusion along said protrusion flap fold line to create a top retaining flap; i. cutting away a section of the blank on the left and right portions adjacent the bottom of the blank and side scoring the blank on the left and right portions longitudinally spaced a predetermined distance from the left and right edges; j. folding said blank along said at said side scoring, and k. affixing said side scoring portions to said pockets.
