when the pocket is filled with materials paper because the pocket panel and back panel are joined at the bottom 16 the space available for papers diminishes this would result in less paper space unless the convergence area extending upwardly from the bottom edge did not have an opening port 28 to relieve the pressure strain port 28 reduces these forces and greater capacity in the pocket in addition to packet 20 the preferred embodiment has additional pocket segments in fig1 two additional segments 30 32 are shown but there can be any reasonable number added one such segment 30 is shown in fig7 where the bottom edge 16 of the back panel is joined to the bottom edge 116 of segment 30 by a flexible bridging material 34 which is bonded to the surface of a bottom portion of 20 and 30 to create a flexible joint hinge this material 34 is preferably an adhesive tape or tyvek u00ae material which adheres permanently to both outer and inner surfaces at the bottom i e the back portion and pocket face and performs as a living hinge tape is preferably applied on both sides of the joint in the preferred embodiment the bottom edges 16 116 are not in contact but spaced apart to create a gusset section 36 which accommodates the expansion of the pockets when filled the living hinge or gusset is created during assembly by laying out the pockets 20 30 end to end on a flat jig but keeping them spaced apart while taping one side this gap creates the hinge when the folder is turned over for taping on the other side the two pieces of tape come into direct contact in the gap region to form a double thickness tape.
