发明名称 Tabbed file folder with corner retention elements
摘要 Exemplary embodiments according to the present invention relate to a file comprising a cover member with front and back cover panels that are hinged to each other for movement between open and closed positions, wherein the cover panels in the closed position define an interior space configured and dimensioned for containing a plurality of stacked papers. The cover panels may have first and second corners disposed opposite from the hinge. At least one of the cover panels may comprise a tab portion extending away from the hinge and disposed between the corners. First and second elastic retention elements may each be secured to one of the cover panels. The first and second retention elements may be disposed and configured for looping around the first and second corners of the other cover panel, respectively, in the closed position for retaining the closed position.

主权项 1. A file system comprising a group of files, each file of the group of files comprising: a cover member comprising first and second cover panels that are hinged to each other at a living hinge for movement between open and closed positions, wherein the cover panels in the closed position define an interior space therebetween configured and dimensioned for containing a plurality of stacked papers, each cover panel having first and second corners disposed opposite from the hinge and defining a longitudinal edge length therebetween, the edge including first and second pass spaces disposed between the corners, wherein the first cover panel comprises a tab portion along the edge disposed between the corners outside the pass spaces and extending beyond the pass spaces of the cover panels in a direction away from the hinge; and first and second elastic retention elements, each having two ends that are mounted to the second cover panel in a position so that the elastic retention elements can reversibly be looped diagonally around the first and second corners of the cover panels, respectively, the retention elements crossing over the longitudinal edges at the pass spaces of both cover panels, in the closed position for retaining the closed position; wherein the pass spaces of each of the files of the group are disposed in a common location such that the pass spaces of the files are aligned with each other when the files are arranged in a stack, aligned in a common orientation with each other; and wherein the tabs of various of the files are disposed in different locations along the edge of each of the various files so that the tabs of the various files remain unobstructed by each other in the stack.
