This invention relates generally to office accessories and, more particularly, to a file folder having an interior pocket for securing loose papers and retaining the folder in a closed position. The present invention is also directed to a method of using the file folder wherein the file folder is releaseably secured into a closed position and a method of manufacturing the file folder from a single sheet of material.
There are numerous types of file folders available for home or business organization and filing. The most common type of file folder is the standard card stock file folder into which papers may be placed having an index tab on one side of the folder for identification and organization purposes. While the standard file folder does assist in organizing one's papers, it does not secure the loose papers inside the file folder. Consequently, it is not uncommon for the papers to fall out of the file folder during insertion or removal of the file folder from a filing box or when carrying the file folder, particularly when there are a large number of papers in the file folder.
In order to secure loose papers within a file folder, it is well known to punch holes in the top or side of the loose papers and to secure the papers within the file folder by means of metal clasps and the like. Unfortunately, utilization of these known metal clasps requires destruction of the original quality and format of the papers because of the need to punch holes in the papers for insertion of the metal clasps.
Accordingly, the present invention provides several variations of file folders wherein the folder provides at least one interior pocket formed integrally with the file folder for retaining the papers and that enables the folder to be releaseably secured in a closed position. The file folder and pocket preferably being expandable to securely contain a large number of loose papers.
The present invention provides a file folder for securing loose papers inside the folder, wherein the folder comprises an integral pocket for holding the papers and for releaseably securing the folder in a closed position. The file folder is preferably constructed of a single elongate sheet of material comprising a first body section connected to a second body section along at least one central fold line. An overlap section is connected to the second body section along at least one pocket fold line. The overlap section is folded over a portion of the second body section along the at least one pocket fold line and secured in place to thereby form a pocket. Loose papers may be placed within the pocket with a portion of the papers positioned between the second body section and the overlap section. The first body section is folded over the second body section along the at least one central fold line and inserted into the pocket such that a portion of the second body section is positioned between the overlap section and any papers stored within the pocket. In this manner, the folder is releaseably secured in a closed position.
In a preferred embodiment, the sheet is cut to form an index tab extending adjacent the fold line between the body section and the overlap section. In this manner, when the overlap section is folded over the front of the body section, the index tab will remain extending outwardly from the body section.
In a preferred embodiment, the overlap section is secured in place using a pair of tabs extending outwardly from the sides of either the overlap section or the second body section. The tabs are folded over and secured to the opposing section from which the tabs extend (e.g. if the tabs extend outwardly from the sides of the second body section, the tabs are folded over and secured to the back of the overlap section) to thereby secure the overlap section in overlapping relationship with the second body section.
The present invention includes several embodiments wherein the file folder and the pockets may be expandable. The present invention also provides a method of manufacturing the file folders comprising die cutting the specific folder pattern from a single sheet of material, folding along specified fold lines, and adhering the securing tabs to form the pocket.

Front section 12 is generally rectangular in shape and defined by opposed side edges 8a, 8b, extending from front edge 10a to center fold section 16. Cut out notch 28 near the center of front edge 10a enables index tab 30 to be viewed when file folder 2 is assembled. Notch 28 is approximately ⅓ the length of front edge 10a. The corners of front edge 10a are preferably detail cut into a flattened “S” shape, as best shown in
Back section 14 is generally rectangular in shape and defined by opposed side edges 8a, 8b extending from center fold section 16 to pocket fold line 20. As shown in
Overlap section 18 is generally rectangular in shape defined by opposed side edges 8a, 8b, extending from pocket fold line 20 to back edge 10b. Outer corners of back section 14 and inner corners of overlap section 18—intersecting at pocket fold line 20—are preferably detail cut into a flattened “S” shape and are mirror images of each other to enable the corners to be flush when overlap section 18 is folded over back section 14 to form pocket 24. As shown in
Index tab 30 is located along pocket fold line 20 between back section 14 and overlap section 18 near the center of pocket fold line 20 and is approximately ⅓ the length of pocket fold line 20. Index tab 30 has 3 free edges 32a, 32b, 32c which are cut free from the sheet material to allow overlap section 18 to fold over onto the front of back section 14, thereby exposing index tab 30. Index tab 30 is integral with back section 14 at the base of index tab 30, and aligns with fold line 20. Index tab side edges 32a, 32c are detail cut as described above and have a flattened “S” shape. As shown in
A pair of pocket tabs 26a, 26b extend outwardly from back section 14 along side edges 8a, 8b in close proximity to fold line 20. As shown in
During assembly, overlap section 18 is folded along pocket fold line 20 over index tab 30 and onto the front of back section 14. Pocket tabs 26a, 26b are folded over the back of overlap section 18 along fold lines 34a, 34b and secured thereto with adhesive or other means known in the art, to form pocket 24. As shown in
As best shown in
A third embodiment of the present invention is depicted in
Pocket fold section 20 allows for expansion of the pocket 24 created by securing overlap section 18 and back section 14 together. The sides of pocket tabs 26a, 26b preferably taper inwardly toward the outer edge of the tabs such that the tabs are trapezoidal in shape with the side closest back section 14 extending inwardly at an angle (preferably approximately 15 degrees) greater than the angle of the side closest back edge 10b (preferably approximately 5 degrees). Pocket tabs 26a, 26b each have three scored fold lines 34a, 34a″, 34′″, 34b, 34b″, 34b′″ separating each pocket tab from overlap section 18 to accommodate the expansion capability of overlap section 18, and the pocket tabs 26a, 26b are sufficient in length to accommodate expansion of pocket 24. In addition, tapered fold lines 29a, 29b extending from the outer ends of pocket fold line 20′″ to opposed side edges 8a, 8b respectively also assist in expansion of the file folder.
As shown in
In assembly of the third embodiment, flap 36 folds over front of overlap section 18 at fold line 38 and is adhered thereto using adhesive 41 or other means known in the art. Overlap section 18 is then folded over the front of back section 14 and pocket tabs 26a, 26b are folded around the back of back section 14 at fold lines 34a, 34b and adhered thereto using adhesive 43 to form pocket 24, leaving open the edge formed by fold line 38 as the opening for the pocket.
Front section 112 is generally rectangular in shape defined by opposed side edges 108a, 108b extending from front edge 110a to fold line 116″″. Front edge 110a includes a cut out notch 128 near the longitudinal center of front edge 110a for viewing index tab 130 when file folder 102 is assembled. Notch 128 is approximately ⅓ the length of front edge 110a and approximately ½″ deep. The corners of front edge 110a are preferably rounded in shape, as shown in

Index tab 130 is located between overlap section 118 and back section 114, along pocket fold section 120. Index tab 130 is located near the longitudinal center of pocket fold section 120 and is approximately ⅓ the length of pocket fold section 120. Index tab 130 has 3 free edges 132a, 132b, 132c which are cut free from the sheet material to allow overlap section 118 to fold over index tab 130, thereby exposing index tab 130. Index tab 130 is integral with back section 114 at the base of index tab 130, and aligns with fold line 120′. As shown in
Looking to
During assembly, overlap section 118 is folded along pocket fold section 120 over index tab 130 and onto front of back section 114. Pocket tabs 126a, 126b are folded over back of back section 114 along tab fold sections 134a, 134b and secured thereto with adhesive or other means known in the art, forming expandable pocket 124 with curved edge 110b free for insertion of one or more sheets of paper 127 and for insertion of front section 112 to releaseably secure the file folder in the closed position.
It should be noted that the assembled size of folder 2, 102 may be any size adequate to accommodate the papers intended to be inserted in the pockets. Preferably, the assembled size of folder 2, 102 is sufficient to accommodate letter-sized papers measuring approximately 8½″×11″. It is also within the scope of the present invention for folder 2, 102 to be sized to accommodate legal-sized papers measuring approximately 8½″×12″ or oversized-papers having greater measurements.
Although specific combinations of an index tab, notch, pockets and pocket tabs have been described, it is within the scope of the present invention to utilize any number of combinations of the index tab, notch, pockets and pocket tabs heretofore described to create a wide variety of file folders. It should be understood that these elements may be of varying shapes, sizes and locations on the file folder without departing from the invention.
For all embodiments, outer corners of folder 2, 102 can be various shapes such as detail cut in a flattened “S” shape, rounded, square, angle-cut or virtually any shape that is easily manufactured. It should also be noted that the specific contour of the free corners of the front section 12, 112 may be virtually any shape, such as rounded, detail-cut, angled, square and the like.
It should be noted that for the fourth embodiment, the shape of the outer edge of overlap section 18, 118 could be a shape other than a concave curve. For example, the shape of the overlap section outer edge could be square, angled, straight, and the like. A curved profile, however, is preferred for ease of manufacture and to reduce the occurrence of paper cuts and ripping of the folder.
Although the index tab 30, 130 and corresponding notch 28, 128 have been described as being located in the approximate longitudinal center of folder 2, 102, it is also within the scope of the present invention for index tab 30, 130 and corresponding notch 28, 128 to be located closer towards one side of folder 2, 102.
In the manufacture of the present invention embodiments, a single sheet of material is die cut into the specific patterns described above and shown in the layout figures. Folder 2, 102 is then assembled by folding the respective overlap sections 18, 118 along the appropriate fold lines or scored sections and adhering the pocket tabs 26a, 26b, 126a, 126b to the folder—either on the back of back section 14, 114 and front section 12, 112 or the back of overlap sections 18, 118—to form pockets 24, 124. While the tabs are preferable secured using an adhesive, such as hot melt or water based adhesives, it should be understood that any other means known in the art for securing the tabs would be suitable for purposes of this invention, including the use of staples, ultrasonic welding, or rivets. In addition, it is within the scope of this invention to use a releasable securing means such as Velcro or to integrally form a securing means within the sheet of material such as by die cutting a notch and slot attachment means formed within the sheet material.
The file folder may be formed of any suitable sheet material, such as paper, card stock, Mylar, polypropylene or polyvinylchloride. The preferred sheet material is conventional file folder material such as card stock or polypropylene, and most preferably 11 point manila cardstock. White or colored cardstock could also be utilized.
