## Title
Multiple pocket folders and method of manufacture

## Abstract

Pocket folders for holding documents and method of manufacture are shown in various embodiments. In one embodiment, a single unitary blank is cut and folded into a double slot folder without the need to glue pieces together. The blank is cut to have adjacent panels and an extension panel cut so that they are folded one panel atop the other to form a unitary pocket folder with two pockets. In a second embodiment, a two pocket folder is formed likewise with three adjacent panels as in the first embodiment, but the extension panel is then wrapped with a back panel to create a second pocket which can be folded outwardly.

## Background
BACKGROUND
1. Field of the Disclosure
The present invention is directed to folders for use in connection with storage of documents.
2. Description of the Related Art
Folders and more particularly pocket folders are useful for holding documents permanently or temporarily. For competitive reasons they must be made inexpensively, but without sacrificing durability and functionality. Most folders are designed with a single pocket because that is the most inexpensive form to make, but there has been a long felt need for multi-pocket folders but which can still provide durability and low cost. The present disclosure provides such a solution.

DETAILED DESCRIPTION
This disclosure describes file folders, sometimes known as pocket folders, in various related embodiments.
The following is an overview: FIGS. 1-9 disclose a double pocket folder whereas FIGS. 10-19 illustrate a variant diagonal cut to expose more of the documents stored therein. FIGS. 20-27 illustrate a double pocket folder with a fold out pocket. Several variants thereof are disclosed. To the extent that parts are the same or similar, the same reference number will be used or an increment thereof, such as 10 and 110.
A method of manufacture is also disclosed by the drawings and description.
File folder 10 in FIGS. 1-9 show a unitary blank with a front extension panel 12, back/first panel 14 and second panel 14. The extension panel 12 extending laterally from the back panel 14 along a fold line 20. Extension panel 12 extends from panel 14 along fold line 22, thumb notches 24 may be provided. Panel 12 which becomes the front panel when folded, includes a pair of flaps 30, 32 which complete the folder when the flaps are adhered to the back panel as shown in FIG. 3. Flap 30 is an extension of the front panel along the longitudinal edge and 32 is an extension along the lateral edge along fold lines 34, 26. Notch 38 in panel 16 adjacent the fold line 20 is cut into the lateral edge of the panel to provide expansion space for the pocket which is formed. It is extended from fold line 20 upwardly toward the distal edge. The notch is typically of 2-5 cm in length and 2-3 mm deep or roughly just exceeding the height of flap 30 and prevents puckering and binding.
In order to insure that there will be tab/writing space 40, 42, 44 visible at the top (distal) edge of each panel, it is preferably to offset/cut away a portion of panel 12 at its top tab edge 42. This offset 48 provides exposure of the tab section 40 of panel 16 by being shorter than height 54 in panel 14. Likewise panel 16 must have its lateral height 50 shorter than both heights 52 and 54 in order that all tabs areas are exposed. The corner 46 of panel 12 is cut an angle to reduce interference between the tabs 30, 32.
The method of manufacturer is to cut a single unitary blank. Unitary means that the material is a continuous web, not joined from separate pieces. The preferred cut pattern is as follows: a back panel with first and second sides having bottom edges and separated by a central fold line, the first side including a foldable extension panel which extends beyond the bottom edge, the extension forms the front panel of a foldable pocket and has lateral flaps, when formed to make a folder. The second panel 16 is folded upwarded along fold line 20 and then the extension panel 12 is folded onto the second panel 16 and flaps 32/30 (or just 30 if an open side is desire) are affixed to the back panel 14 thereby forming two pockets with a single unitary blank.
The embodiment shown in FIGS. 10-19 is similar to the previous embodiment and the parts are indicated with numerals incremented 100 and will not be repeated for brevity.
The folder 110 from which the blank differs in that the top edges 142, 144 are cut at an angle to expose more of the surface of the documents which may be stored in the pocket. This diagonal or slash cut can be as shown rising from left to right or right to left. Otherwise, the unitary nature of the blank and method of manufacture is the same as the prior embodiment.
FIGS. 20-27 illustrate an alternative construction and method of making a multiple pocket file folder. In this embodiment, a folder 210 has a front panel 212 and back panel 212, separated by a fold line 222.
A pocket unit is attached to the bottom edge 234 by in various forms as shown in the figures. In FIGS. 20 and 22, the pocket unit 215 is a separate non unitary pocket having a back panel 217 which is affixed to panel 214 by tab extension 219 which extends from the bottom portion of panel 214. Note that tab 291 is preferably narrower than the width of panel 214.
To create a pocket, front panel 221 with tabs 223 is applied to the front of panel 217 and tabs 223 are affixed to the back of panel 217, though the reverse configuration with tabs in front is also possible.
FIG. 21 is a similar embodiment except that the back panel 214 has a unitary extension 214a which forms a panel of pocket 215.
FIG. 23 illustrates a completely unitary embodiment made from a single blank/web of material. Panel 214 has a first extension 214a extending longitudinally from the bottom thereof and lateral thereto a second extension 214b with tab 223. The pocket is formed by folding panel 214b onto 214a along fold line 231, then tab 223 is folded and affixed to 214a along fold line 233 and finally to formed pocket may be folded up along line 235.
Note that there is preferably a notch 241 laterally into panel 214a adjacent fold line 235, to provide expansion space within the pocket. Likewise, panel 214b can be folded in front of panel 214a or behind it. If in front, then its height will be lower than that of 214a by the cut down area 243 to allow visibility of documents therein.
FIG. 24 shows the folder with the pocket folded up. FIG. 25 is like FIG. 21 but in a mirror image configuration and with a top tab 247. FIG. 26 is a view from the back on an end tab 249 version. FIG. 27 is a perspective view of the pocket.
The above description and its applications as set forth herein is illustrative and is not intended to limit the scope of the invention. Variations and modifications of the embodiments disclosed herein are possible and practical alternatives to and equivalents of the various elements of the embodiments would be understood to those of ordinary skill in the art upon study of this patent document. These and other variations and modifications of the embodiments disclosed herein may be made without departing from the scope and spirit of the invention.
