Description:
BACKGROUND OF THE INVENTION
This invention relates to portfolios, and more particularly to an inexpensive, versatile, twin pocket portfolio and file folder formed from a single, integral, die-cut blank.
Examples of simple and inexpensive portfolios assembled from one or more pieces of paper or cardboard may be found in U.S. Pat. Nos. 1,683,996, 1,859,631, 2,103,203, 2,390,864, 3,070,279, 3,129,872 and 3,516,599. See also U.S. Pat. Nos. 2,226,837, 2,345,793, 2,633,848 and
3,308,942 . These folders provide one or more interior pockets of various sizes and shapes, and in some cases score lines in the inner portfolio walls provide a multiplicity of openings into the pockets. However, notwithstandi ng the efforts which have been made to maximize the usefulness of such one-piece portfolios, the outer surfaces of these portfolios have rarely been used except as portfolio covers. U.S. Pat. No. 2,390,864 discloses slits and slots around the edges of the outer rear wall of the portfolio for supporting a piece of paper, but finds no other use for the outer walls of the portfolio.
SUMMARY OF THE INVENTION
Briefly, the present invention provides a single, one-piece, integral blank which is cut and folded to provide a twin pocket portfolio and file folder having pockets for storage on the interior and easily accessible file folder storage on the exterior.
A front outer panel is hingedly connected to a rear outer panel, and a front inner panel is similarly hingedly connected to a rear inner panel. The inner panels are connected to their respective outer panels by a bottom fold line and folded into facing relationship with their outer panels. The panels are then joined along the edges opposite their hinge lines to form front and rear pockets which are open at the top.
The inner panels have slits to provide access to their respective pockets for reception, filing, storage and support therein of papers, notepads, envelopes, and so on.
The front and rear outer panels are shorter than the front and rear inner panels so that the pockets formed by these panels provide exterior front and rear file folders with identification tabs.
Thus the single blank of the present invention provides portfolio pockets on the inside of the portfolio and file folders on the outside of the portfolio. A maximum of utility and flexibility results from an uncomplicated and inexpensive single-piece construction.
It is therefore an object of the present invention to provide a twin pocket portfolio and twin pocket file folder formed from a single, integral blank of material; a portfolio and file folder in which the outer panels or surfaces are utilized as well as the inner panels; which may conveniently support a removable and replaceable notepad therein; which is simple and economical to fabricate; and which is sturdy, durable and readily suited to inexpensive mass production.
Other objects and advantages of the invention will be apparent from the following description, the accompanying drawings, and the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 illustrates the single, unitary blank 10 from which the twin pocket portfolio and file folder 11 (FIG. 7) is formed. As may be seen, blank 10 is a one-piece blank which includes a front outer panel 12 and a rear outer panel 13 joined by a first center fold line 14. A front inner panel 17 is connected to the front outer panel 12 along a first bottom fold line 18. Bottom fold line 18 runs along the edge of the front outer panel which is adjacent and intersects the edge of panel 12 defined by the first center fold line 14. similarly, a rear inner panel 21 is connected to the rear outer panel 13 along a second bottom fold line 22, and to the front inner panel 17 along a second center fold line 24. The second bottom fold line 22 forms an extension of the first bottom fold line 18, and the second center fold line 24 forms a similar extension of the first center fold line 14.
A front flap 26 is joined to the front outer panel 12 on a front flap fold line 27 on the edge of panel 12 opposite the first center fold line 14. A rear flap 28 is similarly joined by a rear flap fold line 29 to the edge of the rear outer panel 13 opposite the first center fold line 14.
The front inner panel 17 is partially cut through by a diagonal slit 31 and the rear inner panel 21 is partially cut through by a transverse slit 32. The ends of slits 31 and 32 include round cutouts 34 to resist tearing of the portfolio material at the ends of slits 31 and 32.
The edges of the front and rear outer panels 12 and 13 opposite the bottom fold lines 18 and 22 include respective integral index tabs 36 and 37, as well as generally arcuate recesses or cutouts 38 and 39, for reasons explained more fully below.
The blank 10 is formed into the twin pocket portfolio and file folder 11 by folding the inner panels 17 and 21 along their respective bottom fold lines 18 and 22 to bring the inner panels into facing relationship with their respective front and rear outer panels 12 and 13. The front and rear flaps 26 and 28 are then folded on lines 27 and 29 around the inner panels 17 and 21 (FIGS. 3 and 4) and attached to the inner panels by adhesive lines 41 and 42 on flaps 26 and 28. The flaps 26 and 28 and adhesive lines 41 and 42 thus join the inner panels to their respective outer panels along the edges opposite the center fold lines 14 and 24.
Next the panels are folded on the first and second center fold lines 14 and 24 to bring the front outer panel 17 adjacent the rear inner panel 21. The center fold lines 14 and 24 serve as hinges for the portfolio, hingedly joining their respective outer panels and inner panels. An inside elongated cutout 45 on the second center fold line 24 adjacent and extending away from the bottom fold lines 18 and 22 promotes the proper and desired folding of the center fold lines 14 and 24 and helps to prevent tenting thereof.
The blank 10 is thus folded twice and adhered at the flaps 26 and 28 to form a front pocket 50 between front outer and inner panels 12 and 17, and a rear pocket 55 between rear outer and inner panels 13 and 21. The slits 31 and 32 then provide access to these pockets from within the portfolio, for reception, filing, storage and support therein of papers, notepads, envelopes, and so on. For example, a pad 58 of notepaper (FIG. 4) may be conveniently supported through transverse slit 32 in panel 21.
The front and rear pockets 50 and 55 are open at the top, and the front and rear outer panels 12 and 13 are shorter than the inner panels 17 and 21 (FIG. 7). That is, the front and rear inner panels are longer along the second center fold line 24 than the front and rear outer panels along the first center fold line 14. These panels thus define respective exterior front and exterior rear file folders 60 and 65, with the shorter front and rear outer panels 12 and 13 providing ready access to the file folders 60 and 65. The utility of the file folders 60 and 65 is further enhanced by the cutouts 38 and 39 which facilitate access to the file folders, and by the integral index tabs 36 and 37 for indexing the file folders, as desired.
As may be seen, therefore, the present invention provides numerous advantages. It is inexpensive and uncomplicated. It is formed from a single, one-piece blank of material which may be die-cut and assembled on conventional mass production machinery. It may be formed of any suitable material, such as cardboard. In addition to providing the utility and convenience of a multi-pocket portfolio, the present invention provides integral, exterior file folders without requiring any additional, separate pieces of material, or any additional assembly procedures.
While the form of apparatus herein described constitutes a preferred embodiment of this invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention.
This invention relates to portfolios, and more particularly to an inexpensive, versatile, twin pocket portfolio and file folder formed from a single, integral, die-cut blank.
Examples of simple and inexpensive portfolios assembled from one or more pieces of paper or cardboard may be found in U.S. Pat. Nos. 1,683,996, 1,859,631, 2,103,203, 2,390,864, 3,070,279, 3,129,872 and 3,516,599. See also U.S. Pat. Nos. 2,226,837, 2,345,793, 2,633,848 and
3,308,942 . These folders provide one or more interior pockets of various sizes and shapes, and in some cases score lines in the inner portfolio walls provide a multiplicity of openings into the pockets. However, notwithstandi ng the efforts which have been made to maximize the usefulness of such one-piece portfolios, the outer surfaces of these portfolios have rarely been used except as portfolio covers. U.S. Pat. No. 2,390,864 discloses slits and slots around the edges of the outer rear wall of the portfolio for supporting a piece of paper, but finds no other use for the outer walls of the portfolio.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 illustrates the single, unitary blank 10 from which the twin pocket portfolio and file folder 11 (FIG. 7) is formed. As may be seen, blank 10 is a one-piece blank which includes a front outer panel 12 and a rear outer panel 13 joined by a first center fold line 14. A front inner panel 17 is connected to the front outer panel 12 along a first bottom fold line 18. Bottom fold line 18 runs along the edge of the front outer panel which is adjacent and intersects the edge of panel 12 defined by the first center fold line 14. similarly, a rear inner panel 21 is connected to the rear outer panel 13 along a second bottom fold line 22, and to the front inner panel 17 along a second center fold line 24. The second bottom fold line 22 forms an extension of the first bottom fold line 18, and the second center fold line 24 forms a similar extension of the first center fold line 14.
A front flap 26 is joined to the front outer panel 12 on a front flap fold line 27 on the edge of panel 12 opposite the first center fold line 14. A rear flap 28 is similarly joined by a rear flap fold line 29 to the edge of the rear outer panel 13 opposite the first center fold line 14.
The front inner panel 17 is partially cut through by a diagonal slit 31 and the rear inner panel 21 is partially cut through by a transverse slit 32. The ends of slits 31 and 32 include round cutouts 34 to resist tearing of the portfolio material at the ends of slits 31 and 32.
The edges of the front and rear outer panels 12 and 13 opposite the bottom fold lines 18 and 22 include respective integral index tabs 36 and 37, as well as generally arcuate recesses or cutouts 38 and 39, for reasons explained more fully below.
The blank 10 is formed into the twin pocket portfolio and file folder 11 by folding the inner panels 17 and 21 along their respective bottom fold lines 18 and 22 to bring the inner panels into facing relationship with their respective front and rear outer panels 12 and 13. The front and rear flaps 26 and 28 are then folded on lines 27 and 29 around the inner panels 17 and 21 (FIGS. 3 and 4) and attached to the inner panels by adhesive lines 41 and 42 on flaps 26 and 28. The flaps 26 and 28 and adhesive lines 41 and 42 thus join the inner panels to their respective outer panels along the edges opposite the center fold lines 14 and 24.
Next the panels are folded on the first and second center fold lines 14 and 24 to bring the front outer panel 17 adjacent the rear inner panel 21. The center fold lines 14 and 24 serve as hinges for the portfolio, hingedly joining their respective outer panels and inner panels. An inside elongated cutout 45 on the second center fold line 24 adjacent and extending away from the bottom fold lines 18 and 22 promotes the proper and desired folding of the center fold lines 14 and 24 and helps to prevent tenting thereof.
The blank 10 is thus folded twice and adhered at the flaps 26 and 28 to form a front pocket 50 between front outer and inner panels 12 and 17, and a rear pocket 55 between rear outer and inner panels 13 and 21. The slits 31 and 32 then provide access to these pockets from within the portfolio, for reception, filing, storage and support therein of papers, notepads, envelopes, and so on. For example, a pad 58 of notepaper (FIG. 4) may be conveniently supported through transverse slit 32 in panel 21.
The front and rear pockets 50 and 55 are open at the top, and the front and rear outer panels 12 and 13 are shorter than the inner panels 17 and 21 (FIG. 7). That is, the front and rear inner panels are longer along the second center fold line 24 than the front and rear outer panels along the first center fold line 14. These panels thus define respective exterior front and exterior rear file folders 60 and 65, with the shorter front and rear outer panels 12 and 13 providing ready access to the file folders 60 and 65. The utility of the file folders 60 and 65 is further enhanced by the cutouts 38 and 39 which facilitate access to the file folders, and by the integral index tabs 36 and 37 for indexing the file folders, as desired.
As may be seen, therefore, the present invention provides numerous advantages. It is inexpensive and uncomplicated. It is formed from a single, one-piece blank of material which may be die-cut and assembled on conventional mass production machinery. It may be formed of any suitable material, such as cardboard. In addition to providing the utility and convenience of a multi-pocket portfolio, the present invention provides integral, exterior file folders without requiring any additional, separate pieces of material, or any additional assembly procedures.
While the form of apparatus herein described constitutes a preferred embodiment of this invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention.
