No. 260,913 Filed June 8, 1972 SUMMARY OF THE INVENTION The cushioned shipping folder according to the invention herein is characterized by a central panel having crushed areas which cooperate with crushed areas on tuck-in and closing flaps and defining with major flaps protective cells for margins of a book or the like. The crushed areas of both the tuck-in flaps and the central panel provide a planar surface supporting allareas of the flat article.

THE DRAWINGS FIG. l is a perspective view showing a cushioned shipping folder according to one embodiment of the invention;

FIG. 2 is a plan view of a cut and scored blank for forming the folder according to FIG. 1;

FIG. 3 is a perspective view showing the steps in folding the blank of FIG. 2 about a book;

FIG. 4 is a sectional view taken along the line 4-4 of FIG. I. looking in the direction of the arrows;

FIG. 5 is a perspective view showing a folder according to another embodiment of the invention;

FIG. 6 is a plan view of a cut and scored blank for forming the folder seen in FIG. 5; and

FIG. 7 is an isometric view showing the manner in which the blank of FIG. 6 may be folded about a book or the like.

The improved cushioned shipping folder according to one embodiment of the invention is referred to generally by the reference numeral 10, and it is formed from a blank 10A of cut and scored paperboard or the like. Blank 10A comprises arectangular shaped central panel 11 having crushed areas 12 extending along opposite margins thereof. Opposed major flaps 13 and minor flaps 14 are foldably connected to each other along a fold line 16, minor flap 14 being connected to an opposed margin of the central panel 11 along a score line 17. The minor flaps 14 are folded against opposed ends of a flat article such as a book B seen in FIG. 4, and the major flaps 13 are folded to position overlying the flat article B.

Each of the major flaps 13 is provided with opposed cell forming flaps 18, each being defined by spaced cut lines 19 extending transversely to the edge 23 of each major flap 13 and by parallel fold lines 21 and 24. Each of the cell forming flaps 18 is foldably connected to a tuck-in flap 22 hingedly connected to the cell forming flap 18 by the fold line'24. Each tuck flap 22 has a crushed area thereon as shown by the shading. Each of the cell forming flaps 18 is folded to position against other margins of the flat article B, and the tuck flaps 22 are folded to position beneath article B and in lapping relationship with the crushed areas 12 of the central panel 11 to provide a planar support for the book B on all bottom areas of such article.

It will be noted from FIG. 4 that the thickness of the crushed areas of the tuck flap 22 and the thickness of the crushed area 12 in central panel 11 are such as to give a combined thickness equal to the thickness of the uncrushed central panel-l1.

Opposite margins of the central panel 11 are provided with a closing flap 26 foldably connected to the central panel 11 along a score line'27. Each of such closing flaps 26 is adapted to bear against the'edges 23 of the. major flaps 13 to thereby create opposed cells between the cell forming flaps 18 and the closing flaps 26 as seen more clearly in FIG. 3.

Each of the closing flaps 26 has a closure panel 28 foldably connected thereto along a fold line 29, and after the assembly seen in FIG. 3 is complete, the-closure panels 28 are brought over the major flaps 13, the closing being completed by pressure sensitive tape T or the like as seen in FIG. 1.

Referring now to FIGS. 5 to 7 of the drawings, there is'shown a second embodiment of the invention denoted generally by the reference numeral 30 and formed from a cut and scored blank 30A of paperboard or the like. Components of the structure seen in FIG. 5 similar to those of FIG. 1 are denoted by the same reference numeral, and parts of the description relating to FIG. 1 neednot be repeated for the structure of FIG. 5. The structures of FIG. 1 and FIG. 5 differ with respect to their closure panels, and it may be noted from FIG. 6 that there is but one closure panel 28, it being of a dimension as to correspond to the area of the major flaps l3.

Closure panel 28 of FIG. 6 has an outer closure flap 31 foldably connected thereto along a fold line 32. A locking tab 33 is foldably connected along a fold line 34 to the distal edge of the flap 31 and is provided with locking shoulder 37. The locking tab 33 is adapted to enter an aperture 36 formed in the opposite closing flap 26, the completed assembly being as seen in FIG. 5.
