3 Claims, 5 Drawing Figures 0 7 PATENTEUHARNIQH F/GZ 32 CUSHIONED SHIPPING FOLDER BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates generally to structures for enclosing books for movementthrough the mails, the structure being characterized by cells at each end thereof protecting the ends of the book therein.

2. The Prior Art Structures of this general kind are illustrated in Skaggs U.S. Pat.No. 3,l16,005 (Class 229/40).

SUMMARY OF THE INVENTION According to the present invention good protection is provided for a book during shipment by the provision of a cell disposed at each end of the shipping folder, the cell being characterized by an element extending in contact with one end of a book, a second element extending substantially in planar relationship with a wall of the folder, and an oblique member defining with the other elements a protective deformation resistant cell of generally triangular cross section.

THE DRAWING FIG. 1 is an isometric view of a closed shipping folder according to the present invention;

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

FIG. 3 is a perspective view showing steps in forming the folder of FIG. 1;

FIG. 4 is a view looking in the direction of the arrows 4-4 of FIG. 3;

FIG. 5 is a sectional view taken along the line 5-5 looking in the direction of the arrows.

The cushioned shipping folder according to the present invention is referred to generally by the reference numeral and is formed from a cut and scored blank 10A consisting of a pair of major parallel walls 11 and minor parallel walls 12 foldably interconnected along fold lines 13. An outer closure flap 14 is connected to one of the minor parallel walls 12 along a fold line 16, and a flap 14 is connected to the remote major wall 1 1 to form a tubular structure.

The folder according to the present invention is adapted to enclose a book B resting upon one of the major parallel walls 11 seen in FIG. 3, and closure structure is provided for each end of the folder l0, and comprises a first inner flap l9 and a second inner flap l7 foldably connected to each other along a fold line 18. First inner flap 19 is connected to a major parallel wall 11 by means of spaced

score lines

21 and 22, there being a score panel 23 therebetween. An interrupted cut line 24 flanks the two score panels 23.

As seen in FIG. 3, the inner flap 19 is folded to a position in facing relationship to the major parallel wall 11, and the second inner flap 17 is folded perpendicular to the first inner flap l9 and the major parallel wall 11 to lie against a book B seen in FIGS. 4 and 5.

a fold line 27.

With the book B in position between the second inner flaps 17, the other major panel 11 is brought over the book B. First outer flap 26 is folded to the position seen in FIGS. 3 and 4, and the second outer flap 28 is foldably connected as seen in the said figures and secured to the outer side of the first major wall 11, thereby creating an essentially triangular shaped cell protecting opposite ends of the book B. I

After the formation of the end cells seen more clearly with respect to FIGS. 4 and 5, the outer closure flap 14 is brought around and secured to the outside of panel 11. The ends of the closure flap 14 are mitered at 31 and contiguous ends of the second outer flaps are mitered as at 32, so that the flaps 14 and 28 may fit against each other.

Minor parallel wall 12 is likewise mitered at the ends 33 to fit snugly against the first outer flap 26 when the same is brought to the oblique position seen in FIGS. 4 and 5. v

I claim:

1. A cushioned shipping folder formed from a unitary blank of foldable paperboard or the like, comprising:

a. opposed pairs of major and minor parallel walls foldably interconnected to form a tubular structure;

b. an outer closure flap foldably connected to one of said parallel walls and secured to an adjacent parallel wall of said tubular structure;

c. a closure structure for each end of said tubular structure, said structure comprising:

i. a pair of first andsecond inner flaps foldably connected to each other with one of said flaps being foldably connected adjacent to one end of said major parallel wallsz- A. said first inner flap being folded to a position in facing relationship to said one major parallel wall;

8. said second inner flap being folded perpen- I dicularly with respect to said first inner flap and said one major parallel wall;

ii. a pair of first and second outer flaps foldably connected to each other with one of said outer flaps being foldably connected to one end of the other of said major parallel walls:

A. said first outer flap being folded to an oblique position in contact with edges of said inner flaps;

B. said second outer flap being folded along and secured to the first of said major parallel walls;

iii. said first and second pair of flaps defining a

Claims

1. A cushioned shipping folder formed from a unitary blank of foldable paperboard or the like, comprising: a. opposed pairs of major and minor parallel walls foldably interconnected to form a tubular structure; b. an outer closure flap foldably connected to one of said parallel walls and secured to an adjacent parallel wall of said tubular structure; c. a closure structure for each end of said tubular structure, said structure comprising: i. a pair of first and second inner flaps foldably connected to each other with one of said flaps being foldably connected adjacent to one end of said major parallel walls: A. said first inner flap being folded to a position in facing relationship to said one major parallel wall; B. said second inner flap being folded perpendicularly with respect to said first inner flap and said one major parallel wall; ii. a pair of first and second outer flaps foldably connected to each other with one of said outer flaps being foldably connected to one end of the other of said major parallel walls: A. said first outer flap being folded to an oblique position in contact with edges of said inner flaps; B. said second outer flap being folded along and secured to the first of said major parallel walls; iii. said first and second pair of flaps defining a deformation resistant cell of generally triangular cross section.

2. A folder according to claim 1 wherein said first inner flap is connected to said one major wall by spaced score lines defining score panels and cut lines alternating with said score panels to enable said first inner flap to be folded readily to position against said one major wall.

3. A folder according to claim 1 wherein said first inner flaps have a book or other flat object held therebetween.
