Patented July 5, 1938 SHIPPING CONTAINER Orva 0. Nickerson, Fort Wayne, Ind., assignor to Fort Wayne Corrugated Paper Company, Fort Wayne, Ind., a corporation of Indiana Application October 5,

1 Claim.

My invention relates to improvements in shipping containers or packaging cases of the type primarily formed of fiber board or corrugated fiber board.

It is one of the objects of my invention to provide a shipping container which will have extreme rigidity, particularly when formed of fiber board, and which may be formed from a single blank of material. Such construction materially reduces the cost of production not only in the formation of the blank into a container but also in the cutting of the blank.

Furthermore, by forming the container from a single blank of material, greater rigidity and strength is given to the entire structure.

For the purpose of disclosing my invention, I have illustrated an embodiment thereof in the accompanying drawing, in which:

Fig. 1 is an end elevation of a container embodying my invention;

Fig. 2 is a transverse sectional view thereof;

Fig. 3 is a sectional view of the end wall;

Fig. 4 is a plan view of the blank;

Fig. 5 is a bottom plan of one of the cover corners; and

Fig. 6 is aperspective view showing particularly the intermediate breaks.

The case is made of an integral sheet of fiber board, corrugated fiber board or other suitable material and is formed from a single blank like that illustrated in Fig. 4. This blank is provided adjacent its longer ends with a pair of crease lines i and at right-angles thereto are provided a pair of crease lines 2 and a second pair of crease lines 3. A third pair of crease lines 4 is made at the opposite ends of the body blank. On continuations of the pair of crease lines 2 and be yond the crease lines I, the body is slit on its opposite sides as at 5-5 and 66. The body is also slit on each side for a short distance along the pair of crease lines 33 as at 'l-'l an 8-8. These slits meet pairs of slits 9-9 and l0l0 parallel with the crease lines l-l and extending beyond, toward the opposite ends of the blank, the crease lines 3-3. The ends of the blank are slit as at HH and i2-I2 on lines continuing the crease lines ll and apair of recess cuts on each edge such as i3|3 and I4--l4 are formed for a purpose which will more fully hereinafter appear. In addition to the above crease lines and slits, openings l5-l5 are formed in the body and indent openings l6-i6 and ll-l'l are formed in each edge.

The above creasing and slitting provides a blank containing a bottom portion [8, two end 1936, Serial No. 103,983

walls It, two side walls 20 and two cover members 2 I. Each of the cover members is provided with a side flap 22 and two end flaps 23. Furthermore, the two side walls are each provided at their opposite ends with a reinforcing flap 24 and a second reinforcing flap 25.

In folding the blank, the two side walls 20-20 are folded upwardly along the crease lines '2-2. The end flaps 24 of each side wall are then folded inwardly and the flaps 25 are folded downwardly upon the inwardly turned flaps 24. The end walls I 9 are then folded upwardly against the inturned flaps 24 and these parts all suitably stitched together by metallic stitching, metallic staples or other securing members.

The side flaps 22 on the cover members 2| are folded inwardly and the end flaps 23 likewise folded inwardly with the portions 25 of the end flaps bent to overlap the side flaps. These overlapping portions are likewise stitched together, the covers being adapted to hinge on the crease lines 3-3. It will be noted that each cover 2 l--2l is only half the width of the box and that when the parts are assembled, as above described, the recesses l3--i3 and I4l4 form downwardly extending slots in the upper edge of the side walls to receive the downturned edge flaps 22 of the cover with the end flaps 23 overlapping the outside of the ends. It will also be noted that the openings l5l5 form hand holds in the end walls of the cover and that the adjacent edges of the flaps 25 abut one another to form a reinforcement at the bottom of the slots l3 and above the hand hold openings.

These slots l3l3 in the end walls of the case are equal to the combined width of the side flaps 22 together with the turned tongues 26 of the cover members so that when the cover members are closed, the downturned edges thereof will readily take into the slots in the end walls.

In order to support the cover members 2! when folded into closed position and in order to also divide the box into two compartments, I provide a divider 21 having angularly turned flaps 28 lying parallel with the side panels 20-40 and adapted to be stitched thereto. The top of this divider 2'! is slotted as at 29 to receive the side flaps 22 on the cover members.

I claim as my invention:

A shipping container comprising bottom, side and end walls, the ends of the side walls being provided with integral flaps folded inwardly to substantially abut to form end walls, reinforcing flaps integral with said first-named flaps and folded back thereupon to reinforce the same, said reinforced flaps substantially abutting except at the upper portions thereof and being spaced apart at their upper portions to form downwardly extending slots, the ends of the bottom well being provided with integral flaps folded upwardl; to overlap said reinforced flaps further to reinforce the end walls, said end walls having hand holds extending through the. combined thickness of the side wall flaps, the reintorcing flaps, and the upturned bottom wall end flaps, and cover members hinged to the side walls and having downtumed side and end flanges, the side flanges being adapted to flt into the downwardly extending slots in the end walls when the cover members are closed.

ORVA O. NICKERSON.
