FIBER CONTAINER Filed April 21', 1926 Patented Jan. 14, 1930 UNITED STATES PATENT; oFricE PAUL F. BOEYE, OF

rnmn conrnimn Application filed April 21, 1926. Serial-110.103,!590.

This invention relates to fiber containers made from paper stock or other disintegrated, fibrousmaterial in sheet form and isparticularly adapted for shipping meat, such I as pork loins, or other irregularly shaped merchandise.

Many difliculties have been met with in wires for holding the flaps in closed position and Fig. 6 is a similar section showing an alternate arrangement offfastening for the normally free edges of the outer cover flaps. Asbest shown in Fig. 2,'my improved container has a main outer sheet of heavy fiber devising a fiber container which is durable j board 7, which is slotted and scored to form enough for practical use in the shipping of 1' such heavy goods. Qne, of the principal difficulties is in providing a fastening means for the closure of such containers, which will permit a certain amount of bulging or distortion of the container, and at. the same 16 time be sufficiently secure to prevent breakg thecover open in shipping or handling the boxes.

I have heretofore devised a body for such a container which meets themequirements of 2 strength. The means by which the body is rendered peculiarly strong are described and pointed out in my pending applications for patents, bearin Serial Nos. 743,276 and 76,415, filed on ctober 13, 1924, and Decemher 19, 1925, respectively.

The present invention comprises a -noveland eflicient arrangement of a cover or closure flap for such a container and means for preventing the breakingloose, shearing or opening of the cover during shipping, storing or handling of the boxes.

- The invention will be best understood by reference to the accompanying drawings, in

which Figure 1 is a perspective view of the finished container with the cover closed and secured; Fig. 2 is a plan view of the assembled blanks and reinforcing members laid flat and ready for folding in box form; Fig. 3 is a transverse section through the container showing the cover flap and fastenings therefor in openposition; Fig. 4 is a typical section illustrating the method of securing the liner to the outer walls of the box and reinforcing members; Fig. 5 is an enlarged detail in section, showing the arrangement the outer side panels 8, cover panels 9, bottom '10, a cover flap 11 and end flanges 12. End panels 13' are formed from separate sheets of the fiber board, which are secured to the outer surfaces of a pair of flanges 12 atthe ends of the bottom\1(l. These end panels l3 are scored as indicated in dotted s'r. PAUL, mmnrso'ra, assrenoa 'ro wnnnoarrarnn rnontrc'rs comm, A oonroaa'rron or'nnmnsoralines inv Fig. 2 to form outer cover flaps 14,

' adapted to be folded uponthe outer surface of the main cover panel 9 for fastening said cover in closed position.

Integral flanges 15 are formed by score lines 16 on the extremities of the flaps 14 and are adapted to be folded upon the inner surfaces of said flaps and secured thereon by means of wire staples 17 The folded flanges 15thus form hook-like members along the normally free edges of the flaps 14, adapted to receive wire retaining members 18, which are inserted to hold the flaps 14 in closed position, as hereinafter described.

Extending across-the sides 8, bottom l0 and main cover panel 9 near the ends of the box, is a pair of wires 19. The

wires

18 and 19 are secured upon the outer surfaces of the several panels by' staples 20 (see Fig. 4). The box is preferably lined by a sheet of corrugated board 21 extending over the inner surfaces of the cover 9, sides 8 and bottom 10,

and secured in place by the staples 20, as'

shown in Fig. 4.

In erecting the box, the end panels 13 are .first folded to a position perpendicular to the bottom panel 10. and then the sides 8 are raised to upright position andthe flanges 12 on said sides are secured to the outer sur- "faces of thepanels 13," as shown'in Fig, 1.

' cent to the inner surfaces of the end The goods to be shipped may now be placed in the box and the flap 11 turned inward at one side and the main cover panel 9 closed upon said flap, with the end flanges 12 adjaanels 13. The outer cover flaps 14 are then olded upon the cover panel 9 with the wires 19 upon the outer surfaces of said flaps.

The ends of each -wire 19 may now be secured one to the other by twisting and simultaneously drawing the wire tight about the box. Finally, the free portions of the wires 18 are inserted beneath the flaps 14 and drawn snugly into the angles formed between the flanges 15 and normally free mitted directly by the flaps 14 to the metal retaining members, 18. The portion of the wires 18 encircling the body of the box are offset toward the middle thereof from their portions engaging the flanges 15, so that when the wires are drawn tight and fastened, the flaps 14 will be pulled firmly inward from the -end of the container. The stitches 17 are applied to the reinforced edges of the flaps. r

In the alternate form of construction shown in Fig. 6, the normally free edges of the flaps 14 have the foldable flan es 15, but said flanges are secured in the orm of a loop across the edge ofthe flaps 14 by means of staples 23. With this form of box, the wires 18 for securing the free edges of the flaps 14. are inserted through the loop. so formed; It will be obvious that, if desired,

thestaples

17 and 23 may be omitted entirely, leaving the flanges 15 free to receive the wire 18 on. their upper surfaces.

The wires 19 further operate to clamp the ends ofthe cover panel inward, so that the ends of said panel are securely held in position to abut against the rigid panels 13 at each of the four vertical corners of the box.

-Thus, force's tending to warp or distort the be observed that in fiber containers of the class under consideration, there is a tendency of the wires to shear or cut the cover or closuremember, particularl during the handling of the filled containers. This is prevented in the present invention by reason of the fact that the wires are not in contact with the cover panel 9. The flaps 14 carry the shearing force of the wires 19 and the flanges 15 that of the wires 18.

Having described my inventionwhat I claim as new and desire to protect by Letters Patent is:

1. Ina fiber container the combination witha cover adapted to close the top of the container, of a retaining flap arranged to be folded over an end of said cover, a backwardly turned flange on the end of said flap,

a wire fastening member encircling the endv of the container and upon the outer surface of .said flap and a second wire fastening member encircling the container adjacent to the innerend of said flap and arranged to enga c said flange.

2. In a container for shipping heavy goods and formed from a plurality of separate blanks, a main body blank forming the bottom, two sides and a cover panel, a separate end panel secured to said sides and the bottom, a cover flap formed on said end panel to extend upon the-outer surface of sald cover panel, a wire retaining member secured to the outer surfaces of said sides and arranged to be extended across the outer ing two'sides, a'bottom and a cover panel, a

separate end blank secured to the sides and bottom and having a cover flap extending upon the outer surface of said cover pane a backwardly folded, reinforcing flange extending along the normally free'edge of said flap and a wire-retaining memberencirclmg the container and extending in the angle formed by said flange and flap to secure the free edge thereof in engagement with said cover.

4. In a container for shipping heavy goods and formed from a plurality of separate blanks, a main body blank forming the bottom, two sides and a cover panel, a separate end panel secured to said sides and the bottom, a cover flap formed on said and panel to extend upon the outer surface of said cover panel, a pair of wire retaining memhers secured to the outer surfaces of said sides and adapted to be extended entirely around the container to retain said flap upon the outer surface of said cover panel and a flange arranged on the normally free end of said flap to engage the portion of one of said wire members extending across the' cover panel, the other of said members ex.- tencling freely upon the outer surface of said flap to securely retain the same in contact with said rover panel. In testimony whereof, I have hereunto signed my name to this specification.
