BOX.

Application led April 13, 1922. Serial No. 552,342.

This invention relatesto improvements in boxes made of fibre or paper board or the like and consists of the matters hereinafter described and more particularly pointed out in the appended claim.

The object of the invention'is to provide a collapsible fibre or paper board box capable A of top loading which may be, manufactured at a minimum cost of labor and material and which has a top closure that may be nailed shut, so that it can be easily opened by the use of the familiar nail puller, when the contents of the box are to be inspected, and again nailed in closed position.

The advantages of the invention will appear as I proceed with my specification.

In the drawings: Figure 1 is a perspective view of the improved ,box; Figure 2 Vis a partial top plan view of the box with the top closures turned back 1n open position;

Figure 3 is a transverse, vertical cross section of the box in a plane indicated by the line 3 3 of Fig. 1;

Figure 4 is a longitudinal, vertical section of the box in a plane indicated by the line 4-4 of Fig. 1;

Figure 5 is a plan view of the blank to form the box;

Figure 6 is a perspective View of a wood bar included in the box structure;

Figure 7 is a partial perspective view of a corner of the box.

Referring now to that embodiment of the invention illustrated in the accompanying drawings 10 indicates the body of the box, which, as shown, is somewhat elongated and is wider than it is deep, although these proportions may be varied to meet the requirements of the box. 11, 11 indicate the sides of the box; 12 the bottom of the box; 13, 13 the ends of the box; and 14 indicates the top closure, which in this case consists of two flaps 14a, 14, each somewhat wider than one-half the width of the box, so that they overlap, when in closed relation, as clearly appears in'Figures 1 and 3.

The box in its preferred form is made from a single blank of paper (see Fig. 5) which is cut and creased to fold into box form. The main length of the blank is creased along transverse parallel lines 15 to provide the bottom 12, the

sides

11, 11

and the two cover iiaps 1 4, 14a,-all of which are laid out side by side in proper order, with their lengths extending transversely of the blank and with the flaps 14, 14L1 at the ends of the blank. 16, 16 indicate parallel, spaced, crease lines, extending lengthwise of the blank and defining the ends of the

sides

11, 11 and ofthe bottom 12. The flaps 14, 142t extend at their ends 14, 14b somewhat beyond the

longitudinal crease lines

16, 16, which terminate at the

transverse crease lines

15, 15 upon which the fiaps14, 14a are designed to fold. The blank has lateral extensions intermediate the flaps 14a, which yextensions are cut to define end flap extensions 11a, 11a on each of the box side-forming `

parts

11, 11 of the blank and end flap extensions 12a, 12El on the box 'bottom-forming part 12 of the blank. When the blank is folded into box form, said flap extensions provide the ends of the box,- the flap extensions 12a being each of the width and depth of the box andthe flap extensions 11a being of the depth of the box along the crease lines 16, but having a length at right angles to said crease lines somewhat greater than the width of the box so that they will overlap, when folded, one upon the other, as appears in Fig. 3.'

The box is s et up by folding the blank to bring the

sides

11, 11 into a position vat right angles to the bottom 12, whereupon the side end flaps 11, 11a are folded one upon the other and the bottom end flap 12a is folded up outside the said side end flaps. The several flaps named are secured in this yposition-in which they form the end walls of the boxe-by transverse pairs of

wood cleats

17, 17 Thesaid wood cleats are of a length substantially` equal to the width of the box and are preferably wider or" deeper than they are thick. Each pair of wood cleats is attached, -by stapling Oor otherwise, to the several end flap extensions, forming the end of the box, with said end flaps embraced between them and with the Ctop edges of the cleats, providing a top surface against which the top Haps 14, 14a may be closed, as shown4 iaps is manifest,said end extensions overl lying and closing upon the outside end cleats 17, as is shown in Fig. 7.

After the box is' loaded throughits open top, the top closure iaps 14a are folded down, one overlapping the other, upon the top edges of the ends of the box comprising the

wood cleats

17, 17 andend flap extensions of the sides and bottom-respectively, 11a, 11 and la-embraced between them. Said tov closure flaps are then nailed at their en s to the ends of the box thus comprised,-the nails readily taking into the composite nailing edges of the box,-pref erably through the fibre or paper board sheets between the wood cleats.

The wood cleats provide the required resistance to the hammer shocks due to nailing the top closures in'place and in addition, reinforce the box against stacking and loading strains. With the fibre or paper end parts embraced between them, said wood cleats furnish composite nailing seats for the top closures, since the nails, while intended to be driven into the fibre, will manifestly take as well into the wood or more usually into the Wood on one side and into the fibre on the other.

The novel box is of particular advantage for use in shipping light vegetables, such as head lettuce, cabbage and the like, all of which require inspection and the necessary oppning of the box in transit.

The oxes are shipped flat to the packers or users, as in the case of other collapsible boxes, the wood cleats either being sent with the fibre or paper blanks or being supplied 'by the the users, as may be. commercially convenient.

lVhile in dcscribin my invention I have referred to several etails of construction and arrangement of parts, it is to be understood that the invention is not thereby limited except as may be pointed out in the appended claim.

I claimas my invention A box made of a single blank of fibre or paper board, the blank being cut and creased to provide a bottom wall, two side walls and two top closure flaps adapted to overlap along a median line of the box, the bottom wall having end extensions to provide ends of the full depth and width of the box, and the side walls having end extensions which are folded against the end walls to substantially cover said end walls, and wood cleats, a pair foneach end of the box, embracing the extensions forming the end of the box between them and being'stapled thereto, said' wood cleats extending the full width of the box and the top closure flaps of the box being folded down upon said wood cleats and nailed to the composite seats thus pro' vided.

In testimony that I claim the foregoing as my invention, I aiix my signature this 6th day of April, A. D. 1922.
