BOX.

Application filed March 17, 1922. Serial at. 544,537.

To aYl whom it may concern:

Be it known'that I, HARRISON B. WALTER, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Boxes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw- W ings, and to the letters of reference marked thereon, which form a part of this specifi cation.

This invention relates to improvements in boxes made of fibre or paper board and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

It has been proposed heretofore to use collapsible boxes made of fibre or paper board for the shipment of perishable goods,citrus fruit for example,which require inspection at one or more points in transit for purposes of examination and selection. This necessitates the opening of the box and then closing it again and securing the closure in place as in the beginning. Such boxes, how"- ever, have their closures secured in place by means of staples or by means of adhesive sealing strips, and they are therefore difiicult to open and after opening are more difficult to again close and secure the closure. In addition, in the case of fruit or the like, the adhesives. generally used have an objeo tionable efl'ect upon the contents of the packa e.

The object of the invention is to produce a collapsible fibre or paper board box, which is capable of top loading as distinguished from end loading, and which is so constructed that the top or lid may be secured in place by means of ordinary nails, so that the box may be easily opened by the use of the familiar nail puller, and as easily closed and secured in place again by nailing.

Another object of the invention is to produce a box of the kind which has ample strength to withstand strains both from within and from without, so that it may be included in stacks or vertical rows, with boxes placed one upon the other, without danger of being crushed or deformed by the weight of the boxes above it.

These and other objects and advantages of the improved box will be pointed out more fully as I proceed with my specification.

In the drawings 2-- Figure 1 is a perspective view of the im proved box;

Figure 2 is a perspective view illustrating the manner of stacking boxes of the kind;

Figure 3 is a view representing a longitudinal section through the box in a plane indicated by the ,line 33 of Fig. 1;

Figure 4 is a view representing a transverse section through the box in a plane in dicated by the line 4-4 of Fig. 1;

Flgure 5 is a view representing on an enlarged scale a partial transverse section.

through the box, in a the line 5-5 of Fig. 3;

Figure 6 is a plan view on a small scale of one of the end closures of the box;

Figure 7 is a plan view on a like scale of the mat or blank from which the body of the box is formed;

Figure 8 is a perspective view on a large scale'of one of the wooden cleats used in the box structure.

Referring now to that embodiment of the invention illustrated in the drawings: 10 indicates the body of the box. This is a rectangular tube, in this case shown as being equilateral, with sides 11, 11, a bottom 12, and two flaps 13, 14, which form the top or cover of the box. Said tube is formed from the mat or blank shown in Fig. 7 which is an elongated strip having a width equal plane indicated by to the length of the box, and which has transverse creases 16 spaced to define the bottom 12 and sides 11, 11 of the box and the two flaps 13, 14. The mat or blank 15 may be folded upon said creases when setting up the box for'use and may also be collapsed upon itself along said creases to produce a flat package for shipment to the packer or user.

17 17 indicate the end closures of the box. These, as illustrated herein, (see Fig. 6) are each made from a single blank or piece of fibre or paper board and consist of a main part 17 having an area equal to the cross-sectional area of the box body 10 and of flange extensions-17 17 at the sides of the blank and 17 at its bottom. The said flange extensions are defined by creases 17", by reason of which they may be folded at right angles to the main part 17 of the blank, when it is inserted in the open end of the tubular body and there secured in place by means of staples or otherwise, as shown in Fig. 1. r The side flange extensions 17 terminate short of the top edge of the main part 17, for a purpose that will presently appear. I

18, 18 indicate cleats made of soft wood extending between the sides of the box at its ends and at the top in position to receive and support the flaps 13 and 14 when they are folded down to close the box. Each cleat 18 is of a horizontal width equal to the width of the flange extensions on the end closure 17. They are preferably of somewhat greater vertical depth as shown in Figure 3. The side flange extensions 17* on the end closure 17 are cut away a distance below the top edge of said closure a distance equal to the depth of the associated cleat. Thus .When the cleat is placed in the end of the box, with its rear face against the top marginal part of the end closure 17 and its ends resting upon the top ends of the side flange extensions 17", the top edge of the cleat is flush with the top edge of said end closure, as shown in Fig. 5

The cleats are each secured in place by means of a long nail 19, taking through each side wall 11, into theend of the cleat (see Fig. 5) and by means of staples or other convenient devices of the kind, taking through the top marginal part of the as sociated closure 17 into the rear face of the cleat. (See Fig. 4.)

After the box is set up with the end closures and the cleats attached in place as described. it is packed through the open top. The top flaps are then folded down. the one upon the other upon the cleats to close'the box and are then nailed in closed position against the cleats as in the case of an ordinary wooden box. The nails used in this closing operation are readily removable b means of the familiar nail puller, when the contents of the box are to be inspected, whereupon the flaps may be raised and then be nailed shut again when the inspection is finished.

The side flange extensions 17 of the end closure provide supports for the ends of the cleats so as to aid them in resisting the shock of the hammer used in nailing the top flaps to the cleats and prevent the cleats from being torn from their connection to the marginal top part of said'closure. The cleats provide an efficient strut between the sides of the box and make it possible to stack boxes of the kind when placed on their sides, as shown in Fig. 2, without danger of collapsing under the weight of the boxes above in the stack.

One end closure 17 is shown rovided with ventilating openings 20. Tl iese may be formed in either or both end closures as deboxes when packed.

While in describin my invention I have referred to several etails of construction and arran ement of parts and shown the same in't e drawings accompanying my specification, it is to be understood that the invention is in no way limited thereto, except as may be pointed out in the appended claims.

I claim as my invention 1. A collapsible box of the kind described comprising a tubular body made from '1 blank creased transversely to define a bottom, sides and a top closure; end closures for said body, each being a blank cut and creased to provide a bottom flange extension and two side flange extensions, the latter terminating short of the top edge of said blank; and transverse end cleats of wood, each adapted to extend between the sides of the box, along and flush with the top edge of an end closure, with the ends of the cleats bearing upon the top ends of the side flanges of said end closures.

2-. A box made of fibre or pa r board, comprising a. tubular body ma e from a blank creased transversely to define a bottom, sides and a top closure; end closures, each being a blank cut and creased to rovide flange extensions at its sides and tt-om, said end closures being attached within the ends of the body to provide recesses in said ends; and transverse end cleats of y wood extending between the sides of said body in said end recesses flush with the top edges of said end closures, the sides being nailed to the ends of said cleats, and the end closures being attached to the rear faces of said cleats.

3.
