3 Claims.

This invention relates to knockdown crated shipping cartons. It has i or. its principal objects to devise a simple and inexpensive lightweight shipping carton of the above type which will knock down to form a compact package, which may be quickly and easily assembled and which is strong and rigid and well protected at its corners. The invention consists in the knockdown crated carton and in the parts and combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings,-which form part of this specification and wherein like symbols refer to like parts wherever they occur,

Fig. l is a top plan view of a knockdown crated shipping carton embodying our invention,

Figs. 2 and 3 are elevations oftwo adjacent sides of said carton,

Figs. 4 and 5 are vertical sections on the lines 4-4 and 5-5, respectively, in Fig. 1,

Fig. 6 is an enlarged horizontal cross-section on the line S-B in Fig. 2, I

Figs. 7 and 8 are perspective views looking at opposite sides of one of the end closure sections of the carton,

Fig. 9 is a perspective view of one of the two folding body sections of the carton,

Fig. 10 is an edge view, showing the folded body sections and the two end closure sections stacked one upon the other,

Fig. 11 is a fragmentary perspective view showing a modifiedcorner cleat construction for the corner formed by the scored intermediate portion of the body section,

Fig. 12 is a horizontal cross-section on the line l2-|2 in Fig. 11; and

Fig. 13 is an edge view of the modified body section in the flat.

Our knockdown crated carton comprises duplicate sections A, each forming two adjacent side walls of the rectangular body of the carton, each of the body sections A comprises a single rectangular strip l of corrugated board, fiberboard or like material divided by a score line 2 into a side wall panel 3 and a side wall panel 4, whereby said side wall panels are adapted to fold one upon the other in the manner shown in Fig. 10.

Secured flatwise to the outer face of the side wall panel 3 along the free end thereof is a wooden cleat 5 whose ends are flush with the longitudinal edges of said panel and whose outer side edge is disposed outwardly beyond said end of said strip a distance corresponding substantially to the thickness thereof and is provided with extensions in the form of outstanding dowels 6.

Secured flatwise to the outer face of the side wall panel 3 with its outside edge flush with the score or hinge line 2 is a wooden cleat I whose ends terminate flush with the longitudinal edges of the corrugated board strip l.

Secured flatwise to the outer side face of the side wall panel 4 along the free end thereof is a wooden cleat 8 that extends equal distances beyond the longitudinal edges of said panel and has its outer edge disposed outwardly of said end of said panel a distance corresponding to the thickness of the cleat 5. As shown in the drawings, the cleat 8 has dowel holes or recesses 9 in the inner side face thereof between the outer side edge thereof and the adjacent free end of the strip I. Secured flatwise to the outside face of the side wall panel 4 with its outside edge disposed outwardly beyond the score line 2 a distance corresponding to the thickness of the cleat l on the side wall panel 3 is a wooden cleat ID that extends beyond the longitudinal edges of the strip l the same distance as the cleat 8 at the free end of the side wall panel 4.

The upper and lower or longitudinal edges of the side wall panels 3 and 4 of each folding body section A are preferably strengthened, stiffened and protected by means of cleats II that extend from end cleat to end cleat of the respective side wall sections flush with said edges. The fastening means for the cleats of each body section preferably comprise staples or nails l2 that are driven through the corrugated board strip I from the inner side thereof into said cleats.

As shown in Fig. 10, each of the two body sections A of the carton may be folded along the score line 2 to bring the two side wall panels thereof into contact flatwise, thereby forming a compact package for shipment to the packer. In assembling the body of the carton, the two side wall panels of each folded body section A are swung away from each other along the score line 2 as a hinge and brought into position at right angles to each other to form two adjacent side walls of the cartons. In this opened or unfolded position of each body section A. the cleat 1 abuts edgewise against the cleat ID with its outer side face flush with the outer side edge of the latter, thus completely enclosing the corner formedby the two side wall panels 3 and 4 of said body section. The two unfolded sections A are then assembled to form the hollow rectangular body of the carton by bringing the end cleat 5 of each body section in edgewise abutting relation to the inner face of the end cleat 8 of the other section and entering the dowels 6 of the cleat. 5 into the holes 9 in the cleat 8, thus bringing the outer side face of the cleat 5 flush with the outer edge of the cleat l. with the two body sections thus assembled, the cleats 5 and 8 of the two body sections cooperate to form two diagonally opposite corners of the crating for the body of the carton and the cleats I and I0 form the two remaining corners of said crating. The cooperating corner cleats i and I are secured together preferably by glue and/or nails l3 driven through the overlapping margin of one cleat into the abutting edge of the other cleat. If desired, the corner cleats I and II may be secured together in a similar manner.

The carton is provided with duplicate top and bottom closure members B each comprising a rectangular piece of corrugated board, fiberboard or like material, ll having wooden slats or cleats that are secured flatwise to the inner face or surface thereof flush with the edges thereof and cooperate to form a rigid edge frame I! that snugly fits within the hollow rectangular body portion of the carton. If desired, the side walls of the body of the carton may be secured to the edge frame I! of each end closure B'by nails I.

driven through the cleats II and the fiberboard strips A into said edge frame. Secured fiatwise to the outer face or surface of the corrugated board portion ll of each end closure B flush with two opposite edges thereof are wooden cleats or slats II that extend beyond the other two edges thereof. One.end of each of the cleats l1 seats against the end of thecorner cleat l and terminates flush with the outer side face thereof and abuts edgewise against the inner side faces of the projecting end of the adjacent corner cleat I. The opposite end of the cleat ll cooperates in a similar manner with the corner cleats I and II. Both of the end' closure cleats have their outer faces disposed flush with the pro ecting ends of the corner cleats l and ll. The end closures are secured in place preferably by means of wood screws I. which extend through the projecting ends of the cleats l1 and are threaded into the ends of the corner cleats I and I abutting thereagainst. The edge frame I! of each end closure is secured thereto preferablyby nafls is that are driven through said frame and end closure into the cleats l1 and thus also secure said cleats to said end closure.

Figs. 11 and 12 illustrate a modified arrangement of comer cleats at the corners defined by the hinged or scored intermediate portion of the corrugated board strip I of each of the two body sections A In this construction, the wooden corner cleat Ia that is located entirely on one side of the score line 2 is spaced therefrom and has its outer edge rabbeted, as at lb, along its inner corner; and the other wooden comer cleat Illa has the portion thereof that is disposed opposite said rabbeted edge, grooved, as at il lb, from end to end. By this arrangement, the rabbeted marg n of the cleat la and the grooved margin I the cleat Ilia are spaced'away from each other in the unfolded position of the body section and said margins and the corrugated board strip together form an undercut or T-shaped vertical groove between said cleats adapted to slidably receive a key or locking member in the form of a wooden strip of substantially T-shaped crosssection. with this modified corner construction, the folding body section of the carton may be laid out flat for its entire length, while the locking key 20 serves, in the set-up position of the body section, to close the gap between the corner cleats Ia and Illa and to hold the corner square. The locking strip 20 is of the same length as the cleat la and terminates flush with the upper and lower end thereof and is adapted to be held against endwise movement in the T-shaped groove by the projecting end portion of the closure cleat II that is secured to said comer cleat by the screw it.

The hereinbefore described carton 'has several of each body section permits the two side wall panels thereof to be folded or doubled one upon the other to form a compact package. In cases where inner packing is required to protect or hold the articlein the carton, such packingmay be easily inserted before the second body section is 1 placed in position. The end. closures are reinforced .and stiil'ened by the cleats thereon and serve to prevent the carton from being distorted or thrown out of square; and these cover cleats, together with the cleats along the top and bottom edges of the sidewalls of the carton, serve to strengthen and stiflen said edges.

Obviously numerous changes may be made without departing from the invention. Therefore, we do not-wish to be limited to the precise construction shown.

What we claim is:

1. A knockdown crated carton comprising a rectan ular body, said body comprising two separate sections of corrugated board, fiberboard or the like, each of said sections being scored alon one line only to provide two adjacent side walls of said body and to permit said side walls to 101d one upon the other in knockdown form. separate cleats secured flatwise to the outside face of each of said corrugated board body sections at opposite ends thereof, the end cleats of one section lapping and being secured to the end cleats of the other section at two diagonally opposite corners of said body, and separate cleats secured to the outside face of each of said corrugated board bodysections adjacent to and on opposite sides of the score line thereon, th longitudinal edge of one of the last named cleats being flush with said score line and the longitudinal edge of the other of said last named cleats projecting beyond said score line whereby said last named cleats are automatically brought into overlapped relation at one. of the two remaining diagonally opposite corners of saidbodywhen said section is unfolded along the score line thereon to form two adjacent side walls of said body.
