7 Claims. (Cl. 229-31) The subject matter of this invention is a singlepiece carton of the general type known in the industry as a folder or wrapper, which signiiies that a single blank constitutes both body and lid, such carton preferably to be made out of corrugated board and particularly intended for the shipping of live chicks. Among the particular aims of this invention are the construction of such a carton with all parts in a single blank, including the top, the fastening means, and the external vertical spacing means, the construction being such that the blank can be assembled into a finished box without the use of any extraneous fastening means such as staples, adhesive, and the like. The purposes of this invention further include arrangements whereby the interior elements in the box can be inserted after the box is assembled; means whereby the chicks in the box will be protected from being caught in any of the box elements; means improving the interior ventilation of the box; means for giving the chicks a better foot-hold in the box and for absorbing moisture, droppings, and so on, thereby eliminating the need of straw, wood wool or the like for this purpose; the provision of integral construction elements which not only interlock the box elements, but also space successive piled boxes and transmit weight down a column of stacked boxes without additional or separate strengthening means and without encroaching upon the interior floor space of the box; the provision of locking means which also furnish side spacing; the arrangement of top and ends to permit fastening either with or without a strip of adhesive.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and'particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain structure embodying the invention, such disclosed means constituting, however, but one of various structural forms in which the principle of the invention may be used.

In the accompanying drawings:

Fig. 1 is a perspective showing the'box completed and closed;

Fig. 2 is a plan view taken slightly below the top, namely on the plane 2-2 of Fig. 6;'

Fig. 3 is a plan view of the developed blank;

Fig. 4 is a detail of a corner key piece before folding;

Fig. 5 is a transverse vertical section on the plane I! of Fig. 2, with part of the interior partition broken away; and

Fig. 6 is a longitudinal vertical section on the plane 6-6 of Fig. 2, but modified by omission of key pieces and fastening tabs. This figure also shows the spacing of successive boxes in stacks. In chick boxes of hitherto known construction it has been customary for the top and the body of the box to be separate pieces; for the bodies and lids to be assembled by stapling and for the internal partitions aiso to be stapled or otherwise rigidly secured in placeffor the vertical spacers to take up some of the interior floor space of the box; and for interior padding, if any, to be of loose material such as excelsior, wood wool, hay or the like, separate in each of the interior cells.

The practice of having the bodies and lids separate has given rise to difficulties in shipping the blanks due to the fact that the two sorts of blanks, being of different sizes, were most economically handled in separate bundles and it could easily happen by mistake that the number of tops and number of bottoms included was not the same, or that a bundle of one or the other might get lost from a large order. Similarly, using staples in the assembly of the boxes or for securing the interior partitions has slowed down the assembly process and made it more difllcult and expensive. Also it has been customary for the bottom of the box to be simply one face of the construction material, and since the construction material is usually double face corrugated board, this has meant either that the bottom surface, which constituted the flooring on which the chicks stood, was smooth and slick, thus making it impossible for the chicks to hold on when the box was moved rapidly and causing them to be thrown around and at times injured, or else that straw, excelsior or something of the sort had to be used, requiring one more preparatory step, and giving a filling likely to bunch up.

Another trouble frequently encountered in chick boxes has been due to the fact that the partitions normally bear down firmly upon-the box ings such as to catch the head of a chick or otherwise cause danger.

The foregoing and various other difficulties are avoided by my improved construction.

Referring now to the figures of the drawings, the box when closed constitutes a ventilated carton, one-piece except for the partitions and except for optional corner fasteners. The top is of two flaps l, I, each bendable with relation to its respective side 2 along the line 3. External vertical braces 5, each formed of the box material and directed inwardly on diagonal lines when seen in plan view, occur at the four corners. Key pieces 6 which also act as horizontal spacing members are preferably used to aid inholdins the sides together although not essential to all phases of the invention, Short end tongues I, 8, on the interior partitions 9, II), respectively, extend into vertical slots II and I2 in the box sides, these slots being slightly higher than the height of the respective tongues for a purpose to be later described. Appropriate ventilating slots 4 are formed in the sides and top. These slots are long and narrow instead of having the usual round holes. Consequently a smaller number of openings provides adequate ventilation, and in warm weather, when much ventilation is necessary, suflicient opening is made by removing the knockouts from comparatively few slots instead of from a large number of small holes. The slots are too narrow for chicks to put their heads through. In accordance with the usual practice in box making, the material of these vents is ordinarily not completely severed, so that a greater or less number can be knocked out to provide the degree of ventilation appropriate to the season of the year.

Each of the top flaps l, l is finished with end tongues It, IS, bendable at the base, each passing down through a slot 2| in the end wall 20 of the box. A pad 30 on the floor 3| of the box, preferably fastened thereto as by adhesive, has a roughened surface as indicated diagrammatically in Fig. 2. This pad, besides being roughened to give a foothold for the chicks, is best made of soft stock which enhances the foothold properties and also absorbs moisture.

The method of assembling .the box will be apparent by a comparison of Fig. 3 with the other figures. The blank, as shown, is of rectangular outline, comprising the bottom area 3| which is separated by fold lines 3, 3 and 40, 40 from the sides 2 and ends 20 respectively. Slots II and I2 through the ends 20 and sides 2, respectively, and transversely directed, are to take the end tongues I and 8 of the interior partitions and Ill. Slots 42 at each end of the panels 2 and 20, parallel to and spaced from the bottom fold lines 3 and 40, receive the folded key pieces 6 in the completed box, as will be understood by reference to the other figures. The top flaps I are bounded along their inner edges by the folding lines 3, and are diagonally slotted asat 50 for passage of the corner braces 5.

The corner braces 5 comprise in detail two triangular panels 5l and 52, joined by the fold line 53, and joined to the sides 2 and ends 20 by fold lines 55 and 54. Sllts 56 and bend lines 51 set oil locking tabs 58 which swing out from the upper part of the corner braces 5, as shown in Fig. 1, to keep the lid down, this feature being similar to Patent No. 1,994,318. In addition there is a finishing flange 23 foldable along the line 24 along the ultimate upper edge of each of the ends 20; the slots 2| are cut therein. At each of the four extreme corners of the blank a key piece 6, opened out, and perforated medially lengthwise by a slot BI, is severably attached to the tongue is and panel 52 as at 62 and 33. These key pieces 6 are transversely scored as at 64 for folding into the final shape which is best seen in Fig. 2.

To assemble the box the sides and ends'are raised into a vertical position and the corner braces 5 are folded inward, bending along the lines 53, 54 and 55, to make, in effect, a brace of double thickness. Such folding obviously brings the slots II and I2 into vertical position and brings each pair of slots 42 into mutual horizontal alignment'on opposite sides of 5. If corner fasteners are to be used, the blanks 6 are detached, folded upon themselves on the line 54, thus forming them into open-ended U-shaped key pieces as best shown in Fig. 2. The prongs of these key pieces are slipped through the slots 42, straddling the corner brace 5 thereby keeping it from spreading and keeping the ends and sides 2 together at their junction lines. It will be apparent. that glue, sodium silicate, or other adhesive may be used on the pieces 5 to augment the holding by friction. Also obviously the key pieces may be of other material, such as metal.

' The upper portions of the corner braces 5 stand above the level of the lid when closed, and are embraced within the slots 50. The slots 50 can thus either provide the entire fastening against the spreading of the vertical walls of the container, although preferably they will be reenforced by the key pieces 6. When the key pieces 6 are used their outward projections serve the additional useful purpose of spacing adjacent boxes sldewise for air circulation.

It will be observed, particularly from Figs. 5 and 6,-that the corner braces 5 constitute brackets which carry the load downward to the lower apex of each box corner without encroaching upon the floor space or forming a hazard for chicks, and the extension of these braces above the lid furnishes the necessary vertical spacing for ventilation. I

Above the pad 30 the interior partitions 9 and Ill rest, positioned by their end lugs I, I and l, I which project out a short distance through slots II, II and l2, l2 of the ends and sides of the box respectively, but these lugs, asshown in Figs. 5 and 6, do not extend for full partition height, and as shown in Fig. 1, are not as high as the slots. Furthermore the partition tops are .well below contact with the inside of the lid. Thus the partitions may be styled floating, because some vertical movement is allowed, with the result that if a chick gets its toes caught under a .partition, it can pull them out without injury. For the further prevention of toe catching, the partitions are notched along their bottom as at 32, leaving only intermediate bearing points 33. The notches 32 and .the stopping of the partitions below full height allow adequate cross ventilation without other interior openings. In accordance with the usual practice the partitions are interengaged at the middle by the ordinary type of upward and downward slots. It is possible, by slightly flexing the partitions 9 and In short of the cracking point, to insert the lugs in the slots of the assembled box (the lid of course being open) and allow the partitions to spring out to their full length, whereupon they will remain fastened in place, but with some freedom of movement.

To close the box for shipping, the top flaps l are turned down along the lines 3, 3 with the slots 50 embracing the upper projections of the corner braces 5, the locking tabs 58 are swung out over the lid, the end tongues I6 are tucked down through the slots 2|. Further fastening means, such as tape, string, or the like, may also be employed.

It is obvious that the principles of this invention may be employed for boxes other than those used for shipping chicks, and that the interior arrangements, such as pad and partitions, may be varied or omitted according to the character of the merchandise to be contained.

It will be seen that I have invented a carton to be formed from a one-piece blank, self-locking, and having novel bracing and spacing arrangements as well as having improvements in the interior when the purpose to which the carton is put makes the use of such improvements appropriate. Thus when used as a chick box it requires no padding other than that included in the manufacture of the box, and does not require spacing sticks.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention:
