2 Claims. 1

This invention relates to paperboard shipping boxes and more particularly to boxes of the ventilated type used for shipping live chicks, which are so constructed that the boxes may be stacked without cutting oif the supply of air to the chicks. The invention has for an object to provide a container of the type referred to which is so constructed that all parts may be shipped in the form of flat sheets which are so scored and cut that the parts can be quickly and easily folded and assembled, and the assembled and folded parts secured together without the use of tools or other special equipment.

A further object is to provide a box body blank formed to interlock with and secure intersecting partitions in place therein when folded to box form, and to provide interlockin parts on the box walls by which the walls may be secured together at the corners of the box after assembly on the partition members, without relative movement of the box walls.

A further object of the invention is to provide partitions that are held in place by interlocking engagement with the box body, that are provided with parts that interlock with the body of the cover to secure the cover in place and that have other parts that externally engage the cover flanges to hold them tightly against the box walls.

A further object of the invention is to provide crossing partition members that divide the box into compartments, reinforce the box body and cover, and serve as spacing members to provide ventilating passages over the tops and bottoms and around the side of the boxes when they are stacked.

With the above and other objects in view, the invention may be said to comprise the box as illustrated in the accompanying drawing hereinafter described and particularly set forth in appended claims, together with such variations and modifications thereof as are apparent to one skilled in the art to which the invention per tains.

Reference should be had to the accompanying drawing forming part of this specification, in which Fig, 1 is a perspective view of a box embodying the invention;

Fig. 2 is a fragmentary side elevation of one of the partition members;

Fig. 3 is a fragmentary section taken on the line indicated at 3-3 in Fig. 1.

which the box body is formed;

Fig. 8 is a perspective view showing a corner of the cover on an enlarged scale;

Fig. 9 is a horizontal section through the corner of the cover, and

Fig. 10 is a fragmentary plan view, showing a corner portion of the cover blank.

Referring .to the accompanying drawing, the box of the present invention has a body portion formed from a rectangular blank of sheet material, which is cut and scored to provide a rectangular bottom portion I and side walls 2 integral with the walls I and hingedly connected to the side edges of the bottom portion I, the blank being cut at the corners thereof and scored along the edges of the bottom I to provide side walls that are hinged to the bottom.

Theside walls 2 have vertical slots 3 midway between their ends that extend upwardly from the lower edges of the walls and terminate short of the top edges thereof. Within the box there are

partition members

4 and 5 which cross each other at right angles in the center of the box, the partition members being interlocked in the usual manner at the crossing point. At each end of each partition member, there is a projecting portionfi that is of a size to fit in the vertical slot 3 of the side walls 2, the partition members havin end edge portions 1 above the projections 6 that engage with the inner faces of the walls 2 above the upper ends of the slots 3.

In assembling the box, the two

partition members

4 and 5 are fitted together in crossing relation and placed upon the bottom I of the box with their end portions 6 registering with the inner end of the slots 3 of theside Walls. With the partition members in this position, the walls 2 of the box may be folded to vertical position to bring the upper portions thereof into contact with the edge portions 1 of the partition members, the portions 6 of the partition members projecting through the slots 3 to interlock the partition members with the side walls as shown in Fig. 1 of the drawing.

In order to quickly and easily secure the walls of the box at the corners without disturbing the interlocking connections between the walls and the partition members after the walls have been folded to vertical position, one of the walls 2 is provided at each corner of the box with a flap 8 that is hinged to the end thereof and adapted to be swung inwardly to a position at right angles thereto, and engaged with the inner face of the adjoining side wall when the walls 2 are folded to vertical positions. The contacting portions of the wall and flap adjacent each corner are provided with registering slots 9 and II) which are preferably formed in the upper edge portions of the wall and flap near the corner. The side wall has tongue II that is struck up from the slot 9 and which is hinged to the body of the wall along the lower edge of the slot 9. The slot II) of the flap has a tongue l2 that is struck up from the slot Ill and which is adapted to swing about a hinge 1ine disposed at right angles to the hinge line of the tongue II, the tongue I2 being connected to the flap along the side edge of the slot Hi.

In assembling the box on the partition members, the walls 2 are swung to vertical positions in engagement with the end portions 1 of the partitions, with the flaps 8 at the corners positioned in contact with the inner faces of the adjoining side wall. With the flaps so positioned the tongues II of the side walls can be pushed inwardly into the slots II] to the horizontal position shown in Fig. 6. This movement of the tongue I I pushes the tongue I2 inwardly to permit entry of the tongue II into the slot I0, and after the tongue I I has been moved to horizontal position in engagement with the bottom edge of the slot II], the tongue I2 can be swung back into the slot It] in looking position over the tongue II. The side walls of the box are thus quickly and easily locked at the corners of the box without moving of the side walls after the box has been assembled upon the partition members. The side walls may be readily disconnected by swinging the tongues l2 inwardly and returning the tongues II to vertical position, after which the walls 2 may be swung into the plane of the bottom and freed from the partitions 4 and so that the box may be knocked down for shipment or storage after it has been used.

The

partition members

4 and 5 serve to secure a suitable cover to the box and to reinforce the cover. As herein shown, the cover is also formed from a flat rectangular blank that has a rectangular body portion l3 to which marginal flanges I 4 are hinged, suitable score lines being provided along the edges of the body portion I3 to permit hinging of the flanges. In each corner of the cover, one of the flanges M has a flap I5 hinged thereto, which is adapted to be swung to a position at right angles to the flange to which it is hinged, and to engage the adjacent end of the adjoining flange. Near each corner one of the flanges I4 is provided with a slot l6 that extends inwardly from the free edge of the flange slightly more than half way across the flange, providing a locking tuck I! between the slot and the end of the flange. The flange which adjoins the flange with the slot at its end is provided with a hinged flap I5 and this flap has a slot I8 that is parallel with the flap hinge and that extends outwardly from the side edge of the flap which is alined with the edge of the body portion I3 to which the flange carrying the flap is hinged. The slot I8 has a flared portion I9 and forms a tapering locking tuck 20 that is adapted to be inserted through the slot I5 of the adjoining flange while the flanges are being folded to a position at right angles to the body portion I. In folding the flanges, the flap [5 is placed outside the end of the adjoining flange, and as the flanges are moved to a vertical position the tuck 2B is inserted in the slot l6 and the tuck I1 is inserted through the slot I8, the flaring portion I9 of the slot I8 serving to guide the tucks into place as the flanges approach their vertical positions, the flap and the adjoining flange being interlocked by means of the tuck portions I! and 26, as shown in Figs. 7 and 8 of the drawing. The interlocking portions of the flanges I l and flaps I5 can be readily disengaged to permit the flanges I4 and flaps I5 to be swung back into the plane of the body portion I3 when desired, so that the box can be rapidly assembled at the point of use and can be readily knocked down for shipment or storage after it has been used.

The body I3 of the cover is provided with elongated slots 2| that are adapted to receive projections 22 on the upper edges of the

partition members

4 and 5, the projecting portions 22 being provided with locking tongues 23 that are adapted to be bent laterally into locking engagement with the top of the cover, as shown in Fig. 1.

The projecting portions 6 of the partition members E and 5 have slots 24 in the top edges thereof, which are closely adjacent to the outer faces of the side walls 2 and which are adapted to receive the lower edge portions of the flanges I4 of the cover when the cover is placed on the box, so that when the cover is fastened in place by means of the tongues 23, the edges of the cover flanges are held snugly against the faces of the side walls by the projecting portions of the partition members. The partition members thus serve to reinforce the top, bottom and side walls of the box, the top projections 22 thereof serving to support other boxes with their bottoms faced above the cover, and the projections 6 serving to space boxes which are placed alongside one another so that when the boxes are stacked, air passages are formed between the tops and bottoms of the boxes and around the sides thereof.

It is to be understood that variations and modifications of the specific device herein shown and described for purposes of illustration, may be made without departing from the spirit of the invention.

What I claim is:

1. A shipping box having a body portion comprising a rectangular bottom and side walls integral with the bottom and hinged to the side edges thereof, said walls having slots intermediate their ends extending upwardly from their bottom edges and terminating short of their top edges, crossing interlocking partition members having end portions fitting in said slots and projecting past the outer faces of the side walls and end edge portions engaging the interiors of the side walls above the slots, said projecting portions having slots in the top edges thereof adjacent the outer faces of the side walls, a cover having marginal depending flanges telescopically engaging the outer faces of the side walls and extending into the slots in the top edges of the projecting portions of said partitions.

2. A shipping box having a body portion comprising a rectangular bottom and side walls integral with the bottom and hinged to the side edges thereof, said walls having slots intermediate their ends extending upwardly from their bottom edges and terminating short of their top edges, crossing interlocking partition members having their lower edges resting upon said bottom and top edge portions in the plane of the top edges of the side walls, said partition members having end portions fitting in said slots and projecting past the outer faces of the side walls and end edge portions engaging the interiors of the side walls above the slots, said projecting portions having slots in the top edges thereof adjacent the outer faces of the side walls, a cover 6 adapted to rest upon said top edge portions of the partitions having marginal depending flanges telescopically engaging the outer faces of the side walls and extending into the slots in the top 5 edges of the rojecting portions of said partitions.
