Patented July 15, 1930 UNITED STATES HARRISON B. WALTER, OF CHICAGO, ILLINOIS, ASSIGNOR TO CONTAINER CORPORA- PATENT OFFICE TION OF AMERICA, OF CHICAGO, ILLINOIS, A. CORPORATION OF .DELAWARE BOX Application filed June 27,

The present invention relates to containers and more particularly to cartons or boxes constructed of paper, fibre or other light material. One object of the invention is the provision of a box or carton which can be made substantially from a one-piece blank in which the material is distributed and arranged in such a manner that the box is of a sturdy construction throughout and is especially strengthened at parts which are likely to be subjected to the greatest crushing forces. Another object is to provide a box or carton of the character described which provides a maximum of strength of parts with a minimum of material employed. Other objects are to provide a box which may be speedily and economically manufactured and assembled ready for use.

To these and other ends the invention resides in certain improvements and cornbina tions of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Fig. 1 is a perspective View showing the box assembled Fig. 2 is a view of the box blank, and Fig. 3 is a perspective detail view of a partition member for use with the box.

Similar reference numerals throughout the several views indicate the same parts.

The present embodiment of the invention provides a box construction of the class described which is strong and durable and at the same time light and easily handled, being particularly advantageous in the packing of light, fragile goodssuch as crackers and waters zamongotherithings. The box may be made from substantially a one-piece blank which-may be; handled inflat condition until such-time .as it is desired to assemble and use the-same.

Referring inore particularl to the draw- 'ings,-numeral-10'indicates the ox as a whole, which is' preferably. formed of solid fibre board',"-althou-gh .anytype of material such a's'cardboard' or icorrugated board, for example, may be employed'to equal advantage.

formed from a blank such as illustrated in Fig. 2. In the present instance, this blank is ends and sides being separated from the bottom by score lines 14, 14 along which the sides and ends may be bent upwardly in assemblingthe box. Extending from the sides of the end walls 12 are flaps 15, 15 of a width approximately equal to the width of the end walls, and of a length equal to substantially one-half of the length of side walls 13 for a purpose which will be presently brought out. The end walls 12 are each provided with an extension 16 which serves to close the opening between wall 12 and the cover of the box when the box has been set up. One of the side walls 13 is preferably provided with a relatively narrow flap extension 17, similar to the extensions 16, and the other side wall 13 is preferably formed with a relatively wide extension 18 which serves as the cover for the box. The blank is provided with suitable slits 19, 19 which separate the flaps 15, 15 from the side walls 13, 13.

The extensions 16 and 17, the cover 18, as well as the flaps 15 are all separated from their respective walls by means of score lines 20 along which the parts may be readily bent in a manner which is well understood.

In forming the box, the sides 13, 13 and the sides 12, 12 are bent inwardly at right angles to the bottom 11 and the flaps 15 are brought inwardly so as to lie inside of and against the long side walls 13 to which they may be secured in any (1 asired manner. In the present instance, the flaps 15 are secured to the side walls by means of staples 21.

' The flaps 15 may somewhat overlap or may be made to exactly abut each other at the vertical central part of the long sides 13, but in the preferred form of the invention these flaps are formed of such a length that, when the box is assembled, their adjacent free ends are slightly spaced from each other. While the flaps 15, 15 are preferably of such a length as to terminate substantially centrally of the side walls, the particular point at which the flaps te'rminateis more or le s immat rial so lon as the flaps cover substantially the area 0 the side walls.

For the purpose of strengthening the box to prevent its being crushed under objects placed thereon, and to form compartments within the box, there is preferably provided a partition member 22 disposed transversely the box and abutting with its respective ends against the sidewalls at a point between the adjacent ends of the flaps 15, which ends also serve as abutments to prevent lateral displacement of' the partition.

The partition 22 may, if desired, be provided with means whereby it may be interlocked with the side walls of the box. To this end an extension 23 is provided at each end of the partition, which is adapted to be bent over so as to lie between the side wall and the end portion of one of the flaps 15. To facilitate the insertion of the extension 23 between the wall 13 and the end of the flap 15, at least one of the flaps 15 on each side of the box is secured thereto so as to have a substantial portion of its end free from the side 13, as clearly indicated in Fig. 1.

The partition may be inserted in place by sliding it downwardly after engaging the extension 23 behind'the free end portions of the flaps 15. With this construction of the partition it may be easily secured in position without danger of it being displace-d. The free end of one of the flaps 15 engages over the extension 23 and abuts the partition 22 on one side and the end of the other flap 15 abuts the partition 0n the other side, see Fig. 1. The partition 22 may be formed of any desired material, but it is preferably formed from the same material of which the box 10 is constructed.

After the goods have been placed within the box, the flaps 16, 16 and 17 are folded inwardly over the contents and the cover 18 is then swung downwardly into position where it may be secured in any desired manner. as by means of ordinary gummed tape.

The present invention thus provides a box having relatively short ends and relatively long sides, the latter of which are reinforced by flaps secured thereto, which provide, in effect, with the wall 13, a side wall of double thickness which effectively resists all but the most severe crushing strains. With the part tion 22 in place and the box in sealed conditlon, the partition is securely interlocked with the side walls, and the cover will contact at its middle with the partition and will be supported by it so that the box is able to sustain relatively heavy blows or pressure without collapsing sufficiently to injure the material carried therein.

While the present description sets forth a preferred embodiment of the invention, numerous changes may be made in the construction without departing from the spirit of the invention, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

Having described my invention, I claim:

1. A box comprising a bottom, side walls and end walls integral therewith, reinforcing flaps integral with said end walls, and adapted to be secured against said side walls to reinforce the same, the ends of said flaps terminating adjacent the mid-portion of said side walls, means for securing said flaps to said side walls, one of said flaps on each side of said box having a free, unsecured portion adjacent its end, a partition disposed transversely said box, said partition having laterally projecting extenslons at each end, each extension being adapted to lie between one side of the box and the free end of the flap secured thereto.

2. A box comprising a bottom, side walls and end walls integral therewith, reinforcing flaps integral with said end walls and adapted to be secured against and reinforce said side walls, the adjacent ends of said flaps being somewhat separated from each other and terminating adjacent the middle of said side walls, means securing said flaps to the interior of said side walls along lines spaced from the ends of said flaps, a transversely disposed partition in said box, a laterally extended portion on at least one end of said partition adapted to lie between the side wall and an adjacent free end portion of one of the flaps.

3. A box comprising a bottom, side walls and end walls integral therewith, reinforcing flaps integral with said end walls, and adapted to be secured to said side walls to reinforce the same, the ends of said flaps terminating adjacent the mid-portion of said side walls. means securing said flaps to the interior of said side walls, and a partition disposed transversely said box, the ends of said flaps being spaced from each other the thickness of said partition, whereby said ends serve as abutments to retain said partitions from displacement.

4. A box comprising a bottom, four walls integral therewith, reinforcing flaps integral with each of an oppositely disposed pair of said walls, said flaps being adapted to be secured to the remainin walls to reinforce the same, the ends of sai flaps terminating adjacent the. mid-portion of said remaining 'walls, means securing said flaps to the interior of said remaining walls, a partition disposed across the said box, and means for interlocking the ends of said artition with the free ends of at least one 0 said reinforcing flaps at opposite sides of said box.
