1Claim.

and inproviding a reinforcing member for the portion of the end wall having the hand hole whereby relatively light material may be used for the construction of the box.

An object of the invention resides in constructing the box from double faced corrugated board and in utilizing a wire reinforcing member inserted between the faces of the board and disposed in proximity to the hand hole.

A feature of the invention resides in inserting the wire reinforcing member in one of the flutes of the corrugated board at the locality of the hand hole.

Another object of the invention resides in constructing the box with hand holes at the opposite end walls of the box and in providing a separate reinforcing member for each end wall of the box situated in proximity to the hand holes.

A feature of the invention resides in providing a wire reinforcing member extending continuously about all of the walls of the box and across the end walls of the box in proximity to the hand holes therein. I

Another object of the invention resides in disposing the wire reinforcing member in the end wall of the box at a location immediately above the hand hole therein.

A still further object of the invention resides in' providing an insert having a portion adapted to lie adjacent the hand hole in the end wall of the box and in disposing in said insert the wire reinforcing member. I

A still further object of the invention resides in arranging the flutes of the corrugations so that the same extend vertically and in running the wire reinforcing member through all of the flutes and along the portion of the wall adjacent the hand hole therein.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

When corrugated paper board is used in the construction of boxes provided with hand holes in the end walls thereof, the corrugated board readily breaks and tears when the box ispicked up by inserting the hand in one of the hand holes. The present invention provides a construction by means of which the portion of the wall of the box having the hand hole therein at the locality of the hand hole is sufficiently reinforced by an inexpensive construction so that the box may be handled without danger of tearing or breaking the wall structure thereof.

The box shown in Fig. 1 is constructed from a blank illustrated in Fig. 2 and indicated in its entirety by the reference numeral l5. This blank is provided with two longitudinal scores It and I1 and with transverse scores l8, l9, 2| and 22. The scores l8, I9, 2| and 22 extend between the scores [6 and H. In addition to these scores the blank is sheared along lines 23 and 24 which are disposed in alignment with the scores l8, l9 and 2| and which extend outwardly beyond the scores It and I! to the edges of the box. The comers of the blank, as designated at 25, are cut away. By means of the various scores the box is divided into side walls 26,. and 21, end walls 28 and 29 and an end wall flap 3|. In addition, the upper side wall flaps 32, are provided with upper end wall flaps 33. Similarly lower side wall flaps 34 and lower end wall flaps 35 are formed which extend outwardly beyond the walls from which the same issue.

In the formation of the blank the flap 3| is secured to the side wall 26 by staples or wire stitches 36, as best shown in Fig. 1. In the erection of the box the flaps 34 and 35 are first turned inwardly and glued or otherwise secured together to form a bottom for the box. After the contents have been placed within the box the,upper flaps I 32 and 33 are similarly folded inwardly and secured to one another by glueing to form a closure for the box.

In the two end walls 28 and 29 are formed arcuate cuts 31 which are connected together by means of scores 38. These cuts-and scores define tabs 39 which may be folded inwardly into the interior of the box. When the said tabs are so folded as shown in Figs. 1 and 3, hand holes 4| are formed in the end walls of the box which are disposed below the upper edges thereof. The portions of the end walls of the box above the hand -holes 4| are designated by the reference numeral 42. In these portions of the end walls 28 and 29 are formed notches or openings 43 which communicate with the flutes 44 of the corrugations of the board. One of these flutes, designated by the reference numeral 45, is disposed immediately above the scores 88 and the notches 43 communicate with this flute. In this flute are inserted two rods or wirereinforcing members 46 which are of a length substantially equal to or slightly less than the width of the end walls 28 and 29. These wire members are confined to the portions 42' of said end walls and lie immediately above the hand holes 4| being disposed between the faces H and I2 of the corrugated board. When the box has been sealed and the tabs 39 pressed inwardly into the samethe parts occupy the position shown in Figs. 1 and 3. It will be noted that the wire reinforcing members 46 lie in close proximity to the upper edges of the hand holes 4| and extend throughout the width of the end walls. By means of this construction the box, at the locality of thehand holes, is greatly reinforced.

. thereof extend lengthwise.

causes the reinforcing member to bend at the proper locality and provides a reinforcement extending about all of the walls of the box. With this form of the invention a tie is provided between one end wall of the box and the other so that when one end of the box is grasped the stresses are distributed to the other walls of the box and the possibilities of tearing the blank, from which the box is constructed, is thereby greatly reduced.

In Figs. 7 to 11 inclusive a modification of the invention is illustrated which utilizes an insert placed adjacent each end wall of the box and which carries the reinforcing member of the invention. The box shown in Fig. 7 being similar to that shown in Fig. 1, the description thereof will not be repeated and the same reference numerals preceded by the digit 2 will be used to designate corresponding parts.

In the box shown in Fig. '7 the tab indicated at 39 in Fig. 1, has been completely out out of the box so that the hand hole 24| is clear. Along the inner surfaces of the walls 228 and 229 of the box is provided an insert 48 which is shown in detail in Fig. 8. This insert consists of a sheet of corrugated board in which the corrugations This insert has a hand hole 49 formed therein which is adapted to register with thehand hole 2 when the insert is placed within the box. The corrugations of the insert 48 extend crosswise of the same and may be parallel with or at right angles to the corrugations of the bank from which the box shown in Fig. 7 is constructed. In Fig. 9 the corrugations of the box are shown as extending parallel with the corrugations of the blank. In the particular flute 5| of the insert 48 which lies immediately above the hand hole 49 in said insert, is disposed a wire reinforcing member 52, similar to the reinforcing member 46. The reinforcing members 52 serve the same purpose and operate to reinforce the box and prevent tearing out of When a box constructed in accordance with my invention is to be carried about, the tabs 39 are forced inwardlylnto the box as shown in Fig. 3.

considerably stifiened and the entire box may be carried about'without danger of tearing out the portion of the end wall above the hand hole 4|.

In Figs. 4. 5 and 6 another form of the invention has been shown. In this form of the invention the manner of constructing the box is substantially the same as that shown in Figs. 1, 2 and 3 and the same reference numerals preceded by.the digit I will be used to designate corre- .sponding parts. In this form of the invention the notches-43 are dispensed with and a single reinforcing member 41 employed which extends throughout the entire, length of the flute I45.

, When the box is erected the wire member 41. is.

folded at the corners of the box defined by the scores I8, I 9, 2| and 22. This may be facilitated by weakening the said reinforcing member at the locality ,of'the scores l8, l9, 2| and 22. This the portions 242 of the end walls 228 and 229. With this form of the invention the box proper can be constructed in the conventional manner and the special feature of the invention incorporated in a seperateinsert, insertable into the box at the time of filling the'same.

Another form of insert which may be used with the box. shown in-Fig. "I, is illustrated at 50in Figs. 10 and 11. This insert is constructed from a blank 53 of corrugated board scored at 54, 55, 56' and 51. By means of the various scores a body portion 58 is provided of dimensions corresponding to the dimensions of the end walls 228 and 229. When-the said blank is folded along the said scoresa flange 59 is formed at the lowermost portion ofthe body 58 which engages the end wall'of thebox and holds the blank spaced therefrom. Asimilar flange 6| is formed at the upper portion ofthebody 58 which lies along the flap233 of'the box. In addition. a

flap 62 is provided which extends downwardly from the flange 6| and'an upwardly extendingflap 63 is formed which'lies between theflan'ge 62 and the body 58. The precisearrangement of these'parts is shown' in detail in Fig. 11. It will be noted that, due to the score 51, a rounded corner 64 is formed betweenthe. flaps 62 and 63 I resisting tearing when the end wall isgrasped through the hand hole therein. It frequently becomes desirable to produce a box having great er weight sustaining characteristics by running the flutes vertically. Such a box has heretofore been entirely too weak to permit of the use of hand holes. By the use of my invention the wire reinforcing member may be applied to such a box to stiffen and reinforce the same.

. In Figs. 12 to 14 I have shown a box in which the flutes run vertically instead of horizontally. Otherwise the construction shown in Figs. 12 to 14 is identical with that shown in Figs. 1 and 2. For thisreason the description thereof will not be repeated and the same reference numerals preceded by the digit 3 will be used to designate rr s di P It will be noted in Fig. 13 that the various flutes 61 of the corrugated board from which the box is constructed run vertically. At a locality shortly above the score "I in each of the end walls 328 and 329 is provided a wire reinforcingmember 68 which pierces the walls of the various flutes and extends completely across the end walls of the box. This wire reinforcing member is inserted into the blank through suitable notches 3, similar to the notches I dis-v closed in the form of the invention shown in Figs. 1 and 2. By means of this construction the wire reinforcing member is easily inserted into the corrugated board. To facilitate such insertion the entering end of the wire reinforcing member may be sharpened and when such is the casethetwofacings oftheboardmaintainthe wire member within the board.

invention may be used in conJunction with an insert disposed within the box and applicable as a separate unit therein. Since my invention utilizes reinforcing members of wire, such reinforcing members do not materially add to the cost or weight of the box.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

In a box having a wall constructed from corrugated board, said board being arranged to cause the flutes to extend transversely of the wall, said wall having a horizontal cut and; vertical cuts connected therewith to form a tab adapted to be bent into the box along one of the flutes to form a bight between said tab and wall and to provide a hand hole in the box with a roimded edge at the upper portion of the hand hole' and along said bight and a rod extending through a flute of said wall of the box within the bight and following along the rounded edge of the wall.

of said bight, said rod serving to reinforce and prevent the portion of the wall above the hand hole from tearing away from the wall, said rod further serving to restrain shifting of the portion of the wall at the bight out of the plane JOHN H. BURR.
