13 Claims.

My invention relates to boxes and has for an object to provides. box having an extremely rigid closure for closing the open portion of the box.

Another object of the invention resides in providing a box having double thicknesses of material at the corners of the box between the body of the box and the closure therefore.

A still further object of the invention resides in constructing the box with a body open at the upper portion thereof and provided with inwardly extending flaps bent from the free edges of said body.

A feature of the invention resides in mitering the corners of the flaps and in further providing a closure with members adapted to hold the flaps at the corners thereof in a common plane to cause the mitering edges of the said flaps to abut one another. 4

An object of 'the invention resides in constructing the closure for the box with a cover adapted to underlie the flaps on the body of the box and with a top adapted to overlie the flaps on the body of the box.

Another object of the invention resides in securing said cover and top together at localities disposed inwardly of the flaps on the body of the box.

A still further object of the invention resides in scoring said top along lines parallel to some of the edges thereof to provide tabs of a width corresponding to that of said flaps.

A feature of the invention resides in leaving said cover and tab intact along one of the edges thereof to permit of the insertion of one of the flaps of the body therebetween.

An object of the invention resides in constructing said closure with the tabs thereof foldable along said score mark to permit of the insertion of the flaps of the body between the cover and .40 tabs.

Another object of the invention resides in constructing said cover with flaps adapted to lie along the inner surface of the walls of the body of the box.

46 A still further object of the invention resides in constructing two of said flaps in two sections and in utilizing the cover and top of the closure for holding said sections in common planes to cause the meeting edges thereof to abut one another.

50 A feature of the invention resides in constructing the cover of a length equal to the distance between the end walls of the box and of a width equal to the distance between the facing edges of the flaps on the side walls of the box, and in scoring the top along a single line parallel to the end of the box to provide a single tab for the reception of the corresponding end flap of the body of the box.

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.

Fig. 10 is a developed view of the blank from which the body of the box shown in Fig. 6 is constructed.

In the shipment of fairly heavy commodities in paper boxes, considerable stress at the corners of the box occurs which frequently results in breakage of the box at such localities. Furthermore considerable weight is frequently placed upon the closure for such boxes. The present invention provides a box which may be constructed with reinforced corners and with a top of double thickness whereby suflicient rigidity and strength is procured and whereby these disadvantages are greatly overcome.

The box shown in Fig. 1 comprises a body 10 having

side walls

11 and 12 and

end walls

14 and 15, said body being open at the top and bottom thereof.. The body 10 may be constructed of -a single blank indicated at 16 in Fig. 5 which is scored along two parallel lines 1'7 and 18 and along a number of

transverse lines

19, 20, 21 and 22 to divide the box into various sections forming the

end walls

14 and 15 and the

side walls

12 and 11, previously referred to and a flap 26 at the end of wall 14. The marginal portions of the blank 16 are formed with V-shaped cuts 23 along the edges thereof at the

score marks

20, 21 and 22 and with

beveled cuts

24 and 25 at the ends of said marginal portions, which divide the same into a number of

flaps

27, 28, 29 and 30.

In the construction of the body 10 of the box, the blank is folded along the

various score marks

19, 20, 21 and 22 and the walls of the box secured together through the flap 26 which may be stapled, glued or otherwise attached to the adjoining wall 11. After the walls have been fastened together the

flaps

27, 28, 29 and 30 in both the upper and lower ends of the box may be folded inwardly as shown in Fig. 2 to lie in the planes of the top and bottom of the box. Due to the shape of the

cuts

24 and 25, said flaps become mitered along the comers thereof when so folded.

The body 10 of the box is provided with an upper closure 31 and a lower closure 32 adapted to close the open portions of the box. These closures being identical in construction, only the closure 31 will be described in detail.

The closure 31, as best shown in Fig. 3, comprises a cover 33 and a top 34 secured thereto. The cover 33 is of a size such that the same may snugly fit within the

walls

11, 12, 14 and 15 of the body of the box and is constructed with

flanges

35 and 36 along the edges thereof, adapted to be bent at right angles to the cover 33. These flanges lie within the body of the box, when the closure is properly applied thereto, and beneath the

various flaps

27, 28, 29 and 30 of the box proper. The top 34 of closure 31 is scored along two

parallel lines

37 and 38 which are parallel to the edges of said top and which are spaced a distance therefrom equal to or slightly greater than the width of the

flaps

28 and 30. A similar score mark 39 parallel to another edge of the box and spaced a distance therefrom corresponding to the width of the flap 27 extends completely across the top 34 and intersects the

score marks

37 and 38. By means of these score marks, the top 34 is formed with three

tabs

40, 41, and 42 which are individually foldable out of the plane of said box for a purpose to be presently more fully described. The top 34 is stapled as designated at 43 or glued or otherwise secured to the cover 33 inwardly of the

score marks

37, 38 and 39 and at the unscored edge of the box, a distance inwardly therefrom equal to or greater than the width of the flap 29, to leave the

tabs

40, 41, and 42 and a similar unscored portion 44 at oneend of the closure free from the cover 33.

In the application of the top 31 to the body 10 of the box, the following procedure is adopted.

All of the

flaps

27, 28, 29 and 30 of the body 10 are raised from the position shown in Fig. 2 and the flap 29 inserted into the space between the unscored portion 44 of the top 34 and the cover 33 which I have indicated at 45 in Fig. 4. The

various flanges

35 and 36 of the cover 33 are then folded inwardly as shown in Fig. 3 and the entire closure swung on the flap 29 through the score mark 17 thereof, to bring the

flanges

35 and 36 within the

flaps

28, 27 and 30 and within the interior of the box. When the closure approaches closing position, flap 41 is bent outwardly along score mark 39 as shown in Figs. 3 and 4. As the closure is brought in place and the flange 35 thereof passes the flange 27 the latter named flange is folded over the cover 33 to cause the same to lie in the plane of the top 34. The tab 41 is then folded down flat upon the flap 27 to hold said flap in place. Both of the

tabs

40 and 42 are next swung outwardly along the

score marks

38 and 37 as hinges. Such swinging of the

tabs

40 and 42 holds the tab 41 in proper position and while

tabs

40 and 42 are so swung the

flaps

28 and 30 are inserted between said tabs and the cover 33 and said tabs brought back into the plane of the closure. After all of the

flaps

27, 28, 29 and 30 become lodged in between cover 33 and top 34, the box may be bound by cord or metal straps as is now customary practice which holds the various parts rigidly secured together.

The box constructed as disclosed and with the closure applied thereto in the manner prescribed, forms an extremely rigid construction. From an inspection of Fig. 4, it will be noted that the corners of the box at the upper and lower portions of the body all have double thickness of material and also that the closures of the box are of double thickness thereby greatly reinforcing and stiffening the box so that the same will stand greater abuse than would be possible where a single thickness of material was employed. The closure, after the strap or cords have been removed, may be readily detached and reapplied as frequently as desired until the contents of the box have been consumed. The flaps formed on the body of the box are completely concealed and the edges of the body protected through the closure of the box, so that considerable protection is afforded the body of the box from the weight of other substances which may come in contact with the bottom closure of the box when the box is in use. Inasmuch as the closures are both removable and interchangeable, other 010- sures may be substituted in place of those which may become damaged and the body of the box used over again.

The form of the invention shown in Figs. 6 to 10 differs from that shown in Figs. 1 to 6 principally in that a box with an integrally constructed bottom is shown as compared with the other form of box which is open at both the top and bottom. The body of this box is designated at 78 and is constructed from a blank indicated at 46 and illustrated in Fig. 10. This blank is scored along four

longitudinal lines

47, 48, 49 and 50 and along two

transverse lines

51 and 52 which intersect one another as shown. The score lines 47 and 50 are spaced from the edges of the box a distance equal to the width of the flaps to be formed thereon while the other score lines are spaced so as to give the desired height to the side walls and width to the bottom of the box. The blank 46 is constructed with four V-shaped

cuts

53, 54, 55 and 56, which extend inwardly from the side edges of the blank at the score marks 51 and 52 and which extend up to the score marks 47 and 50.

In additionto these cuts, the blank is further severed along

lines

57, 58, 59 and 60 which coincide with the score lines 48 and 49 and which extend from the and edges of the blank up to the score marks 51 and 52. By means of the various score marks and cuts, the box is divided to form a bottom 61, two

sides

62 and 63,

complemental end sections

64, 65, and 66 situated at one end of the box, and

corresponding end sections

67, 68 and 69 situated at the other end of the box. The various parts of the box may be folded along the various score lines above mentioned and the end sections folded into overlapping position and secured together to take the form shown in Fig. 7. By means of the score lines 47 and 50 and the

cuts

53, 54, 55 and 56, the upper portion of the body of the box is provided with

flaps

70 and 71, adapted to be folded inwardly from the

sides

62 and 63 of the box and to form

flaps

72 and 73 adapted to be folded inwardly from the ends of the box in the plane of the flaps and '71. The

flaps

72 and 73 are formed with sections designated at 74, 75, 76 and '7'? of which the sections '76 and 77 lie in continuation of one another and the sections 74 and '75 also lie in continuation of one another. When these various flaps are folded, as shown in Fig. 7, the corners thereof become mitered and all of said flaps and flap sections lie in a common plane.

In conjunction with the body '78 of the box, a, closure 79 is employed which is shown in detail in Fig. 8. This closure comprises a cover 80 and a top 81 overlying the same similar to the closure 31. The top 79 is the same as in the other form of the invention, while the cover 80 is of the same length as the box but is of a width equal to the distance between the two

flaps

70 and 71 when the same are folded inwardly as shown in Fig. '7. It is to be further noted that no flanges are formed on the cover 80. By the construction of the closure 79 as specified, only one score mark 82 is required on the top 81 which provides a single' tab 83 along one of the ends of the closure.

The application of the closure '79 to the box 78 is quite similar to that described in conjunction with the other form of the invention. In this case however, flaps '70 and '71 need not be turned upwardly and it only becomes necessary to raise and fold the flap 83 in order to attach the closure to the body of the box proper. When the closure has been properly applied to the box, the box is bound with cord or metal bands as described .with the other form of the invention.

In the form of the invention shown in Figs. 6 to 10 inclusive, an extremely simple and inexpensive box is provided which is exceptionally rigid considering the amount of material employed in the same. The closure for the box may be removed and applied as required and being constructed of double thickness is sufiiciently strong to permit of stacking of the boxes and piling of other articles upon the closure. The closure of this form of box is somewhat easier to apply than that of the other form of the invention though less support is had for the closure along two of as herein disclosed, may be made within the.

scope of what is claimed without departing from the spirit of my invention.
