Application filed December 26, 1914. Serial No. 879,099.

Missouri, have invented certain new and useful Improvements in Paper Boxes, of. which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming a. part of this specification. I

My invention relates to improvements in paper boxes, one of the objects being to produce a reinforced and very strong paper box structure.

Another object is to provide simple means for sealing a paper box so that its contents cannot be removed without leaving indication that the box has been opened by an unauthorized person. I

Prior to this invention paper boxes, perticularly shipping boxes made of corrugated paper board, have been made by cutting and folding a single sheet of paper to produce a box body and closure flaps, and the ends of the sheet of paper have been connected by a strip of tape located at a corner of the box and cemented to adjoining side walls. The

sealing tape referred to is usually fully exposed at a corner of the box and since it is merely cemented to the box walls the tape may be readily loosened by moistening it with a wet cloth or sponge, and in practice the tape is frequently removed for; the purpose of pilfering the contents" of the box. The removal of the sealing tape Willpermit two of the side walls of the box to be spread apart, thereby permitting the removal of small articles from the box, and when the tape is again cemented to the adjacent side walls,'the box is? completely sealed and restored to its original condition.

In accordance with my invention, the vertical sealing tape at the corner of the box is so secured that it cannot be removed without mutilating some part of the box structure, which would indicate that the box'has. been torn open.

Figure I is a perspective view of a box structure embodying the features of my invention, the closure flaps at the upper and lower ends of the 'box body being shown in their open positions. .Fig. II is an enlarged de tail view of one corner of the box, showing the adjacent side walls which are connected by the sealing tape, and also showing the means for securing an end of the sealing tape to the box structure. Fig. III is a perspectlve view of the upper portion of the box, showing onlyone of the closure flaps inits open position. Fig. IV is a perspect1ve view, on a reduced scale, showing the box as it, appears, when all of the'closure flaps are closed and sealed.

The shipping box, shown in the accompanylng drawings, is preferably formed of of a single sheet of corrugated paper board,-

scored at 1, 2 and 3, and folded to produce a rectangular body having side walls 4, 5, 6 and 7. The ends of this folded sheet of paper are connected by a strip of tape 8, preferably of fabric, located at a corner of the box and -cemented to the side walls 4 and 5. The sheet of paper is also slitted to produce closure flaps 9 and 10, and scored at 11 to produce closure hinges. The strip of tape 8 extends beyond the closure hinges l1 and it is slitted at each end to produce a pair of integrally connected tongues 8 and 8 one of which is cemented to a closure flap 9, and the other being cemented to a closure 10.

A designates combined-seals and reinforcing elements each of which is preferably a band of tape, preferably of. fabric, surrounding and cemented to'the four side walls, and also cemented to the closure flaps 9 and 10. This sealing tape covers the end portions of the tape 8 and it is slitted to produce wings .12 secured to theclosure flaps 9 and wings 13 secured to the closure flaps 10. It will be noted that the wings 12 and 18. formed by slitting the tape A are integrally connected together.

In closing the box the inner flaps 9 are folded intothe box body as shownin Fig.

III, and the outer flaps 10 are folded over and cemented to the inner flaps 9. hen the closure flaps are folded and'cemented in this manner the tape wings 1:2 carried by the inner flaps 9' are concealed by, andfirmly secured to, the outer flaps 10. The sealing tape isthus secured so that it cannot be removed by moistening its outer surface, and owing to the peculiar manner in which this sealingtape is folded the strip of tape 8 cannot be loosened from the box structure.

7 The tongues 8* at the ends of the tape 8 are ered' the outer flaps 10 which are cemented to the inner flaps 9 and wings 12 of the tape 8. In this connection it is important since the tape on the inner flaps is inaccessible the sealing tape cannot be removed Without mutilating the box structure. Also the I tape 8 covered by and secured to the sealing tape A cannot be removed Without mutilating' some .part of the structure thereby indicating that the box has been opened.

' In addition to serving as a seal or telltale device, the sealing'tape ties the box \valls together, reinforces the box structure, and protects the box at the corners Where boxes of this kind are usually damaged in shipment. As Will be obvious, the tape may be of such texture, thickness and. strength as to add greatly to the stability of the box Wherever the tape is present in my box.

I claim: 1. A box comprising a sheet of paper, slitted to' produce inner and outer closure flaps and scored to produce closure hinges,.,

astrip of tape cemented to said sheet of paper to connect the ends thereof, and sealing tape located at corners of the box so as to cover the end portions of said first named inner flaps so as to conceal the sealing tape i on said inner fiaps.

2. A i'einforced paper box comprising a single sheet of paper slitted, scored and folded to produce'a box body having four side walls and inner and outer closure flaps hinged to said side walls, a strip of tape cemented to said sheet of paper at the junction of tWO-OfSilld Walls so as to connect the ends of said sheet of paper, each end portion of said first named strip of tape being slitted to provide tWO integrally connected tongues one of which is cemented to an inner flap and the other being cemented to an outer flap, and combined seals and reinforcing elements each of which comprises a band of sealing tape surrounding and cemented to said four side Walls-and covering the end portions of said first named strip of tape, each band of sealing tape being cemented to the inner and outer closure flaps at one end of the box, and the outer flaps being folded over and cemented-to the inner flaps so as to secure and conceal the tape onthe inner flaps.
