SNYDER, F PHILADELPHIA, PENNSYLVANIA i A R'r or MAKING CARDBOARD BoxEs Application filed December 12, 1930. Serial No. 501,770.

This invention, generally stated, relates to the art of box making and has more especial relation to boxes made of cardboard, particularly those used in the cigar box industry.

One object of the present invention is to provide a box made of cardboard comprising a tray and a shell, the end walls of the tray being so arranged that the inner faces thereof abut against the end edges of the side walls of the box, whereby the side walls of the tray are flush with the vertical, outer edges of the tray ends.

A further object of the present invention is to provide in a structure of the character stated a cardboard assembly of relatively uniform thickness in which a ridge is provided to accept the lid or cover so that the lid or cover comes to a firm, uniform seating,

whereby mutilation of the box contents is prevented.

A further object of the present invention is to provide a box of cardboard the tray of wh-ich is longitudinally scored when died out so that the vertical, outer edges of the end walls are out of alignment with the said longitudinal scoring.

A still further object of the present invention is to provide a box of cardboard provided with a hinged lid or cover, the hinge being formed offabric, adhesively secured along one edge between an outer wall of the tray and the inner wall of the shell, and adhesively secured to the inner face of the lid along its opposite edge.

Other and further objects of the present invention consist in the provision of general details of construction and arrangement and combination of parts for attaining the results sought by the foregoing objects.

The invention consists of the novel construction hereinafter described and finally claimed. e

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. 1 is a plan view of the various parts going to make up the box embodying the invent-ion;

Fig. 2 is a top or plan view of a box embodying the invention, showing the lid or cover in open position; i

Fig. 3 is a view in cross-section taken upon the line 3-3 of Fig. 2;

Fig. 4 is a view in side elevation of a box embodying the invention with parts broken away and showing the lid in closed position;

F ig. 5 is a fragmentary view in perspective illustrating one corner of a box structure embodying the invention showing the parts about to be assembled.

For the purpose of illustrating our invention we have shown in the accompanying drawings one form thereof which is at present preferred by us, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities ofV which our invention consists can be variously arranged and organized and that our invention is not limited to the' precise arrangement and organization of the instrumentalities as herein shown and described.

Referring to the dra-wings in detail, and with especial relation to Fig. l, there is disclosed at the right hand side of the drawings a blank 10 of cardboard, died out in accordance with the invention. This blank when properly died out, scored, and folded constitutes the tray of the boxstructure. To the left of the blank 10 just referred to`is disclosed another bla-nk 11 which when prop' erly died out, scored, and folded forms thc shell for the tray as formed from blank 10. The reference numeral 12 designates a lid or cover and the reference numeral 13 designates a strip of fabric which may be muslin 0r other suitable material, forming what is usually termed hinge-cloth.

The blank 10 is provided with a bottom section 14, side flaps 15 and 16, and end flaps 17 and 18. In stamping out the blank 10 the same is scored laterally along the lines 19 and scored longitudinally along the lines 20. The longitudinal scoring 20is out of alignment with the outer, vertical edges 21 of the end flaps 17 and 18. In alignment with the lateral scoring 19 the blank 10 is cut out at 22 so that the flaps 17 and 18 are free of the side flaps 15 and 16.

Taking up now the blank 11, the same comprises a. bottom section 23, side flaps 24 and 25, and end'iiaps 26 and 27. The blank 11 is scored longitudinally as at 28 and scored Alaterally as at 29. In the connection it is to be noted that the longitudinal scoring 28 is in alignment with the outer, vertical edges 30 ofthe end flaps 26 and 27.

A description will now be given of the manner of assembling the parts shown in Fig. 1. The side iiaps 15 and 16 ofthe blank 10 forming the tray are folded along the scoring 20 and the end flaps 17 and 18 are folded along the scoring 19 so that the inner faces of the end flaps 17 and 18 abut atwise against the vertical edges 31 of the side flaps l5 and 16, as clearly shown in Fig. 5. In this position of parts it is to be noted that the outer faces of the side flaps 15 and 16 are flush with the vertical edges 21 of the end flaps 17 and 18, so that a continuous smooth surface is provided in contradistinction to a surface having a rough corner, as would be present if the opposed vertical edges 21 and 31 of the iaps 17 and 18 merely met as would be the case if the scorings 2O were in alignment with the vertical edges 21 o-f the end flaps 17 and 18. The tray thus formed from the blank 10 has tted therearound the shell as formed from blank 11, and the various flaps of the f tray and shell adhesively secured together. At the time the iiaps are adhesively secured together the lower edge of the hinge-cloth 13 is positioned between the outer wall of the tray flap 15 and the inner wall of the shell flap 24, and the opposite edge of the-hinge-cloth is adhesively secured to the inner face .of the lid or cover 12, as best seen in Figs. 2 and 3.

In assembling the box, the tops of the end flaps 26 and 27 of the'shell as formed from blank 11 extendin a plane above the top edges of the side flaps 24 and 25 and also extend in a plane above the top edges of the iiaps 15, 16, 17, and 18 of the tray formed from blank 10, as best seen in Fig. 3. This arrangement of parts provides flat top edges upon whichthe box lid may rest, and at the same time provides a rim or flange at the box ends. This flange or rim prevents endwise movementl of the lid or cover in closed position and at the same time affords a neat appearance in that the end, lateral edges of the box lid are not discernible.

A box of cardboard constructed as above described is very strong and durable and the blanks may be died out without the employment of specialtools. The blanks 10 and 11 when died out may be covered with paper by means of standard ,wrapping machinery. Further, the box structure may be inexpensively put together. Also, by having the hinge-cloth arranged between the walls of the tray and the shell and secured to the inner face of the box lid, a much strengthened arrangement of hinge-joint is provided and the hinged parts are concealed without the necessity of weakening of the rear Wall of the box. In the drawings no attempt has been made t0 show the paper covering since it would only tend to confuse the cardboard structure embodying the invention. However, it may be stated that after the tray blank has been died out and scored, it is covered with paper by means of conventional wrapping machinery of the Stokes and Smithltype. After the shell blank has been died out and scored it is covered with paper by means of standard wrapping machinery of the Stokes and Smith type. The lid or cover is also covered with paper by conventional machinery.

Itis to be noted that the stock from which the tray is made is appreciably thicker than the stock from .which the shell is made. Also, it is our intention to include as part of our invention the manner or method of fabricating a box of said board so that the end flaps of the tray abut flat-wise against the vertical ends of the .side flaps of the box.

Further, it is our intent to include the manner or method of box formation in which the hinge-cloth is 'introduced adhesively between the outer wall 0f the tray and adhesively applied directly to the cardboard stock of the inner face of the lid or cover in contradistinction to the rear wall of the box.

What we claim as new, and desire to secure by Letters Patent, is:

1. A cardboard box formed by nesting an inner blank and an outer blank, the inner blank having four flaps constituting sides and ends and being longitudinally scored out of alignment with the outer lateral edges of its end flaps whereby when said four flaps are folded into box form the end edges of two {ia-ps abut the inner side faces of the other two iiaps, the outer blank having four flaps folded up andadhesively secured to the four flaps of the first mentioned blank, and means securing the outer flaps together at their corners the both blanks having such thickness as to substantially aid in providing necessary rigidity in the side and end walls of the finished box.

2. A cardboard box of the character stated in claim l characterized by the top edges of the outer blank lying in a plane above the top edges of the inner blank, thus to provide a ledge to accomodate a lid, and a lid having hinged relation with said box for. seating upon said ledge.

3. A cardboard box of the character stated in claim 1, characterized by a hinge cloth connecting said box, the lower marginal edge of said hinge cloth being adhesively secured between adjacent Walls of said inner and outer blanks.
