applmstimaredfinys, 190s. serial No. 43mm To all whom 'it may cmicm: l

Be it known-that I, :CHARLES S. Bnm, a citizen of 'the'.United States, anda resident of East apolefin thecounty of Norfolk ,o \Massachus etts, have `invented certain new `and useful Improvements in Paper Boxes, of which the following is' a specification, reference being had to th'e ac- `companying drawings, in which` Figures l and 2 are plan views of pieces of strawboard, cardboard, or the like, -out of which my improved box is constructed; Fig. 3 is a plan view, slightly on the per.- spective, showing the two'parts illustrated in Figs. 1 and 2, united together and in a flat or knock down fposition; Fig. 4; is a perspective view of the' parts shown in Fig.

- 3 set up in rectangular form; Fig. 5 is a been my experience that the parts assembled respectively, A, B, A', .B, and that the comlperspective view of the box with the parts assembled' in final position and having the bindin strip aiiixed thereto.

Siml ar letters refer @to similar parts throughout the several` views. f

In the construction of folding paper boxes of substantially rectangular form, it has together must have a-certain strutting action, that 1s to say the parts must mutually combine with eachotherin order to aiord' strength and rigidity to the box in orden -to attain the requisite strength where the boxes are composed, as is my improved-box `herein descrlbed, of friable material. It is also necessary that the parts should be so 'combined as to be capable of being packed in a flator knock down conditlon so as to economize freight charges and, at the vsame time,` be capable of-being set up into final positionin a simple and eliicient manner when such boxes are to be used by the consumer. It is also of commercial advantage, where large numbers of boxes are used, lto economize, as fary as possible, inthe use of material, to the end that the various parts which go to make up the box shall bel compactly contiguous to each other, so .that

when the box is cut and scored from a rectangular sheet of strawboard, or cardboard, the waste therefrom is reduced to a minimum. v d

The object of my invention, therefore,

` among other things, 1s to accomplish this desired advantage in the construction of folding paper boxes, and to this end-I take two ieces kof rectangular strawboard, or card- 'l oard, such as are shown in-Figs'. ljand 2,

and cutI and score the same, as shown in the "figures, the :heavy double lines being the cuts and the light vtriple Alines being the scored parts.

' Referring to Figs. 1 and 2, A and A constitute the side pieces of my box, provided on either side with the extension flaps E, G, E', G", respectively, which extension iaps are integral with their respective sides. At

due end of A and A respectively are the end piecesB, B, integral withA and A re.- spectively, and having integral with themselves the extension flaps C andDAand C and D respectively. Atthe opposite-end -of A and A are the binding flaps F, F respectively, "which, when the box is assembled in position, are bent inwardly and are fastened by eyelets, rivets, or any other means, such as adhesive, the flap F being, when the.box is assembled in position, affxed'to-the end of the end piece B, while piece B, as is clearly lillustrated in Fig. 4. It will be observed that theiaps C, 1),.E,

the flap F is affixed to the end of the end s length as their contiguous end or side pieces inner surface of the end piece B, as is shown in Fig. 4, wiere the parts are more clearly illustrated than in Fig. 3,- Fig. -3 representing my improved box when the same 1s 1n a knock down or fiat condition ready for 4shi ment.

n assembling the various parts of my box in nal position, the extension iiaps C, C,`D, D', lare bent inwardly and at substantially right angles with the end pieces B, B, whereby they furnish a strutting support to the sides A, A. sion flaps ofthe sidesv E, E, 7Gr, G', are bent inward the sides A, A', and inasmuch as their -com bined width is that of the length of the end pieces B, B, their exterior edges will close against each other, so as to form a further strengthening strutting support for the Then the exteny at'substantially-right angles with sides. I then take a strip ofstrong paper, shown in Fig. 5, `and designated as H and H', and paste or otherwise secure the same at either end of the end pieces B and B', thus closing and holding in position the exterior flaps E, E', and G, G', as shown in Fig. 5. These strips H, H', afford a convenient and secure method of holding these extension flaps of the sides in position, and, at lthe saine time, when it is desired to openv the box, they can be. readily cut or torn away, I may likewise employ a single strip. to encircle the ent-ire box in place of the two strips H, YH', and secure theA same desired effects. l

kIt will be observed that my box, as finally assembled by the correlation of the various parts, affords a simple, strong and eliicient and economically advantageous paperbox, such as can be shipped in a fiat or knock down 7 condition, and readily' set up and secured in permanent position by simple and eficacious means for holding the parts together.

vWhat I claim as new and desire to secure by Letters Patent isthe following, vizzl; A rectangular folding paper box comprising end and side pieces having extension flaps having their'combined width the same as the width of the side and end pieces,

`turned in extension flaps integral with the sides and bent in and secured to their adjacent end pieces, two binding strips, one provided to hold in position the turned in extensions froln the sides to form the top of the box, and the other provided to hold in position the turned in-extensions on the opposite side of the box toI form the bottom of Ithe box, substantially as described.

2. In a rectangular folding paper box, the combination of two rectan lar side pieces and two rectangular end p1eces,."the respective end pieces and side pieces being integral with each other and the four being secured to each other, extension flaps adapted to fold inwardly at substantially right angles with said sides and said end pieces, binding strips adapted t0 hold in position the said extension iaps from the sides so as to form the top and bottom of the box respectively, substantially as described.

3. In a rectangular folding paper box the combination of the side piece A and endv piece B integral with each other and the v side piece A andthe end piece B' likewise integral with each other, the sides A and A having integral with themselves respectively the extension flaps E and G and E and G', such extension flaps being one-half the width ofthe sides A, A', end flaps F, F', integral with A, and A', adapted to be bent inwardly at substantially .right anglesand secured to the ends of the end pieces B', B,

respectively, two binding strips H, H',

adapted to secureand holdr inpositiomthe extension flaps of the sides E, E', G, G', so as to form the top .and bottom of the box respectively, substantially as described.
