SPECIFICATION forming part of Letters Patent No. 642,121, dated January 30, 1900. Application tiled May 20,1898. Serial No. 681,207. (No model.)

,To @ZZ whom, it 72mg/ concern:

Beit known that l, HERBERT L. HILDRETH, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Folding Boxes, of which the following is a specication.

My invention relates to that class of boxes commonly made of pasteboard, which are so constructed that for purposes of packing and transportation they may be folded iiat and subsequently be converted into the ordinary box forni. lts object is to improve the construction of these devices iu certain particulars, which will be hereinafter more fully pointed out.

ln the drawings lhave shown, in Figures l, 2, and 3, the blanks of which the box is composed, at Fig. 4, in perspective, the section of the box that forms the outer sides and tops, at Fig. 5 the other section of the box, consisting of the inner sides and bottom, and at Fig. 6, likewise in perspective, the whole box formed by engaging the sections illustrated in Figs. 4 and 5 one with the other, the box being open.

The blank A, Fig. 1, comprises the part 1, which is the outer rear side of the finished box, the part 2, which is the box cover or top, and the part 3, which is the top-securing flap. The blank B, Fig. 2, consists of the part 4, which forms the outer front of the completed box, the parts 5 and G, which form the outer ends or end sides thereof, andthe parts 5 ando, which constitute two locking-flaps. The function of these will be more fully explained later. These two parts A and B, put Y together, (see Fig. 4,) form one section of my improved box, which, as is obvious, is composed of the sides and top of the box. My preferred method of securing said blanks together is by means of flaps 1fL and 1b, formed upon the part 1 of the blank Aand pasted onto the end of parts 5 and 6. Obviously, however, these iiaps might be formed upon the parts 5 and 6 and pasted on the part 1, or the blanks A and B might, although not so economically, be cut from a single piece of stock, either the part 5 or the part G being made integral with the part 1, and thereby only one joining-flap being required.

The blank O contains the portion 7, which forms the bottom of the Finished box, and the portions S, 9, 10, and 11, which respectively form the inner parts or faces of the ends and inner front and rear sides of the box. The parts 10 11 are each provided with a locking flap, (marked 101L and 11a, respectively.)

The blank O forms the second or, as it might be termed,the in ner section of myimproved box, the other or outer sect-ion being, as pointed out above, formed by uniting the blanks A and B.

It will be seen that both of the box-sections can be folded into a flat form. This is of great importance, as it enables a relatively large number of the box-sections to be packed into a small compass for shipment, and any party can readily cause each section to assume its proper form for use and assemble said sections to provide a complete box.

ln assembling the sections that one formed from the blank C is placed within the other, (formed by the blanks A 13,) and the flaps 10*L lla of said inner section are caused to overlap the flaps 5n 6a of the other box-section, as shown clearly in Fig. 6. Vhen l[he parts have been thus assembled, although no rigid or permanent connection is established between the two sections, it becomes practically impossible when the box is filled and the cover folded down and secured by inserting the topsecuring flap 8 into the pocket formed between the parts 10 and 4 towithdraw or separate one part or section of the box from the other. At the same time the four ilaps 5a, 6, 10, and 11' form a border about the open end of the body of the box and presenta neat iinish when the top is open and the contents exposed.

The parts 8 and 9, which l have heretofore spoken of as constituting the inner end sides of the box, are preferably, although not necessarily, made as wide as the corresponding parts 5 and 6 of the outer box-section. The

function of these parts 8 and 9 is mainly to close the joint which would otherwise occu r bctween the bottom and the end sides of the box. I believe it,however,to be advantageous to extend them up to the same height asthe other corresponding portions, both for the sake of uniformity and also because I thereby IOO vss

obtain a box which has all four sides double, and hence is of correspondingly-increased stiffness.

From the above description and the drawings it will be seen that I have provided a box consisting of two independent and separately-formed sections adapted to be detachably connected, each section being of such form as to be capable of folding upon itself into a practically fiat condition.

The advantages incident to such a construction in comparison with boxes of the same general character and for analogous purposes heretofore proposed will be apparent. As all of the parts required to be permanently connected by pasting or other similar means are connected in forming the sections, the party desiring to use the box need not be skilled nor have to employ any special means for securing the two sections together.

I am aware that prior to my invention of the box herein illustrated and described it has been proposed to make a box from two paper blanks properly folded and secured together to form the vwalls of the box; but in all of the earlier constructions with which I am acquainted it was impossible to separate the completed box into two independent sections at any time after they had once been assembled-that is, in the earlier construction above referred. to the sections or blanks from which the box was formed werevpermanently secured ,together and could not be separated without damaging and destroying the further usefulness of the article. By my invention, however, it will be seen that the two sections (one formed by the blanks A B and the other by the blank C) are entirely independent and distinct one from the other, and there is no such permanent and fixed connection between said sections as prevents their separation at any time.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The herein-described folding box having double side and double end walls and consisting of two independent sections, onesectionV forming the outer side and end walls and the cover for the box and the other section forming the inner side and end walls and the bottom of the box, the latter section being fitted within the first-named section, and said sections having at their upper edges means for engaging with each other whereby the sections are held together when the box is in use.

2. A folding box having double side and double end walls',com posed of two distinct and separable parts, one part comprising the outer side and end walls and the top, and the other part the inner side and end walls and the bottom of the box, the said last-mentioned part being fitted within the first-mentioned, the side walls of one part being provided with flaps, and the end walls of the other part being provided with similar flaps adapted to interlock therewith when the two parts are titted together, for the purpose set forth.

3. A folding box having double side and double end walls consisting of two detachable and separately-constructed sections, one section forming the outer side and end walls, the cover of the box and a flap on the front edge of said cover, and the other section forming the bottom of the box and the inner side and end walls, the end walls of the first section having inwardly-extending flaps, 5a, 6, at their upper edges and side walls of the second said section having at their upper edges inwardly-extending fiaps, 10, lla, adapted to rest on the flaps, 5, 6, and to support the second section within the first-mentioned section.

4. A folding box of the character described composed of three blanks,one forming the top and one of the sides of the box, another connected to that aforesaid and forming the other side and the ends of the box, and the third forming the bottom of the box, the two lastnamed blanks being provided with flaps adapted to overlap and connect said parts together.

5. The herein-described box embodying in its construction three blanks, A, B, C, the blank A forming the'back side wall, l, and the cover, 2, the blank B forming the front wall, 4, and end walls, 5, 6, and adapted to be secured firmly to the blank A, the end sections 5, 6 of the blank B having the inwardlyextending fiaps, 5a, 6a, at their upper ends, and the blank C forming the bottom of the box and having upwardly-extendin g portions, 10, l1, terminating in fiaps, 10a, lla, which engage with the aforesaid flaps, 5a, 6a.

6. The herein-described box having double sides and embodying in its construction three blanks, A, B, C,.the blank A forming the outer part, 1, of the back side wall and the cover, 2, which is provided with a retaining-flap, 3, the blank B forming the outer parts of the front side and end walls and adapted to be firmly secured to theblank A, the end sections, 5, 6, of the blank B having inwardly-extending flaps, 5, 6a, at their upper ends, and the blank C forming the bottom of the box and the inner parts of the side and end walls thereof, the inner parts of the side walls having at their upper ends inwardly-extending flaps, 10a, lla, which overlap the aforesaid flaps, 5, 62.

In testimony whereof I have hereunto subscribed my name this 13th day of May, 1898.
