UNJTED STATES PATENT OFFICE COMPANY, OF LITITZ,

OF LITITZ, PENNSYLVANIA, ASSIGNOB '10 SIMPLEX PAPER BOX PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA COLLAPSIBLE EXTENSION TOP AND BOTTOM BOX Application filed May 24,

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawings which illustrate one embodiment of the same, and a slight modification thereof, selected by me for purposes of illustration, and the said invention is fully disclosed in the following description and claims.

My invention consists in a knock-down folding box of the kind in which the top and bottom sections of the box are provided with portions of greater length and width than the interior of the box when in contents receiving condition, forming an outwardly extending portion projecting beyond the sides and ends of the box, and forming what is known in the trade as an extension top and bottom box. Such boxes are usually made up in permanent form, the exterior portions being decorated or covered with decorated paper, and the top portion is frequently padded, and the completed boxes therefore occupy a very considerable space in transportation, and in storage. The object of my a present invention is to construct a box of this character WhlCh can be very lnexpenslvely produced as a knockdown box capable of being shaped flat and stored in that condition, thus occupying a minimum amount of space, and which can be instantly folded into and locked in its contents receiving condition when it is desired to use it for the delivery of candy, or any other merchandise for which it may be found to be desirable. A salient feature of my invention consists in the formation of the extension portions of the top and bottom sections of the box separate therefrom and united to the central portion of a folding or knockdown box blank, thereby gradually simplifying the manufacture of these boxes and cheapening the cost of the same, without impairing the appearance of the box, and greatly increasing the stability and sturdiness of the box structure.

This construction also facilitates the decoration of the exterior of the box, .-permitting portions of the decorative scheme to be printed directly upon exterior portions of the folding blank in general conformity to the decorations on the cover paper 1928. Serial No. 280,177.

secured upon the extension top, for example, and by properly matching the color scheme of the decorations printed on the folding blank portions with which the boxes may be' produced in large quantities, and also facilitatmg the application of the necessary printed matter to indicate the contents of the box and the original thereof.

The body portion of the top, bottom section of the box, is 0 blank properly scored and capable of being partially folded and glued where necessary,

and also the rmed from a to prepare it in the knockdown condition. I prefer to use a blank of the kind illustrated 1n my former application for Letters Patent of the United States, Serial No. 146,079, filed November 4th, 1926, and Serial No. 224,859, filed October 8th, 1927, either of which is admirably adapted for the purpose, and in this instance I have shown, in Fig. 4, a box blank of the kind'illustrated in my last mentioned prior application. This blank is formed of suitable card-board, paste-board, or other sheet material which can be creased and bent or folded, which is cut by suitable dies or otherwise, and scored or creased, as shown in Fig. 4. The blank comprises, preferably in one piece, a rectangular central body portion, 1, having main side flaps, 2, 2, at opposite sides thereof, separated therefrom by creases or lines of fold, 2, the side flaps being rovided with auxiliary or reinforcing side aps, 3, 3, separated from the side fla s, 2, by creases or lines of fold, 3 The rein orcing or auxiliary side flaps, 3, are of substantially the same width as the sideflaps, 2, and are provided at their outer edges with body engaging flaps, 3 separated from the flaps, 3, by creases or folds, 3, and provided at opposite ends with mitered portions, indicated at 3*, which I term the bottom locking portions. The reinforcing flaps 3 are also slightly cut away at each end, as indicated at 3", to form side locking portions, as hereinafter described. At each end of the body portion 1, is an end flap, 4, separated therefrom by a crease or line of fold, 4 and being of the same height as the side flap, 2, and beyond each end flap is a reinforcing flap, 5, separated therefrom by a crease, 5*. Each of the reinforcing end flaps, 5, is of the same height as the adjacent end flap, 4, and is provided at its outer edge with a bottom engaging locking flap, 5 separated therefrom by crease, 5,and provided at its opposite end with mitered locking portions, 5, for engaging the locking shoulders, 3 as hereinafter described. Each of the side flaps, 2, is connected with the end fia s by corner sections, indicated at 6, divided y a diagonal crease, 6*, into two flaps, 7 and 8. The locking flaps, 5, are also provided at each end with looking projections, 9, adapted to interlock with the cut-away portions, 3, of the auxiliary side flaps, 3. It will be understood that the auxiliary side flaps, 3, are folded over upon and adhesively secured adjacent to the side flaps, 2, which will bring the flaps, 3", upon the body portion, 1, as indicated in dotted lines, in Fig. 4, and said flaps, 3", are adhesively secured to the body, 1. I have indicated by shading in Fig. 4, that the inner faces of the flaps, 3 and 3 are to be gummed, but obviously the parts could be secured together in any other desired way. The corner sections, 7 are also adhesively secured to the adjacent end flap, 4, as indicated in dotted lines in Fig. 4, and I have shown said fla s, 7, shaded to indicate adhesive material t ereon, althou h it is to be understood that they may be ot erwise secured.

In Figs. 2 and 3 I have shown the extension top, for example, of the box, which comprises in this instance, a rectangular piece of cardboard, indicated at 10, which in this instance is provided with a similarly shaped sheet of padding, 11, of any suitable material, held 1n place by an exterior cover, 12, of paper, the marginal portions, 12 of which are pasted upon the inner face of the card-board, 10. The paper cover, 12, is decorated with any desired design, and the paper sections for these extension tops may be printed in any desired manner to indicate the contents of the box, and the origin thereof.

The outer faces of the side flaps, 2, and

reinforcing side flaps, 3, and of the end flaps, 4, and locking flaps, 5, are preferably printed in a decoration, as indicated, for example, in Fig. '9, which harmonizes "with the color scheme and decorations used on the cover paper, 12, for the extension top, so that when the blank is in folded position, as shown in Fig. 9, the exterior of the lateral portions formed by the side flaps 3, and end flaps, 4, as well as the interior faces thereof, will present a decorated and harmonious appearance with respect to the covering for the extension top. It is not necessary to print decorations on the blanks except on the side and end flaps, 2 and 4, and I prefer to include the decoration of the infolded reinforcing side flaps, 3, and locking flaps, 5, as it produces a more pleasing appearance when the top is removed from the lower portion of the box, and at practically no additional expense as it can all be accomplished by a single printing. It will be understood, of course, that the decoration of the side and end flaps of the folding blank may be accomplished by covering or adhesively attaching decorated paper portions instead of printing these portions of the blank, but obviously the printing thereof is much cheaper, and in practice it is found to be equally satisfactory from the standpoint of appearance.

The blanks for the folding box portion, for the top of the box, formed as shown in Fig. 4, will be folded and glued up so as to occupy the position indicated in Fig. 5, that is to say, the reinforcing side flaps, 3, will be adhesively secured to the side flaps, 2, and the body engaging side flaps, 3", will be adhesive- 1y secured to the body, 1, and the united side flaps, 2 and 3, will be folded over upon the body, 1, and the corner flaps, 7, will be secured to the end flaps, 4, leaving the blank in a very flat and compact form. The folded blank is then adhesively secured to the bottom of the extension top portion, 10, indicated in Figs. 2 and 3, so that the latter shall proect substantially equally beyond all of the edges of the body, 1, of the folding blank, as clearly indicated in Fig. 5. The upper member of the extension top and bottom box is then in condition for shipment.

Where the box is deslgned to be a truly telescopic box, that is to say, one in which the upper section telescopes over the side portions of the lower section, the'lower box member is formed in exactly the same manner as the upper box, except in the following particulars. As the lower box section is practically concealed except forv the extension bottom portion, indicated at 110 in Fig. 9, it is usually deemed unnecessary to provide any decoration for the extension bottom, or for the lateral portions'of the box, indicated at 102 and 104, in Fig. 9. The box blank therefore need not be printed at all, and will be made up in exactly the same manner as that previously described with reference to Figs. 4 and 5, except that its dimensions will be sufficiently smaller than those of the corresponding part of the box top section, as to enable it to fit neatly and telescopically within the same. The extension bottom, 110, is formed of a piece of card-board of substantially the same size as that used in the extension, top, and is preferably covered with a paper cover, indicated at 112, which may be plain white or glazed paper, or it may be a decorated paper to conform with the sides and top, if desired. I also prefer to provide the usual lace-paper flaps, indicated at 113, which may be adhesively applied to the inner faces of the infolded reinforcing side pieces, 103, as shown in Fig. 7, which illustrates the knockdown position of the folded plank, and also in Fig. 8, which illustrates the contents receiving position of the same.

It will be understood that the bottom box section will also be made up and folded and glued in-the manner illustrated in Fig. 5, so that the entire box can be readily shipped flat and kept in that condition until it is desired 0 use the same. When it is desired to use th box, each section canbe quickly placed in contents receiving condition, by simply bending up the end portions 4, (see Fig. 5) which, through the connected corner flaps, 7, 8, will raise the side'flaps, 2, 3, into vertical position and by bending the locking flaps, 5, over upon the end flaps, 4, which can be readily and simultaneously accomplished by the operators thumbs, the side locking portions, as, 9, Figs. 4 and 5, will be interlocked with the cutaway portions, 3, of the auxiliary side flaps, and the bottom engaging locking flaps, 5", will be brought into position to cause their mitered locking edges, 5, to engage the mitered locking edges. 3, of the flaps, 3", as

clearly illustrated in Fig. 9 in the upper por-- tion thereof, thus constituting a double lock for the end flaps, and securing the box rigidly in the contents receiving condition.

' cated at opposite ends with the two hands, and simply raising the end folds to vertical position and folding in the locking flaps with the thumbs. This feature is broadly covered in my former application Serial Number 146,079, and the specific form of the folding blank portion is covered by my former applications hereinbefore mentioned, and these features are not herein claimed except in connection with the extension top and bottom type of box.

It is also to be understood that my invention is applicable to an extension top box of the partially telescopic type, such as is illustrated in section, for example, in Fig. 10. In this instance the top and bottom sections of the box, indicated generally at A and B, in this figure, will be constructed exactl as previously described with reference to igs. 1 to 6, and will both be made according to the same identical dimensions. In this case the outer surface of the box members, A and B, will be decorated, that is to say, the side and end flaps thereof, but it will not be necessary to decorate the extension bottom portion of the box member, B. In assembling the parts of this type of box, the box members, A and B, which will be kept in the fiat folded form, will be brought into contents receiving position in the same manner as previously described and a rectangular cover, indiwill be placed within the bottom box member, B, and will be of a width sufiicient to extend above the side portions of the box member, B, so that the side portions of the box members, A, may be telescoped thereon, in a well known way.

Aspreviously stated, my present invention provides an extension box which can be made up in the knockdown form very cheaply, and

may be shipped flat and kept in the flat condition until the moment of use. As the bottom portions are usually not decorated at all, they might be made up in large quantities in advance of orders'and with great economy, and used in connection with the top members, which may be decorated to order to suit the tastes of diflerent customers, as to design, lettering, etc., and merely by printing the covers, 12, for the box tops, in the particular design and letter required, which may be one of many designs in harmony with the color scheme used in the decorations of the side portions of the top section of the box. Moreover, the folding blank portions of the top sections of the box may be made up into the knockdown condition in great quantities, if desired, and held subject to orders to fill which it will only be necessary to rint the covers for the extension top, apply t e covers thereto, and attach the covers to the folding blan-kportions of the upper sections of the 5 boxes. This construction, therefore, enables the box manufacturer to produce these boxes with great economy and at the same time carry out the special decorations desired by individual customers;

What I claim and desire to secure by Letters'Patent is 1. :As a new article of manufacture, a knockdown box section,comprisi ng a main body, integral side andend flaps and means for detachably locking them in set up position, the outer faces of. the side and end flaps only being de c0rated,'and a separately formed extension member,.of greater transverse and longitudinal diameter than the main body,

decorated on its outer face only and permanently united to said main body with its Undecorated face. in engagement with the undecorated' outer face of said main body.

2. As a new article of manufacture, a

knockdown box section comprising a main body, integral side and end flaps and integral means for detachably locking them in set up position, the outer faces of the side and end flaps having decorations imprinted directly 30, thereon, a separately formed extension blank of greater transverse and longitudinal diameter than the main body and a decorated covering fabric extending over the outer face oftheextension blank and secured to the under face thereof, said extension blank being permanently secured to the outer face of-said main-body coaxially thereof. 3. As a-. new article of manufacture, a knockdown box section comprising a main 40 body, integral side and end flapsv and integral means for detachably locking them in set up position, and a separately formed eX- tension-blank of greater transverse and longitudinal dimensions than the main body, said -extension' blank being permanently secured to the outerface of said main body to provide extensionsbeyond the sides and ends thereof. In testimony whereof I afiix my signature. RALPH A. GROSS.
