10 Claims.

This invention relates to a container and, more particularly, to a box or carton of the tray type.

An important object of the invention is the provision of such a container which may be formed in a single piece from a single-faced board and which will provide a construction having both its inner and outer faces finished by the single facing.

Another object of the invention is the provision of a tray-type box or carton which may be shipped in a flat condition and which in its erected form affords a convenient and attractive display package.

Another object of the invention isthe provision of a device of the character described above which may be, as desired, equipped with an integrally attached cover.

A further object of the invention is the provision of a box which may be shipped flat and set up by the user and which, when set up, provides self-contained locking means insuring the integrity of the erected structure.

Referring now to the drawings and, more particularly, to Figures 1 to 6 thereof, the carton constructed in accordance with my invention comprises outer and inner bottom walls [0 and I l, side walls [2 and I211, and end walls comprising outer and inner wall members l3 and I4 of which the wall member I4 comprises the flap integrally connected with the outer wall member [3 at a crease fold l5. It will be noted that in the erected form of the box, as shown in Figure 3, all the outer surfaces at boththe interior and exterior of the box are formed by a common surface of a blank forming Figure 1 so that if this surface of the blank is a single finished surface folded of single-faced cardboard, a completely flnished structure is provided, thus enabling the use of a relatively cheap material. 7

As more clearly seen from Figure 1, the side wall I2 serves to connect the outer and inner bottom walls l and H, the connections being in the form of crease folds indicated at IS. The outer edge margin of the inner bottom wall is connected to the side wall l2a by crease fold I1,

and to the outer edge margin of the outer bottom wall a flap I8 is connected by crease fold IS. The end portions of side walls l2 and Ho have flaps 20 attached thereto. For purposes of display, it is desirable that the side walls I! and l2a. in the erected structure be sloping, and for this reason itjs necessary that the flaps 20 be made trapezoidal, as shown.

In the primary construction of the box, the inner surface of side wall |2a is pasted, or otherwise secured to the outer surface of the flap l8, as more clearly shown in Figure 5. The side walls l2, l2a and the bottom wall II are made of such height that when this connection has been made the box may be folded flatly, as shown in Figure 2 and the typical section forming Figure 15, and thus may be conveniently shipped. This involves merely a simple computation to insure that the width of the inner portion I I connecting adjacent edges of the side walls l2, He should be equal to the width of the bottom wall Ill. Flap H, in addition to forming an interior facing for the end walls, likewise serves as a locking means to hold the interior bottom in proper position and to mutually interlock therewith to prevent either displacement of the bottom or of theflap. To this end, the ends of the inner bottom portion II are made somewhat shorter than the length of the outer bottom and the ends of this section are provided centrally with slightly projecting extensions 2|. In the form at present shown, the inner surface of the bottom wall is dished in a smooth curve. The tongue or flap I4 is so constructed that its edge corners 22 are spaced apart a distance slightly greater than the distance between the portions of the bowed inner wall with which they coact so that they must be sprung back of this inner wall, as more clearly shown in Figure 5, the abbreviation of the inner wall section providing space for their reception. The extensions 2|, however, will engage against the inner surface of the outer end wall member l3 and thus the central portion of flap M will overlie these extensions and hold the central portion of the inner bottom firmly in position.

In. erecting the folded box structure of Figure 2, it is simply necessary to apply sufficient pres-- sure to cause.the side walls to erect, fold in the end flaps 20 of the side walls, and then fold the end flap ll downwardly and inwardly to its locking position.

In the form of invention shown in Figures to 14 inclusive, the inner bottom wall, indicated at Ila is subdivided by folding scores 23 into a central panel 24 and side panels 25, the center panel overlying flatly the outer bottom I0 of the box and the panels 25 forming inner side walls beyond which the upper edge corners 22a engage. The flap a is notched, as at 26 to receive the extension 2la so that the free edge of this flap may engage entirely against the bottom of the box. Additionally, the extension 2| a is provided with a flap 21 to extend between the inner and outer end walls and thus further increase the security of the lock maintaining the box in its erected position. By varying the proportions of inner side walls.

panels 25 and the panel 24, the inner wall may be either sloped, as shown in Figures 11 and 13, or be made perpendicular as in Figure 14. The formation of flap I will naturally have to be varied to conform to the angularlty of the inner side walls, and in all cases will be provided with extension portions 220 to engage behind such It will be noted that in the form of invention shown in Figures 1 to 6, the upper portions of the inner bottom actually form inner side walls for the box. Attention is directed to the fact that utilization of the notch 25 in the inner-end-wall-forming flap enables the entire free edge portion of this wall to engage behind the end edges of the inner bottom or inner-bottom and inner-side-wall-forming section of the box, thus further insuring the integrity of the locking mechanism.

In Figures 7 to 9 I have illustrated the application of the construction shown in Figures 10 to 14 to the box design illustrated in Figure 3.

In Figures 16 to 20 I have illustrated a method of applying an integrally attached cover to the box, this being particularly applicable in connectionwith boxes of the type shown in Figures 10 to 14, although adaptations thereof might well be employed with the construction of any of the remaining figures. In these figures the walls I2, I21: instead of being attached to opposite sides of the inner bottom wall panel are attached to opposite sides of the outer bottom wall panel II. The flap l8a employed in connecting the side edges of the main blank is disposed at the free edge of the panel Ila. The free edge of the wall no corresponding to the wall l2a of the constructions hereinbefore discussed has a flap cover 28 connected thereto by a crease fold 29. In this form of box construction the erection is identical with that discussed in connection 'with the remaining forms.

In the form of invention shown in Figures 21 to 28 inclusive, I have illustrated a method of constructing a box in accordance with my invention without resorting to any gluing or attaching devices. Such a box may be either shipped flatly, as illustrated by the blank plans of Figures 21 and 24, or may be folded for more compact packing, as illustrated in Figures 23 and 26. In these figures the inner bottom section instead of being formed as anintegral structure is formed in two sections 30 the outer edges of which are provided with projections 3| adapted to interdigitate when the sections are brought into combined relation, as illustrated in Figures 22 and 25. The end edges of the sections 30 each bear one-half of a tab 32 corresponding to, the tab 21 of the construction of Figure 10, for example, these half-sections combining, as more .clearly, seen in Figures 22 and 25 to produce a ormay include a plurality of panels 30a, 30b pro ducing a distinct inner side wall as in the case of the construction shown in Figures 13 and 14.

In the form of invention shown in Figures 29 to 33, a further and important modification of my invention is illustrated. In this form of the invention the inner bottom wall is so arranged as to form a platform in which, by the provision sert.

of cut-outs, definite location of contained articles 33 may be secured after the manner of the ordinary perforated trays formed as-a separate in- In these figures, llb indicates the inner bottom wall comprising a. main panel 34 perforated to suit the articles to be stored and side panels 35 which form the inner side walls of the box. As usual, this section llb is abbreviated in length, having projections 36 at the central portion of its end edges. Secured to these projections are tabs 31 which are made of a height equal. to that at which it is desired to space the inner bottom wall from the bottom wall I0. In erection of a box of this character, the tabs 31 are bent downwardly and in the completely erected structure have their free edges resting upon the inner surface of the outer bottom wall It, as more clearly shown in Figures 31 and-32. As in the constructions hereinbefore considered, the inner-end-wall-forming tabs 38 are notched to receive the extension 36, thus insuring against any possible transverse displacement of the inner bottom wall and permitting engagement by the entire free edges of the inner end walls behind the end edges of the inner bottom wall.

In each of the constructions hereinbefore described, it will be noted that board having but a single finished surface will sufilce to produce a box both interiorly and exteriorly finished.

Since the constructions illustrated are capable of considerable modification without departing from the spirit of my invention, I do not wish to be understood as limiting myself thereto except as hereinafter claimed.
