The invention relates particularlyto a box or carton which may be used to contain any suitable or desirable article.

The. device may be made of a single piece of material suitably cut and folded and even without pasting or other holding means.

An especial feature of the invention is. the cover or closure member.

In the accompanying drawings a specific embodiment of the invention is shown. Figure 1 is. a plan view of the blank from which the device may be folded. Figs. 2, 3 and 4 are perspective views of blanks in successive states of being partially folded to form the device. Fig. 5 is. a perspective view of the completed device with the cover or closing member open. Fig. 6 is a perspective view of the completed device with the cover or closing member in closed position. Fig.

7 is a perspective view of a completed device in another specific form.

The device and the blank from which it is made, as well as the various elements or segments thereof, may be changed as to size, shape, proportions and cooperation in various ways, without departing from the invention, but a specific form will be explained in detail in connection. with the drawings;- so as to fully disclose the invention.

The specific embodiment shown is triangular inshape and as shown the cover forms the front or top side of the device but it may be turned and used in. any other position. Without limiting the use or construction of thedevice or the position of the various'members but for convenience of description arbitrary terms of location will be employed. One wall will b referred to as the back wall, irrespective of Where it may be positioned, and likewise walls and members will be referred to as right and left as they appear on the drawings. The various sections of the blank which make up the carton are of various sizes and shapes, some being longer in one direction and some in another, but for clearness of description the terms length and ends may be used with respect to the extent from top to bottom as shown in Fig.1, whil width or sides may be used with respect to extent from side to side as shown in Fig.- 1-. In Fig. 1 the blank from which the carton is to be formed is shown as a single sheet of cardboard or other suitable material. The solid lines; of the drawing; show lines on which cuts are made. The dot nd dash lines show lines on. which folds are made and these may be scored 01: otherwiseprepared for easy and accurate fold: ing; or bending. The variousportions of the blank maybe referred to, as members.

Themember I0. is, to form the back of the finished carton-and at its: right side, may beattached the outer right wall member H, to which is attached the: right inner wall member 12. To

' the left of the back wall member [0 is attached the outer left wall member 13 to which is attached. the inner left wall member l4. To'the. top of the back wall member is attached the top or cover member l5 at either side of which are attached wing members I6, I! which are pro.- vided at their outer ends with teeth or serrations I8, IQ. for a purpose to be hereinafter explained. To the top end of the cover i5 is at.- tached a, tab or finger member 20. At the bottom edge of the outer right wall member H. is attached an intermediate bottom wall member 2| and attached to the, bottom of the outer left. wall member I3 is. an intermediate bottomwall member 22. One of the interlocking members such as 2i may be cut away or curved as at 23 so as to facilitate interlocking.

The, first step in forming the. carton may be as shown in Fig. 2 where the members l2 and M are folded over onto. thev members II and l3 respectively, and the wing members I6 and I1 may be turned up. The combined side members l, [2 and, I3, It may then be turned up as shown in Fig. ,3, and the members 2! and 22 caused to interlock.

At the bottom of the back memben I0 is at,- tached an outer bottom member 24 which may now be turned upwardly or forwardly to lie as shown in Fig. 4 in close contact with the interlocked members 2 l, 22 and coverand protect the interlocking joint and form a smooth outer surface. The member 24 may be cut away at its sides as at 25 so that in the finished box as shown in Fig. 6 the sides of the outer bottom wall member 24 may not be visible.

. At the front or bottom edge of the member 24 is attached the inner bottom panel wall mem-- ber 26 which has on each side at its bottom end side tabs or Wings 27 which may be turned downward as shown at Fig. 3. The member 26 may now be turned inward to overlie the intermediate bottom member 2|, 22 as indicated in Fig. 5, inv which position the wings 21 will rest against the inner side Wall members i2 and IA.

The inner bottom member 26 carries at the sides of its upper or front end teeth or serrations 28 and the top. or cover member l5 may now be bent forward inserting the wings. l5, l1 between the edges of the inner side walls l2 and [4 so that the teeth or serrations i8, i9 carried by the wings H5, ll will engage the teeth or serrations 28 and so tend to hold the cover closed and in place. The tab 29 will rest, against. the front edgev of the bottom as indicated in Fig. 6 and may serve as means for lifting the locking teeth out of engagement and also as a handle for raising or opening the. cover member l5.

A tab as may be cut. and turned, up in the inner bottom wall member 26 as shown in Fig. 5. and form a stop or positioning means for a bottle or other device (not shown) which may be contained in the carton.

The material of which the device is made may be somewhat resistant to bending so that it has a tendency to resume its unfold or fiat position. Thus the inner side walls l2 and I4 press against the inner bottom wall member 26 and tend to hold it in place. 7 against the inner wall members l2 and I4 and tend to hold the inner wall members in close contact with the outer wall members H and I3 and also hold the bottom member 26 snugly in place. When the cover It is in place the wings I6 and I! may tend to spread and, by pressure contact with the side wall members l2 and I4, tend to hold the cover in closed position indicated in Fig. 6. In order to allow it to assume its proper position the cover member it may be slightly narrower than the back wall member ill. The inner bottom wall member 26 may be slightly narrower than the combined interlocking members 2! and 22.

It will be observed when the carton is open as shown in Fig 5 or closed as in Fig. 6 no rough or cut edges are shown. A neat attractive finish is furnished by exposing at the sides the curved folded edges between the members l l and I2 and between the members I3 and I4 and at the bottom the curved folded edge between the members 24 and 26.

The succession of folding the various members described may be a convenient order, but it is not essential to the present invention since the parts maybe folded and brought into contact with each other in other orders to produce the carton.

. Fig. 6 shows a carton made from the blank shown inFig. 1. By properly varying the shapes and sizes of the elements cartons of other shapes and sizes may be produced, one of these being shown-in Fig. '7.
