Carton.

Application filed September 13, 1905. Serial No. 278,310.

To all whom it may concern:

Be it known that we, John H. Marsh and Joseph J. Lanzit, citizens of the United States of America, residing at Chicago, in 5 the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cartons, of which the following is a specification.

Our invention relates to improvements in ,10 cartons and is fully described and explained in this specification, and shown in the accompanying drawings, in which

Figure 1 is an elevation of the blank from which our improved paper,box is made; Fig. 15 2 is a view snowing the first portion of the wrapping operation; Fig. 3 is a perspective view .showing the device at a subsequent stage of the wrapping; Fig. 4 shows the device when still further wrapped; Fig. 5 20 shows the device completely closed; and

Fig. 6 is a section in the line 6—6 of Fig. 5.

Referring to the drawings, it will be seen that the blank has a long rectangular central portion.divided by score marks into sec25 tions, A, A¹, A², A³, and, A⁴, the section, A⁴, preferably having its corners cut off and naving at its free end a small locking flap, A®. In forming our improved box about a solid body, as is ordinarily done, the body is 30 laid oh tne section, A², the section, A³, being brought up on one side of it, the section, A⁴, lying above it, and the locking flap, A⁵, being turned down as illustrated in Fig. 2.

. The body is then rolled oyer from the posi35 tion shown in Fig. 2 to the position shown in

Fig. 3, so as to bring the section, A³, on top . and the section, A², on one side. This lays the section, A¹, underneath the package, and outside the locking flap, A⁵, and thereupon 40 the section, A, is swung up into a vertical position outside the section, A⁴. When the parts are in this position, it will be seen that the section, A³, is absolutely locked against outward movement witji respect to the 45 package, and that it is only by first moving out the sections, A, A¹, that the section, A³, can be swung away. These sections are in practice locked by the end flaps of the package, so as to make any such movement of 50 the sections, A, A¹, impossible, and, as a result, the structure is firmly held in position without the use of glue. The end flaps referred to consist of two inner flaps, B, on each end of the package, and a single outer , flap, B¹, oil each end of the package, each of 55 the flaps, B¹, having a short bent end, or .'tongue B². In practice, the inner flaps are swung in from opposite sides of each end and are, consequently, placed on alternate sections of the blank, so that when the box is 60 folded up, they will lie opposite each other. The outer flaps swing over the inner flaps at right angles thereto, and the bent ends of the outer flaps swing in over the edges of the inner flaps, locking them in position. In 65 order to get the best locking effect, we prefer to have the inner flaps on the sections, A, A², of the blank and to have the outer flaps so arranged that when the box is completed, one outer flap shall hinge on one edge of the box 70 and the other on the diagonal opposite edge.

It will be seen that when the end flaps are swung in as illustrated in Fig. 4, the sections, A, and A¹, which operate to hold in the sections, A⁴, and A⁵, of the blank are firmly 75 locked down to the package by engagement of the end flaps, the outer flaps at each end embracing the inner flaps on the section, A, and thus preventing, movement thereof. This type of box can be assembled with ex- 80 treme rapidity and is especially desirable, and is, in fact, particularly designed, for use in wrapping butter, cheese, and the like. When used for this purpose, the pasteboard will preferably be paraffined on the inside. 85

We realize that considerable variation is possible in the details of this construction, and hence do not limit ourselves to the specific form herein shown and described.
