BOX.

Application led October 23,1922. Serial No. 596,268.`

To all whom 'Zt may concern:

Be it known that I, PAUL A. DINsMooR, a citizen of the United States. residing at Lawrence, in the county of Douglas and State of Kansas, have invented certain new and useful Improvements in Boxes; and I do declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this,

specification. This invention relates to boxes and particularly to fiber boxes used for transportation of canned goods although the invention is not necessarily confined to boxes used for any particular purpose.

The weakest points on suchl boxes are where the board has been lweakened bv scoring it to make the fiaps. Therefore, I have provided means for reinforcing the box at the flap connections orscoring. This is .ace complished by pasting strips of reinforcing material on the insiderwalls of the box so that when the fiaps are folded into sealing position, the strips will be concealed.

There are two very important advantages resulting from the application of the strips on the inside of the box. The first is that the material of which the'strips are made is not put under tension. If the strips were put on the outside of the box when the blanks are formed. just as soon as the flaps were folded over the reinforcing strips would be put under tensiony andl there would be a tendency for either the strips to pull away from the box or else to have their fibers weakened to the point of breaking. Second, if the strips are put on the outside of the box, they are weakened by abrasion against other boxes. the floor and side walls of the freight car, during transportation the strips is a very important and handling, as well as being subjected to.

`in-connection with the accompanying drawings, in which-,-

Fig. 1 is a perspective view of a box constructed in accordance with my invention, part being broken away to show the floor or bottom fiaps. 1

Fig. 2 is a fragmentary, sectional view through a portion of the box, showing how the strips are applied, and

Fig. 3` is a fragmentary view of a box showing a can supported upon the strip.

The box can be formed from a blank of ordinary construction. The box in Fig. 1 1s shown as consisting of the side walls 1 and 2, the

end walls

3 and 4, the

side fiaps

5 and 6 and the end flaps 7 and 8. Fla s corresponding to 5, 6, 7 and 8 are on 't e bottom edges of the

walls

1, 2, 3 and 4. One en d wall is secured to a side wall in any suitable manner but for convenience the fastening ris here shown as a pasted strip 9 applied in the usual way. Obviously, however, any of the known method of fastening;y may be substituted for the strip 9. The materialof which the box proper is constructed 1s preferably fiber board, which is corrugated so as to make each liner form a cord or truss, the completed board being in the nature of a truss. In laminated or solid fiber board the bending strength is almost entirely contained in the two outer plies, hence it is important that the inner ply of a solid fiber board be protected, this belng possible by the application of the

inner strips

10, 11, 12 and 13 applied to the solid fiber board box, the broad result being the same as in the corrugated board.

If one of these cords is cut, the box is materially weakened so it is an important feature of my invention that means is provided to prevent the severing or breaking of the cords or corrugations of the box by the chines of the metal cans which are usually ship ed in them.

T e reinforcing strips maybe applied at the same time that the plies 1n solid fiber or the corrugated sheet and the facing sheets in corrugated board are being pasted together; or after the box blanks have been cut, before they have been scored; or if comparatively thin reinforcing strips are used,

.after the blank has been scored. The reinforcing stri s are indicated at 10, 11, 12 and 13 for rein orcing the connections between the

flaps

5, 6, 7 and 8 and the

walls

1, 2, 3 and 4. Corner reinforcements 14 may be provided at the respective corners if desired, and when so added, in addition to protecting the box liners against'cutting or breaking, these strips applied at the corners increase the tiering strength; that is,(to strengthen the box against collapsing when Weight is piled on it. I have shown side iaps and 6 and end flaps 7 and 8 at the top of the box, it being obvious that similar fiaps are at the bottom `of the box and lthat these flaps are reinforced with correspondingstrips.

In Fig. 2 it will be assumed that the side wall 1 carries a side iap 5, the scoring 15 being reinforced by Athe'strip 10. When the strips are put on "the inside of the box, the scoring or groove formed at 15 will conform the strip to the box blank. Then as the flaps are bent over to closing position, the bend at the longitudinal center of each strip will be on a relatively short arc so thatthere will be no stretching or stressing of the fibers of which the strip is composed,

The bottom strip which according to Fig. 3 would correspond to the strip 13,'is in Fig.

3 designated 13. lIts lateral portion resting ,on the bottom ofthe box will serve as a mator reinforcement for the chine 16 of the metal can 17 so that it will receive the ressure of the chine and prevent the cor ofA the box from becoming broken which would weaken the box. Of course, these lateral portions 18` extend all around the inner corners of the box andv along the side Walls` cords cannot be cut or weakened and, therefore, the box will maintain its original strength. Also is it important that the stri s be on the inside of the box because when t e box is pulled across the ioor or counter, the strips will not b e torn oi as they are protected by the box proper.'

It will, therefore, be seen that a. box con-v structed in accordance with my invention can be easily made and reinforced in an efficient manner.

What I claim and desire to secure by Letters-Patent is:

In a corrugated board box, Ia joint formed by first producing a narrow compressed zone in a corrugated blank, then reinforcin said zone by pasting thereon a thin stri o ilexible material wider than the widt of said zone. f.

In testimony whereof I affix my signature.
