. 40mm; (cl; 217-12) The present invention relates to improvements in box material, and its principal object is to provide a new material for making boxes that combines the advantages of the wooden box with those of the conventional paper box, and in some ways is superior to both. i s

-More particularly it is the object of the present invention to provide a box material in which com paratively thin slats of'wood are glued to a paper backing to impart stiffness to the latter and in which the box material thus prepared is grooved to allow the same to be folded into'box form. When the box is formed, the slats are disposed on the inside of the box and the paper on'the outside. The narrow sides of the slats abut each other, and in the eventof their being cross sectionally rectangular, said narrow sides extend This wall will bend more under pressure than will the truss wall. The truss wall is thinner than the wood used in the conventional wooden box, for equivalent purposes, and therefore takes up less space for specified inner dimensions. It is airtight and water-resisting like awooden box, while on the other hand it may be folded like paper, and the edges of the box may be formed without the use of nails.

In making the new box material I use preferably waste wood whereby the cost of the box is reduced considerably.

Further objects and advantages of my inven tion will appear as the specification proceeds.

The preferred formof my invention is illustrated in the accompanying drawing, in which Figure 1 shows in perspective view a sheet of box material made in accordance with my invention;

Figure 2 is a perspective view of the shell of a box made out of my box material; and

Figure 3 an end view of a portion of the box material shown in Figure 1.

While I have shown only the preferred form of my invention, I wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached tion. I r 'In'its preferred form my invention comprises without departing to bear acertain relationto the paper backing which allows the-latter to serve as a weight carrie'r' for the wooden slats. The slats are prefer- {ably fed automatically by"machine r and are made rectangular in cross section and of even thickness so as to present a smooth top surface. They are laid in adjacent relation so that a complete and continuous layer of wood is presented. After a sheetof box ma erial has been prepared from thespirit of the invenin this manner a plurality of grooves 3 are cut spaced to correspond to the size of box desiredand the grooves being preferably madein V-shape so as to define a right angle. The grooves are also cut to the full depth of the slats so that no wood material remains in the bottom of the groove. For the purposes of my invention it is not necessarythat the grooves coincide with any of the joints between any two adjacent slats and as a matter of fact it is not essential that the grooves be cut parallel to the slats. If desired the grooves may be arranged at right angles to the slats, or at any other angle according to the results desired.

To make a box, such as shown in Figure 2, out of the sheet of box material prepared as shown in Figure 1, it is merely necessary to bend the box wood at the grooves to form right angles, the paper serving as a hinge. The two end pieces are preferably made of sufficient length that when the box is formed the extremity of one end will lie over the edge of the other end as shown at 4, and these two ends may be permanently secured together by means of nails 5. After the box wood has thus been formed into a box-like shell end pieces may be applied in any suitable manner as indicated at 6 to complete the box.

It will be noted that a box made in accordance with this method has the advantages of the wooden box insofar as it forms a complete layer of wood around the contents of the box, while on the other hand it has the advantages of the paper box because it is cheaply manufactured and light in weight. It has the advantage over a paper box into the assembled product, the grooves being My box material is particularly adapted for cigar boxes and for shipping all kinds of merchandise, canned goods that are usually shipped in either wooden or paper boxes. t is only slightly heavier than a paper box and is preferably about forty per cent less in weight than a wooden box made for the same; purpose. -The* sides of a wooden box of the same thickness as the truss wall will bend more readily under pressure than the truss wall. .Due to the fact that the material is thinner than wood employed for the same purpose, the boxtakes up less room and thus saves in shipping space.

1. A folding box havin truss walls formed from a continuous layer of paper and each wall consisting of a continuous layer of slats cemented to the-paper, the slats being disposed on the inner surface of the paper and having their narrow sides abutting each other,;the narrow sides extending at right angles to the plane of the paper to give a truss, effect to the wall when outward pressure is applied against the slats, said slats having V-shaped cuts forming mitered corners for the folded box, the slats forming the sides of the corner having an equal and full bearing against each other at the miter joint, and holding the sides at right angles to the bottom, and end pieces for the box, the layer of paper forming a complete and continuous band around the box.

2. A box formed with top, bottom and side walls having a layer of paper on the outside and each of said walls consisting of a continuous layer of slats secured to the inside of the paper, the slats having narrow sides abutting each other and extending at right angles to the plane of the paper, whereby the paper forms a truss against outward pressure from the contents of the box,

and end pieces for the box.

3. A truss-like material for boxes comprising a layer of paper and a continuous layer of slats glued to the paper and having their narrow sides abutting each other and extending at right angles to the plane of the paper, the slats being so proportioned and arranged that each wall when formed will contain a plurality of slats, said slats cooperating with the paper for acting as a truss to prevent the bending of the wall from pressure against the slats.

4. A box comprising walls consisting of a continuous layer of paper which forms the outside of the box, and each wall consisting of a continuous layer of slats forming the inside of the box, said slats having one flat side cemented to the paper and the narrow sides in tight abutment, those edges of the slats farthest from the paper constituting the fulcrum of a truss the base of which is composed of the paper covering the adjacent edges of the slats, said truss preventing material outward bowing of the walls.
