A ttorney Patented Feb. 13, 1934 e dFFiQE 1 Claim.

The object of this invention is to provide a tobacco box made of celluloid or other equivalent material in which the celluloid may or may not be transparent and if it is transparent the contents of the box will of course be visible. The box may be used for holding tobacco in any form such as smoking tobacco for a pipe or for cigars or cigarettes.

Another object of this invention is to provide the box with a sliding top which holds the tobacco in, which top is adapted to normally hold itself in closed position and which can be wholly or partially removed when the box is being filled.

Another object or the invention is to make the body of the box of a tube which can be formed of a single sheet of celluloid with overlapping or butt edges, or the tube can be made of a long thin sheet of celluloid which is wound upon itself in several layers, the various layers being formed into one single layer by heating or otherwise as is customary in making material of this sort.

It is also understood that the tube may first be formed oval of the finished shape desired, or it may be formed round and later changed to an oval or flattened piece as may be desired.

These and other objects of the invention will be illustrated in the drawing, described in the specification and pointed out in the claim at the end thereof.

In the drawing:

Figure l is a side elevation of the box.

Figure 2 is an end elevation of the box shown in Fig. 1.

Figure 3 is an end elevation of the cover.

Figure l is a side elevation of the box with the cover partly removed.

Figure 5 is a top plan view of the box with the cover partly removed as shown in Figure 4.

Figure 6 is a bottom plan view of the cover shown in Figure 3.

Figure 7 is a sectional view of the box in the process of being wound up in several layers from a long sheet or" celluloid.

In the drawing like reference numeral indicates like parts.

In the drawing reference numeral 1 indicates the box having parallel sides 2 and 3 and having oval ends l and 5, although it will be understood that these ends may be made with square corners if desired or with a flattened curve on each end if so desired, or with flat ends connected with curves of short radius.

The bottom of the box is closed by a bottom 6 as is indicated in Figure 4 which is preferably made integral with the box by being cemented or being fused or heated to the sides of the box.

The top or upper edge of the box is made with the grooves or guides 7 and 8 formed therein which grooves are formed by drawing the material down from above. These grooves stop short of the ends of the box which leaves the box with the ends 9 and 10 slightly raised and out of line with the sides of the box. This is useful for keeping the cover of the box firmly in place thereon as will presently be described.

The top of the box is made of a single sheet of celluloid 11 with overhanging flanges 12 and 13 thereon which engage in the grooves or guides 7 and 8. The upper surface of this top is made substantially fiat and when the top is in central position as is shown in Figure 1, the ends of the cover will be slightly sprung up by the raised ends 9 and 10 of the box, and this serves to hold the cover firmly in place so that the box will not be accidentally opened at either end enough to permit the loss or spilling of tobacco therefrom. It will also be understood that the flanges 12 and 13 do not extend the full length of the cover as is shown in Figure 1. This leaves the ends of the cover without any stiffening or reinforce so that they can spring to better advantage and adapt themselves to the raised ends of the box.

Centrally of the cover on the under side thereof is placed a disc 14 which acts as a shoulder and engages either end of the box as the cover is moved one way or the other thereon. This permits the cover to be opened to the extent shown in Figure 5 by moving it in either direction. The cover can be completely removed from the box by springing up one end thereof far enough to lift the disc 14 over the rim of the end of the box after which the cover can be completely removed. The material of the cover is flexible enough to permit this to be done.

In Figure '7 I have shown a diagrammatic view of the box in the process of being formed by being wrapped up from a long thin strip of celluloid. The strip is long enough to wrap two or more layers into the tube and thick enough to give the finished box the desired thickness. This celluloid is then heated until the several layers congeal together, or the layers may be cemented together and heated thereafter to make it conform to the desired shape.

As indicated at in Figures 4 and 5 I can use a brace of celluloid to hold the sides at a predetermined distance apart so that the sides cannot be permanently bent toward each other,

to engage the grooves in the sides, the ends of the cover being sprung up by the raised ends of the box and the intermediate part of the box being sprung down by the engagement of the flanges with the grooves in the sides of the box, said cover having a projection on the under side thereof adapted to engage with the ends of the box and limit the travel of the cover.
