ferred to herein as a drum container, the inhit vention is concerned with a container essentially round in cross section, while it may be cylindrical or conical. The invention is concerned particularly with the end head construction of such a container and the manner in which it is associated with the body of the drum container. Among the objects of the invention is the provision of an end head construction for drum containers, which is so constructed that it can be secured to the drum as by means of stitches or rivets, or thread or wire sewing, and yet provide a substantially leak-proof container. At the same time, the construction is such as to form a material reinforcement for the end edges of the drum, which is particularly advantageous with large containers, which vary probabl in their handling, will be rolled on their end edges, also stacked on end, and conveyed in upright position on conveying trucks.

In the accompanying drawing:

The body of the container, as illustrated in 1929. Serial No. 366,795.

Fig. 1, is cylindrical and it is composed of a wall 1. The body of the container may be made up in a number of different ways; for

example, a single piece of fiber board material may be shaped into cylindrical form with its opposite marginal portions overlapping. The marginal portions may be secured together as by means of the rivets, or wire stitches 2. This forms a vertical seam in the cylinder. The vertical seam may be constructed, as illustrated in Fig. 3, wherein the marginal edges of the cylindrical wall are brought into substantial abutting relation, and a securing strip is provided, which bridges the abutting edges and which is stitched, or riveted to each by means of devices 4. The bridging strip 3 may be placed either inside or outside of the container. and as shown in Fig. 3, it is in the inside. There are at present available, winding machines which provide cylindrical containers by helically wound fibrous material, and the drum or cylinder may be made up in this manner it desirable.

One or both ends of this cylindrical container may be closed by the head now to be described. This end head comprises essentially what may be termed an end head ring 10. This ring is of channel formation, or U- shaped in cross section. The U is inverted in the case of the top end of the cylinder. The marginal edges of the cylinder are fitted into the U formation so that one leg of the U, as illustrated at 11, fits around the outside marginal edge of the cylinder, while the other leg 12 fits within the marginal edge of the cylinder. The bight portion 14 is designed to be urged down in contact with the edges of the container wall in a manner later to be described, so as to form a very tight closure. This end head ring is provided with an inwardly extending flange portion 15, for the purpose of supporting the body of the end head. As shown in Fig. 1, the end head proper is composed of two discs of suitable iiber board or the like 16 and 17. The disk 17 is of a size, preferably. as to snugly fit into the cylindrical container. while the disc 16 is slightly smaller so as to fit within the portions 12 of the end head ring.

With this construction, the discs 16 and 17 may be secured, and preferably are secured, to the flange 15, as by means of suitable wire stitches or rivets 18, while the end head is held in place to the body of the container, as by means of suitable wire stitches or rivets 19, which extend through the legs of the U and marginal portion of the cylinder. It is, of course, feasible to secure the said parts together by means of sewing with thread or wire, or in some instances, where it is desirable, glue could be used.

The end head ring can be constructed in different ways. For example, it may be stamped out of a sheet of suitable material, and formed into shape by dies or the like, but it is preferable to form it from a strip of suitable fiber board material or metal. lln this event, an appropriate length of material is required, and preferably, it is first shaped into the proper cross sectional shape and then bent or spun into circular shape, with its ends overlapping, as illustrated in Fig. 7. The overlapping ends may be secured together as by means of one or more stitches or rivets 20. A problem is presented herein, of the differential between the inner and outer diameters of the flange 15 when the end head ring is made from a strip of material as just described. It is thought to be preferable to form the end head ring by distorting the material in the flange 15; by this is meant that the material may be compressed somewhat near its inner diameter. This may be expedited by softening the flange by means of steam or water treatment. The end head ring can be provided, however, by cutting the same radially, as at 21 (Fig. 6) to permit of slight overlapping of the material adjacent the slots when the same is formed into ring shape. Satisfactory results have been obtained by making the end head ring without the radial slots, and this is preferred.

Varying requirements of a container of this nature are such that different types of heads may be employed in containers. designed for different usages. For example, in Fig. 4 the end head of the container is shown as consisting of merely one disc 1666, which is placed on the outside of the flange 15 of the end head ring. In Fig. 5 the end head consists of a single disc 17a, which is placed on the inside of the flange.

There are a number of advantages to this head formation. One is that a sift-proof end head is provided for a container of the type described. This is accomplished by reason of the fact that disc 17 relatively tightly fits into the drum and also due to the fact that in securing the end head to the drum the same is urged against the drum until the edges thereof tightly abut against the bight portion 14 of the U formation of the end head ring. Thus a double seal is provided. Of course. where the seal need not be so secure, an end neeaees head construction such as shown in Fig. 4: may be used. However, a very satisfactory seal is provided by the end of the container abutting into the bight portion of the U of the ring. The end head construction, as shown in Fig. 5 provides for the double seal, yet does not afford the strength of the double head as in Fig. 1. Another advantage is that the head is uniformly positioned, so that a multiplicity of containers of this character are exactly uniform. In other words, the end head of each container is exactly positioned by the end edges thereof abutting against the bight portion of the U. This not only adds to the appearance of the containers, but facilitates handling and stacking of the same.

Preferably, the material used for making the end head ring, is such that has a relatively high resistance to wear, or in other words, of relatively tough fibrous material especially in containers of large size. This is done because containers of this nature are usually stacked on end, and when moved from place to place, are often rolled on edge. Also the end head ring can in some instances, be made of metal where this is desired.

Claims:

1. A fiber board container comprising, a drum-shaped body, an end head ring having a U-shaped formation in cross section and separate from the body, said end head ring being placed onto the end of the body with the bight portion of the U abutting against the edge of the drum body and with the legs of the U lapping the inner and outer sides of the wall of the drum body, a plurality of metallic stitches circumferentially arranged and in spaced relation extending through the legs of the U and marginal portions of the drum wall for securing the end head ring to the drum body, an inwardly projecting flange carried by the end head ring, and a fiber disc-like end head closure member overlapping said flange and metallic stitches securing the same thereto.
