Patented Dec. 25, 1945 CONTAINER Hans A. Eggerss, Van Wert, Ohio, assignor to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application August 12, 1937, Serial No. 158,768 j 3 Claims.

My invention relates to containers. It has to do, more particularly, with a barrel or container that is formed primarily of such material as fibre board, pulp board, paper or strawboard, although it is not necessarily limited thereto.

One of the objects of my invention is to provide a container or barrel of the type indicated which is composed mainly of fibre board or other similar material but which has a metal head applied to the end thereof in order to make the container useful for packing a wide variety of commodities and in order to produce a container of very sturdy construction.

Another object of my invention is to provide a. container or barrel of the type indicated having a metal head of such a type applied thereto in such a manner that the container will be effec tively sealed.

Another object of my invention is to provide means for eiliciently securing the head on the container in such a manner that there willbe no danger of the head accidentally slipping off the container regardless of the forces to which the container is subjected.

Another object of my invention is to provide a metal barrel head which is of such a nature and which is applied to. the fibre body portion of the container in such a manner that a chime will be produced at the end of the container which will effectively withstand all shocks to which the container might be subjected.

Another object of my invention is to provide a barrel head and means for securing it in position on a container of the type indicated of such a nature that the headmay be quickly'and efficiently applied to the container or may be quickly and easily removed from the container.

In its preferred form my invention contemplates the provision of a container comprising a substantially cylindrical body portion which is made of fibre board or other similar material and which has an open end. The extreme end of the fibre body portion is embraced by a metal band which is firmly secured thereto. A metal head is applied to the end of the body portion and is provided with a portion formed at its edge which is adapted to fit over and embrace the edge of the body portion of the container and the metal band carried thereby. The metal head frictionally engages the metal band secured to the body portion so that it will tend to stay in position on the container. However, in order to firmly hold the metal head in position on the container I provide a split metal ring or hoop which is adapted to be drawn tightly around the extreme end of the container and this ring or hoop is provided with a portion on its lower end that fits into a groove formed by bending the end of the body portion and the cooperating metal band. This portion prevents the split ring or hoop and, consequently, the metal head from slipping outwardly off the end of the container. Means is also provided for firmly holding the split ring or hoop in contracted condition.

The preferred embodiment of my invention is illustrated in the accompanying drawing wherein similar characters of reference designate corresponding parts and wherein:

Figure 1 is a DBISDBCtiVfiliViBW showing one end of a container having a metal head applied thereto in accordance with my invention.

Figure 2 is a vertical section through a portion of the container illustrated in Figure 1 showing how the metal head is secured in position.

Figure 3 is a view partly in perspective and partly in section illustrating mainly the means for holding the split ring or hoop in contracted condition on the container.

Figure 4 is a similar view illustrating a slightly modified form of my invention.

With reference to the drawing and particularly to Figures 1, 2 and 3, I have illustrated a container comprising a body portion I This body portion may be made of fibre board or other similar material. It is mainly of cylindrical form and has an open end.

The end of the body portion of the container is adapted to be closed by a metal head 2. The opposite end of the container-may be closed by other suitable means, or if desired, a metal head 2 may be applied to both ends.

In order to reinforce the end of the container and to provide means for securing the metal head in position, a metal band 3 is preferably applied to the end of the container. The metal band 3 is preferably a continuous annular band and is preferably comparatively wide. It is applied in surrounding relation to the outer surface of the container and its upper edge is curled inwardly as at 4 over the extreme edge of the container. The extreme upper edge of the metal band is bent inwardly until it is forced into the inner surface of the fibre body portion as indicated at 5. After the metal band 3 is applied to the body portion, both the band and the body portion are bent simultaneously to form an external continuous groove 6 and an inwardly projecting rib or shoulder 7. Thus, it will be apparent that the metal band 3 will reinforce the end of the fibre body portion. Furthermore, the band is applied to the body portion in such a manner that there will be no danger of its slipping from the body portion.

The metal head 2 comprises a central disk-like portion 8. At the edge of this portion a downwardly and outwardly inclined portion 9 is formed. A vertical portion Illextends upwardly from the lower end 01' the portion 8. This portion I is adapted to lie closely adjacent the inner surface of the rib or shoulder I and to form a seal at this point. The portion III is connected to a substantially inverted U-shaped portion II by means of a horizontal portion I2. The extreme edge of the portion II is curled as at I3 for reinforcing. The head 2 is made of metal which is pressed into the shape shown and just described forming a head with integral means for cooperating with the container to secure it in position. It will be apparent that the portions I0 and I2 will cooperate with the internal rib or shoulder I while portion of the metal band 3 and will frictionally engage the metal band. Thus, there will be a tendency for the metal head to be frictionally held in position.

In order to prevent accidental slipping of the head oil the container, I provide a split contractible ring or hoop Il. Adjacent each oi. its ends, this ring or hoop Il is provided with an aperture I5. These apertures I5 are adapted to receive lugs or loops I6 which are formed in the outer flange of the U-shaped portion II of the head 2. The hoop or ring Il is provided with an inwardly turned upper edge I! which cooperates with the correspondingly curved portion of the U-shaped portion II. Intermediate its top and bottom edges it is bent to form an external continuous groove and an internal rib as at I8. The inner surface of the portion I8 engages the outer flange of U-shaped portion I I of the head 2. The extreme lower edge of the ring or hoop Il is provided with a curved portion I! that contacts with the curled portion I3 of member 2. This extreme lower edge is also provided with a portion 23 that extends into the exterior groove 6. In applying the ring or hoop ll to the container, it is disposed on the container and the cooperating portion of the head in the manner illustrated in Figure 2. Then the ring Il is contracted until the apertures I5 thereof can be slipped over the lugs or loops it formed on the head 2. The apertures l5 and the portions I6 are so located that when they are closed in cooperative relationship with each other, the ring II will be contracted to such an extent that it will force the outer flange of the portion II of head 2 into ilrm contact with the adjacent portion of the band 3. Furthermore, the portion 23 will be 'forced into groove 6 in band 3. Thus. it will be apparent that when the split ring or hoop is contracted, there will be no danger of the head slipping from the container, due mainly to cooperation of portion 23 with groove 8 which will prevent outward movement of the split ring Il. To remove the head from the container, it will be necessary to force the ends of the ring I l outwardly until the lugs I6 are completely removed from the apertures I5.

It will be apparent that when the lugs or loops ll project through the apertures IS a wire may be threaded through the opening in the lugs or loops, as indicated in Figure 3, and the ends of the wire may be fastened together either by a metal seal 2| or other suitable means. The wire 20 will prevent the ends of the ring or hoop Il from being forced outwardly accidentally thereby causing the lugs Il to be withdrawn from the apertures I! and permitting the ring Il to expand which, in turn, would permit the head 2 to slip oi! the end of the container. The portions I1 and Il of the ring I l will prevent downward movement of the ring while the portion 23 will cooperate with the groove l, iormed in the band 2 and cooperating wall of the container, to prevent upward movement thereof. The portion 23 of ring ll will contact with the band I at the point indicated by numeral 2l.

At the time the head 2 is applied to the container, the metal band 3 will be in position on the container and will be firmly secured thereon. To seal the container so that it will be sub-' stantially fluid-tight, a disk 22 of paper may be provided with its edge disposed between the cooperating portions of the container and head, as indicated best in Figure 2. When the head is positioned on the container, the portion III will firmly contact with the internal rib I and will provide an effective seal at this point. The portion I2 will rest on the upper portion of shoulder I and the top of the inverted U-shaped portion I I will rest on the top edge of the band 3, preventing further inward movement of the head. The ring Il will be contracted and maintained in contracted condition and will, consequently, hold the head firmly in position on the container. It will be noted that the flat disk-like portion 8 of the head 2 is disposed at a slightly higher level than the extreme upper end of the chime of the container. This will serve to protect the chime from blows. Any inward force applied to the portion 8 of the head will tend to force the lower end of the portion 9 outwardly and,

consequently, force the portion ID of the head more tightly into contact with the internal rib or shoulder I and, thus, will produce a better seal. Any blows that are applied to the chime of the container will cause the walls of the groove 8 to be forced towards each other and, consequently, will force the rib or shoulder I farther inwardly. Thus, this will enhance the seal between the portion III of the head and the shoulder 1. Forces applied to the hat portion 8 or to the chime, consequently, merely enhance the sealing effect between the portion III of the head and the internal rib or shoulder I.

In Figure 4 I have illustrated a slightly modified form of my invention. All parts of the structure are exactly the same with the exception of the ring Ila corresponding to rin Il. In this instance, however, the extreme lower edge of the ring Ila is turned inwardly and then outwardly to form a portion 23a that fits within the exterior continuous groove 6 formed in the band 3. This portion 23a will serve to prevent both inward and outward movement of the ring Ila relative to the container. Furthermore, since the portion 23a projects into the groove 6, the rin Ila will also cooperate with the metal band 3 to prevent upward movement of the metal head relative to the container. The portion 23a will contact with the metal band at the point indicated at 2la to prevent such movement of the metal head relative to the container. The portion 23a also forms an external continuous groove 25 which is adapted to receive a wire ring 28 that may be contracted around the ring Ila. The wire ring 26 will aid in preventing the ring Ila from being forced off the cooperating portion of the metal head.

It will be apparent from the above description that I have provided a container which is composed mainly of fibre board or similar material but which may have one or both ends closed by a metal head which will make the container useful for packing a wide variety of commodities and will produce a container of very sturdy construction. The head is applied to the container in such a manner as to effectively seal the container. Furthermore, the means for holding the head on the container is of such a nature that there will be no danger of the head accidentally slipping off the container regardless of .the force to which the container is subjected. The metal band permanently secured to the end of the container and the portion of the metal head which extends around the end of the body portionwill effectively reinforce and protect the end of the body portion. Furthermore, the means for securing the metal head in position on the body portion of the container is of such a nature that the head may be quickly and efficiently applied to the container or may be quickly and easily removed from the container.

Many other objects and advantages will be apparent from the preceding description, the drawing and the following claims.
