of piles of paper with a layer of reenforcing wire fabric associated therewith. Various other-detail features vand advantages of the invention will be apparent from the following disclosure, when read in connection with the accompanying drawing, in which:;

Figure 1 is a side elevation of a nail keg embodying the invention; a

Figure 2 is a plan thereof; Figure 3 is an enlarged vertical section on line III-.111 of Figure 2; I

Figure 4 isa plan of Figure 3 with portions broken away in the interests of clarity; and

Figure 5 is a detail-horizontal section on line V'-V of Figure 3.

Referring in detail to the drawing, in the em- 2 bodiment of the invention illustrated the numeral ll represents generally the main body portion oi a cylindrical nail keg. This body portion comprises inner and outer plies i2 and ll of paper, cardboard or the like, between which there -is interposed a, reenforcement of wire fabric I. This reenforcemen't maybe in the nature of com-' mercially obtainable metallic screen cloth comof interengaging warp and weft strands woven together or otherwise interconnected.

5 The woven fabric is constructed of metal wire of very light gage, comparable to that used for ordinary window screening. It is bonded or intimately secured to the plies I 2 and Il by the use of a suitable adhesive, such as known types ofasphaltic, resinous or hydrocarbonaceous materials. The overall or multi-ply thickness of the wall II is of the order of approximately of an inch. With such thin material it is important to provide means to resist collawe, particularly at thetop and bottom, where the heads or end closures are secured. For this reason I deem it important to provide an end assembly which serves the double function of securing the head in place at the end of "the container and also reenforcing the same. Containers such as nail kegs and the like preferably are of inexpensive construction. To this end I have devised the improved end closure structure herein shown and claimed which is peculiarly well suited for. use in 66 combination with a container-whose main body is made of paper, cardboard, or similar thin light material possessed of relatively low inherent resistance to collapse.

. The improved end closure assembly may be used at both top and bottom r the container. Such end assemblies are indicated generally at .the baseby II and at thetop by 20. It is notessential, however, that the construction be the same at bothtop and bottom.

More specifically, the end assembly embodying characteristics of the present invention involves the use of an outer annular strap 22 and an inner closure or head receiving rim I4. The outer annular strap is a plain strap, the ends of Y which are overlapped, as indicatedin Figure 5, u and spot welded together, as indicated at 26. The ends of the inner closure rim 24 are similarly overlapped and spot welded together, as indicated at 28. The strap 22, the mainbody III and the rim-24 are firmly secured to one another-by suitable means, such as the staples 25, whose inner extremities are bent over or clinched, as clearly shown in Figure 5. I The inner rim 2! is provided intermediatev its ends with a pair-of opposed, inwardly extending flange portions II 32 united by the bent portions 34. The flange portion 32 forms an annular shoulder upon which is seated the closure or head it. This head is preferably, although not neces-" sarily, made of plywood or the'llke of mately V4 inch in thickness. a At the outer extremity of the rim 24 there is an outwardly extended portion 38 of substantially U-shape forming an annular seat 40 which coacts ,with aring 42 which, in combination with the 35 outer annular strap 22,, the inner head receiving rim 24 and the head ll serves the double function of a reenforcement and locking means for releasably holding the head I. firmly seated on the annular shoulder". In order that the ring 40 shall contribute to this dolible function, it is important that it possess two main characteristics; first, it shall beof a thickness materially greater than that of the thin sheet metal radially. The ring is preferablymadeoi' iron or steel and possesses a certain amount of inherent resiliency. Such a ring, which in cooperation with other parts, performs the double func- '86 approxi I of which-the strap .22 and the rim 24 are'co 4 opposed tongues.

- also functions to protect the fabric of the keg tion within the annular seat 40. The inner surface of thering is substantially flat, as indicated at 52, and the outer face of the ring is convex, as indicated at 54. This sectional contour provides a flat seating surface for effective coaction with the flat upper surface of the head 36, and the rounded outer surface provides sufficient taper to facilitate engagement and disengagement, with the grooved seat 40.

The relationship of the overlapping tongues 48 and 50 and their relation to the notched portions of the ring provide a readily detachable split joint. Once the parts are assembled the keg can be readily opened merely by the insertion of a suitable prying tool in the space 58 between the Uponprying the tongues apart the inherent resiliency of the locking ring 42 will cause one end of the ring to spring inwardly and I thus facilitate the prying out of the remaining portion of the ring,,it being understood that the remaining portion will be wedgingly engaged with the annular seat or groove 40 of the rim 24.

In the described construction it will be apparent that when the locking ring 42 is in its normal operative position, illustrated in Figures 3 and 4, due to the curved upper surface thereof, its pewill wedgingly engage the outerripheral portion flange of the U-shaped seat 40. Because of the interlocking of the ends of the ring' and the engagement of the ring as a whole with the annular seat 40 and the fact that the ring is of relatively thick metal as compared to the thickness of the strap 22 and the rim 24, it. will be apparent that the ring 42 serves to retain the head 36 in position,

and also to stiffen and rigidify the entire end closure assembly. This is desirable as all other parts, with the exception of the plywood head, are made of very thin sheet material of relatively low inherent strength and It is deemed preferlow resistance to collapse. able, in order that the ring maycooperate with the other parts to serve the double function, that it be of a cross sectional contour other than circular. This is because a ring of circular cross section of sufficient strength to adequately r6- sist collapse would be so large that an outer portion 38 of undesirable size would be requiredand such an enlarged round ring would not have the desirable flat surface to properly seat against the flat face of the head. The relatively wide, flat, thick ring of the contour shown and described therefore meets the essential requirements in a manner in which they would not be met by a ring of circular cross section. The outwardly extended portion of the rim 3! which forms theannular seat for receiving the ring 42 when the same is rolled on the floor, it being apparent from the of. the rim is sufficient away from the floor when the on the annularrim 3|. 1
