This invention relates to a container, more particularly to a bung ring and its mounting in one wall of a container.

One object of the invention is to provide a con- 5 tainer having in one of its walls an improved bung ring and a mounting therefor, these parts having interlocking elements adapted to fixedly connect the bung ring in the container wall.

Another object of the invention is to provide a container having in one of its walls an improved bung ring and mounting therefor in which provision is made to lock the bung ring to the container wall and also clamp it thereto to insure a liquid tight seal.

A further object of the invention is to provide an improved bung ring and mounting therefor which are relatively simple in construction, may

be made economically and permit of ready as-.

sembly.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings, wherein Fig. 1 is a fragmentary plan view of a container I having in one of its heads a bung ring and a mounting therefor embodying my invention. Fig. 2 is a section on the line 2--2 of Fig. 1. Fig. 3 is a fragmentary plan view of the con- 30 tainer wall having an opening, the peripheral edge ofthe opening and the metal of the wall around the opening being shaped and constructed to receive my improved bung ring.

Fig. 22 is a section on the line 22-22 of Fig. 21.

Figs. 23 and 24 are side bottomplan views, respectively, of the bung ring shown in Figs. 19 and 20.

In the drawings, l indicates as an entirety a container, such as a steel drum or barrel having' a cylindrical body la and heads therefor at its opposite ends, only one head lb being shown, since in the preferred construction the bung 20 ring is mounted in one head. Preferably the body and each head is united by a double seam 2,

3 indicates as an entirety a bung ring, a portion of which extends through an opening 4 formed in the head lb, the bung ring 3 com- 25 prising a body or neck portion 3a which extends through the opening 4 and a flange 3b which rests on the marginal portion of the head or wall lb surrounding the opening 4. The bung ring 3 is internally threaded, as shown at 3c for a threaded plug or other device (not shown). Means are provided for interlocking the bung ring body 3a and walls of the container or the metal forming the periphery of the opening 4 or marginal portions of the walls surrounding the opening; I also provide separate means which co-operate with the flange 3b and engage the body 3a. to clamp the flange 3b to the head lb.

Referring to Figs. 1 to 8, inclusive, which illustrate one embodiment of the invention, the (,0 metal of the wall or head lb is distended (preferably downwardly) as shown at 5 and extended horizontally as shown at 6 to form a pocket or seat for the flange 3b. The means for interlocking the body 3a and walls of the container to prevent turning of the bung ring comprise a plurality of longitudinally extending ribs 1 disposed in spaced relation and provided on the outer side of the body 3a and complementary recesses 8 formed in the horizontal wall 6 and constituting cut-aways in the periphery of the opening 4. As most clearly shown in Figs. 5 and 6, each rib 'l is shaped to provide outer and. side walls disposed preferably at right angles to each other. The clamping means comprises bung ring 3 in fixed relation.

a ring 9 and a securing means'therefor. The in-' ner wall 9a of the ring is complementary to the outer wall of the body 3a, so as to fit over the lower end of the latter against the lower face of the wall 6, the recesses or cut-aways. 9b of the opening 9a serving to interlock the ring 9 and The securing means'for the ring 9 is provided by riveting the lower ends of the ribs 1 over and upon the ring 9, as shown at l0. In carrying out the riveting operation, the bung ring 3 is rigidly held so that the ring 9 will be forcibly clamped toward the flange 3b, to secure the flange to the wall 6, thereby forming an effective seal. When desired a suitable gasket H may be provided between the flange 3b and wall 8.

Referring to Figs. 9, 10, 11, 12, 13, 14 and 15,

showing another embodiment of my invention,'

the interlocking elements between the bung ring indicated as an entirety-at 3' are reversed and the external wall of the bung ring body 31; is threaded, as shown at l2, for a purpose later to appear. In this construction, I (a) form in the external wall of the body 3a a plurality of recesses or cut-aways l3 extending from the free end of the body longitudinally toward and approximately to the flange 3b and (b) provide on the periphery of the opening 4' depending arms l4, one for each recess and fitting therein bung ring. The clamping means consist of a as shown inFigs. 9 and 10. The arms 14 are formed integralwith the horizontal wall 6", on which the-flange 3b rests, and have a width substantially equal to the width, of the recesses l3,

so that when the bung ring is positioned in the opening 4' with its flange 3b in its seat, the arms l4 and side walls 'of the recesses I3 will be interlocked to prevent rotative movement of the ring I5 internally threaded and adapted to engage the threads l2 and when screwed thereon j and tightened against the wall 6, as shown in the wall 6' will be clamped betweenthe flange 3b and ring l5. Theiouter wall of the ring I! is formed with notches I6, whereby a suitable tool may engage the ring to turn it.

Referring to Figs. 16,- 17 and 18, inclusive, I show an embodiment of my invention substantially similar to that shown in Figs. 9 to 15, except that (a) the body 3a of the bung ring 31: is provided on its exterior with tapered threads IM and the ring l5a is provided interiorly with a tapered threaded wall adapted to engagethe threads l2a (as shown in Fig. 16); (b) the inner or bottom walls of the recesses [3a are parallel to the tapered threaded wall l2a; and (c) the depending interlocking arms I40, are inclined at the same angle so as tolie flat against the bottom walls of the recesses I 3a. In this form of construction, the depth of the recesses I31: and thickness of the arms Ha may be relatively proportioned so that when the ring l5a is screwed into clamping relation (Fig.' 16), its inner wall will engage the arms la and clamp them against the bottom of the recesses.

While I have shown a gasket between the bung ring flange and the adjacent wall, the gasketmay be positioned between this wall and the clamping ring; or if desired gaskets may be, in-

terposed between this wall and the flange and ring.

Referring to Figs. 19 to 24, inclusive, I show an embodiment of my invention substantially similar to that shown in Figs. 1 and 2, except that r omit the clamping ring 9. In this form of construction the body I! of the ring 3" fits into the opening 4 of the container wall lb and the ribs 1 on the exterior wall of the body flt into the cut-aways 8, whereby the bung ring is interlocked with the horizontal wall 6 and the lower ends of the ribs are riveted over or upon such wall as shown at Hl', thereby clamping the flange 3b of the, vbung ring thereto. The interposed gasket H which has a width substantially equal to the width of the wall 6 and engages therewith throughout its circumference outside or beyond the cut-aways 8, serves to insure a liquid tight sealbetween the flange 3b and wall 611:.

It will be noted that in my forms of construction I provide interlocking means and clamping means which conjointly secure the bung ring in rigid position. It will also be noted that the interlocking. elements carried by the wall lb are formed in or carried by the bottom, horizontal wall forming a seat for the bung ring flange; but

tion relates many changes in construction and widely differing embodiments and applications of th invention will suggest themselves without departing from the spirit and scope thereof. My disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting. No claim is made herein to the embodiments of the invention shown in Figs. 9 to 18, inclusive, as the same forms the subjectmatter .of a divisional application Serial No. 5,651 filed by me on the 8th day of February. 1935.
