9 Claims.

This invention relates to a container having at least one wall that is formed of sheety metal of any desired gauge; more particularly the in-` vention relates to a bung ring and its mounting in the sheet metal wall of a container.

As illustrating one application of my invention, I have shown a container having its side walls and heads made of' sheet metal stock.

One object of the invention is to provide an improved process of mounting a bung ring in a sheet metal wall.

Another object of the invention is to provide an improved container having a mounting for a bung ring, whereby the latter may be rigidly secured in position.

Another object of the invention is to provide an improved bung ring and mounting therefor,

so constructed and arranged that the bung ring may be readily positioned in its mounting and secured against turning and dislocation.

A further object of the invention is to mount a bung ring in a container wall in a ready and economical manner and Without resorting to welding.

A further object of the invention is to provide a combined bung ring mounting and sealing v means therefor so related that the sealing de vice may be readily applied. I 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-y drawing, wherein Fig. 1 is a fragmentary section of a container showing a bung ring and its mounting, embodying my invention, incorporated in the containe head.

Fig. 2 is a plan view of the parts shown in Fig. l.

Fig. 3 is a section through the head on the line 3-3 of Fig. 2 and illustrating the first step of my process and the construction of the head ready to receivev a bung ring.

Fig. 4 is a section through the bung ring on the line 3-3 of Fig. 2.

Fig. 5 is a plan view of the bung ring.

Fig. 6 is a section on the lineL6-6 of Fig. 2.

Fig. 'i is a plan view similar to Fig. 2, but illustrating a slightly different form of construction embodying my invention.

Fig. 8 is a plan View showing the application of a sealing means'.

Fig. 9 is a section on the line 9-9 of Fig. 8.

In the drawing, 1 indicates as an entirety a container having side walls and heads, portions thereof being indicated at 2, 3, respectively, and suitably connected, as by a double seam 4. 5 indica'tes as an entirety a bung ring having a body portion 6 that is threaded internally to receive aplug 'I or other threaded device. The body poro tion is provided at its outer end with a flange 8 and at spaced. points circumferentially (preferably at uniform distances) the latter is provided with radial extensions or Wings 9, the purpose of which will later appear. These wings are in the plane of the flange 8 and lie flat in face to face lrelation to the head 3, except that certain of their free ends may be bent upwardly as will hereinafter appear. At its inner end, the

body portion 6 is provided with a relatively thin 7 tend/the metal of the headin the opposite dlso rection, that is, upwardly, as shown at 13, to provide a plurality of pairs of opposed abutments 13', the vinner side walls of which co-operate to form an annularbeat 14. The foregoing steps may be performed separately or otherwise by suitable u tools. 'Ihe distended portions 4,are disposed concentrically to the opening formed by the neck. 'Iheir inner side walls are spaced from the neck 12 a distance substantially equal to the width of the flange 8 to form-the seat 14 and their opposed 9 end walls form the abutments 13.- Next, a bung 5 of the construction above described is positioned in the neck 12. When the bung is thus positioned,` the seat 14 receives the annular flange 8, whereas each extension 9 lits between a. pair of abut- 95 ments 13', as shown in Figs. 1 and 2. Next, the

abutments 13' are up-set or bent over and upon the extensions as shown at 15 and the annular portion 10 is 11p-set or riveted over the free circumferential edge of the neck 12, as shown in Fig. 1'.

In my construction, the :up-set abutments and up-set portion 10 co-operate to secure the bung ring to the wall 3 and in its seat 14, whereas the abutments also prevent 'rotative movement of the 105 bung ring. As the walls of those portions of the metal, that are distended to provide each abutment, are integral with the head, each abutment is reinforced to resist any force acting on the bung ring to. rotate vit in its seat. i

each distended portion extends fromV one abuto ment of one pair to the adjacent abutment of the adioining pair so that the opposite end walls of the distended portion form the abutments just re,- ferred to. 'This construction insures the ready positioning of a bung ring in the neck 12 and seat 14. f

In the form of construction shown in Fig. '1, the distended portions 13 are shorter in length measured between two abutments 'and may be n proportioned to provide twice as vmany pairs of abutments as that shown in Fig. 2. When the headis constructed as shown, the positioning of the bung ring is greatly facilitated.

My construction is 'advantageous since the bung ring is sealed at both ends to the sheet metal wall of the container and in addition thereto it is i interlock'ed at uniformly spaced points with such wall by abutments disposed at right angles. to

portions or extensions of the bung flange and in the plane thereof. As the abutments are reinforced, danger of the bung ring turning is entirely eliminated. This result is more readily attained without putting undue strain on the distended portions 13 by reason of the fact that the or tampered with without breaking the seal or' interlocking elements are at remote points from the axis of the bung ring.

When desired a gasket 16 (of .paper or other material) maybe interposed between the ange 8 and metal of the head; and if desired the metal may be offset, as shown at 1'7 to receive the gasket.

18 indicates as an entirety a sealing means for the plug "I, whereby the latter cannot be removed otherwise indicating such tampering. The seal- Ving means comprises a member 19 having wings member 19 preferably comprises an inverted cup which encloses the head ,or top of the plug '1. One wing 201s enlarged and transversely slotted, as shown at 24, to receive thefree -end of the adjacent extension 9, which end is bent upwardly and the free end of the wing is bent downwardly Ato permit these parts to be interlocked, as shown in Figs. 8 and 9. The other, diametrically arranged wing is formed withan opening -25 which registers with the opening 23 in the adjacent-extension when the member 19 is positioned in the manner described, whereby the wire 21 may be passed through the openings 23, 25 and its ends sealed with the. slug 22. u

'Ihe free ends of the extensions may be bent upwardly, as shown in Fig. 8, or they may be positioned flat against the head 3, and two of them bent upwardly with a suitable tool when the seal is to be applied.

While my construction of sealing means is effective, to prevent access to the container, its application and removal does not mutilati? the container, bungv ring mounting or closingA plug,

and the latter may be sealed as often as desired. lThe sealing member may be formed of thin sheet metal stock and lends itself to economical' production.

To those skilled in the art to which my'invention relates many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the invention. My disclosures and the description herein are purposely illustrative and are not intended to be in any sense limiting.
