J Nov. 5, 1929. I J. E. GUNTE CONTAINER Filed Jan. 50, 1926 ATTORNEY;
Patented Nov. 5, 1929 UNITED STATES JAMES E. GUNTER, F BALTIMORE, MARYLAND CONTAINER Application filed January 30, 1926.- Serial No. 84,826.
My invention relates to new'and useful improvements in closures for containers, and more particularly to one in which the closure .retainingmeans may be readily removed, and that without destroying the further usefulness of the container. 4
While the invention is applicable to a wide variety of containers, it is particularly useful on a sanitary friction top metal container,
on which the cover may be soldered by a film of readily breakable solder. I
An object of the invention is to provide a sealed closure which may be economically manufactured and applied and which can be easily and certainly opened without the use of any tool, and the cap of which, after the container is opened may be satisfactorily used for a sealing cover for the container while the .contents are being used.
Another object is to provide a seal which will withstand a high internal pressure during the heating of the contents or the rough handling of the container, and thus avoid the breaking of the seal or the blowing off of l the cap during heating or handling.
. parent from the preferred form shown in the accompanying drawings in which:
Figure 1 is a front view of the top, a part of the body of the container and the retaining ring with the cap and ring in place.
Fig. 2 is a cross section of line 22 of Fig. 1, looking in the direction of the arrows.
Fig. 3 is a view similar to Fig. 1 with the cap and ring removed. Fig. 4 is across section on line 44: of
- i Fig. 3.
Similar numerals refer to similar parts throughout the several views.
The container body 1 has preferably a flared mouth 2 around which, near its upper end is a ridge 3. Cover or cap Lhas a substantially vertical section 5 making a tight friction engagement with a corresponding section of the container wall. From this section the cap flares outwardly and has an outer wall bent downwardly over the container edge.
The outer edge of the cover and the top portion of the container wall form a space which contains a ring 6, preferably, though not necessarily, discontinuous, as shown in Fig. 1. The ring has a handle 7 projecting from it and from the space, so that pulling downwardly on the ring will permit its removal and spread the outer cap wall, thus allowing it to be removed. The flared top of the container does not extend outwardly too farto permit the removal of the cap when the ring has been removed.
In practice, the container is preferably made with a continuous ridge, the ring placed around the container above the ridge, and the cover placedin the mouth of the container. A chuck is then placed in the inner part of the cap and the cap edge is either rolled down around the ring or is bent downwardly and inwardly by any other means. ing handle in the process compresses the ridge, mashing it inwardly, so that it takes a path substantially parallel to the outwardly facing inner wall of the cap. The bead or ridge and the ring are so small that the mashed part of the container simply flattens out, as shown in dotted lines in Fig. 2 and in Figs. 3 and 4. Very little additional pressure is required for this flattening process, so the tool surrounding the cap passes unobstructedly and regularly over the projecting handle. Prior to placing the ring around the-container, the handle portion is preferably bent downwardly and inwardly, in the The project- I I form which it will ultimately assume so that the bending tool will not have to do this step.
It is apparent that the outer wall of the cap is unbroken in its ring surrounding course, that this gives it strength peripherally and thus holds the cap firmly on the container.
When a soldered joint is desired, a small film of solder may be run around the edge of the cap wall and the ridge, and this film can be readily broken by pulling the ring out. The continuous outer wall cap surface keeps the solder from running out and it cannot by any chance get into the can, as is the case with an ordinary friction top container.
The retaining ring maybe made any shape in cross section or of any material which will hold its form under the stresses to which it is subjected and which has sufflcient tensile strength to be pulled out. Many changes may be made in the invention, for instance, the ridge may be of any suitable cross-section or may be discontinuous.
I claim:

A container seam for the end of a container comprising, a container wall flaring outwardly toward said end, a retaining ring surrounding said outwardly flaring container wall near said end, said ring having a projecting handle,,means projecting from said outwardly flaring container wall to hold said ring outwardly thereon, the periphery of the portion of said outwardly flaring wall within said ring being greater than that of the con tainer wall below said means, and a cap having a clown-turned wall partially surrounding said ring laterally and firmly holding it against said container wall.

4.. A container seam for the end of a container comprising, a container wall having a substantially vertical section and a section flaring outwardly toward said end, a retaining ring surrounding said outwardly flaring section near said end, said ring having a projecting handle, the periphery of the portion of said outwardly flaring section within said ring being greater than that of the substantially vertical section of the container wall, means projecting from said container wall to hold said ring outwardly on said outwardly flaring section, and a cap having an outer down-turned wall partially surrounding said ring laterally and firmly holding it against said container wall, the cap also having an inner outwardly facing wall engaging peripherally the substantially vertical section of said container wall.
5. A container seam for the end of a container comprising, a container wall flaring outwardly toward said end, a retaining ring surrounding said outwardly flaring container wall near said end, said ring having a handle projecting downwardly from said end of said container and inwardly from said ring, means projecting from said outwardly flaring container wall to hold said ring outwardly thereon, the periphery of the portion of said outwardly flaring wall within said ring being greater than that of the container wall below said means, and a cap having a down-turned wall partially surrounding said ring laterally and firmly holding it against said container wall.
6. A container seam for the end of a container comprising, a container wall, a retaining ring surrounding the container wall near said end, said ring having a projecting handle, a discontinuous ridge around and projecting outwardly from said wall below said ring, a cap having a down-turned wall partially surrounding said ring laterally and terminating adjacent said ridge, the internal surface of said down-turned wall not being bulged outwardly where said handle projects. V
7. A container seam for the end of a container comprising, a container wall, a retaining ring surrounding the container wall near said end, said ring having a projecting handle, a discontinuous ridge around and pro-' jecting outwardly from said wall below said ring, a cap having a down-turned wall par tially surrounding said ring and terminating adjacent said ridge, the internal surface of said downturned wall not being bulged outwardly where said handle projects, and said terminating wall and ridge being soldered together.
