New YORK,

Application filed August 16, 1923. Serial No. 657,726.

The invention relates to new and useful improvements in sealed metal containers, and more particularly to a metal container which may be readily opened by breaking the sealing means therefor.

An object of the invention is toprovide a container of the above type wherein the flange on the end and the flange on the body portion of the container are substantially housed by an integral sealing ring, which sealing ring is provided with means at substantially diametrically op osite points whereby the same may be'bro zen.

A further object of the invention is to provide a container-of the above type wherein the inner wall of the sealing ring is cut away so as to facilitate its removal after the same has been broken.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings which show by way of illustration. one embodiment of the invention- Figure 1 is a view partly in side elevation and partly in section showing a container embodying the invention;

Fig.2 is a planview of the same;

. Fig. 3 is an enlarged sectional view on the line 3-3 of Fig. 2;

Fig. 4 is an enlarged sectional view on the line fr-4: of Fig. 2, and

Fig. 5 is an enlarged sectional view on the line 5-5 of Fig.2.

- In the drawings I' have shown my improved sealed container as consisting of a body portion 1 preferably made of metal.

Said body portion has an outwardly projecting flange 2 which is formed-by rolling the metal outwardly, downwardly and inwardly. The body portion is contracted as indicated at 3 so that theextremejouter edge of the flange 2 is substantially over the outer wall of the container body. The flange 2 as shown in the drawings is rolled so as to form a hollow flange. The inner wall 4 of the mouth F of the container is substantiallyvertical.

The container is closed by means of an end 5 which has a central'depression ,6 which provides a vertical wall 7 which is adapted to frictionally engage the inner wall 4 at ,the mouth of the body portion.-" Said end is provided with an outwardly extending flange" 8 which is rolled downwardly and inwardly points. The breaking means as shown in the drawings, and the outer ed e ing means, it will-be understood, of course,

that from certam aspectsof the invention.

the metal forming the flanges may be closed down into substantial contact. Between the flanges there is a sealing means 9 which may be of any suitable character. After the end has been seated in the mouth of the container body, the container is then sealed by means of a sealing ring 10. Said sealing ring 10 is provided with a portion 11 which overlies the flange of the end and also with a portion 12 which extends over into the depression in the end. Said portion 12 is substantially vertical, and in the preferred form of the invention, extends to the full depth of the depression-where it is turned inwardly to form a horizontal ledge 13.

Said sealingrlng has a portion 14 which extends downwardly across the flanges. Said sealing ring is adapted to be turned at 15 underneath the flange on the body por; tion. The sealing ring is placed on the flan es before the part 15 is turned underneat the body flange. A chuck is placed inside. of the ring resting on the horizontal ledge 13, which not only holds the ring, but causes the end to be well seated in the container body, after which the edge 15 is spun or turned in any suitable way underneath the flange 2, and this tightly binds the two flan es together. Inasmuch as the flanges are ollow, they will yield slightly to the pressure of the chuck, and thusit is that there is resiliency in the parts united, which enables them. to be forced into very close contact and the resiliency .of these parts tends to hold the seal tight.

-As clearly shown in Fig. 2 of-thedrawin'gs, Ihave provided a breaking means 16 breaking means at diametrically opposite o posite sides are similar in construction, an a description of one-will answer for the other. This'breaking means is in the form of an inwardly projecting tongue or member for said sealing ring, and there are two which is integral with the wall 12 ofthe sealing ring. The tongue has an openm 17 therethrough for an implement to be use in manipulation of the breaking member to ru turethe'metal ofthe sealing ring.

aid sealing ring is provided with starting cuts indicated at 18 and 1 9 which are substantially in line with the side edges of the breaking tongue or member. The metal is cut through at these points for a short distance from the edge of the flange orledge '13 toward the vertical wall 12, and preferably to the wall 12. In my prior appl1ca-.

tion, Serial No. 657,725, filed of even date. herewith, I have shown a container "closed by asealing ring having a breaking member slmilar tothat above describedat one side It Wlll be noted that this sealing ring Substantially houses the flanges. That is, it extends across the top, down the sides, and un- 'derneath, andthe innerand outer edges of thesealing ring are only separated by a distance slightly greater than the thickness of the metal forming the flanges. The result is that the two flanges will be strongly housed and secured in sealed contact, one with the other. Inasmuch as the cam to which my improved sealing ring is applied is a circular can, it will readily be seen that with a sealing ring of the above character,

if it is brokenonly in one place, it will be extremely diflicult to remove the ring, as it can neither be lifted up nor moved sidewise to disengage it from the flanges.- It will have to be unfolded, which is rather difiicult.

to accomplish. By breaking the ring in two places, however, it can be much more readily unfolded sufficiently to remove it from the container.

As a further means to aid in removing the sealing ring, I have shown the ring as provided with cut away portions 20, 20. These cut away portions are in the inner vertical portion ofthe'sealing ring and extend from a p'olnt' near the inwardly projecting ledge 13 to a point well up to the upper plane of the flange on the cover. By this construc-' .tion, the unfolding of the sealing ring can be very much more readily accomplished, as the amountof metal left in the inner vertlcal ,wall of the ring which lSftO be straightened out has been greatly reduced.

y improved sealedcontainer is. especially adapted for use in connection with goods which are to be put under vacuum, or ressure. It will be understood that the on of the container having the sealing ring necessary.

shown and described the sealing ring as ex- :is preferably applied by the manufacturer.

The container is then packed, after which the other end of the container is put on by the packer.

When it is'desired to open the package, the sealing ring is broken and stri ped from the container, after which the c osing end can be readily removed, and thus the contents rendered accessible. The container may be readily reclosed by placing the end back in the mouth of the container and the vertical wall on the end is of s'uflicient length v to frictionally engage the wall at the mouth of the container, and thus hold the end on the container.

It will readily be seen that the container body with its rolled edge makes a Very neat and attractive container for any use. -Likew1se, where the sealmg ring is entirely separate and independent from the closing end and container body, there are no objectionable raw edges of the metal left on the end or container body after thesealing ring is stripped therefrom.

While I have shown two breaking members oppositely disposed, it is understood that a greater number may be used if found. Furthermore, while I have tending over into the depression of the end or closure for the container, and as having a vertical wall with a horizontal ledge at the lowerend thereof, it will be understood that from certain aspects of the invention, this structure may be changed, the essential feature being that the sealing ring shall extend over the central portion of the container sufliciently to serve as a strong anchorage when the upper edge of the sealing ring is gurlned underneath the flange on the can 0 y. While L'have described the ledge 13 as having starting cuts, it may be that these starting cuts will be only part way cu t through the metal. It is desirable, however to have a starting point for therupture of the metal, so that when the breaking tongue is raised as a lever, the ledge 13ybetween the breaking members being; curved will serve to hold said led e down a ainst the u ward, pry of the brea ing mem ers,'and this will insure that the metal will start toru ture in alinement' with the sidebreaking tongues.

It is obvious that the manner of breaking 121 tion of the ring may be widely varied without departingfrom the spirit of the invention as set forth in the a pended claims.

the sealing ring and the details of construc- Having thus described t e invention, what I claim as new and desire to secure by Letters-Patent, is--' a I 1 1.
