METAL CONTAINER Filed Dec. 5, 1934 Patented June 28, i93$ ttithitt the ,mm. CONTAINER, Karl Wilhelm Mauser, Waldech, Germany Applicationllecembcr 3, 1934, Serial No. 755,828

In Germany December 11, I933 Glaims. e11 220-61) In the metal containers as hitherto constructed with a ring-shaped'seating for receiving the cover and its fastening means, the seating is fixed to the container wall in such amanner that it 5, projects into the interior of the container. This has the disadvantage, that normally the container contents cannot be entirely removed. The residues remaining in the container can only be removed by an inconvenient manipulation.

in It has already been attempted to arrange the ring-shaped seating so as to be flush with the interior of thecontainer, by the container wall being drawn out in such a manner that it either embraced the ring-shaped seating from the outside or. engaged in it from within. In the former case the construction .was unsatisfactory, owing to the circumstance that the thin material forming the wall would not stand such a treatment and became torn. In the latter case it was found that there was the disadvantage that there was no certainty of the' sheet forming the wall bearing firmly in the ring-shaped seating and that.

the'rirg was still further loosenedthroughexternal influences. On the closuremeans being stressed, the part of the ring-shaped seating which was formed from the material of the wall.

yielded elastically, making it impossible to obtain atight closure. A further greatdisadvantage in packing containers having a ring-shaped. 50 seating was, that for each of the usual kinds of "closure adapted to the particular purpose a different ring-shaped seating had to be used. Those.

. skilled in the art aim at making the metal pack- -ing containers suitable for a great variety of pur- 35 poses, so that for one. and the same container all theusual kinds of closures maybe'used.

The present invention provides a perfectly satisfactory solution of the problem and at the same time overcomes all the above disadvan- 40 tages as regards the method of, iixing the ring shaped seating. I J I The invention will now be more particularly described with reference to' the accompany drawing. Figs. ,1 to 6 show constructional ex- 45 amples in which the ring-shaped seating a formed from flat or profiled strip-metal is flush.

with the interior of'the container. In Figs. 1

' to 6 the connection. between the ring-shaped seating a and the container wall-bis eflected by so the part c which forms the extension of the lower abutment flange ebeing doubly beaded over with the container rim to form four layers of material. This double beading bears in Figs.

1, 2,4, 5 and-36 closelyagainst the lower abut-" 5 ment flange e of the ring-shaped seating a. .Fig.

3 shows a constructional form of the ring-shaped seating, in which the double beading b, c bears closely against the container wall I), the abut ment flange e covering the head of the double beading and thereby securing the beaded con- 5 nection. In those cases in which the beaded connection is to be made fluid tight a packing a may be headed in as well, as is shown in Fig. 2. In the described construction of the ring-shaped seating according to Figs. 1 to 6 the cover-d is 10 seated on the lower abutment e of the ringshaped seating, which is unafiected by the beading operation.

A packing ring 1' of rubber or any other ,suitable material is placed between the cover 11 and 15 v the beading operation may be used; a protective .hoop i being providedfcr reinforcing the ringshaped seating and for strengthening the con-.'' tainer head. Such a protective hoop is also 25 shown in the constructional forms of Figs. 5 and 6. ,TheJing-shaped seating according to Fig. 3 is .of uniform thickness in-that part which constitutes the abutment for the ring'and the cover, while the beaded part is suitably thinner for facilitating the heading operation.

In the constructional forms shown in Figs. 1

I to 3 the ringshaped seating' is of substantially rectangular cross-section and allows only of the employment of closures employing-wedge-shaped rings and locking members.

- Figs. 1-6 illustrate constructions of ring-shaped. seatings having'an approximately semicircular.

or ellipse-shaped cross-section. This'form o! ring-shaped seating enables all the usualkinds 40 of closure to be used, such, for example, as closures'empioymg wedge rings,- tension rings and locking members, with one and the same ringshaped seating. Thus Fig. 4 shows}; wedgeshaped ring closure in which the wedge ring m 'actsas the closing means;;Flg.g5 shows a locking closure with lock members 1: and finally Fig.

6 shows a tension ring closure in which the ten''- sion ring 0 forms the closing means. As is shown in Fig. 5, the cover d maybe provided with a rirn'p extending over the ring-shaped seating a. This rim serves besides other purposes that of acting as a protection against the falling .in of dirt which might get into the interior of the container, -on the cover being opened. In the constructional form shownin Fig. 6 it will be seen that the rim/1: of the cover also can act as an abutment for a second'gasket.

This part of the invention satisfies an urgen requirement, the economic value of which is of the greatest importance. The manufacture of the metal containers is greatly simplified, owing to the circumstance that the separate manufacture of the parts of the ring -shaped seating required for the greatly differing closing means are replaced by a standard ring-shaped seat: Eng. It should also be borne in mind, that the ring-shaped seating of semicircular form can be made far more simply and cheaply than the parts of the ring-shaped seating 'hitirertc used. The user is now put in the position of being able to use one and the same packing container for the most varied purposes which entail the employment of a variety of closing means. Fi-

nally the mode of fixing the ring-shaped seating ing means for the cover, and a ring-shaped seating for the cover and fastening means, which seating consists of strip metal and has a substantially U-shaped'part for receiving the cover and fastening means, and a lower part, .a prolongation of which is folded together with the edge of the container wall 0 form at least four layers of material at' the joint, and which at its innermost part is flush with the interior of the container wall.

2. A metal container as claimed in claim 1, in which the prolongation of the lower part of the seating and the container wall are folded together so that the layers of material lie parallel to the lower limb of the U-shaped part.

3. A metal container as claimed in claim 1, in which the prolongation of the lower part of the seating and the container wall are folded together so that the layers of material lie parallel to" the container wall.

4. A metal container as claimed in claim 1,

in which the U-shaped part is of rounded shape.

5. A metal container as claimed in claim 1, in which the prolongation of the lower part of the seating and the container wall are folded together so that the layers of material lie parallel to the lower limb of the U-shaped part, and having a protective hoop fitting over the U-shaped part and the layers of folded material.
