This invention relates to a double container adapted particularly for the shipment of ingredients for certain kinds of-paint,

such as aluminum and bronze paint, this are 6 ticle having two compartments or container bodies, one for the liquid and the other for the powder.

The object of the present invention is to provide a double container of this kind ineluding two container bodies, one adapted to be fitted inside the other and both adapted to be closed,a-Iid sealed in one closing operation and by the same closing member. I

A further object is to provide a construc- 5 tion wherein not only are both containers closed in one closing operation but wherein each has a gasket seal, the gasket scaling for both container bodies being preferably accomplished with the use of a single gasket.

In the accompanying sheet of drawings, Fig. 1 is a side elevation of my improved double container with both container bodies in closed and sealed condition, parts being broken away; Fig. 2 is an enlarged fragmentary sectional view with the parts in the relative positions which they occupy prior'to the closing operation; Fig. 3 is a similar view after the closing operation; and Fig. 4 is a view similar to Fig. 3 showing'a slight modification. I

My improved double container comprises two container bodies 10 and 11, the former being deeper and of slightly greater diameter than the latter so that the smaller container 11 can he slipped down into the open top of the larger container 10. In the use of this double container for shipment of paint ingredients, the liquid is placed in the-lar er container and the aluminum, bronze or ot er powder in. the container body 11.

It will be observed that the larger or outer container 10 is provided at the top with a roller bead 12 and that the inner container 11 has a straight body portion. of such diameter that it will just fit and slide down inside of the head 12. Furthermore, the inner container body 11 is provided at the top with an outwardly extending flange 13 which overlies the head 12, and this container body has a cover'14 with a depressed part'which fits tightly into the top of the container body 11, the cover having an outwardly extending flange 15 which overlies the flange 13 and preferably extends outwardly somewhat furthe head 12, compressing the ther than the flange 13. In fact, in the preferred embodiment, the outer periphery of the flange 13 is near the circular center line of the head 12 or it may project slightly beyond the same, while the flange 15 projects outwardly beyond the flange 13 as above stated. o

0 In the preferred embodiment of the inven' tion, a single gasket 16 is employed to seal both containers, which gasket is placed between the bead 12 and the flange 13 on the body of the container 11. As far as the broad features of my invention are concerned, it is lmniaterial whether one gasket or two gaskets are utilized, one between the head of the outer container and the flan e'of the inner container, and the other tween the flange of the inner container and the flange of the cover. However, when a single gasket is employed, as illustrated in Figs. 2 and 3, it is important that the flange 15 of the cover project outwardly further than the ,flange 13 of the inner container, as will appear presently.

For the purpose of closing both container bodies, in one closing operation, a sealing ring 18 lsemployed, this being, a continuous ring having separable ends, which can be formed by overlapping the ends and spot welding or otherwise fastening them together, and being provided also with a downwardly extending flange17 which fits around the head 12, and

having a horizontal inwardly extending portion which overlies the flange 15'of the cover 14.

The downwardly extending flange 17 of the sealing ring is preferably continuous, and in the closing operation a closing tool is em ployed which first presses the parts down onto gasket 16, and then crimps spaced portions 17 of the flange 17 inwardly under the bead, leaving between the crimped portions17 uncrimped portions This type of sealing ring and the described method of closing is more fully set forth in a pending application filed by me August 19,

1926, Serial No. 130,215, wherein the sealing ring is employed for the closure of a single container, It may be here stated, however, that in the closing operation the crimped portions 17 are bent inwardly tightly against the underside of the bead and generally incontact with the body of the container beneath its the. bead, these portions being crimped in- "wardlya isubstantially:right angles; and in this crimping operation, the intervening uncrimped port-ions 17 are slightly drawn inwardly and where they merge with thecrimped portions they are curved inwardly,

forming the equivalent of curved arches joining the crimped portions and adding considerably to the strength of the top portion of the closed container.

With the preferred embodiment of my invention wherein a single gasket is employed,

during this closing operation the gasket is not onl highly compressed between the bead 12 an the flange 13 but inasmuch as the flange 15 extends outwardly beyond the flange 13, the

gasket, by its expansion around or outside of the flange 13, and generally also around or outside of the flange 15, efliectively seals the inner container as well, as that leakage of powder from the inner container aswell as,

leakage of liquid from the outer container is effectively prevented by the single gasket 16.

The single gasket, with the sealing ring and with the flanges proportioned substantially as herein described and illustrated, effectively seals both containers as above explained. It is obviously cheaper than a construction employing two gaskets and more economical from the assembling aspect, but, as already stated, I regard it within the scope of my invention to utilize two gaskets, in which event the horizontal flanges on the inner container and cover respectively may extend outwardly co-extensively. The construction when employing two separate gaskets is illustrated in Fig. 4, wherein the flanges on the inner container and cover are designated respectively 13 and 13 and the two gaskets, one between the bead and the flange 13 and the other between the latter and the flange 15 are designated respectively 16 and 16*. With the two gaskets, the sealing of both. container bodies is accomplished at the same time and by the use of one sealing ring, as in the first 1 described construction.

1 as being adapted preferably for receiving respectively the liquid and powder for making aluminum or bronze paint, it is obvious that they may be employed for-the shipment of other materials.

I do not desireto be confined to a sealing ring as an element se arate from andin'dependent of the cover th ugh that arrangement is preferred, for in some instances, the outer sealing flange may be made an integral part of the flange 15 of the cover. In that event, to remove the cover the inwardly crimped portions will be pried outwardly with a suitable tool.

It will be apparent, furthermore, that the location of the gasket 16 beneath the flange 13 of the inner container body is not essential, since the placing of the gasket above that flange will still accomplish the sealing of the two container bodies with a single gasket, so long as the flange 13 extends outwardly a less distance than the head 12 and the peripheral portion 15 of the cover. In both. cases the inner portion of the gasket seals one container body and the outer portion of the gasket seals the other container body. Therefore, I do not desire to be confined to the precise details shown and described but aim in my claims to cover all modifications which do not involve a departure from the spirit and scope of my invention.

Having thus described my invention, what I claim is: I
