'7 Claims.

This invention relates to a duplex package, adapted in a single package to contain two different substances. While adapted for use with any substances, the package is convenient for any materials which preferably should not be mixed until approximately the time of use, such for example as bronzing materials, where the brewing liquid and the finely divided solid material, such as aluminum, bronze, copper alloys or other metal in the form of paste, powder or the like, must be put up and sold together but not mixed until used. The invention however is not limited to use with such materials.

Bronzing material is not mixed until used because upon standing in mixed form the bronze, aluminum or other powder or paste loses its brilliancy by 'a tarnishing or like action. This effect is not so pronounced in the case of aluminum paints but is a serious objection in the case of bronze paints.

Our invention is designed to provide a very convenient package for this class of materials, one which can be made at very low cost so as to be salable in chain and -other stores, but nevertheless provides an attractivepackage which appeals to the purchaser, which is convenient to manipulate, and in which the two materials, liquid and paste or other solid, are kept separate from each other without possibility of contamination of either by the other.

A further object of the invention is to provide a package of this kind which is very compact and utilizes the full volume of both containers, with practically no unfilled space and which,

moreover, supplies to the purchaser a convenient vessel or receptacle in which small portions of the two substances conveniently may be mixed and which serves as a shield or guard to keep the two materials out of contact with each other until used.

Further objects of the invention are in "part obvious and in part will appear more in detail hereinafter.

In the drawing, Fig. 1 represents a sectional elevation of one embodiment of the invention; and Fig. 2 is a similar view, showing still another form.

The package illustrated in the drawing comprises two containers, to-wit, 'a lower container I and an upper container 2. These containers may be of any size, shape or'fo-rm and may be made of any suitable materials. In the form shown the lower container is adapted to contain the liquid material, while the upper container holds the solid material, such as finely divided bronze powder, paste or the like. The lower container therefore should be of a material which is not a'iiected by and will not deleteriously affect the bronzing liquid. Bakelite, metal, glass or other ceramic material is therefore suitable for 5' the lower container. The upper container may be made of any of these materials but transparent glass is preferable because it enables the user to see what is the character of the solid material in the particular package. In one simple arrangement, the two containers are both made of transparent glass.

The lower container I is provided with a reduced neck 3 surrounding the opening forming its mouth, the neck being provided at its end with a transverse annular shoulder or surface l.

The upper container 2 is smaller than the lower container because the quantity of metal powder is'usually of considerably smaller bulk than the bulk of the liquid. This container 2 has its neck 5 reduced and of conical form,- terminating in an open mouth which may be sealed in any suitable manner, as by the cork 6. About midway of its height the upper container 2 is provided with an annular transverse shoulder l, the arrangement being such that when the two containers are assembled in the manner shown in Fig. 1, the shoulders l and l lie opposite to each other. Therefore, the neck and mouth of the smaller upper container 2 enter the cavity of the lower container l. Preferably, sealing means is provided between the two containers, such as an annular gasket 8 lying between the two shoulders d, i. This gasket is compressible and should be made of a suitable material not affected by the bronzing liquid. Specially prepared rubber or similar material is available for this purpose.

The two containers in assembled position may be secured together in any suitable manner, preferably so that they may be readily separated to 4.0 open the package. In the form shown in Fig. 1, securement is accomplished by an annulus or ring 9 made of the same material used to enclose and protect the mouths and corks or bottles containing proprietary remedies, to wit, a cellulose composition of thin form which is applied in a moist condition and which shrinks as it dries so as to form a strong, tight protector. This ring 9 may be transparent, opaque or colored. If colored, it forms an attractive decoration. In assembling the parts, the two containers are squeezed together under pressure, so as to slightly compress the gasket 8 and take up any irregularities in surface, whereupon the ring 9 is applied in wet form and allowed to dry While the containers are under pressure. Ring 9 surrounds two annular beads I0, ll, one on each container, and shrinks to the form of the same, so that it has a firm grip on the lower shoulder I2 of the bead II and the upper shoulder I 3 of the bead I0, and consequently firmly secures the two containers together in sealed form.

In the arrangement shown in Fig. 2 the upper container is illustrated as of glass or suitable ceramic material with its neck threaded, as at I4, to receive a threaded metal cap I5, containing a sealing disk I 6. Whether to use a cork or a screw cap is a matter of choice and of expense and either form may be used in any arrangement. Securement of the two containers to each other is accomplished in the form shown in Fig. 2 by a threaded metal annulus I8, screwed upon threads I9 in the lower container, the upper end of said annulus being beaded or flanged inwardly, as at 20, to obtain a securing grip upon the bead II] of the upper container. In this arrangement therefore the two containers are held together by the grip of the ring l8 upon shoulders upon the two containers. Here again the matter of the securing means for the two containers is one of choice and largely of expense but either the annulus 9 of Fig. 1 or the screw ring I8 of Fig. 2 may be used in any arrangement. The lower container, as stated, is adapted to contain the bronzing liquid, indicated at 2i, while the upper container holds the solid material. We preferably provide means adapted to confine the liquid 2| -to its cavity in container I and. prevent it from contacting with the surfaces of container 2 otherwise exposed to it. One suitable arrangement for this purpose is shown in the drawing. It comprises a small vessel 22 of dish form, having a hollow body portion provided along its upper edge with an annular flange 23 which lies between the gasket 8 and the bead II] of the upper container. This dish may be made of thin sheet metal, such as aluminum,'tin or the like, and serves as a convenient receptacle in which small quantities of the liquid and powder may be mixed for use.

With both forms of the invention, upon opening the package, either by breaking or tearing away the annulus 9 or by unscrewing the ring I8, the upper-container 2 may be lifted ofi and opened. Thereupon the vessel 22 is withdrawn with the fingers and a small quantity of the bronzing liquid is poured into the vessel, which is returned to its place in the mouth of container I. A proper quantity of powder is then poured from container 2 into the liquid in vessel 22 and the liquid and powder are thoroughly mixed and used. After use vessel 22 may be wiped out and container 2 returned to and secured in its original position.

If desired, and as shown in Fig. 1, the wall of container 22, just below the flange 23 may be a close friction fit within the neck of container I, so that by pushing the vessel '22 downward to a home position it compresses and holds compressed the gasket 8, thus retaining the liquid in vessel I under seal and preventing its loss by vaporization or the like. This arrangement is particularly suitable when securement of the two containers is accomplished by the ring 9 which may be destroyed in opening the package, but the arrangement may also be used with the screw ring I8, as in Fig. 2.
