1 Claim.

This invention relates to a can of that type generally used in connection with metallic bronzes, wherein a thinner or vehicle is placed within the body of the can and a metallic bronze ,y paste is held within a tray removably supported within the top of the can, the tray and can proper being closed by a frictional or snap-on lid or cover.

In one of the previous can structures of this general type, as exemplified in the Seipt Patent No. 1,955,610, a triple seal is provided by the frictional engagement between the side walls of an annulus attached to the body of the can, an annulus integral with the tray and an annulus integral with the cover or lid. While such a triple seal prevents intermingling of the contents of the can with the contents of the tray, or leakage of either of these contents to theoutside of the can, it nevertheless renders very diflicult no the opening of the can and makes impossible the resealing of the can after partial use of the contents. In the rst opening of the can, where such a triple seal is provided, one or more of the internesting annular portions is bound to become sprung and the renesting of the annular portions in frictional engagement cannot be easily effected so as again to provide a tight seal. It is also more diflicult in the iirst instance to open such a can. Q In accordance with the principles of this invention, the cover or lid is provided with an annular portion that directly and frictionally engages an annulus attached to the body of the can, so as to provide merely a double seal, and the tray or inner receptacle merely rests upon an inner peripheral bead formed on the annulus oi the can, without any annulus being provided on the tray for frictionally internesting with the annular portion of the body and cover. By this 40 construction, the opening of the can in the first instance is greatly facilitated and springing of either of the annular portions is eliminated, thereby permitting repeated resealing of the can during use. Also, in accordance with this invention, a gasket is provided between a curved ange formed on the tray and correspondingly curved portions formed either on the annulus of the can or on the cover itself. The tray may thus be removed simply by lifting it out of the can and need not be pried up, as in the case of the prior art structure just described.

It is therefore an important object of this invention to provide an improved can of the dual container type, wherein the opening of the can is greatly facilitated and the can may be repeatedly sealed during use of its contents without danger of springing portions of the interengaging parts of the can, tray or cover so as to make a leaky joint.

It is a further important object of this invenf tion to provide a can or receptacle of the dual purpose type wherein the cover is provided with an annular portion for frictionally nesting directly in an annulus formed inwardly of the topof the can body, and a tray is removably supm ported and sealed between the cover and annulus of the can body without frictionally internesting with either.

Other and further important objects of this invention will be apparent from the disclosures in the speciiication and the accompanying drawing.

This invention (in a preferred form) is illustrated in the drawing and hereinafter more fully described.

On the drawing:

Figure l is a top plan view of a can embodying the principles of my invention.

Figure 2 is an enlarged fragmentary sectional view taken substantially on the line II-l of ,25 Fig. l.

Figure 3 is a further enlarged detail sectional view showing the sealing construction.

Figure 4 is an enlarged detail sectional View, similar to that of Fig. 3, but of a modified type of construction.

As shown on the drawing:

The reference numeral I0 indicates generally a can, or receptacle, embodying the principles of my invention, and comprises a body portion Il having an inwardly directed annulus I2 secured, as by an interlocking crimping bead I3, to the top edge oi said body portion II. Said annulus I2 is provided with a U-shaped groove I4, the inner upper edge of which is beaded as at I5.

A tray I6 having a peripheral, narrow curved flange I1 is removably supported within the can with said flange II (Figs. 2 and 3) resting directly upon the bead I5. The curved flange I'l conforms with the curvature of said bead I5 and the fiange terminates short of the vertical leg I8 of the annular groove I4. The tray I5 may thus be removed by merely lifting it oi of the supporting bead I5.

A cover I9 for both the tray I6 and the can body proper, is provided with a peripheral annular portion adapted to frictionally nest in the annulus I4. The peripheral upper edge of the annular portion 20 is provided with a bead 2|, which, in assembled position, is inwardly spaced from the crimped edge I3 to permit the insertion of a tool or other instrument for prying up the lid I9. Since the annular portion 20 is in direct frictional engagement with the legs I8 and 22 only of the annulus I4, the lid I9 may be readily pried up Without danger of springing any of the intertting portions.

Between the central plane portions 23 of the lid I9 and the annular portions 20 there is provided an upwardly convex annular portion 24 of slightly larger radius of curvature than that of the curved peripheral flange II. A gasket 25 (Figs, 2 and 3) of suitable material, such as rubber, rubber composition or the like, is secured in the under surface of the annular portion 24 to seal the joints between said annular portion and the curved peripheral ilange 25, against which the gasket is pressed when the cover is assembled in place. It will be understood that a separate gasket may be used, but for convenience it is preferable to have the gasket 25 adhesively secured as indicated.

In the modified form of my invention, as illustrated in Fig. 4, similar parts of the can construction are indicated by similar reference numerals, the only material difference in this modied construction being in the positioning of the gasket. In the modified form of construction, a gasket 26 is secured to the undersurface of the peripheral ilange I'I, so as to seal the joint between said iiange and the beaded edge I5. The joint between the upper surface of the peripheral ange II and the intermediate annular portion 24 of the lid is adequately sealed against leakage to the outside of the can by the frictional intertting surfaces of the annulus I4 and the annular portions 20 of the cover, There is a sufficiently close surface t between the curved peripheral flange l1 and the annular portion 24 to prevent leakage of the contents of the tray I 6 into the body of the can itself. Furthermore, any such leakage as might occur Would be negligible both because of the xed pastry character of the contents of the tray I6 and because some slight leakage of the tray contents into the body of the can would not be harmful anyway.

In both modifications of the invention, it Will be apparent that once the cover has been pried open, the tray can be merely lifted up from the supporting bead I5, so that only a single prying action is required. This construction not only facilitates the opening and resealing of the can, but reduces the amount of sheet metal required in the construction of the can.

This application is a continuation-in-part of my application entitled Can, Serial No. 109,820, led November 9, 1936, and now matured into Patent No. 2,120,357.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

In a can of the class described, a body portion having an interior annulus secured to the top of the body and shaped to denne an inwardly extending ledge of substantial width and at a substantial distance below the top of said body, said annulus being also shaped to dene a U-shaped groove formed of opposed and spaced walls of unequal depth, the inner wall extending a substantial distance above said ledge and having its free end terminating in a bead, an inner tray of substantial depth and cubical capacity having an upstanding wall terminating at its free end in a curved flange resting on said bead, said curved flange terminating short of said groove a gasket seated on said flange, and a cover having an inner portion dlshed and bounded by a curved portion seated on said gasket and merging into a U-shaped portion entered in said groove to frictionally engage the walls thereof, said U- shaped portion having an outer annular wall terminating at its upper end substantially flush with the top of said body portion.
