Patented June 16, 1936 METALLIC JAR John H. Kjellstrom, Rockford, Ill., assignor to J. L. Clark Manufacturing Co., Rockford, Ill., a corporation of Illinois Application November 12, 1934, Serial No. '752,619

9 Claims.

The invention pertains to small metallic jars of the type especiallyA suited for use as a container for cold cream, ointments and the like, and usually made of glass or similar materials.

The primary object of the invention is to provide a jar or container of the character indicated, which is constructed of sheet metal, and which combines the advantages of lightness in weight and attractiveness in appearance with a novel and advantageous construction, such that the interior surface is entirely free from joints or crevices and an outer surface devoid of sharp or raw edges.

A further object is to provide a metallic jar or container of the character indicated, which is of advantageous construction such that a low cost of manufacture is attained.

The objects of the invention thus generally stated together with other and ancillary advantages, are attained by the construction and arrangement illustrated in the accompanying drawing forming part hereof, wherein:

Figure 1 is a perspective view of my improved jar or'container.

Fig. 2 is a central vertical sectional View through the container.

Fig. 3 is a similar view showing a modified construction.

In carrying out my invention, I employ a double walled construction for the container comprising inner and outer shells spaced apart to form a narrow annular air space between them and having their upper end portions coacting to forma neck of reduced diameter adapted to receive the skirt of a closure cap,l and to provide an entirely smooth inner surface and an outer surface lending itself to attractive decoration and avoiding exposed sharp or rough edges. y Referring now to Figs. 1 and 2 of the drawing, a preferred embodiment of the invention comprises spaced outer and inner shells 'I and 8 with their upper end portions coacting to form a neck 9 of reduced external diameter. The container is closed by a cap or cover I0 having a depending skirt II fitting over the neck 9.

The outer shell 1 is made from flat sheet metal of relatively light gauge and comprises a vertical peripheral side wall I2 preferably cylindrical in form. A flat bottom wall I3 in the form of a disk lits snugly within the lower end portion of the peripheral side wall and rests upon the upper edge of an inwardly and upwardly curled flange I4.

The inner shell 8 is preferably drawn from a at sheet of metal to provide a peripheral side (Cl. 22o-10) wall I5 and a bottom wall I5. As herein shown, the bottom wall I5a of the inner shell rests upon the bottom wall I3 of the outer shell although it will be apparent that the latter wall may, if desired, be dispensed with in which event the inner shell may engage directly with the ange I4 of the outer shell.

A feature of primary importance in the provision of a container for receiving cold creams, ointments and the like is the construction employed in forming the neck 9. This construction` comprises in the present instance a reduced upper end portion I6 on the outer peripheral side wall I2, and a flange I1 formed at the upper end of the inner side wall I5. The latter abuts the extreme upper edge of the reduced portion I6 and is thence folded downwardly thereover to form a smooth and relatively wide collar IIa for the neck and at the same time serving to unite the two shells in an interlocking seam.

In forming the reduced upper end portion I6 of the outer shell, an upwardly facing shoulder I8 of substantial radial width is formed, and the ange I1 is made of a width such that the free edge of the collar IIa formed thereby abuts 2'5 the shoulder I8. Thus the shoulder effectually covers the lower free edge of the collar I'Iab thereby serving to prevent injury to the hand of the user.

Outwardly of the collar Ile the shoulder I8, because of its substantial width, opposes the lower end of the cap skirt II which may thus be disposed substantially in the plane of the outer side wall I2. Preferably, the lower edge of the skirt II is curled as indicated at I9 so as to conceal the sharp edge of the metal. Also, as will be evident, this curled edge of the skirt forms a projecting bead facilitating the removal of the cover.

By the construction thus employed, the two shells are firmly secured together, the interior of the container is of substantially uniform diameter from top to bottom, and the inner surface entirely devoid of seams, crevices, joints or rough edges, while the upper end of the container ter- 40 minates in a smooth rounded edge. Externally of the container, sharp or rough edges are effectually concealed, and when the cap or cover is in position the container is of substantially uniform diameter from top to bottom with the exception of the bead I9. Finally, a narrow insulating dead air space 20 is formed between the two shells which space is closed at its upper end by the shoulder I3 and at its lower end by the bottom wall I3 of the outer shell.

The cap l0 may be made from a flat sheet of metal drawn to provide the depending skirt H. Preferably, the top of the cap is formed with a slight upward bulge, and within the cap is tted a fiat liner 2| engageable near its peripheral edge with the upper rounded edge of the neck 9. Due to the bulge in the top wall of the cap, an insulating dead air space 22 is formed within the cap.

In Fig. 3 of the drawing, a slightly different embodiment of the invention is illustrated. In this instance, the neck of the container, while constructed in the manner above set forth in connection with Fig. 2, is formed with screw threads as indicated at 23, and the skirt of the cap correspondingly threaded as at 24, so that the cover may be screwed into position. It will be observed that the screw threads 23 are formed through the three thicknesses of material constituting the neck.

In this latter embodiment, the bottom construction of the container is also somewhat different. Thus, the bottom wall 25 of the outer shell is formed with a peripheral flange united by means of a seam 26 with the lower end portion of the outer wall of the container.

It will be observed that I have provided a sheet metal container of a very practical character, especially adapted for use as a container for creams, ointments and the like. Such a container is especially advantageous as compared to the commonly used glass jars in that it is light in weight, which is a material advantage in the case of foreign shipments, and in that it is not subject to breakage either when the container is accidentally dropped or when removing the cover. The sheet metal construction furthermore lends itself readily to attractive decoration in that the outer metallic surfaces may be readily lithographed, and moreover, because of the construction employed, the container presents a neat and attractive appearance.
