12 Claims.

The invention pertainsto small jars of the type employed as containers for cold cream ointments and the like. Containers of this class are commonly made of glass and therefore subject to the objection that they are relatively heavy and susceptible of breakage, so that shipping costs are high and there is danger of injury to the user.

The primary object of my invention is to provide a jar or container of the character indicated embodying a novel and advantageous sheet metal construction, such that the advantages of a glass container are retained without its accompanying disadvantages.

Another object is to provide a jar or container of the character set forth constructed of sheet metal in a manner such as to provide a smooth interior surface having no joints or crevices and an outer surface free from rough and sharp edges.

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

Figure 1 is a perspective view of a sheet metal container constructed in accordance with my invention.

Fig. 2 is a central vertical sectional view through the container as shown in. Fig. 1. I

Fig. 3 is a similar view but showing almodifled 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 form a neck of reduced diameter adapted to receive the skirt of a closure cap. The two shells are moreover constructed to provide an entirely smooth interior surface, with ,the upper end of the neck portion in the form of a broad rounded edge and with the exterior of the container entirely free of rough and sharp edges.

Referring now to Figs. 1 and 2 of thedrawing, a preferred embodiment of the invention comprises spaced inner and outer shells I and 8 having their upper end portions coacting to form a neck 9 of reduced diameter. I II designates a closure cap having a depending skirt ll fitting over the neck 9.

To provide an interior surface entirely free from joints or crevices, I form the inner shell I from a single sheet of metal drawn to provide a bottom wall 9' and a peripheral side wall it, which latter is preferably of uniform diameter from top to bottom. The outer shell 8 comprises a vertical peripheral side wall l2 and a bottom wall I3. The side wall is made from relatively light gauge sheet metal, and has its lower edge portion terminating in an inward and upward curl M. The bottom wall I3, which may be made of metal or other suitable material, is in the form of a disk resting near its peripheral edge upon the upper edge of the curled portion I4 of the outer shell. As shown in Fig. 2, the bottom 8' of the inner shell rests upon the disk l3 which is thus interposed between the curl It and the bottom 9 of the inner shell. Thus the latter is in effect supported against downward movement by the curl l4.

Between the twoperipheral side walls Ill and i2 is formed an annular insulating air space I5 which is closed at its lower end by the peripheral portion of the bottom wall l3 of the outer shell. As shown in Fig. 3, the bottom wall of the outer shell may be omitted, in which event, the inwardly and upwardly curled flange I 4' may engage directly 'with the bottom wall 9" of the inner shell andserve to support the latter directly as well as to close the lower end of the annular space l5.

The neck 9 is preferably formed to provide a broad rounded upward edge 9 for the container, and in securing the two sheets together at the upper end of the container, I employ a construction such as to avoid exposed sharp or rough edges. Accordingly, the upper end of the inner shell has formed integraltherewith a wide flange which is bent outwardly and downwardly to provide an annular collar iii of substantial width forming the outer surface of the neck 9; and I provideat the upper end of the outer shell l2 9. flange ll which is folded inwardly and downwardly in snugly fitting engagement with the lower end portion of the collar l6. Preferably, the latter is spaced outwardly from the peripheral wall of the inner shell to form within the neck portionan upward extension of the annular space l5. By the use of an inwardly bent or folded collar I6 is such as to product a binding fric-' tional contact between the parts, preferably the extreme lower end of the collar is bent or flared outwardly to form a radial abutment lli' engaging with the lower inturned edge of the flange l1. Thus, movement of the inner shell upwardly with respect to the outer shell is positively prevented, while relative downward movement is prevented by the inturned curl or flange M at the bottom of the outer shell acting through the disk IS, in Fig. 2, or directly in Fig. 3, with the bottom of the inner shell.

The cap I0 is preferably formed with a bowed top I! with which the skirt I l is formed integral. Within the cap may be fitted a liner of any suitable material in the form of a flat disk 20 forming between it and the bowed top IS an air space 2|. The lower free edge of the skirt l I is preferably formed with an inwardly and upwardly folded flange 22 forming a smooth rounded edge for the skirt and terminating adjacent the shoulder II. By this arrangement, the skirt H of the cap is disposed substantially in the plane of the peripheral side wall I2 of the outer shell.

If desired, the cap may be fastened onto the body of the container by interengaging screw threads. Thus as shown in Fig. 3, the peripheral skirt I I of the cap may be formed with protruding threads 23, and corresponding outwardly protruding threads 24 formed on the collar I6. I have also shown in Fig. 3, the upper edge of the outer peripheral side wall l2 terminating in a rounded inwardly projecting bead H, as distinguished from the fiat fold employed in the construction shown in Fig. 2.

It will be observed that I have provided a container of the class set forth, which is of a very practical character. Thus, notwithstanding the sheet metal construction employed, an entirely smooth interior surface is provided. Also, the outer surface is free from rough and sharp edges. Accordingly, in the use of the container, all possibility of injury to the fingers is effectually eliminated. Moreover, the container is advantageous as compared to those made of glass in that it is light in weight, which is a material advantage in the case of foreign shipments, and is not subject to breakage either in shipment or in use. The sheet metal construction furthermore lends itself readily to attractive decoration in that the metalllc surfaces may be readily lithographed. Finally, because of the construction employed, the container presents a neat and attractive appearance.
