2,186,338 (Cl. 220—10) cap. on? or off. The particular. ‘ container illustrated. comprises inner and outer shells designated /generallyby; the-numerals 10 ^!and I I, respectively, and a cooperating closure cap 12. _

To provide an interior surf ace entirely free ⁶from joints .or .‘crevices,’ , the: inner shell 10 is preferably cup-shaped rand formed from 'a single sheet of metal drawn to provide a bottom wall 13 and a side wall: I4^:'? terminating in a comparatively wide outwardly flaring lip (5 extend- ¹⁰ing entirely about the upper edge of the inner which the contentsoftthe jar may become lodged, ^IOaespecially while removing the same. In the preferredconstruction illustrated, the lip 15 also includes : a.downwardly projecting portion 16 disposed in spaced relation with respect to the adjacent upper end of the side wall of the shell and 20. cooperating with the adjacent edge of the outer shell li to hold the same in assembled relation as-iis hereinafter described in greater: detail.

The upper end portion of the outer shell 11 is ' inset as indicated: at I7 in- order to form a neck. :25 · of reduced diameter on which the cap 12 is telescoped- so that the exterior surface of the sides’ of the cap form a smooth continuation of the exterior .side· walls.of the outer shell? II. . It will__ lar upwardly facing shoulder 18 on which the lower- edge - of . the = cap - rests. A second and smaller shoulder 19 is preferably formed in the outer shell II and the edge of the inner shell rests against this shoulder. In assembling the 35 inner and outer shells, the upper edge of the outer shell 11 is preferably press fitted within the· downwardly extending. portion 16 of the inner shell 10 so as to fractionally retain, the shells in assembled; relation. 40::

The cap 12 includes in general a horizontal top wall and a depending annular skirt portion. In the container illustrated the cap is also of double walled construction and includes inner and outer cup-shaped sheet metal shells 20 and 21, 45 respectively. The top wall of the outer shell 21 is dished upwardly to give the top of the cap a pleasing rounded contour. Upon reference to Fig. 2, it will be seen that the lower edges 22 of the outer cap shell 21 are folded inwardly over 50 the adjacent edges of the inner cap shell 20 to form a smooth lower edge for the cap and at the same time, retain the shells in assembled relation with a firm clamping action.

The cap 12 is detachably maintained in posi- 55

The invention rela.tes to small jars of the type employed as containers for cold cream, ointments, and the like. It has heretofore been pro. posed to construct such containers of cooperating 5/inner? and outer sheet metal shells, as, for example,· in the · manner shown in Patent No.· 2,044.093, issued . June 16, 1936,: in order to reduce; the weight >and^rfrangibility of the article as. compared. to · a similar, container made of 10 -glass, and also. to .obtain.other advantages resultΤίτο* ίΤτΉτΐτ tiTip use of a metal'» container· - ~ _

Figure 1 is a perspective view of a sheet metal container embodying the invention. ,

SB·?, Fig. 2 is an enlarged side elevation, partly in section, of the container shown in Fig. 1.

Fig.' 3 is: a fragmentary: sectional detail view illustrating particularly a modified form of joint between the inner and outer shells of a con4ni'/tainer;such as that shown in Fig. 1.

^r For purposes of illustration, the invention has been shown as embodied in a jar or container particularly adapted for cold cream or similar viscous cosmetics and the like. This container is 46 of a double walled construction made up of inner and outer sheet metal shells which are preferably secured together by a simple frictional joint. The shells are so fashioned that the interior of the container will have an entirely 60 smooth surface terminating in a broad rounded edge at the top of the container while the outer shell is fashioned for threaded engagement with a closure cap which is out of? contact with the inner shell, thus preventing dislodgment of the „ frictional inter-shell joint when screwing the

2,186,388 tion by means forming a screw threaded engagement with the outer shell, preferably in the form of interfitting projections on these parts. Thus, in the preferred construction illustrated, gener5 ally helical ridges or threads 23 are formed in the outer body shell 11 and cooperate with complementary inwardly extending ridges or threads 24 formed in the inner cap shell 20. It will thus be seen that even if the cap 12 becomes stuck 10 and the user exerts a strong torsional force in attempting to unscrew it, there will be no danger of twisting the inner and outer shells with respect to each other as would be the case if the cap were threaded on the inner shell, for ex15 ample. At the same time, the advantages of the smooth interior wall construction which is so highly desirable in a container of this type are retained.

The lower end of the inner shell 10 is carried 20 by a supporting disk 25 loosely mounted within the outer shell II. Thus, this disk rests on the inwardly and upwardly curled portion 26 of the outer shell 11. A recess formed in the center of the supporting disk 25 serves to center the same 25 upon insertion of the inner shell fO. The disk illustrated is provided with an annular upstanding central portion 27, which is dished downwardly as indicated at 28. In the assembly of the container, the disk 25 is first dropped into 30 the outer shell I f and rests loosely on the projection 26. The inner shell 10 is then inserted into the outer shell and as its lower end wall 13 is received by the recess 28, the disk 25 is properly centered. During the completion of the 35 insertion of the inner shell 10, its edge portion 16 is press fitted over the upper edge of the outer shell II. It will thus be seen that the assembly operation is very simple and that the component parts are also of simple construction with maxi40 mum tolerances in their dimensions.

Fig. 3 illustrates a modified form of frictional connection which may be utilized between the inner and outer shells of a container of the general type described above. This container 45 includes inner and outer shells IO^a and I l^a which may be identical in construction with the shells 10 and 11 described above except for the interlocking edge portions thereof. Thus, the upper end of the cup-shaped inner sheet metal shell 50 10^a terminates in an outwardly flaring smooth lip I5^a of substantial width which forms a smooth continuation of the inner side walls of the shell. The edge of the lip I5^a is bent inwardly and interlocked with the adjacent upper edge of the 55 outer shell I l^a to form a double seam as indicated at 29. An inset neck portion I7^a is formed at the top of the outer shell I i^a on which a suitable cap such as the cap 12 described above may be telescoped. This neck portion termi60 nates in an upwardly facing shoulder 18^a which abuts the lower edge of the cap skirt. Threaded engagement between the cap and outer shell I l^ais had by complemental threads identical with those described above, one of the thread indentations 23^a on the outer shell li^a being indi- ⁸cated in Fig. 3. In assembling a container having a joint such as that shown in Fig. 3, it is desirable to form,the seam 29, before the lower end of the space between the inner and outer body shells is closed so that an anvil can be 10 inserted therebetween for use in forming the joint. In such case, it is desirable to make the bottom supporting disk of flexible material or of such shape that it may be inserted after the insertion of the inner shell 10^a. 15

Although certain preferred embodiments of the invention have been shown and described in some detail for purposes of illustration, there is no intention to thereby limit the invention to such embodiments but, on the other hand, the ap- ²⁰pended claims are intended to cover all modifications within the spirit and scope of the invention.
