a corporation ofy Illinois Application February 26, 1938, Serial No. 192,712
2" claims. (c1. zzo-1o) AThe invention relates to small jars of the type employed as containers for cold cream, ointments, andthe like and has particular reference to ydouble-walled containers of the type shown in Patent No. 2,044,093, issued June 16, 1936.
In the aforesaid patent there is disclosed a metallic jar composed of inner and outer sheetmetal shells with the inner shell projecting above `,the outer shell and providing a threaded neck portion for the reception. of a screw cap. Because the inner shell, in the patented construction, is frictionally held against rotation relative to the outer shell, difculty has been experienced in removing the cap, the frictional connection being in some instances ineiective to prevent turning of the inner shell with the cap.
In a copending application of Wallace C. Mills,
Serial No. 109,067, the aforesaid diiculty is overcome by a construction in which the threaded neck portion is formed integral with the outer shell rather than the inner shell, but in view of certain advantages inherent in the patented construction in which the threaded neck is integral with the inner shell, the present invention has for its primary object the production of a jar or container of the type shown in said patent providingfin a simple and effectual manner a positive interlock between the shell so as to hold the inner shell against rotation relative to the outer shell while screwing the cap on or off.
More particularly the invention resides in the utilization of a longitudinal seam on the outer shell in providing for an interlock between the two shells.v
Further objects and advantages of the invention will become apparent as the following description proceeds and theV features of novelty which characterize the invention are pointed out y with particularity in the claims annexed to and forming a part of thisv specification.
For a better understanding of thev invention, reference may be had to the accompanying drawing `in which, l
Figure 1 is a perspective view of a sheetmetal container embodying the invention.
Fig. 2 is a central vertical sectional view of the container shown in Fig. l. K
Fig. 3 is an enlarged fragmentary transverse sectional detail view taken approximately in the line 3-3 of Fig. 2 and'illustrating the manner in which the aforesaid interlock is obtained.
For purposes of illustration, the invention has been shown as embodied in a jar or container particularly adapted for coldcream or similar viscous cosmetics andthe like. The particular container illustrated comprises outerv and inner shells designatedk generally bythe numerals I0 and II, respectively, and a cooperatingclosure cap I2.
The outer shell comprises a peripheral side wall I3 and a bottom wall I4. The side is formed from a flat sheet of metal rolled into cylindrical form with the edges of the sheet joined in an interlocking seam I5; and the bottom wall is formed from a metal disk resting upon the edge of an inwardly curled flange I6 at the lower end of the outer shell. Preferably the seam I5 terminates short of the outer side wall I3 to accommodate the bottom wall I4. At its upper end the peripheral side wall I3 terminates in an inwardly bent or curled bead I'I. v
The inner shell, which is made of a diameter somewhat less than the diameter of the outer shell has'a bottom wall I8 and a peripheral sidewall I9. To retain the inner shell in centered relation to the outer shell with an airspace therebetween, the bottom wall I4 of the outer shell is herein shown as formed with a depression 2| shaped to receive the bottom wall of the inner shell. l
To avoid the formation of any joints or crevices,
5 sleeve is' surrounded by thebead I1 of the outer shell so that the upper face of said'beadformsV an upwardly facing shoulder for cooperation with the cap I2. ,-K u
'Ihe cap I2 is preferably. formed with a bowed top and an annular skirt y2li having an integral reverse vflange 21. This flange provides an internal sleeve which is formed with a suitable screw thread 28 for cooperation with the sleeve 22 which is correspondingly threaded as indicated at 29. The proportions are such that the smooth outer peripheral surface of the cap skirt 26 is disposed flush with the outer surface of the peripheral side wall I5 of the outer shell.
For the purpose of providing an interlock between the two shells positively preventing rela- `the inner shell is drawn from a single sheet of "metal and its upper end ,portion terminates in a ange bent outwardly and downwardly to form tive'rotation therebetween, I utilize the seam I5 of the outer shell. As shown in Fig. 3 this seam is so formed as to lie wholly within the outer periphery of the outer shell and therefore provides in eiect an inwardly projecting element or rib upon the inner side of the outer shell. To receive this rib the ared end portion or ange 24 of the sleeve 22 is cut to formy a notch 30. Thus it Will be seen that in the operation of screwing the cap l2 onto or from the neck portion of the container, any tendency of the inner shell to turn relative to the outer shell is prevented by the `engagement of the sides of the notch 30 With the sides' of the seam I5.
I claim as my invention:
l. A double-Walled sheet metalcontainer coniprising an outer shell having a Side wall formed from a flat sheet of metal rolled into cylindrical form and joined in an interlocking vertical seam, an inner shell having an upright side Wall spaced inwardly from the side Wall of the outer shell and having a neck portion depending from its upper end into the upper end of the outer shell, said seam of the outer rshell projecting inwardly to form an elongated internal rib, and said neck portion on the inner shell having a flange notched to receive said rib.
2. A double-Walled sheet metal container cornprising, in combination, an outer shell having a side wall formed from a flat sheet of metal rolled into cylindrical form and joined in a longitudinal seam, a cup shaped inner shell fashioned from a single sheet of metal to form asmoothuninterrupted inner surface, said inner shell being telescoped within said outer shell, with the side Walls of said shells in spaced relation, an integral neck portion on said inner shell depending from its upper end into the upper end of the cuter shell, at least a portion'of the seam on said outer shell projecting inwardly to form a rib, and said neck portion of the inner shell having a flange notched to receive said rib. t
