ras,seinbled@relation` The cap" I 2 'includes in general'a horizontal top Wall and a depending annular skirt portion. In the container illustrated the cap is also of double Walled Aconstruction and includes inner. f and outer cup-shaped sheet metal shells and 2l, respectively. 'Ihe top wallof the outer shell 2| is dished upwardly to give the top of thecap a pleasing rounded contour. Upon reference to Fig. 2, it will be seen that the lower edges 22 of the outer rcap shell 2I arevfolded inwardly over the adjacent edges of the inner cap shell 2|Jto 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 I2 is detachably maintained in posiof intertting projections on these parts. Thus,
in the preferred construction illustrated, generally helical ridges or threads 23 are formed in the outer body shell II 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 I2becomes stuck and the ruser 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 example. At `the same time,l the advantages of the smooth interior Wall construction which is so highly desirable in a conta' er of this type are retained. i l
The lower end of the inner shell I0 is carried 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 II. A recess formed in the center of the supporting disk 25 serves to center the same upon insertion of the inner shell I 0. The disk illustrated is provided with an annular upstanding central portion 21, which is dished downwardly as indicated at 28. In the assembly of the container, the disk 25 is first dropped into the outer vshell II 'and rests loosely on the projection 26. The inner shell I 0 is then inserted l into the outer shell and as its lower end wall I3 is received by the recess 28, the disk 25 is properly centered. During the completion `o1' the insertion of the inner shell IU, its edge portion I5 ispress 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 maximum tolerances in their dimensions.
Fig. 3 illustrates a modified form of frictional connection which may be utilized between the inner and outer shells oi a container of the general type described above.
at the top of the outer shell Ila on which aV suitable cap suchpas the cap I2 described above may be telescoped. This neck portion termi- `nates in an upwardly facing shoulder I 8a which This container includes inner and outer shells I Da and I Ia which 'abuts the lower edge of the cap skirt. 'Ihreaded engagement 'between the cap and outer shell II is had by complemental threads identical with those described above, one of the thread indentations 23'L on the outer shell IIa being indivvcated in Fig. 3. In assembling a container having a joint such as-that shown in Fig. 3, it is desirable to forrnthe seam 29.before the lower end `of the space betweenv the vinner fand outer body shells is closed so that an anvil can be inserted therebetween for use in forming the joint. In such case, it is desirable to make the bottom supporting disk of exible material or of such shape that it may be inserted after the insertion of the inner shell Illa.
Although certainpreferred 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 appended claims are intended to cover all modivention.V
I claim as my invention:
'cations Within the spirit and scope of the -in- 1. A container of the class set forth compris-V25 ing a tubular outer shell having an inwardly4x extending projection formed about at least a portion of the lower'end thereof, a supporting disk loosely mounted within said outer shell on said projection, a cup-shaped inner shell inserted d into said outer shell in the assembly of the container, said disk being provided with a centrally located recess therein embracing the lower end of said inner shell, whereby Asaid loosely mounted disk is centered by the lower end of said inner shellupon the insertion thereof, and means securing the upper portions of said shells together in assembled relation.
2. A container of the class set forth comprising a cup-shaped inner shell and an outer shell disposed in spaced relation, the outer shell having its upper end Vportion offset inwardly to forman annular shoulder spaced below, the upper' end oi the outer shell and providing all integral threaded neck portion'on the outer shell, said neck portion `being spaced outwardly from the upper end of the inner shell and said inner shell having an outwardly flaring lip at its` upper end overlapping the upper' end ofthe neck portion of the outer shell and lvclosingtheA upper fend of the space between the two shells, the' over.- 1
lapping portion of the lip .extending down yabout the neck in substantiallyiiush relation withth'e threaded portion of thelatter and constituting an extension thereof, and a cover, having a skirt l.
iitting over the neck portion of .the outer shell and having a screw threaded connection with.. the outer shell through-the integral neckl portiong` thereof.
