9 Claims.'

This invention relates primarily to jars of the type disclosed in my co-pending applications for Jars, Serial No. 18,031, led April 24, 1935, Seri-a1 No, 103,553, filed October 1, 1936, which jars are primarily intended for containing cosmetic preparations including salves, cold creams and other preparations of a pastelike consistency and Ialso including powders. A jar of this type consists of two separate thin-walled members, each of which may be molded from a material of the synthetic resin class although this is not essential as concerns the outer member. The inner member is formed for engagement with a closure or cap and is adapted for containing the cream or other cosmetic preparation; and the outer or base member serves to support the inner or containing member and to provide the desired eXterior contour or design. The two members are engaged with each other in such manner as to o provide resistance to separation and in such manner as to prevent relative rotation.

The principal object of the present invention is to provide in a jar of the type described a suitable means for connecting the inner or containing member with the outer or base member, which means is particularly adapted for use with a base member formed of sheet metal.

In accordance with one phase of the invention there is provided a connector which is structurally separate from both of the said members and which is preferably positioned below the containing member and entirely within the cup-shaped base member. The connector is preferably formed of sheet metal and is preferably provided with teeth intended to engage and bite into the smooth interior surface of the base member.

In the accompanying drawing I have shown one suitable embodiment of the invention, but it will be understood that the drawing is intended for illustrative purposes only and is not to be construed as defining or limiting the scope of the invention, the claims forming a part of this specication being relied upon for that purpose.

Of the drawing:

Fig. 1 is a plan View of a jar embodying the invention.

Fig. 2 is a combined elevational and vertical sectional view of the jar, the section being taken along the line 2--2 of Fig. 3.

Fig. 3 is a bottom view of the inner or containing member.

Figs. 4 and 5 are plan and edge views respectively of the connector.

Fig. 6 is a combined elevational and vertical sectional view showing the relationship of the parts at an intermediate stage of assembly.

Referring to the drawing, I and 2 represent respectively the two main members constituting the jar. The member I is designated as` the inner or containing member, and the member 2 is desig- :cated as the outer or base member.

rIhe inner or containing member I is a thinwalled cup-shaped member preferably molded from a material of the synthetic resin class and it is preferably of such shape that its interior diameter at the top is at least as large as the interior diameter below the top. The bottomwall of the containing member is indicated at 3. The containing member I is threaded adjacent its upper periphery as indicated at 4, being thus adapted for engagement with a threaded closure 5 of the cap type. n

The outer or base member 2 is so related to the containing member I as to permit the said containing member to be assembled vertically downward with respect thereto. The base member has a peripheral annular portion 6 which is in engagement adjacent its top with an annular portion of thecontaining member I, and the base member preferably has a bottom wall I which is positioned beneath the containing member. While I do not necessarily so limit myself, the annular portion 6 of the base member is shown as surrounding the entire lower portion of the containing member and as being spaced outward therefrom. The containing member I is provided with a thin outward projecting annular flange 8 immediately below the threads at 4, this flange being of such size and so positioned that the bottom surface thereof is engaged by the top edge of the annular portion 6 of the base member. Preferably the outer or base member 2 is formed of sheet metal, the said member having walls of substantially uniform thickness throughout and being provided with smooth interior surfaces.

In accordance with one phase of the present invention I provide a sheet metal connecting means near the bottom of the base member which engages the containing member to hold the said containing and base members in assembled relationship. Preferably and as shown, there is a metallic connector 9 which is structurally separate from the base member and located adjacent the bottom wall 'I thereof and entirely within the base member. The connector 9 is preferably formed of sheet metal andis positioned below the bottom wall 3 of the containing member I, l f

The connecting means, such as the connector 9, is firmly connected with the containing member and for this purpose the containing member is provided With one or more downward projecting plugs I0, l on the bottom thereof. As shown there are four such plugs substantially uniformly spaced with respect to each other. The sheet metal connecting means is provided with holes Il, Il corresponding in size and location to the plugs on the containing member. These holes are initially slightly smaller than the plugs so that the plugs can be entered in the holes only by the use of considerable force. In order to facilitate entry of the plugs in the holes and at the same time permit rm engagement, the said holes are provided with slots Ila, Ila. inasmuch as the holes are initially slightly smaller than the plugs, it will be seen that the plugs upon entering will slightly deflect the metal between adjacent slots. The metallic sectors at the edges of the holes are, by reason of their own resiliency, thus held firmly in engagement with the plugs, and the metal tends to bite into the plugs to resist any attempt to withdraw them.

When there is a structurally separate connector such as 9, it is of such size and shape at its opposite edges that it will iirmly engage the opposite interior surfaces of the base member 2. Preferably the connector 9 is provided with oppositely disposed teeth l2, l2, the transverse dimension between the ends of opposite teeth being slightly greater than the interior diameter of the base member 2.

In assembly the inner or containing member I is rst assembled with the connector 9 by forcing the plugs I0, l into the holes Il, Il as already described, and'then the containing member and connector are placed on the base member as indicated in Fig. 6. By applying downward pressure to the containing member,the said member, together with the connector, is forced downward into the fully assembled position as shown in Fig. 2. During such downward movement the edge portionsof the connector 9 are deflected relatively upward as shown in Fig. 2, the resiliency of the metal of the connector tending to force the teeth I2, I2 into rm engagement with the smooth interior vertical surface of the base member. The connector thus serves to firmly hold the containing and base members in normal assembled relationship, and any attempt to separate the members would merely serve to force the edge portions of the connector into even firmer engagement with the base member.
