4 Claims.

This invention relates primarily to jars oi the type disclosed in my co-pending application for Jars, Serial No. 18,031, iiled April 24, 1935, which Jars are primarily intended for containing cos- 5 metio preparations including salves, cold creams and other preparations of a pastelike consistency and also 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. 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 provide resistance to separation and in such manner as to prevent relative rotation.

In accordance with the present invention a structurally separate exteriorly exposed retaining ring is provided for positively connecting the two members. 'I'his ring not only effects positive connection, but it also provides for pleasing color contrasts.

In the accompanying drawing I have shown two embodiments of the invention, but it will be understood that the drawing is intended for illustrative purposes only and is not to be construed as deiining 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 side view of a jar embodying the invention, a portion of the closure being broken away to show the closure retaining threads..

Fig. 2 is a vertical central sectional view through the jar shown in Fig. 1, the containing member being shown partly in elevation and the o closure being omitted.

Y Fig. 3 is a combined side and sectional view of an alternative jar embodying the invention.

Referring to the drawing and more particularly to Figs. l and 2 thereof, I and 2 represent re- ;5 spectively the two mainmembers constituting the jar. The member I is designated as the inner or containing member, and the member 2 is designated as the outer or base member.

The inner or containing member I is a thin- 50 walled 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 bottom wall 55 of the containing member is indicated at 3, and

(ci. ais-12) tion 4 is an outward projecting integral annular 5 flange 6.

'I'he outer or base member 2 is so related to the containing memberl as to permit the said con- -taining member to be assembled vertically downward with respect thereto. The base member has 10 a peripheral annular portion 1 which surrounds the entire lowerportion of the containing member and is spaced outward therefrom. The said annular portion is threaded adjacent its top edge, preferably externally, as indicated at 8. 15 'I'he outer or base member 2 preferably has a bottom wall 9, and this bottom wallmay engage and support the inner member l although I do not so limit myself. As shown in Fig. 2 the bottom wall 9 of the base member has a central boss Il) which 20 enters a depression-in the bottom wall of the containing member. This boss serves to support the containing member and to assist in holding it in a central position.

There is provided a retaining ring II, struc- 25 turally separate from the containing member and from the base member. This ring is threaded to engage the threads on the base member at 8, and it has an inward projecting ange I2 which overlies and engages the ange 6 on the containing 30l member to prevent relative upward movement of the said member. 'I'he said ilange I2 engages or substantially engages a peripheral portion of the containing member and it thus cooperates with the boss I0 to hold the containing member in 35 i central position.

Preferably the bottom of the flange I2 and the top of the ange 6 are provided with interengaging serrations as indicated at I3 which serve to prevent relative rotative movement of the containing member. The serrations I3 are exaggerated in size for convenience of illustration.

In Fig. 3 I have shown an alternative embodiment of the invention. As shown in this ligure, la and 2 represent respectively the containing 45 member and the base member. The containing member is threaded for engagement with a threaded closure cap 5 and below the threads is an outward projecting integral annular flange t, this flange projecting considerably farther than the flange 6 shown in Fig. 2.

' The annular portion 'I of the b ase member 2i is of 'such diameter that it engages at the top with the bottom surface of the ange 6* on the containing member. Thus the containing member is supported'by means of the ilange I" and no engagement is necessary or desirable between the bottom walls ofthe containing member and the base member. Y

The annular portion 'le of the base member is externally threaded at I* and a. retaining ring I II is provided which 'engages the said threads. The retaining ring has an inward projecting nange I2n which overlies and engages the ange 6l l0 on the containing member. In order to prevent relative rotation of the containing member the vbottom of the flange 6* and the top oi.' the annular portion 1 oi the base member maybe serrated as indicated at I 3*. The serrations as shown are exaggerated in size for convenience of illustration.

With either of the described constructions the threaded retaining ring serves to positively connect the containing member with the base member, no dependence being placed on friction las in some of the constructions illustrated inmy said co-pending application Serial No. 18,031. 'Ihe containing member is normally entirely concealed, this sometimes being an advantage particularly when its color does not harmonize with the color selected for' the outer or base member. Theretaining ring provides a relatively broad band o! color which can be chosen to pleasingly harmonize with the colors of the base member and of the closure.

What I claimis:

1. The combination in a iar of the class described, of a thin-walled cup-shaped molded containing member externally threaded adjacent its 35 upper periphery for engagement with a closure of the cap type and having its interior diameter at the' top at least as large as is the interior diameter below the top, the said member having a thin outward projecting annular flange imme- ,40 diately below the thread, a molded base member having an annular portion which surrounds the containing member and which is threaded adjacent its upper edge, and a retaining ring structurally separate from the containing member and .45 from the base member and having threaded engagement with the upper threaded portion ofthe latter, the said ring having an inward projecting Y flange which overlies and engages the ilange on the containing member to prevent relative up- 50 ward movement ofthe said containing member,

2. 'I'he combination in a :lar oi' the class described,vof a thin-walled cup-shaped molded con- L taining member externally threaded adjacent its upperY periphery for engagement with a closure'.

member and directly engaging the bottom wall thereof, the said base member also having an annular portion which surrounds the containing member and which is threaded adjacent its upper edge, and a retaining ring structurally separate from the containing member and from the base finember and having threaded engagement with the threaded portion of the letter, the said ring having an inward projecting ange which4 overlies and engages the flange on the containing member to prevent relative upward movement oi a molded base' member having a boss on its bottom wall entering the recess' in the bottom wall of the containing member, the said base member also having an annular portion which surrounds the containing member and which is threaded adjacent its upper edge, and a retaining ring structurally separate from the contaning member and: from the base member and having threaded engagement with the threaded portion of the latter, the said ring having an inward projecting ange which overlies and engages the ilange on the containing member'to prevent relative upward movement of the said containing member.

4. 'I'he combination in a jar of the class described, of a thin-walled cup-shaped molded containing member externally threaded adiacent its upper periphery for engagement with a closure of the cap type and having its interior diameter at the top at least as large as is the ,interior diameter below the top, the said member having. a' thin outward projecting annular ilange immediately below the thread, a molded 4base member having an annular'portion which surrounds the containing member and which is externally 'threaded adjacent its upper edge, the

said annular portion of the base member directly engaging the bottom oi the ilange on the containing member, and a'retaining ring structurally separate from the containing member and from the bese member and internally threaded to engage the threaded portion of the latter, the said ring having an inward projecting ilangewhich overlies and engages the ilange on the containing member toprevent relative upward movement of the said Vcontaining member.
