United States Patent Chadfield et al.

[ Mar. 18, 1975 DOUBLE-WALL JAR [73] Assignee: Federal Package Corporation,

Minneapolis, Minn.

Primary Examiner-Herbert F. Rose Attorney, Agent, or Firm-Francis J. Bouda [57] ABSTRACT A jar, generally made of light weight material such as polypropylene or medium impact styrene, and designed particularly for vending cosmetic materials such as facial cream, which jar is a two-part container (exclusive of cover), each part having a relatively thin wall, designed, when assembled, to provide an airspace between the walls of the two parts, but particularly with the interlocking and interconnecting portions of said parts concentrated in an upper zone near the rims of wall parts and adjacent the threaded portion holding the cover, so that all forces of antirotation and anti-part-separation are located in the same area adjacent the threaded portion.

14 Claims, 5 Drawing Figures DOUBLE-WALL JAR BACKGROUND OF THE INVENTION also because ofthe resistance to the chemical action of the cosmetics.

More recently such jars have been made out of plastic materials, and even still more recently such jars have been developed in one or more parts, not only to give the general feeling and physical appearance of the milk-glass or opal-glass jars, but also to provide an insu- Iating inner space between the contents within the jar and the outer wall of the jar.

Construction of such parts in the past has provided for interlocking means so that the two portions of the container do not rotate relative to each other and do not separate axially after once being combined. In the past, such construction has been complicated and, in many cases, ineffective because of the tendency of the two parts of the double wall jar to separate when the cover is applied or removed from the jar.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a double wall jar, for cosmetics or the like, which is easily asssembled, which is absolutely secure against separation of the two parts of the jar, and which concentrates the interlocking portions of the members in an upper portion of the side walls near the cap-receiving threaded portion so that all forces which may tend to separte the two parts ofthe jar are concentrated closely in the area adjacent the interlocking portions.

DETAILED DESCRIPTION For the purpose of illustrating the invention there are shown in the accompanying drawings forms thereof which are at present preferred, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and that the invention is not limited to the pre cise arrangements and organizations of the instrumentalities as herein shown and described.

In the drawings, wherein like reference characters indicate like parts;

FIG. 1 represents a fragmentary, cross-sectional view of the jar of the present invention, with the two parts interlocked and with the cap in position thereon.

FIG. 2 represents a fragmentary, cross-sectional view of the outer part of the jar of the present invention, showing particularly the toothed connecting portion at the upper portion of the inner wall of said part.

FIG. 3 represents a fragmentary, cross-sectional view of the inner part of the two-wall jar of the present invention. illustrating particularly the toothed interconnecting members on the outer wall near the upper edge and adjacent the threaded portion.

FIG. 4 represents a horizontal, cross-sectional view taken along line 4-4 of FIG. 3.

FIG. 5 represents a greatly enlarged cross-sectional view of the interconnecting portions of the upper edges of the said parts of the two-wall jar ofthe present invention, taken in the area generally illustrated at 5 in FIG. 1.

In the illustration of FIG. 1, the two-wall jar is shown in assembled position with the cover or cap 11 in place thereon. The jar 10 consists of the outer portion 12 and the inner portion 13. The inner member is constructed, preferably, of polypropylene because of its inert characteristics to the components of cosmetic substances, whereas the outer member is constructed preferably of medium impact styrene because it affords a wider range of moulding characteristics and an opportunity to decorate the external surface of the outer member during the moulding operation. Needless to say, the outer member may be polypropylene and the inner styrene, or both may be of thesame material, and of course, the material of either member may be other than styrene or polypropylene. The utilization of polypropylene and medium impact styrene provide not only strength and shock resistance but also flexibility for the snap-interconnection of the two parts, as hereinafter described. 1

As is evident in FIG. 1, the dimensions of the inner and outer members are such that a hollow air chamber is created between the two members, not only providing for better aesthetic arrangement of the two members, and of the total jar, but also providing an insulating air space between the two walls of the two portions, if such is desirable. I

At the upper edge 15 of the inner member 13, there is a threaded rib 16 constructed and arranged to receive the internally threaded portion ofthe cap 11. The shoulder 17 provides an abutment, at its underside 18, against which the top lip or edge 19 of the inner member 12 can stop when in interlocking relationship, as shown in FIGS. 1 and 5.

Directly beneath the shoulder 17 on the member 13 are disposed one or more sections of toothed or notched portions 20, which may be in the shape of quadrants of gears. These quadrants or gears or toothed portions are arranged with the teeth extending in an axial direction, and preferably two of such quadrants are disposed diametrically opposite each other, as shown in FIG. 4, for better ease of moulding or forming the serrations in the plastic body of the member 13.

In close proximity to the teeth 20 is a rib 21 which extends outwardly from the outer surface ofthe body portion of the member 13, which provides an integrally moulded snapring for interlocking engagement with the mating portion on the outer body member 12.

The outer body portion 12 has, adjacent its upper edge 19, a circumferential ring of teeth 22 which are designed, constructed and arranged to mate with the teeth 20 on the other body portion, as shown particularly in FIGS. 1 and 5. Directly adjacent the teeth 22 a circumferential rib 23 is moulded into the inner wall of the outer member 12 and which projects radially inwardly from the inner wall, as shown particularly in FIGS. 2 and 5. This rib 23 is designed, constructed and arranged to mate with the groove 24 formed in the outer surface of the inner member 13, between the rib 21 and the teeth 20.

Because of the inherently flexible nature of the material from which the cup-shaped members 12 and 13 are made, the ribs 21 and 23 and the groove 24 are nicely and appropriately dimensioned so that the inner cupmember 13 will nest within the outer cup member 12, with the teeth 20 in interlocking alignment with opposed teeth 22, and with the rib 23, disposed between the rib 24 and the shoulder 17, extending into the groove 24, thus to interlock axially the two cup members and to prevent axial displacement thereof.

While such members are held in axial alignment by the ribs, grooves and shoulders as described above, the teeth are in interlocking disposition with the teeth 22, preventing relative rotary movement between the two body members.

It can be clearly seen that with the teeth 20 and the teeth 22 directly beneath the shoulder 17, all the interlocking forces are concentrated directly beneath and adjacent the threaded portion on the inner jar member and the cap, and in the area where the forces tending to separate the two body members (when the cap is screwed on or off) are applied. Thus there is the maximum potential to hold the two body members together and to prevent separation thereof.

It is to be understood, however, that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiments be considered in all respects as illustrative and therefore not restrictive, reference being made to the appended Claims rather than to the foregoing description to indicate the scope of the invention.
