BACKGROUND OF THE PRESENT INVENTION

1. Field of the Present Invention

The present invention is a molded plastic container with living hinges which has three compartments. It is useful as a makeup case.

2. Description of the Prior Art

It is known to form molded plastic containers having a variety of compartments, for example, as makeup or vanity cases. Two examples of recent patents showing hinged plastic cases are U.S. Pat. No. 4,518,092 and 4,589,429. In U.S. Pat. No.4,518,092 the molded container is provided with "living hinges". Such hinges are known in the art. In the injection molding of such containers or compacts the various co-acting elements such as the base unit and its associated cover may be molded as asingle unit to provide a hinge therebetween of the same plastic material. Such hinges, because of the unique properties of certain plastics such as polypropylene and styrene-butadiene block copolymer, are particularly advantageous since they becomestronger with use and do not break under bending failure due to flexing of the hinge during the life of the compact. Such hinges are known as "living hinges". Such a structure forms an essential part of the present container.

SUMMARY OF THE PRESENT INVENTION

The present invention is a molded plastic container having three compartments which comprises: a central compartment; a side compartment on each of two opposed sides of the central compartment; and a living hinge between each of said sidecompartments and the central compartment to allow for movement of the side compartments towards and away from one another in the act of closing and opening the container.

The present case is formed in one piece, thereby providing a structure which is more economical to manufacture. The container is a space saving, one-piece structure which closes neatly to a very compact size. In situations where makeupformulations are contained in both of the side compartments, in preferred embodiments, the case can be closed so as not to allow for cross-contamination of such materials.

DESCRIPTION OF THE DRAWINGS

The present invention will be more fully understood by reference to the Drawings which form a portion of the present specification wherein:

FIGS. 1 and 2 are perspective views of the container in its closed configuration;

FIG. 3 is perspective view showing the container in its open configuration; and

FIG. 4 is an overhead view of the open container illustrating removal of a portion of a preferred plastic protective film covering the central compartment of the container.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

FIGS. 1-3 illustrate the plastic container of the present invention having three compartments. It has a central compartment 11 and two side compartments 12a and 12b which are on opposite sides of the central compartment and are separatedtherefrom by living hinges 13a and 13b. It is clear that when side compartments 12a and 12b are moved towards one another so as to rotate about their respective living hinges 13a and 13b, the net result upon complete closing of the container is thestructure shown in FIGS. 1 annd 2 wherein compartment 12a forms one side of the closed case and compartment 12b the other.

The plastic container of the present invention can be used for a wide variety of purposes. However, for further illustrative purposes, it will be described in connection with use as a makeup case. As shown in FIGS. 3 and 4, the centralcompartment 11 can be used to hold an applicator 14 which can be held in place by appropriate peg means 15. Each of the side compartments 12a and 12b can hold either the same or similar makeup in appropriate pans 16. In a most preferred embodiment, inorder to avoid contamination of the makeup held in any of pans 16 when the case is closed, a transparent plastic sheet can be initially provided (as best seen in FIG. 4) overlying the case when in the open position with heat sealing of the plasticoccurring along edges 17a and 17b. Perforations 18a and 18b can be provided in the plastic sheet to allow for removal of the portion of the plastic film overlying the applicator 14 that is in the central compartment 11. When this occurs, the plasticwill only overlie the makeup pans 16 and will only be sealed at 17a and 17b, as shown in FIG. 3. This will allow the person to lift the plastic sheet to gain access to the makeup whereas the plastic will overlie the makeup when the makeup pan 16 is notbeing used. Since all makeup pans are covered by the plastic film when in the open position, the closure of the container will act to bring the plastic sheets into contact with one another isolating the respective makeup components in either sidecompartment 12a or side compartment 12b from one another. This will prevent cross-contamination of the makeup.

The foregoing has been provided for illustrative reasons only, the scope of protection that is sought is set forth in the claims which follow.
