Application October 11, 1954, Serial No. 461,438

6 Claims. (Ci. 132-83) This invention relates to cosmetic boxes, and more particularly to a compact suitable for carrying loose cosmetic powders.

The cosmetic industry has long been faced with the diilicult task of developing an inexpensive box capable of retaining loose powders. The problem of constructing a compact of this character was a particularly difficult one, for substantially perfect seals are necessary between the cover and case to prevent leaking of the powder through the seams of the box. Heretofore the industry has only partially overcome the numerous diiculties by fabricating from metal compacts to hold loose powder. The metal edges of the compact, with great care, could be shaped to form an adequate seal to retain the powder but this necessarily created considerable expense on the part of the manufacturer, and although the operability of the seal between the cover and case was adequate, it did leave much room for improvement.

The use of metal in the construction of compacts gave rise to other problems. For example, when a tongue and groove were formed in the cover and case to provide a seal, powder would collect in the groove. Lacking flexibility, the groove could not expand to receive the tongue when powder partially filled it.

Ultimately, the cosmetic industry was forced to provide loose powder substitutes. Constant spilling of the loose powder from the relatively expensive metal compacts virtually gave birth to the cake powder industry. The inability of the cake powder to spill permitted the use of highly decorative and relatively inexpensive polystyrene in the manufacture of compacts. The cake powder did not require a highly eiiicient seal and, therefore, relatively rigid polystyrene provided the ideal substance to permit inexpensive fabrication of the cake powder compact.

The primary object of this invention is to greatly reduce the cost of constructing a loose powder cosmetic box.

Another object of this invention is to provide a highly eilicient plastic seal between the cover and case of a polystyrene compact which prevents seeping of loose powder from the interior of the case. y

To accomplish these and other objects, we provide as one important feature of this invention avpolyethylene gasket on the rim of a polystyrene cosmetic case.

Still another important feature of this invention is the provision of a line seal between a relatively rigid plastic bezel carried by the cover of the compact and the polyethylene gasket carried on the rim of the case.

Still ano-ther feature of this invention is the provision of a tongue and groove connection between the rigid case and cover of the compact in addition to the seal provided by the bezel and gasket.

These and other objects and features of this invention will be better understood and appreciated from the following detailed description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawing in which:

Patented Mar. 6, 1956 ICC Fig. `1 is a plan view of a compact constructed in accordance with this invention,

Fig. 2 is an elevation view partially in section of the compact illustrated in Fig. 1,

Fig. 3 is an exploded view in section taken along sight lines 4-4 of Fig. l, and

Fig. 4 is a view in section similar to Fig. 3 showing the various elements of the compact in assembled position.

Proceeding now to a detailed description of the invention, an inspection of the drawing reveals that the elements of the compact are organized within a case 10 and a cover 30. The case and cover may readily be molded from polystyrene or other rigid plastic material and may be ornamented if desired.

The case 10 is provided with va relatively thin bottom wall 12 which cooperates with a cylindrical side wall 14 to form a shallow cavity for receiving loose cosmetic powder. The wall 14 intermediate its upper and lower portions is provided with an annular seat 16 in which is formed an annular groove 18. The upper terminal portion of the wall has integrally molded with it a tongue 20 which cooperates with a slot 32 in the cover sectio-n.

Seated on the surface 16 of the wall 14 is a relatively flexible ring or gasket 24 preferably molded from polyethylene. The gasket 24 has integrally formed therewith a tongue 26 which is received by the slot 18 in the annular seat 16. The gasket may be retained in position by pressing the tongue in the slot. The flexible tongue of polyethylene will by pressing, form a most satisfactory seal with the case. Not only does this eliminate the need of cernenting the gasket to the wall but further permits the removal of the gasket when desired. The advantages derived from being able to remove the gasket will be made clear in the description that follows.

The gasket 24 is of a size to extend over thepradially inner edge of the wall 14 of the case. A cloth compact sifter 22 which rests on top of the loose powder within the case and is of a diameter substantially equal to the diameter of the cavity is retained in position by the slight overhang of the gasket. The cooperation of the gasket with the sifter in this manner insures against slipping of the sfter and, therefore, prevents spilling of the powder when the cover is open. In addition, although the sifter is retained in position by the gasket, to refill the compact it is only necessary to remove the gasket from the seat 16 which permits withdrawal of the sifter. After the case has been refilled, merely placing the sifter above the powder and replacing the gasket on its seat insures against spilling of the compact contents.

Proceeding with the description of the gasket, it will be observed that a slot 28 is formed in the upper surface thereof adjacent its inner radial edge. The slot 28 cooperates with the tongue 36 of a bezel 34 forming part of the cover assembly to provide a line seal between the cover and case sections of the compact.

The annular bezel 34 molded of rigid plastic material, preferably polystyrene, performs a dual function in the compact. Most important, the rigid tongue 36 carried bynits lower face cooperates with the inner exible wall which defines the gasket groove to provide' a substantially and the peripheral portion of the mirror 46, respectively. To retain the bezel, disc, mirror, and cover in their assembled position, cement or other adhesive material may be employed. Once the cover section is assembled, no need will arise for dismantling these elements and, therefore, the use of adhesive does not limit the life or restrict the use of the compact.

Having described the cover and case sections of the compact it will be appreciated that the various elements which comprise the assembly with the exception of the mirror and the sifter readily may be formed by conventional injection molding machines. Both polystyrene and polyethylene are conveniently worked by such apparatus which provides an inexpensive means of fabricating the compact. Moreover, the polystyrene bezel and polyethylene gasket achieves a virtually perfect seal for the cavity carrying the loose powder, by means of the cooperating tongue 36 and groove 2S in the respective parts. A second tongue and groove 2t) and 32 formed in the case l and the cover 30 respectively constitute added protection against seepage of the contents of the compact through the seam of the box.

To secure the cover assembly to the case, a hinge generally designated by the numeral 52 is provided. A flange 54 integrally molded with the cover extends downwardly into a recess formed in the case, and is held in position by a pin 55 which passes through the flange and engages the walls of the recess. Across the diameter of the compact a latch 58 is provided t-o yieldably retain the cover to the case. The latch may be of any form, the details of which form no part of this invention. Obviously, the elements comprising the latch may be integrally molded with the cover and case sections, as illustrated.

Having thus described in great detail all of the components of the compact, the advantages derived therefrom will be fully appreciated. When closed, not only is a tongue and groove provided to seal the case and cover but a second seal of much greater effectiveness is provided between the bezel and gasket. The flexibility of the walls defining the groove in the gasket permit a negative clearance between the tongue and groove, thereby guaranteeing a positive seal between these elements. The difficulties which are encountered by powder partially filling the grooves of metal cases is entirely eliminated, for a slight pressure on the cover will cause the groove 23 to enlarge and receive the tongue 36, even though powder has partially filled it.

Another important advantage is achieved by employing the teachings of this invention. With the exception of the mirror and cloth sifter, the entire uni-t may be molded which greatly reduces the fabricating costs. Furthermore, the plastic compact invites the ornamentation so much desired by women.

In essence, this invention embodies an inexpensive and highly efficient compact particularly designed to hold loose powder. From an appreciation of the foregoing description numerous modifications of this invention will be readily apparent to one skilled in the art to which this invention pertains. Therefore, it is not intended that the scope of this invention be limited to the specifically described and illustrated embodiment, but only by the appended claims and their equivalents.
