""""" INVENTOR Patented Nov. 5, 1946 UNITED STATES 'PATENT OFFICE 1 2,410,585l n Y f f- LEAKPRQOF POWDER CASE Arthur S.Leitner`,lLos Angeles, Calif. Application March 3, 1945, Serial No. 580,863

3 Claims.

This invention rela-tes to a leakproof powder case.

One of the present drawbacks of ladies compacts is the tendency of the face powder contained in them to leak out between the hinged together members which are ordinarily used to form the casing of such articles, and soils the linings of expensive purses and handbags, as well as to damage o-r smear the contained articles.

It is one of the objects of this invention to overcome this defect by providing a leakproof powder case.

More specifically speaking it is an object of the invention to provide a toroidal ring made of compressible material, for example, sponge rubber, and so to position said ring within the article that it functions as a superior gasket to keep the powder from creeping out between juncture oi the closed lid with the remainder of the article.

Another object of the invention is to eccentrically mount the sealing ring in relation to the lid and body portion of the case (both of which are circular) so that a greater convenience of manufacture and more economical use of material will result.

Still another object is to provide an improved means for gripping the ring between the body portion of the casing and the closed lid whereby the gasket is pressure deformed in a superior manner to produce the desired sealing effect.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the drawing which illustrates what is at present deemed to be a preferred embodiment of the invention,

Fig. 1 is a diametrical midsection of the completedevice, showing the same in a closed condition.

Fig. 2 is a plan view showing the device in open position, the scale being smaller than that of Fig. 1.

Fig. 3 is an enlarged fragmentary section showing the relation of the free portion of the hinged lid to the adjacent part of the'body portion of the device and of the gasket. This view illustrates the novel, improved manner in which the gasket-compression groove in the lid is shaped so as more eiciently to deform only one side portion of the ring when the lid is completely closed.

Referring in detail to the drawing, the powdercase therein shown comprises two circular members 5 and 6 which are hinged together at one side by a conventional hinge 1, the lid section B having its free side portion furnished with a 'the body'member Said body member has a two-part flat area lI extending along the inner face of its marginal portion, the two parts of this flat area being separated by a semicircular l groove I2. The lid section likewise has a two-part flat marginal portion I3, the two parts of which are separated by a groove I4, this groove, however, being of less depth than the groove I2, the depth of said groove III being decreased, preferably by reason of it being flattened at I5 along its deepest portion, as shown.

The reason for providing the groove Ill with the liattened Strip I5 along its deepest portion is to cause the toroidal, compressible gasket, or sealing ring I6, permanently seated in the groove t2, to be compressed in such a manner as to form a more positive seal when the two casing members 5 and 6 are in the fully closed relation to each other.

The aforesaid grooves I2 and I4 are each of them (as to surface area) of the same size and shape, so that they will truly register with each l other when the article is in its closed condition.

but these grooves are so positioned as to avoid the necessity of widening the aforesaid flat surface portions II and I3 of the members 5 and S adjacent to the hinge 'l to provide additional stock for the formation of the latter. In order to accomplish this purpose each of said grooves be made out of a sheet material produced either from metal or from a metal substitute. Said members may be described as angularly dish shaped, being each shown in the drawing with a flat central portion I8 integrally surrounded by a flange I9 which is directed inwardly at a right angle, the already described grooved portions, as to their general directions, extending outwardly at a right angle in relation to said iianges. and being integral with them.

Leather. or leather like covers 20 are shown cemented to the exterior surface of the device, annular sheet metal inserts ZI and 22, angular in cross section, being secured to the outer faces of flanges I9 to .clamp in place the marginal portions 23 of said covers 20. These metal inserts 2l have their cuter portions curved as shown, in order to give a streamline appearance to the case as a whole. To the inner face of the upper flange I9 is secured an annular, angular bracket 24 for securing in place a circular mirror 25.

A powder puff 26 is shown overlying a layer of powder 21 to `-ll `the case inthe usual manner.

What is claimed is:

1. A leakprcof powder case comprising two hinged together members having marginal portions with at areas extending around them adapted to be brought into mated contact to close the case, one of said members having along .registering Ywith each other when the case is closed, and a; toroidal ring having one of its side portions sealed permanently in said semicircular groove and having its opposite side portion when uncompressed projecting above the first recited groove and deformable suciently to form a positive seal when said two members are swung completely together.

2. The subject matter of claim 1, and said groove which is of lesser depth having its deepest portion flattened.

3. In a leakproof powder case, two circular members having each a peripheral edge portion connected to that of the other by a hinge, said members having annular marginal face portions which abut when the device is closed', there v being in each of said marginal portions a groove which matches with that of the other, each of said groovesfbeing eccentrically positioned in relation to said circular members, so as to be offset ARTHUR S.
