keeping it in the" proper "portion of the receptacle and keeping it from spilling-andatthe same time allowing it to come for-thandbe extracted when needed 'fbhusef Such-devices are commonly termedsifters and the'present invention contemplates a semi-rigid more or-less elastic device which' will normally snugly fit thepowder cavity 'and* is" provided with a foraminous section through which "the powder maybe extracted.

One form the invention maytake is shown in the accompanying drawinginfwhich Figure 1 is a top plan view of onetype of compact open' and provided with a sifter ofl the present invention. Fig. I2 is a; longitudinal verticalsection on the line'2'---2 ,oilFigQl. Fig.' 3,.is '"a' transverse vertical section' on the. line 33of, Fig. 1' the covering ofthe compact being shown closed and a. powder padb'eingshownin place. Fig. 4, is a plan view of a sifter removed from the compact.

The drawing illustrates'oneiform of compact comprisinga body 10 and'al cover 11 hinged thereto at 12. In the body 10 .is'a'cavity l3vfor. receiving loose pow.der.. As shown in, Fig. 1 the cavity may be more or less rectangular in plan and havingcurved corners. The body. 10 ofithe compact is illustrated astapered in thickness as shown in Fig. '2' and-y=correspondingly the powder cavity 13 is shown tapered beinggshallowerat the lower :end; 1 1',

The form of the compact and the powdercavity forms no part of the present invention which may be incorporated in a compact of any suitable form. As is well known in the art of the powder cavity may be circular or of other desirable shape and the depth of the powder cavity may be uniformor may vary in any way desired. The sitter will be-formed or adapted to corresponds with the shape of the powder cavity.

In the drawing a sitter is shown adapted to fit into the powder cavity. Thesifter illustrated comprises an outer coating of pile fabric such as velvet or the like 14 which may be of any suitable color to match or correspond with the compact or the powder used. The velvet 14 is mounted on a backing of stiffening buckram 15. The velvet will preferably be attached to the buckram throughout its entire surface with glue sizing or other suitable material. Compound sheets made up of layers of buckram and velvet may be formed in dies or the like and may be severed or cut by any suitable means either before, after or iniipli'batiain July 12, 1934 surfing-. 234; so

The pile of the velvet engaging the walls of the powder chamber "1 3 maybe'sl-ightly crushed'and in any eventj'forms' riction engagernenttherewith and tends h dthe'siiter in position overthe'powderhfi" Associated with the sitter .may be a powder pad 27 which may be somewhat larger than the opening 24 but small enough to fit within'the curved rim 23. As shown in Fig. 3 when the compact is closed the cover of the compact tends to hold-the pad 27 against the pile of the velvet of the face member'22 and thus .forms' a seal preventing egress of the powder. The combined velvet and buckram is rigid enough to normally hold its shape but it is flexible so that the sifter may be forced into the powder cavity 13 in such a way as to insure a more or less tight frictional engagementat the edges. The foraminous plate 25 is also preferably somewhat fiexible; The sifter thus gives when the pad is presed against it and powder may be extracted through the member 25 whether the powder chamber 13 is full or only partially filled.

Flexibility of the sitter has been indicated (possibly exaggerated) in Fig. 4 from which it will be seen that pressure by the pad or of the portion of its depending walls to more closely 'hug the adjacent walls'of the powder chamber 13.
