Powder puffs are already 4known which are combined with a powder container from which powder is dispensed to the pul according to the quantity oi?k powder needed by the user at every moment. But the known devices of' this type areobjectionable because they are complicated, difcult to handle, and not easily controllable.

This invention has for its object the avoidance of the aforesaid drawbacks and it consists in the provision of a powder sprayer made of a box havingr dispensing or delivery meansassociated with the box so that the powder contained in the box can be VeasilyA and accurately delivered from the box at every moment.

This sprayer is intended primarily for use lin combination with a ypowder puff, as known per se, and will be describedr in detail in the following specication as combined with a powder pun'. But, of course, the sprayercan be used alone or in any other combination without departing from the principles of the invention.

Itwill be seen, therefore, that there Varewfour comparte ments 2| within the box communicating through the four holes 4 with the cavity I9 and so 4with the small oriceI 0a.?

The box thus constructedfmaybe'closed-by a cover which'incorporates the means for projecting the powdera This cover is seen in Figures `1 and '7, and comprises two ririgs' and 8,'-the ringV 8 being an-external ring and the ring-6 internal.-

The external `ring Stisformedwith an inward ange 8b and the internal ring Sis :formed with an outward flange 6d., Thetwo rings` arev screw threaded at Il, so .that the flangey of theA ring `6 can be .screwed into the cylindricalA par-t! of. the

ring :8. First,. however;l asexible'zf and fela'sticl membrane .'I. -of Y.suitable :material such 'as rubber:

is inserted in the ring 8 and so that the rim of such membrane lies against its flange Ilb of the ring 8, whereupon the ring 6 is screwed in tightly so that the said rim is firmly clamped between the two flanges 6d and 8b as seen in Figure l. For obtaining the best hermetic tightness, the flange 6d of the ring 6 may be formed with a projecting rib Iib which indents the rubber when the ring s is screwed in as above described. This assembly constitutes the cover of the box and is attachable to the latter by prolonging the screw threaded part I1 of the ring 8 beyond the flange 6d of the ring 6 so that such prolongation can be screwed on to a screw threaded upper end portion of the box I. Between the cover and the four compartments 2I of the box there is interposed a thin and slightly flexible plate or diaphragm made of any appropriate material, such as, for example, one of the so-called plastics. This diaphragm 5 rests upon the upper edges of the partitions 2 and upon the upper surface of the boss 3 and fits loosely into the space bounded by the upper cylindrical part I5 of the box I. The diaphragm 5 is prevented from rising by the lower edge Iic of the ring 6. However, the construction is such that owing to the flexibility of the diaphragm 5 and the slight play that it can have between the upper edges of the partitions 2 and the edge 6c, it is possible for air to pass around the edge 5a, Fig. 8, of the diaphragm 5 from the compartments 2I into the interior 22 of the cover and inversely. The space is insufficient, however, for permitting the passage of grains of powder out of the compartments 2l.

The diaphragm 5 plays an important part in this construction and arrangement which is not obvious at rst sight. It serves two purposes:

First, it prevents the air pressure obtained by pressing upon the membrane I from causing an intense turbulence of the powder in the compartments 2|, which would result in powder being carried into the upper part of the cover Yin the neighbourhood of the membrane 1 so that a very small part of the powder would be delivered through theY holes 4 to the orice Illa. Second, it regularizes or modifies the pressure in the compartments 2l when the membrane 1 is sharply or irregularly depressed. By this means, a regular or uniform jet of air and powder emerges from the orice IllEL without carrying with it clots of powder. y

The puff I2 is xed against the bottom of the box l and in the example illustrated, as will be understood from Figures 1 and 4, this fixing is obtained by the head flange of the ferrule I0 pressing against the bottom of the box a tubular annulus II having a peripheral split or slot IIa in which is inserted the edge of the central hole in the puff I2. By screwing in the ferrule I0, the tubular annulus II is clamped so that the said annulus clips the puff I2 in the slot I Ia.

Preferably a circular recess or seating 23, Figure l, is formed in the bottom Ib of the box I for the reception and centering of the annulus II. The operation of the pui device is as follows: After removing the cover, seen separately in Figure '7, and the diaphragm 5 from the box I, the compartments 2I of the box I are charged with powder and the cover is then screwed on. When it is desired to use the device, the pui I2 is applied lightly to the face and at the same time pressure is applied, by the forenger for example, once or several times upon the membrane 1. The air contained in the space beneath the membrane 1 is thus forced into the compartments 2| and carries powder with it through the openings 4, into the cavity I9 and out through the small orifice Illa. The air and the powder are guided by the exterior of the cone 9 towards the orifice Illa. A light jet of powder then issues into that part of the puff situated in the neighbourhood of the orifice I0a and comes on to the skin beneath that part. By moving the puff on the face, the powder is distributed over the surface of the skin as when using an ordinary pui. The operation can be continued whilst applying several pressing actions against the membrane 1. When the powdering operation is finished. the puff I2 remains charged with only a minute quantity of powder so that there is practically none to leave the face or to fall upon objects or surfaces.

Instead of the flexible and elastic plane plate or diaphragm 5 it is possible to employ a disc 5, Figure 9, composed of a fabric screen of very line mesh encircled by a rigid ring or a ring of rubber 5b, or even a disc pierced with very ne holes close together. The essential thing is that the air must be able easily to pass through the disc or around its edge 5fi whilst the powder, practically, cannot so pass.

What I claim is:

l. A powder sprayer comprising a box having on its bottom a projection formed with an axial bore, presenting a small exit orifice, radial partitions in said box, said partitions having openings therebetween near the centre of the box giving communication with the said axial bore, an axial inverted cone disposed in said box so that its base limits the openings between the partitions whilst its apex penetrates the said bore into the neighbourhood of the said exit orifice, and air forcing means xedly mounted on the box and adapted for forcing air from the box through said openings and into said bore.
