POWDER CONTAINER.

Application filed March 26, 1923- ScriaI No, 627,876.

To all whom it may concern:

Be it known that I, WVILLIAM E. nstr, a citizen of the United States, and resident of North Attleboro, in the county of Bristol and State of l\ Iassachusetts, have invented certain new and useful Improvements in Powder Containers, of which the following is a specification.

This invention relates to powder containers of the type employed for carrying about the person a supply of face powder or the like and is intended to provide a simple, convenient and reliable construction that lends itself readily to supply regulated quantities of the powder for use without waste and without danger of spilling.

Vanity cases of this type for carrying the powder in loose-form instead of in plaques have frequently been made with a perforated diaphragm laid over the supply of powder so as to sift through the perforations against a superimposed powder puff, but such a construction and arrangement results in allowing too large a supply of powder to sift through into the puff compartment so that the puff itself becomes overloaded with powder and oftentimes the pufi' compartment contains a considerable excess of powder which is easily spilled out of the shallow puff compartment when the lid of the case is opened.

The present invention overcomes these troubles by providing the hollow casing or.

container with a closure or imperforate diaphragm mounted so as to confine the powder within the powder compartment, provision being made by a valve perforation in the side of the casing to eject or discharge the powder upon the pad or puff at will and in such quantities only as the user desires. A further feature of the invention consists in the combination with the lateral perforated casing of a powder containing diaphragm of spring material so that the powder may be ejected through the orifice in the casing by pressure against the diaphragm as well as by merely shaking the box to deliver the powder on the puff held exposed to the orifice.

In the accompanying drawings I have illustrated a form of powder container or case suitable for carriage in aladys reticule or the like embodying the principles of this invention, in which:

Figure 1 is a side elevation of the complete case.

Figure 2 is a cross section on the plane 22 of Figure 1.

Figure 3 is a plan view of the open case with the powder-confining diaphragm partly brokenaway with a part of the side wall of the casingshown in section. I

Figure 4 is a cross sectional detail showing the side wall with the valve or gate in open lposition with relation to the discharge orice. r

In the practice of this invention, according to the form illustrated in the drawings, the main body portion of the casing comprises a bottom 1, to which is secured the annular peripheral or side wall 2 whose open top is covered by aremovable lid 3 attached in any suitable manner as by a hinge 4:.

Following the usual practice, a mirror 7 is secured to the inside face of the cover by means of a bezel 6. The side wall of the casing opposite the hinge is provided with a struck-out 11p 5 having spring engagement 9 formed with an outwardly projecting annular lip 10, the latter being very narrow so as to overhang the upper edge of the body member when placed inside of it. This diaphragm is preferably formed of spring metal normally bowed upward slightly to form an elastic or spring drum although this is not an essential feature of the present invention.

The side wall 2, is provided with a lateral perforation 11, between the bottom and the diaphragm 8, said diaphragm itself being imperforate. A valve or gate 13, in this case conforming to the interior curvature of the wall 2, is mounted so as to cover the discharge opening 11 and said gate is preferably provided with an aperture 15 intermediate of its ends arranged so as to be brought into register with the aperture 11 when the gate or valve 13 is shifted to discharge position. This valve may be mounted in any suitable manner, and I have here shown the side wall 2 provided with a short circumferential slot 12 through which is passed from the outside a small knob 1 L Whose inner end is secured to the valve so desired quantity of powder the diaphragm 8" is pressed into position inside the top of the casing, the valve 13 being at that time closed. A thin pad or puff may be placed on top of the diaphragm which forms a shallow tray for containing the padand the downwardly projecting mirror. When it is desired to apply the powder the lid is opened to removethe pad, the'valve is shifted to open position and the casing with its discharge orifice downward is; presented to the pad and the powder ejected through by shaking or by pressing the diaphragm 8 inward which serves to squirt. or eject a small quantity of powder onto the paid.

By this arrangement there is no loose powder collected in the pad or mirror-containing tray and only such quantity of' powder is appliedto the pad as the userl actually desires. Sift and waste is therefore avoided and the mirror is not obscured by becoming coated with powder as would be the case if the diaphragm itself were perforated to allow the powder to pass into the puff compartment.

lVhat I claim is:

1. A powder container embracing a hollow casing comprising a bottom' and a circumferential side wall, a lid engaged with said side wall to close the casing, an

upwardly arched diaphragm of spring 'metal detachably inserted in the upper por- 1 mally closing said aperture, substantially as described.

2. A powder container embracing in its construction a. hollow casing comprising a bottom and a circumferential side wall, a lid for closing the top of said casing, an internal powder-expelling diaphragm of spring metal mounted inside the casing to cover and retain the powder therein when the lid is open, the circumferential wall being perforated for the expulsion of powder, and an arcuate slidemo-unted inside the circumferential wall and movable from the outside to uncover the powder-expelling perforation to allow the escape of powder from the diaphragm when the diaphragm is compressed toward the bottom of the casing, substantially as described.

3. A. powder container embracing. in its construction a hollow casing comprising a bottom and a circul'nferential side wall, a lid normally closing the open top of said casing, an interiorly disposed spring-diaphragm mounted between the lid and-the bottom of the casing andacting, when com pressed toward the bottom, to expel powder through a discharge aperture in the side wall, and an arcuate slide valve mounted inside the side wall to cover and Lmcover said casing and slightly held in place by a radially projecting pin passed through a slot in the side wall to be accessible from the outside of the casing. y

In witness whereof, I have subscribed the above specification.
