POWDER DISPENSER.

Application filed July 11, 1924, Serial No. 725,489. Renewed September 29, 1925.

This invention relates to receptacles in general and it pertains more particularly to the species used for the distribution of powder.

One object of the invention is to produce a nonrefillable article. of the kind described,

adapted to be removably inserted into an low priced materials, so as to permit the same to be discarded, when emptied of its contents.

Still another object consists in. producing an article of the class set forth,wherein means embodied in a relatively unyielding internal rim or ledge render the later -sufliciently resilient and pliable to conform, to the coacting surface of a closure member, and make a tight joint therewith, dispensing as well with seats of soft texture intermediate the before named ledge and member.

A still further object resides in providing an article of the type referred to, comprising but few plain parts, exclusively of metal;

readily produced,"--'char ed and assembled bythe least expensive la or; besides reliable and convenient in operation.

Other objects and advantages of the invention will become apparent as the specification proceeds.

With the aforesaid objectsin view, the inventon consists of the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the s'ubjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

Generally described, the article forming the subject of the present invention, consists of a pair of comparatively shallow andlow rimmed saucer-like elements, fittin in converted and inverted relation one inside of the other so as to constitute a powder box or receptacle. The lower element is formed, around its peripheral bottom corners, with 'the thereto pertaining arrows;

an inwardly turned annular rabbet into which is crimped the free, depending edge of the rim of the upper element, in order to prevent these elements from being disassociated. The to of the upper element is provided with a attened and depressed portion having a central opening through which the powder is discharged. A gradually dished.

field reaches intermediate the circumferences of the depressed portion and the rim of the top element. At a specified distance from the inner edge of the discharge opening are formed in the depressed portion, a series of arcuate incisions or closed slits which serve to weaken the aforesaid edge and make it pliable or flexible. Coacting with the underside of the before mentioned edge of the discharge opening, is a closure member which is held up against the latter by means of a spring havin differential resiliency.

-Means are provide to limit the amount that the closure member may be depressed to admit of a certain outflow of powder from the receptacle, and also to make it more difficult or inconvenient to refill through the discharge opening. The power of the spring is sufficient to urge the receptacle elements apart andthus render them, as well as the closure member, inoperative, if an attempt be made to pry open the crimped joint intermediate the said elements.

" The advantages of the invention as here outlined are best realized when all of its features 'and instrumentalities are combined in the one and same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, upon becoming conversant with the details thereof, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.

In the said drawing Figure I- is a full top plan view of this improved powder distributor;

Fig. II is a section on the line IIII of Fig. I, looking upwardly in the direction of Fig. III is also a top plan view of the article in question, from which some parts are omitted; and

' rim is of a size to take over the low rim with a tight fit, on the order of a cover.

Below its marginal annulus the said upper shell 17, is provlded in the middle thereof, with an approximately flat, depressed portion 23, the centre of which has cut therein an opening 25. Intermediate the inner and outer circumferences of the annulus 19 and the said depressed portion, respectively, extends a. sloping or funnel-shaped field 27. For the purpose of making theborder of the opening 25 yielding or flexible, so that 1t will accommodate itself tightly to the upper face of a closure "member 29, the said portion is weakened transversely. This is conveniently accomplished by embodying on the flat border or ledge 23, a series of incisions or indentations 31, in proximity to the said opening 25. By preference, these incisions may consist of a plurality of arcuate slits, spaced apart both endwise and laterally, being as shown disposed in staggered arrangement with relation to one another. The slits are indicated by single lines in Fig. I, but in the enlarged disclosure aiforded by Fig. IV, which is taken across two of the aforesaid slits or'incisions, it clearly appears that the metal between them, is forced downwardly or ofi'set relatively to the plane it was originally situated in, still without severing the same from the ledge. Subsequently to pressing the bridges or connecting strips 33 intermediate the before mentioned slits back into the normally flat position, as indicated in Fig. II, the opening 25is punched out, so as not to wrinkle or distort the interior edge thereof. While the treatment thus given to the flat edge or border 23, renders the same quite pliable, it does not permit any of the powder to leak through the incisions, in view of the fact that their adjacent sides are ultimately in close contact with one another.

The hereinbefore named closure 29, is preferably composed of a slightly crowned or convex disc like plate surrounded by a downwardly curved peripheral border or edge 35. The edge last referred to, is held in abutting relation to the underside of the upper shells flexible inner margin 23, by the outer ends of shorter and stifl'er tongues 37 radiating from the central part of an astralis depressed in order to discharge from the box or receptacle some of the powder contained therein, out through the opening 25 in the upper shell 17, for distribution over the ledge 23 and the sloping field 27 where it can be mopped up by a. powder-puff (not shown), the longer tongues 41 which are the lowermost as well, flex first, until an ear 43 touches the inside of the bottom 13. If the downward pressure is continued, the higher located tongues 37 will also bend till the underside of the closure 29 strikes against another ear 45. Both of these ears, as seen to best advantage in Fig. III, are stamped out of the central part of the said spring 39, and bent therefrom in opposite directions. The said ears 43 and 45 constitute stops for limiting the opening movement of the closure member relatively to the inner marginal ledge 23. The construction of the spring 39 is such that it not only holds up the closure, but guides the latter as well.

The means for preventing the container and cover elements 11 and 17 respectively, from bein disassociated, comprise as indicated at t e lower part of Fig. II and also in Fig. III, a rabbet 47 of a certain width, formed with the peripheral corners of the bottom 13 and the rim 15, which rabbet as shown, is turned inwardly of the shell 11. The free or depending edge of the rim 21 pertaining to the cover shell 17 is, subsequently tothe last named cover having been placed over its companion shell 11, crimped as represented at 49, into the said rabbet 47 from the underside. The interstice intervening between the inner circumferences of the rabbet and the crimped edge 49, may, as represented at 51, be filled with a suitable sealing material, in order to divulge to the purchaser of the article if the same has been tampered with.

The spring 39 possesses ample strength to urge the shells 11 and 17 away one from the other, prior to the edge 49 being crimped over the corner of the rabbet 47, so that if an attempt is made to turn over outwardly the said edge, for the purpose of recharging the bottom shell, the rims 15 and 21, of the latter and the cover shell, respectively, cannot remain in tight association. Nor will, under the conditions mentioned, the closure 29 engage the ledge 23 with sufficient pressure to preclude leakage of powder therebetwecn, and therefore the article is practically inoperative unless the shells 11 and 17 are intersealed. The average user of an article of this kind, does not possess appropriate implements for neatly taking apart and putting together the ele- I ments spoken of. Even a fairly good meient.

chanic could only do this a few times before the edge 49 would crumble away under repeated bendings. Attempts to re-fill the assembled receptacle through its discharge opening, would be too tedious and inconven- Truly the space between the border 35 of the depressed closure and the overlying inner margin 23, is large enough to afford an outflow of powder when the box lodged within a surrounding vanity case, is shaken or agitated. But this space is entirely too constricted to permit entering the powder therethrough, counterwise to the air passing out of the receptacle which it has to replace. Matters would only be Q made worse by trying to tap or knock the tity of powder therein, brings up box with the fingers or against some hard object, with a charge of powder deposited on top of the closure, as this could only serve to stir up and cause the powder to fly about.

From the foregoing, it will be obvious that a practically non-refillable, inexpensive container has been devised, out of which the required amount of powder can be dispensed at will. The mere act of pressing down upon the closure thereof with a superposed powder-pufl', while giving the container and its encompassing casing, more or less of an accentuated shake, depending upon the quanenough of the latter for a facial applicatlon. Whenever the inter-sealed container shells are emptied of their contents, they are discarded and a set of new and full ones is substituted in their stead. When the article is to be filled from the beginning, the powder is poured into the lower shell 11 wherein the spring 39 has previously been inserted. Subsequently, the closure 29 is laid upon the upper tongues 37 of the spring, after which the cover shell 11 is placed over the foregoing assemblage, and finally sealed to prevent disassociation as hereinbefore described.

hile a certain preferred embodiment of this device has been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made, without departing from the scope of the invention as defined by the appended claims.

Having described my invention what I desire to secure by Letters Patent and claim, is v 1. An article of the type specified, including a pair "of coacting rimmed container elements, one of said elements being provided with a discharge opening in its top face, depressed below the rim of the other element, a spring urged closure coacting with the edge of said opening, and means for tightly securing the said elements one to the other to prevent disassociation and movement therebetween.
