The closure of that embodiment of the invention which is illustrated in Figures 1 to 5 inclusive; of the drawings, comprises a body section indicated in general by the numeral 1, which includes a substantially cyhndrical wall 2 and a top 3 preferably integral therewith, the wall 2 being provided with any suit-able means, such for example as stamped-in .lugs 4, for coaction with threads provided, as usual, upon the neckfi of the powder container, which is indicated and atransverse.slot 10 is formed at the opposite end of the said recess in the bottom wall thereof.: The top is further formed in the bottom wall of its recess, with powder discharge openings indicated by the numeral 11, whichmay be of any desired number and arranged in any desired manner.

The valve of ciit-ofl. plate of,the closure is indicated by the numeral 12 and the same comprises a substantially rectangular body portion 13 which is. of a width to fit snugly and yetslidably in the recess 8 between the opposite side walls thereof but of a length slightly less than-the length ofthe said rewhich, in one position of the member, regis ter with the openings '11 to permit of the end of the bod t closure,

' curved from so that the spring is normally discharge of powder and, in the other position of the closure member, are out of registration with the openings 11 so as to prevent the discharge of powder there: through. In order that the closure member may be shifted to the first mentioned position, a. finger piece is provided at one comprises a shan portion 15 which fits slidably in the extension 9 of the recess 8, and a down turned end portion 16 againstwhich the finger may be pressed for. the

urpose of shifting the said cut-ofi memer. In order to yieldably. hold the cutofi member shifted, to the position where it will close the openings' 11, a spring indicated in general by the numeral 17 15 provided. The spring 17 comprises a single spring leaf which is formed, intermediate its ends, with a longitudinal slot 18 into which projects a lug 19 which is struck up from a tongue 20 formed at that end of the plate 13 opposite the end at. which the finger iece shank 15 is located, the spring being m this manner supported upon the. said tongue 20 and the tongue being extendeddownwardly from the plane of the plate 13 so that the spring 17 extends transversely with relation to the said end of the plate.- The ends of the spring leaf are the plane of the intermediate portion f the leaf,as indicated by the numeral' al, and in assembling the cut-01f member 12 vwith the body member-1 of the the tongue 20 is inserted downwardly through the slot 10, the spring 17 is applied to the lug 19, and the plate 13- of the 'cut-ofl member is disposed within the recess 8, the curved ends 21 of the said spring bearing against the inner side of the wall 2 of the body member 1, as clearly shown in Figures 2 and 3 of the drawings, tensioned and due to its tendency to straighten, yieldably holds the plate 13 comprising the cutoff member shifted to the position shown in Figures 2 and 3, in which position the openings 14 in, the said plate are out of registration with the openings 11 in the top 3 of the body member 1'. In the use of the container and in dispensing powder therefrom, pressure is exerted against the end portion 16 of the finger piece to shift the cut-01f plate 13 against the tension off-he spring 17 and bring the openings 14 into registration with the openings 11. It will be understood, ofcourse, that immediately upon release of the finger piece 16, the spring 17 will act to shift the cut-off member 12 to closed position.v

The closure includes, in addition to the 'parts thus far described, a cap ember which is indicated by. the numeral 22, and member comprises a,top 23 having openings 24 therein, and a rim 25 whic member 13 thereof and .ings 11 its area so that fits about the upper portion of the body member, 1 of the closure and has its lower peripheral portion 26 overturned about an outstanding circumferential head 27 formed on the wall of the member 1. The rim 25 of the cap member 22 is formed with a slot 28 through which the shank portion 15 of the finger piece of the cut-oil member is slidably fitted, and it will be evident that with the parts assembled, the cap member 22 is fixed with relation'to the body member 1, so that the openings 24 in the cap member are in vertical alinement with the open"- in the bottom wall of the recess 8 in the body member 1. In other words, there can be no relative rotative displacement of the cap member 22 with respect to the body member 1; due to the fact that the shank portion 15 of the finger piece of the cut-ofi member extends through the extension 9 of the recess 8 in the body member and also through the slot 28 in the rimof the pap member. The plate 13 comprising the cut-ofi member 12 is preferably of such thickness and the recess 8 is of such depth that the upper side of the said plate will be flush with the upper side of the top 3 of the body member and, when the cap member is applied, the cut-off member is, of course, held against any displacement from the'recess.

It will be noted that the cut-off member or slide is positively sustained by the tops of the cap and body members throughout ossible buckling of the slide is prevented and, furthermore, the likelihood of powder finding its way to the slide and collecting thereon in excess quantitles and thereby tending to clog the action is overcome.

In order that powder may be prevented from sifting from the container in the transportation of the article, a thin circular disc 29 of glazed tissue paper is preferably arranged between the to 23 of the capmember and the top 3 o the body member, in assembling these parts, so as to effectually close the -openings in tlfe several parts through which the powder is to be eventually discharged, it being understood that this disc is to be pertorated by the purchaser, any suitable toilet ploy'ed for this purpose. Not only does the thin ape; disc '29 serve the purpose above state but it likewise serves to prevent'sifting of powder between the under surface of the top 23 of the cap member 22 and the upper side of the cut-off member12 which might otherwise accumulate and possibly cause sticking of the said cut-off member.

In Figures 6 to 9 inclusive of the drawings, is illustrated an embodiment of the invention which is, in many respects. sub stantiall the same as the embodiment above describe and in these figures, the numeral article being em- 30 indicates the body member of the closure comprising the circumferential wall 31 and top 32, but in this embodiment the rim 33 of the cap member 34 is tapered or flared in a downward direction, as is also the upper portion of the wall 31 and the cap member is forced into place upon the body member at the time of assemblage of the arts and thus 'frictionally permanently hel in place upon the body member. In this embodiment of the invention, the top 32 of the body member 30 is formed with a recess 35 in its upper side corresponding to the recess 8 of the previously described embodiment, and the cut-off member 36, which, as in the previous instance, comprises a substantially rectangular plate 37, is slidably ntted in this recess and is provided with openings 38 adapted, in the shaftlng adjustment ofthe plate 37, to be brought into and out of registration with similar openings 39 formed in the top 32 of the body member 30. The cut-01f member is, in this embodiment, provided with a finger piece comprising a shank 39' having a down turned 611(1'40, as in the previously described embodiment, and the shank works in an extension 41 of the recess 35 and through a slot 42 formed in the rim 33 of the cap member 34. The top 32 of the bod member is formed with a slot 43 correspom 1 ing to the slot 10 of the body member of the previously described embodiment and similarly located. In this embodiment of the invention, the cut-oil member 36 is of resilient metal and the same is provided at its end opposite the end from which the linger piece shank 39' extends, with a downwardly extending shank portion 44 provided at its opposite sides with oppositely extending spring fingers 45 preferably having their terminal portions rolled upon themselves as at 46, so as to ride smoothly against the inner surface of the wall 31" of the body members of the closure, the spring fin ers in this embodiment performing precisely the same function as the spring 17 in the previously described. embodiment, the shank portion 44 extending downwardl through the slot 43 in the top of the be y member and the spring fingers extending beneath the 4 said top. In this embodiment, the cap'memscribed comprising assembled body and cap 30, and serves the same ber 34 is formed'with openings 47 vertical- 7 1y aligned with.the openings 39 in-the top "32 of the body member 30, and likewise,

acircular iece 0'! thin, lazed a 48 1s arranged between the "50 of tliie ca member 34 and the top of the body member urpose as the corresponding element29 o the first described 1* nbodiment.
