s Claims. (011154-41) My invention relates .to the dispensing device art, and more particularly to a rouge orpowder applicator and av novel method of assembling it.

The rouge applicator of my present invention is an improvement on that disclosed in -my earlier application, Serial No. 416,326, led October 24, 1941, which has matured into Patent No. 2,365,921 of December 26, 1944. The method of assembly of my present invention is entirely novel, so far as I am aware.

A vchief object of my invention is to provide a dispensing device which will largely appear to be made of opaque material, but which is provided with a transparent window through which the contents may be viewed. I prefer to accomplish' this by providing an inner transparent member adapted to contain a material to be dispensed,

" such as cosmetic rouge or powder, and an outer retaining ring of opaque material adapted to hold ,l on'the inner member a sheet of dispensing fabric,

the opaque ring effectively concealing the edges of the fabric sheet and all but the bottom of the inner member. i,

A second chief object of my invention is to profvide a novel method vof assembling such a dispensing device which is simple to Icarry out and which provides a substantially improved product.

Other objects and advantages of my invention will be apparent from vthe following s'peication w and the drawing, which, are for the purpose of' illustration only, and in which: A, Fig. 1 is a diagrammaticview illustrating one step inthe assembly of the top element of my invention.

Fig. 11 is a bottom' view of the device illustrated VinV Fig. 7.

As illustrated in Figs. -9 and io-of-thedrawiug, my finished product comprises adispensing member l and a removable cap'member yladapted 'ing a bottom I8 and an annular sidewall I9, the

bottom projecting outwardly past the side wall tol form an annularvange 20. The receptacle member I1 is formed of transparent material, such as a suitable plastic, and this is an important feature Aof the, invention as will be disclosed hereinaiter. The annular side wall I9. is provided at its upper end with a counterbored shoulder 2| which is annular in form and which supports a circular Washer element 22 having a central circular aperture 23. The receptacle member I1 is lled with cosmetic powder, rouge, or anyiother desired cosmetic material to be dispensed and indicated at 24.

Supported on the washer element 22 is an annular fabric-supporting element 25 which is preferably, but not necessarily, formed of a resilient material, such as sponge rubber, and which has a central aperture 26 registering with the aperture 23 in the washer element 22.. Covering the supporting element 25 and extending downwardly around the upper Yrim of the side wall I9 of the receptacle member I1 is a porous dispensing sheet 21 which serves to retain'the powder 24 in the.

receptacle member I1 and yet which is pervious enough to the powderto permit it to lterout o the receptacle through the sheet. The sheet 21 may be silken velour, or other velvet-likev fabric,

the pile of the'fa-bric being turned outward. I prefer a fabric having a rayon pile, since rayon iibers are peculiar in having what may-be termed a self-cleaning character, especiallywith re-` spect to contamination by oily substances. The' ber I1 is an important feature of the invention,`

as it eiectively hides the irregular lower edge 29 of the dispensing sheet 21. The ring element 30 is also provided with an annular base flange 3l which engagesthe annular flange 20 of the bottom I 8 and is of substantially thesame diameter.

As indicated above, the cap member I6 telescopes onto the ring element 3D'to engage the base flange 3| thereof the cap member Ibeingof slightly smaller external diameter than that of the flange 3l so that the flange may bef gripped readilyby the fingers to retain it while the cap member is slipped off. It is also to'be noted that when the cap member I6 is in its closed position, as.illusmorst of 'the thermo-plastics.

trated in Fig. 7, it presses down on the upper face 24 from .the receptacle member Vl1 when the de-` vice is being carried in a purse or pocket.

By forming the ring element 30 of an opaque material and forming the receptacle member I14 of a transparent material, the sijde wallV of thedis-zv pensing member I5, as shown in Fig. 10, will; be

upper end of the dispensing sheet 21. As soon as the bond between the inner surface 4l of the ring element 3!) and the lower edge 29 of the dispensing sheet 21 has fully set, the ring element with Ytheffoap member I6 enclosing. it,'as shown i'n Fig. 4. maybe withdrawn from the form 34 v r,without distortion or vdisarrangement of its parts.

.wholly opaque, but upon viewing the dispensing member from the bottom, as illustrated infFig. 1l,t

it will lappear to have a transparent windowr 32'; i

therein through which inspection may be made of the powder 24 by a prospective purchaser'or by-a user;V Y-

- In assembling my device Yin accordance with my v invention,l .the` first step is illustrated in Fig. l, i `.whichshows a cylindrical form 34 havingv a rounded-upper edge 35, the form being suitably secured towa base plate 3E.

A dispensing sheet 21 which isi circular in form as illustrated in Fig.

8; is placed on the top ofA the. cylindrical form 34 i pwith-the lpile. thereof rfacedupwardly. The ring element- 3051s then telescoped downwardly over the dispensing sheet 21 and the cylindrical form 34 Ainto; engagement with `thebase plate 35 to the position Villustrated` in Fig 2. Since theV dispens- 1 ing ysheet has a resilient pile, the lower edges of :fthe-sheet, will be somewhat crimped in, as illus-` trated' in Fig. 2, and the rounded corners 31 therelzof willlbebulged slightly outwardly.

As illustrated in Fig. 3, a template 39 having a circular yaperture lilltherein, which is of substantiallythe-same diameter as the diameter of the` rounded: `corner-31 of the dispensingA sheet.21, is" then .positioned substantially as shown in Fig. 3

so'thatv only the top of the dispensing sheet 21 yprojects through the aperture 40 of the template. .A fluid solvent is 'then applied to the upper face should be one whichv will tend to dissolve the plas- -ti'c' material of which the ring element 3B is' formed, and `the solvent should also be volatile and non-injurious to the fabric material of which the dispensing sheet 21 is made.- Thus, for eX- Vample,'if.the ring element'is made of a cellulose acetate, the solvent applied to the ldispensi-ng sheet-.21. may be a Vvolatile solvent such as '-acetone, lethylene glycol monomethyl ether, or a similar substance, which will rapidly penetrate throughthe dispensing sheet by albsorption but` which'will finally evaporate from the dispensing 'sheet-*without injuring it. Similarly, |carbon tetrachloride' may be used as a suitable solvent for The solvent penetrates ydownwardly to the lower edge 29 of the dispensing sheet 21 and wets the inner surface 4I rof the ring element 3i?, which is engaged. by

`the dispensing sheet, causing this portion of the inner surface of the ring element to become tacky and adhere to the dispensing sheet. Due to its i volatile nature, the solvent quickly dries, and the pensing sheet 21. l v

The template 39 is then removed, and the cap member IB is telescoped downwardly onto the ring element 30, as illustrated in Fig. 4, to'engage the V'base flange 3l of the ring element. The cap member l'thus forms a protective enclosure over vthe.

The .cup-shaped receptacle member l1 is then Vfilled withV powder 24, and the circular washer element 22, which may be of -cardboard or any other suitable material, is pressed downwardly into the' receptacle member against the counter- Ibored shoulder 2 lY thereof, las illustrated in Fig. 5.

Either :before or after the receptacle member `l='1=i'slled with powder as illustrated in Fig. 5, the/.fabric supporting. element. 25 is pressed into supporting. position asiillustratedY in Fig. 6 within theV dispensingsheet 21, thus completing the assembly of! the top element of the inventionillusv,tr-ated in Fig. 6. The bottom element of the inve'ntion is illustrated in Fig. 5 and comprisesthe receptaclememlber I1 having powder 24 therein and'fthewasher .element 22` secured therein. as shown.. v Y

The upper peripheral edge 42 of the receptacle member I1 is then lightly coated with a solvent adapted to soften and tending to dissolve the edge,."and which may be the same solvent previously described; if the .receptacle member is fform'ed of cellulose acetate orasimilar substance. When. the .peripheral edge 42 is softened by the solventsuiciently tobecome tacky, the receptacle, member H is pressed into the. .ring element 3554 tothe position illustrated in Fig. '1, which com- .lpletes the assembly ,of the device. The solvent appliedtothe upperV peripheral edge 42. offthe tacky plastic in contact with the lower inner edge ofV the dispensing sheet 2,1,v to form a. secure bond of the dispensing', sheet 21 which projects through'vv -the aperture 40 yof the template 39, by hand brushing-,bya roller, or otherwise, so as to. wet the dispensing sheet with the solvent. The solvent used.

therewith. As soon. as thisbond has been completed by drying, the device is. ready for use. In 4some cases, I have found it desirable lto apply thesolven-tto the lower surface of the base flange .Sei of-theY ring 30, instead of the upper peripheral A5 edge,42 thereof, in which case the fused. bond is formed between-the flange 3l and the annular flange 200i the bottom I8, which` method of bonding', I Ahave found, isl sometimes faster in practice than that just previously described.v

By use of my foregoing described method, I greatly increase the output. of suchy dispensing devices and materially reduce the breakage and injury of parts l,attendant on other methods of `assembly. f It will also'be apparentV that while I ly ave described the top element illustrated in Fig. 6 as, being. assembled first, theV bottom element ,illustrated in- Fig. 5 may be assembled first if desired Without departing from myinvention. Furthermore, .although Ighave described the fabricsupporting element 25 as being pressed into the topeleinentbefore the bottom element is -pressed thereinto=,. which I prefer as it prevents possible distortion ofthe supporting element, obviously, if desired, the fabric-supporting,'element may be merelyv positioned on the bottom element illustrated in Fig. 5 and, as so positioned,.moved into thetopelement with the bottom element. Other simple variations which do not depart from the spirit of the invention will readily occur tov those skilled in the art, and, consequently, I do not. intend-to be limited to the specific method described, but desire to be afforded the full scope of'the'following claims..
