4This invention pertains to devices used in cleaning 5 garments.

~9 In a still further and more specific respect~ the 21 invention pertains to a device for applying a stain-removal 22 agent under pressure which, upon application and release 23 of the pressure, effervesces to assist in physically 24 separating the staininy material from the garment ibers.
~ . ' 26 It is well known that commercially available 27 supersaturated solutions of carbon dioxide, commonly called 28 "carbonated water", have remarkable abilities as s-tain-removal 29 agents when applied to a fresh food or beverage stain. Such solutions are also known to be effective stain-removal agents 551~
1 for a variety of other stalns, such as dust, cigarette
2 ashes, animal stains, regurgitation, etc. Commonly available
3 sources of such solutions include club soda, various naturally
4 occurring sparkling waters, etc.
6 Heretofore, however, the use of such a cleaning 7 agent has been limited by the fact that it is normally 8 unavailable to be used immedia~ely after a garment or other 9 textile material is stained. In the typical case, a customer in a restaurant does not have this simple, yet effective, 11 stain-removal agent available at the time the staining 12 occurs and must wait for a considerable period of time such 13 as his return to his residence or some other location where 14 such cleaning agents are available in bulk containersO This length of time usually is sufficient to enable the stain to 16 "seti' by drying and by impregnation of the fibers of the 17 garment.
19 Furthermore, since the stain-removal action of the agent depends on the effervescent action caused by the 21 release of carbon dioxide bubbles, opening of a large container 2~ of the carbonated water usually results in wastage of all 23 but the initial portion removed fxom the container~ as the 24 remainder of the carbonated water goes "flat".
26 Finally, even when applied by dobbing or pouring 27 portions of the carbonated water upon the stained portion 28 of a garment, there is a tendency for the effervescent 29 action to take place only at the surface of the textile, 31 ratner than in the interstices of the fabric, which limits ~2 ~ 5~
1 the stain-remo~al capab-ility of the agent.
3 Accordingly, it would be highly desirable to 4 provide a device for assisting in the removal of stains from garments and the like which would be readily available 6 when needed, such that the carbonated water stain-removal 7 agent can be applied before the stain on a garmerlt has set.
9 It would also be highly desirable to provide for application of a carbonated water stain-removal agent 11 under pressure and in such ~ashion that ~he unused portion 12 of the stain-removal agent remains usable for later 13 applications.
~4 It is, therefore, a principal object of the present 16 invention to provide a device for assisting in removal of 17 stains from garments.

19 Yet another object of the invention is to provide such a device which is readily available to the customer 21 of a restaurant or other similar establishment.
23 Yet another object of the invention is to provide 24 such a device which permits the use of only a portion of the carbonated water stain-removal agent without wasting 26 the remainder~
28 These and other, further objects of the invention 29 will be apparent to those skilled in the art from the 32 following detailed description -~hereof, taken in conjunction ~ 5~
1 with the drawings, in which:
3 Fig. 1 is a pèrspective view of a device embodying the present invention, showing application of the carbonated water stain-removal agent to a stained portion of a fabric 6 substrate;
8 Fig. 2 is a sectional view of the device of Fig. l, 9 taken along section line 2-2 thereof;

12 present invention constructed in accordance with an alternate 13 e~bodiment thereof; and 1~ ~
Fig. 4 is a sectional view of a device of the 16 present invention constructed in accordance with yet another 17 alternate embodiment thereof.
19 Briefly, in accordance with my in~ention, I provide a device for use in effecting removal of stains from ~arments, 21 comprising, in combination: (a) a reservoir shaped and 22 dimensioned to be concealed on the pexson; (b) a supply of 23 supersaturated aqueous solution of carbon dioxide in the 24 reservoir; and (c~ valve-nozzle means for delivering a portion of the supply of carbon dioxide solution under pressure 26 from the reservoir upon a stained portion of the garment.
28 The shape and dimensions of the reservoir are not 29 critical, so long as the device can be carried on the 31 person, e.g., concealed in a pocket or a purse. Thus, --4~
lZ16551~ ~
1 conveniently, the reservoir can be shaped and dimensioned 2 to the approximate proportions of a conventional tube of 3 lipstick, perfume atomizer, breath freshener cartridge or 4 the like. The materials of construction of the reservoir are not critical and need only have the requisite strength 6 and chemical stability to maintain the slightly acidic 7 solution of carbon dioxide under superatmospheric pressure, 8 so as to maintain the carbon dioxide in ~the aqueous solution 9 until it is released through the valve nozzle. According to one embodiment of the invention, the essentially incom-11 pressible carbon dioxide solution fills only a portion of 12 the reservoir and is ejected therefrom by the pressure 13 of a compressible gas phase filling the remaining portion 14 of the ~eservoir.
16 According to yet another embodiment of the invention, 17 the supersaturated carbon dioxide solution essentially fills 18 the entire reservoir and is either pumped therefrom under 19 pressure or ejected therefrom by deforming the reservoir in the manner of the familiar "sque2ze bottle".
21 ~
22 If desired, the supersaturated carbon dioxide 23 solution can be specially prepared by simply dissolving 2~ carbon dioxide under pressure with the water carrier as is ~5 commonly carried out in drugstore soda fountalns. Altern~tively, 26 the solution can be commercially obtained as ordinary club 27 soda or the like, which optionally may contain additional 28 beneficial ingredients such as sodium bicarbonate, citric 29 a d, etc.
32~ -S-lZl6551!3 1 Turning now to the drawings, in which the presently 2 preferred embodiments of the invention are depicted for 3 purposes of illustration and not by way of limitation on 4 the scope thereof, Figs. 1-2 depict a device constructed in accordance with the presently preferred embodiment of 6 the invention, which consists of a generally cylindrical 7 reservoir 10 haviny a closed end 11 and a dispensing valve~
8 nozzle 12 carried on the opposite end. A supply of carbonated 9 water 13 partially fills the interior of the reservoir 10 and a compressible gas, e.g., CO2, 14 fills the r~maining 11 interior of the reservoir 10, providing a motive force which ~ ejects the carbonated water 13 under pressure through the 13 dip tube 15 when the plunger portion 16 of the valve 12 is 14 depressed in the direction of the arrow A against the action of the spring 17. The supersaturated carbon dioxide solution, 16 indicated by the dashed lines 18l i~ ejected through a 17 flared nozzle 19 and is directed against the stained portion 18 B of a fabric substrate 20 which carries food stain material 19 21.
21 After application of the carbonated water solution 22 18 under pressure from the no~zle 19, the wetted portion of 23 the fabric substrate 20 is dobbed and lightly rubbed with 24 any suitable absorbent material, such as a cloth or paper napkin, to remove the water and the food stain material 21 26 which is separated from the fabric 20. This procedure can 27 be repeated if necessary to effect the complete removal of 28 the staining material.
31 As shown in Fig. 3, the reservoir 31, in accordance 1 with another embocli.ment of the invention, may be completely 2 filled with the carbonated water solution 32 which is ejected 3 under pressure through ~he dip tube 33 by means of a pump 4 34 actuated by a plun~er 35.
.
6 Alternatively, as indicated in Fig. 4, the 7 carbonated water solution 41 can be e~ected from a collapsible 8 reservoir 42 by squeezing to eject the solution 41 through 9 the dip tube 43, overcoming the pressure of the spring 44 on a flapper valve 45.
