FlLlUllD xrsucxrous This invention relates to the art of fluid applicators and more particularly concerns an applicator having a porous body for applying a liquid or semifluid substance to a surface, the porous body enclosing a container or plurality of containers which have one or more fluids therein.

It has been proposed heretofore to provide a bandage with an attached or enclosed capsule containing a liquid. Such devices are shown in U.S. Pat. Nos. 2,336,024 and 3,366,112. In U.S. Pat. No. 2,336,024 the capsule forms part of a tissue and is exposed when the tissue is opened. The contents of the capsule are not dispensed through the tissue. In U.S. Pat. No. 3,366,] 12 a capsule is partially enclosed in an adhesive bandage. The capsule being exposed when the bandage is opened. Other structures have been proposed of which U.S. Pat. No. 3,306,292 is typical, in which a multilayer, toroidal-shaped capsule is disposed in a bandage. The capsule however is not enclosed in a porous body used as an applicator.

According to the present invention, a porous body which may have one, two or more layers or sheets of porous material encloses a container made of thin, nonporous film or foil material. Inside the container is a fluid or semifluid material such as a liquid, lotion, paste, salve, polish or the like. The fluid is released by applying pressure to the container through the porous body which ruptures the container. The released fluid disperses and permeates the porous body. The applicator can then be applied to the surface to be treated. Such surface may be rigid or flexible, porous or nonporous, rough or smooth. The treatment may involve cleansing, polishing, painting, medicating, oiling, etc. Instead of sheets of porous material, the porous body may be a mass or wad of absorbent material such as cotton, felt, or the like. The applicator may be rectangular, round or of other geometrical shape. It may have flat or curved sides. It can be disk-shaped, spherical, cubical, etc. Inside the container may be one or more walls dividing it into compartments which contain different fluids. The container can be constructed so that the inner walls break first under pressure to mix the fluids before the walls of the container break to release the mixture into the surrounding porous body.

It is therefore one object of the invention to provide applicator means for delivering liquids, fluids and semifluids such as creams and pastes in a predetermined quantity, releasable at will.

Another object is to provide a fluid applicator in which a predetermined quantity of a fluid is safely enclosed and hermetically sealed so that it can be stored or carried but which is ready for dispensing the fluid at any time.

A further object is to provide a fluid applicator comprising a porous possibly absorbent body in which is a frangible container having one or more compartments containing one or more fluids, the body possibly having one side covered by a nonporous protective member to protect the users fingers from contact with the fluid while permitting passage of the fluid out of the other side of said body.

A further object is to provide a fluid applicator as described, wherein the plurality of compartments in the container are defined by individual frangible capsules of the same or different sizes and containing the same or different fluids.

The above and other objects and advantages of the invention will become apparent from the following detailed description taken together with the drawings, wherein:

In the following detailed description of the invention the term fluid is intended to mean a flowable substance of any viscosity. The viscosity may range from that of water substances such as alcohol and ether through that of creams and oils to that of highly viscous substances such as pastes and waxes.

Referring now to the drawings, there is shown in FIGS. I and 2 a first fluid applicator A-ll. This applicator comprises abody 25 made of twoporous sheets 26. The sheets are juxtaposed face-to-face and are bonded to each other. These sheets may be made of fibrous, cellular, plastic or the combination thereof; such as, blotting paper, sponges, cloth cellulose, plastic which may be perforated, and the like which are highly porous. They are sufficiently liquid resistant to retain their shape when wet by the fluid which they apply. Between the sheets is achamber 27 in which is a container CI; see FIGS. 2. The container is a closed hermetically sealed member withfrangible walls 23. The container is rectangular in plane view and contains afluid 30. Theedges 32 of the walls are abutted to form abreakable seal 33 all around the container. The walls being weakened by scored lines 34l so that the container will break all around its periphery and at the sides when pressure is applied manually at opposite sides of the applicator. Under exerted pressure thewalls 25 of the container, could rupture at points other than the weakened areas. Thewalls 25 of the container are nonporous. They may be made of any suitable material such as metal foil, rigid or flexible plastic material or the like, which if desired, may be laminated. Thewalls 28 are bonded atedges 32 by heat, pressure, cementing, crimping or any other suitable method, provided that theseal 33 formed at the abutted edges will break under pressure to release fluid 30 into the porous possibly absorbent sheets surrounding the container. The applicator can be used for applying cleanser, polish, medicament, cosmetic, paint, oil, etc., to any suitable surface to be treated. If desired, the scoredwalls 28 can be weaker than theseal 33 of theedges 32 so that the walls break laterally first to release a controlled amount of fluid. Further pressure then breaks theseal 33 to open the container all around and release all the fluid into the surrounding porous, possiblyabsorbent sheets 26. The juxtaposed faces 35 ofsheets 26 can be bonded together at all points of surface contact, only or in spots, lines or areas thereof.

FIG. 4 shows applicator A2 having a body 25a formed by two thickrectangular pads 26a, 26a. The pads are bonded together at juxtaposed faces 35a. Embedded inchamber 27a is container C2 which is similar to container CI. Otherwise, parts of container C2 corresponding to those of container CI are identically numbered. Covering oneside 42 of onepad 26a is a thin nonporous sheet, possibly metal or plastic. This sheet is nonporous to prevent penetration offluid 30 throughside 42 ofpad 26a on the applicator after the fluid is released by breaking container C2. Although two pads are shown in applicator A2 it is possible to make the porous body from a single thick pad with container C2 embedded in the center of the pad.

Applicator A3 shown in FIGS. 5 and 6 is rectangular. It includes a porous, possibly absorbent, body 25b made of a single thick porous pad or sheet 26b of any thickness.Nonporous sheet 40b covers one side of the pad. Container C3 is diskshaped as clearly shown in FIGS. 6 and 7. Peripheral marginal edges 32b of the container are abutted and bonded to form seal 33b.Fluid 30 is retained in the hermetically sealed container. Scored lines 34b on one or both circular walls 28b of the container may be weaker than seal 33b to break first when pressure is initially applied, and then seal 33b will break as further pressure is applied to permeate the pad with the fluid in concentrated amounts to a specific part of the surface of theporous body 25!).

Applicator A4 shown in FIGS. 8 and 9 has a spherical, porous body 250. Inside the porous body is a spherical container C4. The container has radial annular edges 32c joined to form abreakable seal 33c. The spherical container has two nonporoushemispherical walls 28c joined at edges 320; see FIGS. 9 and 10. When pressure is applied to thespherical body 25c, the container will break at scoredlines 34c. When further pressure is applied, the circumferential seal 330 will open. The fluid 30 will saturatebody 25c so that it can be used as an applicator pad.

Applicator A5 of FIGS. 11 and 12 employs the same sphericalporous body 25c as applicator A4 in which is embedded frangible container C4. A hemisphericalnonporous cover 400 is applied to one side of body 250 to serve as a handle and prevent penetration offluid 30 at that side.

Applicator A6 of FIG. 13 has a sphericalporous body 25d covered on one side with hemisphericalnonporous sheet 40d.Inside body 25d is a spherical container C5. The hemisphericalnonporous walls 28d of the container are joined by acircumferential seal 33d between radialannular flanges 32d; see FIG. 14. Inside the container arehemispherical capsules 55a and 55b defining two compartments in which are twodifferent fluids 30a, 30b. Flatcircular walls 57 of the two capsules are abutted. These walls are weakened by scoredlines 60. When pressure is applied to container C5, asbody 25d is squeezed,walls 57 will become distorted and will then break to mixfluids 30a, 30b together. Then as further pressure is applied theseal 33d will break to release the mixture of fluids intoporous body 25d. The saturated porous body can then be used as an applicator pad to apply the fluid mixture to any desired surface.

Fluid applicator A7 as shown in FIG. 15 has a rectangularporous body 25e in which is embedded a rectangular container C6. Container C6 hasperipheral edges 32e ofrectangular walls 28e abutted and secured by abreakable seal 33e; see FIG. 16. Inside the container is acentral dividing wall 65. The wall divides the container into capsules orcompartments 66a, 66b containingdifferent fluids 30a and 30b respectively. Thethin wall 65 will become broken or displaced when pressure is applied to the container viabody 25e. The fluids will then mix in container C6. Thereafter theseal 33 will break as further pressure is applied to discharge the fluid mixture into the porous body.

FIGS. 17 and 18 show another container C7 which can be used in place of any of other containers C1-C6 in the applicator pads previously described. Container C6 is round and has two opposed cup-shapedwalls 28f, 28f Radialannular edges 32f ofwalls 28f are abutted to a circular wall orpartition 70 disposed betweenwalls 28f, 28f and secured byseals 33f. The cup-shapedwalls 28f and 281 define two capsules filled with twodifferent fluids 30a, 30b.Wall 70 may have scoredlines 72 to weaken it and cause it to break beforeseals 33f for mixing the fluids before the mixture is discharged in the porous body of the applicator pad in which it will be placed.

FIGS. 19 and 20 show another container C8 having three compartments defined by two nonporous cup-shapedwalls 28g, 28g and adisklike capsule 28g"'interposed between thewalls 28g, 28g. In addition the twodifferent fluids 30a and 30b in the container are separated bycapsule 28g" which contains a third different fluid 30c.Nonporous walls 74 of capsule 283 are scored bylines 75 so that they will break first before seals 33g formed between radialannular flanges 32g and 32g of thewalls 28g, 28g and 28g". Container C8 can be used in place of containers C1-C7 in all the applicators previously described. If desiredfurther score lines 76 stronger than scoredlines 75 but weaker than seals 333 can be formed inwalls 28g, 28g.

FIGS. 21 and 22 show another applicator A8. Rectangularporous pad 25h is covered by a nonporous protective sheet or plate like 40!: applied to one side of the body. Insidepad 25h is a disklike container C9 best shown in FIGS. 22 and 23. This container has two cup-shapedwalls 28h secured together by abreakable seal 33h between radialannular flanges 32h. Inside the container is a multiplicity ofspherical capsules 80 of different sizes containingdifferent fluids 30h. The capsules have scoredlines 80 formed on their nonporous breakable walls. These capsules will break at different times depending on the applied pressure to provide a controlled release of different fluids. Two or more different fluids can be mixed by breakage of two or more capsules. Usually the capsules will break inside the container which will then break at bothseal 33h and at score lines 85. Capsules C9 can be used in any of the other applicator pads previously described.

In all forms of the invention described one or more fluids are enclosed in nonporous breakable containers for saturating a porous applicator pad in which the containers are embedded. If desired, two or more containers of different fluids can be provided in the same applicator pad for dispensing different fluids or a single container may have more than one compartment or capsule containing different fluids. The containers can be provided separately from the pads. The user can insert successive containers into a single pad. Thus one porous pad may be used over and over again for a succession of containers.

Although a limited number of applicator pads and containers have been described, many other variations are possible within the scope of the invention.
