Furthermore, the bristle-like elements may be associated with the reservoir means by means of a. perforate backing, enabling the cleansing compound to be dispensed from the reservoir means through the perforate backing and on to the bristle-type elements, the bristle-type elements being either integrally formed with the backing member, as in a' single molding operation, or being separately formed and secured therewith in a conventional brush forming manner. The bristles may comprise substantially any desired material, preferably a material which is readily sterilizable, the bristles being formed, for example, of styrene, polypropylene, natural bristles, nylon, or the like, or, the bristles may be of a hook and/or loop type material made in any desired grade of coarseness and/or thickness as well as in any desired length of the filaments. The reservoir means may comprise, for example, a block of urethane foam, polyurethane foam, natural sponge, sponge latex, sponge porelon, or the like, and the block of foam-like material may be provided with a chamber therewith for containing the cleansing compound or may be impregnated with the cleansing compound and then may be compressed and/or freeze dried to provide a compact and lightweight package which will swell upon wetting with water, or the reservoir means may comprise one or more containers having at least one flexible wall portion.

With reference now to the drawing, and particularly to FIGS. 1-4 thereof, there is shown and illustrated a cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 20.

The cleansing implement comprises scrubbing means 22 and reservoir means 24 adapted to be structurally associated therewith.

The scrubbing means 22 comprises a backing or handle member 26 fabricated of any desired conventional material, such as metal, plastic, ceramic, or the like, and a plurality of elongate bristle-like abrasive or scrubbing elements 28 structurally associated therewith and likewise fabricated of any desired conventional material, such as, for example, styrene, polypropylene, nylon, substantially any other plastic, natural bristles, or the like. The bristle-like elements 28 may be formed independently of the backing or handle member 26, and structurally associated therewith in a conventional brush-forming manner, as by being cemented or adhesively, cohesively or mechanically secured therewith, or may be integrally formed with the backing or handle member 26, as by molding techniques. Regardless of the materials of which the backing or handle member 26 and the bristle-like elements 28 are formed, and the manner of fabrication thereof, the bristle-like elements 28 preferably extend generally outwardly of a lower surface 30 of the backing or handle member 26. The backing or handle member 26 may be of any desired size and configuration, and may be provided with extensions, ears, depressions, grooves, or the like, toassist in grasping and manipulating the implement, if desired. The backing or handle member 26 may be provided with a recess, groove or opening 32 extending generally inwardly from the surface opposite the lower surface 30, or the upper surface 34 thereof, within which the reservoir means 24 is particularly adapted to be disposed. The recess, groove or opening 32 may, for example, be defined by side walls 36, end walls 38, and a bottom wall 40. The backing or handle member 26 may be further provided with one or a plurality of apertures 42 extending relative to the bottom wall for enabling passage of cleansing compound from the reservoir means 24 to the bristle elements 28 during use.

The reservoir means 24 may comprise a block of material 44 fabricated of a material which is of a resilient nature, or of a material which when wetted, as with water, or the like, is of a resilient nature. For example, the block of material 44 may comprise a block of foam-like material such as sponge rubber, natural sponge, or a sponge plastic, such as urethane, polyurethane, propylene, polypropylene, porelon, or the like, or any material, such as paper, felted textile fibers, or the like, which can absorb, adsorb, or contain within or on it an appropriate cleansing compound, and which, at least when wetted, is capable of exuding or dispensing the cleansing compound outwardly thereof. For example, the block of material 44 may comprise a block of foam-like material impregnated with the cleansing compound.

The reservoir means 24 may be either pre-assembled with the scrubbing means 22 so that the cleansing implement 20 may be furnished in a ready-to-use condition or configuration, or the reservoir means 24 may be furnished as a separate unit, capable of assembly with the scrubbing means 22 enabling ready replacement of the reservoir means 24 as the supply of cleansing compound contained therein is used up, or for each pre or post-operative scrub, or the like. The reservoir means 24 may be refillable or may comprise an inexpensive throw-away unit complete with a supply of cleansing compound.

The reservoir means 24 may further comprise protective covering layer means, such as a layer of water soluble material 46, comprising, for example, gelatin or cellulose, enabling the reservoir unit 44 to remain clean and sterile and preventing loss of cleansing compound therefrom during transport, storage, and prior to use, it being merely necessary to run hot water, or the like, over the reservoir means 24 either prior to or following insertion of the reservoir means 24 in the backing member 26 immediately prior to use.

Additionally, the reservoir means 24 may be furnished in a compressed condition enabling more compact storage thereof. For example, the block of material 44 may comprise a polyurethane foam impregnated with the cleansing compound, which following impregnation may be compressed and then freeze dried to form a light-weight, dry and relatively compact block of material which, upon wetting with water, or the like, may swell to its initial size and configuration. Following the compression and freeze drying, the block of material 44 may be covered with the protective covering layer 46. Similarly, the block of material may be freeze dried without compression or compressed without freeze-drying.

With reference now to FIGS. 5 and 6, there is shown and illustrated another reservoir means 24' constructed in accordance with the principles of the present invention and usable with the backing or handle member 26. The reservoir means 24' similarly comprises a block of resilient or foam-like material 44', but, rather than being entirely impregnated with the cleansing compound, the block of material 44' is provided with a generally central opening or chamber 48, the cleansing compound being contained within the chamber 4%. if the cleansing compound comprises a solid, a viscous material, or a comminuted material, then the cleansing compound may be contained within the chamber 48, without any additional means to retain it therein, and the block of material 44 may be compressed and/or dried as heretofore set forth. However, if the cleansing compound comprises a liquid or a hygroscopic material, for example, or any other material which requires or supports the use of additional means to retain it within the chamber 48 or to protect the cleansing compound from atmospheric contact, or the like, then the chamber 48 may be provided with a membrane or wall 50 fabricated of a material which would be readily rupturable upon compression of the block of material 44' to release the cleansing compound'from the chamber 48. Y

The reservoir means 24' may be further provided with protective covering layer means, such as the hereinbefore described water soluble layer or adhesively secured side layers 52, end layers 54 and top and bottom layers 56. The top and bottom layers 56, for example, may be peelable or strippable away from the block of material 44', as shown in FIG. to expose the block of material 44' for use. The

layers

52, 54 and 56 may, for example, comprise waterproof adhesive tape, .or may comprise a gelatin, cellulose, plastic, or the like, coating applied to the block of material 44' and adapted to be at least partially readily removable, as by a stripping or peeling action, and may be provided with preliminary weakening means, such as score lines, or the like, or with tear threads to enable the appropriate portions thereof to be readily removed immediately prior to use.

Of course, the protective covering layer means shown in FIG. 5 is equally adaptable for use with any of the other embodiments or modifications of the present invention, as is the protective layer means of FIG. 2.

In addition to the reservoir means being adapted for structural association with the backing means, as hereinbefore described and disclosed, the bristle-like structures may also be directly associated with the reservoir means. For example, with reference now to FIG. 7, there is shown and illustrated another cleansing implement constructed in accordance with'the principles of the present invention and designated generally by the'reference character 58 wherein the scrubbing means comprises a plurality of bristle-like elements 60 directly structurally associated with a block of absorbent or resilient material 62,-the block of material 62 being fabricated, for example, similarly to the

block

44 or 44. The bristle-like elements 60 may be. either integrally molded with the block of material 62, or may be separately formed and associated therewith in any desired manner, such as mechanically, as by being forced thereinto or by being inserted within apertures provided therein, or may be associated with the surface thereof, as by means of an adhesive, or the like. The cleansing implement 58 may, if desired, be provided with adequate protective layer means, as herein elsewhere described and disclosed.

With reference now to FIGS. 8 and 9, there is shown and illustrated yet another cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 64. The cleansing implement 64 comprises a block of resilient or absorbent material, such as a block of foam or porelon 66 provided on one or more surfaces thereof with a plurality of bristle-like elements 68 extending outwardly therefrom. The bristle-like elements 68 may comprise, for example, a plurality of filaments structurally associated with a backing layer 70, which in turn is secured with the block of material 66, as by means of an adhesive. The filaments 68 and backing layer 70 may be of the material generally referred to as Velcro. The filaments 68 may be of any desired grade of courseness, thickness, length, and spacing. The backing layer 70 is preferably perforated as by being provided with one or a plurality of holes or apertures 72 extending therethrough to enable the passage of cleansing compound from the block of material 66 to the filaments 68. As shown, the cleansing implement 64 may be provided with the material such as VELCRO, a registered trademark of Velcro Corp., on two sides thereof, and it is to be understood that the two of such material (hook and/or loop material elements available from the Velcro Corporation of America of New York, N .Y.) may be either similar or may be of differing coarseness, enabling one side to be used for scrubbing the skin, and the other side, having, for example, longer filaments to be utilized for scrubbing under the nails. The other edges of the block of material 66 may be covered or may be exposed and, if exposed, may also be utilized as cleansing or scrubbing surfaces. The block of material 66 may be either impregnated with the cleansing compound or the cleansing compound may be contained within chamber means formed within the block of material 66, as described and disclosed hereinbefore. The cleansing implement 64 may be further provided with protective layer means, as hereinabove described and disclosed, either fixed or removable. It is also within the scope or ambit of the present invention to utilize VELCRO or a similar material as a scrubbing element either alone or in combination with any other reservoir means. i

Each of 'the cleansing implements hereinabove described and disclosed are readily suitable for many cleansing operations, and particularly, for surgical pre or post-operative scrub purposes, especially when the cleansing compound comprises a germicidal soap compound, such as pl-iisol-lexi in use, the block of material 66 may extend outwardly of the backing means or the scrubbing means, enabling the protective layer means to be readily removed, if provided, and the surface of the block of material utilized for initial scrub purposes, over large areas of skin, or the like. The cleansing compound may be dispensed outwardly to the surfaces thereof by merely squeezing the block of material. For purposes of scrubbing around. and under the nails, for example, thelbristle-like elements, which are likewise supplied with the cleansing compound upon squeezing or kneading of the block of material are eminently suitable. The cleansing compound may also be dispensed directly onto the surface to be cleaned, rather than through the scrubbing means, if desired, and the scrubbing means utilized in a conventional manner.

With reference now to FIGS. 10 and 11, there is shown and illustrated yet still another cleansing implement constructed in accordance with the principles of the present invention and designated-generally by the reference character 74. The scrubbing implement 74 comprises reservoir means 76 and scrubbing means 78 adapted to be structurally inter-associated.

The scrubbing means 78 may, for example, comprise a backing or handle member 89 and a plurality of bristle-like members 82, similar to the scrubbing means 22. The reservoir means 76 is adapted to be structurally as sociated with the scrubbing means 78 and it may comprise a generally tank-like container 84 particularly adapted to contain therewithin a quantity of cleansing compound. The reservoir means 76 may further comprise outlet valve means 86 which may, for example, be of a pressure operated or operable type so that when the cleansing compound within the tank or container 84 is pressurized, the cleansing compound contained therewithin may be dispensed outwardly through the valve means 86. Y

The backing or handle member 80 may be provided with aperture means 88, valve means 86 being particularly adapted to be disposed therewithin. At least the top wall of the tank or container 84 may be fabricated of a generally resilient material, enabling simple finger or hand pressure thereon to pressurize the interior of the tank or container 84, and particularly, the cleansing compound contained therewithin to dispense the cleansing compound outwardly through the valve means 86. The entire tank or container 84 may, if desired, be fabricated of a flexible material, such as plastic film, metal foil, or the like.

The reservoir means 76 may be fabricated, for example, of inexpensive material, such as metal, plastic, coated paper, or cardboard, or the like, and may be furnished as either a throwaway refill unit or, may be refillable, either through the valve means 86 or through another opening provided for that purpose.

Moreover, the scrubbing means may be adapted for use with any or all of the reservoirs by the appropriate provision of aperture.

With reference now to FIG. 12, there is shown and illustrated another and yet still further cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 90. The reservoir is integral with the scrubbing means and is refillable.

The cleansing implement 90 comprises a member 92 having a base wall 94 and a plurality of side walls 96 extending upwardly therefrom. Scrubbing means, such as a plurality of bristle-like elements 98 may be structurally associated with the base wall 94 depending generally downwardly therefrom. The base wall 94 may.

feeder channels 100 to provide fluid communication between the reservoir which is defined by the upstanding walls 96 and the base wall 94 to permit the egress of a cleansing compound contained therewithin outwardly thereof and onto the bristle-like elements 98. The reservoir or chamber 102 is further defined by a top plate comprising, for example, a diaphragm 104 fabricated, for example, of thin plastic or thin metal which is sufficiently resilient and flexible that finger pressure downwardly thereon will force the cleansing compound contained within the reservoir 102 outwardly through the feeder channels or apertures 100. The top wall or diaphragm 104 may be further provided with inlet valve means 106 to enable the reservoir chamber 102 to be filled or refilled, as by means of a tube 108.

The bottom wall 94 may be fabricated of a-resilient material constructed and arranged to automatically close the apertures 104 in the absence of pressure being applied to the top wall 104 and thereby retain the cleansing compound within the chamber during storage.

In each of the embodiments or modifications hereinabove described and disclosed, the cleansing compound is dispensed onto the bristle-like elements by means of pressure applied to reservoir means. It is also within the scope of the present invention to provide the reservoir means in the form of a coating of cleansing compound over the surface of the bristle-like elements to automatically apply the cleansing compound to the surface being cleaned during scrubbing thereof. Accordingly, with reference now to FIG. 13, there is shown and illustrated a portion of yet another cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 110. The cleansing implement 110 comprises a backing member 112 having structurally associated therewith a plurality of bristles or bristle-like elements 114. The bristle-like elements 114 may be either integrally formed with the backing member 112, as by being molded therewith, or may be separately formed and secured therewith, either mechanically or adhesively, as in apertures, in a conventional manner. A layer of cleansing compound 116 may be structurally associated or coated onto the bristles, and/or onto the lower surface of the backing member 112, so that upon contact with water, or the like, the cleansing compound will be dissolved, rubbed off, or placed into solution and into a form for providing cleansing of a surface being scrubbed with the bristle-like elements 114. As in the previous embodiments, a protective covering layer, such as a layer of gelatin or cellulose 118 may then be coated over the surface of to act as a dispenser for directly applying the cleansing compound to be scrubbed.

Accordingly, and with reference now to FIG. 14, there is shown and illustrated a cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 120.

The cleansing implement 120 comprises a block of absorbent material 122 and scrubbing means 124. The block of material 122 may, for example, be a relatively thin and wide block of material impregnated with a cleansing compound, the scrubbing means 124 comprising a backing member 126 having a plurality of bristle-like members 128 extending generally outwardly therefrom in one direction, and a channel 130 formed in the backing member 126 generally opposite the bristles 128, with the edge portion of the block of material 122 being adapted to be disposed within the channel 130. In this embodiment, there is no necessity for the provision of any apertures or channels extending between the channel 130 and the bristles 128, although such may be provided, if desired. In use, the cleansing block of material 122 may be utilized to initially scrub the skin, and to apply the cleansing compoundthereto, the bristles 128 of the scrubbing means 124 being utilized to further scrub the skin, or to scrub around or under the nails, or the like. Moreover, if desired, the block of material 122 may be provided with protective covering layer means, as hereinabove described.

The reservoir means of the present invention may comprise a single reservoir, as hereinabove described and disclosed or, as will be hereinafter described and disclosed, may comprise a plurality of reservoirs capable of being utilized to dispense cleansing compound either independently or concurrently.

Accordingly, and with reference now to FIGS. 15-17, there is shown and illustrated therein a yet further cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 132.

The cleansing implement 132 comprises scrubbing means 134 and reservoir means 136 adapted to be structurally associated therewith. The scrubbing means 134 may, for example, comprise a backing or handle member 138 and a plurality of bristle-like elements 141 depending therefrom. The backing or handle member 138 may be provided with a recess or opening 140 and the reservoir means 136 may comprise a plurality of container elements 142 adapted to be substantially disposed within the chamber or recess 140.

While the backing or handle member 138 may be of substantially any desired configuration, it may comprise a bottom wall 144 having the bristle-like elements 141 projecting from the lower surface thereof, a pair of side walls 146 and a pair of end walls 148 projecting from the upper surface thereof and defining therewith the chamber or recess 140.

The reservoir elements or containers 142 may be of generally tubular configuration, fabricated of a resilient material such as plastic film, metal foil, or the: like, and containing therewithin a quantity of cleansing compound. One end portion of each of the reservoir members or containers 142 may be permanently closed, as by means of heat sealing 150 and the other end portions of the reservoir members or containers 142 closed in a manner enabling passage outwardly thereof of the cleansing compound under specified conditions, as by means of narrow heat seals 152.

The

150 and 152 may be formed in substantially any desired manner; however, as hereinbefore pointed out, for simplicity and economy of manufacture it is preferable that the

seals

150 and 152 be formed, as by heat sealing. The seals 150 preferably are constructed and arranged as to preclude inadvertent opening of that end of the reservoir elements or containers 142, as by being formed by a relatively wide heat seal, or by means of a folded and sealed connection. The seals 152 are preferably constructed and arranged to rupture or fail, that is, to open that end of the reservoir element or container 142 upon the application of finger pressure to the reservoir elements or containers 142 to pressurize the quantity of cleansing compound contained therein. The seals 152 are further preferably constructed and arranged to provide a nozale-type outlet or dispensing outlet upon such rupture, and may, for example, comprise relatively narrow heat seal connections or heat sealed connections defined by a plurality of small area adjacent heat seals. The seals 152 may be constructed and arranged to direct a flow of cleansing compound generally axially outwardly of the reservoir elements or containers 142 upon the application of finger pressure thereto, or may be constructed and arranged to provide such flow of cleansing compound obliquely to the reservoir element axis.

If the seals 152 are fabricated to provide a generally axial flow of cleansing compound, then the cleansing implement 132 would be utilized by pointing that end of the implement toward the area to be cleaned, applying finger pressure to one or more of the reservoir elements 142 and directing the resulting stream or flow of cleansing compound onto the area being cleaned or scrubbed. After the application of the cleansing compound to the area to be cleaned or scrubbed, the bristle-like elements 141 are manipulated in a standard brush-type manner to thoroughly cleanse and scrub such area. If, however, the seals 152 are constructed and arranged to direct the flow or stream of cleansing compound obliquely to the container axes, then the stream of cleansing compound may be directly applied to the area to be scrubbed as described above, or, the stream or flow of cleansing compound may be directed in generally the same direction as the bristle-like ele ments 141 so that the cleansing compound may be applied simultaneously with the manipulation of the bristle-like elements 141.

The reservoir elements or containers 142 may be retained in structural association with the handle or backing member 138, as by having the end portion thereof inserted within apertures or holes 154 provided in each of the end walls 148 of the handle or backing member 138.

in use, finger pressure may be applied to all of the reservoir elements or containers 142 simultaneously to thereby dispense the quantity of cleansing compounds contained therein, or finger pressure or the like may be applied to only one of the reservoir elements or containers 142 at a time, so that separate cleansing opera tions may be undertaken utilizing a fresh supply of cleansing compound for each cleansing operation. At any time, one or more of the exhausted reservoir elements or containers 142 may be readily replaced. Moreover, a plurality of different types of cleansing compounds containing reservoirs may be utilized in a single handle, so that, for example, an initial scrub operation may be undertaken utilizing one variety or type of cleansing compound, followed by a scrubbing operation utilizing a differing type of cleansing compound, without necessitating a pause to change or replace the reservoir elements or containers 142.

As hereinbefore pointed out, the reservoir elements or containers may be constructed and arranged to direct the stream or flow of cleansing compound directly onto the area to be scrubbed with the cleansing implement in its normal position or the stream or flow of cleansing compound may be directed onto the bristle area. Moreover, the backing or end member may be slightly modified to further aid in directing the stream or flow of cleansing compound to the bristle area.

For example, and with reference now to FIGS. 18 and 19, there is shown and illustrated another cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 132'. The cleansing implement 132' is substantially similar to the cleansing implement 132, and accordingly, like parts are designated by like reference characters, the reference characters being primed.

The base wall 144 may be provided, adjacent one end portion thereof, with an elongate aperture or slot 154' extending therethrough with the sealed end portions 152' of the reservoir members or containers 142' extending downwardly therethrough. The permanently sealed end portions 151) of the reservoir elements or containers 142 may be retained within holes or apertures provided in the opposite end wall 148', or, as shown, may be secured by means of a lip or plate portion 156 extending transversely adjacent the opposite end wall M3. The reservoir elements or containers 142' may be either preformed with the sealed end portions 152 extending obliquely, or the end portions 152 may be bent into the illustrated configuration during insertion of the reservoir elements or containers 142' in the handle or backing member 138. For example, if the reservoir elements or containers 142' are formed to a generally straight configuration, then they may be inserted within the opening or chamber 140 of the handle or backing member 138 by initially inserting the end portions 152' into the elongate aperture or slot 148' with the reservoir elements or containers 142 in a generally vertical position, followed by bending the main portion of the reservoir elements or containers 142' and inserting the closed ends 150 thereof beneath the lip 156. With the reservoir elements or containers assembled and operatively associated with the handle or backing portion 138, the cleansing implement 132 may be utilized in the manner heretofore described and disclosed.

Additionally, the reservoir elements or containers 142 may themselves be compartmentalized, as by providing a sealed region generally centrally thereof, and fabricating both heat sealed

regions

150 and 152 to be readily rupturable. Hence, pressure adjacent one end portion of each of the reservoir elements or containers 142' will cause a dispensing of cleansing compound outwardly of the adjacent end while pressure at the other end portion thereof, either simultaneously or subsequently, will cause a dispensing of cleansing compound through the heat seal adjacent to that end portion.

Moreover, and with reference now to FIGS. and 21, there is shown and illustrated yet another cleansing implement constructed in accordance with the principles of the present invention and designated generally by the reference character 160. The cleansing implement 160, similarly to the cleansing implements previously described and disclosed comprises scrubbing means 162 provided with bristle-like scrubbing elements 164 extending outwardly thereof and removable and replaceable reservoir means 166 adapted to be structurally associated therewith.

The scrubbing means 162 may, for example, comprise a backing or handle member 168, which in turn comprises a base portion 170, the bristle-like elements 164 extending outwardly from the lower surface thereof and a plurality of generally upstanding side walls 172 to define a channel 174 for removably receiving therewithin the reservoir means 166.

The reservoir means 166 may be of generally rectangular configuration having bottom wall means 176, side wall means 178, top wall means 180, and end wall means 182. At least the top wall means 180 is preferably of a flexible or resilient material, enabling finger pressure thereto to pressurize a quantity of cleansing compound contained therein.

At least one of the end walls 182 may be provided with nozzle means 184 adapted to direct a flow of cleansing compound outwardly and downwardly of the reservoir means 166 so that when the reservoir means 166 is disposed within the channel 174 of the scrubbing implement 162, the flow of cleansing compound will be directed towards or adjacent the bristle-like elements 164. The nozzle means 184 may be provided with closure means, such as a narrow heat sealed region 186 adjacent the end thereof adapted to be ruptured or opened upon application of finger pressure to the top wall 180 of the reservoir means 166 and to thereby form a discharge nozzle to direct the flow of cleansing compound to the bristle region.

The reservoir means 166 may be further constructed and arranged to provide a plurality of compartments or separate reservoirs for containing the cleansing compound, as by providing the nozzle means 184 at each end thereof, and cornpartrnenting means or wall means 188 generally medially of the reservoir means 166. The reservoir means 166 may be fabricated as two separate similar halves, the end walls 188 of each of the reservoir halves being abutted together, and the reservoir halves joined, as by heat sealing adjacent the walls 188 to define the entire reservoir means 166. The reservoir means 166 may be fabricated entirely of a flexible and resilient material, such as plastic film, metal foil, wax or plasticized paper, or the like and may be either refillable or disposable.

Moreover, it is within the ambit of the present invention to provide cleansing implements of the class described wherein the scrubbing means is defined by the surface of the reservoir means, as, for example, by providing a block of foam-like material, such as a foamed plastic, poleron, or the like, or substantially any absorbentor adsorbent material, the surface and texture of which'is specifically chosen for the particular cleansing operation desired, and may be firm, stiff and rough, for example, for surgical scrub use, or may be relatively soft and smooth, for example, for cleansing sensitive areas, such as on a baby's skin. In any event, however, the block of material is preferably saturated or impregnated with an appropriate cleansing compound, such as pl-lisolrlex solution. Furthermore, if separate scrubbing means is provided adapted to be structurally associated with the reservoir means of the present invention, the scrubbing means preferably is fabricated of materials capable of being sterilized by conventional techniques, such as, without limitation, gas autoclaving, steam autoclaving, boiling, immersion in germicidal, bactericidal or fungicidal solutions, or the like.

While the present invention has been hereinabove described and disclosed particularly in terms of scrubbing implements especially for surgical pre or post-operative scrub purposes, it is to be expressly understood that this exemplary use is disclosed herein for exemplary purposes only, and the invention is not to be deemed limited thereby. For example, cleansing implements constructed in accordance with the principles of the present invention may also be utilized for many other purposes, such as, for example, by substituting a fungicidal compound for the cleansing compound, the present invention is eminently suitable for use in prophylaxis and treatment of fungicidal infections, such as athletes foot. Moreover, by the substitution of a shampoo type compound, the present invention is equally suitable for shampoos, or the like, or with either a mild soap or a germicidal soap, such as Phisohex, for home use in ordinary skin care.

in any case, the present invention provides cleansing implements which are inexpensive, readily sterilizable, and simple and easy to use.

It is to be understood that substantially any material having absorbent qualities, either rigid and with the compound released by water action or flexible, with the compound being released by water action plus pressure, such as felted fibrous pads, gauze pads, cheesecloth, knitted or woven fabric pads, or the like, may also'be utilized in this invention without departing from the scope thereof.

Additionally, implements may be constructed in accordance with the present invention substantially identical to any of the embodiments hereinelsewhere described and disclosed wherein the backing member or handle is not provided with any apertures, slits, orifices, or the like, adjacent the bristles and the foam block may be adapted for direct application of the compound to the surface being treated or cleansed. For example, the foam block may be enlarged so as to project outwardly of the rear of the backing member or handle, that is, oppositely of the bristle-like members. in use, such an implement would be used inverted, that is, with the foam block in contact with the skin or other surface to be cleansed or otherwise treated to apply the compound thereto, and then the implement turned over for scrubbing the skin.

Furthermore, if desired, an additional flexible cover, such as a plastic cover, may be positioned over the foam block so that the cover and the handle or backing member together enclose the foam block. The cover may be provided with apertures for enabling water or the like to enter and mix with the-soap or other compound in the foam block or reservoir. The cover would preferably be fabricated with at least a portion thereof being flexible so that digital or finger pressure thereon may force the compound or compound-water solution or mixture outwardly to the bristles. The cover may be of substantially any shape, i.e., formed with a handle on it, or concave, or the like, if desired.

Preferably, implements constructed in accordance with the present invention are of such a size and configuration as to be easily gripped and manipulated by the fingers of one hand. Moreover, implements constructed in accordance herewith may be fabricated of such materials, such as plastics, and constructed and arranged as to be substantially flexible, enabling the implement to be squeezed, kneaded, twisted or otherwise modified or manipulated to reach substantially any desired areas of the hands, or the like, such as the base of the hand between the fingers. The handle or backing member may also be provided with orifices, apertures, openings, ribs, striations, corrugations, or other surface treatments or configurations to allow compound flow therethrough or to give a firm digital or finger grip while scrubbing.

The reservoir means of the present invention may further comprise one or more blocks of foam-like material glued or otherwise secured with the outer side surfaces of the handle or backing member, enabling the under surface of the foam-like blocks to dispense the compound or soap.

Still further, the reservoir means of the present invention may comprise one or a plurality of capsules or chamber members adapted to be inserted within the recess of the backing member or handle and adapted to have the lower wall portions thereof pierced by means of piercing pins or the like provided or integrally formed with the handle or backing member projecting into the recess thereof, that is, projecting oppositely of the bristles from the bottom wall of the handle or backing member. Such capsules may be engaged and pierced by the piercing members, and the compound dispensed to the bristle region of the implement by direct finger or digital pressure to the capsule.

As another feature of the present invention, the density, size, and shape of the bristles in the array present a brush which effectively serves as a personal scrubbing brush as well as apreand post-surgical brush. Further, the brush also is capable of effectively cleaning not only the surface areas of the users hands but also under the fingernails. This feature enables an extraordinary sterile cleansing brush which more effectively enables medial personnel to safely work in the surgical field.

As still another feature of the present invention, the handle member is arranged so as'to permit longitudinal flexing of the brush to more effectively enable the brush to clean by contouring it to the surface to be cleaned. To this end, handle 26 comprises a base portion 200 and a plurality of spaced apart retaining struts 202 upwardly disposed from the base member. Since there are spaces between these struts, the handle 26 is capable of being longitudinally bent when the handle is fabricated of a suitable flexible material, such as plastic or polyethylene. The block of absorbent material 122 is held in the handle and rests within the base member and supporting struts. To further enhance the longitudinal flexibility of the handle, single side support struts 204 are located at each end of the handle and maintain the reservoir means from sliding out from the scrubbing implement. As an alternative, a plurality of such side support struts 206 spaced apart from each other may be utilized.

With the present invention, effective cleansing action is achieved both on the surface of the users hands as well as under the nails. it has been found that the density of the bristles is significant and in this regard, when the bristles are spaced too far apart the stiffness of each is not maintained and they bend too easily hampering their effectiveness. Further, when the bristles are too close to each other, a duck pin effect is achieved because as one bends it pushes the contiguous bristles. It may be understood that such action minimizes the effectiveness of such a cleansing instrument under the users nails. In accordance with the principles of the present invention, there are approximately 17 bristles per longitudinal inch with 16 rows of such bristles located across 1 ac inches. The density of the bristle array is approximately per square inch. It is understood that although the approximate density is presented, this figure is only illustrative of a bristle density which effectively accomplishes the above functions. Further, the bristles comprise a flexible material, such as polyethylene.

in accordance with still another feature of the present invention, the shape of the bristle also enhances the cleaning operation and, to that end, the bristles are tapered triangular projections with relatively flat sides 208 aligned longitudinally. This triangular shape also enhances the flow of cleansing material to the tip of the bristles by suitable capillary action. Further, the bristles end in a hair like projection 210 which is slighdy curved to further enhance the cleansing action obtained with the present implement.

in operation, the block of absorbent material is squeezed as water passes thereover and the cleansing material is carried through the base 2% to the bristles.

A plurality of longitudinally extending slots 212 are located in base 200 which allows the cleansing solution to pass from the top of the base to the bottom thereof and then to the bristles. As still another embodiment, a plurality of slits 214 are provided in the sides of the base 200 allowing the cleansing material to flow out the sides of the base and down to the bristles. As still another embodiment for conducting the cleansing solution from the block of absorbent material, a plurality of conducting tubes 216 are provided with orifices 218 facing the block and orifices 220 facing the bristles. As still another embodiment for conducting the cleansing material to the bristles, a plurality of sloped grooves 222 are provided in the base 200 of the handle with the grooves terminating in orifices 224 which carry the cleansing solution to the bristles.

It is to be expressly understood that terminology such as upper, lower", bottom, top, inwardly and outwardly, as used in the preceding description and in the subjoined claims, along with other similar directional terminology, is to be construed and interpreted in its normal and accepted sense. However, such terminology is not to be construed and interpreted in a limiting sense either in the preceding description or the subjoined claims, since the same is used merely to facilitate an understanding of, and to clearly set forth and particularly define the present invention.
