Description:
CROSS REFERENCE TO RELATED APPLICATION  
       [0001]     The present application is a continuation-in-part of Co-pending application Ser. No. 10/817,606, which was filed Apr. 1, 2004, entitled “ERGONOMIC CLEANING PAD”, and incorporated herein. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates generally to devices for cleaning hard surfaces, soft surfaces and human and animal skin surfaces. The invention also relates to cleaning substrates with an interior surface for inserting a hand. The substates of the invention can have additional uses such as attachment to cleaning devices. The substrates can be impregnated with a treatment composition. The substrates can also be free of treatment composition.  
         [0004]     2. Description of the Related Art  
         [0005]     A variety of mitts are known in the art. U.S. Patent App. 2003/0141204 to Yuskaitis, U.S. Pat. No. 6,192,543 to Lee, U.S. Pat. No. 5,979,007 to Soon, U.S. Pat. No. 5,864,883 to Reo, U.S. Pat. No. 5,829,089 to Steadmanm, U.S. Pat. No. 5,807,296 to Stubbs, U.S. Pat. No. 5,649,336 to Finch et. al., U.S. Pat. No. 5,373,601 to Miller, U.S. Pat. No. 4,807,322 to Littledeer, U.S. Pat. No. 5,134,746 to William, U.S. Pat. No. 3,806,260 to Miller, and U.S. Pat. No. 3,793,121 to Eberly, Jr. et al. disclose mitts which are intended to cover the entire hand and generally have a tightening area for the wrist. Other mitts are described that are intended to cover a finger or multiple fingers only, for example, U.S. Pat. Nos. 6,669,387 and 6,508,602 to Gruenbacher et al.  
         [0006]     We have found that a device that fits over all of the fingers but less than the entire hand has ergonomic advantages for the consumer. It is therefore an object of the present invention to provide a device that overcomes the disadvantages and shortcomings associated with prior art devices.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0032]     Before describing the present invention in detail, it is to be understood that this invention is not limited to particularly exemplified systems or process parameters that may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments of the invention only, and is not intended to limit the scope of the invention in any manner.  
         [0033]     All publications, patents and patent applications cited herein, whether supra or infra, are hereby incorporated by reference in their entirety to the same extent as if each individual publication, patent or patent application was specifically and individually indicated to be incorporated by reference.  
         [0034]     It must be noted that, as used in this specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the content clearly dictates otherwise. Thus, for example, reference to a “surfactant” includes two or more such surfactants.  
         [0035]     Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention pertains. Although a number of methods and materials similar or equivalent to those described herein can be used in the practice of the present invention, the preferred materials and methods are described herein.  
         [0036]     As used herein, the term “hand article” refers to a covering for the hand or portion of the hand such as a finger or thumb. The term “disposable” is used herein to describe hand articles that are not intended to be restored or reused (i.e., they are intended to be discarded after a single use or a limited number of uses (typically three or less), and to be recycled, composted or otherwise disposed of in an environmentally compatible manner). As used herein, the term “mitt” refers to a hand article having an enclosure that leaves the fingers unseparated on the external surface and that may include space for the thumb in the main enclosure or may provide space for the thumb in a separate enclosure for the thumb or may not include a thumb enclosure at all.  
         [0037]     The cleaning device can be used as a disinfectant, sanitizer, and/or sterilizer for cleaning a surface. As used herein, the term “disinfect” shall mean the elimination of many or all pathogenic microorganisms on surfaces with the exception of bacterial endospores. As used herein, the term “sanitize” shall mean the reduction of contaminants in the inanimate environment to levels considered safe according to public health ordinance, or that reduces the bacterial population by significant numbers where public health requirements have not been established. An at least 99% reduction in bacterial population within a 24 hour time period is deemed “significant.” As used herein, the term “sterilize” shall mean the complete elimination or destruction of all forms of microbial life and which is authorized under the applicable regulatory laws to make legal claims as a “Sterilant” or to have sterilizing properties or qualities.  
         [0038]     In the application, effective amounts are generally those amounts listed as the ranges or levels of ingredients in the descriptions, which follow hereto. Unless otherwise stated, amounts listed in percentage (“%&#39;s”) are in weight percent (based on 100% active) of the cleaning composition alone, not accounting for the substrate weight. Each of the noted cleaner composition components and substrates is discussed in detail below.  
         [0039]     As used herein, the term “substrate” is intended to include any material that is used to form the device. Examples of cleaning substrates include, but are not limited to nonwovens, sponges, films and similar materials.  
         [0040]     As used herein, “film” refers to a polymer film including flat nonporous films, and porous films such as microporous, nanoporous, closed or open celled, breathable films, or apertured films.  
         [0041]     As used herein, “wiping” refers to any shearing action that the substrate undergoes while in contact with a target surface. This includes hand or body motion, substrate-implement motion over a surface, or any perturbation of the substrate via energy sources such as ultrasound, mechanical vibration, electromagnetism, and so forth.  
         [0042]     As used herein, the term “fiber” includes both staple fibers, i.e., fibers which have a defined length between about 2 and about 20 mm, fibers longer than staple fiber but are not continuous, and continuous fibers, which are sometimes called “continuous filaments” or simply “filaments”. The method in which the fiber is prepared will determine if the fiber is a staple fiber or a continuous filament.  
         [0043]     As used herein, the terms “nonwoven” or “nonwoven web” means a web having a structure of individual fibers or threads which are interlaid, but not in an identifiable manner as in a knitted web. Nonwoven webs have been formed from many processes, such as, for example, meltblowing processes, spunbonding processes, and bonded carded web processes. The basis weight of nonwoven webs is usually expressed in ounces of material per square yard (osy) or grams per square meter (gsm) and the fiber diameters useful are usually expressed in microns, or in the case of staple fibers, denier. It is noted that to convert from osy to gsm, multiply osy by 33.91.  
         [0044]     As used herein, the term “polymer” generally includes, but is not limited to, homopolymers, copolymers, such as for example, block, graft, random and alternating copolymers, terpolymers, etc. and blends and modifications thereof. Furthermore, unless otherwise specifically limited, the term “polymer” shall include all possible geometrical configurations of the molecule. These configurations include, but are not limited to isotactic, syndiotactic and random symmetries.  
         [0045]     The term “sponge”, as used herein, is meant to mean an elastic, porous material, including, but not limited to, compressed sponges, cellulosic sponges, reconstituted cellulosic sponges, cellulosic materials, foams from high internal phase emulsions, such as those disclosed in U.S. Pat. No. 6,525,106, polyethylene, polypropylene, polyvinyl alcohol, polyurethane, polyether, and polyester sponges, foams and nonwoven materials, and mixtures thereof.  
         [0046]     The term “cleaning composition”, as used herein, is meant to mean and include a cleaning formulation having at least one surfactant.  
         [0047]     The term “surfactant”, as used herein, is meant to mean and include a substance or compound that reduces surface tension when dissolved in water or water solutions, or that reduces interfacial tension between two liquids, or between a liquid and a solid. The term “surfactant” thus includes anionic, nonionic and/or amphoteric agents.  
         [0000]     Cleaning Device Shape  
         [0048]     The cleaning device shape is designed to ergonomically fit the task. For shower and similar cleaning, the device must conform to cleaning surfaces to allow cleaning of corners, tile grout and textured surfaces, faucet and shower door handle area, and shower tracks. The cleaning device may have a functional edge capable of getting into shower tracks, curved surfaces to fit the curves in a bathtub, optimal stiffness to allow access to corners, and optimal thickness and compressibility to allow contact with all corners in the tub. For cleaning the human body, there are also recesses and curved surfaces that are more easily cleaned when the device is conformable to the appropriate surfaces. We have found that certain size, shape and compressibility parameters are useful to allow the cleaning device to conform to irregular cleaning surfaces and improve the cleaning experience compared to prior art cleaning devices.  
         [0049]      FIG. 1  illustrates a cleaning device attached to a cleaning implement having a handle  10 , a cleaning head  12 , and a joint  11  attaching the handle  10  to the cleaning head  12 . The cleaning head  12  attaches to a removable cleaning device  13 . The removable cleaning device  13  can have a scrubbing layer on the bottom surface  15  and an attachment layer on the top surface  14 . The thickness of the cleaning device  13  is measured from top surface  14  to bottom surface  15 .  
         [0050]      FIG. 2A  illustrates a cleaning device covering four fingers but not the carpals area of the hand.  FIG. 2B  illustrates a cleaning device covering four fingers and the thumb but not the carpals area of the hand.  FIG. 2C  illustrates a cleaning device covering four fingers but not the carpals area of a hand.  FIG. 2D  illustrates a comparative cleaning device covering the entire hand including the carpals area.  
         [0051]      FIG. 3  illustrates a useful shape for a cleaning device. The cleaning device has a top end  31  and a bottom end  32 . The top end is the end that normally moves away from the user as the user pushes the cleaning implement away from his body. When attached to a cleaning implement such as in  FIG. 1 , as the joint is turned, the sides may also move away from the user. The cleaning device has one side  33  and another side  34 . The length of the cleaning device is measured from the top end  31  to the bottom end  32  at the longest point. The width of the cleaning device is measured from one side  33  to the other side  34  at the widest point. Segments  30  as they approach the top end  31  may define the cleaning angle, which is the angle formed by the intersection of segments  30 .  
         [0052]      FIG. 4  illustrates a cleaning device with a cleaning arc, whose length is the distance from one end of the curved portion  41  to the other end of the curved portion  42 , but where the cleaning arc only extends on one side of the cleaning device, as shown in  FIG. 4 .  
         [0053]     Suitable combinations of length, length to width ratio, cleaning arc, cleaning angle, thickness, and basis weight offer ergonomic advantages for the appropriate cleaning task. For some cleaning tasks, the cleaning device may be square or square with rounded corners. For other cleaning tasks, the cleaning device may have a cleaning angle in the front to get into corners. For ergonomic use, the cleaning device may have a length greater than the width. For ergonomic use, the cleaning device may have a curved cleaning arc. For ergonomic reasons, the cleaning device may have a minimum thickness. For ergonomic reasons, the cleaning device may have a minimum basis weight. For ergonomic reasons, the cleaning device may have a minimum and maximum length. The cleaning device may also include on the attachment side an indicia that indicates the side for attachment to a cleaning implement.  
         [0054]     In order to ergonomically fit the cleaning task, the cleaning device has a desired cleaning shape, size and conformability. The cleaning device may have a ratio of length to width of greater than 1.0 and less than 1.5. The cleaning device may have a ratio of length to width of less than 1.25. The cleaning device may have a ratio of length to width of less than 1.1. The cleaning device may have a length between about 3 inches and about 7 inches. The cleaning device may have a length between about 4 inches and about 6 inches. The cleaning device may have a length between about 4.5 inches and about 5.5 inches. If the cleaning device has a cleaning arc, that cleaning arc may be greater than 1.5 inches. The cleaning device may have a cleaning arc greater than 2.0 inches. The cleaning device may have a cleaning arc greater than 2.5 inches. The cleaning device may have a cleaning arc greater than 3.0 inches. If the cleaning device has a cleaning angle, that cleaning angle can be between about 80 degrees and about 120 degrees. The cleaning device may have a cleaning angle of between about 90 degrees and about 115 degrees. The cleaning device should have a thickness greater than 0.3 inches. The cleaning device may have a thickness greater than 0.4 inches. The cleaning device may have a thickness greater than 0.5 inches. The cleaning device can have a basis weight greater than 200 gsm. The cleaning device may have a basis weight greater than 250 gsm. The cleaning device can have a basis weight greater than 300 gsm. The cleaning device can have a basis weight greater than 350 gsm. The cleaning device can have a basis weight greater than 400 gsm.  
         [0000]     Cleaning Device Structure  
         [0055]     In one embodiment, the inventive device can consist of a single layer of water-permeable material. In another embodiment, the device consists of two or more layers of material. The inventive device can comprise two layers, as shown in  FIG. 5 , the first layer  60  being water permeable and a second layer  61  being water permeable, impermeable or water-resistant. The second layer  61  is located between the first layer  60  and the cavity  62  formed by the device. By cavity is meant herein, the inner space provided by the device envelope shape to fit the user&#39;s hand and/or a mechanical device, as for example a brush, broom, or the like. The first layer  60  is the outer layer. The second layer  61  is the inner layer. In another embodiment, the device consists of three or more layers of material.  
         [0000]     Cleaning Device Substrate  
         [0056]     A wide variety of materials can be used as the cleaning device substrate. The substrate should have sufficient wet strength, abrasivity, loft and porosity. Examples of suitable substrates include, nonwoven substrates, wovens substrates, hydroentangled substrates, foams and sponges.  
         [0000]     Nonwoven Substrate  
         [0057]     In one embodiment, the cleaning device of the present invention comprises a nonwoven substrate or web. The substrate is composed of nonwoven fibers or paper. The term nonwoven is to be defined according to the commonly known definition provided by the “Nonwoven Fabrics Handbook” published by the Association of the Nonwoven Fabric Industry. A paper substrate is defined by EDANA (note 1 of ISO 9092-EN 29092) as a substrate comprising more than 50% by mass of its fibrous content is made up of fibers (excluding chemically digested vegetable fibers) with a length to diameter ratio of greater than 300, and can also have a density of less than 0.040 g/cm 3. The definitions of both nonwoven and paper substrates do not include woven fabric or cloth or sponge. The substrate can be partially or fully permeable to water. The substrate can be flexible and the substrate can be resilient, meaning that once applied external pressure has been removed the substrate regains its original shape.  
         [0058]     Methods of making nonwovens are well known in the art. Generally, these nonwovens can be made by air-laying, water-laying, meltblowing, coforming, spunbonding, or carding processes in which the fibers or filaments are first cut to desired lengths from long strands, passed into a water or air stream, and then deposited onto a screen through which the fiber-laden air or water is passed. The air-laying process is described in U.S. Pat. App. 2003/0036741 to Abba et al. and U.S. Pat. App. 2003/0118825 to Melius et al. The resulting layer, regardless of its method of production or composition, is then subjected to at least one of several types of bonding operations to anchor the individual fibers together to form a self-sustaining substrate. In the present invention the nonwoven substrate can be prepared by a variety of processes including, but not limited to, air-entanglement, hydroentanglement, thermal bonding, and combinations of these processes.  
         [0059]     Additionally, the first layer and the second layer, as well as additional layers, when present, can be bonded to one another in order to maintain the integrity of the article. The layers can be heat spot bonded together or using heat generated by ultrasonic sound waves. The bonding may be arranged such that geometric shapes and patterns, e.g. diamonds, circles, squares, etc. are created on the exterior surfaces of the layers and the resulting article.  
         [0060]     The bonding pattern can be chosen in order to maximize stiffness of the substrate. This applies when bonding is effected by adhesive (chemical, such as epoxy resin adhesive, or other adhesive) or by ultrasound. Thermal or pressure bonding can be used if the layers to be bonded are appropriate for this. One useful bonding pattern is application of adhesive or ultrasonic bonding across the full area of the substrate. Generally such patterns do not take up substantially the entire area, but generally not more than 20%, sometimes not more than 15%, but sometimes at least 5%, of the area of the substrate is covered by bonds.  
         [0061]     One suitable application pattern for adhesive, ultrasonic or other bonds is in the form of a number of stripes extending across the width of the substrate, for example, the stripes are parallel. The direction can be chosen depending upon the direction in which stiffness is required. For instance, if stiffness in the machine direction (this direction being defined in relation to the manufacturing process for the substrate) is required, i.e. it is required to make folding along a line extending in the transverse direction more difficult, then the stripes can extend in the machine direction. Conversely, if transverse direction stiffness is required, then stripes extending in the transverse direction can be provided. A suitable bonding pattern is one of two sets of parallel stripes at different angles, for instance in cross-hatch form. Such systems can provide the effect of introduction of a net between two layers.  
         [0062]     The above patterns for improvement of stiffness are useful when applied to adhesive or ultrasound bonding. However, such patterns can alternatively be applied using hot melt polymer printed onto the substrate, either between layers or on an exterior surface of one of the layers. Such patterns can be applied using any low melting polymer that is flexible after application and drying and capable of producing a continuous film. Suitable polymers include polyethylene. Application of hot melt polymer can be for instance by screen or gravure printing. Application of hot melt polymer can be on an exterior surface on one of the layers.  
         [0063]     Bonding can be effected after all layers intended to form the substrate have been assembled. In some embodiments, however, two or more layers can be pre-bonded prior to contacting these layers with additional layers to form the substrate.  
         [0064]     The stiffness of the substrate when wet is an important feature. Stiffness is expressed in Taber stiffness units, and can be measured in accordance with ASTM D-5650 (resistance to bending of paper of low bending stiffness). Stiffness of the substrate when dry is measured before it is used for cleaning a surface. Stiffness of the substrate when wet is measured after it has been saturated in water. Stiffness when dry can be at least 5, or at least 8 Taber stiffness units. In suitable cases, stiffness when dry is at least 9 Taber stiffness units. The Taber stiffness when wet can be at least 5 or at least 8. In suitable embodiments, the stiffness when wet can be at least 9 Taber stiffness units. Suitable embodiments have stiffness when wet at least 50% or at least 60% or at least 80% or at least 90% of stiffness when dry.  
         [0065]     The cleaning substrates can be provided dry, pre-moistened, or impregnated with cleaning composition, but dry-to the-touch. In one aspect, dry cleaning substrates can be provided with dry or substantially dry cleaning or disinfecting agents coated on or in the multicomponent multilobal fiber layer. In addition, the cleaning substrates can be provided in a pre-moistened and/or saturated condition. The wet cleaning substrates can be maintained over time in a sealable container such as, for example, within a bucket with an attachable lid, sealable plastic pouches or bags, canisters, jars, tubs and so forth. The use of a resealable container is suitable when using volatile liquid compositions since substantial amounts of liquid can evaporate while using the first substrates thereby leaving the remaining substrates with little or no liquid. Exemplary resealable containers and dispensers include, but are not limited to, those described in U.S. Pat. No. 4,171,047 to Doyle et al., U.S. Pat. No. 4,353,480 to McFadyen, U.S. Pat. No. 4,778,048 to Kaspar et al., U.S. Pat. No. 4,741,944 to Jackson et al., U.S. Pat. No. 5,595,786 to McBride et al.; the entire contents of each of the aforesaid references are incorporated herein by reference. The cleaning substrates can be incorporated or oriented in the container as desired and/or folded as desired in order to improve ease of use or removal as is known in the art. The cleaning substrates of the present invention can be provided in a kit form, wherein a plurality of cleaning substrates and a cleaning tool are provided in a single package.  
         [0066]     The substrate can include both natural and synthetic fibers. The substrate can also include water-soluble fibers or water-dispersible fibers, from polymers described herein. The substrate can be composed of suitable unmodified and/or modified naturally occurring fibers including cotton, Esparto grass, bagasse, hemp, flax, silk, wool, wood pulp, chemically modified wood pulp, jute, ethyl cellulose, and/or cellulose acetate. Various pulp fibers can be utilized including, but not limited to, thermomechanical pulp fibers, chemi-thermomechanical pulp fibers, chemi-mechanical pulp fibers, refiner mechanical pulp fibers, stone groundwood pulp fibers, peroxide mechanical pulp fibers and so forth.  
         [0067]     Suitable synthetic fibers can comprise fibers of one, or more, of polyvinyl chloride, polyvinyl fluoride, polytetrafluoroethylene, polyvinylidene chloride, polyacrylics such as ORLON®, polyvinyl acetate, Rayon®, polyethylvinyl acetate, non-soluble or soluble polyvinyl alcohol, polyolefins such as polyethylene (e.g., PULPEX®) and polypropylene, polyamides such as nylon, polyesters such as DACRON® or KODEL®, polyurethanes, polystyrenes, and the like, including fibers comprising polymers containing more than one monomer.  
         [0068]     The cleaning substrate of this invention may be a multilayer laminate and may be formed by a number of different techniques including but not limited to using adhesive, needle punching, ultrasonic bonding, thermal calendering and through-air bonding. Such a multilayer laminate may be an embodiment wherein some of the layers are spunbond and some meltblown such as a spunbond/meltblown/spunbond (SMS) laminate as disclosed in U.S. Pat. No. 4,041,203 to Brock et al. and U.S. Pat. No. 5,169,706 to Collier, et al., each hereby incorporated by reference. The SMS laminate may be made by sequentially depositing onto a moving conveyor belt or forming wire first a spunbond web layer, then a meltblown web layer and last another spunbond layer and then bonding the laminate in a manner described above. Alternatively, the three web layers may be made individually, collected in rolls and combined in a separate bonding step.  
         [0069]     The substrate can comprise solely naturally occurring fibers, solely synthetic fibers, or any compatible combination of naturally occurring and synthetic fibers.  
         [0070]     The fibers useful herein can be hydrophilic, hydrophobic or can be a combination of both hydrophilic and hydrophobic fibers. As indicated above, the particular selection of hydrophilic or hydrophobic fibers depends upon the other materials included in the absorbent (and to some degree) the scrubbing layer described hereinafter. Suitable hydrophilic fibers for use in the present invention include cellulosic fibers, modified cellulosic fibers, rayon, cotton, and polyester fibers, such as hydrophilic nylon (HYDROFIL®). Suitable hydrophilic fibers can also be obtained by hydrophilizing hydrophobic fibers, such as surfactant-treated or silica-treated thermoplastic fibers derived from, for example, polyolefins such as polyethylene or polypropylene, polyacrylics, polyamides, polystyrenes, polyurethanes and the like.  
         [0071]     Another type of hydrophilic fiber for use in the present invention is chemically stiffened cellulosic fibers. As used herein, the term “chemically stiffened cellulosic fibers” means cellulosic fibers that have been stiffened by chemical means to increase the stiffness of the fibers under both dry and aqueous conditions. Such means can include the addition of a chemical stiffening agent that, for example, coats and/or impregnates the fibers. Such means can also include the stiffening of the fibers by altering the chemical structure, e.g., by crosslinking polymer chains.  
         [0072]     Suitable thermoplastic fibers can be made from a single polymer (monocomponent fibers), or can be made from more than one polymer (e.g., bicomponent or multicomponent fibers). Multicomponent fibers are described in U.S. Pat. App. 2003/0106568 to Keck and Arnold. Bicomponent fibers are described in U.S. Pat. No. 6,613,704 to Arnold and Myers and references therein. Multicomponent fibers of a wide range of denier or dtex are described in U.S. Pat. App. 2002/0106478 to Hayase et. al.  
         [0073]     Suitable bicomponent fibers for use in the present invention can include sheath/core fibers having the following polymer combinations: polyethylene/polypropylene, polyethylvinyl acetate/polypropylene, polyethylene/polyester, polypropylene/polyester, copolyester/polyester, and the like. Suitable bicomponent thermoplastic fibers for use herein are those having a polypropylene or polyester core, and a lower melting copolyester, polyethylvinyl acetate or polyethylene sheath (e.g., those available from Danaklon a/s, Chisso Corp., and CELBOND®, available from Hercules). These bicomponent fibers can be concentric or eccentric. As used herein, the terms “concentric” and “eccentric” refer to whether the sheath has a thickness that is even, or uneven, through the cross-sectional area of the bicomponent fiber. Eccentric bicomponent fibers can be desirable in providing more compressive strength at lower fiber thicknesses.  
         [0074]     In one embodiment, the cleaning substrate has at least two regions where the regions are distinguished by basis weight. Briefly, the measurement is achieved photographically, by differentiating dark (low basis-weight) and light (high basis) network regions. For example, the cleaning substrate comprises one or more low basis weight regions, wherein the low basis region(s) have a basis weight that is not more than about 80% of the basis weight of the high basis weight regions. In one aspect, the first region is relatively high basis weight and comprises an essentially continuous network. The second region comprises a plurality of mutually discrete regions of relatively low basis weight and which are circumscribed by the high basis weight first region. For example, a cleaning substrate may comprise a continuous region having a basis weight of from about 30 to about 120 grams per square meter and a plurality of discontinuous regions circumscribed by the high basis weight region, wherein the discontinuous regions are disposed in a random, repeating pattern and having a basis weight of not more than about 80% of the basis weight of the continuous region.  
         [0075]     The substrate may also contain superabsorbent materials. A wide variety of high absorbency materials (also known as superabsorbent materials) are known to those skilled in the art. See, for example, U.S. Pat. No. 4,076,663 issued Feb. 28, 1978 to Masuda et al, U.S. Pat. No. 4,286,082 issued Aug. 25, 1981 to Tsubakimoto et al., U.S. Pat. No. 4,062,817 issued Dec. 13, 1977 to Westerman, and U.S. Pat. No. 4,340,706 issued Jul. 20, 1982 to Obayashi et al. The absorbent capacity of such high-absorbency materials is generally many times greater than the absorbent capacity of fibrous materials. For example, a fibrous matrix of wood pulp fluff can absorb about 7-9 grams of a liquid, (such as 0.9 weight percent saline) per gram of wood pulp fluff, while the high-absorbency materials can absorb at least about 15, or at least about 20, or at least about 25 grams of liquid, such as 0.9 weight percent saline, per gram of the high-absorbency material. U.S. Pat. No. 5,601,542, issued to Melius et al., discloses an absorbent article in which superabsorbent material is contained in layers of discrete pouches. Alternately, the superabsorbent material may be within one layer or dispersed throughout the substrate.  
         [0000]     Cleaning Device Properties  
         [0076]     The cleaning device may show minimal migration of the cleaning composition during storage. The cleaning device may comprise 100% thermoplastic fibers or 100% of the same thermoplastic fiber type in order to allow the more convenient bonding of layers. The cleaning device may also comprise some non-thermoplastic fibers, such as cellulosic fibers. The cleaning device should allow the cleaning composition to be used up after use on one to two tasks, for example one to two showers. One example of an indication of no more cleaning composition is the absence of foam. The cleaning device may change color as the soap is used up. The cleaning device may acquire a dirty appearance or may start to come apart in order to indicate that it should be disposed. The cleaning device may not be so thick that the consumer considers the device not to be disposable.  
         [0000]     Cleaning Composition  
         [0077]     In one embodiment, the cleaning device is impregnated with a cleaning composition and is ‘wet-to-the-touch’. In another embodiment, the cleaning device is impregnated with a cleaning composition that is ‘dry-to-the-touch’. By ‘dry-to-the-touch’, it is meant that the substrate is free of water or other solvents in an amount that would make them feel damp or wet-to-the-touch as compared to the touch of a wet substrate. In another embodiment, the cleaning device is free of the cleaning composition.  
         [0078]     The cleaning composition may contain one or more surfactants selected from anionic, nonionic, cationic, ampholytic, amphoteric and zwitterionic surfactants and mixtures thereof. A typical listing of anionic, nonionic, ampholytic, and zwitterionic classes, and species of these surfactants, is given in U.S. Pat. No. 3,929,678 to Laughlin and Heuring. A list of suitable cationic surfactants is given in U.S. Pat. No. 4,259,217 to Murphy. Where present, ampholytic, amphotenic and zwitteronic surfactants are generally used in combination with one or more anionic and/or nonionic surfactants. The surfactants may be present at a level of from about 0% to 90%, or from about 0.001% to 50%, or from about 0.01% to 25% by weight.  
         [0000]     Solvent  
         [0079]     Suitable organic solvents include, but are not limited to, C 1-6  alkanols, C 1-6  diols, C 1-10  alkyl ethers of alkylene glycols, C 3-24  alkylene glycol ethers, polyalkylene glycols, short chain carboxylic acids, short chain esters, isoparafinic hydrocarbons, mineral spirits, alkylaromatics, terpenes, terpene derivatives, terpenoids, terpenoid derivatives, formaldehyde, and pyrrolidones. The solvents can present at a level of from 0.001% to 10%, or from 0.01% to 10%, or from 1% to 4% by weight.  
         [0000]     Additional Adjuncts  
         [0080]     The cleaning compositions optionally contain one or more of the following adjuncts: stain and soil repellants, lubricants, odor control agents, perfumes, fragrances and fragrance release agents, and bleaching agents. Other adjuncts include, but are not limited to, acids, electrolytes, dyes and/or colorants, solubilizing materials, stabilizers, thickeners, defoamers, hydrotropes, cloud point modifiers, preservatives, and other polymers. The solubilizing materials, when used, include, but are not limited to, hydrotropes (e.g. water soluble salts of low molecular weight organic acids such as the sodium and/or potassium salts of toluene, cumene, and xylene sulfonic acid). The acids, when used, include, but are not limited to, organic hydroxy acids, citric acids, keto acid, and the like. Electrolytes, when used, include, calcium, sodium and potassium chloride. Thickeners, when used, include, but are not limited to, polyacrylic acid, xanthan gum, calcium carbonate, aluminum oxide, alginates, guar gum, methyl, ethyl, clays, and/or propyl hydroxycelluloses.

Bleaching agents, when used, include, but are not limited to, peracids, hypohalite sources, hydrogen peroxide, and/or sources of hydrogen peroxide. Bleaching agents may be present in concentrations of 0.001% up to 100% of the cleaning composition.  
         [0000]     Antimicrobial Agent  
         [0081]     The cleaning compositions may contain antimicrobial agents. Antimicrobial agents include quaternary ammonium compounds and phenolics. Non-limiting examples of these quaternary compounds include benzalkonium chlorides and/or substituted benzalkonium chlorides, di(C 6 -C 14 )alkyl di short chain (C 1-4  alkyl and/or hydroxyalkl) quaternary ammonium salts, N-(3-chloroallyl)hexaminium chlorides, benzethonium chloride, methylbenzethonium chloride, and cetylpyridinium chloride. Other quaternary compounds include the group consisting of dialkyldimethyl ammonium chlorides, alkyl dimethylbenzylammonium chlorides, dialkylmethylbenzylammonium chlorides, and mixtures thereof. Biguanide antimicrobial actives including, but not limited to polyhexamethylene biguanide hydrochloride, p-chlorophenyl biguanide; 4-chlorobenzhydryl biguanide, halogenated hexidine such as, but not limited to, chlorhexidine (1,1′-hexamethylene -bis-5-(4-chlorophenyl biguanide) and its salts are also in this class.  
         [0000]     Builder/Buffer  
         [0082]     The cleaning composition may include a builder or buffer, which increase the effectiveness of the surfactant. The builder or buffer can also function as a softener and/or a sequestering agent in the cleaning composition. A variety of builders or buffers can be used and they include, but are not limited to, phosphate-silicate compounds, zeolites, alkali metal, ammonium and substituted ammonium polyacetates, trialkali salts of nitrilotriacetic acid, carboxylates, polycarboxylates, carbonates, bicarbonates, polyphosphates, aminopolycarboxylates, polyhydroxysulfonates, and starch derivatives. When employed, the builder, buffer, or pH adjusting agent comprises at least about 0.001% and typically about 0.01-5% of the cleaning composition. The builder or buffer content can be about 0.01-2%.  
         [0000]     Effervescence  
         [0083]     The cleaning composition may comprise materials that effervesce when combined with water. The materials may be within a water-soluble, water-insoluble, or water-dispersible pouch to slow the effervescent action or to protect the composition from premature hydration. The materials may comprise a polymeric agent to slow the effervescence. One component of the effervescent materials may be an acidic material. Suitable for this purpose are any acids present in dry solid form. Suitable for this purpose are C 2-20  organic mono- and poly-carboxylic acids such as alpha- and beta-hydroxycarboxylic acids; C2-20 organophosphorus acids such as phytic acid; C2-20 organosulfur acids such as toluene sulfonic acid; and peroxides such as hydrogen peroxide or materials that generate hydrogen peroxide in solution. Typical hydroxycarboxylic acids include adipic, glutaric, succinic, tartaric, malic, maleic, lactic, salicylic and citric acids as well as acid forming lactones such as gluconolactone and gluccrolactone. A suitable acid is citric acid. Also suitable as acid material may be encapsulated acids. Typical encapsulating material may include water-soluble synthetic or natural polymers such as polyacrylates (e.g. encapsulating polyacrylic acid), cellulosic gums, polyurethane and polyoxyalkylene polymers. By the term “acid” is meant any substance which when dissolved in deionized water at 1% concentration will have a pH of less than 7. These acids may also have a pH of less than 6.5 or less than 5. These acids may be at 25° C. in solid form, i.e. having melting points greater than 25° C. Concentrations of the acid should range from about 0.5 to about 80%, or from about 10 to about 65%, or from about 20 to about 45% by weight of the total composition.  
         [0084]     Another component of the effervescent materials may be a alkaline material. The alkaline material may a substance that can generate a gas such as carbon dioxide, nitrogen or oxygen, i.e. effervesce, when contacted with water and the acidic material. Suitable alkaline materials are anhydrous salts of carbonates and bicarbonates, alkaline peroxides (e.g. sodium perborate and sodium percarbonate) and azides (e.g. sodium azide). An example of the alkaline material is sodium or potassium bicarbonate. Amounts of the alkaline material may range from about 1 to about 80%, or from about 5 to about 49%, or from about 15 to about 40%, or from about 25 to about 35% by weight of the total composition.  
         [0085]     When the cleaning composition comprises effervescent materials, then the composition may comprise no more than 5%, or no more than 3.5%, or no more than 1% water by weight of the total composition. Water of hydration is not considered to be water for purposes of this calculation. However, water of hydration can be present. The combined amount of acidic and alkaline materials may be greater than 1.5%, or from about 40 to about 95%, or from about 60 to about 80% by weight of the total composition.

         [0111]     In one example, a substrate (Example AA) was prepared by glue lamination of three nonwoven-layers. The surface scrubbing layer was formed from needle punched polypropylene (25%-18 denier, 30% 1.5 denier, 45% 3 denier) with a singe finish and reinforced with spunbond 10 gsm polypropylene. The total basis weight of the surface scrubbing layer was 100 gsm. The middle reservoir layer consisted of a 4 layer ultrasonically bonded structure (top and bottom layers—polyester (6, 9 denier), carded web forming with chemical bonding, 78 gsm; middle two layers—polypropylene (2 denier), spunbond, 75 gsm). The total basis weight of the middle reservoir layer was 313 gsm. The bottom layer consisted of bicomponent fiber (polyethylene/polyester (3,6 denier)) made by carded web forming, through air bonded. The total basis weight of the bottom layer was 146 gsm. The cleaning device can be formed by laminating two substrate layers together or may form an interior cavity between any substrate layers. The cleaning device can be directly attached to a cleaning implement or attached first to a fitment and then to a cleaning implement. The substrate was tested for capacity to hold the cleaning composition and the results are given in Table IV.
