Cleaning product for storing and attaching cleaning blocks or wipes
An apparatus for storing and attaching cleaning wipes or cleaning blocks is provided. The apparatus includes a container configured for holding at least one cleaning wipe or block. The container has a body with an attaching surface. An attachment mechanism is included and is configured for attaching the cleaning wipe or block to the attaching surface for use in a cleaning procedure. The container is capable of being grasped to aid in positioning of the cleaning wipe or block during the cleaning procedure.
Cleaning applications employ cleaning products, such as towels, in order to remove dirt and other unwanted elements from surfaces. In some instances the cleaning product may be a urethane foam or a cellulose sponge which may be used in order to wipe a surface clean. The cleaning product may be configured with bristles or grit disposed thereon in order to aid in cleaning.
Cleaning products can be configured to work when in a dry state in order to clean the surface, or may be designed to work in a wet state so that the cleaning product is wet to some degree when cleaning the surface. A detergent may be used with the cleaning product in order to assist in breaking up dirt and other unwanted elements so that the surface may be cleaned. It is sometimes the case that dirt or other unwanted elements cannot be sufficiently removed from a surface even when a cleaning product is properly applied. Applying the cleaning product too aggressively may result in the surface being damaged, and may still not result in the removal of dirt or unwanted elements from the surface. Examples of difficult to clean materials include crayon on walls, scuff marks from shoes on floors, permanent magic marker markings on a variety of surfaces such as dry erase boards, stains on porcelain or ceramics including dentures, grease and oil spots on numerous surfaces, hard water spots and soap scum on tile, biofilms on metal and plastic surfaces, mildew and fungus growths on numerous surfaces, and other forms of dirt, grime, or other unwanted elements from various surfaces.
Melamine-based foam has been recognized as having useful cleaning properties when wetted with water and rubbed against certain surfaces to be cleaned, and have been marketed in several countries for such purposes. Melamine-based foam has an open-celled, microporous structure. Melamine-based foam is abrasive in that when rubbed across a surface, dirt and other unwanted elements will be removed. Particles of the melamine-based foam may break off due to this abrasive contact. Over time, the melamine-based foam will be worn down due to repeated abrasion with the surface to be cleaned and the unwanted elements present on this surface.
Melamine-based foam may be used to clean a surface when in a wet state. In this regard, the melamine-based foam may be soaked with water to some degree prior to being applied by a user to the surface to be cleaned. A block of melamine-based foam by itself is sometimes used as a cleaning product. In this regard, the user may grasp the block of melamine-based foam, wet the block in water, and then rub the wetted melamine-based foam across a surface to remove dirt and unwanted elements.
Alternatively, a cleaning wipe may be provided that includes a layer of melamine-based foam attached to a backing layer such as a web for use in cleaning a surface. The web may be a non-woven web and the melamine-based foam may be attached to the web in a variety of manners, for instance the melamine-based foam may be laminated to the web. Additionally, multiple layers of melamine-based foam and web backing may be provided to achieve various functionality such as allowing for the replacement of a worn out sheet of melamine-based foam and web backing. Further, cleaning wipes may be provided that employ other relatively brittle foams such as phenolic foams. Still further, cleaning wipes are in use that do not incorporate any type of foam therein.
Cleaning products such as blocks and cleaning wipes, including those that incorporate melamine-based foam, suffer from excessive and nonuniform wear at a few pressure points where the fingers of the user selectively depress the product when in use. Due to nonuniform wear, a user may prematurely discard the product even though other portions of the product have experienced little wear or are unused. At such time, the user will have to travel to a second location to retrieve a new cleaning product to continue cleaning.
Another problem exists when the user selectively depresses only certain portions of a cleaning product. For instance, if a cleaning wipe that incorporates a melamine-based foam was applied to remove a crayon mark, the fingers of the user will apply pressure to the foam in the vicinity of the mark. After removal, crayon will be plainly visible in a highly soiled, isolated spot on the foam. This allows for the possibility of secondary transfer of the crayon to a previously unsoiled clean surface, the hands of the user, or to another soiled surface that is to be cleaned.
The present invention improves upon known cleaning products by providing for a cleaning product that acts as both a storage container for cleaning blocks or wipes and as a gripping member that is capable of holding the blocks or wipes during cleaning. A user may grasp the cleaning product and move the cleaning block or wipe over a surface in a uniform manner that provides for more uniform wear and soiling of the block or wipe due to the backing action provided by the cleaning product. Application of uniform pressure allows for the unwanted material to be more uniformly spread over the cleaning block or foam such that it is less visible. Cleaning with uniform pressure extends the life of the cleaning block or wipe, improves comfort, decreases soiling or wetting of the hands, and improves convenience.
Additionally, the ability of the cleaning product to store cleaning blocks or wipes allows for the user to continue cleaning without having to move to a separate location to retrieve a new cleaning block or wipe. Also, the user will be able to ascertain the exact amount of cleaning blocks or wipes available for use during cleaning since the cleaning products are stored on hand. This feature increases convenience and allows for a decrease in the amount of time spent cleaning.

The cleaning product 10 may be configured in a variety of manners in accordance with various exemplary embodiments of the present invention.
Lid 22 is attached to body 14 by way of a snap-fit connection 27. Snap-fit connection 27 includes four male snap-fit members 28 located on lid 22 that are received in complementary female snap-fit members 30 on body 14. Although shown using four male snap-fit members 28 and four female snap-fit members 30, it is to be understood that in accordance with various exemplary embodiments of the present invention fewer or more of these members 28, 30 may be employed in order to effect attachment of lid 22 to body 14. The construction of such a snap-fit connection 27 is well known to one of ordinary skill in the art, and it is to be understood that the present invention includes various modifications to the shape, size, and configuration of the male and female snap-fit members 28, 30 as is known in the art.
Attachment mechanism 24 may be an adhesive 86 as shown in
In order to aid in retaining lid 22 in the closed position, a hook and loop type fastener 32 is employed on one end of lid 22 and body 14. Hook and loop type fastener 32 includes a plurality of hooks 34 attached to the underside of lid 22 that are configured to engage and be retained by a plurality of loops 36 attached to an upper portion of body 14. Such hook and loop type fasteners 32 are well known in the art, and the hook and loop type fastener 32 employed can be variously configured in accordance with other exemplary embodiments of the present invention. For instance, the loops 36 may be positioned on lid 22 and the hooks 34 may be positioned on body 14 in a different embodiment of cleaning product 10. Hook and loop type fastener 32 may be selected so as to open upon the application of a predetermined and desired force.
The cleaning product 10 in
The attaching surface 20 may be of any size or shape, although the attaching surface 20 may be preferably flat in certain exemplary embodiments in order to assist in providing for uniform wiping of the cleaning wipe 18.
Referring back to
Lid 22 and container 12 may be made out of any suitable material. For instance, these components may be made out of plastic or rubber in accordance with certain exemplary embodiments. When closed, lid 22 may form a watertight seal in order to prevent liquid from escaping or entering interior space 16. This feature may be beneficial when the cleaning wipes 18 are provided in a moist state. In this case, the watertight seal of lid 22 will prevent the cleaning wipes 18 from prematurely drying out and will in turn extend the life of the cleaning wipes 18. Additionally, should the cleaning wipes 18 be provided in a dry state, the lid 22 and possibly the watertight seal will prevent premature wetting of the cleaning wipes 18 in the interior space 16 again extending the life of cleaning wipes 18.
Cleaning product 10 may be formed in a variety of configurations having various sizes and shapes.
Although described as having an interior space 16 into which cleaning wipes 18 are positioned, cleaning product 10 may be configured in order to hold cleaning wipes 18 on the exterior of body 14 such that a lid 22 is not necessary. This type of positioning will eliminate the need of having a user open lid 22 and insert his or her hand into the body 14 in order to retrieve a fresh cleaning wipe 18.
Attachment mechanism 24 may be configured in a variety of manners in order to attach cleaning wipe 18 to attaching surface 20.
The hook and loop type fastener 58 used in order to attach cleaning wipe 18 to attaching surface 20 may be made under the brand name VELCRO®. One example of a type of VELCRO® material that may be used in accordance with one exemplary embodiment of the present invention may be manufactured by Velcro USA, Inc. located at 406 Brown Avenue, Manchester, N.H. 03103.
The gecko-type fasteners 64 mimic the adhesive characteristics of gecko feet. Principles of gecko adhesion are discussed in more detail in Kelly Autumn et al., “Evidence for van der Waals Adhesion in Gecko Setae,” Proceedings of the National Academy of Sciences of the United States of America, Vol. 99, No. 19, pp. 12,252-12,256 (Sep. 17, 2002); in Robert J. Full et al., “Adhesive Microstructure and Method of Forming the Same,” WO 01/49776, published Jul. 12, 2001; in U.S. application Ser. No. 10/039574, “Adhesive Microstructure and Method of Forming Same,” filed Jan. 2, 2002 by K. Autumn and published as US20030124312-A1 on Jul. 3, 2003; and in U.S. application Ser. No. 10/197763, “Adhesive Microstructure and Method of Forming Same,” filed Jul. 17, 2002 by R. Fearing and published as US 20030208888-A1 on Nov. 13, 2003; all of which are incorporated by reference herein in their entireties. In general, gecko-like materials can have a plurality of microscopic protrusions rising from a surface, the protrusions having a diameter of about 0.1 to 1 microns and a height of about 0.5 microns to about 500 microns, said protrusions being effective at adhering to an opposing surface without the use of pressure-sensitive adhesives.
In accordance with the various configurations of attachment mechanism 24, strong attachment of the cleaning wipe 18 to attaching surface 20 is not needed in order to enable cleaning product 10 to function. However, the peel force for removal of the cleaning wipe 18 from attaching surface 20 may be desirably low in accordance with certain exemplary embodiments of the present invention in order to facilitate repeated removal and reattachment of a fresh cleaning wipe 18. It is generally desirable for the cleaning wipe 18 to have good shear resistance so that the cleaning wipe 18 does not readily detach under shear forces subjected thereon typically produced by scrubbing with the cleaning product 10.
Other cleaning components may be incorporated into cleaning product 10 in accordance with other exemplary embodiments of the present invention.

Examples of cleaning wipes 18 or cleaning blocks 92 that may be used in accordance with the present invention may be found, for instance, in U.S. patent application Ser. No. 10/744,238, filed on Dec. 22, 2003, whose inventors are Jeff Lindsay, Fung-Jou Chen, Julie Bednarz, Stan Kellenberger, and James Tanner, entitled “Multipurpose Cleaning Product Including A Foam and A Web.” The entire disclosure of U.S. patent application Ser. No. 10/744,238 is incorporated by reference herein in its entirety for all purposes. Other examples of how the cleaning wipes 18 may be configured are as that shown in U.S. patent application Ser. No. 10/321,277, filed Dec. 17, 2002, whose inventors are Fung-Jou Chen and Jeff Lindsay, entitled “Disposable Scrubbing Product.” The entire disclosure of U.S. patent application Ser. No. 10/321,277 is incorporated by reference herein in its entirety for all purposes.
The cleaning wipe 18 includes a foam such as a melamine-based foam 90 that is attached to a web 88. The foam 90 generally has an open celled structure that when moved over a surface is capable of effectively cleaning dirt and other unwanted elements from the surface. The web 88 may act as a reinforcing layer in order to strengthen or hold the melamine based foam 90, and/or may provide for water retaining properties which help to keep the melamine based foam 90 wet should wet wiping with the cleaning wipe 18 on attaching surface 20 be conducted. Alternatively or in addition, the web 88 may be adapted for scrubbing, and may comprise abrasive material (not shown) such as coarse polymeric filaments, meltblown shot, abrasive particles, hook-like protrusions such as those used in hook and loop mechanical fastening systems, and the like.
The web 88 may comprise a structure of fibers or filaments that are retained to one another by fiber-fiber bonding (e.g., hydrogen bonding), fiber entanglement, adhesive bonding, interfiber or interfilament friction, and the like. In accordance with one exemplary embodiment of the present invention, the web 88 can be a hydrophilic cellulosic fibrous web such as a wet-laid or air-laid paper web comprising predominately natural cellulosic fibers such as wood-based papermaking fibers, cotton, kenaf, bagasse, milkweed, etc., and mixtures thereof In other embodiments, the web 88 may be a paper web comprising synthetic cellulosic fibers such as rayon. Alternatively, the web 88 can be a nonwoven fibrous web which has a structure of individual fibers or threads which are interlaid, but not in an identifiable manner as in a knitted fabric. The fibers in a nonwoven web are generally understood to be manmade fibers such as non-cellulosic polymeric fibers, typically based on synthetic polymers such as polyolefins, including webs made from meltspun processes (meltblowing, spinbonding, etc.). Alternatively, the web 88 need not include a fiber structure but may be, for instance, a film or foam in other exemplary embodiments.
The foam 90 may be laminated to the web 88 in order to effect attachment of these two components of the cleaning wipe 18. The term “laminated” as used herein means the two components are united to one another by an adhesive optionally with the use of heat and/or pressure. However, in accordance with other exemplary embodiments of the present invention, the foam 90 may be attached to the web 88 in a variety of manners. For instance, these two components may be attached to one another by ultrasonic bonding, hot melts, pressure sensitive adhesives, thermal bonds, or by mechanical attachments such as sewing, mechanical fasteners, or a hook and loop type fastener in accordance with other exemplary embodiments. Hydroentangling can also be used to join a fibrous web to the foam. In one embodiment, a hotmelt is used comprising at least one polymer with a substantial number of carboxyl groups or salts thereof to provide good bonding with a fibrous cellulosic web when wet. For example, a hot melt suitable for the present invention may comprise ethylene vinyl acetate (EVA), and may have at least about 20 weight percent (wt %) EVA or at least about 50 wt % EVA. Hotmelts may be applied by meltblown nozzles, glue guns, other known adhesive nozzles, and the like. After hotmelt is applied to one or both surfaces to be joined, the two surfaces can immediately be brought into contact and optionally pressed together with a compressive force, such as a force of about 0.03 psi or greater, or about 0.5 psi or greater, or about 5 psi or greater. The compressive force may be provided by a nip between two rollers, pressure between two flat plates, or other methods known in the art.
The cleaning wipe 18 may be configured such that the foam 90 is a relatively thin layer. For instance, the foam may be on the order of from about 2 millimeters to about 8 millimeters in thickness. Other exemplary embodiments of the present invention exists in which the foam 90 may have a varying thickness, for instance being 1 millimeter thick at certain portions of the web 88, and being 10 millimeters thick at other portions of the web 88. As such, the present invention includes various embodiments in which the foam 90 has a uniform thickness throughout, and also a varying thickness throughout. Additionally, the present invention includes exemplary embodiments where the foam 90 is less than 20 millimeters in thickness. Still further exemplary embodiments exist in which the foam 90 is less than 15 millimeters in thickness, less than 10 millimeters in thickness, and less than 5 millimeters in thickness. Additional exemplary embodiments of the present invention exist in which the foam 90 is from about 1 millimeter to about 15 millimeters in thickness.
The web 88 may be made of a soft material so that it is capable of buffing or polishing a surface. Alternatively, the web 88 may be made of a coarse material such that the web 88 is more coarse or abrasive than the foam 90. In this instance, the cleaning wipe 18 may be used so that the web 88 is capable of scrubbing coarse surfaces which would otherwise damage the foam 90. In fact, the web 88 may be more capable of removing dried food substances or ground in dirt and some other unwanted elements from a surface to be cleaned in other exemplary embodiments. The web 88 may comprise abrasive grit or meltblown shot joined to a fibrous substrate, or abrasive fibers such as the multifilamentary aggregates disclosed in commonly owned U.S. patent Ser. No. 10/321,831, “Meltblown Scrubbing Product,” filed Dec. 17, 2002 by Chen et al., herein incorporated by reference. A portion of the cleaning surface of the foam 90 itself may also be joined to materials such as meltblown shot or multifilamentary aggregates, in order to enhance cleaning or to strengthen the foam 90 and prevent the foam 90 from being damaged during cleaning.
The web 88 may optionally include an abrasive material disposed therein, such as a coarse meltblown shot, an abrasive grit such as mineral particles, or a meltblown multifilamentary aggregate.
The cleaning wipe 18 may be incorporated into a scrubbing pad that is attached to attaching surface 20 such that cleaning wipe 18 is attached to attaching surface 20. Here, the cleaning wipe 18 comprises the outer surface of the scrubbing pad. The foam 90 is located on one end of the scrubbing pad. Alternatively, the foam 90 may be included on both ends of the scrubbing pad in accordance with other exemplary embodiments. The web 88 is again attached to the foam 90.
The scrubbing pad may be a layered structure, the outer layer being the cleaning wipe 18. Additional layers of the scrubbing pad may be each an abrasive meltblown layer which is also capable of contacting a surface to be cleaned once the cleaning wipe 18 is removed. The abrasive layer may be attached to a water absorbent substrate, which may be for instance a sponge. In this exemplary embodiment of the present invention, the scrubbing pad may be configured to clean a surface when the scrubbing pad is wet to some degree.
Once the cleaning wipe 18 has been worn down to some degree, the abrasive layer or layers may be exposed in order to assist in cleaning the surface to be cleaned. Although described as being an abrasive meltblown, the layers may be substituted for additional cleaning wipes 18 in accordance with other exemplary embodiments of the present invention.
In an alternative exemplary embodiment, the cleaning wipe 18 may be incorporated into a sponge substitute. The sponge substitute used may be that as described in U.S. Ser. No. 10/036,736 filed on Dec. 21, 2001 which published as U.S. patent application publication No. U.S. 2003/0,135,181 on Jul. 17, 2003. This application is owned by the assignee of the present application and is incorporated by reference herein in its entirety for all purposes. The cleaning wipe 18 may cover one side of the sponge substitute. Attachment of the sponge substitute to attaching surface 20 causes cleaning wipe 18 to be attached to attaching surface 20.
The cleaning wipe 18 may also be configured to include alternating layers of foam 90 and web 88 joined together. The alternating layers of foam 90 and web 88 are configured into a stack. In such a configuration, use of the cleaning product 10 with cleaning wipe 18 will eventually result in one of the layers of the foam 90 and/or the web 88 to be worn away. In such an instance, a fresh layer of foam 90 and/or web 88 will be exposed upon the wearing away of the preceding foam 90 and/or web 88.
The foam 90 may extend across the entire surface of the web 88, or the foam 90 may extend only over a portion of the surface of the web 88. In accordance with other exemplary embodiments of the present invention, any number of additional pieces of foam 90 may be placed onto the web 88 such that a plurality of foam 90 pieces are located throughout the receiving surface of the web 88.
In accordance with one exemplary embodiment of the present invention, the foam 90 and the web 88 are attached to one another due to the fact that the foam 90 and the web 88 are integrally formed with one another. The entire foam 90 or a layer or portion of the foam 90 may be integrally formed with a plurality of fibers. The plurality of fibers may be paper making fibers, mineral fibers, and/or polymeric fibers. The foam 90 may be integrally formed with the plurality of fibers which form the web 88 of the cleaning wipe by a method as set forth in U.S. Pat. No. 6,603,054 which is owned by the assignee of the present invention and is incorporated herein for all purposes in its entirety. In one such instance, the web 88 may be dispersed throughout the foam 90 and therefore integrally connected therewith. Here, about 10% or more of the weight of the cleaning wipe 18 may be from the plurality of fibers which are formed by blending loose fibers into a resin coupled with a blowing agent or other foam-producing means prior to curing the resin in order to form the foam.
The web 88 may in other exemplary embodiments of the present invention be provided with additional functionality. For instance, web 88 may be provided with a plurality of functional members disposed therein. The functional members may be cleaning agents in order to help aid the cleaning wipe 18 in cleaning a surface. For instance, the functional members may be enzymes such as papain enzymes, or may be bleaching agents such as peroxide. Additionally, the functional members may be abrasive compounds or may be detergents in accordance with other exemplary embodiments. The functional members may also be configured such that they release an odor which may subsequently be transferred to the surface which is to be cleaned. Further, the functional members may be skin wellness agents. The functional members may be encapsulated in a polymeric or lipid shell capable of breaking during use in response to mechanical compression and shear, whereby ingredients in the functional members are released. Alternatively, the functional members may be encased or encapsulated in a water soluble material such that solvation of the material when wet permits release of the functional components. The functional members may be antimicrobial agents and/or natural plant based extracts or compounds in accordance with other exemplary embodiments. The functional members may be a detergent, a bleaching agent, a solvent, enzymes, etc.
The cleaning product 10 may also have an added functionality such that the container 12 and/or the functional members act as a biosensor. In this instance, should the cleaning wipe 18 and/or the functional members detect the presence of harmful bacteria, lead, mercury, or other agents, the cleaning wipe 18 and/or functional member may change color in order to indicate the presence of such agents. Alternatively or additionally, the cleaning wipe 18 and/or functional members may be heat generating agents, for instance the cleaning wipe 18 may employ thermal pad technology. In one instance, oxidation of iron may result in a heating of the cleaning wipe 18. Alternatively, water activated technology may be used, such as calcium chloride pellets, in order to heat the cleaning wipe 18 such that the cleaning wipe 18 is also heated. Heating of the cleaning wipe 18 may be advantageous in that more effective cleaning of grease or other elements may be realized when employing the cleaning product 10.
The functional members may be odor control agents such as cyclodextrins, zeolites, clays, and/or activated carbon particles or fibers. The cleaning wipe 18 may also be configured to have a chemical agent in order to combat odor or to regulate the release of odor eliminating or odor providing compounds. Chemical agents which may be included are, for instance, chlorine dioxide, antimicrobial gases or liquids, time release antimicrobial compounds, silver ions embedded in the foam 90, zeolites, and/or chitosan-related compounds.
The cleaning wipe 18 and/or functional members may also be foaming agents. In these instances, the foaming agents may be activated when contacted by water in order to create a foam which may additionally be used in helping the cleaning wipe 18 clean a surface of dirt or other unwanted elements. Also, the functional members and/or the web 88 may be made of a material or configured in order to help keep the foam 90 wet during use of the cleaning wipe 18.
Although described as being incorporated into the web 88, the functional members may be incorporated into the foam 90 of the cleaning wipe 18 in accordance with other various embodiments. Further, the functional members may be on the outer surface, edges, or even separate from the web 88 and/or foam 90.
The cleaning product 10 may be employed by a user in order to clean the face or other portions of the user's body. The cleaning product 10 may also be used as a make-up removal article. In this instance, the foam 90 may be provided with extra pore space in order to catch and hold make-up during wiping by the user across the surface of the skin. In such an instance, the foam 90 of the cleaning wipe 18 may provide a soft yet abrasive cleaning of the skin of the user. Such cleaning may be either wet or dry. Extra pore space may be provided by needling, drilling, laser drilling, punching, aperturing, or other means to provide wells or other depressions suitable for retaining removed material.

One or more portions of the cleaning wipe 18, for instance the foam 90 and/or the web 88, may be charged in order to more effectively remove and retain bacteria. In accordance with one exemplary embodiment, the foam 90 and/or the web 88 have an electrostatic charge either chemically, or by the addition of electrets in order to help attract and retain bacteria by electrostatic means. A chemical electrostatic charge may be provided, for instance, by chitosan, polyvinylamines, primary, secondary, tertiary, or quaternary amines, cationic polymers, polyelectrolytes.
Any known method may be used for adding charged compounds to the surfaces of the struts in the foam 90 should charged surfaces be desired in the cleaning foam 90. For example, chemical additives may be attached to the surface of the polymeric struts by impregnating the foam 90 with a solution containing charged species that can be cross linked to each other or to the foam 90. Combinations of chemical, electrical, and other physical treatments may be used, such as plasma treatment, corona discharge treatment, electret generation, and the like. By way of example, chemical post-treatments of hydrophobic surface are disclosed in U.S. Pat. No. 6,537,614, issued Mar. 25, 2003 to N. Wei et al., and it is believed that such treatments can be adapted for the cleaning foams 90 of the present application. The Wei et al. patent discloses a hydrophobic polymer fiber having a cationically charged coating thereon, in which the coating includes a functionalized cationic polymer, such as an epichlorohydrin-functionalized polyamine or an epichlorohydrin-functionalized polyamido-amine, which has been crosslinked by heat. Such materials can be made by treating the fibrous filter with an aqueous solution of a functionalized cationic polymer cross linkable by heat under conditions sufficient to substantially coat the fibers with the functionalized cationic polymer, wherein the solution includes the functionalized cationic polymer, a poly(vinyl alcohol), a polar solvent for the poly(vinyl alcohol), and water; and treating the resulting coated fibrous filter with heat at a temperature and for a time sufficient to crosslink the functionalized cationic polymer present on the hydrophobic polymer fibers. As adapted for the present application, a solution of a functionalized cationic polymer cross linkable by heat can be used to impregnate or saturate all or a portion of a cleaning foam 90 layer to coat the struts of the foam 90. The resulting coated foam 90 can be treated with heat at a temperature and for a time sufficient to crosslink the functionalized cationic polymer present on the surfaces of the foam 90.
The cleaning wipe 18 may also be configured in some embodiments such that the “melamine based foam” 90 is a non-melamine foam that contains melamine powder.
Further, any aminoplast foam or other rigid or brittle foam disclosed in U.S. Pat. No. 4,125,664, “Shaped Articles of Foam Plastics,” issued Nov. 14, 1978 to H. Giesemann, herein incorporated by reference, may be used with the cleaning product 10 of the present invention. Other foams 90 believed to be useful within the scope of the present invention include those disclosed in U.S. Pat. No. 4,666,948, “Preparation of Resilient Melamine Foams,” issued May. 19, 1987 to Woerner et al.; U.S. Pat. No. 5,234,969, “Cured Phenolic Foams,” issued Aug. 10, 1993 to Clark et al.; U.S. Pat. No. 6,133,332, “Process for Producing Phenolic Resin Foams,” issued Oct. 17, 2000 to T. Shibanuma; and WO 91/14731, “Stable Aminoplast Cellular Foams and Process for Manufacturing Them,” published Oct. 3, 1991 by Mäder et al., all of which are herein incorporated by reference. The latter, WO 91/14731, discloses cellular foams obtained by using an unsaturated, halogenated polyalcohol in a resin precondensate constituent and a dodecylbenzolsulphonic acid partially esterified preferably with a fatty alcohol and a long-chain polyhydric alcohol such as a polyethylene glycol, in a foaming agent hardener constituent.
Principles for manufacturing melamine-based foam are well known. Melamine-based foams are currently manufactured by BASF (Ludwigshafen, Germany) under the BASOTECT® brand name. For example, BASOTECT® 2011, with a density of about 0.01 g/cm3, may be used. The cleaning block 92 of melamine-based foam may be as that marketed by Procter & Gamble (Cincinnati, Ohio) under the MR. CLEAN® brand name, and under the CLEENPRO™ name by LEC, Inc. of Tokyo, Japan (several product executions are shown at http://www.users.bigpond.com/jmc.au/CLEENPRO/CLEENPRO-E.htm and http://www.users.bigpond.com/jmc.au/CLEENPRO/CLEENPRO%20Family-E.htm, both printed on Nov. 13, 2003). Melamine-based foam is also marketed for acoustic and thermal insulation by many companies such as American Micro Industries (Chambersburg, Pa).
Other foams that can be used are as described in German publication DE-AS 12 97 331. Those foams are formed from phenolic components, urea-based components, or melamine-based components, or are in an aqueous solution with a blowing agent and a hardening catalyst.
The cleaning wipe 18 need not include a melamine-based foam 90 or other type of cleaning foam in accordance with other exemplary embodiments of the present invention. For instance, the cleaning wipe 18 may be made out of a tissue, spunbond webs, meltblown webs, textiles, or the like or any combination thereof. Additionally, the cleaning wipe 18 may be a coform material that may be formed from cellulose and meltblown fibers possibly having an optional layer of meltblown, spunbond or film laminated on either side of the composite.
The cleaning product 10 may be provided with a battery powered heating element in order to heat the cleaning wipes 18 in order to improve their ability to clean a soiled surface. The cleaning wipe 18 may be made of a disbursable component so that the cleaning wipe 18 disintegrates when contacted or saturated by water.
It should be understood that the present invention includes various modifications that can be made to the embodiments of the cleaning product 10 as described herein as come within the scope of the appended claims and their equivalents.
