  • FIG. 1 is a side view of a first embodiment of a cleaning device 100.
  • FIG. 2 is a side view of the cleaning device 100 shown while being used to wipe a surface 170.
  • the cleaning device 100 is a composite comprising at least a first substrate 140 and a second substrate 150.
  • the cleaning device 100 includes a working surface 110 that is textured having a plurality of raised regions 120 and a plurality of recessed regions 130.
  • the first substrate 140 and second substrate 150 are connected to one another in such a way to form a composite.
  • the first substrate 140 forms a layer while the second substrate 150 forms another layer, that is directly adjacent the layer of the first substrate.
  • the first and second substrates are connected through adhesive, lamination, or heat fusion.
  • the first substrate 140 forms the raised regions 120, while the second substrate 150 forms the recessed regions 130.
  • the first substrate 140 is a solid, compressible material having a working, compressible thickness.
  • the second substrate 150 is a solid, compressible material having a working, compressible thickness. Therefore, very thin films or thin woven, nonwoven, or knitted wipes are not suitable for the first or second substrate.
  • the cleaning device 100 has a thickness of at least 1 cm.
  • Suitable materials that are solid, compressible materials useful for the first and second substrates include all types of foams and compressible scouring materials, such as lofty fiber webs.
  • the first substrate 140 and second substrate 150 may both be foams, both be scouring materials, or one may be a foam and one may be a scouring material. When both are foams or both are scouring materials, the first and second substrates may comprise foams different from one another or scouring materials different from one another.
  • suitable foams include synthetic foams or cellulose sponge.
  • Synthetic foams are particularly well suited because the foam is a flexible, compliant material that can contour over the surface being cleaned and can absorb liquid.
  • the synthetic foam could be an open cell foam or a closed cell foam.
  • Synthetic foams, particularly open cell synthetic foams are less hydrophilic and have a low ability to retain liquid within the structure as compared to cellulose sponge. Therefore, although fluid is easily absorbed in the material, the fluid is also easily flushed from the less hydrophilic foam. It is believed that the fast flushing through the pores of the less hydrophilic foam causes soap to become very sudsy as it passes in and out of the foam.
  • a synthetic foam will dry faster than a more hydrophilic material such as cellulose sponge.
  • Synthetic sponge may be made from rubber, polyether, polyester, melamine, neoprene, SBR, butadiene, nitrile, EPDM, ECH, polystyrene, polyethylene, polypropylene, polyurethane, EVA, EMA, metallocene resin, PVC, melamine or blends of any of the above, and the like. It is understood that different materials for a synthetic sponge or even different properties within a synthetic sponge can result in synthetic sponges having different compressibility. Therefore, for example, a PVC sponge with large pores may be used as the first substrate, while a PVC sponge with small pores may be used as the second substrate because each of these PVC sponges has different properties such as compressibility.
  • Cellulose-based sponges can be used as one of the first or second substrates.
  • Cellulose-based sponges can include those which are derived from plant products for example.
  • Cellulose sponge provides a particularly unique wiping surface because cellulose sponge is flexible and conformable and is a hydrophilic sponge that is capable of absorbing and retaining fluids. Therefore, when a damp cellulose sponge is wiped over a surface, large amounts of liquid are not deposited onto the surface being wiped. Further, spills of liquids can be absorbed and retained in the cellulose sponge until the cellulose sponge is squeezed.
  • Compressible scouring materials may be used for the substrates. Examples of compressible scouring materials include compressible, interconnected fibers.
  • Fibers can be interconnected as knitted, woven, or nonwoven webs of fibers.
  • the fibers may be natural, synthetic or a combination of natural and synthetic fibers.
  • a compressible scouring material is relatively rigid.
  • stiff fibers may be used and/or the fibers may be coated with a binder. It is understood that certain foams having sufficient rigidity may also function as a compressible scouring material. For example, foamed melamine is well suited for scouring.
  • Second substrate 150 may comprise an incompressible material in combination with first substrate 140 comprising a compressible material.
  • incompressible materials are those which, when subjected to manual compression by a typical user, do not change significantly in volume at least to the eye of the user.
  • Exemplary incompressible materials include rigid foams and various types of rigid abrasive webs.
  • the side view in FIG. 1 shows a first row 111 of raised regions 120 and behind the first row is a second row 112 of raised regions. This surface topography is commonly referred to a "convoluted.”
  • the raised regions 120 are discrete and are spaced from one another, and the recessed regions 120 are discrete and are spaced from one another.
  • a convoluted surface topography has a "mirror image" of the raised regions and recessed regions.
  • the raised regions 120 are aligned generally linearly; however, from row to row, as can be seen in FIG. 1, the raised regions 120 are off set from one another. Macroscopically, this arrangement of raised regions 120 and recessed regions 130 provides both the first substrate and second substrate across the entire working surface. Therefore, both the first substrate and second substrate are readily accessible to the user.
  • the uppermost portion 124 of the raised regions 120 are convexly curved, while the lowermost portion 134 of the recessed regions 130 are concavely curved. Therefore, the side walls between the uppermost portion 124 and the lowermost portion 134 are sloping and have an inflection point. In this embodiment, the inflection point is approximately midway between the uppermost portion 124 of the raised region 120 and the lowermost portion 134 of the recessed region 130. With the sloping side walls, the perimeter of the raised region 120 gets larger closer to the recessed region 130. Therefore, upon compression of the first substrate 140, the underlying second substrate 150, having a larger diameter, becomes more readily available to the working surface 110.
  • the side walls may be straight lines and not curved and that the surfaces of the raised region and/or the recessed region may also be flat and not curved.
  • the first substrate 140 forming the raised region 120 is a foam and the second substrate 150 forming the recessed region 130 is a compressible scouring material that is shown as a nonwoven web of fibers.
  • the foam is more compressible than the nonwoven web.
  • This combination of materials for the raised regions and recessed regions provides a working surface that can wipe with the foam when light pressure is applied and can scour with the nonwoven web when heavy pressure is applied to compress the foam. With light pressure, the side walls can provide additional surface area for wiping or slight scouring.
  • FIG. 2 (where the second row 112 has been removed for clarity in viewing) clearly shows that under heavy pressure the foam raised regions 120 are compressed to bring the recessed regions 130 into contact with the surface 170 being cleaned. Therefore, a single working surface 110 can provide both wiping and scouring through the selective engagement of the raised regions 120 and the recessed regions 130.
  • FIG. 3 is a perspective view of a second embodiment of a cleaning device 200.
  • FIG. 4 is a side view of the cleaning device 200 shown in FIG. 3 while being used to wipe a surface 270.
  • the cleaning device 200 is a composite comprising at least a first substrate 240 and a second substrate 250. As in FIG. 1, the first substrate 240 is a layer and the second substrate 250 is an adjacent layer.
  • the cleaning device 200 includes a working surface 210 that is textured having a plurality of raised regions 220 and a plurality of recessed regions 230.
  • the cleaning device 200 is shown in FIG. 3 as a square-shaped device. It is understood that the other embodiments disclosed herein could have a similar to that shown in FIG. 3. It is also understood that any other shapes could be used.
  • the first substrate 240 forms the raised regions 220, while the second substrate
  • the raised regions 220 are discrete and are spaced from one another by recessed regions 230.
  • the raised regions 220 extend from one end of the cleaning device 200 to another end.
  • the raised regions 220 are linear and are parallel to one another. Therefore, the recessed regions 230 are linear and are parallel to one another but separated from one another by the raised regions 220.
  • the uppermost portion 224 of the raised regions 220 are convexly curved, while the lowermost portion 232 of the recessed regions 230 are concavely curved. Therefore, the side walls are sloping and have an inflection point. In this embodiment, the inflection point is approximately midway between the uppermost portion 224 of the raised region
  • the perimeter of the raised region 220 gets larger closer to the recessed region 230. Therefore, upon compression of the first substrate 240, it is believed that slightly less force is required to compress the first substrate because less material will stack against itself as compared to a more cube shaped raised region with linear side walls. Also, the side walls are more accessible for wiping or scouring to provide cleaning surface area for material projecting upward from the surface 270 being cleaned.
  • the first substrate 240 forming the raised region 220 is a compressible scouring material that is shown as a nonwoven web
  • the second substrate 250 forming the recessed region 230 is a foam.
  • the foam is more compressible than the nonwoven web.
  • the recessed region 230 being a compressible foam provides for overall flexibility of the cleaning device 200. With the more rigid second substrate 250 disconnected in areas, the cleaning device can easily flex, bend, and contour over a surface 270 to be cleaned. Also, the recessed region 230 being a compressible foam provides a conformable and comfortable surface for holding. In addition, with heavy pressure applied, the foam can make contact or near contact with the surface 270 being cleaned to wipe or absorb liquid on the surface. Therefore, a single working surface 210 can provide both wiping and scouring through the selective engagement of the raised regions 220 and recessed regions 230. It is also contemplated that first substrate 240 may comprise an incompressible material in combination with second substrate 250 comprising a compressible material.
  • FIG. 5 is a side view of a third embodiment of a cleaning device 300.
  • the cleaning device 300 is a composite comprising at least a first substrate 340 and a second substrate 350.
  • the second substrate 350 is embedded with and distributed throughout the first substrate 340.
  • the cleaning device 300 includes a first working surface 310 that is textured having a plurality of raised regions 320 and a plurality of recessed regions 330 and a second working surface 315 that is textured having a plurality of raised regions 320 and a plurality of recessed regions 330. Therefore, it is understood that a single cleaning device 300 can have a single textured working surface (FIGS. 1-4) or more than one textured working surface (FIG. 5). Also, although the second working surface 315 is shown to have similar raised regions 320 and recessed regions 330. However, in this embodiment, the raised regions 320 of the second working surface 315 are offset from the raised regions 320 of the first working surface 310.
  • a third substrate 360 in included at the raised region 320 on the second working surface 315. It is understood that the substrates used for the different working surface may be the same or different from one another and the arrangement and configuration of the different working surface may be the same or different from one another.
  • a cleaning device may have a first working surface as shown by working surface 310 in FIG. 5 and a second working surface as shown by working surface 210 in FIG. 3.
  • the second substrate 350 is embedded and distributed throughout the first substrate 340. Therefore, at the first working surface 310 a portion of the first substrate 340 forms the raised regions 320 and the recessed region 330, and a portion of the second substrate 350 forms the raised regions 320 and the recessed regions 330. At the second working surface 315 the third substrate 360 forms the raised regions 320 and a portion of the first substrate 340 and a portion of the second substrate 350 forms the recessed region 330.
  • the raised regions 320 are discrete and are spaced from one another by recessed regions 330 and the recessed regions 330 are discrete and are spaced from one another by raised regions 320.
  • Raised regions 320 in this embodiment include side walls that are generally sloping.
  • the uppermost portion 324 of the raised region 320 is a convex curved surface.
  • the lowermost portion 332 of the recessed region 330 is concavely curved.
  • the first substrate 340 is a foam and the second substrate 350 is a fiber cluster embedded within the foam.
  • the fiber cluster is less compressible than the foam.
  • Such a material is shown and described in US Patent Application 12/421,753 titled “Cleaning Sponge” filed on April 10, 2009. Therefore, overall the cleaning device 300 is compressible wherein when force is applied the foam is compressed and the fiber clusters provide scouring over a surface being cleaned.
  • the third substrate 360 is a compressible scouring material shown as a nonwoven web of fibers. This combination of materials, wherein the first substrate 340 and second substrate 350 comprise both the raised regions 320 and recessed regions 330 provides a working surface that is highly effective for wiping because the foam is throughout the entire working surface.
  • the working surface is effective for scouring.
  • the user can control the extent to which the fiber clusters of the second substrate 350 are pressed against the surface being cleaned.
  • the side walls of the raised region which includes the first substrate 340 and second substrate 350, can be effective for scouring material raised from a surface to be cleaned and also provide additional surface area to absorb liquid extending from a surface to be cleaned.
  • a single working surface 310 or 315 can provide both wiping and scouring through the selective engagement of the raised regions 320 and recessed regions 330.
  • the third substrate 360 forming the raised region 320 at the second working surface 315 that is aligned with the recessed region 330 of the first working surface 310, aids in pressing the recessed region 330 at the first working surface into contact with a surface to be cleaned because more material is forced under pressure into the backside of the recessed region 330 at the first working surface 310. This is true for the opposite: the second working surface 315.
  • first and third substrates, 340 and 360 are either compressible or incompressible, as long as one of the two substrates is compressible.
  • first substrate 340 may be a compressible material
  • third substrate 360 an incompressible material.
  • first substrate 340 may be an incompressible material
  • third substrate 360 a compressible material.
  • FIG. 6 is a side view of a fourth embodiment of a cleaning device 400.
  • the cleaning device 400 is a composite comprising a first substrate 440, a second substrate 450, and a third substrate 460.

  • the third substrate 460 is positioned between the first substrate
  • the raised regions 420 are discrete and are spaced from one another by the recessed regions 430.
  • the recessed regions 430 are discrete and are spaced from one another by the raised regions 420.
  • the arrangement of the "convoluted" raised regions and recessed regions is similar to that shown in FIGS. 1-2.
  • Raised regions 420 in this embodiment include side walls that are generally sloping.

  • the lowermost portion 432 of the recessed region 430 is concavely curved.
  • the curvature is nearly continuous such and the side walls generally do not form a straight line. It is believed that this sloping of the side walls provides more surface area available for contact with a surface being cleaned when the cleaning device 400 is passed over the surface and pressure is applied. With very slight pressure applied to the cleaning device 400, the underlying third substrate 460, being larger in diameter than the upper most first substrate 440 can come into contact with a surface being cleaned.
  • the first substrate 440 forming the raised region 420 is a foam

  • any many different combinations of materials may be used for the different substrates so long as one material is more compressible than the second material.
  • many different substrates may be included to form the composite of the cleaning device. As was shown with FIGS. 1, 3, and 6, multilayer arrangement of the substrates may be used to provide the composite and resulting arrangement of the substrates at specified locations on the raised region and recessed region. It is understood that the entire raised portion may include the first substrate while only the lowermost portion of the recessed region may include the second substrate. It is understood that the uppermost portion may include the first substrate, while the lowermost portion and nearly the entire remaining raised region may include the second substrate.
  • One or more working surfaces may be included having a variety of shapes, configurations, and arrangements of the raised region and recessed region. As was already discussed, the working surface is used over a surface to be cleaned to wipe or scour the surface. Various amounts of pressure are applied to the cleaning device to selectively engage portions of the raised region or the recessed region.
  • the composite is formed. This may be a layered structure with the layers secured together or may be a structure with embedded material (FIG. 5). Once the composite is formed, the material is then “convoluted.” By convo luting, the composite is passed through a nip between a pair of rollers having interdigitated projections to compress different portions of the layer of composite toward its opposite side surfaces and then slitting the compressed layer of composite with a blade to produce two halves of the layer of composite each with raised regions and recessed regions. Other types of cutting devices can be used to cut the substrates.

Abstract

Selon l'invention, un composite à matériau multiple, les matériaux étant positionnés en des régions surélevées (120/220/320/420) et des régions en cavité (130/230/330/430) sur la surface de travail (110/210/310,315/410), permet à un dispositif de nettoyage (100/200/300/400) aussi bien de décaper que d'essuyer une surface unique. Grâce à la disposition en cavité d'un ou de plusieurs matériaux vis-à-vis de la surface de travail, l'utilisateur peut contrôler, avec une pression, l'ampleur selon laquelle la région en cavité vient en contact avec une surface devant être nettoyée (170/270). Le composite peut avoir au moins un premier substrat (140/240/340/440) qui est un matériau compressible, et un second substrat (150/250/350/450), qui est un matériau compressible.
