Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mop head refill that clings and/or sticks to an underside of a conventional mop head holder.

2. Discussion of Related Art

The use of a resilient, compressible fibrous nonwoven material for various cleaning purposes is conventional. Nonwovens are not based on yarns, but rather are based on webs of individual fibers (or filaments) that are bonded together, such as by adding an adhesive, thermally fusing the fibers (or filaments) to each other or to other meltable fibers or powders, fusing fibers (or filaments) by first dissolving and then resolidifying their surfaces, creating physical tangles or tuft among fibers (or filaments), or stitching the fibers (or filaments) in place.

Indeed, nonwovens are a manufactured sheet, web or bat of directionally or randomly oriented fibers, bonded by friction, and/or cohesion and/or adhesion, excluding paper or products which are woven, knitted, tufted stitch bonded incorporating binding yarns or filaments, or felted by wet milling, whether or not additionally needled. The fibers may be of natural or man-made origin. They may be staple or continuous or be formed in situ. According to The Nonwoven Fabrics Handbook, Association for the Nonwoven Fabrics Industry, Cary, N.C., nonwovens are mainly dominated commercially by three fibers, namely polyolefin, polyester and rayon and have been used, among many other applications, in buff pads, dust cloths and mops.

U.S. Pat. No. 3,537,121, whose contents are incorporated by reference, divulges a soft resilient compressible polishing pad that is essentially a lofty fibrous nonwoven structure bonded by a soft, tough resin containing a finely divided soft mineral fiber. This compressible polishing pad is for cleaning (with compounds), buffing, or restoring surfaces.

U.S. Patent Publication No. US 2003/0140441 A1 describes a manner of attaching a scrubbing pad to a mop holder and to a scrub applicator. One side of an upper adhesive strip is adhered permanently to the underside of a bar member, while one side of a lower adhesive strip is permanently adhered to the top surface of the scrubbing pad. The opposing faces of the two adhesive strips are covered with a pressure sensitive fastening layer such as VELCRO, so that application of pressure to the top surface of the bar member causes the two adhesive strips to engage each other and hold the pad firmly to the applicator bar member. If it becomes necessary to remove and replace the pad, the strips can be disengaged by using a tensile tearing action. This allows the scrubbing pad to be removed.

U.S. Pat. No. 6,810,554 mentions a cleaning tool with removable cleaning sheets. Such is suitable for a refill of a mop head. The mop head is equipped with gripping means to retain the cleaning sheets on the mop head.

U.S. Patent Application Publication No. 2010/0044909 reveals a method of making a tackified nonwoven sheet that includes forming a densified, tackified web by providing a rebulkable nonwoven fiber web and applying an adhesive to the nonwoven web. The densified, tackified web is rebulked to an open, lofty form by exposing the densified, tackified web to a temperature of at least 225.degree. F. Finally, a sheet is formed from the rebulked, tackified web. An adhesive is applied directly to the rebulkable nonwoven web.

There are many different kinds of mops available whose mop head holder is configured to retain a replaceable mop head. Mop head refills are typically provided to allow the user to replace the mop head should it become too worn, damaged or dirty. Typically, the manner in which the refill attaches to the underside of the mop head holder differs from mop to mop so that the user may feel compelled to purchase refills from the original maker of the mop to be assured that the refill is retained by the mop head holder in a secure manner and that the durability of the mop head will be the same as before.

It would be desirable to provide a mop head refill product that clings and/or sticks to the underside of any conventional mop head holder and whose performance should outlast that of a conventional cleaning sheet on a mop head.

SUMMARY OF THE INVENTION

One aspect of the invention resides in a refill with a fibrous composition that allows the refill to be retained to the underside of any mop head holder securely that has a surface texture suited to secure with minute hook fasteners. Alternatively, in those cases where the underside of the mop head lacks such a surface texture, such as when flat, a fastening tape is provided with the refill to effect such a securement. The fastening tape has a tacky or sticky surface on one side and a pattern of minute hooks on the other. The minute hooks cling to the refill while the tacky or sticky surface adheres to the underside of the mop head holder. A plastic backing may be placed over the tacky or sticky surface to be peeled off prior to actual use of the fastening tape on the underside of the mop head holder.

The refill is preferably a fibrous nonwoven structure, compressible and resilient and preferably polyurethane, polyester, polyolefin, rayon, any combination thereof, or the mop head refill may be a lofty fibrous nonwoven structure bonded by a soft, tough resin containing a finely divided soft mineral fiber. Preferably, the refill and the fastening tape are packaged together and may include in the same packaging further refills and/or further adhesive tapes. To simplify securing the refill to the underside of a conventional mop head holder for the user, the fastening tape may be secured to a face of the refill within the package and thereby to appropriately centered across the face of the refill.

DETAILED DESCRIPTION OF THE INVENTION

Turning to FIG. 1, two mop head refills 10 in accordance with the invention are shown lying with one of their faces on a floor. The material of the mop head refill 10 is preferably a fibrous nonwoven structure, compressible and resilient and preferably polyurethane, polyester, polyolefin, olefin. nylon, rayon, or any combination thereof, or the mop head refill may be a lofty fibrous nonwoven structure bonded by a soft, tough resin containing a finely divided soft mineral fiber as set forth in U.S. Pat. No. 3,537,121, whose description of the composition of its pad is incorporated herein by reference. Alternatively, the fibrous nonwoven structure may be a densified, tackified web made in accordance with the manufacturing disclosure in US patent application publication no. US 2010/0044909 A1, whose contents are incorporated herein by reference. Preferably, the fibrous nonwoven structure of the refill 10 is hydrophobic to thereby lack affinity for water and thus tend to repel and not absorb water. Nevertheless, to the extent that the surface texture of the refill 10 is uneven and unsmooth and the refill is porous, the refill 10 can be wetted.

One of the two mop head refills 10 of FIG. 1 has a fastening tape 12 consisting of a strip of nylon with two faces. One face has a surface of minute hooks 14 that fasten to a corresponding strip with a surface of uncut pile (uncut loops of yarn forming the surface of certain fabrics, such as velvet, plush, and carpeting). The other face has a surface that is tacky or sticky (such as that of an adhesive). Prior to applying the tacky or sticky surface to the underside of a mop head holder, a plastic backing 16 needs to be peeled off the tacky or sticky surface. Such a fastening tape 12 is available under the tradename “VELCRO”.

The fastening tape 12 may be the same as that described for the adhesive tape in US patent application publication no. US 2003/014041 A1, whose contents are incorporated by reference, but with the addition of a peel away plastic strip on the tacky or sticky side of the adhesive tape. Adhesives that provide a tacky or sticky surface are conventional. For instance, the adhesives mentioned in US patent application publication no. US 2010/0044909 A1, whose contents are incorporated herein by reference, are suitable, namely, the adhesive can assume a variety of forms, and in some embodiments, is or includes a water-based pressure sensitive adhesive.

Pressure sensitive adhesives are normally tacky at room temperature and can be adhered to a variety of surfaces by application of light finger pressure. An adhesive bond is developed by a second surface (or individual particles of a second material such as, for example, dust, dirt, crumbs, or other debris) pressed against the pressure sensitive adhesive coated material. Alternatively, suitable adhesives for use with the present disclosure include any that are capable of being tacky at room temperature, including both adhesives that are initially tacky and those that are initially non-tacky but which can be activated to become tacky. Suitable adhesives include any pressure sensitive adhesives including materials based on acrylates, silicones, poly-alpha-olefins, polyisobutylenes, rubber block copolymers (such as styrene/isoprene/styrene and styrene/butadiene/styrene block copolymers, styrene/butadiene/rubbers, synthetic isoprenes, natural rubber, and blends thereof).

While the pressure sensitive adhesives useful with the present disclosure are preferably water based, in other embodiments, the pressure sensitive adhesives may be coated from solvents, radiation polymerized, or hot melt processed. These pressure sensitive adhesives may or may not be cross-linked. Cross-linking can be done by well-known methods, including chemical, ionic, physical, or radiation-induced processes. Other useful adhesive compositions may include, for example, polyvinyl ethers, ethylene containing copolymers such as ethylene vinyl acetate, ethylacrylate, and ethylmethacrylate, polyurethanes, polyamides, polyepoxides, polyvinylpyrrolidones, and copolymers thereof, polyvinyl alcohols, and copolymers thereof, polyesters, and combinations thereof.

A general description of useful pressure sensitive adhesive compositions can be found in the Encyclopedia of Polymer Science and Engineering, Volume 13, Wiley-Interscience Publishers (New York 1988). As discussed in the Handbook of Pressure Sensitive Adhesive Technology, Second Edition (D. Satas, Editor Van Nostrin Reinhold, New York, 1989), these adhesives may be based on polymers like natural rubber, acrylates, styrene-budadienes, and vinyl ethers. Further, the elastomeric block copolymers of the adhesive composition may be formulated with tackifying resins (tackifiers) to improve adhesion and introduce tack into the pressure sensitive adhesive.

Suitable tackifier resins are described in the Handbook of Pressure Sensitive Adhesive Technology referenced above, and can include rosin esters, terpenes, phenols, and aliphatic, aromatic, or mixtures of aliphatic and aromatic synthetic hydrocarbon monomer resins. The tackifier components useful in block copolymer adhesive compositions can be solid, liquid, or a blend thereof. Suitable solid tackifiers include rosin, rosin derivatives, hydrocarbon resins, polyterpenes, coumarone indenes and combinations thereof. Suitable liquid tackifiers include liquid hydrocarbon resins, hydrogenated liquid polystyrene resins, liquid polyterpenes, liquid rosin esters, and combinations thereof. Many tackifiers are commercially available, and optimum selection thereof can be accomplished by one of ordinary skill in the adhesive compounding art.

The adhesive composition can also include additives such as, for example, plasticizers, diluents, fillers, antioxidants, stabilizers, pigments, cross-linking agents, and the like.

The formation of nonwoven fibers is conventional. All nonwoven fabrics are based on a fibrous web, whose characteristics determine the physical properties of the final product. These characteristics depend largely on the web geometry, which is determined by the mode of web formation. Web geometry includes the predominant fiber direction, whether oriented or random, fiber shape (straight, hooked or curled), the extent of inter-fiber engagement or entanglement, crimp and z-direction compaction. Web characteristics are also influenced by the fiber diameter, fiber length, web weight, chemical and mechanical properties of the polymer.

The choice of methods for forming webs is determined by fiber length. Initially, the methods for the forming of webs from staple-length fibers are based on the textile carding process, whereas web formation methods from short fibers are based on papermaking technologies. Also, webs may be formed from long, virtually endless filament directly from bulk polymers; both web and fibers are produced simultaneously.

FIG. 2 shows a group of the refills 10 standing upright on the floor 18 along their respective long sides although they are unbent. This means the thickness of these long sides (i.e., between the top and bottom faces) must be sufficient to provide for such stability. Such a characteristic is useful for compact storage where storing the refills 10 upright along their respective long sides on a shelf is needed due to storage space constraints. Such upright standing refills 10 will not topple over by themselves once placed in such an orientation.

The mop head refill 10 preferably has an areal face dimension suited to substantially cover the entire area of the underside face of a conventional mop head holder, such as an area of ten inches by five inches, as exemplified by the underside face 20 of the conventional regular mop head holder of FIG. 5. Indeed, the topside of the mop head refill 10 essentially sticks to the underside of any conventional standard size mop head holder of regular size mops. For oversized mop head holders, two refills may be stuck to the underside of such oversized mop head holders. The geometry of the mop refill head 10 is therefore preferably substantially a rectangular solid.

If the underside of the mop head holder has hook fasteners built up at the bottom, just stick the refill 10 directly to the underside as in FIG. 3. The refill 10 will hold itself by clinging to the built up hook fasteners because the fibers at the outer surface of the refill 10 entangle or become caught in the hook fasteners.

FIG. 3 shows the placement of the refill 10 against the underside of the mop head holder 20, which in turn is attached to a mop pole handle 22. The mop head refill 10 shown in FIG. 3 does not have the fastening tape 12. Instead, the mop head refill 10 is placed against, as best seen in FIG. 5, the underside of the conventional mop head holder that has its own hook fastening strips 24. The hook fastening strips 24 cling onto the ends and loops of the fibrous nonwoven structure of the refill 10 to retain the refill 10 against falling off, as best appreciated from FIG. 4. FIG. 4 shows that the refill 10 clings to the underside of the mop head holder 20 and does not readily fall off by itself, even though the refill 10 is elevated off the floor and faces downward.

If, however, the mop head holder is flat at the bottom instead, then stick the fastening tape 12 to the refill 10, peel the plastic backing 16 and stick the tacky side to the underside of the mop head holder 12. When finished, just peel off the refill from the mop, but do not detach the hook and loop strip from the mop head holder.

After sticking to the underside of any conventional mop head holder, the mop head refill 10 may perform any of the following actions when slid across a floor to be cleaned:

• • grabs dust, hair and lint, whether wet or dry
  • removes stains, grease, grime, chemical build-up
  • gets into grooves and ridged surfaces without scratching the floor
  • safe for use with water or suitable cleaning solutions on any type of floor surface, including vinyl, ceramic, laminated, tile or wood floors, because its gentle and smooth scrubbing power does not damage or scratch floors
  • remains intact without flaking or falling apart over extended use, unlike sponges
  • avoids retaining chemicals, odors or stained once it is rinsed, because of its porous consistency
  • reusable after rinsing with warm water (but not machine washable)

The mop head refill 10 is suited for all floor cleaning needs with just one refill for a regular size mop head holder or two for oversize mop head holders—just wet the mop head with water and/or suitable cleaning solution, squeeze out excess water or solution, and stick the mop head to the underside of a mop head holder. Indeed, the mop head refill 10 is, in effect, universal in its ability to stick to the underside of all types of mop head holders.

If desired, the mop head refill 10 may be pulled off the underside of the mop head holder, leaving behind the fastening tape 12 still adhered to the underside of the mop head holder. There is no need to remove the fastening tape 12 from the underside of the mop head holder. Indeed, the same mop head refill 10 may be flipped over and pressed against that same fastening tape 12 or a fresh refill may be pressed on instead so as to carry out the aforementioned actions as well when slid across a floor.

FIGS. 6 and 7 illustrate the conventional use of a hook fastening strip 30 that is permanently attached to the forward side of a conventional mop head 20. A detachable scrubber 32 is made of material that can cling onto the hook fastening strip 30 and be used thereafter for scrubbing surfaces with the mop.

Although not shown in the drawings, the mop head refill 10 may be packaged individually together with a fastening tape 12 in the same package. The fastening tape 12 may already be secured to the mop head refill 10 as shown in FIG. 2. Thus, the user has the option of removing the plastic backing 16 to apply the tacky or sticky side of the fastening tape 12 to a portion of the underside of a conventional mop head holder and, as applicable, press the mop head refill 10 against the rest of the underside of the convention mop head holder as well to cling them to each other, provided the underside of the mop head holder is so equipped with a surface texture that clings (such as that exemplified by FIG. 5). The user also has the option of pulling off the fastening tape 12 entirely from the mop head refill 10 to press the mop head refill 10 against the underside of the mop head holder to cling to the same in the situation in which the underside of the mop head holder is so equipped with a surface texture that can cling to the mop head refill 10.

Further, multiple mop head refills 10 may be packaged together in the same packaging by being oriented either side-to-side (see FIG. 1, but abutting each other at their sides) or face-to-face (see FIG. 2, but abutting each other at their faces) or end-to-end (not shown, but abutting each other). The same packaging contains adhesive tapes 12, preferably each secured to a face of applicable ones of the mop head refills 10.

Some advantages in packaging the fastening tape secured to the face of a mop head refill include avoiding the need to provide further protection to the hook side of the adhesive tape to prevent damage, centering the fastening tape on the face of the mop head refill so that it would align properly against the underside of a mop head holder analogous to that of FIG. 5 without the need for the user to figure out where exactly the adhesive tape should be positioned on the face of the refill, and speeds up the time it takes for the user to secure the refill to the underside of the mop head holder since the user does not need to be concerned about figuring out where the adhesive tape should be arranged exactly on the face of the refill to be appropriately centered.

Since the same adhesive tape may be reused for different refills for the same mop head holder, the single package may contain multiple refills with no adhesive tape secured to them and one or two refills with adhesive tape secured to them. For instance, the five refills of FIG. 2 may be packaged together with there being only two adhesive tapes being present in that single package, i.e., clinging to just two of the refills.

In all the embodiments, the mop head refill 10 need not have any other components besides the fibrous, nonwoven structure. That is, there is no need for the addition of sponge material or any wipe covering fabric to encircle the fibrous, nonwoven structure.

For all the embodiments, the mop head refill 10 and the fastening tape 12 are packaged together in a common package. The package may be two halves each of a transparent plastic that is sonic or thermal welded together at its seams to contain the mop head refill 10 and the fastening tape 12. One end or both ends of the package may have an associated flap that opens to allow insertion or removal of the mop head refill 10 and the fastening tape 12 or that closes to help protect contents of the package from the environment prior to purchase by the end user. Multiple refills 10 may be packaged together in the same package—only one or two fastening tapes 12 need to be provided since they are intended to remain on the underside of the mop head holder as the mop head refill is eventually replaced by a replacement mop head refill later on. Thus, depending upon the shape and size of the package, the refills may be positioned within the package to abut each other at their faces, along their sides or along their ends.

Where fastening tapes 12 cling to associated faces of the refills 10 inside the common package, the refills may be positioned face to face with their fastening tapes abutting each other along their plastic backings or with at least one of the fastening tapes sandwiched between the face of one of the refills (that it clings to) and the face of another refill. If the fastening tapes are positioned on respective faces of different refills in such a manner that they are offset from each other if the refills are brought together face to face, the fastening tapes could be side by side relative to each other to conserve packaging space. Such contrasts with positioning them centrally across the faces such that their plastic backings touch each other (face to face) if the refills are brought together with their fastening tapes positioned between them.

While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the scope of the present invention.
