Cleaning Implement

[0033] Referring to FIGS. 1-8, one non-limiting embodiment of the cleaning implement of the present invention is shown. Cleaning implement 10 is comprised of handle 20 connected to cleaning head 30. Handle 20 may be comprised of a single solid component. Alternatively, handle 20 may be comprised of one or more components which are joined together. Handle 20 includes an upper area 21 and a lower area 22. Cleaning head 30 is comprised of a top and a bottom (not shown). The lower area 22 of handle 20 is connected to the top of cleaning head 30. Handle 20 may be stationary and/or may be capable of pivoting and/or rotating or a combination thereof.

[0034] The upper area 21 of handle 20 may include an indentation 23 on one or both ends of the upper area 21. While not wishing to be limited by theory, it is believed that indentations 23 facilitate gripping of handle 20 and provide a comfortable fit for the user's fingers. In one non-limiting example, indentation 23 may be about 0.25 inches (6.35 mm) in depth and may be located about 3.5 inches (8.9 cm) from the center of handle 20 as measured in the longitudinal direction of the handle.

[0035] Upper area 21 of handle 20 may be comprised of a single unit. Alternatively, upper area 21 of handle 20 may be comprised of more than one component such as shown in FIG. 7. Referring to FIG. 7, upper area 21 is comprised of top component 210 and bottom component 211 which are joined together. Bottom component 211 is joined to lower area 22 of handle 20.

[0036] In one non-limiting example, top component 210 of upper area 21 of handle 20 may be comprised of a flexible polymer such as thermoplastic elastomer ("TPE"). The top component 210 may be about 0.093 inches (2.36 mm) or less in thickness. The flexible polymer may be opaque, translucent, transparent, or a combination thereof. The bottom component 211 of upper area 21 of handle 20 may be made out of a rigid polymer non-limiting examples of which include polypropylene and acrylonitrile-butadiene-styrene ("ABS") or combinations thereof. The bottom component 211 may be about 0.25 inches (6.35 mm) or less in thickness. The rigid polymer may be opaque, translucent, transparent, or a combination thereof. Top component 210 and bottom component 211 may be joined together by a process that bonds the flexible polymer to the rigid polymer, non-limiting examples of which include injection molding or adhesive bonding. The lower area 22 of handle 20 may be comprised of a rigid polymer such as polypropylene or ABS. The lower area 22 may be about 0.25 inches (6.35 mm) or less in thickness. The rigid polymer may be opaque, translucent, transparent or a combination thereof. Upper area 21 and/or lower area 22 of handle 20 may include support structure 25. When included, support structure 25 if desired, may be arranged in an aesthetically pleasing visual manner. For example, in one non-limiting embodiment, some portion of handle 20 could be translucent or transparent such that some portion of the support structure 25 is visible. Additionally or alternatively, support structure 25 if desired could be located on the exterior of handle 20. Additionally or alternatively, if desired an aesthetically pleasing visual pattern could be included on handle 20.

[0037] The upper area 21 of handle 20 may be joined to lower area 22 of handle 20 in any number of different ways, non-limiting examples of which include utilizing one or more snaps and/or one or more screws to join the parts, and/or bonding the parts together such as by adhesive bonding or ultrasonic welding. Referring to FIG. 7, in one non-limiting example of the use of a snap, bottom component 211 of upper area 21 of handle 20 includes protrusion 212 which coincides with boss 220 of lower area 22 of handle 20 so as to join upper area 21 with lower area 22.

[0038] Referring to FIGS. 1-8, cleaning head 30 includes a top and a bottom. Cleaning head 30 may also include attachment structure 43 for attaching a cleaning sheet. Though not shown, attachment structure 43 could alternatively (or additionally) be included with handle 20. The top of cleaning head 30 is comprised of base 41. Base 41 may be comprised of a rigid or flexible polymer including but not limited to polypropylene or ABS. Base 41 may be about 0.25 inches (6.35 mm) or less in thickness and may be opaque, translucent, transparent or a combination thereof. Base 41 may have a length to width ratio between about 1:1 to about 2:1. It is desirable that the width of base 41 be sufficient to provide stability of the cleaning implement 10 while in use.

[0039] Base 41 of cleaning head 30 may be connected to handle 20 in any number of different ways, non-limiting examples of which include utilizing one or more snaps and/or one or more screws to join the parts and/or bonding the parts together such as by adhesive bonding or ultrasonic welding. Referring to FIG. 7, in one non-limiting example which displays the use of a snap, base 41 may include protrusion 412 which can be connected to a corresponding female connection (not shown) located in the lower area 22 of handle 20. Furthermore, screw 225 may be included to connect base 41 to pad 51. Referring to FIGS. 1-8, cleaning head 30 and/or pad 51 may include if desired at least one apex 413. The vertex of apex 413 forms angles .theta..sub.1 and .theta..sub.2, as shown in FIG. 1, wherein either angle can range from about 20.degree. to about 80.degree.. When present, angles .theta..sub.1 and .theta..sub.2, of cleaning head 30 may be the same as or different than angles .theta..sub.1 and .theta..sub.2, of pad 51. While not wishing to be limited by theory, it is believed that apex 413 can help facilitate cleaning by enabling a user to access hard to reach areas such as corners of the surface being cleaned. Furthermore, when implement 10 is used in conjunction with a moist cleaning sheet, apex 413 allows for enhanced delivery and penetration of the cleaning solution to the area being cleaned. This also allows for enhanced pinpoint spot cleaning.

[0040] Base 41 of cleaning head 30 may include concave area 42 which when present will typically be located near the center of base 41. Concave area 42 provides a convenient area for the knuckles of the user when the implement 10 is in use. Concave area 42 may be of any shape including but not limited to oval shaped. In one non-limiting example, concave area 42 has a depth of approximately 0.50 inches (13 mm), a length of approximately 4 inches (10 cm) and a width of approximately 3 inches (8 cm).

[0041] Cleaning implement 10 may include attachment structure 43. Attachment structure 43 can be formed as part of cleaning implement 10 or can be formed separately and applied to cleaning implement 10. Attachment structure 43 may be included with cleaning head 30, handle 20, or a combination thereof. Referring to FIGS. 1-8, in one non-limiting example, base 41 of cleaning head 30 may include attachment structure 43 for receiving and retaining a cleaning sheet. Examples of attachment structure 43 include but are not limited to VELCRO.RTM., magnets, tabs, adhesives, hooks, grippers, and the like. Attachment structure 43 which may also be used with the present invention is disclosed in U.S. Pat. No. 6,484,346 issued to Kingry et al. on Nov. 26, 2002; U.S. Pat. No. 6,651,290 issued to Kingry et al. on Nov. 25, 2003; and U.S. Pat. No. 6,305,046 issued to Kingry et al. on Oct. 23, 2001.

[0042] Cleaning head 30 may also include pad 51 as shown in FIGS. 1-8. Pad 51 can be joined to the bottom of cleaning head 30 by any suitable joining means. For example, pad 51 can be joined to the bottom with one or more snaps. Additionally, pad 51 can be adhesively joined. In another non-limiting embodiment pad 51 can be joined to the bottom by ultrasonic welding. If desired, pad 51 could optionally be removable and/or interchangeable. For instance, in one non-limiting example, pad 51 could be interchanged with another pad, a brush, adhesive surface, some other type of cleaning surface, or a combination thereof.

[0043] Pad 51 may be made of a polymer such as polypropylene or ABS. If a polymer is used, it can be opaque, translucent, transparent, or a combination thereof. Pad 51 may also be made from foam such as polyethylene or ethylene vinyl acetate ("EVA"). Typically the foam utilized for this purpose is a closed cell foam. While not wishing to be bound by theory, it is believed that the closed cell foam will tend not to retain moisture as readily as an open cell foam hence reducing the chances of forming mold and mildew.

[0044] Pad 51 can be flat, convex, concave, or a combination thereof. If pad 51 is convex or concave, the height differential would be determined by measuring the difference between the lowest point on pad 51 and the highest point on pad 51. The height differential can range from about 0 mm to about 20 mm which would be determined by measuring the difference between the lowest point on the outwardly facing bottom of pad 51 and the highest point on the outwardly facing bottom pad of 51. While not wishing to be bound by theory, it is thought that a convex surface in contrast to a flat surface may allow for more efficient use of a cleaning sheet thereby maximizing delivery of the cleaning solution to the fabric.

[0045] If comprised of foam pad 51 may have an Indentation Force Deflection ("IDF") of at least about 30 newtons as measured in accordance with ASTM D5672-03. While not wishing to be bound by theory, it is believed that an IDF of at least about 30 Newtons will allow pad 51 to deflect less than the surface being cleaned therefore enhancing the effectiveness of implement 10.

[0046] If desired, all or some portion of the outwardly facing surface of pad 51 can be modified to increase the coefficient of friction. While not wishing to be bound by theory, it is thought that the increase in the coefficient of friction may enhance contact of the implement 10 to the surface being treated thereby facilitating soil removal from the treated surface. Furthermore, when implement 10 is used in conjunction with a cleaning sheet, it is believed that the increase in the coefficient of friction may assist with minimizing slippage of the cleaning sheet from implement 10. The outwardly facing surface of pad 51 can be modified by texturing, TPE, soft touch paint, etc. Referring to FIG. 5, the outwardly facing surface of pad 51 may also include indicia 52, a non-limiting example of which includes an array that creates an image or pattern such as raised and/or recessed areas. While not wishing to be limited by theory, it is believed that when used in conjunction with a cleaning sheet, pad 51 which includes these indicia 52 provide a signal to a user. One non-limiting example of a signal includes a visual signal which can for instance signal the status/condition of the cleaning sheet, (i.e.; provide an indication of the soil level of the cleaning sheet and/or when the cleaning sheet needs to be changed), and/or send a message to a consumer such as provide use instructions, and/or indicate a trade name, logo, aesthetic design, and/or some other message.

[0047] Referring to FIGS. 1-2 and 4-7, implement 10 may also include angled surface 60 on at least one end of handle 20 and/or cleaning head 30. While not wishing to be bound by theory, it is thought that angled surface 60 can allow for enhanced spot treatment/scrubbing of a fabric surface. Furthermore, when used in conjunction with a moist cleaning sheet, it is believed that angled surface 60 will allow for enhanced delivery of the cleaning solution upon contact of the cleaning sheet with the fabric surface. Angled surface 60 may be comprised of a foam or a rigid or flexible polymer non-limiting examples of which include polypropylene and/or ABS. Angled surface 60 may be smooth. Alternatively, some portion or all of angled surface 60 may be textured and/or include some other type of structure which increases the coefficient of friction of this surface. Referring to FIG. 6, in one non-limiting embodiment, the bottommost point of the outwardly facing side of pad 51 and the topmost point of angled surface 60 form angle a as shown in FIG. 6 wherein angle a may range from about 10.degree. to about 120.degree.; or from about 20.degree. to about 110.degree.; or from about 40.degree. to about 100.degree.; or from about 70.degree. to about 90.degree.. Angled surface 60 may be flat, convex, concave, or a combination thereof.

The cleaning sheet may be used dry, may be moistened by the user, may be provided to the user in the form of a moistened cleaning sheet that is premoistened with a cleaning solution during manufacturing, and/or may be provided as a wet or dry cleaning sheet which includes a microencapsulated cleaning solution and/or other actives which rupture upon use thereby delivering the cleaning solution and/or other active to the surface to be treated. Non-limiting examples of suitable cleaning sheets useful with the present invention include those disclosed in U.S. Patent Application Ser. No. 60/606,820 filed on Aug. 1, 2004; U.S. Pat. No. 6,561,354 issued to Fereshtehkhou et al. on May 13, 2003; and WO 2004/080265 published in the name of Hofte et al. on Sep. 23, 2004. Additionally, other forms of cleaning sheets that could be used include but are not limited to baby wipes, cleaning wipes, towelettes, or the like. Referring to FIGS. 1-6, the cleaning sheet can be attached to attachment structure 43 of cleaning head 30 so as to substantially cover pad 51. Angled surface 60 may also be covered in whole or in part by the cleaning sheet. In addition, the cleaning sheet may be apertured or not apertured.

[0049] The cleaning implement may be provided in a package (not shown) such as a box or carton having a window and/or opening so as to allow the user to view and/or touch at least some portion of the cleaning implement prior to use without having to remove the cleaning implement from the package. In one non-limiting embodiment, in addition to the cleaning implement, the package may also include one or more cleaning sheets. Alternatively, the cleaning sheets could be packaged and/or provided separately from the cleaning implement.

Use Identifiers

[0050] Use identifiers (not shown), may be used if desired in order to identify that the cleaning implement and/or cleaning sheet is used for fabric. In addition to or alternatively, one or more use identifiers can also be utilized for example to indicate the types and/or forms of fabrics the cleaning implement and/or cleaning sheets may be used on.
