[0030] A first embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a cleaning tool, and it comprises a grip portion 2 and a scrubbing portion 3 attached to an end portion 21 of the grip portion 2.

[0031] The scrubbing section 3 includes six laminated sheets of nonwoven fabric 4 and a lamination tool 5 for laminating the six sheets of nonwoven fabric 4 together. The six laminated nonwoven fabrics 4 are formed from one first nonwoven fabric 41 on each side as shown in FIG. 4, and four second nonwoven fabrics 42 in the center as shown in FIG.

[0032] Each of the six nonwoven fabrics 4 has four through-holes 43 formed by V-shaped slits 43a, each V-shaped slit 43a having an angle of 60 degrees and a length of 9 mm, and the four slits 43a are arranged at approximately equal intervals in the central part of the planar shape 44 of the nonwoven fabric 4. As shown in Figures 4(a) and 5(a), each of the six nonwoven fabrics 4 has a planar shape 44 that is contoured to include a rectangular portion 45 on the grip handle 2 side and a convex curved portion 46 on the anti-grip handle side, which is the end of the scrubbing part 3, consisting of a lower arc portion 46a and an upwardly protruding semicircular portion 46b.

[0033] Furthermore, by forming the flat shape 44 of the nonwoven fabric 4 into a convex curved portion 46 on the side opposite the grip handle, which is the end of the scrubbing portion 3, it has a shape suitable for cleaning dirt from the curved surfaces of a toilet bowl or a bathroom bathtub. The first nonwoven fabric 41 is made of nylon fibers and polyester fibers, and the second nonwoven fabric 42 is made of nylon fibers and carries abrasive particles made of silica sand by impregnation adhesion.

[0034] The second nonwoven fabric 42 made of nylon fiber in the center provides excellent abrasion resistance, while the first nonwoven fabrics 41 made of nylon and polyester fiber on both sides provide excellent rigidity and shape retention. In addition, the second nonwoven fabric 42 carries abrasive particles so that stubborn dirt can be removed.

[0035] The lamination device 5 is made of polypropylene resin and, as shown in Figure 2, is a plate-like member approximately 10 mm wide and shaped to follow the arrangement of the four V-shaped slits 43a formed in the nonwoven fabric 4, and is equipped with a rod side member 51 having upright rod-shaped portions 52 that are inserted into each of the four V-shaped slits 43a, and a locking side member 53 having locking holes 54 formed therein. The rod side member 51 is arranged on one outer side of the stacked nonwoven fabrics 4, and the locking side member 53 is arranged on the other outer side of the stacked nonwoven fabrics 4, and each of the ends 52a of the rod-shaped portion 52 is inserted therethrough and locked.

[0036] The rod-shaped portion 52 of the rod side member 51 is inserted into each slit 43a of the six sheets of nonwoven fabric 4 and engaged with the engaging hole 54 of the engaging side member 53, so that the cut surface 47 of the stacked nonwoven fabrics 4 forms the cleaning surface of the scrubbing portion 3. In this way, by using the cut surface 47 of the nonwoven fabric 4 as the cleaning surface of the scrubbing part 3, cleaning can be performed in a short time while improving the dirt removing performance.

[0037] The length of the portion of the rod-shaped portion 52 of the rod side member 51 that penetrates the nonwoven fabric 4 is formed to be 20 mm, which is smaller than the thickness of 60 mm of the six sheets of nonwoven fabric 4 in a stacked state when not secured by the stacking device 5. The nonwoven fabric 4 is held in place by the lamination tool 5 in a compressed and laminated state, so that the rod side member 51 and the locking side member 53 do not protrude outward from the first nonwoven fabric 41 on the outside of each of the laminated nonwoven fabrics 4. This prevents the lamination tool 5 from hitting the object to be cleaned, such as a toilet bowl, allowing for good cleaning.

[0038] The V-shaped slits 43a formed in each of the nonwoven fabrics 4 can be easily formed, and resistance is generated in the insertion of the rod-shaped portion 52, so that the insertion position of the rod-shaped portion 52 in the V shape is fixed, resulting in a smooth finish to the scrubbing portion 3. As shown in Figure 3, the rod side member 51 and the locking side member 53 are each formed with an engagement protrusion 55 that engages with the engagement portion 22 formed on the end portion 21 of the grip handle portion 2, so that the engagement protrusion 55 of the stacking device 5 is engaged with the engagement portion 22 of the grip handle portion 2.

[0039] The grip handle 2 and the lamination tool 5 are made of polypropylene resin, and when the engagement protrusion 55 of the lamination tool 5 engages with the engagement portion 22 of the grip handle 2, the engagement is maintained by the action of the elastic claw 55a so that it cannot be released. Next, the process for manufacturing the scrubbing part 3 will be described with reference to Figs. 6(a) to (d).

[0040] The scrubbing portion 3 is manufactured by first preparing the rod side member 51 and the locking side member 53 of the lamination tool 5, as well as the first nonwoven fabric 41 and the second nonwoven fabric 42, by molding and processing them, and then using a manual lamination device 6 to laminate the nonwoven fabric 4 with the lamination tool 5. As shown in FIG. 6(a), the lamination device 6 has a lower mold 62 for the scrubbing part 3 at the center of a base 61 and The side of the base 61 is provided with a support portion 65 which rotatably supports a rotating operating rod 64 to which an upper mold 63 is fixed. The support portion 65 is partially made of metal material, with the remainder being made of wood.

[0041] As shown in Figure 6(b), the rod side member 51 of the lamination device 5 is set in the lower mold 62 of the lamination device 6, and as shown in Figure 6(c), the six sheets of nonwoven fabric 4 in a stacked state are set in the lower mold 62 and the locking side member 53 of the lamination device 5 is set on top of the nonwoven fabric 4. Then, as shown in FIG. 6(d), by rotating the rotating operating rod 64 of the stacking device 6 to press the upper mold 63 against the locking side member 53, with the nonwoven fabric 4 stacked, each rod-shaped portion 52 in the rod side member 51 is inserted into each locking hole 54 in the locking side member 53, and the end portion 52a of the rod-shaped portion 52 is pressed against and locked.

[0042] In this way, by manually operating the lamination device 6, the nonwoven fabric 4 is compressed and laminated and locked by the lamination tool 5, and the scrubbing portion 3 can be manufactured in a state in which the rod side member 51 and the locking side member 53 do not protrude outward from the first nonwoven fabric 41 on the outside of each of the laminated nonwoven fabrics 4. As shown in FIG. 2, an engaging claw portion 56 is cut and raised on the rod side member 51 of the laminate 5, and an engaging hole portion 57 into which the engaging claw portion 56 engages is formed in the locking side member 53. By pressing the upper mold 63 of FIG. 6(d) against the locking side member 53, the engaging claw portion 56 engages with the engaging hole portion 57.

[0043] In FIG. 1, reference numeral 23 denotes a hanging hole provided at the upper end of grip handle portion 2, and reference numeral 24 denotes a flange portion for engaging with an engaging portion of a storage case (not shown) when cleaning tool 1 is stored. Next, a second embodiment of the present invention will be described with reference to FIGS.

[0044] The cleaning tool 1 of embodiment 2 has the configuration of the through portion 43 in the nonwoven fabric 4 of the cleaning tool 1 of embodiment 1 changed from the V-shaped slit 43a in embodiment 1 to a circular through hole 43b, and the configuration that differs from embodiment 1 is described below. The through holes 43b in embodiment 2 have a diameter of 6 mm, and the arrangement of the four through holes 43b is approximately equally spaced in the central part of the planar shape 44 of the nonwoven fabric 4, similar to the arrangement of the V-shaped slits 43a in embodiment 1.

[0045] Furthermore, since the through-holes 43 formed in each of the nonwoven fabrics 4 are circular through-holes 43b, it takes time to remove the punched nonwoven fabric, but it is easy to insert the rod-shaped portion 52 therethrough. Next, modifications of the first and second embodiments of the present invention will be described.

[0046] In the above embodiment, the four central second nonwoven fabrics in the stacked nonwoven fabrics are configured to carry abrasive particles, but the stacked nonwoven fabrics may also be configured so that the second nonwoven fabrics do not carry abrasive particles.

[0047] The second nonwoven fabric, which does not carry abrasive particles, is formed from nylon fibers and, since it does not carry abrasive particles, its dirt removing performance is inferior to that of the embodiment, but the risk of damaging the surface to be cleaned is reduced. In order to distinguish between a cleaning tool having abrasive particles carried on the second nonwoven fabric according to the embodiment and a cleaning tool having no abrasive particles carried on the second nonwoven fabric according to the above-mentioned modified example, the second nonwoven fabric of each cleaning tool is colored in a different color.

[0048] In this way, when cleaning tools with different cleaning capabilities that are difficult to distinguish from the outside are sold as a series, it is easy for traders such as sellers and consumers (users) to distinguish between them. In the above-described embodiment, the planar shape of the nonwoven fabric is formed into an outline consisting of a rectangular portion on the grip handle side and a convexly curved portion on the opposite side to the grip handle, but the nonwoven fabric is not limited to this planar shape and can have various planar shapes such as an ellipse, a circle, a polygon, etc.

[0049] In addition, in the above embodiment, the six nonwoven fabrics are formed of one first nonwoven fabric on each side and four second nonwoven fabrics in the center, but the number of nonwoven fabrics can be any number between 4 and 10. In addition, in the above embodiment, the first nonwoven fabric is formed from nylon fibers and polyester fibers, and the second nonwoven fabric is formed from nylon fibers, but both the first nonwoven fabric and the second nonwoven fabric can be nonwoven fabrics formed from various materials.

[0050] Furthermore, the nonwoven fabric is held in place by the lamination device in a compressed and stacked state, so that the rod side member and the locking side member do not protrude outward from the first nonwoven fabric on the outside of each of the stacked nonwoven fabrics; however, the nonwoven fabric can also be in a compressed and stacked state in which the rod side member and the locking side member protrude outward from the first nonwoven fabric. In the above embodiment 1, the through portion 43 formed in the nonwoven fabric 4 is a V-shaped slit 43a, but it can also be a U-shaped slit 43c as shown in Figure 9(a), a straight slit 43d as shown in Figure 9(b), a T-shaped slit 43e as shown in Figure 9(c), or a cross-shaped slit 43f as shown in Figure 9(d).

[0051] The dimensions of the U-shaped slit 43c, the straight slit 43d, the T-shaped slit 43e and the cross-shaped slit 43f shown in Figures 9(a) to 9(d) are formed to be large enough to allow the rod-shaped portion 52 of the rod side member 51 of the laminate 5 to pass through. In the above-described embodiment 2, the through portion 43 formed in the nonwoven fabric 4 is a circular through hole 43b, but it can also be a square through hole 43g as shown in FIG. 10(a) or a hexagonal through hole 43h as shown in FIG. 9(b).
