[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an embodiment of the cleaning tool of the present invention, FIG. 2 is a perspective view showing an assembled state of the cleaning tool, and FIG. 3 is a view for explaining a method of attaching a foam to the cleaning tool. FIG. 4 is a perspective view, and FIG. 4 is a sectional view taken along the line IV-IV in FIG.

First, as shown in FIG. 1, a cleaning tool 1 of the present embodiment has a sheet-like melamine foam 10 obtained by slicing a block of melamine foam into a sheet. The shape and size of the sheet-shaped melamine foam 10 are not particularly limited, and may be any shape and size that can be attached to the cleaning tool body 20 described later. In this example, the foam is formed in a rectangular shape in order to increase the yield, and is slightly larger than the mounting surface 241 of the cleaning tool body 20. The thickness t of the sheet-shaped melamine foam 10 is not particularly limited. For example, the thickness t is about 1 to 3 mm. It can be said that it is preferable.

The structure and size of the manufacturing tool main body 20 for mounting the sheet-shaped melamine foam 10 are not particularly limited. In this example, the cleaning tool main body 20 is composed of two members 22 and 24 that can be disassembled, and the sheet-like melamine foam 10 is sandwiched between them. For example, as shown in FIG. 1, the member 22 is formed in a bowl shape, and the handle 221 is formed on the upper surface, so that the user can grip and clean the handle 221. On the other hand, with respect to the member 24, an edge 242 is formed around the periphery of the member 22 so as to fit with a slight gap inside the outer peripheral edge of the member 22. The mounting surface 241 is configured.

As shown in FIG. 4, when the members 22 and 24 are fitted together, gaps S1 and S2 are formed between the two, and the peripheral edge of the sheet-like melamine foam 10 is folded and sandwiched in these gaps. . Although not shown, each of the members 22 and 24 is formed with several engagement pieces, whereby the two pieces 22 and 24 are locked, and the two pieces are released by releasing the engagement pieces. , 24 can be disassembled.

In order to mount the sheet-shaped melamine foam 10 on the cleaning tool main body 20, the two members 22 and 24 are disassembled as shown in FIG. The mounting surface 241 of the member 24 is placed, and the four sides of the sheet-like foam 10 protruding from the member 24 are folded back so as to cover the edge 242 of the member 24. In this state, the member 22 is put on from above, and a locking piece (not shown) is locked to fix the sheet-shaped melamine foam 10 between the members 22 and 24.

FIG. 3 is a perspective view showing a state where the cleaning tool 1 is assembled. The main surface (here, 10 b shown in FIG. 4) of the sheet-like melamine foam 10 located on the lower surface of the cleaning tool body 20 removes dirt. Provides a cleaning surface for removal.

A melamine foam is a foam based on a condensation product of a compound having an amino group and formaldehyde, and is a porous body having a three-dimensional network structure. The three-dimensional network structure is formed by relatively fine single fibers, and the single fibers have a relatively large length with respect to their width.

For this reason, the volume ratio of the cavity (pore) of the cell is high, and it is easy to impregnate with water or the like. In addition, since the foam itself is made of fine fibrous material, rubbing the surface of plastic or the like with this melamine foam exerts a polishing effect, and removes dirt firmly adhered to the surface of the plastic product. At the same time, the surface of the plastic product becomes smooth and the gloss regenerates. Therefore, dirt can be removed without using a detergent or the like, and the surface can be shiny.

In particular, in the cleaning tool 1 of the present embodiment, such a melamine foam is sliced and used in a sheet shape. Therefore, if one side (10b in the example shown in FIG. 4) becomes dirty, the members 22 and 24 are disassembled. Then, the sheet-like melamine foam 10 can be removed, turned over, and re-attached (in this case, the cleaning surface is 10a). Therefore, most of the surface of the sheet-like melamine foam 10 is used as a cleaning surface. It can be used and cost reduction can be expected.

Although not particularly limited, in order to prevent the sheet-shaped melamine foam 10 from being broken during cleaning or the like, the back surface of the sheet-shaped melamine foam (10a in the example shown in FIG. 4) is used. Alternatively, a thin sheet of nonwoven fabric, paper, cloth, polyurethane foam, or the like can be attached using an adhesive or the like. In this case, only one surface can be used as the cleaning surface, but the strength of the sheet-shaped melamine foam 10 increases, so that the melamine foam 10 does not break during cleaning or replacement.

The cleaning tool 1 of the above-described embodiment is preferably used particularly when the object to be cleaned is a flat surface. However, when the object to be cleaned is a hard-to-reach place such as the back of a toilet, for example, A cleaning tool 1 as shown in FIG. 5 can be used. The cleaning tool 1 is formed by molding a melamine foam into a rod shape and inserting the melamine foam into the cleaning tool body 20, and the tip of the melamine foam body 10 serves as a cleaning surface. When the tip of the rod-shaped melamine foam 10 becomes dirty, the rod-shaped melamine foam 10 is cut and the rod-shaped melamine foam 10 is taken out.

The embodiments described above are described to facilitate understanding of the present invention, and are not described to limit the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
