Is a side edge portion of the cleaning sheet 6. Then, if a large amount of dust or dust adheres to the cleaning sheet 6 covering the bottom surface 3 of the base material 1 and its cleaning ability deteriorates, it is turned over.
Or replace with a new cleaning sheet. In the present invention, the side edge portion of the cleaning sheet is simply stopped by the adhesive force of the pressure-sensitive adhesive layer, so that the cleaning sheet can be easily peeled and replaced.

In the above example, the base material 1 is plate-shaped, but it is not necessarily plate-shaped as long as it has a bottom surface, and may be, for example, a semi-cylindrical shape with a raised upper surface. The base material 1 may be integrally molded with a synthetic resin such as ABS resin as in the above example, or may be an elastic body, for example, a bottom surface component made of synthetic rubber fitted therein. In the above example, the pressure-sensitive adhesive layer was provided at two elongated locations along the inside of the front and rear edges of the upper surface of the base material, but the pressure-sensitive adhesive layer may be provided at four locations at the four corners of the top surface of the base material. , 6 along the inside of the front and back edges of the adhesive layer
It may be provided at 10 places, or may be provided over the entire upper surface of the base material.

When the base material 1 is molded, the pressure-sensitive adhesive layer can be formed by the cast molding method to form the pressure-sensitive adhesive layers 4 and 5. In addition, the pressure-sensitive adhesive is molded into a sheet shape, cut into a desired shape, and the pressure-sensitive adhesive layer 4 is adhered and fixed to a desired portion of the base material with an adhesive,
5 may be provided. The pressure-sensitive adhesive is, for example, a urethane-based pressure-sensitive pressure-sensitive adhesive produced by reacting a urethane prepolymer having a free isocyanate group at a molecular end obtained by reacting a polyol with an excess of organic isocyanate, with a polyol. .

This urethane-based pressure-sensitive adhesive itself is known (for example, JP-A-51-12828, JP-A-53-31192, JP-A-62-106978). Adhesiveness can be adjusted by the types and proportions of polyol and organic isocyanate used. When dust or dust adheres to the surface of the pressure-sensitive adhesive and loses its tackiness, the tackiness of the pressure-sensitive adhesive is lost by wetting it with water, and the dust or dust can be easily removed. When it is dried, it becomes tacky again. The pressure-sensitive adhesive constituting this pressure-sensitive adhesive layer is usually 18 to 190 gf / 10 mm (JI
A urethane-based pressure-sensitive adhesive in the range of S Z 02378.3.1 180 degree peeling method) is used. In addition, a polymeric substance having the same adhesive properties as described above, such as polyvinyl chloride, has a molecular weight of about 80 sebacic acid and ethylene glycol.
It is also possible to use a composition in which a condensed polyester of No. 00 is blended as a plasticizer (Japanese Patent Publication No. 53-43534).

In the above example, the pressure-sensitive adhesive layer is provided on the upper surface of the substrate 1, but the invention according to claim 2 of the present invention is
This adhesive layer is provided on the bottom surface of the substrate. FIG.
Is a bottom view of the base material showing an example thereof, and FIG. 6 is a cross-sectional view taken along line BB. Reference numeral 3 denotes the bottom surface of the base material 1. Reference numeral 8 is an adhesive layer provided on the peripheral portion. In this invention, since the adhesive layer 8 is provided on the bottom surface of the base material 1, the adhesive layer 8 on the bottom surface is provided.
The cleaning sheet can be attached directly by using the adhesive force. Therefore, it is not necessary to bend the side edge portion of the cleaning sheet to bring it to the upper surface of the base material as in the invention according to claim 1,
Since the bottom surface of the cleaning sheet is sufficient, it can be small and economical. In this example, it is provided on the peripheral portion of the bottom surface, but it may be provided at an arbitrary location on the opposing peripheral portion, on the central portion of the bottom surface, or on the entire bottom surface. The cleaning sheet is attached / detached in the same manner as described above.

According to the third aspect of the present invention, an adhesive layer is provided on the upper surface and the bottom surface of the base material. FIG.
It is sectional drawing about the invention of Claim 3 corresponding to FIG. 3 which concerns on invention of Claim 1, and FIG. 6 which concerns on invention of Claim 2. Adhesive layers 4, 5 are provided on the upper surface 2 of the base material 1, and an adhesive layer 8 is provided on the peripheral portion of the bottom surface 3 of the base material 1. The central portion of the cleaning sheet is adhesively fixed to the adhesive layer 8 on the bottom surface 3 of the base material 1, and the side edge portions of the sheet are adhesively fixed to the adhesive layer 4, 5 on the upper surface of the base material 1. The bottom surface 3 of 1 can be covered more firmly with a cleaning sheet. In this example, the pressure-sensitive adhesive layer is provided on the peripheral portion on a part of the upper surface and a part of the bottom surface of the base material, but the location of the adhesive layer may be provided on the entire surface. The cleaning sheet is attached / detached in the same manner as described above.

In the cleaning tool of the present invention, when the cleaning sheet dust, dust or dust adheres to the surface of the pressure-sensitive adhesive layer during use and loses the pressure-sensitive adhesive property, the pressure-sensitive adhesive layer is washed with water. Since the adhesive property of the adhesive layer disappears during this washing with water, dust on the cleaning sheet, dust, or dust adhering to the surface of the adhesive layer can be easily removed. Then, after washing with water and drying, the tackiness of the pressure-sensitive adhesive layer is restored.

[0015]

According to the present invention, since the pressure-sensitive adhesive layer is provided on the upper surface of the plate-shaped base material, both side edges of the cleaning sheet covering the bottom surface of the base material are bent upward, and the side edges are respectively placed on the upper surface. Since it can be fixed simply by adhering it to the adhesive layer, the cleaning sheet can be attached to the base material very easily. Further, the cleaning tool of the present invention can be used for cleaning a floor or the like with a handle attached, but since it can be downsized, it can also be used for cleaning a desk or the like. Then, if a large amount of dust or dust adheres to the cleaning sheet covering the bottom surface of the base material and its cleaning ability deteriorates, it is necessary to turn it over or replace it with a new cleaning sheet. Since the side edge portion of is simply stopped by the adhesive force of the adhesive layer, it can be easily peeled and replaced. Also, during use, if the cleaning sheet dust, dust, or dust adheres to the surface of the adhesive layer and loses the adhesiveness, the adhesive layer is washed with water and dried to re-attach the adhesive layer. Since it can be made sticky, it can be used for a long period of time.
