[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning cloth, and more particularly to a cleaning cloth suitable for a cleaning tool for wiping and cleaning a floor surface or the like by supporting the cleaning cloth on a surface.

[0002]

2. Description of the Related Art In recent years, various cleaning tools have been proposed for cleaning floor surfaces such as floors, tatami mats, and cushion floors inside buildings and surfaces to be cleaned such as various electric appliances and furniture surfaces. And the applicant of the present application is, for example, Japanese Patent Application No.
No. 151063 and Japanese Patent Application No. 7-206635 propose a cleaning tool in which a support arm is connected to a main body that holds a cleaning cloth.

In the cleaning tool by the applicant of the present application, a cleaning cloth is held so as to be wound around a main body having a substantially rectangular parallelepiped shape, and a supporting arm rotatably supports the main body. According to these cleaning tools, if the main body is appropriately separated from the floor surface and rotated during cleaning, the cleaning portions provided on the respective end surfaces of the main body can sequentially slide-contact with the surface to be cleaned through the cleaning cloth. , The cleaning can be continued until dirt is accumulated on the entire area of one side of the cleaning cloth. Note that the cleaning cloth is, for example, a non-woven fabric, and dust and the like on the surface to be cleaned are taken in between the fibers to be removed.

[0004]

By the way, in general, a cleaning tool using a non-woven fabric as a cleaning cloth removes solid dust such as bread crumbs, confectionery scraps, paper chips, and sand from the surface to be cleaned because of its fiber structure. There is a problem that you cannot do it. In order to solve this problem, the applicant of the present application has proposed a cleaning cloth having an adhesive surface formed at a position corresponding to at least one of the cleaning parts on the assumption that the cleaning cloth is applied to the cleaning tool described above. (Japanese Patent Application No. 7-299226: Conventional example). According to this conventional example, the above-mentioned solid dust can be removed from the surface to be cleaned by pressing the adhesive surface against the surface to be cleaned.

However, in this conventional example, since the main body needs to be rotated each time in order to remove the solid dust from the surface to be cleaned, the cleaning work is complicated, and the user has requested improvement. . The present invention has been made in order to meet such a conventional demand, and an object thereof is to provide a cleaning cloth that can easily remove solid dust that cannot be captured between fibers of a nonwoven fabric from a surface to be cleaned.

The feature is that they are arranged substantially in parallel.

In this case, as the cleaning cloth, a non-woven fabric conventionally used as a cleaning cloth can be used. The recess may be formed by, for example, embossing a predetermined position of the cleaning cloth. As the recesses, circular recesses having a predetermined diameter may be formed in spots on the surface of the cleaning cloth, or may be formed in mutually parallel grooves, concentric circles, lattices, radials, spirals, or the like. May be. On the other hand, as the adhesive surface, for example, an adhesive capable of adhering solid dust to the bottom of the embossing may be applied. And, the step size between the adhesive surface and the surface of the cleaning cloth is the surface of the adhesive surface when the cleaning cloth is compressed in the thickness direction by the user of the cleaning tool pressing the cleaning tool against the surface to be cleaned. It may be appropriately set so that the surface abuts the surface to be cleaned.

In the invention according to claim 1 of the present invention as described above, when the user operates the cleaning tool with a force less than a certain level, the adhesive surface is housed from the surface of the cleaning cloth to the bottom side of the recess. As a result, it is possible to perform a normal cleaning in which dust having a certain size or less is taken in between the fibers of the cleaning cloth. On the other hand, for solid dust that cannot be captured between the fibers of the cleaning cloth, the user presses the cleaning tool against the surface to be cleaned with a certain force, and the cleaning between the cleaning part and the surface to be cleaned is performed. The cloth will be compressed in the thickness direction. At this time, the adhesive surface is
It relatively projects toward the surface of the cleaning cloth and adheres to the surface to be cleaned and solid dust. Then, when the user relaxes the force and the cleaning cloth recovers the initial thickness, the adhesive surface keeps the solid dust adhering inside the recess and the normal cleaning can be resumed. That is, in the invention described in claim 1, if the user performs a very simple operation of pressing the cleaning tool against the surface to be cleaned, the adhesive surface can remove the solid dust from the surface to be cleaned. The purpose is achieved.

The invention according to claim 2 has a first face material and a second face material that are bonded to each other, and a through hole is formed in the thickness direction of the first face material, and An adhesive surface is provided on the surface of the second face material, and the through hole and the adhesive surface are arranged at positions corresponding to each other. In this case, as the first face material, a large number of through holes having an arbitrary shape may be formed at predetermined positions at predetermined positions of a non-woven fabric conventionally used as a cleaning cloth, or linear or concentric circles parallel to each other may be formed. It is also possible to form through-holes having a circular shape, a grid shape, a radial shape, a spiral shape, or the like. On the other hand, as the second surface material, an adhesive may be applied to the surface of the non-woven fabric, or a rubber-based, acrylic-based,
An adhesive material such as silicon may be formed into a sheet.

In the invention described in claim 2, when the first face material and the second face material are adhered to each other, the through hole of the first face material is covered with the second face material and automatically. A recess is formed on the surface of the cleaning cloth, and an adhesive surface is provided inside the recess. Therefore, claim 2
In the invention described in, for example, after forming a recess by embossing on the surface of the nonwoven fabric, without relying on the extremely complicated manufacturing method of applying the adhesive to a predetermined thickness,
The desired cleaning cloth can be easily obtained.

Further, the invention according to claim 3 is characterized in that the first face material is arranged on the front and back sides of the second face material. In the invention described in claim 3, since the front and back of the cleaning cloth have the same shape, both the front and back can be effectively used.

The cleaning cloth 10 comprises a pair of first face materials 11, 11.
And a second face material 12 sandwiched between these first face materials 11, 11. The first face material 11, 11 and the second face material 12 are attached to each other with their peripheral edges aligned. The first face material 11 is a non-woven fabric formed in a substantially rectangular shape, is capable of contracting in the thickness direction, and takes in dusts and the like having a size smaller than a certain value between the fibers. A large number of through holes 13 are formed on the surface of the first face material 11 at predetermined intervals. These through holes 13 have a circular shape having a predetermined diameter, and the first face material 11
Through in the thickness direction. On the other hand, the second face material 12 is a nonwoven fabric formed in the same shape and the same size as the first face material 11, and is capable of contracting in the thickness direction. The second face material 12 is coated on both the front and back sides with an adhesive having a certain size or more and capable of adhering solid dust such as bread crumbs, confectionery scraps, paper chips, and sand. The adhesive is the first surface material 11
Different desired color may be used.

In this cleaning cloth 10, the second face material 12 is partially exposed from the through holes 13 of the first face material 11, 11. Therefore, the cleaning cloth 10 has the concave portion 14 formed on the surface by the through hole 13, and the adhesive surface 15 formed by the second face material 12 is provided inside the concave portion 14. . The adhesive surface 15 is arranged stepwise and substantially parallel to the surface of the cleaning cloth 10. When manufacturing the cleaning cloth 10, the second face material 12
