DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning sheet for wiping dirt and dust on a floor.

[0002]

2. Description of the Related Art Heretofore, as this kind of sheet, those obtained by raising a nonwoven fabric, those obtained by impregnating a nonwoven fabric with an oil agent, those obtained by applying a pressure-sensitive adhesive to a sheet serving as a base material, and the like are well known.

[0003]

Among the above-mentioned known cleaning sheets, those brushed with a non-woven fabric have a good sliding property with respect to the floor surface, but are inferior in the ability to hold relatively heavy debris such as sand particles. It is not suitable for wiping such debris.
Although the nonwoven fabric impregnated with the oil improves the holding power of the dust, it may not be enough. Although the cleaning sheet using the adhesive has excellent dust holding power, it does not slide well on the floor due to its adhesiveness. In addition, the cleaning sheet may stick to the hand and may be difficult to handle at times.

[0004] Therefore, an object of the present invention is to provide a cleaning sheet which is excellent in holding power of dust, has good sliding on a floor surface, and is easy to handle without sticking to hands.

[0005]

In order to solve the above-mentioned problems, the present invention is based on a cleaning sheet for wiping dirt and dust on a floor , and at least one of both sides of the sheet is provided with a cleaning sheet. A first surface area; and a second surface area which is located above and separated from the floor surface when the first surface area comes into contact with the floor surface, and the second surface area captures dust by adhesion. Do
An adhesive surface, wherein the first surface area is weaker than the second surface area
Such a sheet having an adhesive or non-adhesive surface.
Where the present invention is characterized in such a premise, before
The elasticity in the thickness direction of the first surface area is higher than that of the second surface area.
It is also higher .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the cleaning sheet according to the present invention will be described below with reference to the accompanying drawings.

A cleaning sheet 1 shown in a partially cutaway perspective view in FIG. 1 has a base sheet 2 made of non-woven fabric, an intermediate sheet 3 whose upper and lower surfaces are adhesive, and an adhesive sheet weaker than the sheet 3 or And a top sheet 5 of a mesh ground having no tackiness. The top sheet 5 has a large number of through holes 4 and is joined to the base sheet 2 via the intermediate sheet 3, and the through holes 4 have an adhesive surface on the upper surface side of the intermediate sheet 3. The illustrated intermediate sheet 3 and top sheet 5 overlap each other in substantially the same shape and size, and the base sheet 2
5 has the same length, but is wider and has side edges 6 extending from the left and right side edges of the sheets 3 and 5.

FIG. 2 is a perspective view of the cleaning sheet 1 attached to the floor cleaning tool 11. The device 11 includes a plate 13 and an arm 14 pivotally attached to the plate 13. The cleaning sheet 1 is applied to the lower surface of the plate 13, the side edge 6 is folded on the upper surface of the plate 13, and is detachably fastened by the clip 8. The appliance 11 has the arm 14 and can wipe the floor surface with the top sheet 5 of the cleaning sheet 1.

The cleaning sheet 1 attached to the appliance 11
In this case, relatively light dust such as dust is trapped by entanglement with the nonwoven fabric fibers constituting the topsheet 5, and when the topsheet 5 is sticky, it is captured by the stickiness. Relatively heavy debris, such as sand particles, which are hardly entangled with the fibers, enter the through holes 4 of the topsheet 5 and are captured by the adhesive surface of the intermediate sheet 3 in the through holes 4. The nonwoven fabric used for the topsheet 5 may be subjected to a raising treatment, a crumpled fiber may be used to make it bulky, or an oil agent may be impregnated so as to easily catch dust. The surface sheet 5 can change the depth of the through-holes 4 depending on its thickness. However, the elasticity (cushioning property) in the thickness direction is relatively good, and the through-holes 4 are used during the use of the cleaning sheet 1. It is preferable that the adhesive surface of the intermediate sheet 3 be appropriately close to the floor surface regardless of the depth of the intermediate sheet 3. In the cleaning sheet 1, the edge 16 of the through hole 4 acts to scrape off dust attached to the floor, and the scraped dust can be captured by the through hole 4.

The top sheet 5 of the cleaning sheet 1 used in this manner has a weaker adhesiveness than that of the intermediate sheet 3 or has an adhesive property so that the surface sheet 5 can be smoothly slid on the floor surface. I haven't.

When the cleaning sheet 1 is attached to the appliance 11, if the user holds the base sheet 2 and the top sheet 5 so that the finger does not touch the intermediate sheet 3, the finger does not stick to the adhesive surface. If the cleaning sheet 1 is not to be attached to the appliance 11, the side edge 6 can be omitted, and the cleaning sheet 1 can have the same shape and the same size as the intermediate sheet 3 and the top sheet 5.

FIG. 3 is a drawing similar to FIG. 1 showing an embodiment of the present invention. In this cleaning sheet 1, a large number of disks 17 covering the intermediate sheet 3 are in contact with the floor surface instead of the top sheet 5 in FIG. The disks 17 are disposed on the upper surface of the intermediate sheet 3 so as to be spaced apart from each other in four directions.
Each disk 17 is formed by punching a nonwoven fabric or felt having a required thickness. Such a cleaning sheet 1
Compared to that of FIG. 1, in this sheet 1, when the floor is wiped, dust enters between the adjacent disks 17 and reaches the center of the sheet 1, where the side surface of the disk 17 and the intermediate sheet 3 More opportunities to be captured. Therefore, the entire area of the sheet 1 can be used efficiently.

FIG. 4 is a drawing similar to FIG. 3 showing still another embodiment of the present invention. In this cleaning sheet 1, a plurality of strips 18 extending in one direction in parallel with each other in place of the disk 17 cover the intermediate sheet 3 and come into contact with the floor surface. As the strip 18, a sheet made of a nonwoven fabric or a fiber such as a felt having a required thickness, which is cut to a required width, a filament or a split fiber having a relatively large diameter, or a bundle thereof can be used. .

In the present invention, the topsheet 5 of FIG. 1 used for covering the adhesive surface and rubbing the floor, and the disk 17 and the strip 18 of FIGS.
It is sufficient that the sheet 3 is bonded by the adhesive force of the sheet 3. The intermediate sheet 3 and the top sheet 5 are combined with the base sheet 2
If one side of the cleaning sheet 1 is dirty on both sides of
It may be turned over and used. For the base sheet 2 and the intermediate sheet 3, an appropriate sheet material can be used in addition to the illustrated example.

The cleaning sheet 1 is suitable for cleaning a floor surface, but can be used for cleaning an appropriate place such as a wall surface or a ceiling surface.

[0016]

The cleaning sheet according to the present invention has a weakly or non-adhesive first surface area whose dirt wiping surface is in contact with the floor, and a strongly adhesive second surface which is not in contact with the floor. elasticity of the first surface region in the thickness direction while being constituted by a frequency region, the
Since it is higher than that of the two-plane area, it slides well on the floor surface and has a strong trapping force. Since such a cleaning sheet does not stick to the hand, its handling is easy.
