Abstract

PROBLEM TO BE SOLVED: To obtain a sheet for cleaning which has the excellent holding power of dust and slips well on a floor surface by boring a relatively weakly tacky adhesive or non-tacky adhesive sheet with many through-holes and joining the sheet to a relatively the strongly tacky adhesive sheet. SOLUTION: The sheet 1 for cleaning is composed of a base material sheet 2 made of a non-woven fabric, an intermediate sheet 3 which is tacky adhesive on both front and rear surfaces and a front surface sheet 5 of a meshed fabric which is weaker in tacky adhesiveness than the sheet 3 or has no tacky adhesion at all. The front surface sheet 5 has the many through-holes 4 and the tacky adhesive surface on the front surface side of the intermediate sheet 3 faces the through-holes 4. The relatively light dirt, such as dust, is entangled with the non-woven fabric fibers constituting the front surface sheet 5 of the sheet 1 for cleaning constituted in such a manner and if the front surface sheet 5 is has the tacky adhesion, the dirt is captured by the tacky adhesiveness. The relatively heavy dirt, such as sand grains, having the shapes to be hardly entangled with the fibers is admitted into the through-holes 4 of the front surface sheet 5 and is captured by the tacky adhesive surface of the intermediate sheet 3 in the through-holes 4.

Description

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 off dirt and dust on the floor surface.

[0002]

2. Description of the Related Art Heretofore, as this type of sheet, a non-woven fabric raised, a non-woven fabric impregnated with an oil agent, a base sheet coated with an adhesive, etc. are well known.

[0003]

Among the above-mentioned known cleaning sheets, a non-woven fabric brushed has a good sliding property on the floor surface, but has a poor ability to hold relatively heavy dust such as sand grains. Not suitable for wiping off such debris.
Although the non-woven fabric impregnated with the oil agent improves the dust holding power, it may not be said to be sufficient. A cleaning sheet using an adhesive has excellent dust holding power, but does not slide well on the floor due to its adhesiveness. In addition, this cleaning sheet can sometimes be difficult to handle because it can stick to your hands.

[0004] Therefore, an object of the present invention is to obtain a cleaning sheet which is excellent in dust holding power, slides well on a floor surface, and is easy to handle without sticking to a hand.

[0005]

In order to solve the above-mentioned problems, the present invention presupposes a cleaning sheet for wiping dirt and dust on the floor surface. In such a premise,
The present invention is characterized in that at least one of both surfaces of the sheet is a first surface area and a second surface area is located above and separated from the floor surface when the first surface area contacts the floor surface. And the first surface area is relatively weakly tacky or non-tacky, and the second surface area is relatively strongly tacky.

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 includes a base material sheet 2 made of a non-woven fabric, an intermediate sheet 3 having adhesiveness on both upper and lower surfaces, and an adhesiveness weaker than that of the sheet 3, or It is composed of a mesh surface sheet 5 having no tackiness. The topsheet 5 has a large number of through holes 4 and is joined to the base material sheet 2 through the intermediate sheet 3, and the through holes 4 have the adhesive surface on the upper surface side of the intermediate sheet 3 removed. The intermediate sheet 3 and the top sheet 5 shown in the figure are substantially the same in shape and size and overlap each other.
5 has the same length, but is wide and has side edge portions 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-shaped portion 13 and an arm portion 14 pivotally attached to the plate-shaped portion 13. The cleaning sheet 1 is applied to the lower surface of the plate-shaped portion 13, the side edge portion 6 is folded over the upper surface of the plate-shaped portion 13, and is detachably fixed by a clip 8. The appliance 11 has an arm portion 14 and can wipe the floor surface with the surface sheet 5 of the cleaning sheet 1.

Cleaning sheet 1 attached to the instrument 11
Then, relatively light dust such as dust is caught by the non-woven fabric fibers composing the surface sheet 5, and when the surface sheet 5 is tacky, it is trapped by the tackiness. Dust, such as sand grains, which is relatively heavy and which is difficult to be entangled with the fibers, enters the through holes 4 of the surface sheet 5 and is captured by the adhesive surface of the intermediate sheet 3 in the through holes 4. The non-woven fabric used for the surface sheet 5 can be subjected to a raising treatment, can be made bulky by using crimped fibers, or can be impregnated with an oil agent so that dust can be easily captured. Further, the depth of the through holes 4 can be changed depending on the thickness of the surface sheet 5, but the elasticity (cushioning property) in the thickness direction is relatively good, and the through holes may be formed while the cleaning sheet 1 is in use. It is preferable that the adhesive surface of the intermediate sheet 3 is appropriately brought close to the floor surface regardless of the depth of 4. In this cleaning sheet 1, the edge portion 16 of the through hole 4 acts to scrape off the dust attached to the floor, and the scraped dust can be captured by the through hole 4.

The surface sheet 5 of the cleaning sheet 1 used in this way is made to have a weaker adhesiveness than that of the intermediate sheet 3 or has an adhesiveness so that the surface sheet 5 slips well on the floor surface. I haven't.

When the cleaning sheet 1 is attached to the instrument 11, if the base sheet 2 and the surface sheet 5 are held so that the fingers do not touch the intermediate sheet 3, the fingers will not stick to the adhesive surface. The cleaning sheet 1 can be of the same shape and size as the intermediate sheet 3 and the top sheet 5, omitting the side edges 6 if it is not to be attached to the appliance 11.

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

FIG. 4 is a drawing similar to FIG. 3 showing still another embodiment of the present invention. In the cleaning sheet 1, instead of the disc 17, a plurality of strips 18 extending in parallel to each other in one direction covers the intermediate sheet 3 and contacts the floor surface. As the strip 18, a sheet made of non-woven fabric having a required thickness or a fiber such as felt cut into a required width, a filament or split fiber having a relatively large diameter, or a bundle thereof can be used. .

In the present invention, the surface sheet 5 of FIG. 1 used for covering the adhesive surface and rubbing the floor surface, and the disc 17 and strip 18 of FIGS.
On the other hand, it suffices that the sheets 3 are joined by the adhesive force. The intermediate sheet 3 and the topsheet 5 are the base sheet 2
If both sides of the cleaning sheet 1 are dirty,
It may be turned over so that it can be used. For the base sheet 2 and the intermediate sheet 3, other than the illustrated example, an appropriate sheet material can be used.

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

[0016]

EFFECT OF THE INVENTION The cleaning sheet according to the present invention has a dirt-wiping surface having a weak adhesive or non-adhesive surface that contacts the floor surface and a strongly adhesive surface that does not contact the floor surface. Therefore, it slides well on the floor and has a strong gripping force. Since such a cleaning sheet does not stick to the hand, it is easy to handle.
