Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a disposable wiping material for wiping off dirt such as a floor surface and a wall surface.
[0002]
[Prior art]
A mop-shaped cleaning tool disclosed in Japanese Patent Application Laid-Open No. 4-114620 has a long handle and a sheet mounting substrate located at the end of the long handle, and a disposable dirt wiping sheet made of a nonwoven fabric or the like on the bottom surface of the substrate Cover the floor with a long handle and wipe the floor with the sheet. The planar shape of the substrate is rectangular, and the bottom surface of the substrate is formed with a medium height in the direction along the short side. When using a cleaning tool, rubbing the floor surface with the middle and high parts of the bottom can scrape off the floor. Further, the side edge portion of the bottom surface along the long side of the substrate can be separated from the floor surface, and relatively large dust can be collected between the bottom surface and the floor surface when separated. . When the sheet mounting substrate is thus medium and high, it is possible to collect large dust that cannot be collected by a cleaning tool in which the entire bottom surface of the substrate is in close contact with the floor surface.
[0003]
[Problems to be solved by the invention]
If the bottom surface of the substrate for attaching the sheet of the cleaning tool is flat, the known effect of collecting the cleaning tool cannot be obtained. However, cleaning tools having a flat bottom surface are widely used in general.
[0004]
Then, this invention makes it the subject to provide the disposable dirt wiping material which makes it possible to use the bottom face in a medium-high state when the bottom face of the sheet mounting substrate is attached to a flat cleaning tool.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the present invention, a disposable dirt wiping material formed from a thermoplastic synthetic fiber nonwoven fabric , having a first surface and a second surface parallel to each other, and having a substantially rectangular planar shape. The first surface is substantially flat and the second surface is relatively low in a side edge region of a required width along each of a set of parallel sides, and the side are relatively high formed in an intermediate region interposed between the edge zone, the cross-sectional shape of the intermediate region in a direction perpendicular to said parallel pair of sides Ri der either trapezoidal or rectangular, the side edges The region is shaped by heating and pressurizing .

DETAILED DESCRIPTION OF THE INVENTION
The details of the disposable dirt wiping material according to the present invention will be described below with reference to the accompanying drawings.
[0007]
FIG. 1 is a perspective view of a cleaning tool 2 to which a disposable dirt wiping material 1 is attached. The cleaning tool 2 has a substrate 3 and a handle 4, and the wiping material 1 that is in contact with the bottom surface 3 </ b> B of the substrate 3 has side edge regions 16 and 17 folded on the top surface 3 </ b> A of the substrate 3, It is fixed. The cleaning tool 2 in such a state has a handle 4 and is used by gently wiping the floor surface with the wiping material 1.
[0008]
The wiping material 1 shown in a perspective view in FIG. 2 is obtained by extending that in FIG. 1 upside down. The wiping material 1 has two sets of sides 11, 12 and 13, 14 that are parallel to each other, the planar shape is a rectangle or a rectangular shape that is a square, and a bottom surface 21 that contacts the bottom surface 3 </ b> B of the substrate 3. And a top surface 22 located on the floor surface side. In the illustrated example, a rectangular shape whose sides 11 and 12 are longer than the sides 13 and 14 is shown, and the side edge regions 16 and 17 having widths W1 and W2 along the sides 11 and 12 are relatively thin. The central area 18 having a width W3 extending between the left and right end edges 13 and 14 is interposed between the side edge areas 16 and 17, and the thickness of the central area 18 is relatively increased. is there. The entire bottom surface 21 of the wiping material 1 is formed flat. Therefore, the top surface 22 is in a state in which the peripheral regions 16 and 17 are relatively low and the central region 18 is relatively high.
[0009]
In the state where the wiping material 1 is attached to the substrate 3 as shown in FIG. 1, the side edge regions 16, 17 are portions 16 A, 17 A where the side edge regions 16, 17 are folded over the top surface 3 A of the substrate 3, and the vicinity of the side edge 24 of the substrate 3. And have portions 16B and 17B in contact with the bottom surface 3B. Of each part, the parts 16 </ b> A and 17 </ b> A are formed so as to reach the clip 8. Each of the portions 16B and 17B is preferably formed so that it can occupy 1/10 to 3/10 of the width W of the substrate 3, and the width W3 of the central region 18 occupies the remaining width. If the cleaning tool 2 is for household use, the width W3 of the central region 18 is preferably 80 to 40 mm, the height H from the side edge regions 16 and 17 is 3 to 20 mm, and 5 to 10 mm. It is more preferable that
[0010]
The wiping material 1 may be formed by partially heating and pressing a thermoplastic synthetic fiber nonwoven fabric having a thickness of, for example, about 3 to 25 mm to form the side edge regions 16 and 17. The side edge regions 16 and 17 obtained in this way are denser than the central region 18, and the fibers are less likely to loosen, preventing the wiping material 1 from being out of shape and allowing the clip 8 to be securely fixed. . If the nonwoven fabric in which the composite fiber is crimped is used, the central region 18 becomes a bulky and elastic portion. The side edge regions 16 and 17 and the central region 18 can be impregnated with a required oil agent to facilitate collection of dust.
[0011]
When the floor surface is wiped with the cleaning tool 2 shown in FIG. 1 using the wiping material 1, the top surface 22 of the central region 18 is brought into contact with the floor surface, and fine dust that can enter between the top surface 22 and the floor surface. Are collected in the central area 18. Relatively large dust that cannot penetrate under the central area 18 gathers under the parts 16B and 17B of the wiping material 1, so that it adheres to the parts 16B and 17B and the side surface 18A of the central area 18, The parts 16B and 17B and the side surface 18A can be gathered at one place on the surrounding floor so as not to be dissipated. When the central area 18 has a suitable hardness, the floor surface can be scraped off in the area 18. In order to enhance the scraping effect, the end face shape of the central region 18 may be rectangular or trapezoidal.
[0012]
In addition to the illustrated example, the wiping material 1 can be appropriately bonded, welded, stitched, or the like by bonding a fiber assembly such as a nonwoven fabric or felt to be the central region 18 to one side of a sheet material having required characteristics such as a plastic film or a nonwoven fabric. You may join by a means.
[0013]
【The invention's effect】
Since the wiping material according to the present invention has a flat bottom surface, both side edge regions parallel to each other are relatively thin, and an intermediate region interposed between both side edge regions is relatively thick. A cleaning tool with a flat bottom surface of the substrate for attaching it can be changed to a medium and high bottom surface.
