Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning sheet used, for example, for cleaning (particularly dry wiping) a floor surface.

[0002]

In recent years, a mop-like cleaning tool has been developed and commercialized as a simple floor cleaning tool.

[0003] The mop-type cleaning tool generally comprises a handle and a base connected to the lower end of the handle via a free joint. In particular, the base body has a flat bottom surface (a surface facing the floor surface), and a cleaning sheet is attached to cover the flat surface. Therefore, similarly to the mop, by moving the base body along the floor, dust and the like accumulated on the floor can be collected.

[0004] By the way, as the above-mentioned cleaning sheet to be attached to the periphery of the base body, a relatively thick nonwoven fabric has been conventionally used in consideration of durability and the like. However, the following problems have been pointed out with respect to the cleaning sheet made of such a nonwoven fabric.

Indeed, when a cleaning sheet made of non-woven fabric is used, not only dust but also hair and the like can be reliably collected, so that the cleaning sheet is very useful. However, such a cleaning sheet does not function effectively for relatively large granular dust, such as confectionery waste and bread waste.

That is, once they can be raked together. However, when the base body is subsequently lifted off the floor, the collected relatively large granular debris immediately separates from the cleaning sheet and falls again on the floor just cleaned. This is because relatively large granular trash
This is because it is hard to be entangled with the fibers constituting the nonwoven fabric.

Accordingly, an object of the present invention is to provide a cleaning sheet that can reliably collect even relatively large granular dust.

[0008]

This problem is solved by a cleaning sheet having a sheet body and a plurality of openings formed at predetermined intervals in the sheet body. .

In particular, an object of the present invention is to provide a seat body and a plurality of openings formed at predetermined intervals in the seat body, and around the opening, the sheet body is integral with the seat body, In addition, the above problem is solved by a cleaning sheet, wherein an annular projection is formed to project in the thickness direction of the sheet body.

That is, when the floor is cleaned (dry-wiped) using the cleaning sheet constructed as described above, for example, relatively large granular dust such as confectionery waste and bread waste scattered on the floor surface. Passes through the opening (especially inside the projection) of the sheet body and goes around the back surface (the surface not in contact with the floor) of the sheet body. That is, the dust is finally collected while being placed on the sheet body.

In particular, when the projection is formed on the sheet main body, the dust does not easily return to the front side of the sheet main body. For this reason, a defect like the conventional product, that is, once the dust is collected, if the cleaning sheet is separated from the floor, the collected dust falls again on the floor just cleaned. There is no problem of getting lost. In other words, by using the cleaning sheet of the present invention, it is possible to reliably collect relatively large dust particles that are not easily entangled with the fibers.

In the cleaning sheet of the present invention,
In order to further enhance the dust collecting effect, it is preferable that the protrusion has a C-shaped cross section whose inner diameter becomes smaller toward the tip. That is, if the protrusions have such a shape, it is almost impossible for the dust that has once passed through the protrusions to return, so that the dust collecting effect is further improved.

Furthermore, it is preferable that the cleaning sheet of the present invention is used in a state of being attached to a base body having a flat surface so as to cover the flat surface. When the cleaning sheet of the present invention has a structure having projections, it is preferable to attach the cleaning sheet to the base body such that the surface on which the projections are present faces the flat surface of the base body. .

However, a cleaning sheet may be attached to the base body so that the surface having no projections faces the flat surface of the base body (in this case, the projections also exert a dust scraping function). In other words, the cleaning sheet of the present invention can use both surfaces of the cleaning sheet, even if it has projections. To be careful, when the above-mentioned base body is used in combination, the relatively large granular dust collected is
It is stored in the space between the base body and the cleaning sheet (sheet body).

The sheet body in the cleaning sheet of the present invention can be made of, for example, a nonwoven fabric, a paper material, or a plastic film. However, in order to reliably collect fine dust and hair, it is desirable that the sheet body is made of a non-woven fabric in particular.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cleaning sheet described below as an embodiment of the present invention includes a sheet body and a plurality of openings formed at predetermined intervals in the sheet body. is there. In particular, in the present embodiment, an annular projection that is integral with the sheet body and protrudes in the thickness direction of the sheet body is formed around the opening. The projection has a C-shaped cross section whose inner diameter decreases toward the tip. Furthermore, the cleaning sheet is used in a state where it is attached to a base body having a flat surface so as to cover the flat surface.

Next, an embodiment of the present invention will be described more specifically with reference to FIGS. 1 is a perspective view showing a state in which the cleaning sheet according to the present embodiment is attached to the base body of the cleaning tool, FIG. 2 is an enlarged sectional view of the cleaning sheet, and FIG. FIG. 4 is a schematic view showing the function of the cleaning sheet according to the present embodiment.

As described above, the cleaning sheet according to the present embodiment (hereinafter referred to as the main cleaning sheet) is attached to the base body constituting the mop-type cleaning tool to clean the floor surface (for example, It is used for dry wiping.

More specifically, as can be seen from FIG.
The base body B is a rectangular parallelepiped having a particularly flat bottom surface.
Is attached so as to cover the bottom surface (flat surface), side surfaces and part of the top surface. Incidentally, the base body B is made of rubber or a relatively hard sponge-like material.

In FIG. 1, the main cleaning sheet A is shown.
Are not particularly shown. However, in practice, the main cleaning sheet A is fixed to the base body B by detachably engaging a part of the cleaning sheet A with the top surface of the base body B. Although not shown in FIG. 1, a handle having a length of about 1 m is connected to the base body B via a universal joint (universal joint).

Therefore, when cleaning the floor, the handle is operated to move the base body B along the floor. However, as for the main body of such a cleaning tool, an existing one can be used as it is, and its structure is already known. Therefore, further detailed description is omitted.

As shown in FIG. 2, the main part of the cleaning sheet A is a sheet main body 1 made of a nonwoven fabric or the like. The sheet body 1 has a plurality of openings 2 at predetermined intervals. Here, the opening 2 is formed in a circular shape.
The distance between them is almost equal to the diameter (of course, it can be larger or smaller).

Further, an annular projection 3 is formed around the opening 2. The projection 3 is integral with the seat body 1 and protrudes in the thickness direction of the seat body 1. In particular, as shown in FIG. 3, the protrusion 3 has a C-shaped cross section in which the inner diameter becomes smaller toward the tip end contacting the bottom surface of the base body B. Incidentally, in the present embodiment, the projections 3 having such a structure are formed simultaneously with the formation of the openings 2 by a punching press process for forming the openings 2.

The projections 3 do not need to be formed on the side corresponding to the side surface or the top surface of the base body B. Further, the main cleaning sheet A does not necessarily have to be attached to the base body B in such a direction that the projections 3 are in contact with the bottom surface of the base body B. That is, the main cleaning sheet A may be attached to the base body B in a direction opposite to the above-described state so that the projections 3 face the surface to be cleaned (floor surface).

The main cleaning sheet A constructed as described above.
Functions as follows when used with the base body B (see FIG. 4).

In other words, when cleaning (dry wiping) the floor surface using the main cleaning sheet A, the main cleaning sheet A moves in parallel with the base body B along the floor surface. At this time, if relatively large granular dust D such as confectionery waste or bread waste is present on the floor surface, the dust D is removed from the opening 2 of the sheet body 1.
And further passes through the inside of the projection 3 and wraps around the back surface (the surface on the base body B side not in contact with the floor surface) of the sheet body 1. That is, since the dust D is finally collected while being placed on the sheet main body 1, it does not return to the floor again.

For this reason, even if dust is once collected, like a conventional product (especially a simple nonwoven fabric), if the cleaning sheet is lifted off the floor together with the base body, the dust is immediately separated from the cleaning sheet, and the dust is removed. There is no problem such as falling again on the floor just finished. In other words,
By using the cleaning sheet A, it is possible to surely collect relatively large granular dust such as confectionery waste and bread waste, which are not easily entangled with the fiber.

In addition, despite having such excellent functions, the present cleaning sheet A has an extremely simple structure, so that the manufacturing operation is easy and it can be provided at a low cost. The shapes of the openings 2 and the projections 3 formed in the seat body 1 and the positions and intervals thereof are not limited to the above-described embodiment, and can be implemented with appropriate changes.

Here, the case where the main cleaning sheet A is used as it is has been described as an example, but the main cleaning sheet A can be used in various forms other than this. .

For example, two main cleaning sheets A are stacked (or one sheet is folded in half) so that the surfaces on which the projections 3 do not exist or the surfaces on which the projections 3 exist face each other. Can be used. That is, it may be commercialized in this form. Further, it is also possible to use a third sheet having no openings or protrusions between the two main cleaning sheets A thus laminated. That is, it may be commercialized in this form.
