[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sponge cleaning tool used for car washing and other cleaning.

[0002]

2. Description of the Related Art A conventional sponge cleaning tool used for washing a car with water or soapy water, such as a sponge having a size and shape that can be held by hand, and a sponge for holding by hand. There was a thing with a pattern. Such a sponge cleaning tool helps the sponge to hold water and soapy water with a large number of air bubbles, and has the effect of removing dirt attached to the car body etc. because the surface of the sponge is rough. It has the advantage of being superior. In addition, since the sponge has flexibility, the sponge has an advantage that the sponge easily follows the curved surface when cleaning the convex curved surface or the concave curved surface.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has the advantages and advantages of conventional sponge cleaning tools, namely, the ability to retain water and soapy water and to remove dirt. It is an object of the present invention to provide a cleaning tool made of sponge capable of exhibiting the effect, the property of easily following a curved surface, and the like more remarkably.

[0004]

A sponge cleaning tool according to the present invention has a sponge base layer and a sponge surface layer laminated on the sponge base layer, wherein the sponge surface layer reaches the sponge base layer. Is divided into a number of blocks.

According to this sponge cleaning tool, the sponge surface layer is divided into a large number of blocks by the cuts, so that the individual blocks can easily move individually. for that reason,
When pressed against a convex or concave curved surface, the surface of the sponge becomes easier to follow the curved surface as a whole, and it is easier to push the block of the sponge surface into a narrow gap, which is a curved surface compared to a conventional sponge cleaning tool. This helps to increase the contact area with the vehicle and makes it possible to perform car washing and the like more efficiently than conventional ones. In addition, the cuts serve to hold water or soapy water, and the ability to hold water or soapy water, the property of improving foaming, and the effect of removing dirt are remarkably exhibited as compared with conventional ones. In addition, the sponge base layer helps to prevent the sponge surface layer, which is divided into a number of blocks by the cuts, from being deformed.

[0006] The sponge base layer can have more flexible properties than the sponge surface layer, so that a large number of blocks formed on the sponge surface layer have a certain stiffness. It is easy to have and it is easy for the blocks to swing around the joint with the sponge base layer, that is, the root of the block as a fulcrum, so that the creeping property to the curved surface (the property along the curved surface) Is less likely to be inhibited, and a good cleaning action is easily exhibited.

The above-mentioned cuts can be formed so as to have a certain regular pattern pattern or irregular pattern pattern. It is possible to form a symmetrical pattern such as line symmetry and point symmetry before and after. If the cut is formed in a symmetrical pattern,
It is possible to make the pattern pattern of the cut have a radial direction or to make the pattern pattern a lattice pattern. In addition, it is desirable that the block located on the outermost side of the sponge base layer be larger than the block located on the inner side of the sponge base layer. By doing so, the outermost block that receives the greatest load when used for cleaning is larger than the inner block, so the bonding strength between the outermost block and the sponge base layer is set to the inner block. The sponge cleaning tool has an advantage that the durability of the sponge cleaning tool is improved because it is easy to secure the bonding strength larger than the bonding strength between the sponge base layer and the sponge base layer.

In the sponge cleaning tool according to the present invention, a backup layer made of a sponge having the same degree of flexibility as the sponge surface layer is laminated on the opposite side of the sponge surface layer with the sponge base layer interposed therebetween. It is also possible to adopt a configuration in which a flat attachment portion provided at the tip of the handle is fixed in an overlapping manner. With this configuration, the backup layer that is harder (less flexible) than the sponge base layer and the flat attachment portion of the handle fixed in an overlapping manner on the backup layer back up the flexible sponge base layer from the back. Therefore, it is easy to press a large number of blocks against a convex curved surface or a concave curved surface with a large force without impeding the above-mentioned property that each block is easily movable individually.
That helps to increase the efficiency of car washing.

1 is a front view of a sponge cleaning tool according to the present invention, FIG. 2 is a partially cutaway side view of the sponge cleaning tool, and FIG. 3 is a plan view of the sponge cleaning tool. . This cleaning tool made of sponge includes a head portion 1 in which sponges are laminated in three layers and a handle 2, and the handle portion 2 can be held by hand, and the head portion 1 can clean a washing location such as a vehicle body. It has become.

[0010] The three sponge layers of the head 1 are adhered to each other with an adhesive. The three sponge layers include a sponge base layer 3 as an intermediate layer, and a sponge surface layer 4 and a backup layer 5 laminated on both sides of the sponge base layer 3. The sponge surface layer 4 has a relatively large number of closed cells and is a relatively hard layer.
Therefore, the sponge surface layer 4 has an excellent property of scraping off dirt. Sponge surface layer 4 for backup layer 5
The same sponge is used. Sponge base layer 3
Is more flexible than the sponge surface layer 4, and the size of the bubbles is smaller than that of the sponge surface layer 4. Handle 2
The flat mounting portion 21 provided at the front end portion is attached to the backup layer 5 in an overlapping manner using an adhesive. The mounting portion 21 is overlapped only in a certain range in the center of the backup layer 5, and the mounting portion 21
, The surface of the backup layer 5 is exposed over a certain width.

The sponge base layer 3 is provided on the sponge surface layer 4.
Are formed, and the sponge surface 4 is divided into a number of blocks 7 by the cuts 6.
Is divided into

According to the cleaning tool made of sponge configured as described above, the sponge surface layer 4 is divided into a large number of blocks 7 by the cuts 6, so that the individual blocks 7 can easily move individually. Therefore, when pressed against the convex curved surface P1 shown in FIG. 7 or the concave curved surface P2 shown in FIG. 8, the sponge surface layer 4 (see FIG. 2 and the like) as a whole has those curved surfaces P1,
It becomes easier to follow P2, and the cleaning of a portion having a narrow gap or a protrusion can be easily performed using the block 7 of the sponge surface layer 4. From these facts, it is not only possible to efficiently perform car washing by increasing the contact area with the curved surface than the conventional sponge cleaning tool, but also it is difficult to perform reliable cleaning with the conventional sponge cleaning tool. It is possible to reliably clean even a narrow portion such as a concave curved surface formed in a handle portion of an automobile door. Further, the ability to retain water or soapy water is exerted not only by the air bubbles of the individual blocks 7 of the sponge surface layer 4, the sponge base layer 3, the backup layer 5, etc., but also by the cuts 6, so that the ability is increased. That also improves foaming during washing.

In this sponge cleaning tool, a large number of blocks 7 formed on the sponge surface layer 4 have a certain stiffness and flexibility, and such a stiff block 7 has a flexible sponge base layer 3. , The blocks 7 oscillate with their roots as fulcrums during actual car washing.
For this reason, a good cleaning action is exhibited without hindering the creeping property on the curved surface. This cleaning effect is more remarkably exhibited because the sponge base layer 3 is supported by the harder backup layer 5 and the flat mounting portion 21 of the handle 2 is fixed to the backup layer 5 in an overlapping manner. Is done.

The cut 6 can be formed so as to have a fixed regular pattern pattern or an irregular pattern pattern.

FIGS. 1, 4 to 6 show a cleaning tool made of sponge in which the cuts 6 have a regular pattern. Of these, the pattern patterns of FIGS. 1 and 4 are symmetric pattern patterns.

That is, in the cleaning tool made of sponge of FIG. 1, the pattern of the cut 6 is line-symmetric or point-symmetric in the left, right, front and back. Specifically, the pattern pattern is formed by combining cuts that cross the sponge surface layer 4 left and right, a plurality of cuts in the radial direction, and a plurality of cuts having different sizes and forming a plurality of parallel closed curves. I have. With this configuration, the size of each block 7 formed by the cut 6 increases as the distance from the center point increases. Therefore, of the many blocks 7, the block 7a located on the outermost side of the sponge base layer 3 is the other block 7 located on the inner side.
Greater than. With such a structure, it is easy to ensure that the bonding strength between the outermost block 7a and the sponge base layer 3 is larger than the bonding strength between the inner block 7 and the sponge base layer 3. Since the 7a itself is not easily torn, the durability of the sponge cleaning tool is improved.

The pattern of the cut 6 of the cleaning tool made of sponge of FIG. 4 is a lattice pattern, and the size of each block 7 is the same. The pattern pattern of the cut 6 of the cleaning tool made of sponge in FIG. 5 is obtained by combining a plurality of cuts of concentric circles, two cuts extending in front and rear and left and right, and two arc-shaped cuts formed by being distributed right and left. It is formed. The pattern pattern of the cut of the cleaning tool made of sponge of FIG. 6 is formed by combining a plurality of parallel cuts extending in the front-rear direction and a plurality of parallel cuts in the waveform extending in the left-right direction.

In the above-described embodiment, the sponge cleaning tool having the handle 2 has been described. However, it is also possible to form the sponge cleaning tool only with a portion corresponding to the head portion 1 without the handle 2. Such a sponge cleaning tool is used directly by hand. Further, the shapes of the handle 2 and the head 1 are not limited to those shown in the drawings. Further, in the head section 1, the backup layer 5 can be omitted.

[0019]

According to the present invention, the advantages and advantages of the conventional sponge cleaning tool are further enhanced, and the water and soap water retention ability, the property of improving foaming, the effect of removing dirt, and the like are excellent. It is possible to provide a cleaning tool made of sponge.
