Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool for wiping and removing dirt adhered to surfaces of furniture such as desks, tableware and automobiles, a method of manufacturing the same, and a method of using the same.

[0002]

2. Description of the Related Art Conventionally, when a surface of furniture such as a desk or a chair, tableware or a car becomes dirty, a cleaning cloth, a nylon scourer, a urethane sponge, or the like is mainly used as a cleaning tool to remove the stain. With these cleaning tools, dirt attached to the surface of furniture or the like is wiped off by rubbing the surface.

For example, in the case of a rag, the dirt is wiped off in a dry state or immersed in water or water mixed with a detergent, and rubbed with the surface of furniture or the like. When a rag is used, there is a drawback that even if a detergent is used, it is less effective against oil stains and stubborn stains. Similarly, with respect to nylon scourers and urethane sponges, dirt is wiped off by rubbing surfaces of furniture and tableware with water or water mixed with a detergent. In this case, for oil stains and stubborn stains, rubbing the surface strongly makes it easier to remove dirt than a rag, but there is a drawback that the surface such as a painted surface is easily scratched and a wipe mark remains. .

At present, these drawbacks are eliminated, that is, there is a sufficient effect on oil stains and stubborn stains.
Some cleaning tools using a melamine resin foam are commercially available as cleaning tools that hardly leave any wiping marks.

[0005]

However, the above-mentioned cleaning tool using a melamine resin foam has a problem that it is quickly worn due to its fragile properties and inferior in durability due to its properties.

The present invention, in consideration of such problems of the conventional cleaning tool, has a sufficient stain removing effect against oil stains and stubborn stains, has improved wear durability, and has a lower cost. It is an object to provide a cleaning tool that can be reduced, a manufacturing method thereof, or a usage method thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings showing the embodiments. (First Embodiment) FIG. 1 is a perspective view showing a cleaning tool according to a first embodiment of the present invention. That is, the cleaning tool 10 of the present embodiment is formed by heating and pressing the melamine resin foam to compress the melamine resin foam. It is configured. In the present embodiment, a large number of protrusions 12a are formed on the plane 12b.

Next, a method for manufacturing the cleaning tool of the above embodiment will be described with reference to the drawings.

As is known, a melamine resin foam is a foamed plastic having an open cell structure produced from a melamine / formaldehyde resin obtained by an addition condensation reaction of melamine and formaldehyde, and a foaming agent component. Typical mechanical properties of this melamine resin foam include a density of 10.5 to 11.5 kg / m3, a tensile strength of 0.1 to 0.15 N / mm2, and an elongation at break of 10
~ 20%. As for the mechanical properties of the melamine resin foam described in JP-A-11-128137, the density is 5 to 50 Kg / m3 and the tensile strength is 0.
6 to 1.6 kg / cm2, elongation at break 8 to 20%,
The cell number is described as 80 to 300 cells / 25 mm.

First, the melamine resin foam which has just been foamed is heated and pressed to be compressed. As for the temperature at the time of heating and the pressure at the time of pressurization, the temperature is 200 to 230 ° C and the pressure is 90 to
It is effective in the range of 100 kg / cm2. For example, if the heating temperature is 200 ° C. and the pressure at the time of pressurization is 90 kg / cm 2, the mechanical properties are as follows.
0.0Kg / m3, tensile strength 0.4 ~ 0.75N
/ Mm2 (according to JIS 6400), elongation at break is 1
0-20% (according to JIS6400), cell number is horizontal 8
0-300 pieces / 25mm, vertical 280-1500 pieces / 2
5 mm.

When the melamine resin foam is compressed in this way, the density of the cells increases, the cells (bubbles) become smaller and the texture becomes finer, so that the durability increases and the object to be rubbed is damaged. It becomes difficult. Here, by controlling the temperature at the time of heating and the pressure at the time of pressurization within the above-described ranges, the melamine resin foam can be manufactured into a cleaning tool main body having a desired strength. That is, it is possible to suppress the brittle collapse.

Next, as shown in FIG. 1, a continuous diamond-shaped concavo-convex pattern portion 12 as shown in FIG. 1 is formed by embossing on the surface of the cleaning tool body produced by compressing the melamine resin foam. For example, it may be formed by continuously pressing with a metal roll having a surface engraved with an uneven pattern. Alternatively, a metal plate having a hole having an uneven pattern may be pressed from above.

Thus, the cleaning tool 10 composed of the cleaning tool body 11 having the uneven pattern portion 12 formed on the surface is manufactured.
As described above, if the surface has the uneven pattern portion 12, when rubbing the surface to remove dirt such as furniture, the convex portion mainly removes dirt, which is compared with the case of rubbing on a flat surface. And the dirt removal effect and durability are further increased.

As a modification of the present embodiment, a melamine resin foam which is subjected to only compression by heating and pressurizing and is free from embossing and has no concavo-convex pattern can be considered.
Even in such a case, the effect is reduced as compared with the case where there is a concavo-convex pattern, but the dirt removing effect and the durability are improved as compared with those using a conventional melamine resin foam.

Further, the amount of raw materials for obtaining the same effect as in the prior art can be reduced. For example, in the case of a conventional melamine resin foam, when the amount of dirt that can be removed using a 4 cm-thick one is taken as one reference, in order to obtain the same effect, in the present invention, a thickness of 1.5 cm is used. Can be realized by pressing and heating and compressing the melamine resin foam to a thickness of 3 mm. Therefore, when it is considered that the same effect is obtained in the case where the time until practical use is the same when used under exactly the same conditions, the amount of the raw material is 1.5 / 1.5 That is, four or less is sufficient. The reason for this is that, when embossing is performed to form a concavo-convex pattern as in the present embodiment, the effect is further improved as compared with a flat surface.

FIG. 2 is a perspective view showing a cleaning tool according to an applied example of the present embodiment. That is, the cleaning tool 20 of this application example is a cleaning tool 10 composed of the cleaning tool body 11 described with reference to FIG. Since the surface can be used on both sides, in this case, either one may be determined for the sake of convenience, and one of them is determined as such).

The grip portion 21 is for reinforcing and protecting the melamine resin foam 11 so that the wiping operation can be performed more reliably and easily. The grip portion 21 is made of foamed plastic such as foamed polyurethane, foamed polyethylene, foamed polystyrene, or the like. An appropriate member such as a plastic such as vinyl, acrylic, polyurethane, polyethylene, polystyrene, and nylon may be bonded to one side with an adhesive or the like. As described above, by attaching the reinforcing member to one surface, handling becomes practically easy, and it is possible to suppress the collapse of the mold when a force is applied.

The grip 21 is not limited to the one shown in FIG. 2, but may be one that covers a part or all of the side surface of the cleaning tool main body 11 or one that has a handle. (Second Embodiment) FIG. 3 is a perspective view showing a cleaning tool according to a second embodiment of the present invention. That is, the cleaning tool 30 of the present embodiment is provided on one surface (the surface opposite to the surface for removing dirt) of the cleaning tool 10 composed of the cleaning tool main body 11 described in the first embodiment. The non-woven fabric 31 is formed by hot-melt bonding 32 using a heat-fusible binder.
The non-woven fabric is manufactured by using fibers such as polyester, acrylic, polypropylene, rayon, acetate, vinylon, and nylon as materials, and tangling the fibers with each other using a mechanical method by a needle punch method or a chemical method. By bonding such a nonwoven fabric, the strength is further increased and the durability is improved. Furthermore, by using a nonwoven fabric, antibacterial fibers can be mixed to impart antibacterial properties, or tourmaline, which is a type of abrasive, or another abrasive can be mixed to further improve the stain removal effect. This is because the abrasive such as tourmaline mixed into the nonwoven fabric 31 spills down to the dirt removing surface side through the air bubbles of the cleaning tool body during use. In addition, tourmaline has a water purification effect in water.

Here, the non-woven fabric 31 may be attached to the cleaning tool main body 11 by a method other than the above-described method using an adhesive such as a synthetic resin, a synthetic rubber, or a thermosetting resin. Alternatively, a method in which the nonwoven fabric itself is heat-fused using a material having heat-fusibility may be used.

FIG. 4 shows an application example in which the cleaning tool 30 of this embodiment is processed and used. As shown in FIG. 4, the cleaning tool main body 11 and the opposite end portions 33 of the nonwoven fabric 31 are rolled.
Are bonded using an adhesive, a heat-fusible nonwoven fabric, or hot-melt bonding using a heat-fusible binder to form a cylindrical shape. It is also conceivable that one end of this cylindrical shape is manufactured into a bag shape by using an adhesive or by heat fusion. With this configuration, a handle such as a hard plastic support rod or the like can be attached, or the hand can be used, so that it is easy to hold when applying force, and a convenient cleaning tool can be configured.

FIG. 5 shows a modification of this embodiment, in which two cleaning tool bodies 11 are bonded together with a nonwoven fabric 31 interposed therebetween. Thereby, it is possible to realize a cleaning tool that can improve strength and can use both surfaces. (Third Embodiment) FIG. 6 is a perspective view showing a cleaning tool according to a third embodiment of the present invention. That is, the cleaning tool 40 of the present embodiment is, for example, provided on one side of the core member 42 made of the cleaning tool body described in the first embodiment, which is obtained by compressing and embossing a conventional melamine resin foam. It has a configuration in which a mesh member 41 having a mesh shape is attached. The surface of the mesh member 41 is cleaned.

The mesh member 41 is formed on a sheet member 71 such as synthetic paper, pulp, cloth or non-woven cloth having a suitable strength (for example, tensile strength of 150 to 230 N / mm 2), as shown in FIG. As shown in the figure, a cut 72 is formed in a zigzag shape, and this is pulled to both sides in the direction of the arrow to produce a metal lath as shown in FIG. 7B. That is, when the cut 72 is inserted as shown in FIG. 7 (a) and it is pulled from both sides, the gap 41a becomes wider as it is pulled, and the ridge 41b and the connecting portion 41c together with the pull before pulling Everything is inclined obliquely in the same direction with respect to the first surface, and one side of the ridge line portion 41b and the connecting portion 41c rises from the plane, as if a thin honeycomb shape was squashed diagonally. A three-dimensional shape is formed. This shape is basically the same as metal lath used in construction and the shape and shape are the same.

Here, the method of forming the cut 72 can be made, for example, by providing a cutter blade in a staggered manner around the roller and rotating the roller while feeding a cloth or nonwoven fabric. Alternatively, a punching method in which a cutter blade is pressed from above can be used as another method. Also, the way of making the cut 72 is shown in FIG.
In addition to the pattern shown in FIG. 8, for example, as shown in FIG. 8A, a pattern in which cuts 72 having different longitudinal directions by 90 degrees may be arranged alternately in one direction (vertical direction). As shown in FIG. 8 (b), the pattern of FIG. 8 (a) may be a pattern in which cuts 72 whose longitudinal direction is different by 90 degrees in the horizontal direction are arranged alternately. Alternatively, as shown in FIG. 8 (c), a pattern in which notches 72 such as not a straight line but a hook shape are alternately shifted in the opposite direction may be used. As described above, if the direction of the cut 72 is changed, the edge portion acts in either direction of moving the cleaning tool when removing dirt, so that the dirt removing effect is improved.

In this embodiment, an example in which the cleaning tool body described in the first embodiment is used as the core member 42 has been described. In addition, a sufficient removal effect and durability can be obtained.
Alternatively, as the core member, a normal melamine resin foam can be used, and in addition, other foamed plastics such as foamed polyurethane, expanded polystyrene, and expanded polyethylene may be used. A sufficient removal effect and durability can be obtained by a synergistic effect with 41. For example, a soft polyester material can be used as the core member 42 and a hard polyester nonwoven fabric can be used as the mesh member 41 in combination.

When the gap 41a is formed in the cutout 72 as shown in FIG. 7B, the mesh member 41 can be made plastic so that it does not return to its original state. You may be able to return to the original state by holding it and stopping pulling from both sides and releasing it. And the mesh member 41
The mesh cut 72 can be made plastic or elastic depending on how the core member 42 is combined with the mesh.

With this configuration, the second
In addition to the effects of the embodiment, since the mesh-like member 41 has the same shape as the metal lath, the ridge portion is inclined with respect to the surface, and the dirt removing effect is further improved at the edge portion.

As described above, in the present embodiment, the mesh member 41 formed by making a cut 72 in a cloth or nonwoven fabric is bonded to the core member 42.
Alternatively, after the cloth or nonwoven fabric is bonded to the core member 42, the cut 72 may be formed in the cloth or nonwoven fabric and the core member 42 at the same time. In this case, the cut 72 may be formed at a certain depth from the cloth or the nonwoven fabric side because the cut 72 may be formed in the cloth or the nonwoven fabric, or may be a depth penetrating the core member 42. In this case, since the edge of the mesh member 41 is bonded to the edge of the cut 72 of the core member 42, the cut 72
The edge portion becomes stronger than when the mesh-like member 41 filled with is attached to the core member 42 having no cut 72, and the stain removal effect and durability are improved.

In order to reinforce the entire cleaning tool 40,
A structure in which a cloth or a nonwoven fabric is stuck on the back surface (the surface on which the mesh-shaped member 41 is not stuck) or the side surface of the core member 42 may be adopted. This makes it easier to put effort into use and improves operability.

Furthermore, if tourmaline, which is a kind of abrasive, or another abrasive is mixed between the core member 42 and the mesh member 41, the tourmaline or the abrasive gradually decreases from between the meshes when used. It peels off, and the stain removal effect is further improved as compared with the above case. In addition, tourmaline has a water purification effect in water.

In the above-described embodiment, the mesh member is formed in a mesh shape with a gap opened by being pulled in a direction perpendicular to the length direction of the cut 72, but is not limited to this. It is good also as a state. In that case, in the case of melamine resin foams, when water is included, the foam expands to open a gap, and also in other materials, the cut 72 is slightly opened during use operation, and the edge effect at the corner of the cut 72 is similarly increased. Can be expected.

In the above embodiment, the mesh member 41 is attached to one surface of the rectangular parallelepiped core member 42. However, the present invention is not limited to this, and the mesh member 41 is attached to two or more surfaces of the core member 42. 41 may be attached, or the entire surface of the core member 42 may be wrapped.

In the above embodiment, the mesh member is combined with the core member to obtain the effect of the mesh shape. However, the present invention is not limited to this, and the cleaning tool described in the first embodiment is not limited to this. The main body, a compressed melamine resin foam that has not been embossed, a normal melamine resin foam, or other foamed plastic such as foamed polyurethane, foamed polystyrene, foamed polyethylene, etc., as a single material Alternatively, a configuration in which a cut 72 is formed in the gap 72 or a configuration in which the mesh 72 is pulled in a direction perpendicular to the length direction of the cut 72 to form a mesh with a gap may be used. Also in this case, as in the case of the present embodiment, a sufficient dirt removing effect can be obtained by the edge portion of the mesh shape.

In the above-described embodiment, the core member or the cleaning tool main body has a rectangular parallelepiped shape.
For example, the shape may be a ball shape or an elliptical shape, and the shape is not limited thereto.

In the above embodiment, the mesh member is provided only on one surface, but may be provided on the other surface. In that case, both surfaces can be used for dirt removal. (Fourth Embodiment) FIG. 9 is a perspective view showing an example of a cleaning tool according to a fourth embodiment of the present invention. That is, the cleaning tool 50 of the present embodiment is formed by spirally winding the structure of the third embodiment described above so that the mesh-like member 51 comes out on the surface, and adhered by an adhesive or heat fusion. Things. The mesh member 51 sandwiched between the core members 52 in the overlapped portion is single. By being wound in this manner, the ridge 41b of the mesh-like member 51 exposed on the surface rises spontaneously, thereby further improving the dirt removal effect as described above, and furthermore, the core member 52.
Because of the three-dimensional structure, the mesh-like member 51 sandwiched between the members can exhibit the action of a spring and have elasticity.

FIG. 10 is a perspective view showing another example of the present embodiment. That is, the cleaning tool 60 of the present embodiment has the configuration of the third embodiment described above,
The mesh member 61 is folded in a 99-fold form so as to be exposed on the surface, and bonded by an adhesive or heat fusion. The mesh part 61 sandwiched between the core members 62 of the overlapped part has more elasticity because the mesh is double overlapped.

At the opposite overlapping portion 64, the mesh member 6
1 does not exist. As a result, the mesh-like member 61 exposed on the surface improves the dirt removal effect in the same manner as described above, and the mesh-like member 61 sandwiched between the core members 62 acts as a spring because of its three-dimensional structure. It can be presented to make it elastic. Further, in this example, since the bent portion 65 has a wavy shape, an improvement in the stain removal effect can be expected by using the bent portion.

As described above, in the present embodiment, the core member 62
Since the mesh-like member 61 having a three-dimensional structure is sandwiched between the insides, the entire member can be made elastic, so that the elastic cleaning tool 60 can be manufactured without foaming the core member 62. As a result, not only other foamed plastics but also various general plastics can be used as the core member 6.
2 can also be used.

It should be noted that there is no core member 62 and the mesh member 6
The cleaning tool may be manufactured by rolling only one. In this case, the cleaning tool has a higher elasticity than the case where the core member 62 is provided.

In the above embodiment, the cleaning tool main body having the mesh member 61 only on one surface of the core member 62 is used. However, the mesh member 61 is provided on both surfaces of the core member 62 instead. The cleaning tool body may be used. In that case, in the example of FIG. 9, the mesh member 51 of the overlapping portion is doubled. Further, in the example of FIG. 10, the mesh portion 61 also overlaps the overlapping portion 64 doubly. Thereby, the elasticity is further improved.

In the above embodiment, one cleaning tool body is spirally wound or folded to sandwich the mesh members 51 and 61 inside. However, the present invention is not limited to this. It may be laminated and rounded or cut into a rectangular parallelepiped. (Fifth Embodiment) FIG. 11 shows a fifth embodiment of the present invention. As shown in FIG.
0 is the mesh member 41 of the cleaning tool according to the third embodiment.
And a mesh-like member 69 as a sheet-like body having a metal lath shape. In the ridgeline portion 69b and the connecting portion 69c of the mesh-like member 69, the slope is inclined to form an edge.
The material of the mesh-like member 69 is the same as the material of the mesh-like member 41 of the third embodiment, and the fiber has a complicatedly entangled loop structure and a porous structure of the fiber itself. It is also preferable that a nonwoven fabric composed of microfibers (hereinafter referred to as a microfiber nonwoven fabric) is used as such a material.

Next, a method of manufacturing the cleaning tool 70 of the present embodiment will be described below. The manufacturing method is the same as that described in the third embodiment. Here, steps that need to be added particularly when a microfiber nonwoven fabric is used as the material of the mesh member 69 will be described.

Known microfiber nonwoven fabrics include, for example, Alcima (registered trademark) manufactured by Unitika Ltd. and SHALERIA (registered trademark) manufactured by Asahi Kasei Corporation.
Etc. Even if an attempt is made to form the cut 72 in such a microfiber nonwoven fabric, the cutter blade cannot penetrate sufficiently due to the low stiffness due to the fine structure of the fiber. Therefore, before pressing the blade of the cutter against the microfiber nonwoven fabric, it is preferable to impregnate a hardener such as glue. The curing agent may be sprayed and permeated into the microfiber nonwoven fabric. In addition to the curing agent, an antibacterial agent or an abrasive may be added to the microfiber nonwoven fabric. After that, when sufficiently dried, a microfiber nonwoven fabric having strong stiffness can be produced.

When the blade of the cutter is pressed against the microfiber non-woven fabric in this state, the blade is sufficiently penetrated through the micro-fiber non-woven fabric because the fibers of the pressed portion and the surrounding fibers are fixed. Can be
The cuts 72 having a desired arrangement can be efficiently formed. Here, the microfiber nonwoven fabric has a cut 72
It is sufficient that the stiffness is present when creating the cleaning tool, and when it is used as the cleaning tool 70, it may be soft.

When the sheet member 71 (FIG. 11A) having the cuts 72 formed as described above is pulled with an appropriate force in a direction in which the size of the cuts 72 is enlarged during use, the gap 69 is formed.
a spreads, and the edge stands as described above at the ridge portion 69b and the connecting portion 69c. In addition, not only is such a sheet member 71 pulled in a direction in which the size of the cutout 72 is enlarged before use, but also as shown in FIG. preferable. Note that even when the sheet member 71 is only rounded without being pulled before use, the cut 72 naturally expands when the sheet member 71 is rolled, so that an edge is formed to some extent.

Here, the term "rounding" means that the sheet member 71 is deformed from a sheet-like shape by applying an external force manually or by a machine, and the rounded shape of the sheet member 71 may be almost spherical. It may be close to a waveform.
Alternatively, the shape may be completely random. In short, any shape may be used as long as the edge of the cut 72 is at least partially raised when an external force is applied to the sheet member 71.

When the object is wiped using the sheet-shaped cleaning tool 70 formed in this manner, the standing edge of the mesh-like member 69 firstly removes large dirt or dust adhered to the surface of the object. It works to remove stubborn dirt and removes macro dirt. Next, the mesh member 6
9 attracts fine dust and fine particles adhering to the surface of the object by the fine loop structure or porous structure of the fiber itself or by the electrostatic action caused by the rubbing of the object with the mesh-like member 69, thereby removing micro-dirt. Remove. Further, the surface of the sheet-like cleaning tool 70 has a large surface area of the fiber due to the loop structure or the porous structure, and can effectively absorb moisture, oil, and the like.

As described above, the dirt on the object can be very effectively and efficiently removed by the synergistic effect of the macro dirt removing effect and the micro dirt removing effect.
Further, unlike a cleaning tool which is a normal sheet member 71 which is not a mesh-shaped member, the edge portion is caught by a hand, so that it does not slip when used, so that sufficient force is applied to an object. It also has the advantage that it can be wiped.

FIG. 12 shows a modification of the fifth embodiment. Thus, the cut 72 may not be formed in the entire sheet member 71 but may be formed only in a part thereof.
In this case, for example, as shown in FIG.
May be formed at the center of the sheet member 71,
It may be formed in the peripheral part as shown in FIG.
In addition, as shown in FIG. 12 (c), the cuts 72 may be distributed and distributed at regular intervals over the entire sheet member 71, or may be irregularly distributed as shown in FIG. 12 (d). They may be distributed at regular intervals in an irregular direction.
