DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool used for cleaning articles such as bathtubs, tiles, cooking utensils, and the like.

[0002]

2. Description of the Related Art Conventionally, sponges,
Body brushes, towels, etc. are known, and in recent years, various materials such as a cleaning net in which synthetic fiber net members are bundled and tied with a string, and a fiber cloth in which fine irregularities are densely grouped by special textile processing , Shapes are commercially available.

In combination with soap, a sponge is provided with a concave portion and a liquid detergent is poured into the concave portion so that an appropriate amount of detergent can be used, or the above-described net member or fiber cloth is processed into a bag shape to form a solid soap. By wrapping the, the user can save time and effort to attach a separate soap to the cleaning tool and foam it,
There are also known techniques for improving the convenience of the user, such as one in which a strap is attached to facilitate draining.

[0004]

However, for example, sponges are inexpensive but have poor durability, feel, and detergency.
On the other hand, body brushes are expensive, although they are rich in touch and detergency. In this way, the above conventional products are
The durability, feel, and detergency were balanced, and none of them had good performance, which was inconvenient.

[0005] In the case of a cleaning net in which a net member made of synthetic fiber is bundled and tied with a string, the net member comes off from the tied string as it is used, and its shape collapses and becomes unusable. . In addition, in the case of soap related to the improvement of convenience, if the sponge is provided with a concave portion and a liquid detergent is injected into it so that an appropriate amount of detergent can be used, the amount of soap used is excessive. In addition, it is not easy to replenish new soap with a solid soap contained in a bag-like net member or fiber cloth, especially if it is used for washing the body. Due to the presence of the solid soap, the feel became poor, and a separate strap had to be provided.

[0006] The present invention has been made in view of such conventional problems, and eliminates the inconvenience associated with the washing operation of the user. It is an object of the present invention to provide a cleaning tool capable of suppressing waste of soap and easily replenishing soap.

[0007]

Therefore, a cleaning tool according to the first aspect of the present invention has a tubular or bag-like net member mainly made of a flexible synthetic resin material. Are sewn together with a sewing string in the central axis direction in a region in the vicinity of the cylindrical or bag-shaped central axis, and the sewn area of the net member is reduced in the central axis direction to reduce the squeezed portion. The sewn string is bound so as to be formed, and the net member is configured to have a substantially spherical body with the entire envelope shape substantially centered on the drawn portion.

According to this, when the joint stitching area is squeezed with the column-shaped sewing string, the individual meshes of the net member are curved while expanding, and the entire net member has elasticity about the center of the squeezed portion. The cleaning tool has a substantially spherical envelope shape. For this reason, the net member made of synthetic resin is used to wash the surface to be washed with a strong washing power with a resilient coarse mesh to give the user a good feel and to sew both side surfaces of the net member together. It does not come loose during use.

In particular, as in the invention as set forth in claim 2, a net material made of a synthetic resin having elasticity and thermoplasticity is used as the net member, and at least a part thereof is heat-treated to obtain a suitable elastic force. In this case, the shape of the substantially spherical net member is maintained, and a good pressure contact force with the object to be cleaned is obtained. In the binding of the sewn string, the sewn string is wound around the squeezed portion one or more times to form a squeezed portion in which the co-sewn area of the net member is reduced to a small ring shape, as in the invention according to claim 3. The net member may be bound so as to form a substantially small ring shape obtained by turning, and the spiral shape is substantially swirled in a state where the co-sewing region of the net member is reduced in the center axis direction as in the invention according to claim 4. The inner and outer ends of the sewn string may be connected to each other through the net member.

[0010] In the invention according to claim 5, the number of the net members is not limited to one, but may be plural.
For example, as in the invention according to claim 6, a plurality of the net members are aligned in the central axis direction, and both side portions of these net members are aligned with the central axis in a region near the cylindrical or bag-shaped central axis. The joint region may be formed by sewing together with a sewing string in the direction, and a plurality of the net members may be arranged such that their central axes are substantially parallel to each other as in the invention according to claim 7. The two or more net members may be simultaneously stitched together at the same time to form the above-mentioned stitching region. And like the invention of claim 8,
Each of the plurality of net members is made of a synthetic resin net material having elasticity and thermoplasticity, at least one of which is heat-treated, and at least one of which is not heat-treated. , Combining net members having different elasticity and contractility.

Still further, as in the invention according to claim 9,
A plurality of the net members may be concentrically superimposed such that their respective central axes are substantially common, and both side portions of the plurality of net members may be simultaneously stitched to form the stitched region. Then, in this case, as in the invention according to claim 10, each of the plurality of concentrically polymerized net members is made of a synthetic resin net material having elasticity and thermoplasticity, and at least one of them. The outermost net member is heat-treated, and at least the innermost net member is not heat-treated, and the net members having different elasticity and shrinkage are combined.

[0012] The plurality of net members may be configured as follows.
As described in the invention described in (1), the cleaning power and the cleaning sensation may be changed as a configuration in which the physical conditions such as the thickness or the cross-sectional shape of the constituent fibers of the net are different from each other. In addition, by adjusting the mixture ratio of the different types of net members, a desired detergency or feel can be obtained. The stitching string that stitches together the joint stitching region may jointly stitch the net member with one stitching string as in the invention according to claim 12.
As in the invention described in Item 13, two substantially parallel sewing strings may be sewn in parallel at a predetermined interval.

[0013] Further, as in the invention according to claim 14, a solid detergent can be attached to the net member to eliminate the need for preparing a separate detergent. In this case, the cleaning tool according to the present invention is wetted with water or hot water and easily cleaned. As a method for mounting the solid detergent, claim 15
As described above, the solid detergent can be fixedly disposed in the narrowed portion, which is the central portion of the cleaning tool. Specifically, as in the invention according to claim 16, the solid detergent has an annular concave portion on the outer periphery of the central portion, and the solid detergent is stored in a storage bag, and the solid detergent is surrounded by the common detergent. A solid detergent can be fixedly arranged in the narrowed portion so that the sewing area surrounds the periphery of the annular recess and the sewing string surrounds the outer periphery of the joint sewing area. Further, as in the invention according to claim 17, in a state where the two solid detergents are stored in the storage bag, the co-sewing region surrounds the two solid detergents and is between the two solid detergents. As the sewing string surrounds a substantially formed annular recess around the outer surface of the co-stitching area,
A solid detergent may be fixedly provided in the narrowing portion. Further, as in the invention according to claim 18, the gourd which has an annular concave portion on the outer periphery of the central portion in the inner end of the common sewing area wound substantially spirally of the net member and is stored in the storage bag. A solid string detergent is stored, and a sewing string is wound around an annular concave portion of the solid detergent so that the co-stitch area is spirally wound around the solid detergent, and the inner and outer ends of the string are connected to the net. It can also be bound through a member.

In this way, when the joint sewing area is squeezed, the sewn string simultaneously bites into the annular concave portion of the solid detergent.
The solid detergent can be easily fixed to the net member. In this case, as in the invention according to claim 19, if the storage bag is configured to have at least one open end in which the solid detergent is freely inserted into and removed from the storage bag, a new solid detergent is provided through the open end. Exchange or supplement. If the storage bag uses the same net member, it is preferable because the foam and the drainage are good.

As another method of attaching a solid detergent to the net member, the solid detergent may be disposed in the narrowed portion between two sewing strings as in the invention according to claim 20. .
With such an arrangement, the solid detergent is entirely wrapped by the two sewn strings and the common sewing area of the net member, and can be fixedly mounted on the net member with good fit. The solid detergent does not necessarily need to be fixedly mounted in the drawn portion of the net member.
For example, as in the invention described in claim 21, the solid detergent may be fixedly mounted on the surface of the substantially spherical net member so that the solid detergent can be visually recognized. With this configuration, the solid detergent can be easily fixed and attached to the net member with a string, or the storage bag containing the solid detergent can be fixed and attached with the magic tape, thereby simplifying the production. Further, as in the invention according to claim 22, in a configuration in which at least one solid detergent is mounted inside an unheated net member made of the stretchable and thermoplastic synthetic resin net material, the heat treatment is performed. The solid detergent is stably held by the shrinkage of the net member which has not been made.

It can be generally said that the tubular or bag-shaped open end of the net member has a problem in that the cut end of the net member may damage the surface to be cleaned, or the skin feels. When there is a risk of damage, it is preferable that the open end is folded inward so that the cut end does not protrude from the surface to be cleaned, as in the invention described in claim 20.

[0017]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows the appearance of a cleaning tool according to an embodiment of the present invention, in which a hanging strap 20 is attached to a substantially spherical body 10 having a substantially spherical overall envelope shape. Such a cleaning tool is manufactured through the steps shown in FIG. That is, the tubular net member 11 forming a mesh or a bag-like net member 11 whose one open end is closed is flattened, the opposite side portions 11a and 11b of the net member 11 are overlapped, and the cylindrical central axis l is set. Simultaneous sewing is performed in the vicinity area by the sewing string 12 in the direction of the central axis l. As a result, due to its flexibility, the net member 11 has a resilient bulge having a loop-shaped cross section on both sides of the sewing string 12.

The joint region 13 of the net member 11
To reduce the length in the direction of its central axis.
The both ends of 12 are turned in the direction of the arrow in FIG. 2C, and are connected in a small ring shape as shown in FIG. As a result, the joint sewing area 13 is narrowed by the small annular sewing string 12 and contracts in the direction of the central axis l, and the net member 11 expands around the narrowed portion 14 with elasticity.

The expanded shape of the net member 11 forms a substantially spherical body 10 centered on the narrowed portion 14 of the net member 11. The hanging strap 20 is tied to the sewn string 12 or wound around the sewn area 13 outside the sewn string 12 to be tied. The strap 20 itself may be extended to form the strap 20. In addition, sewing string
12 may be bound in a single small ring shape, or an appropriate number of times,
By winding around the outside of the throttle unit 14 and binding,
You may make it bind | bond together in the multiple ring shape.

The net member 11 is preferably composed mainly of a flexible synthetic resin which forms a mesh, for example, a commercially available polyethylene resin (trade name: Netron, manufactured by Mitsui Chemicals, Inc.). That is, generally, a commercially available net member has a cylindrical shape, and the shrinkage is too strong in a direction perpendicular to the center axis l (referred to as a lateral direction). Will be reduced,
Despite the use of a flexible material, it has a hard feel and feels poor. Therefore, in the present embodiment, for example, a shrinkable / flexible polyethylene resin having thermoplasticity is selected from many materials, and only a heat treatment is performed to obtain a substantially spherical shape having desired shrinkage / flexibility. Can form body. In other words, it is possible to use an inexpensive tubular net material that is frequently used for packaging and distribution of food products such as oranges for the net member 11, and as a result, the manufacturing cost can be significantly reduced. Become.

The heat treatment of the netron may be performed by blowing hot air at 60 to 90 ° C. for about 3 to 10 seconds. The net member 11 has a cylindrical shape having openings 15a and 15b at both ends by cutting a long cylindrical net material wound in a reel shape into an appropriate length as shown in FIG. Then, as a pre-treatment, the above-described heat treatment is performed using a heat source such as an iron and a dryer to obtain desired shrinkage and mesh size.
Although a commercially available net member wound in a reel shape is used, a net member already formed in a bag shape may be used because the net member is used for distribution of foodstuffs and the like.

The openings 15a and 15b at both ends of the cut net member 11 have a shape in which the fibers constituting the mesh protrude to the outside, which deteriorates the feel of the body to be cleaned such as the skin.
As shown in FIG. 2 (b), the sewing machine is sewn together with the opening 12 at both ends folded inward so as to pass the sewing string 12 when sewing. As a result, the folded ends 16a and 16b maintain the folded positions.

As described above, the cleaning tool formed into a substantially spherical body applies a detergent to the net member 11 to clean the surface to be cleaned such as the skin. Then, the foam of the detergent foams well on the net of the net member 11 and spreads well. Here, since the net member 11 is made of a flexible synthetic resin, the skin surface of the skin can be effectively washed with an appropriate frictional force, and a good feeling can be given to the user. Because of the good drainage, it can keep cleanliness. Further, the net member 11 mainly made of synthetic resin can be provided to the market at a low price. Further, the opposite side portions 11a and 11b of the net member are simultaneously sewn together with the sewing string 12, so that the net member 11 does not come loose during use, and has high durability.

Although the joint stitching of the net member 11 is performed by sewing with one sewing string 12 in the vicinity of the center axis l, a plurality of sewing strings 12 may be used, and even if the center axis l is slightly deviated. Alternatively, the sewing may be performed in such a manner as to be inclined with respect to the center axis l or to draw a slightly curved line. In short, net members 11
This is only required to be formed on the substantially spherical body 10 when sewn down.

The sewn string 12 also includes a string, a band, a chain, and the like in addition to the string, and may have any shape as long as the net member can be narrowed down by sewing together.
The material of the sewing string 12 is not limited to animal and plant fiber products, leather products, synthetic resin products, and metal products, but should be appropriately selected according to the surface to be cleaned. Needless to say, in addition to tying the string, the sewing string 12 can be arbitrarily selected from hooking, magic tape, and other known fastening means.

If the strap 20 is used, the washing tool can be conveniently used by hanging it in a washroom, a bathroom, a kitchen, or the like. In addition, when the sewn string 12 is tied in FIG. 2D, the sewn string can be easily attached by tying the sewn string together to the ring-shaped strap 20,
Further, in the present embodiment, the strap 20 is separately prepared. However, the strap 20 may be tied so as to form a loop with the sewing string 12, and may be used as a substitute for the strap 20.

In the above-described embodiment, the cleaning tool is manufactured using the single net member 11, but the present invention is not limited to this, and the cleaning tool can be manufactured using a plurality of net members. For example, as shown in FIG. 3, a plurality of net members 21a, 21b, 21c,-in which both end openings 15a, 15b are folded inward are aligned in the direction of the center axis l, and the opposite side portions of the respective net members are arranged. Can be integrally sewn together in the direction of the central axis l in the direction of the central axis l in the cylindrical or bag-like shape, and the sewn string 12 can be tied to narrow the joint sewn area 13. .

As shown in FIG. 4, a plurality of net members 31 are provided.
a, 31b, 31c, --- are respectively set to the respective central axis lines l1, l2, l3, ---
Are superimposed so as to be substantially parallel to each other, the opposite side portions of the plurality of net members are simultaneously sewn together along the central axis l, and the sewn area 13 can be narrowed down by using a sewing string 12. It is possible. Further, as shown in FIG. 5, a plurality of net members 41a, 41b, 41c,... Are concentrically superimposed such that their central axes l are substantially common, and the relative positions of these plurality of net members are It is also possible to simultaneously sew both side portions to be sewn, and narrow down the sewn area 13 with the sewing string 12.

In these cases, the plurality of net members may be appropriately combined with those subjected to the heat treatment, and the size and elasticity of the cleaning tool may be changed so as to adjust to the user's hand. it can. In the case where a plurality of net members as shown in FIG. 5 are concentrically superimposed, the elasticity of the heat-treated net member may be impaired if the non-heat-treated net member having shrinkage force is arranged inside. Nor.

Furthermore, if the physical conditions such as the thickness, material, and cross-sectional shape of the constituent fibers of the nets are made different from each other, and the mixing ratio of different types of net members is adjusted, sewing can be performed as desired. It becomes possible to obtain detergency or touch. Next, a cleaning tool according to another embodiment of the present invention shown in FIGS. 6 and 7 will be described. This embodiment shows a cleaning tool in which a solid detergent 56 is included in the narrowed portion 14 of the joint area 13 of the net member 11 described above, and the same reference numerals are given to the same components as those in the embodiment of FIG. . The solid detergent is used by being wrapped in a storage bag 53 as shown in FIG. 7B. The storage bag 53 cuts a net material made of the same material as the net material wound in a reel shape into an appropriate length, and has openings 55 at both ends as shown in FIG.
A tubular net member 51 having a and 55b is prepared, and both ends thereof are folded inward to a plurality of layers (three in this embodiment) and sewn. Then, with the solid detergent 56 disposed inside, the strings 52 are inserted through the peripheral edges of both ends and tied to form the openings 55a, 5
5b is closed, and the solid detergent 56 is stored in the storage bag 53. In practice, one opening 55a is closed first to form a bag, and then the solid detergent 56 is inserted through the other opening 55b,
Thereafter, the other opening 55b is closed.

Here, the diameter of the net material is reduced to match the size of the detergent by folding the net material having the same size as that of the net material used in the previous embodiment. Of course, a net member having a small diameter may be used simply because the mass production cost can be reduced by eliminating the need to prepare a net material of another size.

The net material in this step is not subjected to a heat treatment as a pre-treatment, and a material having strong elasticity is used as it is. As a result, the solid detergent 56 can be stored in the storage bag 53 with a contracting force, thereby preventing the solid detergent 56 from floating and avoiding unnecessary friction with the net member 11 to use a large amount of the detergent unnecessarily. Was prevented. In the present embodiment, the solid detergent 56 is formed into a so-called gourd shape having an annular concave portion 56a provided at an intermediate portion in the longitudinal direction, as shown in FIG. 7A, or shown by 56b and 56c in FIG. 7D. A configuration in which two spherical objects are arranged and stored in the storage bag 53 is adopted. Then, from the outer surface of the storage bag 53 to which the solid detergent 56 is delivered, a substantially annular concave portion formed in the annular concave portion 56a of the solid detergent 56 or an intermediate portion between the two spherical solid detergents 56b and 56c.
In the state where the outer periphery of 56d is wrapped with the string 57 as shown in FIG. 7B or directly without using the string 57, when the net member 51 is sewn together, as shown in FIG. It is made to wind at the same time with the string 12. As a result, the solid detergent 56 can be fixedly stored in the joint sewing narrowing portion 14 of the net member 51.

By adopting such a structure, it is not necessary to attach a separately prepared detergent at the time of washing, and the solid detergent 56
Is not exposed and therefore does not impair the feel. Since the storage bag 53 is also made of a synthetic resin net material, the drainage is good, the swelling of the solid detergent 56 can be prevented, and the use amount of the detergent does not increase unnecessarily. Further, the sewing member 12 is engaged with the annular concave portion 56a of the solid detergent 56 or the substantially annular concave portion 56d between the two spherical solid detergents 56b and 56c, and the net member 51 is stored in the storage bag 53.
The solid detergents 56, 56b, 56c are prevented from being detached suddenly by using a storage bag 53 made of a net member that can be firmly fixed and has strong elasticity.

When the solid detergent 56 has been consumed or has been used up, the string 52 at at least one of the open ends can be easily refilled with a new detergent for refilling. It becomes possible to continuously use the storage bag 53 without throwing it away once. The string
Instead of 52, it is also possible to adopt a configuration that can be easily opened and closed by closing with an elastic member such as rubber, attaching with a magic tape, or binding with a band-shaped member.

It is also possible to store the solid detergent 56 directly in the narrowed portion 14 of the joint sewing area 13 of the net member 11 without using the storage bag 53. For example, as shown in FIG. 8A, a plurality of, for example, two stitches 12a,
At 12b, the sewing is sewn in parallel with the center axis l of the net member 11 at a predetermined distance, and a solid detergent 66 is disposed between the two sewn strings 12a, 12b. As shown in FIG. 8B, the joint sewing area 13 becomes a bag-like shape, wraps the solid detergent 66, and the sewing strings 12a and 12b close the opening of the joint sewing area 13. Thereby, the solid detergent 66 can be mounted on the central portion of the net member 11 without using the net-like storage bag, which is economical and easy to manufacture. If one of the sewing strings 12a and 12b is untied, the detergent can be replenished. After refilling, reopen the opening with the sewing string 12a or
Tying and closing 12b would make it available for reuse. In the present embodiment, the shape of the solid detergent does not matter.

FIG. 9 shows another embodiment of the present invention in which a net member is spirally wound and a solid detergent is accommodated therein. That is, the relatively long net member 61
As in the above-described embodiment, the both ends 11a and 11b are overlapped and sewn together with a sewing string 12 as in the above-described embodiment.
The gourd-shaped solid detergent 65 stored in the storage bag 53 is sewn into one end of the joint sewing area 13. Specifically, FIG.
As shown in (a), the joint sewing is not performed near one end of the net member 61, and the solid detergent 65 is stored between both sides of the one end. Then, from one side of the one end, the sewing string 12
Is sewn along the center axis, and moved to the other end at the tip of the folded back of the net member, and after reaching the other side,
The tip of the sewing string 12 is hung outside. Next, FIG.
As shown in (b), the co-sewing area 13 of the net member is used.
9A, the sewing string 12 is wound around an annular recess of the solid detergent 65 with one end containing the solid detergent 65 as an inner end, as shown in FIG. 9C. The sewn area 13 is wound in a substantially spiral shape and polymerized,
Finally, the inner and outer ends of the sewn string 12 are connected to each other through the mesh of the net member 61. The sewing string 12 is substantially formed in a small-ring shape with a plurality of turns, and is the same as the single-turn small ring shape in the previous embodiment in which the sewing string 12 is bound. However, in the present embodiment, since the net member 61 is configured to be wound multiple times, the amount of the net member increases,
The result is a heavy cleaning tool.

When the present embodiment is used as a cleaning tool without a solid detergent, the solid detergent is not stored at one end of the joint sewing area 13, and therefore, the joint sewing is performed over the entire area of the net member. Then, after spirally winding from the inner end to the outer end, both the inner and outer ends of the sewing string 12 may be bound through the mesh of the net member. The mounting of the solid detergent on the net member was, according to the previous embodiments, within the squeezed portion of the net member, but in a configuration using a net member including a portion not subjected to heat treatment, the solid detergent is applied to the portion not subjected to heat treatment. You may arrange | position and hold | maintain with the contraction force.

For example, in the configuration shown in FIG.
As shown in FIG. 10 (a), both ends 18a and 18b of the net member 11 are provided with portions which are not subjected to the heat treatment, and the both ends 18a and 18b are placed inside the net member 11 as shown in FIG. 10 (b). Fold it in. And both ends 18a and
A desired number of solid detergents 67 are provided in the inside 18b, and the net member 11 is sewn together with the sewing string 12 as in the above-described example of FIG. The cleaning tool has a substantially spherical shape as shown in (1).

In this manner, the solid detergent 67 can be reliably held by the shrinkage of the portions 18a and 18b of the net member 11 where the heat treatment is not performed. Further, when the solid detergent 67 is consumed, it can be easily replenished from the openings 19a and 19b of the net member 11 located on both sides of the squeezed portion 14, so that it can be used repeatedly for a long period of time. .

On the other hand, in a cleaning tool composed of a plurality of net members including those not subjected to heat treatment, a solid detergent may be provided at an arbitrary position inside the net member not subjected to heat treatment. . For example, in the configuration shown in FIG. 3, when the net member 21b is a non-heat-treated net member, as shown in FIG.
Arrange the desired number of solid detergent 68 at any position inside,
The opposite side portions of each net member are sewn in the direction of the central axis l in a region near the cylindrical or bag-shaped central axis l.
To stitch together to bind the stitching string 12 to narrow the joint stitching area 13. As a result, as shown in FIG. 11 (b), the solid detergent 68 is stored inside the fold-shaped net member 21b. Net member 21b without heat treatment
Has a shrinkage property, so that the solid detergent 68 can be prevented from floating inside the net member and can be reliably held.

As shown in FIG. 12, a solid detergent may be attached from outside the net member. In this case, a solid detergent 76 is contained in a storage bag 73, and ends of the cord 72 are bound to both ends of the storage bag 73, respectively. Then, the storage bag 73 containing the solid detergent 76 is disposed on the surface of the net member 11, and the string 72 is tied to the sewing string 12 of the net member 11 and fixed. Sewing String 72 String 12
Alternatively, the string 72 may be passed through the net member 11, and these may be connected to each other at both ends. In this case, the production is simplified, the production cost can be reduced, the solid detergent alone can be disposable, and the user can visually check the consumption state of the solid detergent from outside, and furthermore, the solid detergent ,
By taking into account the color tone and color of the storage bag and the net member as appropriate, it is possible to provide a decorative effect that goes beyond the feeling of conventional cleaning tools, such as giving a shape like a rose flower with a solid detergent as a flower core. Have and aesthetic.

[0042]

As described above, according to the first aspect of the present invention, both sides of a tubular or bag-shaped net member mainly made of a flexible synthetic resin material are sewn together with a sewing string to reduce the size. Since the drawn portion is formed in this manner, a cleaning tool having a substantially spherical envelope shape in which the entire net member has elasticity around the drawn portion can be obtained with a simple operation. As a result, the net member made of a low-cost synthetic resin as a main material can clean the surface to be cleaned with a strong cleaning power with a resilient coarse mesh, giving a good feeling to the user, and also provide both sides of the net member. Since the surfaces are sewn together, they do not unravel during use, maintain a beautiful appearance, are rich in decorativeness, and have high durability.

In particular, according to the invention as set forth in claim 2, since the net member is formed so as to obtain an appropriate elastic force by heat-treating a stretchable and thermoplastic synthetic resin net material, a substantially spherical body is formed. The maintenance of the shape of the net member is maintained, a good pressure contact force with the object to be cleaned is obtained, and an appropriate feel and cleaning power are obtained. According to the third and fourth aspects of the present invention, the squeezed portion can be formed by simply reducing the joint area of the net member by simply attaching the sewn string.

According to the fourth aspect of the present invention, since the seam area of the net member is spirally wound and polymerized, the cleaning tool can be easily formed to have a large diameter. In the invention according to claims 5 to 10, since the number of the net members is not limited in forming the cleaning tool, the selection range of the net material can be increased. In particular, claim 8 and claim 10
The size and elasticity of the cleaning tool can be adjusted by appropriately combining net members having different elasticity and contraction force depending on the presence or absence of heat treatment.

According to the eleventh aspect of the present invention, since the physical conditions such as the thickness or the cross-sectional shape of the net constituting fibers of the net member are different, it is possible to change the detergency and the feeling of cleaning. By adjusting the mixture ratio of the different types of net members, it becomes possible to obtain a desired detergency or feel. According to the inventions set forth in claims 12 and 13, since the net member can be sewn together with one or two stitches, the work is easy.
