Description

  The present invention relates to a cleaning tool convenient for washing the body and face with fine bubbles, classified into a body for rubbing the body to wash the body, a face washing for washing the face, and a lather for making a large amount of fine bubbles. Applicable to all

  Conventionally, many washing tools for lathering for foaming solid or liquid soap, and many washing tools for body or face washing for washing the body and face while keeping the soap component lathered are proposed and marketed. Has been. For example, Patent Literature 1 discloses a foaming net for facial washing used for foaming soap for facial washing at the time of facial washing.

  The foaming net disclosed in Patent Document 1 is for face washing, and the upper and lower ends of a cylindrical plastic net having fine stitches of several millimeters in length and width are gathered together, and one end thereof is a binding tool. In this state, it is folded back inward and a finger insertion ring is attached to the other end. This foaming net for face washing can make silky and soft foam by applying a suitable amount of soap to water soaked in warm water or warm water, and squeezing or spreading it by hand.

  However, in order to use the face-washing foaming foam, the face-washing foaming net must always be rubbed or spread in both hands, which imposes a burden on the user. . Moreover, the conventional foaming net for face washing is comprised so that foam may be foamed only on the surface of a cylindrical plastic net. For this reason, the conventional foaming net for face washing cannot hold a large amount of foam in its interior, so a large amount of foam cannot be foamed at once, and it can be used by rubbing the body as a cleaning tool for washing the body. Insufficient foaming.

  Patent Document 2 also discloses a whisk applied to face washing. Patent Document 2 includes an inner fibrous member having resilience as an inner member, a fibrous member having a finer stitch than the inner fibrous member, and a core material further included in the inner fibrous member. There is disclosed a whisk for a face washing composed of a substantially spherical body from a central fibrous member. This face-washing whisk is made by repeatedly folding the inner fibrous member and the fibrous member several times, and is fixed with a fixing thread or the like. And by inserting a substantially spherical central fibrous member inside the fixed inner fibrous member, there is an eight-layer structure (there is no detailed explanation, but the central fibrous member has a five-layer structure from the drawing) If combined, it is formed into a 13-layer structure).

  In this whisk for face washing, the inner fibrous member has elasticity, so when it is squeezed by hand to make foam, it can immediately return to its original shape, and it can rub per unit time. You can increase the number of times you can. Thereby, the whisk for face washing can increase the quantity of the air which passes an inner side fibrous member and a fibrous member, and can foam a lot of foam in a short time.

  Patent Document 3 discloses a body cleaning tool that is used by rubbing directly on the body in order to wash the body. This cleaning tool is formed in a quadrangular pyramid shape (substantially pyramid shape) having a substantially square bottom surface, and is assembled as follows. First, two joining net bodies are formed by overlapping and joining adjacent sides at each corner of a net formed in a square sheet shape. And in the state which aligned each corner | angular part of these both joining net bodies, one joining net body is arrange | positioned inside the other joining net body, it is set as a double structure, and both these joining net bodies are turned over. And each corner | angular part of both the joining net bodies of the state turned over is raised and integrated.

  In this cleaning tool, since it is configured in a double structure by two joining net bodies, foam can be held not only in the outer part but also in the inner part and also in two joining net bodies. . Further, the cleaning tool is formed in a substantially pyramid shape (substantially pyramid shape) by raising each corner portion of the bonded net body. Thereby, a passage is formed between the corners, and air easily enters the bonded net along the passage, so that the facial cleanser can be sufficiently bubbled.

  However, the whisk for facial cleaning described in Patent Document 2 is a plastic net simply assembled into a 13-layer structure, so it has poor elasticity and its shape collapses when rubbed against the body when washing the body. As a result, there is a problem that sufficient bubbles cannot be held inside, and the bubbles cannot be efficiently formed.

  Moreover, although the cleaning tool described in Patent Document 3 is used by being rubbed against the body, since the net of the square sheet is simply folded and overlapped, the foam for facial cleansing disclosed in Patent Document 2 is used. Like a container, when it is used with rubbing against the body, its shape will collapse, it will not be able to hold enough foam inside, and it will not be possible to foam efficiently. .

  An object of the present invention is to provide a cleaning tool that has a suitable elasticity and is suitable for repetitively squeezing a hand-held cleaning tool to produce a large amount of foam.

  It is a further object of the present invention to provide a cleaning tool that can hold a large amount of foam inside.

  A further object of the present invention is to provide a cleaning tool capable of producing a large amount of fine bubbles.

  It is a further object of the present invention to provide a cleaning tool that is not easily deformed.

According to the present invention, the above problem is
An outer surface member with many water holes,
An inner member made of a plastic material and having a large number of water passage holes,
The outer surface member is cylindrical, the cylindrical outer surface member is folded halfway, and an accommodation space surrounded by the inner cylinder part and the outer cylinder part formed thereby is formed,
This is achieved by providing a cleaning tool characterized in that the inner member is housed in the housing space of the outer surface member in a state of being contracted in a bellows shape.

  According to the cleaning tool of the present invention, the inner member made of a plastic material can be made to exhibit an appropriate elasticity by being brought into a bellows-like state, and the inner member in a bellows-like state is bulky. Therefore, a large amount of bubbles can be produced while enclosing a large amount of air in the process of massaging by hand, and a large amount of bubbles can be held inside.

  In the case of a body or face cleaning tool that comes into contact with the skin, the outer surface member may be a material containing a natural material such as 100% cotton, cotton blend, silk, silk blend, etc., which is a skin-friendly natural material. There is a problem that it is difficult to achieve good foaming when natural materials are used because this kind of cleaning tool is gentle to the skin, but according to the present invention, the inside is formed of a plastic material and contracted into a bellows shape. Since the member is housed in the outer surface member, the inner member can provide a cleaning tool that is gentle to the skin while ensuring appropriate elasticity.

  On the other hand, since the cleaning tool for lathering is hand-rubbed to produce a large amount of silky bubbles, the outer surface member is preferably made of a material such as nylon, polyester, rayon, or tetron, which are artificial materials. Nylon, polyester, etc. have less repulsive force when wet, and it is difficult to ensure favorable resilience when making a foaming cleaning tool using only this material. Until now, nylon, polyester, etc. The material whose repulsive force decreases when it gets wet with water is a material that feels good but has been shunned as not suitable for a lathering cleaning tool. Since an internal material that can be secured is included, an appropriate elasticity can be secured by this internal material, so that materials such as nylon and polyester can be applied as the outer surface member.

  A polyethylene net or mesh knit has a problem of being easily torn. However, polyethylene nets or knits are characterized by excellent elasticity, and the polyethylene nets or knits are accommodated in the outer surface member so as not to be exposed to the outside, so that the polyethylenes are easy to tear. It is possible to provide a cleaning tool that makes use of the elasticity that is an advantage of the net or mesh knit. That is, it is possible to provide a cleaning tool that is not easily torn, has a good touch, and has good foaming.

  In a preferred embodiment, the hole in the outer surface member is smaller than the hole in the inner member. Thereby, since the foam produced | generated by the inner member becomes small when passing the hole of an outer surface member, a fine foam can be produced | generated.

  The above-mentioned technical problems and the effects of the present invention will become apparent from the following description of preferred embodiments of the present invention.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

First Example (FIGS. 1 to 12) :
1 is a front view of the cleaning tool 10 of the first embodiment, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG.

  As shown in FIGS. 1 to 3, the cleaning tool 10 of the first embodiment includes a substantially spherical main body 12 and an annular strap 14 attached to the main body 12. As will be described later, the cleaning tool 10 is used by being directly rubbed against the body while taking a bath while taking a bath. Of course, you may use without putting soap.

  The main body 12 includes a mesh-like knit member 16 as an outer surface member, a plastic net member 18 as an internal net member, a ring 20 and a binding tool 22, but the ring 20 may be omitted.

  The mesh-shaped knit member 16 is originally a cylindrical member having openings at both ends (see FIG. 4 described later), and is folded back via a ring 20 when assembled as the main body 12 (a diagram described later). 7), a donut shape. As shown in FIG. 2, here, the inner cylindrical portion of the mesh-shaped knit member 16 having a donut shape is referred to as an inner cylindrical portion 16a, and the outer swollen portion is referred to as an outer surface portion 16b. A plastic net member 18 to be described later is accommodated in a space 17 surrounded by the inner cylindrical portion 16a and the outer surface portion 16b (see FIGS. 2 and 3).

  The plastic net member 18 is originally a cylindrical member having openings at both ends (see FIG. 5 to be described later), and when assembled as the main body 12, the doughnut-like shape described above is contracted in a bellows shape. (See FIG. 2). Thus, since the plastic net member 18 is accommodated in the mesh-like knit member 16 by being contracted in a bellows shape, the plastic net member 18 has a higher elasticity and retains a large amount of moisture therein. Can do.

  Next, the configuration of the mesh knit member 16 will be described in detail with reference to FIG. 4A and 4B are diagrams showing the configuration of the mesh-like knit member 16 as the outer surface member, in which FIG. 4A is a perspective view and FIG. 4B is a partially enlarged view thereof. In FIG. 4, a cylindrical shape before being assembled as the main body 12 is shown.

  As shown in FIG. 4, the mesh knit member 16 is formed in a cylindrical shape having square or rhombus stitches, that is, through holes 16, which are well-known in the vertical and horizontal directions. Openings 16d and 16e are provided. The size of the mesh-like knit member 16 shown in the figure is 400 mm in height and 160 mm in diameter of the openings 16 d and e so that it can be easily held by hand when assembled and used as a cleaning tool. It is.

  The mesh knit member 16 has a fine mesh, that is, a through hole 16f, than the plastic net member 18 as an inner net member. In the present embodiment, the size of the mesh, that is, the through holes 16f of the mesh-like knit member 16 is 2 mm (h1) in length, as shown in FIG. The width is 1 mm (w1).

  Next, the configuration of the plastic net member 18 will be described in detail with reference to FIG. 5A and 5B are diagrams showing the configuration of the plastic net member 18 according to the present embodiment. FIG. 5A is a perspective view, and FIG. 5B is a partially enlarged view thereof. In FIG. 5, a cylindrical shape before being assembled as the main body 12 is shown.

  As shown in FIG. 5, the plastic net member 18 is a cylindrical plastic molded product having rhombic through holes 18c in the vertical and horizontal directions, substantially the same as the mesh knit member 16 described above. Openings 18a and 18b are respectively formed in each. The plastic net member 18 is formed so that the length in the major axis direction is approximately twice the length in the major axis direction of the mesh knit member 16. This is to provide higher elasticity when the plastic net member 18 is formed in a bellows shape. As for the size of the plastic net member 18 shown in the figure, the height of the cylinder is 800 mm, and the diameters of the openings 18 a and 18 b are 100 mm.

  As described above, the plastic net member 18 has a characteristic of shrinking in the radial direction as known, and can be expanded in the radial direction by applying an external force. In the embodiment, the height is twice as long as that of the mesh-like knit member 16 in the state where no external force is applied, but this is a predetermined elasticity when contracted in a bellows shape as described above. The length dimension of the plastic net member 18 can be arbitrarily set according to how much elasticity is exhibited. Further, the diameter (100 mm) of the opening of the plastic net member 18 is smaller than the diameter (160 mm) of the opening of the mesh knit member 16, that is, the plastic net member 18 is thinner than the mesh knit member 16. It is a cylindrical net. Therefore, when the plastic net member 18 is put on the inner cylindrical portion 16 a of the mesh-like knit member 16, the plastic net member 18 can be strongly adhered by the elastic force of the plastic net member 18.

  Further, as described above, the plastic net member 18 has a mesh larger than the mesh knit member 16, that is, a through hole 18c having an opening area larger than the through hole 16f of the mesh knit member 16 (FIG. 4B). is doing. Since the plastic net member 18 has a large mesh, the plastic net member 18 has higher stretchability and elasticity than the mesh-like knit member 16, and also has a characteristic that water drains well. In other words, fine bubbles can be made by setting the size of the through-holes 16f of the mesh knit member 16 constituting the outer surface member to be relatively small. In the first embodiment, the size of the mesh of the second net 18, that is, the through hole 18c, is 6 mm (h2) in length and 3 mm (w2) in width as shown in FIG.

  In the first embodiment, the plastic net member 18 is a plastic molded product made of, for example, polyethylene (PE), polypropylene (PP), polyamide (PA) or the like. On the other hand, the mesh knit member 16 may be a plastic molded product made of the same material as the plastic net member 18, but may be nylon, polyester, rayon, or a blend of these. The mesh knit member 16 constituting the outer surface member may be a non-woven fabric, towel fabric, or gauze fabric having a large number of water passage holes. Preferred materials include cotton, silk, hemp, A material containing a natural material such as a blend is preferable because it is gentle to the skin. For example, Unitika Co., Ltd. manufactures and sells cotton nonwoven fabric `` Bemiliese '' (registered trademark). This cotton nonwoven fabric is a material with many water passage holes through which soapy water can pass, Since it has a gentle and soft texture, it can be preferably employed. Japanese Patent Application Laid-Open No. 2002-191527 (Japanese Patent Application No. 2000-391687) discloses a porous body towel made of a natural fiber woven fabric, and this towel fabric can also be preferably used.

  In order to generate fine bubbles, the mesh knit member 16 constituting the outer surface of the main body 12 has a small stitch of about several millimeters (about 1 to 4 mm). Is preferred. The plastic net member 18 that is an internal member surrounded by the mesh knit member 16 is preferably a through hole 18 c having a size larger than that of the mesh knit member 16.

  As shown in FIG. 2, the ring 20 is a plastic molded product, and has a hole 20 a through which the mesh knit member 16 is passed. As described above, the mesh-shaped knit member 16 is turned through the hole 20a of the ring 20 and turned over so that the donut-shaped net housing space for accommodating the plastic net member 18 formed in a bellows shape is mesh-shaped. It is formed by the knit member 16. Thus, if the ring 20 (the lower end part of the main body 12) is collected, the cleaning tool 10 can be formed in a substantially spherical shape by a simple assembly process. Of course, instead of the plastic ring 20, it may be sewn with a thread or string.

  An annular strap 14 is attached to the upper part (in the drawing) of the cleaning tool 10 as shown in FIG. The strap 14 is attached by being bound by a binding tool 22 together with both end portions (bundling portion 16c) of the mesh-like knit member 16 folded and gathered at one end of the fixing portion 14b. If the cleaning tool 10 is suspended on a hook or the like by the strap 14, the moisture accumulated in the inside can be dried and the generation of mold or the like can be prevented. In addition, as the binding tool 22, for example, a flexible linear member that can be easily bent and deformed, such as rubber, thread, and string, is appropriately selected and used.

  The configuration of the cleaning tool 10 according to the first embodiment has been described in detail above. Next, a method for assembling the cleaning tool 10 configured as described above will be described in detail. 6-12 is a figure for demonstrating the assembly method of the cleaning tool 10 of 1st Example. In the description of the assembling method, steps will be described, but the assembling order is not limited, and the assembling order can be changed as appropriate.

Step 1 (preparing mesh knit member 16, plastic net member 18, and ring 20) :
First, as shown in FIG. 6, a cylindrical mesh knit member 16, a plastic net member 18, and a ring 20 each prepared to a predetermined size are prepared.

Step 2 (pass the mesh knit member 16 through the ring 20) :
The mesh-like knit member 16 is passed through the hole 20a of the ring 20 (in the direction of arrow b in FIG. 6), and the ring 20 is arranged in the middle of the mesh-like knit member 16. Specifically, first, the opening 16e side of the mesh knit member 16 is gathered so that the mesh knit member 16 passes through the hole 20a of the ring 20. And the opening part 16e side of the mesh-like knit member 16 put together is passed through the hole 20a of the ring 20. Next, the ring 20 is moved so as to slide on the surface of the first net 16 and is arranged in the middle of the mesh knit member 16 (see FIG. 7).

Step 3 (Plastic net member 18 is put on mesh knit member 16) :
The plastic net member 18 is put on the mesh knit member 16 while being contracted in a bellows shape (in the direction of arrow a in FIG. 6). Specifically, first, the opening 18b of the plastic net member 18 is extended outward and spread, and the mesh knit member 16 is covered. Next, while the plastic net member 18 is contracted in a bellows shape, the opening 18b is covered until reaching the ring 20, and is disposed so as to cover the substantially upper half of the mesh-like knit member 16 (see FIG. 7).

Step 4 (fold back the mesh-like knit member 16) :
The mesh knit member 16 is folded outward (in the direction of arrow c in FIG. 7). Specifically, first, the opening 16e side of the mesh-shaped knit member 16 is turned upside down through the ring 20 so as to wrap the bellows-shaped plastic net member 18 (in the drawing). Then, the folded opening 16e of the mesh knit member 16 is combined with the other opening 16d of the mesh knit member 16 to form a binding portion 16c, and the main body 12 is assembled into a substantially spherical shape (see FIG. 8). As shown in FIG. 8, a cylindrical space is formed at the center of the main body 12 assembled in this way by the inner cylinder portion 16a of the mesh-like knit member 16, and a strap 14 described later is provided in this space. Threaded inside.

Step 5 (attach the strap 14) :
In step 4 described above, the strap 14 is attached and fixed to the mesh knit member 16 formed in a substantially spherical shape. Specifically, first, as shown in FIG. 9, the strap 14 is inserted into the inner cylinder portion 16a from the opening portion 16d of the mesh knit member 16 (in the direction of the arrow d in FIG. 9), and the fixing portion 14b is It arrange | positions so that it may align with the binding part 16d of the mesh-shaped knit member 16. FIG. Then, as shown in FIG. 10, the bundling tool 22 ties the bundling portion 16 c of the mesh knit member 16 and the fixing portion 14 b of the strap 14 together to fix the strap 14.

Step 6 (pulling the strap 14) :
The strap 14 fixed in the above step 5 is pulled to complete the cleaning tool 10. Specifically, first, while holding down the lower side of the main body 12 (ring 20 side in FIG. 10), the tip end portion 14a of the strap 14 is pulled downward in the figure (in the direction of arrow e in FIG. 10), and the binding tool 22 The portion fixed by is moved to the vicinity of the ring 20 (see FIG. 11). Next, by further pulling the strap 14 (in the direction of arrow e in FIG. 9), the hole 20b of the ring 20 is passed, and the ring 20 is positioned on the upper end side and the knot of the strap 14 is positioned on the lower end side. At this time, the inner portion 16a and the outer portion 16b of the mesh knit member 16 move in the direction of the arrow g when the strap 14 is pulled.

  When the cleaning tool assembled by the above steps is turned upside down, the cleaning tool 10 according to the present embodiment shown in FIG. 12 is completed. At this time, as shown in the figure, the tip of the knot between the fixing portion 14b of the strap 14 and the binding portion 16d of the main body 12 faces the inside of the main body 12, and is not exposed on the surface of the main body 12. Therefore, the cleaning tool 10 according to the present embodiment causes discomfort to the user due to contact with the body that occurs when the knot tip is exposed on the surface, and the knot tip frays due to use and the main body 12 is damaged. It does not cause a problem such as.

  As described above, according to the cleaning tool 10 of the first embodiment described in detail, the plastic net member 18 having the relatively large through hole 18c is formed in the bellows shape inside the mesh knit member 16 having the fine through hole 16f. With a simple structure of accommodating, it can have moderate elasticity. Therefore, even if the cleaning tool 10 is deformed when it is rubbed against the body, it can be immediately restored to the original substantially spherical shape like a sponge when separated from the body.

  Then, in the process of deforming and restoring the cleaning tool 10 by hand, air passes through the through holes 16f of the mesh knit member 16 and efficiently mixes with the moisture and soap components held in the plastic net member 18. . Thereby, a large amount of fine bubbles are generated, and thus the cleaning tool 10 can quickly foam a large amount of bubbles. In the cleaning tool 10, the inner part 16 a of the mesh-like knit member 16 is open at the end opposite to the strap 14, and a nozzle of a liquid soap bottle (not shown), for example, is inserted from this open end into the mesh. Soap can be supplied into the inner portion 16 a of the knitted member 16. Needless to say, a large amount of soap bubbles can be produced by putting the cleaning tool 10 by hand after putting an appropriate amount of liquid soap into the inner portion 16a of the mesh knit member 16.

  Further, the cleaning tool 10 of the first embodiment has a high elasticity and a shape restoring property because the second net member is accommodated in a space 17 surrounded by the mesh-like knit member 16 in a bellows shape. It has. Therefore, even if the cleaning tool 10 is deformed when being rubbed against the body, the cleaning tool 10 is restored to its original shape as soon as it is separated from the body, and in the process of such deformation / restoration, the first and second net members are restored. Since a large amount of air passes through the stitches, a large amount of fine bubbles can be generated.

  Further, in the cleaning tool 10 of the first embodiment, the plastic net member 18 is covered with the inner cylinder portion 16a so that the inner cylinder portion 16a of the mesh-like knit member 16 is positioned inside the cylinder. . Therefore, even when the cleaning tool 10 is rubbed against the body and deformed into various shapes, there may be a problem that the shape of the cleaning tool is broken due to the plastic net member 18 moving in the net housing space. Absent.

  Further, the main body 12 included in the first embodiment is assembled into a substantially spherical shape so that the mesh net knit member 16 as the outer surface member wraps the plastic net member 18 as the inner net member shrunk in a bellows shape. ing. In the case of a conventional cleaning tool that is assembled into a spherical shape by folding the net multiple times, a hard core is created inside the cleaning tool, making it uncomfortable or difficult to use when rubbed against the body However, in the main body 12 included in the first embodiment, such a core cannot be formed. Therefore, when the body is cleaned using the cleaning tool 10, the touch is good and the body can be used comfortably.

  Further, in the cleaning tool 10 of the first embodiment, the plastic net member 18 is formed in a bellows shape, thereby realizing a shape restoring property and flexibility like a sponge. The bellows-shaped plastic net member 18 can hold a large amount of moisture and bubbles in the inside thereof, and has better drainage than a sponge, and is hygienic by preventing generation of mold and the like.

  Further, the cleaning tool 10 of the first embodiment is assembled so that the bundling portion 16c to which the strap 14 is fixed is passed through the ring 20 together with the strap 14, and the knot tip is directed to the inside of the main body 12. Difficult and excellent in design

  Further, the cleaning tool 10 of the first embodiment is configured to wrap the plastic net member 18 having a relatively large through hole 18c with the mesh knit member 16 having a small through hole 16f. According to such a configuration, in the process of deforming and restoring the main body 12, the foam formed by the plastic net member 18 passes through the mesh-like knit member 16 having a small mesh, and a large amount of finer foam is produced. Can be made.

  In the first embodiment described above, it goes without saying that various modifications are possible. For example, in the first embodiment described above, the strap 14 is used to suspend the cleaning tool 10, but a configuration in which the strap 14 is not used as illustrated in FIG. That is, the cleaning tool 30 as a modified example illustrated in FIG. 13 employs a configuration in which the binding portion 16c of the mesh knit member 16 is bound by a binding tool 31 such as a string. In this case, as shown in FIG. 13, it is optional, but one end portion 18d of the plastic net member 18 is pulled out to the bundling portion 16c of the mesh knit member 16, and the one end portion 18d is bundled with the linear member 31. You may make it do. Further, by providing a string 32 at the folded portion of the mesh-like knit member 16 and making it a drawstring with the string 32, the inner part 16 a can be used as a pocket for storing the solid soap 33. That is, the bar 32 is loosened and the lower end of the inner part 16a is opened, the solid soap 33 is accommodated in the inner part 16a, and then the lower end of the inner part 16a is squeezed by pulling the string 32. The cleaning tool 30 can be used in a state where the solid soap 33 is put.

  Further, in the first embodiment, the bundling portion 16c of the mesh knit member 16 and the strap 14 are fixed by the bundling tool 22, but may be fixed by an adhesive, heat welding, or the like.

  In the cleaning tool 10 of the first embodiment described above, the inner cylinder portion 16a is opened at the portion where the ring member 20 is located. As described above, the bottle 10 containing liquid soap in the inner cylinder portion 16a is opened. A nozzle (not shown) can be inserted to inject liquid soap into the inner cylinder portion 16a. Moreover, you may make it use the inner cylinder part 16a as a pocket which can accommodate solid soap by selecting the diameter in which solid soap can be inserted as a diameter of this inner cylinder part 16a.

  Further, in the first embodiment, the strap 14 is inserted into the inner cylinder portion 16a from the opening portion 16d of the mesh-like knit member 16 (in the direction of arrow d in FIG. 9), but the main body 12 on the opposite side thereof. You may insert from the lower side (ring 20 side of FIG. 9).

  In the first embodiment, as the mesh-like knit member 16 as the outer surface member, a nonwoven fabric, a towel fabric, a gauze fabric, which is a material having a large number of water passage holes, can be selected, and cotton, silk, hemp, As described above, it is preferable to select a material including a natural material such as blended spinning. However, the mesh-like knit member 16 has a multi-layer structure of outer surface members such as two or three layers of selected materials. In this case, when the multilayer structure is used, the outer surface member has a through hole of the plastic net member 18 in which the substantial through hole size of the multilayer structure is the inner net member. It is preferable to set so as to be relatively smaller than the size of 18c. That is, for example, even if the size of the through hole 16f of the mesh knit member 16 is larger than the size of the through hole 18c of the plastic net member 18, the material of the mesh knit member 16 is laminated several times to obtain a multilayer structure. The through-hole 16f of the mesh-shaped knit member 16 can be made substantially small, and the outer surface member can be set to a substantially small through-hole by using this to constitute the outer surface member.

  14 and subsequent drawings show other embodiments of the present invention, and in the description of these embodiments, elements substantially the same as those of the first embodiment described above are denoted by the same reference numerals, The description of the features of each embodiment will be described below with the description omitted.

Second Example (FIGS. 14 to 16) :
14 to 16 show the cleaning tool 40 of the second embodiment. Even in the cleaning tool 40 of the second embodiment, the plastic net member 18 as the inner net member has been described above with reference to FIG. A cylindrical plastic net is used as described above, but after being contracted into a bellows shape to make a donut shape as a whole, a linear member 41 (typically a string is inserted through the inside, that is, the central opening 18d). ). The degree of bundling is arbitrary and does not necessarily need to be tightly bundled. By bundling the plastic net member 18 contracted in a bellows shape with the linear member 41, the bellows-like state can be maintained. In the illustrated example, the plastic net members 18 shrunk in a bellows shape are bundled by the linear members 41 at a plurality of locations separated in the circumferential direction, but only one location may be bundled.

It can preferably be employed.

  Also in the second embodiment, the outer surface member 43 is made of a porous material as in the first embodiment, but the size of the through hole is relatively larger than the size of the through hole 18c of the plastic net member 18. It is better to set it to be smaller. When the outer surface member 43 has a multi-layered structure such as two or three sheets of dough constituting the outer surface member 43, for example, when the outer surface member 43 is formed of a plurality of stacked gauze cloths, It is preferable that the size of the substantial through hole of the gauze fabric having a multilayer structure is set to be smaller than the through hole 18c of the plastic net member 18.

  The cylindrical plastic net member 18 contracted in a bellows shape is maintained in a bellows shape by the linear member 41 as described above, but the linear member 41 has a bound portion as illustrated in FIG. They may be bound with moderate looseness so as to maintain moderate elasticity. Also, as shown in FIG. 15, the linear members 41 are tightly bound so that no elasticity is expected at this bound portion. May be. Further, as illustrated in FIG. 14, the linear member 41 may be bundled by the linear member 41 at a plurality of locations spaced in the circumferential direction of the cylindrical plastic net member 18 contracted in a bellows shape, As shown in FIG. 16, only one portion of the cylindrical plastic net member 18 contracted in a bellows shape may be bundled with a linear member 41.
