  Conventionally, there is a mesh sheet having a mesh formed of synthetic fibers.

  A conventional mesh sheet is a woven fabric obtained by weaving long fibers made of polyester as warp and weft yarns, and is used for filtering and separating particles having a predetermined particle size or more from powders and liquids. (Patent Document 1).

  That is, these mesh sheets can be designed at the weaving stage with the size of the opening surrounded by the warp and weft, unlike the filter material of nonwoven fabric or paper, and the particle size of the particles to be separated by filtration, etc. The filtration performance can be controlled. Therefore, a mesh sheet having a mesh formed of synthetic fibers is useful as a filtration material. Use as a filtering material includes use as a base material for tea bags, for example.

  Moreover, some mesh sheets having a mesh formed of conventional synthetic fibers are used as screen masks for screen printing. That is, it is used for transferring and printing the ink passing through the apertures on the object.

Registered Utility Model No. 3139823

  The inventor of the present invention paid attention to the possibility of using it for cleaning of the oral cavity as one of the new uses of the mesh sheet having the mesh formed by the synthetic fibers described above.

  Under such a problem, an object of the present invention is to provide an oral cleaning tool provided with a mesh sheet having a mesh formed by synthetic fibers.

  The present invention comprises a mesh sheet having a mesh formed of synthetic fibers, and a holding member that holds the mesh sheet, the holding member is gripped and the mesh sheet is guided into the oral cavity, The present invention provides an oral cleaning tool for cleaning dirt in the oral cavity.

  That is, in the mesh sheet of the present invention, a mesh is formed by vertical and horizontal synthetic fibers. This mesh forms a three-dimensional structure having a thickness in the orthogonal direction by overlapping vertical and horizontal synthetic fibers in the direction orthogonal to the surface of the mesh sheet.

  The mesh sheet is held by a holding member, and the holding member is held by the user and guided into the oral cavity. Therefore, the user of the oral cleaning tool can rub a portion such as a tooth, a gum, a tongue, a palate, and an inner cheek in the oral cavity with the mesh sheet by operating the holding member.

  By the way, it is known that stains such as food residue and dental plaque after meals tend to adhere to these intraoral sites, and dirt such as waste products and mold in the oral cavity tend to be exposed. . Therefore, the oral cleaning tool of the present invention makes it possible to clean these stains by rubbing a part in the oral cavity with the mesh sheet having the above three-dimensional structure.

  In addition, since the mesh of the mesh sheet is formed of vertical and horizontal synthetic fibers, the user rinses dirt accumulated on the surface of the mesh by pouring running water or washing water on the surface, and cleans the oral cleaning tool. be able to. By repeating such cleaning and washing, the oral cleaning tool can be used a plurality of times.

  Furthermore, the oral cleaning tool of the present invention can guide the mesh sheet containing the cleaning liquid for oral cleaning into the mouth of the mesh sheet by surface tension.

  The holding member of the present invention may include a U-shaped portion that supports the mesh sheet, and the mesh sheet may be fixed and supported on each side of the U-shaped portion.

  That is, the oral cleaning tool maintains the original shape in a certain range even when a force is applied to the mesh sheet by the mesh sheet being fixed and supported on each side of the U-shaped portion. Can do.

  Specifically, when the oral cleaning tool rubs a site in the oral cavity, a force is applied to the mesh sheet in the surface direction of the mesh sheet by friction with the site, and the mesh sheet is deformed following the unevenness of the site. By doing so, a force is applied in the thickness direction of the mesh sheet. Although the mesh sheet undergoes a certain degree of elastic deformation or elastic deformation and plastic deformation by these forces, the mesh sheet is fixed and supported in three directions by the holding member, so that no major deformation occurs.

  Also, by cleaning the site in the oral cavity while being held by the holding member as described above, the mesh sheet causes elastic deformation and expands and contracts in the surface direction, for example, deforms following the unevenness of the tooth surface, The entire tooth surface including the recess can be rubbed.

  Furthermore, the mesh sheet is deformed following, for example, the unevenness of the tooth surface, and one end edge other than the three sides is not fixed by the holding member and is exposed in the surface direction of the mesh sheet. For this reason, it is possible to rub into the gaps between adjacent teeth that are intricately complicated.

  In addition, since the mesh sheet is supported from the three sides, it is not necessary to support the front and back surfaces. Therefore, it is possible to pour running water or washing water on both surfaces, and cleaning after use can be performed easily.

  The holding member of the present invention may include an annular portion that supports the mesh sheet, and the mesh sheet may be fixed and supported on the entire circumference of the annular portion.

  That is, the oral cleaning tool can maintain the original shape within a certain range even when a force is applied to the mesh sheet, as in the oral cleaning tool provided with the U-shaped portion described above, and used. Subsequent cleaning can be performed easily.

  In addition, since the entire circumference of the annular holding member supports the mesh sheet, the oral cleaning tool is pulled in the surface direction by friction with a site in the oral cavity, whereas the oral cleaning tool is moved up and down by the holding member. The mesh sheet can be supported from the left and right directions. Then, it is easy to apply the surface of the mesh sheet to a flat surface in the oral cavity such as a tongue or an inner cheek and rub the surface in the four directions.

  Moreover, since the mesh sheet is fixed and supported in the four directions by the holding member, both ends of the synthetic fibers in the longitudinal direction and both ends of the synthetic fibers in the lateral direction are fixed to the holding member. . As a result, there is less risk that the mesh sheet will lose its shape. Moreover, since the force applied to the mesh sheet is dispersed in four directions, the possibility that the holding member is deformed is small.

  The holding member of the present invention may include a support portion to which the mesh sheet is attached, and the mesh sheet may be attached to and supported by the support portion.

  That is, since the mesh sheet is affixed to the support part, the mouth cleaning tool is operated by a user to press the support part, whereby the entire surface of the mesh sheet opposite to the affixed side is operated. Is easily applied to a flat surface in the oral cavity, such as the tongue. Therefore, by rubbing the tongue with the oral cleaning tool, it is possible to easily clean the dirt adhering to the surface of the tongue or appearing on the surface of the tongue.

  Further, since the mesh sheet is affixed to the support portion, the initial shape can be maintained within a certain range even when a force due to friction or the like is applied.

  The holding member of the present invention includes a linear shaft portion that supports the mesh sheet, and the mesh sheet is formed into a pleat shape, and in a state of being formed into the pleat shape, The portion may be supported by being fixed to the shaft portion.

  That is, since the mesh sheet is folded into a pleat shape, the mouth cleaning tool can hold the mesh sheet having a large area by the shaft portion. For this reason, the user can guide the mesh sheet having a large area into the oral cavity, and can clean a plurality of scattered stains and spread stains each time the site in the oral cavity is rubbed once. is there. For example, a wide range of parts such as gums, palate, and inner cheek can be efficiently cleaned. Moreover, a larger amount of cleaning liquid for oral cleaning can be included in the mesh sheet.

  The holding member of the present invention may include an elongated spiral portion formed by twisting a wire in a spiral shape, and the mesh sheet may be sandwiched and supported by the wire in the spiral portion.

  That is, the mouth cleaning tool is configured such that the mesh sheet is held along the spiral portion and the spiral portion formed by twisting a wire is easily bent. Therefore, the user can insert the mesh sheet together with the spiral portion into a gap between teeth, for example, and can easily clean the gap.

  The holding member of the present invention may be provided with a sac-like sack part into which fingers can be inserted inside, and the mesh sheet may be attached to and supported by the outer surface of the sack part.

  That is, the oral cleaning tool uses a finger inserted inside the sac part by a user to find a part that needs cleaning in the oral cavity together with the sack part, and operates the finger to apply the part to the mesh sheet. Can be cleaned. Therefore, the tactile sensation of the part in the oral cavity is transmitted to the finger through the sack portion, so that the user can easily find the part that needs cleaning and easily apply the force of the finger applied for cleaning. Can be adjusted.

  Further, when cleaning the oral cavity of another person like an assistant or a guardian of an infant, the user of the oral cleaning tool such as the assistant or the like applies the force of the finger applied to the oral cavity of the other person, It can be easily adjusted according to the tactile sensation.

  Further, since the mesh sheet is affixed to the sack portion, the initial shape can be maintained within a certain range even when a force due to friction or the like is applied.

  The mesh sheet of the present invention may have a mesh woven with synthetic fibers.

  That is, the mesh sheet has a mesh formed by weaving warps and wefts of synthetic fibers. Since the warp yarn and the weft yarn are entangled, even when a force is applied in the surface direction of the mesh sheet due to friction between the mesh sheet and the site in the oral cavity, one side restrains the long movement in the other surface direction. Therefore, the mesh is not easily broken. Thereby, the said oral cleaning tool can maintain the structure of the said mesh | network easily even when rubbing the said part many times, and can maintain the cleaning effect.

  Further, the warp and the weft are alternately exposed on the front side on any surface of the mesh sheet. Therefore, for example, when the mesh sheet rubs a site in the oral cavity in the warp direction, the side surface of the weft can scrape off the site. Further, for example, when the part in the oral cavity is rubbed in the weft direction, the side surface of the warp can wipe off the dirt on the part. As described above, the oral cleaning tool can easily clean dirt regardless of the direction in which the mesh sheet rubs.

  As described above, the present invention provides a mouth cleaning tool that includes a mesh sheet having a mesh formed of synthetic fibers and can be used for a new application.

  A first embodiment of the present invention will be described with reference to FIGS. 1 (a) and 1 (b), 1 is an oral cleaning tool, and this oral cleaning tool 1 has a mesh sheet 4 having a mesh 3 woven by synthetic fibers 2v and 2h shown in FIG. 1 (b) and FIG. And a holding member 5 that holds the mesh sheet 4.

  The oral cleaning tool 1 guides the mesh sheet 4 into the oral cavity M of the user (not shown) while the user holds the holding member 5 with fingers.

  The synthetic fibers 2v and 2h are made of polyethylene terephthalate (PET) as a raw material. As shown in the enlarged view of FIG. 1B and FIG. 2, the monofilament warp 2v long in the weaving direction V of the mesh sheet 4 is perpendicular to the weaving direction V. And a monofilament weft 2h that is long in the weaving width direction H. The warp yarns 2v and the weft yarns 2h are circular in cross section, and each warp yarn 2v and each weft yarn 2h have the same diameter.

  The raw material of the synthetic fibers 2v and 2h is not limited to polyethylene terephthalate, and may be any synthetic resin that can be spun and woven into the mesh sheet 4 and that does not cause health damage in the oral cavity M. Thermoplastic resins such as polyester resins other than terephthalate, polyamide resins such as nylon, and polyolefin resins may be used. Polyester resin contains polylactic acid.

  The warp 2v and the weft 2h are arranged at the same pitches Pv and Ph as viewed from the sheet thickness direction T perpendicular to the surface of the mesh sheet 4. Further, the plurality of warps 2v and the plurality of wefts 2h are entangled so as to form 90 degrees with each other and woven into a plain weave.

  The mesh 3 is one unit in the surface direction constituting the mesh sheet 4, and one mesh 3 is a pair of adjacent warps 2v, 2v in the surface direction of the mesh sheet 4, and a pair of adjacent wefts 2h, 2h. The pair of warps 2v, 2v and the opening 3h surrounded by the pair of wefts 2h, 2h. Accordingly, in the entire mesh sheet 4, the plurality of meshes 3 are continuous in the weaving direction V and the weaving width direction H.

  In the mesh 3, the warp 2 v and the weft 2 h overlap in the sheet thickness direction T, so that a three-dimensional structure in the sheet thickness direction T is formed for one mesh 3 a.

  That is, each warp 2v and each weft 2h is inclined closer to the sheet thickness direction T with respect to the weaving direction V and the weaving width direction H, respectively. Therefore, in the first corner 6a located at the upper left corner of the rectangular imaginary line representing the mesh 3a as shown in FIG. 2, the weft thread 2h passes the front side to the left and right and the warp thread 2v passes the back side up and down. In the second corner 6b located at the upper right corner, the warp 2v passes up and down the front side and the weft 2h passes through the back side to the left and right. Similarly, at the third corner 6c located at the lower right corner and the fourth corner 6d located at the lower left corner, the warp yarn 2v and the weft yarn 2h pass in the same manner as the first corner 6a and the second corner 6b, respectively. .

  Thus, the mesh 3 has a three-dimensional structure formed by the entanglement of the warp 2v and the weft 2h. Such meshes 3 are continuously arranged on the mesh sheet 4. Therefore, the mesh sheet 4 has a three-dimensional structure over the entire surface.

  In each mesh 3, the warp 2v and the weft 2h are arranged at the same pitches Pv and Ph, and each warp 2v and each weft 2h have the same diameter. Therefore, the three-dimensional structure of the mesh sheet 4 is a structure in which the same or inverted three-dimensional structure as that of one mesh 3a is repeated on the entire surface.

  Further, each mesh 3 is surrounded by the warp 2v and the weft 2h, and has an opening 3h that penetrates the mesh sheet 4 in the sheet thickness direction T. Therefore, the mesh sheet 4 has a porous structure in which the openings 3h are uniformly distributed over the entire surface.

  The mesh sheet 4 is arranged at the center in the thickness direction of the holding member 5 in the head portion 5abc of the holding member 5 formed in a U-shape as shown in the plan view of FIG. Like the front view which b) represents, it arrange | positions in the position enclosed by the U-shaped three sides by the front-end | tip part 5a of the head 5abc, the back part 5b, and the base end part 5c. Further, the mesh sheet 4 is arranged with respect to the holding member 5 so that the weaving direction V coincides with the vertical direction of FIG.

  The holding member 5 is a molded product of a thermoplastic resin such as polypropylene, polystyrene, polyethylene, polyethylene terephthalate, etc., and has a head portion 5abc and a grip portion extending linearly in the longitudinal direction of the holding member 5 from the base end portion 5c of the head portion 5abc. 5d. In the head 5abc, the mesh sheet 4 is held from above and below in FIG. 1 (a) in a U-shape as shown in FIG. 1 (b). The holding member 5 fixes at least one end and the other end of the mesh sheet 4. Further, the user operates the entire oral cleaning tool 1 by grasping the grip portion 5d with fingers.

  The holding member 5 is formed by insert molding together with the mesh sheet 4. For example, a mesh sheet material having a size obtained by adding a pinch allowance corresponding to the U-shaped three sides to the size of the mesh sheet 4 exposed after molding is inserted into an injection mold in advance. A resin is injected around and molded integrally. Further, for example, after forming together with the belt-shaped mesh sheet material, it may be cut along the outer edge of the holding member 5 from the belt-shaped mesh sheet material.

  As described above, after forming, the pinching margin is pinched inside the holding member 5, and the mesh sheet 4 is fixed to the holding member 5. At this time, the raw material of the mesh sheet 4 and the raw material of the holding member 5 may be the same type of thermoplastic resin, and in that case, they are easily integrated.

  The mesh sheet 4 is fixed to the front end portion 5a, the back portion 5b, and the base end portion 5c by insert molding. That is, as shown in FIG. 1B, the mesh sheet 4 has a boundary between the first straight portion 4a that is a boundary with the distal end portion 5a, a curved portion 4b that is a boundary with the back portion 5b, and a base end portion 5c. The second linear portion 4c is fixed and supported by the holding member 5. The first straight portion 4a, the curved portion 4b, and the second straight portion 4c of the mesh sheet 4 continuously form one boundary line portion 4abc with the holding member 5.

  That is, the mesh sheet 4 is supported by the boundary member 4abc in the three directions being fixed by the holding member even when receiving a force in the surface direction or the sheet thickness direction T due to friction with a site in the oral cavity M or the like. . Therefore, although the mesh sheet 4 undergoes a certain degree of elastic deformation, or elastic deformation and plastic deformation, it does not cause a large loss of shape.

  On the other hand, the third straight portion 4 e that is the opposite side of the curved portion 4 b of the mesh sheet 4 is not fixed by the holding member 5. Therefore, for example, when the mesh sheet 4 is inserted between teeth in the oral cavity M, the user can enter the mesh sheet 4 from the third straight portion 4e.

  The head 5abc is small enough to be inserted into the oral cavity M from the user's lips, and small enough to move the mesh sheet 4 up, down, left, and right within the oral cavity M of the user. The grip portion 5d has a thickness that allows the user to grip it with fingers.

  With these configurations, the user can grasp the grip portion 5d with fingers and insert the mesh sheet 4 into the oral cavity M. Further, after the insertion, the user moves the holding member 5 in the surface direction of the mesh sheet 4 so that the mesh sheet 4 is applied to each part of the mouth M such as teeth, gums, interdental teeth, tongue, palate, inner cheek and the like. In such a state, the surface of each part can be rubbed with one or both surfaces of the mesh sheet 4.

  Referring to FIG. 3, by rubbing the surface of a part in the oral cavity M such as teeth and gums with the mesh sheet 4, dirt S (not shown) such as a postprandial meal and plaque adhering to the surface of each part. Explain how this can be cleaned.

  Since the mesh sheet 4 has a three-dimensional structure formed by the entanglement of the warp yarn 2v and the weft yarn 2h over the entire surface, the stain S can be scraped off by the warp yarn 2v and the weft yarn 2h, and the scraped stain S can be removed by warping. It can be deposited on the 2v surface, the weft 2h surface, or the warp 2v surface and the weft 2h surface.

  As shown in FIG. 3, in one mesh 3a, the mesh sheet 4 has a first weft 2h (i) that passes through the front side in the sheet thickness direction T at the first corner 6a and faces downward. The side surface 7ac is exposed on the front side of the figure. Further, the second warp 2v (ii) passing up and down the sheet corner in the sheet thickness direction T at the second corner 6b has a side surface 7ab facing leftward exposed on the near side in the drawing. Similarly, the second weft yarn 2h (ii) and the first warp yarn 2v (i) passing through the front side in the sheet thickness direction T at the third corner 6c and the fourth corner 6d, respectively, left and right, respectively, A side surface 7bc facing upward and a side surface 7cd facing right are exposed on the front side of the figure.

  The warps 2v (i) and 2v (ii) are arranged at the same pitch Pv, the wefts 2h (i) and 2h (ii) are arranged at the same pitch Ph, and the warps 2v (i) and 2v (ii) Since the wefts 2h (i) and 2h (ii) are orthogonal to each other, the mesh 3a is formed in a rectangle with the first to fourth corners 6a, 6b, 6c and 6d as vertices.

  As for each side surface 7ab, 7bc, 7cd, 7ac, the user can scrape adhering dirt S in the surface direction of the mesh sheet 4 by rubbing each part in the oral cavity M with the mesh sheet 4. Further, the scraped dirt S is deposited on the surfaces of the side surfaces 7ab, 7bc, 7cd, and 7ac.

  The same applies to the case where the mesh sheet 4 is viewed from the back side in the sheet thickness direction T.

  After the dirt S is deposited on the surfaces of the side surfaces 7ab, 7bc, 7cd, 7ac, the user pours running water, washing water, etc. on the surface of the mesh sheet 4 on the side where the site in the oral cavity M has been rubbed and rubs it. Thus, the dirt S can be removed from the mesh 3 and the oral cleaning tool 1 can be washed. That is, since the side surfaces 7ab, 7bc, 7cd, and 7ac from which the dirt S has been scraped are exposed to the front side, the dirt S can be washed away with running water, washing water, or the like from the same side.

  In addition, even when the dirt S accumulates in the opening 3h and causes clogging, the user can wash away the dirt S in the opening 3h by pouring running water, washing water, etc. from the surface of the mesh sheet 4. It can be removed from the mesh 3.

  As described above, the dirt S is scraped off by the side surfaces 7ab, 7bc, 7cd, and 7ac of the mesh 3a, and the dirt S is deposited on the surfaces of the side surfaces 7ab, 7bc, 7cd, and 7ac. Dirt S can be cleaned. That is, the user prepares the oral cleaning tool 1 including the mesh sheet 4 having the mesh 3 woven by the synthetic fibers 2v and 2h and the holding member 5 that holds the mesh sheet 4, and holds the holding member 5 The mesh sheet 4 can be guided into the oral cavity M, and the dirt S in the oral cavity M can be cleaned by the mesh sheet 4. Moreover, the user can remove the dirt S from the mesh 3 by pouring running water, washing water or the like onto the surface of the mesh sheet 4 and wash the used oral cleaning tool 1.

  Furthermore, the user can clean the dirt S in the oral cavity M again with the cleaned oral cavity cleaning tool 1. Thus, the user can use the oral cleaning tool 1 a plurality of times by repeating the cleaning of the dirt S and the removal of the dirt S.

  In FIG. 1B, the mesh sheet 4 is arranged so that the weaving direction V and the vertical direction of the holding member 5 coincide. However, the arrangement direction of the mesh sheet 4 is not limited to this direction. That is, the mesh sheet 4 may be arranged such that the weaving width direction H coincides with the short direction, and the weaving direction V is 30 degrees, 45 degrees, 60 degrees with respect to the longitudinal direction. It may be arranged at any angle.

  Even if the warp yarns 2v and the weft yarns 2h are not the same diameter, the warp yarns 2v and the weft yarns 2h may have different diameters if the warp yarns 2v have the same diameter and the warp yarns 2h have the same diameter. .

  Further, the cross section of the warp 2v, the weft 2h, or the warp 2v and the weft 2h does not have to be a circular cross section, and may be an irregular cross section, a square cross section, or the like.

  Further, the woven fabric structure of the warp 2v and the weft 2h may be a twill weave other than plain weave, satin weave, or the like. The mesh sheet 4 may have another configuration as long as it has a mesh 3 formed by the synthetic fibers 2v and 2h.

  FIG. 4 shows a modification of the mesh sheet 4 in the present embodiment. FIG. 4 is a photomicrograph of product number 4817 of a mesh filter “Tea Road Sharp” (“Tea Road” is a registered trademark) manufactured by Yamanaka Sangyo Co., Ltd. In FIG. 4, 8a, 8b, 8c, and 8d are thermal welding points located at the first to fourth corners 6a, 6b, 6c, and 6d of the mesh 3a, and the meshes at the respective thermal welding points 8a, 8b, 8c, and 8d. The warp yarns 2v (i), 2v (ii) and the weft yarns 2h (i), 2h (ii) constituting 3a are heat-welded with each other in the mesh sheet 4 overlapping in the sheet thickness direction T. Other configurations are the same as those in the embodiment shown in FIGS.

  Thus, since the warp 2v and the weft 2h are thermally welded, when the mesh sheet 4 rubs the surface of the site in the oral cavity M, the mesh 3 has a biased frictional force in the surface direction of the mesh sheet 4. Even when they occur, it is unlikely that there will be variations in the spacing between adjacent warp yarns 2v and variations in the spacing between each weft yarn 2h.

  That is, when the friction between the part of the mesh 3a and the part in the oral cavity M is large, a large force in the surface direction of the mesh sheet 4 is applied to the part of the mesh 3a. Even in this case, since the warp yarns 2v (i), 2v (ii) and the weft yarns 2h (i), 2h (ii) are fixed at the heat welding points 8a, 8b, 8c, 8d, only the specific mesh 3a is used. However, it does not spread farther than other meshes 3.

  Therefore, in this modification, even when there is a difference in the magnitude of friction generated between the mesh sheet 4 and the site in the oral cavity M, the variation in the size of each mesh 3 is constant. By restraining within the range, it becomes easy to keep the degree of the cleaning effect of the dirt S of the entire mesh sheet 4 uniform.

  In this modification, the warp yarns 2v and the weft yarns 2h are thermally welded to each other in the sheet thickness direction T of the mesh sheet 4, so that the warp yarns 2v or the weft yarns 2h are in a position where they are biased by one use. Less likely to slip. For this reason, the warp yarn 2v and the weft yarn 2h are easily kept at the first position even after the second and subsequent use, and it is easy to increase the number of possible uses until disposal.

  A part of the weft 2h in this example may include not only a monofilament but also a multifilament obtained by twisting a plurality of single fibers. However, when some of the weft yarns 2h are multifilaments, these are only entangled with the warp yarns 2v, and these are not welded to the warp yarns 2v.

  In this way, by including a multifilament with a high density of fibers in a part of the weft 2h, the user can more efficiently remove the dirt S when rubbing the part in the oral cavity M in the weaving direction V with the mesh sheet 4. Can be scraped off.

  The photographs in FIGS. 5A and 5B are photographs before and after cleaning the pseudo plaque Sa applied to the interdental portion of the first tooth mold T1 using the oral cleaning tool 1 shown in the photograph in FIG. . FIG. 5 (a) shows a state where a pseudo plaque Sa imitating the dirt S is applied to the first tooth mold T1, and FIG. 5 (b) shows the first tooth mold T1 shown in the photograph of FIG. The state after rubbing with the tool 1 is shown.

  In an actual usage pattern, a second tooth mold T2 (not shown) is often arranged adjacent to the first tooth mold T1 with a gap G interposed therebetween. In such a case, the user holds the holding portion 5d of the holding member 5 and moves the third straight portion 4e of the mesh sheet 4 shown in FIG. 1B to the first tooth mold T1 and the second tooth. The gap G is applied from the tooth tip side with the mold T2. Then, the mesh sheet 4 is caused to enter the gap G with the operation of pushing down the holding member 5 toward the tooth base.

  Then, the user moves the mesh sheet 4 so that the third straight portion 4e moves up and down between the tooth tip side and the tooth base side, so that the user can move the mesh sheet 4 on the gap G side of the first tooth mold T1. The surface can be rubbed with one surface of the mesh sheet 4. Further, when the second tooth mold T <b> 2 is arranged, the surface on the gap G side of the second tooth mold T <b> 2 can be rubbed with the other surface of the mesh sheet 4.

  At this time, the one surface of the mesh sheet 4 is the side surface 7ac of the first weft thread 2h (i) shown in FIG. 3 or the second weft thread 2h when the oral cleaning tool 1 is moved toward the tooth base side. Of the side surface 7bc of (ii), the first tooth mold T1 is rubbed by one side surface 7ac, 7bc facing the tooth base side. On the contrary, when moved toward the tooth tip side, the first tooth mold T1 is rubbed by the other side surfaces 7bc, 7ac facing the tooth tip side.

  Further, the user moves the mesh sheet 4 so as to move back and forth between the lingual side and the lip side so that the surface on the gap G side of the first tooth mold T <b> 1 is the one surface of the mesh sheet 4. The surface on the gap G side of the second tooth mold T2 can be rubbed with the other surface of the mesh sheet 4.

  At this time, when the oral cleaning tool 1 is moved toward the lingual side, the one surface of the mesh sheet 4 is the side surface 7cd of the first warp 2v (i) or the second warp 2v ( Of the side surface 7ab of ii), the first tooth mold T1 is rubbed by one side surface 7cd, 7ab facing the lingual side. On the contrary, when moved toward the lip side, the first tooth mold T1 is rubbed by the other side surfaces 7ab and 7cd facing the lip side.

  FIG. 7A is a photograph before the mesh sheet 4 rubs the first tooth mold T1. FIG. 7B is a photograph after the mesh sheet 4 is moved upward and rubbed against the first tooth mold T1. Further, FIG. 7C is a photograph after the mesh sheet 4 is moved to the right in the figure and rubbed. 7 (b) and 7 (c), a state in which pseudo plaques Sa imitating the dirt S are accumulated is shown.

  7A, 7B, and 7C are monofilament warp yarns 2v and monofilament weft yarns 2h that are thermally welded to each other in the sheet thickness direction T. The wefts 2h and 2h (mu) include multifilament wefts 2h (mu).

  As described above, the user moves the mesh sheet 4 up and down between the tooth tip side and the tooth base side, and moves back and forth between the tongue side and the lip side, or between the tooth tip side and the tooth base side. The first tooth mold T1 can be rubbed by simultaneously reciprocating both between the tongue and the lip side.

  The first tooth mold T has irregularities on the peripheral surface including the surface on the gap G side. On the other hand, the mesh sheet 4 is fixed to and supported by the holding member 5 at the boundary portion 4abc. Therefore, since the mesh sheet 4 is elastically deformed and expands and contracts in the surface direction, and follows these irregularities, the circumferential surface of the first tooth mold T1 including the concave portions can be rubbed. Thereby, the oral cavity cleaning tool 1 can clean the pseudo plaque Sa imitating the dirt S adhering to the peripheral surface of the tooth mold T1 including the first recess.

  As described above, the user can simulate the pseudo plaque Sa imitating the dirt S attached to the first tooth mold 1 by the oral cleaning tool 1 including the mesh sheet 4 as shown in the photograph after cleaning shown in FIG. Can be cleaned.

  FIG. 8 illustrates a second embodiment of the present invention. In FIG. 8, 11 is an oral cleaning tool, and this oral cleaning tool 11 includes a mesh sheet 14 having a mesh 13 woven by synthetic fibers 12v and 12h, and a holding member 15 that holds the mesh sheet 14.

  As shown in the front view of FIG. 8, the mesh sheet 14 is arranged on the inner side in the radial direction of the head frame 15 a of the holding member 15 formed in an elliptical ring shape. That is, both the front and back surfaces of the mesh sheet 14 are not covered by the holding member 15, and the mesh 13 is exposed facing both the front side and the back side in FIG. 8.

  The mesh sheet material is integrated with the holding member 15 by insert molding, and the inner diameter of the mesh sheet material is exposed from the inner periphery of the head frame 15a, so that the periphery is surrounded by the boundary line portion 14a with the head frame 15a. The mesh sheet 14 is formed. Further, the mesh sheet 14 is arranged with respect to the holding member 15 so that the weaving direction V coincides with the vertical direction of FIG.

  The synthetic fibers 12v and 12h forming the mesh 13 of the mesh sheet 14 include a plurality of warp yarns 12v and a plurality of weft yarns 12h. Further, since the boundary line portion 14a between the mesh sheet 14 and the holding member 15 covers the entire circumference of the mesh sheet 14, both ends of all the warp yarns 12v and both ends of all the weft yarns 12h are fixed to the head frame 15a. .

  The holding member 15 includes a head frame 15a and a grip portion 15b extending linearly from one end of the head frame 15a in the long axis direction of the head frame 15a. The user operates the entire oral cleaning tool 11 by grasping the grip portion 15b with fingers. Other configurations are the same as those in the first embodiment.

  Thus, the mesh sheet 14 is supported from both sides in the weaving direction V and both sides in the weaving width direction H. Therefore, the mesh sheet 14 is pulled in the surface direction by friction with a part in the oral cavity M such as the tongue and the inner cheek, whereas the holding member 15 pulls the mesh sheet 14 from the upper, lower, left, and right directions in the front view. Because of the support, the force is dispersed and there is little risk of deformation in either direction. Further, there is little possibility that the holding member 15 is deformed.

  Further, since the head frame 15a of the holding member 15 has an elliptical ring shape and the mesh sheet 14 is supported from the four directions, the user moves the mesh sheet 14 in an arbitrary surface direction in the oral cavity M. Thus, it is possible to easily clean a flat surface such as a tongue or inner cheek.

  Furthermore, since both the front and back surfaces of the mesh sheet 14 are exposed, the user removes the dirt S from the mesh 13 by pouring running water, washing water, etc. from both the front and back surfaces, and easily irrigating the oral cavity. The cleaning tool 11 can be washed.

  In addition, the mesh sheet 14 and the holding member 15 can be easily moved in the arbitrary surface direction in the oral cavity M by the user other than the elliptical shape and the elliptical ring shape having the long axis in the longitudinal direction of the holding member 14, respectively. If possible, it may be formed in an annular shape or an annular shape, an elliptical shape having a major axis in a direction different from the longitudinal direction, an elliptical ring shape, or the like.

  9A and 9B illustrate a third embodiment of the present invention. 9 (a) and 9 (b), 21 is a mouth cleaning tool, and the mouth cleaning tool 21 has a mesh sheet 24 having a mesh 23 woven by synthetic fibers 2v and 2h, and a holding member for holding the mesh sheet 24. 25. The synthetic fibers 22v and 22h forming the mesh 23 of the mesh sheet 24 include a plurality of warps 22v and a plurality of wefts 22h.

  As shown in the front view of FIG. 9A, the mesh sheet 24 is supported by being attached to the head portion 25a of the holding member 25 that is long from side to side by thermal welding from below. At this time, in FIG. 9A, the mesh sheet 24 is arranged so that the front surface 24f faces downward and the back surface 24b faces upward. That is, the mesh sheet 24 has the back surface 24b fixed to the head portion 25a of the holding member 25 by heat welding.

  Further, the mesh sheet 24 is arranged with respect to the holding member 25 so that the weaving direction V coincides with the vertical direction of FIG.

  In the mesh 23 of the mesh sheet 24, both the warp yarn 22v and the weft yarn 22h are exposed on the back surface 24b side. Therefore, the mesh sheet 24 is affixed to the head 25a by heat-welding both the warp 22v and the weft 22h to the lower surface of the head 25a of the holding member 25.

  The holding member 25 has a head portion 25a, a neck portion 25b that is continuous with the head portion 25a, and a grip portion 25c that is continuous with the neck portion 25b and that is long on the left and right. The neck portion 25b is inclined downward with respect to the longitudinal direction of the grip portion 25c so that the surface direction of the mesh sheet 24 forms an angle θa downward with respect to the longitudinal direction of the grip portion 25c in a front view. Other configurations are the same as those in the first embodiment.

  The user grasps the grasping portion 25c of the holding member 25 and guides the mesh sheet 24 into the oral cavity M so that the surface 24f of the mesh sheet 24 comes into contact with a surface such as a tongue. Then, the user operates the mesh sheet 24 so that it moves back and forth between the back side and the tip side of the tongue, moves right and left of the user left and right, or moves in an oblique direction, and the tongue 24 is moved by the surface 24f. Rub the surface.

  At this time, the user operates the head 25a of the holding member 25 so as to push the mesh sheet 24 from the back surface 24b toward the front surface 24f, so that the entire surface 24f is flat in the oral cavity M like a tongue. Can be applied to any surface.

  Further, when the oral cleaning tool 21 is moved toward the back side of the tongue, the surface 24f of the mesh sheet 24 is the side surface 7cd of the first warp 2v (i) or the second warp 2v (ii) shown in FIG. Of the side surface 7ab, the surface of the tongue is rubbed by one side surface 7cd, 7ab facing the back side. On the contrary, when it is moved toward the tip side, the surface of the tongue is rubbed by the other side surfaces 7ab and 7cd facing the tip side.

  When the oral cleaning tool 21 is moved toward the left side of the user, the surface 24f of the mesh sheet 24 is the side surface 7ac of the first weft thread 2h (i) or the side surface of the second weft thread 2h (ii) shown in FIG. The surface of the tongue is rubbed by one side face 7ac, 7bc facing the left side of 7bc. On the contrary, when it is moved toward the right side, the surface of the tongue is rubbed by the other side surfaces 7bc and 7ac facing the right side.

  Accordingly, the user can efficiently clean the tongue both in the case where the oral cleaning tool 21 is moved back and forth and in the case where it is moved left and right.

  Furthermore, the mouth cleaning tool 21 applies a uniform pressure in the surface direction to the surface of the tongue because the mesh 23 composed of the warp yarns 22v and the weft yarns 22h each having a small surface area rubs the surface of the tongue. be able to. Therefore, the risk of damaging the surface of the tongue is small depending on the oral cleaning tool 21.

  In the mesh sheet 24, since both the warp yarns 22v and the weft yarns 22h are thermally welded to the holding member 25, the surface direction of the lower surface of the head 25a with respect to the holding member 25 even when a force due to friction or the like is applied. The possibility of displacement is small. Thereby, the oral cleaning tool 21 has little possibility that the mesh | network 23 will deform | transform after use, and can maintain an original shape easily.

  The mesh sheet 24 may be affixed with an adhesive in addition to being affixed to the holding member 25 by thermal welding.

  10 and 11 illustrate a fourth embodiment of the present invention. In FIG. 10, 31 is an oral cleaning tool, and this oral cleaning tool 31 includes a mesh sheet 34 having a mesh 33 woven by synthetic fibers 32v and 32h, and a holding member 35 that holds the mesh sheet 34.

  The oral cleaning tool 31 has a central axis C that extends to the left and right in FIG. FIG. 11 is a cross-sectional view of the oral cleaning tool 31 taken along the line AA, showing the cross section taken along the line AA shown in FIG. As shown in FIG. 11, the mesh sheet 34 is folded so that one sheet body alternately repeats a folded portion 34 a and a folded portion 34 b of a valley fold, and the ridge lines of the folded portions 34 a and 34 b. It is formed by being formed into a cylindrical pleat shape in which the direction coincides with the axial direction of the central axis C, and the folded portion 34a of each mountain fold is positioned radially outward from the folded portion 34b of each valley fold. The

  As shown in FIG. 11, the mesh sheet 34 is arranged in a radial pattern around the central axis C. There are eight mountain-folded folded portions 34a and valley-folded folded portions 34b, respectively. Eight mountain-folded folded portions 34a are arranged at equal intervals, and both are arranged at a distance of r1 from the central axis C. In addition, eight valley folding portions 34b are arranged at equal intervals, and all are arranged at a distance of r2 from the central axis C.

  The mesh sheet 34 includes a region 34c facing the clockwise direction CL centered on the central axis C and a region 34d facing the counterclockwise direction UC centered on the central axis C in the cross-sectional view taken along the line AA. Both have a mesh 33.

  As shown in FIG. 10, the holding member 35 has a linear shaft portion 35a to which the mesh sheet 34 is fixed, and a grip portion 35b that is linearly connected to the shaft portion 35a. In the holding member 35, the shaft portion 35a has a substantially regular octagonal cross section, and the grip portion 35b has a square cross section.

  As shown in FIG. 11, the shaft portion 35a is constituted by a bundle of 16 linear members 35c. That is, each linear member 35c is arranged so as to draw a substantially regular octagon centered on the central axis C, and projects leftward from the end face of the gripping portion 35b.

  In the mesh sheet 34, the folded portion 34b of the valley fold turns around the central axis C side from one of the clockwise direction CL side and the counterclockwise direction UC side of the linear member 35c, and the clockwise direction CL side and It winds to the other of the counterclockwise directions UC side. Further, the mesh sheet 34 is wound around every other linear member 35c one after another in the clockwise direction CL or counterclockwise direction UC while forming the mountain-folded folded portion 34a in a bowl shape, and around the central axis C. During one round, eight mountain-folded folded portions 34a and eight valley-folded folded portions 34b are formed.

  At this time, the mesh sheet 34 is held by the holding member 35 by being sandwiched and fixed between adjacent linear members 35c. Other configurations are the same as those in the first embodiment.

  The user guides the mesh sheet 34 into the oral cavity M and cleans the dirt S in the oral cavity M by holding the grip 35b of the holding member 35 with fingers and operating the oral cleaning tool 31.

  At this time, since the mesh sheet 34 has the mesh 33 in both the region 34c facing the clockwise direction CL of the eight surfaces and the region 34d facing the counterclockwise direction UC of the eight surfaces, the oral cleaning tool 31 is used for cleaning. A mesh sheet 34 having a wide effective area can be provided.

  Therefore, even when cleaning a wide area in the oral cavity M such as the gums, palate, and inner cheek, for example, the user removes a plurality of dirt S scattered in these parts and the dirt S that spreads and adheres. The oral cavity cleaning tool 31 can be efficiently cleaned.

  In addition, since there is a gap between the back surface of each region 34c facing the clockwise direction CL and the back surface of the region 34d facing the counterclockwise direction UC around the central axis C, the user can By pouring running water, washing water, etc. from the front and back of 34c, 34d and rinsing, the dirt S can be removed from the mesh 33, and the oral cleaning tool 31 can be easily washed.

  Furthermore, a user cleans each site | part in the oral cavity M, for example after making the oral cavity cleaning tool 31 after washing | cleaning contain the washing | cleaning liquid for oral cavity cleaning by the method of spraying, application | coating, soaking, etc. Can do. At this time, the cleaning liquid for oral cleaning is held in the mesh 33 of the mesh sheet 34 and guided into the oral cavity M together with the mesh sheet 34. After the induction into the oral cavity M, the cleaning liquid for cleaning the oral cavity flows out of the mesh 33 due to deformation such as the pleat shape being crushed, thereby exerting an action such as enhancing the cleaning effect of each part in the oral cavity M.

  Since the oral cleaning tool 31 of the present embodiment includes the mesh sheet 34 having a wide effective area, a larger amount of the cleaning liquid for oral cleaning can be held in the mesh 33.

  Note that the number of fold-back portions 34a and the number of valley-fold fold portions 34b of the mesh sheet 34 are not limited to eight, and the user can sufficiently clean the dirt S in the oral cavity M. If it exists, it may be in the range of 3 to 20 locations. The distances from the central axis C are not necessarily r1, and the distance from the central axis C is different for each mountain folding part 34a as long as it is arranged in a pleat shape. May be. Similarly, the distances from the central axis C of the valley folded portions 34b may not be r2, and may be different for each valley folded portion 34b.

  Further, the mesh sheet 34 may be wound not only on every other one of the linear members 35c but also at a pitch of two or more. Furthermore, it is not limited to the one that is sandwiched and fixed between the adjacent linear members 35c, and if it is firmly held by the holding member 35, for example, instead of the linear member 35c, an orange cross section is provided by a plurality of slits. The mesh sheet 34 may be fixed by sandwiching the folded-back part 34b of the valley fold between the split slits of the shaft part.

  Further, the mesh sheet 34 is not limited to one obtained by bending a single sheet body, and may be configured by connecting a plurality of, for example, strip-shaped sheet pieces.

  The washing of the mesh sheet 34 is not limited to washing with running water or washing water, and may be washing using ultrasonic waves or a combination of ultrasonic waves and running water.

  12-14 illustrate a fifth embodiment of the present invention. 12, 41 is an oral cleaning tool, and this oral cleaning tool 41 holds a mesh sheet 44 having a mesh 43 woven by synthetic fibers 42v and 42h shown in FIG. 13, and a mesh sheet 44 shown in FIG. Holding member 45 to be provided. The holding member 45 includes a wire portion 45a and a grip portion 45b.

  The mesh sheet 44 is formed into an isosceles trapezoidal shape as shown in FIG. 13 after weaving, and a plurality of cuts 9 parallel to the upper and lower bases are made from both leg sides toward the center line Cm. Has been. The notch 9 is longer as it is closer to the lower base according to the inclination of the isosceles trapezoidal leg. Further, the mesh sheet 44 is temporarily fastened to a wire portion 45a arranged so that a portion close to the center line Cm extends in the left-right direction at the center in the up-down direction in FIG.

  The wire portion 45a is composed of a single straight metal wire. The metal wire is arranged with its center folded back 180 ° on the upper base side of the isosceles trapezoid so that both ends overlap on the lower base side of the isosceles trapezoid. The folded metal wire sandwiches the mesh sheet 44 in the sheet thickness direction T.

  The mesh sheet 44 is disposed so that the weaving width direction H coincides with the direction of the center line Cm.

  Then, when the wire portion 45a is twisted a plurality of times around the center line Cm, the mesh sheet 44 has a screw shape as shown in FIG. 14 while the portion close to the center line Cm is sandwiched between the wire portions 45a. Molded. As a result, the mesh sheet 44 is fixed to the wire portion 45a. At this time, the wire portion 45a forms an elongated spiral shape by being twisted a plurality of times.

  In addition, since the screw-shaped mesh sheet 44 is preliminarily provided with the notches 9, the blades projecting in the radially outward direction without the outer portion in the radial direction from the deepest portion of the notches 9 being sandwiched between the wire portions 45a. The part 44a will be formed. Further, since the slit 9 closer to the lower bottom is longer, the blade portion 44a is longer in the radial direction toward the right side in FIG. As a result, the mesh sheet 44 is formed in a shape close to a truncated cone as shown by the phantom line in FIG.

  The gripping part 45b is a molded product of a thermoplastic resin such as polypropylene, polystyrene, polyethylene, polyethylene terephthalate, etc., and continues to the right side of the wire part 45a in FIG. The grip portion 45b is formed by insert molding together with the wire portion 45a. That is, resin is injected around the right end portion of the wire portion 45a, and is molded integrally with the end portion in an injection mold. Other configurations are the same as those in the first embodiment.

  The user guides the mesh sheet 44 fixed around the wire portion 45a into the oral cavity M by grasping the grip 45b of the holding member 45 with fingers and operating the oral cleaning tool 41, The dirt S is cleaned.

  At this time, the user can bend the wire portion 45a with fingers in advance and deform the oral cleaning tool 41 into a shape that can be easily inserted into a region such as between teeth. Thereby, it is possible for the user to insert the oral cleaning tool 41 into the intricate gap between the teeth, or to insert between the teeth from the inside to the outside of the mouth M, and In the inserted state, the mesh sheet 44 can be reciprocated in the direction of the central axis Cm.

  Further, for example, even when the gap between the teeth is narrow, the mesh sheet 44 is formed in a shape close to a truncated cone as described above. It is easy to aim and can be easily inserted from the top side of the shape close to the truncated cone.

  The mesh sheet 44 has a plurality of meshes 43, and both the warp yarns 42 v and the weft yarns 42 h form the meshes 43. Therefore, for example, when the gap between the teeth is reciprocated in the direction of the central axis Cm, the mesh sheet 44 has both the side surfaces 7ab and 7cd of the warp yarn 2v and the side surfaces 7bc and 7ac of the weft yarn 2h shown in FIG. Can scrape the dirt S on the tooth surface. Therefore, the oral cleaning tool 41 can efficiently clean the tooth surface regardless of the direction in which the mesh sheet 44 rubs against the dirt S.

  The number of mesh sheets 44 sandwiched between the wire portions 45a is not limited to one, and may be two or more as long as the mesh sheets 44 can be twisted together with the wire portions 45a. Further, the shape is not limited to an isosceles trapezoid, and any shape that can be formed into a shape that can be inserted into the gap between the teeth after being sandwiched between the wires 45a is rectangular or two sides in the direction of the center line Cm. A barrel-shaped quadrilateral deformed so as to be bent in a direction away from the center line Cm may be used.

  Furthermore, the mesh sheet 44 and the wire portion 45a may be fixed by an adhesive or the like before being twisted, instead of being temporarily fastened before being twisted together.

  The wire portion 45a and the grip portion 45b are not only integrated by insert molding, but may be assembled by inserting a part of the wire portion 45a into a hole previously opened in the grip portion 45b. The grip portion 45b may be divided into two parts and assembled so as to sandwich the part.

  The wire portion 45a does not need to be a metal wire, and may be a wire made of another material such as resin as long as the mesh sheet 44 can be pinched by being twisted. For example, “Techno Roto” (registered trademark) which is a plastic wire manufactured by Mitsui Chemicals, Inc. can be used for the wire portion 45a. This “Techno Roto” is excellent in plastic deformability and shape retention after deformation, so that the mesh sheet 44 can be sandwiched and twisted, and the return amount with respect to torsion is small. 44 can be fixed. Moreover, since there is little risk of damaging teeth and gums, it is suitable for the wire portion 45a.

  FIG. 15 illustrates a sixth embodiment of the present invention. In FIG. 15, 51 is an oral cleaning tool, and the oral cleaning tool 51 includes a mesh sheet 54 having a mesh 53 woven by synthetic fibers 52 v and 52 h, and a holding member 55 that holds the mesh sheet 54.

The user can put the oral cleaning tool 51 by inserting one finger F into the inside of the sack portion 55a from the opening 55b. In addition, the finger F wearing the oral cleaning tool 51 is allowed to enter the oral cavity M, and the finger F can be moved so that the sack portion 55a can touch the site in the oral cavity M.

  The mesh sheet 54 is supported by being attached to the holding member 55 by bonding a back surface 54b (not shown) to the outer surface of the sack portion 55a with an adhesive. When the mesh sheet 54 is attached to the finger F, the mesh sheet 54 is disposed at a position so as to cover at least the first joint from the first joint of the finger F inserted through the opening 55b. Further, the mesh sheet 54 is disposed with respect to the holding member 55 so that the weaving direction V coincides with the vertical direction of FIG.

  In the mesh 53 of the mesh sheet 54, the warp yarns 52v and the weft yarns 52h are exposed on both the front surface 54a side and the back surface 54b side. That is, the mesh sheet 54 is affixed to the holding member 55 by bonding both the warp 52v and the weft 2h to the outer surface of the sack portion 55a on the back surface 54b. Other configurations are the same as those in the first embodiment.

  The user fits the sac portion 55a to the finger F, and pushes a part or all of the mesh sheet 54 outward from the back surface 55c of the bag body to the sac portion 55a through the bag body of the sack portion 55a. be able to. Then, these surfaces can be cleaned by rubbing parts such as teeth, gums, palate, and inner cheek in the oral cavity M with the surface 54a of the mesh sheet 54.

  At this time, since the finger tip portion Fa touches the site in the oral cavity M via the thin sac portion 55a, the tactile sensation is easily transmitted to the user's finger F. Therefore, the user can easily find a part that needs cleaning, and can easily adjust the force applied to the finger F for cleaning.

  Further, since both the entangled warps 52v and the weft 52h are bonded to the holding member 55, the mesh 53 may be deformed with respect to the holding member 55 even when a force due to friction or the like is applied. small. Therefore, even when the user repeatedly rubs the site in the oral cavity M, the oral cleaning tool 51 is less likely to change its shape such as the synthetic fibers 52v and 52h fraying, and can maintain the original cleaning effect. .

  Note that the number of fingers F that the user inserts inside the sac portion 55a is not limited to one, and part or all of the mesh sheet 54 is placed by the finger tip portion Fa through the bag body of the sack portion 55a. 2 or more may be used as long as it can be pushed outward from the back surface 55c of the bag body to the sack portion 55a.

  The material of the sack portion 55a is not limited to rubber, and may be a synthetic resin such as a thermoplastic elastomer as long as it is a stretchable material. Further, the method of attaching the mesh sheet 54 is not limited to adhesion by an adhesive, and may be, for example, heat welding with a synthetic resin sack portion 55a.

  Furthermore, the mesh sheet 54 may be disposed not only at a position where it is pressed by the finger tip portion Fa, but also, for example, so as to surround the entire circumference of the sac portion 55a.
