Description

[Technical Field]

[0001] The present invention relates to a tongue coating remover. [Background technology]

[0002] Conventionally, tongue coating removers have been known that use fabrics made from processed fibers such as nonwoven or woven fabrics in the area where tongue coating is removed. Patent Document 1 discloses a tongue coating removal brush in which the brush section is detachable from the handle and can be replaced by a spare, with the brush section made of a specially shaped, three-dimensionally molded nonwoven fabric or pad, the peripheral edge of which is folded and fixed to the brush base with a fixing ring. Patent Document 2 discloses a tongue coating remover in which a nonwoven fabric can be detachably attached to a support using an adhesive or hook-and-loop fastener. Patent Document 3 discloses a tongue cleaner that can be detachably attached by fitting a scrubbing member made of a three-dimensional knitted fabric into the head. Non-Patent Document 1 also discloses that the cotton fiber used in the fabric remover expands in volume by 42% to 44% upon water absorption. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3851338 [Patent Document 2] Japanese Patent Application Publication No. 11-113931 [Patent Document 3] Patent No. 4417317 [Non-patent literature]

[0004] [Non-Patent Document 1] Toshihiro Urahata, "Drying Mechanism of Fibers," Textile Engineering, Vol. 20, No. 1, 1967, pp. 54-64, [online], [Retrieved February 17, 2022], Internet<URL:https: / / www.jstage.jst.go.jp / article / transjtmsj1965a / 20 / 1 / 20_1_P54 / _pdf> Summary of the Invention [Problem to be solved by the invention]

[0005] The tongue coating removal brush described in Patent Document 1 not only requires special three-dimensional molding of the nonwoven fabric, but also requires the brush unit, including the nonwoven fabric, fixing ring component, and brush base, to be replaced after use, resulting in the problem of high replacement part costs. Furthermore, the tongue coating remover described in Patent Document 2 requires the provision of an adhesive or hook-and-loop fastener between the nonwoven fabric and the support, which requires processing of the nonwoven fabric, resulting in the problem of high replacement nonwoven fabric costs. Furthermore, the tongue cleaner described in Patent Document 3 has a scrubbing member that is a specially knitted fabric with a three-dimensional knit structure, resulting in the problem of high replacement scrubbing member costs.

[0006] Therefore, to reduce the cost of replacement parts for tongue coating removers, it is preferable to use general-purpose woven or nonwoven fabrics that are not specially processed, as in Patent Documents 1 to 3. However, for example, if a commercially available cotton puff is used as a replacement part for a tongue coating remover, the user may repeatedly rub the cotton puff against the tongue surface while forcing it down, which may cause the cotton puff to deform due to friction. In particular, Non-Patent Document 1 describes that, since the cotton puff is primarily made of cotton fiber, it absorbs saliva and expands in volume by 42% to 44% when repeatedly rubbed against the tongue surface, as described above. Therefore, even if a commercially available cotton puff is used with the tongue coating removers described in Patent Documents 1 to 3, the cotton puff may sag or wrinkle during use, reducing the area of ​​the portion effective for removing tongue coating or causing a misalignment between the movement of the tongue coating remover and the movement of the cotton puff, potentially reducing its ability to remove tongue coating.

[0007] The present invention has been made in view of the above-mentioned circumstances, and aims to make it easier to maintain the ability to remove tongue coating even when using a general-purpose cloth. [Means for solving the problem]

[0008] In order to achieve the above object, a tongue coating remover according to the present invention removes tongue coating by rubbing a cloth against the tongue. The tongue coating remover comprises a first holding member and a second holding member that hold the cloth. The first holding member includes a first holding member main body that is the main body of the first holding member. The second holding member includes a second holding member main body that is the main body of the second holding member. A through hole that passes through the first holding member main body is formed in the first holding member. In the tongue coating remover, after the cloth is placed between the first holding member main body and the second holding member main body, one end of the second holding member main body passes through the through hole and the second holding member main body fits into the through hole, thereby holding the cloth between the first holding member main body and the second holding member main body, and a portion of the cloth that is in contact with one end of the second holding member main body protrudes from the through hole. [Effects of the Invention]

[0009] According to the present invention, the cloth is held in a state in which its protruding portion is supported by one end of the second holding member body and pulled from the portion sandwiched between the first holding member body and the second holding member body toward the other end of the second holding member body. Therefore, the tongue coating remover according to the present invention is less susceptible to deformation of the cloth due to friction than a tongue coating remover in which the portion of the cloth that is in contact with one end of the second holding member body that passes through the through hole when holding the cloth does not protrude from the through hole, and the cloth is less likely to sag or wrinkle even if it absorbs saliva and expands during use. As a result, the tongue coating remover according to the present invention can easily maintain its ability to remove tongue coating even when a general-purpose cloth is used.

DETAILED DESCRIPTION OF THE INVENTION

[0011] A tongue coating remover according to an embodiment of the present invention will be described in detail below with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals. To facilitate understanding of the configuration of the present invention, the X direction of the arrows shown in the drawings will be referred to as "front" or "front," the -X direction as "back" or "back," the Y direction as "left," the -Y direction as "right," the Z direction as "up," and the -Z direction as "down."

[0012] [Embodiment 1] (Regarding the tongue coating remover 100 according to the first embodiment) The tongue coating remover 100 according to the first embodiment of the present invention is a device for removing tongue coating by rubbing a cloth against the tongue. Here, the cloth may be, for example, a commercially available, general-purpose, disposable nonwoven fabric, woven fabric, or sheet-like knitted fabric. The cloth may also be, for example, a cotton puff in which raw cotton is sandwiched between two sheets of nonwoven fabric. That is, the cloth may be a combination of multiple types of fiber materials, such as nonwoven fabric, woven fabric, knitted fabric, and raw cotton, as in the case of a cotton puff. Furthermore, the cloth is not limited to a general-purpose product, but may also be a dedicated product specially processed for the tongue coating remover 100, as in the above-mentioned Patent Documents 1 to 3. As shown in FIG. 1 , the tongue coating remover 100 includes a first holding member 110 and a second holding member 120 for holding the cloth 1.

[0013] (Regarding the first holding member 110 according to the first embodiment) The first holding member 110 includes a ring-shaped first holding member main body 111. Accordingly, the first holding member 110 is formed with a through-hole 112 that penetrates the first holding member main body 111 in the front-rear direction and has a circular cross section on the YZ plane perpendicular to the central axis. The first holding member 110 also includes a first extension portion 113 that extends downward from the lower end of the first holding member main body 111. An inner circumferential surface 114 of the first holding member main body 111 functions as a holding portion that holds the cloth 1 between itself and the second holding member 120. A plurality of ridges 115 as an example of a first holding portion are formed at intervals on the inner circumferential surface 114. The ridges 115 protrude inward toward the central axis of the through-hole 112 and extend along the front-rear direction. Accordingly, a plurality of grooves 116 as an example of a second holding portion are also formed at intervals on the inner circumferential surface 114, sandwiched between the ridges 115.

[0014] (Regarding the second holding member 120 according to the first embodiment) The second holding member 120 includes a cylindrical second holding member main body 121 that extends in the front-to-rear direction. A front end 122, which is one end of the second holding member main body 121, is chamfered to prevent the fabric 1 from tearing when pressed against the fabric 1. The second holding member 120 also includes a second extension 124 that extends downward from a lower end 123, which is the other end of the second holding member main body 121.

[0015] (Regarding the gripping portion 140 according to the first embodiment) The lower ends of the first extension portion 113 and the second extension portion 124 are rotatably connected by a connecting shaft 131 extending in the left-right direction. Therefore, the first holding member 110 can rotate relative to the second holding member 120 around the connecting shaft 131 as the center of rotation, and the second holding member 120 can rotate relative to the first holding member 110 around the connecting shaft 131 as the center of rotation.

[0016] 2A, the first extension 113 and the second extension 124 have an inverted U-shaped cross section on the XY plane, and the first extension 113 is formed so that its width, which is its length in the left-right direction, is wider than that of the second extension 124. Specifically, the width d between the opposing inner surfaces of the first extension 113 is formed so as to be the same as the overall width of the second extension 124. Therefore, in the tongue coating removal tool 100, when the second holding member 120 is rotated toward the first holding member 110, the first extension 113 and the second extension 124 can be integrated with each other while the second extension 124 is fitted inside the first extension 113, as shown in FIG. 2B. Therefore, in the tongue coating removal tool 100, the first extension 113 and the second extension 124 are integrated with each other to form a gripping portion 140 that can be gripped by a user.

[0017] (Method of attaching cloth 1 to tongue coating remover 100 according to embodiment 1) Next, a method for attaching the cloth 1 to the tongue coating remover 100 will be described. First, the user places the cloth 1 between the first holding member body 111 and the second holding member body 121, as shown in Fig. 1. Next, the user closes the rear of the through-hole 112 with the center of the cloth 1, as shown in Figs. 3 and 4A, and then holds the cloth 1 between both left and right ends of the first holding member body 111 and the user's fingers.

[0018] In this state, the user rotates the second holding member 120 by pressing it toward the first holding member 110 until the first extension 113 and the second extension 124 become integrated. As a result, as shown in FIG. 4B , the front end 122 of the second holding member main body 121 moves forward while pressing against the center of the cloth 1 and passes through the through-hole 112, and the second holding member main body 121 fits into the through-hole 112, thereby holding the cloth 1 between the first holding member main body 111 and the second holding member main body 121. At this time, the center of the cloth 1 in contact with the front end 122 of the second holding member main body 121 is exposed and protrudes forward from the through-hole 112.

[0019] 5, since the ridges 115 protrude toward the second holding member main body 121, a first distance from the ridges 115 to the second holding member main body 121 is shorter than a second distance from the grooves 116 to the second holding member main body 121. Therefore, the portion of the fabric 1 between the ridges 115 and the second holding member main body 121 is pressed against the second holding member main body 121 by the ridges 115. On the other hand, if the fabric 1 is thin, the portion between the grooves 116 and the second holding member main body 121 is not pressed by the grooves 116, and a space may be formed between the portion and the grooves 116.

[0020] As described above, in the tongue plaque removal tool 100 according to this embodiment, the first holding member 110 includes a first holding member body 111, the second holding member 120 includes a second holding member body 121, and the first holding member 110 has a through hole 112 formed therein. In addition, in the tongue plaque removal tool 100, after the cloth 1 is placed between the first holding member body 111 and the second holding member body 121, the front end 122 of the second holding member body 121 passes through the through hole 112, and the second holding member body 121 fits into the through hole 112, thereby holding the cloth 1 between the first holding member body 111 and the second holding member body 121. At this time, in the tongue plaque removal tool 100, the center of the cloth 1 in contact with the front end 122 of the second holding member body 121 protrudes forward from the through hole 112.

[0021] In this manner, the cloth 1 is held in a state in which its protruding center is supported from behind by the front end 122 of the second holding member body 121, while being pulled rearward from the outer portion of the center sandwiched between the first holding member body 111 and the second holding member body 121. Therefore, in the tongue coating removal tool 100 according to this embodiment, deformation of the cloth 1 due to friction is suppressed compared to a tongue coating removal tool in which the portion of the cloth that is in contact with the front end of the second holding member body does not protrude forward from the through-hole when the cloth is held, and sagging or wrinkles are less likely to occur in the cloth 1 even if the cloth 1 absorbs saliva and expands during use. As a result, the tongue coating removal tool 100 can easily maintain its ability to remove tongue coating even when a general-purpose cloth 1 is used.

[0022] Furthermore, according to the tongue coating removal tool 100 of this embodiment, the first holding member 110 includes a first extension 113 extending downward from the first holding member main body 111, and the second holding member 120 includes a second extension 124 extending downward from the second holding member main body 121. In the tongue coating removal tool 100, when the cloth 1 is held between the first holding member 110 and the second holding member 120, the first extension 113 and the second extension 124 become one with each other to form the gripping portion 140.

[0023] By doing so, the user can attach the cloth 1 to the tongue lacquer removal tool 100 and simultaneously grip the gripping portion 140. Furthermore, by doing so, the tongue lacquer removal tool 100 according to this embodiment makes it easier for the user to remove tongue lacquer than a tongue lacquer removal tool in which the first extension portion and the second extension portion do not become integrated when the cloth is held. Furthermore, by doing so, the tongue lacquer removal tool 100 according to this embodiment makes it easier for the user to attach the cloth 1 than a tongue lacquer removal tool in which the first extension portion and the second extension portion become integrated, preventing the cloth from being pinched between the holding member bodies. Furthermore, by doing so, the tongue lacquer removal tool 100 according to this embodiment is more difficult to release from the through-hole 112 of the second holding member body 121 than a tongue lacquer removal tool in which the user does not grip the gripping portion in which the first extension portion and the second extension portion are integrated.

[0024] In the present embodiment, the tongue coating removal tool 100 has the gripping portion 140 formed by integrating the first extension portion 113 and the second extension portion 124, but this is not limited thereto, and the first extension portion 113 and the second extension portion 124 do not have to be integrated. For example, in the tongue coating removal tool 100, the second extension portion 124 may be omitted from the second holding member 120.

[0025] Furthermore, according to the tongue coating remover 100 of this embodiment, a protrusion 115 is formed on the inner circumferential surface 114 of the first holding member body 111, and the distance between the first holding member body 111 and the second holding member body 121 is a first distance. Further, a groove 116 is formed on the inner circumferential surface 114 of the first holding member body 111, and the distance between the second holding member body 121 and the first holding member body 111 is a second distance that is longer than the first distance.

[0026] By doing so, in the tongue coating removal tool 100 according to this embodiment, the expanded portion due to wrinkles occurring in the attached cloth 1 can be accommodated in the groove 116. Furthermore, by doing so, in the tongue coating removal tool 100 according to this embodiment, even if the cloth 1 absorbs saliva and expands during use, sagging and wrinkles are less likely to occur in the cloth 1 than in a tongue coating removal tool in which protrusions and grooves are not formed on the inner peripheral surface of the first holding member body. Specifically, when a space is formed between the held cloth 1 and the groove 116, the expanded portion is absorbed by filling the space. Furthermore, even when no space is formed, the expanded portion can be absorbed by the increased fiber density in the portion of the held cloth 1 filled in the groove 116. As a result, the tongue coating removal tool 100 can more easily maintain its ability to remove tongue coating even when a general-purpose cloth 1 is used.

[0027] As in the present embodiment, it is preferable that the inner circumferential surface 114 of the first holding member body 111 be formed with ridges 115 and grooves 116 that are spaced apart by different distances when the cloth 1 is held between the first holding member body 111 and the second holding member body 121, but this is not limitative. In other words, the inner circumferential surface 114 of the first holding member body 111 does not necessarily have to be formed with the ridges 115 and grooves 116.

[0028] [Embodiment 2] In the tongue coating remover 100 according to the first embodiment, the first holding member body 111 is formed in a ring shape, and the second holding member body 121 is formed in a cylindrical shape. However, the shapes of the holding member bodies 111 and 121 are such that the second holding member body 121 is inserted into the through hole 112. As long as it fits, it is not limited to this. Hereinafter, the tongue coating remover 200 according to embodiment 2 will be described in detail with reference to Fig. 6 and Fig. 7A to Fig. 7C. Note that in embodiment 2, the configuration different from embodiment 1 will be described, and the description of the same configuration as embodiment 1 will be omitted to avoid redundancy.

[0029] (Regarding the tongue coating remover 200 according to the second embodiment) The tongue coating remover 200 according to the second embodiment of the present invention includes a first holding member 210 and a second holding member 220 that hold the cloth 1, as shown in FIG.

[0030] (Regarding the first holding member 210 according to the second embodiment) The first holding member 210 includes a first holding member main body 211 in the shape of a rectangular frame. Therefore, the first holding member 210 is formed with a through-hole 212 that penetrates the first holding member main body 211 in the front-to-rear direction and has a rectangular cross section. The first holding member 210 also includes a gripping portion 213 that extends downward from the lower end of the first holding member main body 211. The first holding member main body 211 is also provided with a pressing portion 214 at the center in the up-down direction of the first holding member main body 211, at the front end that is the opening of the through-hole 212, for pressing the cloth 1 that has passed through the through-hole 212 in a state where it is sandwiched between the first holding member 220 and the first holding member main body 211. The pressing portion 214 is formed in a linear shape that extends from one end to the other end in the left-to-right direction of the first holding member main body 211. In addition, the pressing portion 214 has both left and right ends fixed in a bent state along both left and right side surfaces of the first holding member main body 211, and the center portion in the left and right direction is formed recessed toward the rear through hole 212.

[0031] (Regarding the second holding member 220 according to the second embodiment) The second holding member 220 includes a second holding member main body 221 having a rectangular prism shape. A first protrusion 223, which is an example of a rubbing contact portion and has a rectangular prism shape and protrudes forward, is formed on the lower side of the front end surface 222 of the second holding member main body 221. Furthermore, a second protrusion 224, which is an example of a scraping contact portion and is a ridge that protrudes forward and extends in the left-right direction, is formed on the upper side of the front end surface 222 of the second holding member main body 221. As shown in FIGS. 7A to 7C , the front end of the first protrusion 223 is chamfered to prevent tearing of the cloth 1 when pressed against it. Furthermore, the second protrusion 224 is integrally formed with a movable portion 225, which is an example of a protrusion length adjustment portion that penetrates the upper end of the second holding member main body 221 in the front-rear direction and is movable in the up-down direction.

[0032] (Method of attaching cloth 1 to tongue coating remover 200 according to embodiment 2) Next, a method for attaching the cloth 1 to the tongue coating remover 200 will be described. First, as shown in Fig. 6, the user places the cloth 1 between the first holding member body 211 and the second holding member body 221, and as shown in Fig. 7A, the center of the cloth 1 closes the rear of the through-hole 212. In this state, the user presses the second holding member body 221 toward the front through-hole 212.

[0033] 7B , first protrusion 223 and second protrusion 224 move forward while pressing against the center of cloth 1 and pass through through-hole 212. Furthermore, second holding member main body 221 stops moving when the center of cloth 1 that has passed through through-hole 212 is pressed by front pressing portion 214, sandwiching cloth 1 between pressing portion 214 and front end surface 222. As a result, second holding member main body 221 fits into through-hole 212, and cloth 1 is held between first holding member main body 211 and second holding member main body 221. At this time, the portions of cloth 1 in contact with first protrusion 223 and second protrusion 224 are exposed and protrude forward from through-hole 212. As a result, the portion of cloth 1 in contact with first protrusion 223 forms a rubbing portion 2 that rubs against the tongue, and the portion of cloth 1 in contact with second protrusion 224 forms a scraping portion 3 that can scrape tongue coating. In this state, the user can adjust the protruding length, which is the length by which the scraping part 3 protrudes forward, by moving the movable part 225 in the front-rear direction.

[0034] As described above, according to the tongue plaque removal tool 200 of this embodiment, after the cloth 1 is placed between the first holding member body 211 and the second holding member body 221, the front end of the second holding member body 221 passes through the through hole 212, and the second holding member body 221 fits into the through hole 212, thereby holding the cloth 1 between the first holding member body 211 and the second holding member body 221. At this time, in the tongue plaque removal tool 200, the center of the cloth 1 in contact with the front end of the second holding member body 221 protrudes from the through hole 212. By doing this, the tongue coating removal device 200 of this embodiment can easily maintain its ability to remove tongue coating even when using a general-purpose cloth 1, just like the tongue coating removal device 100 of embodiment 1.

[0035] Furthermore, according to the tongue coating remover 200 of this embodiment, the front end surface 222 of the second holding member body 221 is formed with a first protrusion 223 that comes into contact with the rubbing portion 2 of the cloth 1, and a second protrusion 224 that protrudes further than the first protrusion 223 and comes into contact with the scraping portion 3 of the cloth 1. The user can adjust the protruding length of the second protrusion 224 of the second holding member 220 by moving the movable portion 225 in the front-rear direction.

[0036] In this way, the tongue coating remover 200 according to this embodiment not only removes tongue coating by rubbing the rubbing portion 2 of the cloth 1 against the tongue, but also scrapes the tongue coating from the tongue using the scraping portion 3 of the cloth 1. Furthermore, the tongue coating remover 200 according to this embodiment makes it easier for the user to scrape tongue coating from the tongue than a tongue coating remover in which the user cannot adjust the protruding length of the second protrusion portion using a movable portion. As in the present embodiment, it is preferable that the tongue coating remover 200 is provided with a movable part 225 that allows the user to adjust the protruding length of the second protruding part 224, but the protruding length of the second protruding part 224 does not have to be adjustable by the user. For example, in the tongue coating remover 200, the movable part 225 may be omitted from the second holding member main body 221.

[0037] Furthermore, according to the tongue coating remover 200 of this embodiment, the first holding member body 211 includes a holding portion 214 that is provided at the front end portion which is the opening of the through hole 212 and holds the cloth that has passed through the through hole 212 from the front while sandwiching it between the first holding member body 211 and the second holding member body 221.

[0038] By doing this, the tongue plaque removal tool 200 according to this embodiment is able to suppress deformation of the cloth 1 due to friction compared to a tongue plaque removal tool that does not clamp and hold the cloth that has passed through the through-hole between the front holding part and the rear second holding member main body, and is less likely to sag or wrinkle even if the cloth 1 absorbs saliva and expands during use. As a result, the tongue plaque removal tool 200 is able to more easily maintain its ability to remove tongue plaque even when a general-purpose cloth 1 is used. As in this embodiment, it is preferable that the tongue coating removal device 200 be provided with a pressing portion 214 that presses the cloth 1 from the front after it has passed through the through hole 212, but in the tongue coating removal device 200, the pressing portion 214 may be omitted from the first holding member main body 211.

[0039] [Embodiment 3] In the tongue plaque removal tool 100 according to the first embodiment, the first holding member body 111 does not deform when holding a cloth, but this is not limiting, and for example, the first holding member body 111 may elastically deform when holding a cloth. Hereinafter, the tongue plaque removal tool 300 according to the third embodiment will be described in detail with reference to Figures 8A to 8C. Note that in the third embodiment, configurations different from those in the first embodiment will be described, and redundant descriptions of the same configurations as those in the first embodiment will be omitted.

[0040] (Regarding the tongue coating remover 300 according to the third embodiment) As shown in FIG. 8A, a tongue coating remover 300 according to the third embodiment of the present invention includes a first holding member 310 and a second holding member 320 that hold the cloth 1.

[0041] (Regarding the first holding member 310 according to the third embodiment) First holding member 310 includes first holding member main body 311 and first extension portion 313 similar to first holding member main body 111 and first extension portion 113 according to embodiment 1, and first holding member 310 is formed with through hole 312 similar to through hole 112 according to embodiment 1. An inner circumferential surface 314 of first holding member main body 311 is formed with ridges 315 and grooves 316 similar to ridges 115 and grooves 116 according to embodiment 1. Furthermore, an upper end portion of first holding member main body 311 is integrally formed with leaf spring portion 317 as an example of an elastically deformable cross-sectional area adjusting portion.

[0042] (Regarding the second holding member 320 according to the third embodiment) Second holding member 320 includes second holding member main body 321 and second extension 324 similar to second holding member main body 121 and second extension 124 according to embodiment 1. As shown in FIG. 8C, non-slip portion 323, which is a ripple-shaped uneven surface, is formed on the front end surface of second holding member main body 321. Note that non-slip portion 323 is designed in advance so that the frictional force generated between non-slip portion 323 and cloth 1 is greater than the frictional force generated between the tongue and cloth 1. Returning to FIG. 8A, second holding member main body 321 has tab 327, which is a protruding ridge sandwiched between left and right recesses 326 recessed forward, formed in the center of the rear end surface in the left-right direction.

[0043] (Regarding the gripping portion 340 according to the third embodiment) The lower ends of the first extension portion 313 and the second extension portion 324 are rotatably connected by a connecting shaft 331 similar to the connecting shaft 131 according to embodiment 1. In the tongue coating remover 300, the first extension portion 313 and the second extension portion 324 are integrated together to form a grip portion 340 similar to the grip portion 140 according to embodiment 1.

[0044] (Method of Removing the Cloth 1 from the Tongue Coating Remover 300 According to the Third Embodiment) 8B , in the tongue plaque removal tool 300, similar to the tongue plaque removal tool 100 according to the first embodiment, the front end 322 of the second holding member main body 321 passes through the through-hole 312, and the second holding member main body 321 fits into the through-hole 312, thereby holding the cloth 1 between the first holding member main body 311 and the second holding member main body 321. Here, when the cloth 1 is held between the first holding member main body 311 and the second holding member main body 321, it presses the inner circumferential surface 314 of the first holding member main body 311 radially outward. Therefore, if the cloth 1 of the first holding member main body 311 is thick or hard and difficult to deform, for example, the force pressing the inner circumferential surface 314 radially outward becomes strong, and this may cause the leaf spring portion 317 to elastically deform, thereby increasing the cross-sectional area of ​​the through-hole 312, which is the area of ​​a cross section on the YZ plane.

[0045] Furthermore, in tongue coating removal tool 300, a user can pinch gripping portion 327 and pull second holding member body 321 backward, thereby rotating second holding member body 321 in a direction away from first holding member body 311. As a result, in tongue coating removal tool 300, the retention of cloth 1 by first holding member body 311 and second holding member body 321 is released, and cloth 1 becomes removable.

[0046] As described above, according to the tongue coating remover 300 of this embodiment, the first holding member body 311 is capable of adjusting the cross-sectional area of ​​the through-hole 312 in the YZ plane by the plate spring portion 317. In this way, the tongue plaque removal tool 300 according to this embodiment can adjust the distance, or so-called clearance, between the first holding member body 311 and the second holding member body 321. As a result, the tongue plaque removal tool 300 according to this embodiment can easily hold the cloth 1 between the first holding member body 311 and the second holding member body 321, even if a thick cloth 1 or a cloth 1 that is hard and difficult to deform is selected. Therefore, the user is less likely to have limited options when selecting a general-purpose cloth 1 due to the thickness or hardness of the cloth 1. In this embodiment, the plate spring 317 is used as an example of the cross-sectional area adjustment portion, but the cross-sectional area adjustment portion is not limited to this. For example, the cross-sectional area adjustment portion may be made of an elastic member that can be elastically deformed as long as it can adjust the cross-sectional area of ​​the through-hole 312 in the YZ plane.

[0047] Furthermore, according to the tongue coating remover 300 of this embodiment, the second holding member body 321 has a gripping portion 327 formed at the rear end thereof. In this way, after use, the user can release the hold of the cloth 1 by the first holding member body 311 and the second holding member body 321 by pinching the gripping portion 327 and pulling the second holding member body 321 backward, and can remove the cloth 1 without touching areas that have become soiled during use. As a result, the tongue coating removal tool 300 according to this embodiment makes it easier to replace the cloth 1 than a tongue coating removal tool in which a gripping portion is not formed on the second holding member body.

[0048] Furthermore, according to the tongue coating remover 300 of this embodiment, an anti-slip portion 323 is formed on the front end surface of the second holding member main body 321, and the frictional force generated between the anti-slip portion 323 and the cloth 1 is greater than the frictional force generated between the tongue and the cloth 1. By doing so, in the tongue coating remover 300 according to this embodiment, the cloth 1 is less likely to slip during use than in a tongue coating remover in which no anti-slip portion is formed on the second holding member body. In addition, the tongue coating remover 300 according to this embodiment has the same effects as the tongue coating remover 100 according to the first embodiment.

[0049] [Embodiment 4] In the tongue plaque removal tool 100 according to embodiment 1, the second holding member body 121 does not deform when holding a cloth, but this is not limited thereto, and for example, the second holding member body 121 may elastically deform when holding a cloth. Below, the tongue plaque removal tool 400 according to embodiment 4 will be described in detail with reference to Figures 9A to 9C. Note that in embodiment 4, configurations different from embodiment 1 will be described, and configurations that are the same as embodiment 1 will not be described to avoid redundancy.

[0050] (Regarding the tongue coating remover 400 according to the fourth embodiment) As shown in FIG. 9A, a tongue coating remover 400 according to the fourth embodiment of the present invention includes a first holding member 410 and a second holding member 420 that hold the cloth 1.

[0051] (Regarding the first holding member 410 according to the fourth embodiment) The first holding member 410 includes a first holding member main body 411 similar to the first holding member main body 111 according to the first embodiment. A through hole 412 similar to the through hole 112 according to the first embodiment is formed in the first holding member 410. The first holding member 410 also includes a gripping portion 413 extending downward from the lower end of the first holding member main body 411. A pressing portion 414 that presses the cloth 1 while sandwiching it with the second holding member 420 is formed at the front end of the first holding member main body 411. The pressing portion 414 is formed such that the front end of an inner circumferential surface 415 of the first holding member main body 411 protrudes inward toward the central axis of the through hole 412.

[0052] (Regarding the second holding member 420 according to the fourth embodiment) The second holding member 420 includes a cylindrical second holding member main body 421. The second holding member main body 421 is made of an elastic material such as natural rubber or synthetic rubber, and both front and rear ends of the second holding member main body 421 are chamfered. A cylindrical protrusion 423 that protrudes forward is formed at the center of the front end surface 422 of the second holding member main body 421. The front end of the protrusion 423 is chamfered to prevent the fabric 1 from tearing when pressed against it, and the coefficient of friction of the elastic material is designed in advance so that the friction force generated between the front end surface of the protrusion 423 and the fabric 1 is greater than the friction force generated between the tongue and the fabric 1. A cylindrical gripping portion 427 is formed at the center of the rear end surface of the second holding member main body 421 and is surrounded by a recessed groove 424 that is recessed forward.

[0053] (Method of attaching and detaching the cloth 1 to the tongue coating remover 400 according to the fourth embodiment) 9B and 9C, in the tongue plaque removal tool 400, the protrusion 423 of the second holding member main body 421 passes through the through-hole 412, and the second holding member main body 421 fits into the through-hole 412, thereby holding the cloth 1 between the first holding member main body 411 and the second holding member main body 421. At this time, the center of the cloth 1 that has passed through the through-hole 412 is pressed against the front pressing portion 414, thereby stopping the forward movement of the second holding member main body 421. Furthermore, in the tongue plaque removal tool 400, the user can move the second holding member main body 421 rearward, away from the first holding member main body 411, by pinching the grip portion 427 and pulling the second holding member main body 421 rearward. As a result, in the tongue plaque removal tool 400, the hold of the cloth 1 by the first holding member main body 411 and the second holding member main body 421 is released, and the cloth 1 becomes removable.

[0054] As described above, according to the tongue coating remover 400 of this embodiment, the second holding member body 421 is made of an elastic material, and the portion that fits into the through hole 412 when holding the cloth 1 together with the first holding member body 411 is elastically deformable. In this way, the tongue coating remover 400 according to this embodiment can adjust the clearance between the first holding member body 411 and the second holding member body 421, making it easier to hold the cloth 1 even when a thick cloth 1 or a hard, non-deformable cloth 1 is selected. Therefore, the user is less likely to be limited in his or her options when selecting a general-purpose cloth 1 by the thickness or hardness of the cloth 1.

[0055] In this embodiment, second holding member main body 421 is entirely made of an elastic material, but the configuration for adjusting the clearance is not limited to this. For example, second holding member main body 421 may have only the portion that fits into through hole 412 made of an elastic material, with the other portion made of a resin material such as plastic that does not elastically deform. Also, for example, the portion of second holding member main body 421 that is exposed to the outside may be made of an elastic material, and the internal core portion may be made of a resin material such as plastic.

[0056] Furthermore, according to the tongue coating remover 400 of this embodiment, the second holding member body 421 has a gripping portion 427 formed at the rear end thereof. By doing so, the tongue plaque remover 400 according to this embodiment makes it easier to replace the cloth 1 than a tongue plaque remover in which no gripping portion is formed on the second holding member body.

[0057] Furthermore, according to the tongue coating remover 400 of this embodiment, the second holding member main body 421 is made of an elastic member, and the frictional force generated between the front end surface of the protrusion 423 and the cloth 1 is greater than the frictional force generated between the tongue and the cloth 1. By doing so, in the tongue plaque remover 400 according to this embodiment, the cloth 1 is less likely to slip off during use than in a tongue plaque remover in which the second holding member main body is not made of an elastic material. In this embodiment, second holding member body 421 is entirely made of an elastic material, but the configuration for preventing slipping of fabric 1 is not limited to this. For example, second holding member body 421 may be made of a resin material such as plastic that does not elastically deform, and only the front end surfaces of protrusions 423 may be coated with an anti-slip coating by spraying rubber or the like.

[0058] [Embodiment 5] In the tongue plaque removal tool 100 according to embodiment 1, the part that the user touches when the second holding member body 121 is pulled away from the first holding member body 111 to remove the cloth 1 is not specified, but the part that the user touches may be specified. Below, the tongue plaque removal tool 500 according to embodiment 5 will be described in detail with reference to Figures 10A, 10B, 11A, and 11B. Note that in embodiment 5, configurations that are different from embodiment 1 will be described, and descriptions of the same configurations as embodiment 1 will be omitted to avoid redundancy.

[0059] (Regarding the tongue coating remover 500 according to the fifth embodiment) As shown in FIGS. 10A and 10B, a tongue coating remover 500 according to the fifth embodiment of the present invention includes a first holding member 510 and a second holding member 520 that hold the cloth 1.

[0060] (Regarding the first holding member 510 according to the fifth embodiment) The first holding member 510 includes a first holding member main body 511 similar to the first holding member main body 111 according to the first embodiment, and a through hole 512 similar to the through hole 112 according to the first embodiment is formed in the first holding member 510. The first holding member 510 also includes a first extension portion 513 extending downward from the lower end of the first holding member main body 511. A plurality of groove portions 516 as an example of a second holding portion are formed at intervals on an inner circumferential surface 514 of the first holding member main body 511. The groove portions 516 are recessed radially outward from the through hole 512 and extend along the front-rear direction. Therefore, a plurality of ridges 515 as an example of a first holding portion are also formed at intervals on the inner circumferential surface 514, and are sandwiched between the groove portions 516.

[0061] (Regarding the second holding member 520 according to the fifth embodiment) Second holding member 520 includes second holding member main body 521 similar to second holding member main body 321 according to embodiment 3, and second extension portion 524 extending downward from the center of second holding member main body 521. Second holding member main body 521 is made of an elastic member, and its rear end portion is supported by main body support portion 525 of second extension portion 524.

[0062] (Regarding gripping portion 540 according to embodiment 5) The vertical centers of first extension portion 513 and second extension portion 524 are rotatably connected by connecting shaft 531, which is similar to connecting shaft 131 according to embodiment 1. As shown in FIGS. 10A and 11A, first extension portion 513 has an inverted U-shaped cross section on the XY plane from its upper end to connecting shaft 531, and is provided with through-hole 517 that penetrates in the front-rear direction from connecting shaft 531 to its lower portion. Also, as shown in FIG. 11A, a guide protrusion 519, which protrudes rightward and serves as an example of a guide portion, is formed on the left lower end of an inner surface 518 of first extension portion 513.

[0063] 10A and 11B, second extension portion 524 is formed in a shape that fits into first extension portion 513 from its upper end to its lower end, and a rearward extension portion 526 that extends in an arc toward the rear is formed at the lower end of second extension portion 524. A flat-plate-shaped pressed portion 527 that is pressed by a user's finger is supported on the rear end surface of rear extension portion 526. Also, as shown in FIG. 11B, a guided groove 528 as an example of a guided portion into which guiding protrusion 519 fits is formed on the left end surface of rear extension portion 526. Guided groove 528 is formed in an arc shape extending in the front-rear direction. A first contact portion 529 that contacts guiding protrusion 519 is formed at the front portion of guided groove 528. A second contact portion 530 as an example of a positioning portion that contacts guiding protrusion 519 is formed at the rear portion of guided groove 528.

[0064] In tongue coating removal tool 500, when second holding member 520 is rotated toward first holding member 510, first extension portion 513 and second extension portion 524 can be integrated with each other in a state in which second extension portion 524 is fitted inside first extension portion 513, as shown in Fig. 10B. Therefore, in tongue coating removal tool 500, first extension portion 513 and second extension portion 524 are integrated with each other to form grip portion 540 that can be gripped by the user.

[0065] (Method of attaching and detaching the cloth 1 to the tongue coating remover 500 according to the fifth embodiment) In the tongue plaque removal tool 500, the second holding member 520 is movable between a first position shown in FIG. 10B where the front end 523 of the second holding member main body 521 passes through the through-hole 512 and fits into the through-hole 512, and a second position shown in FIG. 10A where the front end 523 of the second holding member main body 521 is away from the through-hole 512. Thus, the tongue plaque removal tool 500 is able to hold the cloth 1 between the first holding member main body 511 and the second holding member main body 521 by moving the second holding member 520 to the first position. Note that at this time, in the second holding member 520, the guiding protrusion 519 comes into contact with the first contact portion 529, and the guiding protrusion 519 moves over the first contact portion 529 before stopping its movement at the front end of the guided groove 528, thereby positioning the guided groove 528.

[0066] Furthermore, in the tongue coating removal tool 500, the user can, for example, press the pressed portion 527 with the thumb to rotate the second holding member body 521 backward away from the first holding member body 511, thereby moving the second holding member body 521 from the first position to the second position. At this time, in the second holding member 520, the guiding protrusion 519 moves over the first contact portion 529, thereby releasing the positioning of the guided groove 528. Then, in the second holding member 520, the guiding protrusion 519 comes into contact with the second contact portion 530, and after the guiding protrusion 519 moves over the second contact portion 530, the movement stops at the rear end of the guided groove 528, thereby positioning and fixing the guided groove 528. As a result, in the tongue coating removal tool 500, the retention of the cloth 1 by the first holding member body 511 and the second holding member body 521 is released, and the cloth 1 becomes removable. In addition, in the tongue coating removal tool 500, the positional relationship between the guide protrusion 519 and the second contact portion 530 is predetermined so that even if the second holding member 520 moves toward the second position, the pressed portion 527 and the first extension portion 513 do not come into contact with each other before the guide protrusion 519 comes into contact with the second contact portion 530.

[0067] As described above, according to tongue coating remover 500 of the present embodiment, second holding member 520 is movable between a first position and a second position. Also, first holding member 510 is formed with guide protrusion 519 that guides the movement of second holding member 520, and second holding member 520 is formed with guided groove 528 into which guiding protrusion 519 fits, and second contact portion 530 that comes into contact with guiding protrusion 519 when second holding member 520 moves from the first position to the second position to position guided groove 528. By doing this, the tongue coating removal device 500 of this embodiment is more likely to maintain the second holding member 520 stopped in the second position than a tongue coating removal device that does not have a second contact portion formed.

[0068] In particular, according to the tongue coating removal device 500 of this embodiment, the second extension portion 524 supports a pressed portion 527 on the rear end surface of the rear extension portion 526, and the pressed portion 527 does not come into contact with the first extension portion 513 before the guide protrusion portion 519 comes into contact with the second contact portion 530 even when the second holding member 520 moves toward the second position. By doing so, in tongue plaque removal tool 500 according to the present embodiment, second holding member 520 decelerates when guiding protrusion 519 passes over second contact portion 530, and therefore, pressed portion 527 and first extension portion 513 come into contact with each other after second holding member 520 has decelerated. As a result, tongue plaque removal tool 500 according to the present embodiment can reduce the occurrence of impact noise caused by a strong collision between pressed portion 527 and first extension portion 513 compared to a tongue plaque removal tool in which no second contact portion is provided in the guide groove portion.

[0069] [Embodiment 6] In the tongue plaque removal tool 100 according to embodiment 1, the holding member bodies 111, 121 hold the cloth 1 inside the through-hole 112, but the holding member bodies 111, 121 may hold the cloth 1 outside the through-hole 112. Below, a tongue plaque removal tool 600 according to embodiment 6 will be described in detail with reference to Figures 12A to 12C. Note that in embodiment 6, configurations different from embodiment 1 will be described, and configurations that are the same as embodiment 1 will not be described to avoid redundancy.

[0070] (Regarding the tongue coating remover 600 according to the sixth embodiment) A tongue coating remover 600 according to the sixth embodiment of the present invention includes a first holding member 610 and a second holding member 620 that hold the cloth 1, as shown in FIGS. 12A, 12B, and 12C.

[0071] (Regarding the first holding member 610 according to the sixth embodiment) The first holding member 610 includes a first holding member main body 611 in the shape of a thin rectangular plate. A through-hole 612 is formed in the first holding member 610, penetrating the first holding member main body 611 in the front-to-rear direction and having a rectangular cross section on the YZ plane perpendicular to the central axis. A left claw 613 is formed at the left end of the first holding member main body 611 and has a C-shaped cross section on the XY plane when viewed from above downward. A right claw 614 is formed at the right end of the first holding member main body 611 and has an inverted C-shaped cross section on the XY plane when viewed from above downward.

[0072] (Regarding the second holding member 620 according to the sixth embodiment) Second holding member 620 includes second holding member main body 621 in the shape of a thin rectangular plate, and gripping portion 624 extending downward from the lower end of second holding member main body 621. A protruding portion 625 in the shape of a thin rectangular plate that protrudes forward is supported on the front end surface of second holding member main body 621. Protruding portion 625 is made of an elastic material such as natural rubber or synthetic rubber, for example.

[0073] (Method of attaching cloth 1 to tongue coating remover 600 according to embodiment 6) Next, we will explain how to attach the cloth 1 to the tongue coating remover 600. First, the user places the cloth 1 between the first holding member body 611 and the second holding member body 621. Next, the user places the center of the cloth 1 so that the rear of the through-hole 612 is closed.

[0074] In this state, the user presses the second holding member 620 forward toward the first holding member 610 until the front end, which is the free end of the protruding portion 625 of the second holding member body 621, passes through the through-hole 612. As a result, the protruding portion 625 becomes fitted into the through-hole 612. Also, in this state, the user hooks the left claw portion 613 and the right claw portion 614 of the first holding member body 611 onto both ends of the second holding member body 621 in the left-right direction. As a result, the tongue coating removal tool 600 holds the cloth 1 in a state where it is sandwiched between the first holding member body 611 and the second holding member body 621. At this time, the center of the cloth 1 in contact with the front end of the protruding portion 625 is exposed and protrudes forward from the through-hole 612.

[0075] As described above, according to the tongue coating removal tool 600 of the present embodiment, after the cloth 1 is placed between the first holding member body 611 and the second holding member body 621, the front end of the protrusion 625 passes through the through hole 612 and fits into the through hole 612, thereby holding the cloth 1 between the first holding member body 611 and the second holding member body 621. At this time, the center of the cloth 1 in contact with the front end of the protrusion 625 protrudes from the through hole 612. Furthermore, when the first holding member body 611 and the second holding member body 621 hold the cloth 1, the cloth 1 is sandwiched between the first holding member body 611 and the second holding member body 621. By doing this, the tongue coating removal device 600 of this embodiment can make the area from which tongue coating is removed thinner than a tongue coating removal device in which the first holding member body and the second holding member body do not sandwich the cloth 1, making it easier for the user to remove tongue coating.

[0076] [Example of change] In the above-described first embodiment, as shown in FIG. 5, when the holding member bodies 111, 121 hold the cloth 1, the outer end of the cloth 1 located rearward of the through-hole 112 is not held, but this is not limiting. For example, the rear end surface of the second holding member body may include a fastener, such as a hook-and-loop fastener, that can fasten the outer end of the cloth 1. In this way, the tongue coating removal tool 100 is more resistant to slippage of the cloth 1 during use than a tongue coating removal tool that does not have a fastener formed thereon. Furthermore, similar fasteners may also be provided in the above-described second to sixth embodiments.

[0077] In the first embodiment described above, the second holding member body 121 is formed in a cylindrical shape, and in the second embodiment described above, the second holding member body 221 is formed in a rectangular prism shape. However, the second holding member body 121, 221 may have any shape. For example, as shown in FIG. 13, the second holding member body may be formed in a triangular prism shape. In this case, the first holding member body may be formed in a triangular frame shape so that the second holding member body fits into the through-hole. Furthermore, for example, the second holding member body may be formed in the outline shape of an animated character, and the first holding member body may be formed in a frame shape corresponding to the outline of the animated character.

[0078] In the above-described third embodiment, as shown in Fig. 8B, non-slip portion 323, which is a ripple-shaped uneven surface, is formed on second holding member main body 321, but the shape of non-slip portion 323 is not limited to this as long as the frictional force between non-slip portion 323 and cloth 1 is greater than the frictional force between the tongue and cloth 1. For example, non-slip portion 323 may have a shape in which multiple radial lines extending radially are added to the ripples, as shown in Fig. 13.

[0079] In the fourth embodiment described above, the first holding member 410 and the second holding member 420 are not connected to each other. However, the present invention is not limited to this. For example, as shown in FIG. 14 , the second holding member main body 421 and the upper end of the grip portion 413 may be connected by a band-shaped connecting portion 450. This prevents the tongue coating removal tool 400 from accidentally swallowing the second holding member 420 when the second holding member 420 falls out of the through-hole 412 in the mouth during use due to, for example, the second holding member main body 421 not fitting properly into the through-hole 412 or the second holding member main body 421 being strongly pressed backward during use. Furthermore, this configuration reduces the risk of the second holding member 420 being lost when not in use compared to a tongue coating removal tool that does not have a connecting portion.

[0080] 14, one end of connecting portion 450 may be fixed to second holding member main body 421, while the other end may have permanent magnet 451 fixed thereto, so that connecting portion 450 is detachable from ferromagnetic member 452 supported on the upper end of grip portion 413. Here, ferromagnetic member 452 may be, for example, an iron wire wound around the upper end of grip portion 413. In this way, the user can, for example, release the connection by connecting portion 450 when fitting second holding member main body 421 into through-hole 412, making it easier to fit second holding member main body 421 into through-hole 412 than when second holding member main body 421 and grip portion 413 are connected. Note that a similar connecting portion may also be provided in the second embodiment described above.

[0081] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. Furthermore, the above-described embodiments are intended to explain the present invention and do not limit the scope of the present invention.
