In such toothbrushes, the handle and brush section are generally formed by integral molding using a synthetic resin material.

[0003] JP 2016-158643 A

[0004] In conventional toothbrushes, the handle and brush head are integrally molded from synthetic resin, and therefore are not satisfactory for users, particularly in terms of the feel, aesthetics, and texture of the handle.

[0005] An object of the present invention is to provide a toothbrush that can provide a high-quality texture in accordance with personal taste.

[0006] In order to solve the above problems, the present invention provides a toothbrush (1) having long handles (11), (111), a connecting part (13) connected to one end of the handles (11), (111) in the longitudinal direction (P), a bristle part (12) continuing from the connecting part (13), and a brush part (20) consisting of a plurality of bristle bundles planted in the bristle part (12), wherein the toothbrush (1) cleans teeth using the brush part (20), and is characterized in that the handles (11), (111) are made of wood, have a lacquered part (14) formed on at least a portion of their surfaces, and the connecting part (13) is detachably connected to the handle (11).

[0007] In this way, by constructing the handles (11, 111) from wood, forming a lacquered portion (14) on at least a portion of the surface, and detachably connecting the connecting portion (13) to the handle (11), the toothbrush (1) can have a high-quality texture. Furthermore, the wood from which the handles (11, 111) are made can be selected according to the user's preferences, and the area of ​​the lacquered portion (14) can be set, and further decorations can be added. Therefore, the handles (11, 111) can be designed to suit individual tastes. This makes it possible to provide toothbrushes (1, 111) that can achieve a high-quality texture that suits individual tastes.

[0008] Furthermore, in the toothbrushes (1) and (100) configured as described above, the handle (111) may be formed with a longitudinally extending anti-slip portion (15). Forming the anti-slip portion (15) in this manner allows the user to securely grip the handle (11) (111), preventing the user's hand from slipping while brushing, further improving the texture of the toothbrushes (1) and (100).

[0009] Furthermore, the toothbrushes (1), (100) configured as described above may further include a joint member (30) that connects the handle (11), (111) to the connecting portion (13). By including the joint member (30) in this manner, the handle (11), (111) and the toothbrush body (10) can be reliably and detachably connected.

[0010] Furthermore, in the toothbrushes (1) and (100) configured as described above, the joint member (30) may have a disk-shaped flange (31), and the diameter (T2) of the flange (31) may be formed to be equal to or greater than the length (T1) of the handle (111) in the short direction (Q) perpendicular to the longitudinal direction (P). By making the diameter (T2) of the flange (31) equal to or greater than the length (T1) of the handle (111) in the short direction (Q) perpendicular to the longitudinal direction (P), toothpaste, water, etc. from the brush part (20) can be prevented from adhering to the handle (111).

Fig. 2 is an enlarged view of a brush part of the toothbrush, (a) is a plan view, (b) is a side view, and (c) is a front view. Fig. 3 is an exploded perspective view of a toothbrush according to another embodiment of the present invention. Fig. 4 is a front view of a toothbrush according to another embodiment of the present invention.

[0014] <Example 1> Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is an overall view of a toothbrush according to one embodiment of the present invention.

[0015] The toothbrush 1 shown in Figure 1 has a toothbrush body 10 having a long handle 11, a connecting portion 13 connected to one longitudinal end of the handle 11, and a bristle portion 12 connected to the connecting portion 13, and a brush portion 20 consisting of a plurality of central bristle bundles 21 and a plurality of side bristle bundles 22 that are planted in the bristle portion 12.

[0016] The handle 11 of the toothbrush 1 is made of wood. Details of the handle 11 will be described later. The bristle section 12 and the connecting section 13 are integrally formed and made of a synthetic resin material. The bristles that make up the central bristle bundle 21 and the side bristle bundles 22 of the brush head 20 are made of a relatively soft synthetic resin material such as nylon. The brush head 20 of the toothbrush 1 is preferably about 2 cm in size so that it can easily fit into the oral cavity and be maneuverable.

[0017] The brush head 20 of the toothbrush 1 will now be described in detail. Figure 2 is an enlarged view of the brush head 20, with (a) being a plan view, (b) being a side view, and (c) being a front view. As shown in Figure 2, the bristle bundles forming the brush head 20 are classified into two types: a central bristle bundle 21 and a side bristle bundle 22, depending on where they are arranged in the bristle implantation section 12.

[0018] The brush section 20 is composed of a plurality of central bristle bundles 21 arranged along the longitudinal direction P at the center of the bristle section 12, and a plurality of side bristle bundles 22 arranged adjacent to and surrounding the periphery of the central bristle bundles 21.

[0019] Next, the configuration of the central bristle bundles 21 and the side bristle bundles 22 will be described in detail. As shown in Fig. 2(a), the central bristle bundles 21 are composed of multiple bristle bundles and are arranged side by side in the central part of the bristle implantation section 12 in the longitudinal direction P. In this embodiment, an example is shown in which six central bristle bundles 21 are arranged. The multiple central bristle bundles 21 are formed in a mountain-like (pyramid-like) inclination so that they become higher as they approach the center of the brush section 20.

[0020] Specifically, as shown in Figure 2(b), the three tufts on the handle side of the central tuft 21 are inclined so that they linearly increase in height as they approach the tip, while the three tufts on the tip side are inclined so that they linearly decrease in height as they approach the tip. Also, as shown in Figures 2(b) and 2(c), the height of the central tuft 21 is configured to be higher than the adjacent side tufts 22.

[0021] As shown in Figure 2(a), the side bristle bundles 22 are arranged adjacent to the central bristle bundle 21 so as to surround the periphery of the central bristle bundle 21. In this embodiment, an example is shown in which 17 side bristle bundles 22 are arranged around the central bristle bundle 21. Specifically, three side bristle bundles 22 are arranged closest to the handle 11 of the brush head 20 in Figures 2(a) and 2(b). In addition, six side bristle bundles 22 are arranged adjacent to the central bristle bundle 21 in the short direction Q (the direction perpendicular to the longitudinal direction P).

[0022] Therefore, when viewed from the side as shown in Figure 2(b), the roots of the six side bristle bundles 22 appear to overlap with the central bristle bundle 21. Furthermore, two of the side bristle bundles 22 are arranged closer to the tip than the central bristle bundle 21. By limiting the number of bristle bundles on each handle side to three and the number of side bristle bundles 22 on the tip side to two, the width of the tip side of the brush part 20 can be narrowed.

[0023] As shown in FIG. 2(b), the four tufts on the handle side of the side hair tufts 22 are formed with an inclination such that they become linearly higher as they approach the tip, and the four tufts on the tip side are formed with an inclination such that they become linearly lower as they approach the tip.

[0024] As shown in FIG. 2(b), the angle of inclination of the central bristle bundle 21, which is inclined in a mountain shape, is the same as the angle of inclination of the side bristle bundles 22. The hardness of the central bristle bundle 21 is configured to be harder than that of the side bristle bundles 22. In relation to this, the amount of bristles in the central bristle bundle 21 may be greater than the amount of bristles in the side bristle bundles 22. This makes it possible to maintain high rigidity of the brush part 20. In this embodiment, the central bristle bundle 21 is arranged in a single row along the longitudinal direction P, but this is not necessarily limited to one row and multiple rows are also possible. The number of tufts in the central bristle bundle 21 or the side bristle bundles 22 is not limited to that in this embodiment.

[0025] Next, the structure of the handle 11 will be described in detail. The handle 11 is a long, longitudinal member made of wood such as zelkova, cypress, cedar, maras, or ironwood. There are no particular restrictions on the cross-sectional shape of the handle 11 perpendicular to the longitudinal direction, and it may be appropriately selected taking into consideration ease of grip. In this embodiment, the handle 11 is formed in a cylindrical shape.

[0026] A lacquered portion 14 is formed on at least a portion of the surface of the handle 11. In this embodiment, the lacquered portion 14 is formed on the entire surface of the handle 11. The lacquered portion 14 may be decorated with designs, pictures, letters, etc. using a decorative material such as gold leaf.

[0027] The connecting part 13 is detachably attached to the handle 11. In this embodiment, the connecting part 13 has a male thread (not shown) formed at the end of the handle 11. Furthermore, the handle 11 has a female thread (not shown) formed at the end of the connecting part. The connecting part 13 and the handle 11 are detachably connected by screwing the male thread into the female thread. The connection between the handle 11 and the connecting part 13 is not limited to the above structure, and may be an interlocking structure in which a protrusion is provided on the connecting part 13 and a recess is provided on the handle 11 and they are fitted together, or a structure in which a locking claw is provided on the connecting part 13 and a locking part is provided on the handle 11 for locking.

[0028] According to this embodiment, the handle 11 is made of wood and has a lacquered portion 14 formed on at least a portion of the surface, thereby achieving a high-quality texture for the toothbrush 1. Furthermore, the wood from which the handle 11 is made can be selected according to the user's preferences, the area of ​​the lacquered portion 14 can be set, and further decorations can be added. Therefore, the handle 11 can be designed to suit individual tastes. This makes it possible to provide a toothbrush 1 that can achieve a high-quality texture that suits individual tastes.

[0029] Example 2 Next, a toothbrush 100 according to another embodiment of the present invention will be described. To avoid duplication of explanation, the same components as those in the above-described embodiment are denoted by the same reference numerals, and the explanation will be omitted.

[0030] Figure 3 is an exploded perspective view of toothbrush 100. Figure 4 is a front view of toothbrush 100. Toothbrush 100 shown in Figures 3 and 4 has toothbrush body 10 having long handle 111, bristle section 12 formed at the tip of handle 111, and connecting section 13 continuing from bristle section 12 and detachably connected to handle 11, and brush section 20 consisting of multiple central bristle bundles 21 and multiple side bristle bundles 22.

[0031] The toothbrush 100 further includes a joint member 30. The joint member 30 connects the handle 111 and the connecting portion 13 of the toothbrush body 10. The joint member 30 is made of a synthetic resin material.

[0032] Joint member 30 has a disk-shaped flange 31, a first connecting protrusion 32 protruding from one surface of flange 31, and a second connecting protrusion 33 protruding from the other surface of flange 31. First connecting protrusion 32 is connected to handle 111 by fitting into a recess 40 formed in handle 111. Second connecting protrusion 33 is connected to connecting portion 13 by fitting into a recess 41 formed in connecting portion 13. By connecting first connecting protrusion 32 to recess 40 and second connecting protrusion 33 to recess 41, joint member 30 connects handle 111 to toothbrush body 10.

[0033] 4, diameter T2 of flange 31 is longer than widthwise length T1 of handle 111. More specifically, diameter T2 is set to a length obtained by adding widthwise length T1 to lengths T3 at both ends of the widthwise direction when viewed from the front.

[0034] The handle 111 is a long member that extends in the longitudinal direction and is made of wood such as zelkova, cypress, cedar, maras, ironwood, etc. The handle 111 is formed with a non-slip portion 15 that extends along the longitudinal direction.

[0035] The non-slip portion 15 is made of a rubber material. The non-slip portion 15 has a groove 112 formed along the longitudinal direction of the handle 111, and the non-slip portion 15 is formed by inserting and fixing a rubber material into the groove 112.

[0036] According to this embodiment, toothbrush 100 has joint member 30, and flange 31 has diameter T2 that is longer than width T1 of handle 111. This prevents toothpaste, water, and the like from brush head 20 from adhering to handle 111.

[0037] Furthermore, according to this embodiment, toothbrush 100 has handle 111, and handle 111 is formed with anti-slip portion 15 extending along the longitudinal direction. This allows the user to grip handle 111 securely, further improving the texture of toothbrush 100.

[0038] Although an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible within the scope of the claims and the technical ideas described in the specification and drawings.
