JP 2011-83462 A

  In the oral cavity brush (toothbrush) disclosed in Patent Document 1, a normal toothbrush and a one tuft are integrated as described above, and more specifically, the one tuft is attached to the tip of the brush base. Only one is provided. For this reason, when brushing teeth and interdental portions with the brush for oral cavity disclosed in Patent Document 1, there is a problem that the one-tuft must be passed through the same portion multiple times. . Further, in order to pass a single one tuft a plurality of times through the same portion, a user's use skill is required, and thus there is a problem that no one can perform appropriate brushing.

  Therefore, an object of the present invention is to provide an intraoral brush capable of efficiently and appropriately brushing a hairline and an interdental portion regardless of a user's use skill.

As a result of intensive studies by the inventor in order to solve the above-mentioned problems, the following configuration has been conceived.
That is, the present invention comprises a brush base, a brush portion having a plurality of hair bundles planted in a matrix in the brush base, and a neck portion formed integrally with the brush portion. The first hair bundles planted on the same row along the short direction of the brush base at the midway position in the longitudinal direction of the brush part are first planted in other parts of the brush base. The brush for oral cavity characterized by protruding from the hair bundle of No. 2 and having a ridge line portion at the upper end portion.

  Thereby, the brushing using the ridgeline part by the 1st hair | bristle bundle can be performed with respect to the hairline, the interdental part, and the peripheral part of the interdental part. Thus, the user can perform the normal brushing operation and the length of the first hair bundle abutting length against the tooth growth, the interdental portion, and the peripheral portion of the interdental portion when the brush base makes one reciprocation ( The time during which the tip of the first hair bundle is in contact with the portion to be brushed) is greatly increased, and the brushing efficiency can be improved.

  Moreover, it is preferable that all the said 1st hair | bristle bundles have the same protrusion height from the said brush stand. Thereby, the front-end | tip parts of the adjacent 1st hair | bristle bundle can be arranged in a straight line in the same height position, and the front-end | tip of the 1st hair | bristle bundle with respect to the hairline, the interdental part, and the peripheral part of an interdental part The partial contact length can be further increased.

  Moreover, it is preferable that the said 1st hair | bristle bundle is planted by the several row | line | column adjacent to the longitudinal direction of the said brush stand. As a result, a ridge line portion is formed by a plurality of hair bundles, the amount of brush hairs to be brought into contact with the interdental portion can be increased, and the rigidity of the brush hair at the portion to be brought into contact with the interdental portion ( Since the stiffness can be increased, tooth brushing can be performed more reliably.

  Moreover, it is preferable that the said 1st hair | bristle bundle is formed with the hair material harder than the said 2nd hair | bristle bundle. Thereby, the brushing effect by the 1st hair | bristle bundle can be improved further.

  By adopting the configuration of the brush for oral cavity according to the present invention, the user can perform the normal brushing operation, and the brushing base and the interdental portion and the periphery of the interdental portion when the brush base passes the brushing portion. The tip portion contact length of the first hair bundle with respect to the portion (the time during which the tip portion of the first hair bundle is in contact with the portion to be brushed) can be greatly increased, and efficient and appropriate brushing is performed. It becomes possible.

(First embodiment)
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an intraoral brush according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the intraoral brush 10 in the present embodiment includes a brush part 20 and a handle 30 integrally formed with the brush part 20. The brush portion 20 and the handle 30 are connected via a neck portion 40 that connects the brush portion 20 and the handle 30. The neck portion 40 is formed with a narrower dimension than the brush portion 20 and the handle 30. In this embodiment, the brush part 20 (brush base 22), the handle 30, and the neck part 40 are integrally formed.

  The brush unit 20 includes a brush base 22 and a plurality of first hair bundles 24 and second hair bundles 26 implanted in the brush base 22. The first hair bundle 24 and the second hair bundle 26 are implanted in the brush base 22 in a matrix arrangement (matrix arrangement). More specifically, the first hair bundles 24 are planted in a line (on the same line) along the short direction of the brush base 22 at the longitudinal center (longitudinal position in the longitudinal direction) of the brush base 22. A second hair bundle 26 is implanted in the brush base 22 so as to sandwich the first hair bundle 24 on both sides in the longitudinal direction of the first hair bundle 24.

  The first hair bundle 24 has a higher protruding height from the brush base 22 than the second hair bundle 26, and the protruding height of the first hair bundle 24 from the brush base 22 is equal. . The protruding height of the second hair bundle 26 from the brush base 22 is also formed to be equal. The first hair bundle 24 is preferably formed of a hair material harder than the second hair bundle 26.

  Furthermore, a ridge line portion 24 </ b> A is formed at the upper end portion of the first hair bundle 24. The ridge line portion 24 </ b> A is formed in a state where it matches the diameter of the first hair bundle 24 when the first hair bundle 24 is viewed in plan. Specifically, over the required height range on the upper end side of the first hair bundle 24, the first hair bundle 24 has a first position from the opposite position (the outer peripheral surface position of the first hair bundle 24) on the same diameter. Two cuts gradually approaching toward the upper end portion of the first hair bundle 24 while maintaining the width dimension of the first hair bundle 24 (the dimension of the diameter perpendicular to the same diameter in the first hair bundle 24) It is formed in a shape having surfaces 24B and 24C. By arranging the plurality of first hair bundles 24 having such a shape in one row (on the same row), each ridge line portion 24A has a straight line shape extending along the short direction of the brush base 22. The point which forms the ridgeline 28 is characteristic.

  In the present embodiment, the distal end portion of the second hair bundle 26 is cut into a plane (horizontal plane) parallel to the upper surface of the brush base 22.

  The use state of the intraoral brush 10 thus formed will be described with reference to FIG. In FIG. 3, (A) is the description which shows the state which brushes the part between teeth using the brush for intraoral of this embodiment, (B) is the brush for intraoral in the prior art (toothbrush which has a one tuft). It is explanatory drawing which shows the state which brushes the part between teeth.

  As shown in FIG. 3A, the intraoral brush 10 according to the present embodiment can be brought into contact with the interdental portion 50 to be brushed with the ridge line 28 formed on the brush portion 20 as a guide. That is, the ridge line 28 is in contact with the tooth 52 in the interdental portion 50 over the length (product of the number of the first hair bundles 24 and the width of the ridge line portion 24A) in the height direction. On the other hand, the conventional intraoral brush having a one-tuft can be brought into contact with the interdental portion 50 to be brushed with the one-tuft 60 as a guide as shown in FIG. It is the same. However, in addition to the one tuft 60 being one, the upper end portion of the one tuft 60 is formed in the conical shape portion 62, so the range in which the conical shape portion 62 of the one tuft 60 is in contact with the interdental portion 50 is not limited to this. This is a slight range compared to the embodiment.

  The user moves the ridgeline 28 or the conical shape portion 62 in the extending direction of the interdental portion 50 (the height direction of the teeth 52) while the ridgeline 28 of the brush portion 20 or the conical shape portion 62 of the one tuft 60 is brought into contact with the interdental portion 50. ) And the teeth 52 that form the interdental portion 50 are brushed. At this time, since the ridge line 28 is formed along the extending direction of the interdental portion 50 in the intraoral brush 10 of the present embodiment, the contact length between the interdental portion 50 and the ridge line 28 is set to the interdental portion. 50 and the conical shape portion 62 can be made significantly longer than the contact length. Further, since the ridge line 28 is in contact with the interdental portion 50 over a required range, when the brush portion 20 is reciprocated along the interdental portion 50, the ridgeline 28 and the interdental portion 50 in the return path The probability of matching the contact state with the contact state between the ridge line 28 and the interdental portion 50 in the forward path can also be increased.

  As described above, by using the intraoral brush 10 in the present embodiment, the brushing effect on the interdental portion 50 to be brushed and the teeth 52 forming the interdental portion 50 as compared with the intraoral brush in the prior art is achieved. It can be greatly improved. In this way, efficient and appropriate brushing can be performed regardless of the use skill of the user, so it is possible to improve the cleaning effect in the oral cavity while shortening the time required for brushing teeth Can contribute to improving the quality of life of the elderly.
