Abstract

(57) [Summary] [Constitution] A flocked base portion is provided at the tip of a handle, and the flocked base portion is curved in a back concave shape along the longitudinal direction of the handle, and the bristle bundle is placed on the surface of the flocked base portion. This is a toothbrush that has been planted substantially vertically. [Effect] Since it is easy to polish the inner peripheral surface of the dentition, it is difficult for unpolished residue to occur, and it is easy to clean between teeth with a hair bundle.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a toothbrush.

[0002]

[Prior art]

 In the conventional toothbrush P, as shown in FIG. 3, a flocked base portion 20 is provided at the tip of the handle 10, a bristle bundle 30, 30,... Is planted on the flocked base portion 20, and the bristle bundles 30, 30,. The tip of the hair bundle group C is formed in a curved convex shape. The hair bundle group C having the curved convex shape makes it easy to polish the inner peripheral surface of a human dentition. .

[0003]

[Problems to be solved by the invention]

 However, in such a conventional toothbrush P, since the bristle bundles 30, 30,... Are planted in parallel with each other, the distal end surface thereof cannot contact the inner peripheral surface of the tooth row substantially perpendicularly. As a result, there is a disadvantage that it is difficult to polish the inner peripheral surface of the dentition, and unpolished residue is apt to occur.

[0004] The problem of the present invention is to eliminate such disadvantages.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in a toothbrush according to the present invention, a flocked base portion is provided at a tip of a handle, and in a toothbrush in which a bristle bundle is planted on the flocked base portion, the flocked base portion is connected to a longitudinal portion of the handle. Since the bristle bundles are bent substantially perpendicularly to the surface of the flocking base portion while being curved in a back concave shape along the direction, the bristle bundles in the flocking base portion extend substantially radially, and as a result, the distal end surface thereof Can contact the inner peripheral surface of the tooth row substantially perpendicularly.

[0006] If only the tip of the flocked base portion is curved into a back concave shape and the other portion is flush with the handle, the planar portion of the flocked base portion is moved up and down. Thereby, the surface of the front teeth can be easily brushed.

[0007]

Embodiment

 FIG. 1 is a front view of the toothbrush according to the present invention, and FIG. 2 is a right side view thereof.

In the figure, B is the toothbrush according to the present invention, and 10 is its handle. The handle 10 is in the form of a stick made of synthetic resin or the like, and is in the form of a so-called ordinary toothbrush handle. Reference numeral 20 denotes a flocking base portion, which is integrally connected to the tip of the handle 10 by a synthetic resin. Reference numeral 21 denotes a plane portion of the flocked base portion 20, which is connected to the handle 10 in a flush state. Reference numeral 22 denotes a curved portion of the flocking base portion 20. The curved portion 22 of the flocked base portion 20 is curved in a concave shape on the back side along the longitudinal direction of the handle 10. The curvature of this curvature is substantially matched to the inner peripheral surface of the human dentition to be used.

Are hair bundles, which are planted on the surface side of the flocking base portion 11. The bristle bundle 20 is formed by bundling a plurality of approximately 50 brush bristles made of synthetic resin or the like, and is positioned substantially perpendicular to the surface of the flocking base portion 11. For this reason, the hair bundles 30 planted on the flat portion 21 of the flocking base portion 20 are substantially parallel to each other, whereas the hair bundles 30 planted on the curved portion 22 of the flocking base portion 20. The distal end surface of the hair bundle group C is curved substantially in parallel with the curved portion 22. The interval between the hair bundles 22, 22 adjacent to the curved portion 22 of the flocking base portion 20 gradually widens toward the tip.

The curved portion 22 of the flocking base portion 20 is a feature of the present invention, but the flat portion 21 functions like a conventional toothbrush.

[0011]

[Effect of the invention]

 The toothbrush according to the present invention has a flocked base portion provided at the tip of a handle, and in a toothbrush having a bristle bundle planted on the flocked base portion, the flocked base portion is curved in a back concave shape along the longitudinal direction of the handle. Since the bristle bundle is implanted substantially perpendicularly to the surface of the flocking base portion, the bristle bundle in the flocking base portion extends substantially radially, so that the distal end surface is substantially perpendicular to the inner peripheral surface of the tooth row. That can be contacted.

[0012] Therefore, when this toothbrush is used, the inner peripheral surface of the tooth row is easily polished, so that unpolished residue is less likely to occur than in the conventional case.

[0013] Furthermore, the distance between the bristle bundle and the bristle bundle gradually increases toward the tip thereof, so that the bristle bundle easily penetrates between the teeth in the dentition. It is easy to clean. This effect is remarkable on the outer peripheral surface of the tooth row.

If only the tip of the flocking base portion is curved in a concave shape on the back surface and the other portion is flush with the handle, the flat portion of the flocking base portion moves up and down. Thereby, the surface of the front teeth can be easily brushed.
