The bristle part of a toothbrush is integrally formed of synthetic resin or the like, and the bristle is implanted therein. Therefore, if a user wants to use a toothbrush with a different size of bristles due to the condition of the oral cavity or other reasons, it is necessary to replace the entire toothbrush with a new one. It is impossible to change the size of . Furthermore, in manufacturing, it is necessary to prepare molds for toothbrushes with different sizes of bristles, which is a cause of increased costs.

This proposal was made to solve the above-mentioned problems, and its gist is that the flocked part is composed of an appropriate number of pieces divided in the length direction, and each piece is divided into one piece. An engaging convex portion whose tip is slightly larger than the base is protruded from the end surface, and a surface opposite to the engaging convex portion of the adjacent piece, which is opposite to the surface on which the engaging convex portion is formed, has a surrounding area. Continuous cuts are carved on the outer surface of the piece at appropriate locations, and an engagement recess is formed in which the mouth side is set slightly smaller than the back side, and the engagement protrusion is elastically fitted into the engagement recess. It is characterized by being formed by connecting pieces, and by adjusting the number of pieces, the size of the flocked part can be made arbitrarily.

To explain the toothbrush of the present invention with reference to the embodiment shown in the drawings, reference numeral 1 denotes a rod-shaped handle made of synthetic resin, and a bristle part 3 is formed at one end of the handle through a neck part 2. The flocked part 3 is made up of a base part 4 formed integrally with the neck part 2, and an appropriate number of pieces 5 separably connected to the base part 4. Details of each piece 5 are shown in FIGS. 3 and 4. Each piece 5 has an engaging protrusion 6 protruding from approximately the center of one end surface, the tip of which is slightly larger than the base, and an adjacent protrusion on the opposite side of the surface on which the engaging protrusion 6 is formed. An engagement recess 7 is formed on the surface of the piece 5 facing the engagement protrusion 6 for receiving the engagement protrusion 6, the mouth side of which is set slightly smaller than the back side. A continuous cut 8 is carved on the periphery of the engagement recess 7 to the upper surface of the piece 5 and the lower surface of the piece 5,
The engaging recess 7 is configured to be able to elastically expand around the cut 8.

To assemble a toothbrush with such a configuration, insert the engaging convex portion 6 of the other piece 5 into the engaging concave portion 7 of the piece 5.
is pushed in, and the engaging protrusion 6 is elastically fitted into the engaging recess 7 while expanding the engaging recess 7 around the cut 8 . The distal end of the engagement protrusion 6 is wider than the mouth of the engagement recess 7, but since the engagement recess 7 has a cut 8, it is difficult for the engagement protrusion 6 to fit into the engagement recess 7. It's easy. Engagement protrusion 6 accommodated in engagement recess 7
The large diameter portion on the distal end side is accommodated in the enlarged diameter portion within the engagement recess 7, and the base portion thereof is held between the mouth portion of the engagement recess 7. Since the opening of the engagement recess 7 has the cut 8, an elastic restoring force acts thereon, and the engagement protrusion 6 is held extremely firmly by the opening. In this way, an appropriate number of each piece 5 is connected to form a flocked part 3 of the desired size.

Since the assembled pieces 5 are firmly connected, they will not separate even when subjected to impact during brushing.

In addition, if a particular piece 5 becomes worn or if it is necessary to change the size of the flocked part 3, pull each piece 5 toward the tip of the flocked part 3 with a slightly strong force to open the cut 8. The engaging recess 7 is expanded at the center to separate each piece 5.

Reference numeral 9 denotes bristle-planting holes provided in the base 4 and each piece 5, into which synthetic fibers 10 or natural bristles are planted to form a toothbrush. The number of the flocking holes 9 in the width direction of the handle 1 in the piece 5 may be one example or a plurality of rows, and may be formed arbitrarily.

The bristle part of this toothbrush has an appropriate size and is constructed by connecting a plurality of pieces 5 on which synthetic fibers 10 and the like are planted, and the pieces 5 can be separated. Therefore, during manufacturing, the flocked part 3 can be changed by simply changing the number of pieces 5 to be connected.
It is possible to get toothbrushes of different sizes,
Since pieces 5 of the same size can be used for several types of toothbrushes, manufacturing costs can be reduced. Since a cut 8 is made on the periphery of the engagement recess 7 of each piece, the engagement recess 7 of the engagement protrusion 6
It is easy to insert and remove the pieces, and the elastic restoring force is strong, so after fitting, the base of the engaging protrusion 6 can be strongly held to maintain the connected state of the adjacent pieces.

The user can separate the piece 5 of the bristle part 3 of the purchased toothbrush depending on the situation, such as when the bristle part 3 is too large or the condition of the oral cavity.
It is possible to reduce the size of the toothbrush and obtain a toothbrush that is suitable for the user. Conversely, if you want to make the flocked part 3 larger, add piece 5.
The purpose can be easily achieved and the brushing effect can also be improved. The connection of the piece 5 to the base 4 and the connection of each piece 5 are made by connecting the engagement protrusion 6 whose tip end is slightly larger than the base to the engagement recess 7 whose opening width is narrower than the width of the back side. It is elastically inserted. Therefore, each piece will not separate due to the tensile force associated with brushing. Moreover, each piece can be slightly separated or brought into close contact by elastic deformation of the engaging recess 7 while maintaining the connected relationship.
It is possible to impart elastic force to the flocked portion 3 in the length direction. Therefore, since the rigidity in the longitudinal direction is lower than that of the conventional flocked part, which is formed entirely in one piece, if an unnecessarily large force is applied to the handle 1 during brushing, the force will be reduced. Since the flocked part 3 absorbs the hair by bending in its length direction, it is possible to avoid the problem of the brushing force being too large and causing defects at the base of the teeth, etc., and remove dental plaque. Alternatively, it may also contribute to performing brushing suitable for gingival pine surge.
