Abstract

(57) [Abstract] [Purpose] To remove the plaque adhering to the narrow groove on the occlusal surface of the posterior tooth in the cleaning effect of the toothbrush tip of the toothbrush. [Structure] In a toothbrush having a rod-shaped handle 1, a flock hole 2 provided on a flock base 8 from an upper stage to a lower stage has a center line C.
It is characterized in that the brush tips 3 of the brushes are alternately shifted rightward and leftward with respect to each other with respect to the axis, and the bristle tips 3 are planted in symmetrical positions toward the center line C.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the development of a toothbrush for the purpose of removing the plaque adhering to the narrow groove of the occlusal surface of the posterior tooth in the scrubbing effect of the toothbrush tip of the toothbrush.

[0002]

[Prior art]

 To remove plaque, it is necessary to enhance the brushing effect, but if the number of flocked hairs is increased too much, the handle of the brush may deteriorate in strength.

[0003]

[Problems to be solved by the device]

 The present invention relates to a toothbrush having a rod-shaped handle 1 for enhancing the brushing effect. In the toothbrushing base 8, the flocking holes 2 provided from the upper stage to the lower stage have the centerline C as the right and left directions in each stage. The brush tips 3 of the brushes are alternately staggered on the left and right sides of the brush so that the tips 3 of the brushes are symmetrically arranged toward the center line C. Dust can be effectively removed by using a rolling or vibrating brushing operation.

[0004]

[Means for Solving the Problems]

 According to the present invention, in a toothbrush having a rod-like handle, the bristles provided from the upper stage to the lower stage are arranged so as to be alternately shifted rightward and leftward in each stage around the center line C as an axis, and the brush tips are The structure is such that the flocking is performed in symmetrical positions toward the center line C, and the front end and the rear end of the flocking holes may be installed symmetrically with respect to the center line C.

[0005]

[Action]

 The toothbrush with the above-mentioned configuration causes the brush tip to have an unprecedented scrubbing effect by implanting bristles from the right or left in each step, and plaque adhered to a narrow groove such as the occlusal part of the back tooth. Can be removed.

[0006]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partial plan view showing a state of flocking of the toothbrush of the first embodiment, and FIG. 2 is a partial perspective view of the toothbrush of the first embodiment. FIG. 3 is a cross-sectional view taken along the lines AA and BB in FIG. 1, showing a tilted state of the planted hair.

In the toothbrush of the first embodiment, a bristling table 8 is formed at the tip of the rod-shaped handle 1, and the position of the bristling holes 2 provided in the flocking table 8 from the upper stage to the lower stage and the inclination of the bristles. 3, as shown in FIG. 3, the bristles 2 are arranged with the center line C as an axis and are staggered alternately in the right direction and the left direction, and the bristle tips 3 of the brush are symmetrical with respect to the center line C. It is in a state where hair is planted at the position.

FIG. 4 is a partial plan view showing a bristling state of the toothbrush according to the second embodiment. In the position of the flocking holes 2 provided on the flocking table 8 from the upper stage to the lower stage and the inclination of the bristles, the upper stage portion and the lower stage portion are arranged. Similar to a normal toothbrush, the part is a vertical flocking part 6 in which bristles are vertically flocked, and the other middle part is such that the flocking holes 2 are alternately shifted to the left or right for each step and the bristles of the brush are arranged. The tip 3 is in a state where the hairs are planted in symmetrical positions toward the center line C.

[0009]

[Effect of device]

 In the toothbrush of the present invention, since the bunch of hairs are alternately planted from the left and right directions toward the center line C, concentrated brushing pressure can be applied to narrow grooves such as the occlusal portion of the back teeth. The effect of effectively removing dental plaque is obtained.
