TECHNICAL FIELD The present invention relates to a toothbrush that prevents toothpaste mixed with toothpaste and saliva from flowing down from a bristle portion of the toothbrush toward a handle portion when brushing teeth.

To brush your teeth, apply the toothbrush obliquely (at an angle of about 45 degrees) to the boundary between the teeth and gums, and use the bath method in which the toothbrush is vibrated from side to side. There are various methods of brushing, such as the scrubbing method to remove dirt, or the rolling method in which the toothbrush is rotated from the gums toward the teeth. , and a handle.

When brushing teeth, a paste-like dentifrice is generally applied to the bristles of the toothbrush in advance, and the handle is gripped to brush the teeth using the various toothbrushing methods described above.

When brushing teeth in the manner described above, toothpaste mixed with dentifrice and saliva accumulates in the oral cavity, and the toothpaste flows down from the bristles of the toothbrush to the neck and then to the handle. At this time, the toothpaste in which the elbow is not raised higher than the hand holding the toothbrush flows down from the hand to the forearm, and further to the clothes such as pajamas worn by the person who is brushing the teeth. There is the inconvenience of soiling the clothes. In addition, since the white streak-like dirt of the toothpaste adheres to the aforementioned forearms where the toothpaste has flowed down, the hands and forearms must be washed with water or hot water to wash off the dirt after brushing the teeth. In fact, it is not uncommon for such inconveniences to make toothbrushing a nuisance.
