Description

  The present invention reduces the damage to teeth and gums when brushing teeth, and steadily brushes teeth one by one to reliably remove plaque between teeth. Is related to the technology.

Conventionally, a toothbrush mainly focusing on easy gripping has been mainly used, and the handle portion of the toothbrush is long and a finger stop portion is formed so that force is applied, and it has been devised so as not to slip.
By tightening and brushing the handle of the toothbrush handle, force is applied to the finger stop, resulting in excessive force being applied to the tip of the toothbrush, and repeating this action every day will gradually damage the teeth and gums. It was a situation.

The use of a conventional toothbrush with a long handle has the following problems.
(1) Unintentionally grasping and polishing the handle portion of the toothbrush resulted in excessive force being applied to the tip of the toothbrush, resulting in damage to the teeth and gums.
(2) The stroke to move the toothbrush was increased, and it was in a situation where it was not possible to sufficiently remove the plaque sandwiched between the teeth or between the teeth and gums by simply brushing the tooth surface. .
(3) Furthermore, because of the structure in which the hand is clamped, it is difficult for the person who is polishing to be aware of the problem of item 2 above.
As one means for solving these problems, Japanese Patent Application Laid-Open No. 2008-161616 is disclosed. However, in the structure of the handle part of the toothbrush, the handle part to be gripped with the middle finger or ring finger is extremely thin compared to the part to be gripped with the thumb or forefinger, and is 8 mm or less in the shape of a round bar, and firmly gripped with the little finger. Since a part of the handle, which is characterized by a shape that is too short to be able to be used, is a very thin and short toothbrush, there are the following problems.
(1) There is a possibility that an event similar to the situation in which a long toothbrush handle is used is generated due to the force applied to the middle finger or the ring finger.
(2) The stroke of moving the toothbrush unconsciously becomes large, and there is a possibility that the plaque sandwiched between the teeth or between the teeth and the gums cannot be sufficiently removed by simply brushing the tooth surface. It was.

  This application was devised to prevent this. (1) The handle part of the toothbrush is shorter than a normal toothbrush. Basically, the handle is supported by the thumb and forefinger, and the middle finger is supported as needed. (2) Support with the thumb and forefinger, and if necessary, slide the part to assist with the middle finger in the longitudinal direction of the handle, (3) Basically support the handle with the thumb and index finger, If necessary, manufacture the skeleton with a hard material such as plastic so that the sliding part that assists with the middle finger is not crushed by the force of the finger, and slide it smoothly in the longitudinal direction of the handle, (4) Basically, the cross-sectional outer shape of the sliding part that supports the handle with the thumb and index finger and assists with the middle finger as necessary is basically rectangular or elliptical, and the outer skin surface is made of a soft material such as rubber, and ▲ 5 ▼ Basically, handle the thumb and the index In support, and it makes it possible divided into two sliding parts to assist with the middle finger to the dorsal and ventral direction of the handle as necessary. Further, the sliding distance of the sliding portion is close to the lateral length of one tooth and is about 3 to 6 mm.

According to the present invention, the following effects can be obtained.
(1) Basically, the handle is supported by the thumb and forefinger, and the handle of the toothbrush is supported with the force of the middle finger as needed, preventing excessive force from being applied to the tip of the toothbrush. And can reduce the damage to the gums.
(2) Basically, the handle is supported by the thumb and forefinger, and if necessary, the part that assists with the middle finger is slid in the longitudinal direction of the handle, and the sliding distance of the sliding part is the length of one tooth. Because it is approximately 3 to 6 mm, which is close to the thickness, a force that consciously reduces the stroke of moving the toothbrush works, and since it becomes a stroke every minute, plaque sandwiched between teeth or between teeth and gums Can be sufficiently removed.
(3) Basically, the handle is supported by the thumb and forefinger, and the skeleton of the sliding part, which is supported by the middle finger as needed, is made of a hard material such as plastic, so it slides smoothly in the longitudinal direction of the handle. Can do.
(4) Basically, the cross-sectional outer shape of the sliding part, which is supported by the thumb and forefinger and assists with the middle finger as required, is basically rectangular or elliptical, and the outer skin surface is made of a soft material such as rubber. The sliding part can be easily supported by the thumb and index finger, and the angle of the toothbrush can be easily changed according to the angles of the gums and teeth.
(5) Basically the handle is supported by the thumb and forefinger, and if necessary, the sliding part that assists with the middle finger can be divided into two in the back and abdomen directions of the handle. Convenient for removing and cleaning sliding parts.
(6) By using the toothbrush of the present application, it is possible to acquire a habit of brushing in small steps with a small force, and to make the user naturally aware of how to brush teeth correctly.
When you go to a dentist, you are instructed as a correct way to brush your teeth: “Press your toothbrush lightly with your fingers and brush each tooth in small increments.” Since the toothbrush has a long handle, many people inevitably hold it with their hands and polish it strongly by putting effort into the finger stop. In the future, it will be necessary to spread the correct way of brushing teeth by spreading the toothbrush of the present application.

  Hereinafter, the best mode of the fingertip toothbrush of the present invention will be described with reference to the drawings.
