Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a toothbrush, and more particularly to a toothbrush suitable for people with sensitive gums.

0002

[Conventional technology]

Toothbrushes that have been widely used in the past have a brush part on the tip of the handle. It has been known. In addition, as a method of cleaning your teeth, we recommend using a rotary treatment to maintain healthy gums and prevent tooth decay. The ring method, that is, the method of forcefully moving the toothbrush in the vertical direction, and the Buffers performed after disease surgery, crown restoration, implant surgery (artificial tooth root planting surgery), etc. The toothbrush method, ie, the method of moving the toothbrush in a small and gentle manner in the lateral direction, is known.

0003

[Problem that the idea aims to solve]

Traditional toothbrushes have a handle that allows you to grip the handle firmly with your fingers. Because it can apply force to the brush part, it prevents healthy gums and cavities in the gums. Suitable for preventive rolling, however, traditional tooth brushing With a brush, force is easily applied to the brush part, and the balance of force applied to the brush part that touches the gums is It becomes difficult to adjust the lance and can easily damage the gums, so if periodontal disease is progressing or In the oral cavity after dental surgery, crown restoration, implant surgery (artificial tooth root planting surgery), etc. The problem is that it is not suitable for cleaning. The purpose of this invention is to provide a toothbrush that solves these conventional problems. Ru.

[Means to solve the problem]

The inventor of this invention softens the force of the brush part that hits the gums for people with weak gums. After careful consideration, we achieved the above objective by weakening the grip force on the handle. I found out that it is possible. The toothbrush of the present invention was created based on this knowledge, and the toothbrush of the present invention has a In a toothbrush equipped with a brush part, a grip part is formed by protruding a convex part from the rear end of the handle. In addition to making the brush part and grip part independent, there is a The grip is characterized by forming an intermediate portion which is curved in the direction and has a longer length than the grip portion. Furthermore, even if the grip part is configured with an uneven part formed on the opposite side of the projecting direction of the protruding part, good. Further, the intermediate portion may be formed to be more elongated than the grip portion.

[0005]

[Effect]

Grip the grip part with your fingers and apply the brush part to your gums. At this time, at the rear end of the handle The grip part is formed independently and short by the convex part, so it is easy to grasp the grip part. The force applied is small, and the brush part is separated from the grip part through the curved middle part. This reduces the pressure exerted on the gums by the brush. In addition, if the grip part has an uneven part on the opposite side to the protruding direction of the protruding part, the grip part can be The tap part can only be gripped with the fingertips. Also, if the middle part is made more elongated than the grip part, the force transmitted to the brush part will be further increased. Decrease.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show one embodiment of the present invention, in which 1 is the handle, and 2 is the tip side of the handle 1. 2 shows a brush portion in which a plurality of bristles 3 are implanted. In this embodiment, a convex portion 4 is protruded near the rear end of the handle 1, and the handle 1 is located on the rear end side of the convex portion 4. A flat grip part 5 is formed in a part of the brush part 1 and the grip part 5. An intermediate portion curved in a direction opposite to the direction of the tips of the bristles 3 implanted in the brush portion 1 in between. 6 was formed. Further, the intermediate portion 6 is made narrower and thinner than the grip portion 5. It was formed into an elongated shape. With this configuration, the grip part 5 can be attached to a part of the handle 1 by the convex part 4. Because it is short and independently formed, there is no place to grip the entire handle like a conventional toothbrush. When gripping the grip part 5, the convex part ensures that the fingers are firmly placed on the rear end of the handle. Since it is possible to grip only the portion of the toothbrush, the gripping force of the toothbrush can be reduced, and the brush can be The force transmitted to the part is small. If the grip part 5 is formed into a flat shape as shown in the illustrated example, the grip part 5 can be gripped. When doing so, do not grip the grip part 5 with your fingers, but grip the grip part 5 with your fingertips. Therefore, the gripping force of the grip part 5 can be made smaller than when gripping. Ru. In addition, in the figure, 7 is a tuft hole for the bristles 3 drilled in the brush part 2, and 8 is a hole penetrated through the grip part 5. This shows the hole for hooking.

[0007] 5 and 6 show other embodiments of the present invention, in which the grip portion 5, parallel to the width direction of the grip part 5 on the opposite side of the protruding direction of the convex part 4. In this embodiment, a concavo-convex portion 9 is formed. It should be noted that the components are the same as those in the embodiment shown in FIGS. 1 to 4, and no special explanation is required. Components are given the same reference numerals as in the previous embodiment, and their explanations are omitted. Since the grip portion 5 is provided with the uneven portion 9 in this way, the grip portion 5 can be When gripping, simply place your fingertips on the uneven portion 9 to ensure a secure and easy grip. Ru.

[0008] 7 and 8 show a modification of the present invention, in which the brush part 2 is 1, that is, the brush portion 2 is provided in a T-shape on the tip side of the handle 1. This is a toothbrush designed primarily for front teeth. It should be noted that the components are the same as those in the embodiment shown in FIGS. 1 to 4, and no special explanation is required. Components are given the same reference numerals as in the previous embodiment, and their explanations are omitted.

[0009] 9 and 10 show other variations of the present invention, in which the grip An uneven portion 9 is formed on the grip portion 5 on the opposite side of the projecting direction of the convex portion 4 of the portion 5, and Place the brush part 2 perpendicularly to the direction of the handle 1, that is, place the brush part 2 on the tip side of the handle 1. It is provided in a T-shape, and is mainly used for front teeth as in the embodiments shown in Figs. 7 and 8. This is a toothbrush. It should be noted that the components are the same as those in the embodiment shown in FIGS. 1 to 4, and no special explanation is required. Components are given the same reference numerals as in the previous embodiment, and their explanations are omitted.

[Effect of the idea]

According to the present invention, the grip part is short and independent at the rear end of the handle due to the convex part. When grasped with the fingers of the hand, the protruding protrusion makes the handle look like a conventional toothbrush. Since the whole part is not grasped, the force to grasp the grip part is reduced, and the brush part Because only a small amount of force is transmitted to the The length between the brush part and the grip part can be used to clean the grip part. The middle part is longer and curved than the middle part, so when applying the brush part to the gums, can be applied securely to a predetermined location by pressing due to the curvature of the middle part. have an effect. Also, if the grip part is configured with an uneven part on the opposite side of the protruding direction of the convex part, , the grip part can be gripped reliably and easily simply by placing a finger on the uneven part, and , the toothbrush can be reliably moved laterally. In addition, if the middle part is formed to be more elongated than the grip part, the gripping force on the grip part can be increased. Because it can be made smaller, the transmission of force to the brush part can be further reduced. It has the effect that it can.
