DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables smooth brushing by moving brush bristles smoothly in the oral cavity, and has a soft touch on the gums and mucous membranes in the oral cavity. The above relates to a toothbrush devised particularly to attract the interest of infants and the like.

2. Description of the Related Art Conventionally, toothbrushes generally have a structure in which a bar-shaped handle is formed with a flat-shaped flocked portion at the tip and a bristle of animal hair or synthetic fiber is planted in the flocked portion. Yes, it is always used as a daily necessity for men and women of all ages. In addition, recently, in order to enhance the brushing effect, the flat portion which is a flocked portion is reduced to half or less, so that the brush bristles on the back teeth and the back side of the teeth are easy to hit, and the upper surface of the brush bristles is formed in a mountain shape, and the groove and the teeth of the teeth are formed. There have been developed toothbrushes in which the bristle tips appropriately contact the interstices, toothbrushes in which brush bristles are composed of two different types of bristles, and the like.

[0003]

However, all of the conventional toothbrushes have a structure in which the bristle portion is formed in a flat plate shape and the bristles are planted on the upper surface of the flat plate portion. Both become straight in the left-right or front-back direction, and the tip of the bristles sufficiently hits the teeth due to the turning of the wrist, etc., and the remaining residue attached to the teeth and between the teeth can be removed neatly. I needed to. In other words, when brushing your teeth, you will not be able to obtain a great effect unless you have the correct brush bristle moving technique, and there are not many people who can actually brush their teeth well. Many people just press hard, so that the degree of tooth decay may be increased or the gums may be damaged, and the brush ends up quickly and the toothbrush itself becomes useless I often did. The practice of brushing teeth during childhood is very important, but brushing with brush bristles planted only on one side is extremely difficult for infants, and mothers etc. usually apply finishing. By having the mouth open wide, the child would dislike it and lead to dislike of tooth brushing, and polite brushing would create ironic dislike. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has an advantage that the brush bristles can smoothly contact the teeth and between the teeth and promote effective brushing. An object of the present invention is to provide a toothbrush that is less likely to damage the mucous membrane, can prolong the life of the toothbrush itself, and is useful for infants and children to brush their teeth.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional side view.

In the drawings, reference numeral 1 denotes a toothbrush main body, which is constituted by a handle 2 and brush bristles 3 and provides not only a functional surface having a high brushing effect but also an aesthetically pleasing appearance. It is a toothbrush that can be used by children (especially toddlers and children) in a fun way and allows them to practice brushing.

The handle 2 is provided with a flocked portion 2a at a tip portion thereof, and by forming the flocked portion 2 in a spherical shape, the overall state of the brush bristles 3 is adjusted to a spherical shape. This makes it possible to provide a toothbrush that is easy to brush. In addition, the shape of the flocking portion 2 may be an elliptical spherical shape instead of a circular spherical shape, and is not particularly limited.
The rod body of the handle 2 may be circular, rectangular, or polygonal in cross section and should not be specified. However, the brush bristles 3 are oriented in all directions, and there is no so-called front face, so any brush bristles What is necessary is just to consider the shape of the grip handle 2 so that even three parts can contact a tooth.

The brush bristles 3 are radially planted in the flocked portion 2a, and a bundle of about 20 to 30 bristles is implanted from one place. By providing the brush bristles at a number of locations on the surface of the flocked portion 2a, the brush bristles are provided in a spherical shape as a whole. Needless to say, the length, thickness, hardness, type, and the like of the brush bristles 3 are different depending on the target age and preference, and it is sufficient to provide the user with optimal brush bristles. It should be noted that the thickness of the toothbrush may be reduced to about one half of that of the conventional product and the contact with the gums and the oral mucosa may be made softer (softer).

Therefore, if the brush bristles 3 are radially implanted and have a spherical shape, the brush bristles can be smoothly moved in the teeth or in the oral cavity by a simple manual operation of the grip handle 2 and each brush bristles can be smoothly moved. The tip of the hair reaches all corners throughout, and even if it is a back tooth, you can expect a certain brushing, and you can do a polite and speedy brushing. In addition, unlike the conventional case, the bristle tip does not immediately fall asleep, and it can be said that the solid brushing effect is continued for a long period of time. Furthermore, since the contact with the gums and the like is soft, the inside of the oral cavity is not damaged, so that gentle brushing is possible not only for ordinary people but also especially for those with alveolar pyorrhea or weak inside the oral cavity. Thus, a highly usable toothbrush can be supplied. or,
Speaking particularly about the habit of brushing teeth for infants and children, first of all, it is interesting because it has an unconventional original shape, and then it is easy and speedy to brush back teeth. It is most suitable for habit of brushing teeth because it finishes brushing before getting tired and the softness of the tip of the bristles does not cause the parent to press hard as in the past so that it does not hurt.
