Description

Toothpaste All-in-one Toothbrush}

The present invention relates to a toothpaste-integrated toothbrush.

A toothbrush is a tool that cleans teeth to remove food debris, plaque, and harmful bacteria, which are the main causes of gum disease and tooth decay.

It is stored in the bristles planted in the toothbrush and the deformable tube body so that it can be squeezed and used as needed, and the toothpaste containing ingredients such as fluorine and abrasive is used to remove the debris remaining between the teeth after eating. Of course, it removes various impurities formed on teeth and gums to make teeth and gums healthy and refresh the mouth.

In this toothbrush, bristles are planted on a head member at the front end of the toothbrush handle, and a handle portion and a neck portion are formed integrally with the head member in the longitudinal direction so that teeth can be cleaned by holding the handle portion by hand.

In addition, the bristles of the bristles are made of nylon or the like to form a thin and long constant section, and are planted in an upward direction from the upper surface of the head member.

Therefore, after squeezing and applying a certain amount of toothpaste to the bristles while holding the handle of the toothbrush, while the bristles are in contact with the teeth, apply appropriate force to the handle to move the toothbrush up and down and left and right to reduce friction between the bristles and the teeth. This is to clean the plaque and food debris stuck on the surface of the teeth.

However, if the user of the toothbrush is an ordinary infant or child, they do not like to brush their teeth, so there is a need to induce their brushing habit by arousing their curiosity. Therefore, most toothbrushes simply have various decorations on the handle, but the toothbrushes with decorations as described above quickly become boring over time, and the function of inducing brushing habits is not high.
