Abstract

PURPOSE:To enable the raking of deposits on teeth and the brushing of the teeth even with the shank part of a bristle by twisting two or three of several tens of bristles in one tuft hole embedded in a block handle for forming a single rope-like bristle. CONSTITUTION:The toothbrush in the title has twisted bristles, and the projected part 2 of the bristles is always in contact with a certain tooth surface in any warped condition, though the extent of the contact depends upon the warped condition. Consequently, a deposit on tooth surface is raked with the spiral projection of the bristles and teeth are brushed. In the conventional tooth. brush, a bristle tends to lie down, even when subjected to a small force, and tooth brushing cannot be well done. In the case of the toothbrush in the title, teeth can be brushed even when the bristle lies down due to a strong force. In addition, the area of the projected part 2 is substantially larger than the tip area of the bristle of the conventional toothbrush. Furthermore, a strong force for brushing teeth acts in such a way that a bristle presses another bristle, and the force acts on the teeth surface, thereby preventing the loss of the force and ensuring clean tooth brushing in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a toothbrush that has the ability to remove and polish tooth surface deposits even on the chest of the toothbrush bristles.

Prior Art Conventional toothbrush bristles are all straight, although there are differences in how thin and thick they are, and no modifications have been made to the cross section of the toothbrush bristles or the relationship between toothbrush bristles. Therefore,
Whether your toothbrush has hard or soft bristles, brushing your teeth is done with the bristles at the end of the brush.

Furthermore, if too much force was applied to the toothbrush, the toothbrush bristles would become flattened, and the body of the toothbrush bristles simply stroked the surface of the teeth, without any polishing effect.

Problems to be Solved by the Invention The present invention forms a kind of convex part on the body of the toothbrush bristles, which conventionally had a straight and round cross section, and uses the convex part to remove deposits on the tooth surface. The challenge is to remove the imperfections and polish them.

Means for Solving the Problem (1) The conventional round cross section of the toothbrush bristles is changed to a square cross section, and corners are provided on the body of the toothbrush bristles.

If you use this toothbrush with only this corner and brush your teeth, you will only be stroking the surface of your teeth like you would with a conventional toothbrush.

In the present invention, by twisting the toothbrush bristles having a rectangular cross section, it is possible to form the convex portion referred to in the above-mentioned problem.

Means (2) Conventionally, toothbrush bristles are embedded in bundles of several dozen in one hole with a diameter of 1% to 2% in a toothbrush handle. The present invention twists two or three toothbrush bristles, which are several tens of times the number of toothbrush bristles in one hole embedded in the toothbrush handle, into one rope-like bristle.

It is well known that the surface of a rope is not flat, and this makes it possible to form the convex portion mentioned above.

Function To explain the function of the toothbrush of the present invention, when using this toothbrush and brushing your teeth with as little force as possible, it is no different from a conventional toothbrush, and you will be brushing only with the bristles, but a little force is applied to the toothbrush. In this case, the toothbrush bristles are warped, and the ratio of the body of the toothbrush that touches the surface of the teeth is thick (regardless of whether the cross section of Naruuko's poetry brush bristles is square or round, if they are square, they will be twisted) If the brush is round, it will simply stroke the surface of the tooth unless two or more bristles are twisted together into a rope.

Since the toothbrush of the present invention has twisted toothbrush bristles, the convex part of the toothbrush bristles always touches somewhere on the surface of the tooth, regardless of the degree of warpage, although it depends on the degree of warpage of the toothbrush bristles. The spiral protrusions are not parallel to the direction in which the toothbrush is moved, so even if the toothbrush bristles move straight in the longitudinal direction of the fallen bristles, the helical protrusions will not chip away the deposits on the tooth surface. This means that your teeth will be brushed.

This is similar to placing a thin bolt with just a gentle thread on the surface of the teeth, and moving it in the longitudinal direction of the bolt will cause the threads to chip off the surface of the teeth.

Effects With conventional toothbrushes, if you apply a little force, the bristles will fall off, making it difficult to brush your teeth, but with the toothbrush of the present invention, you can brush your teeth even if you apply too much force and the bristles fall off. The area of the convex part provided on the body of the toothbrush of the present invention is by far the largest, and even when brushing with even more force,
The force is applied to the surface of the teeth by the brush bristles pressing down on the bristles, so the force is not wasted, and a toothbrush that can clean the teeth in a short time can be provided.

In addition, when brushing the back side of the teeth, if you apply a little force to the toothbrush of the present invention and roll the toothbrush, the body and tips of the toothbrush bristles will come into contact with an extremely large amount, compared to conventional toothbrushes. It has an incredible effect.

The toothbrush bristles of the present invention can also be used for car wash brushes, scrubbers, etc.

Similar to the toothbrush of the present invention, it can be expected to have an even faster cleaning effect.
