Abstract

A rubber-nylon-mixture bristle toothbrush which does not injure teeth nor gums and can perform effective tooth-brushing and gum-massaging at the same time, and which comprises a toothbrush head integrally formed by rubber triangular or quadrangular pyramidal bristles and nylon bristles and a handle with a serrated irregular connection section provided between the head and the handle.

Description

Details

Mixed toothbrush of rubber and nylon bristles

The present invention relates to the shape of a flocking on a brush surface and the shape of a joint between a brush surface and a handle in a toothbrush. Background art

Conventional toothbrush heads are made of nap hair, pig hair, or PBT hair, each of which has a columnar shape. There was also a toothbrush head made of rubber, but it was easy to pull out with a plug-in type, and it was fixed with an adhesive.

For this reason, brushing with the hardness of the material, the sharp shape, and the hardness of the plastic with the handle could damage the teeth and gums. Some toothbrush heads are made of rubber, but they are plug-in type, easy to pull out, and solve the problem of fixed parts with adhesive, so you can massage your gums while brushing your teeth at the same time They try to provide a toothbrush. Disclosure of the invention

The mixed toothbrush of rubber and nylon bristles of the present invention uses rubber in the toothbrush head (1) to form a round hole in the center where nylon bristles can be planted in order to solve the above-mentioned problems. At the tip (2), make a round groove to plant nylon hair. Next, a rubber head is inserted into the handle without Nylon hair (Fig. 3). Then implant the hair into the rubber-covered toothbrush head. This is a completed perspective view (Fig. 4). The present invention is a mixed toothbrush of rubber and nylon bristles having the above configuration.

BRIEF DESCRIPTION OF THE FIGURES

(A) Front view of the mixed toothbrush of rubber and nylon bristles of the present invention (Fig. 1

) Is disassembled into the state of the exploded view (Fig. 2), and if the rubber head of the drawing (1) is inserted into the plastic resin handle of (2), the state will be without nylon hair (Fig. 3).

(□) When nylon wool is planted in this (Fig. 3), it becomes a perspective view (Fig. 4).

Since the mixed toothbrush of rubber and nylon bristles of the present invention has the above structure, the following excellent effects can be expected.

1. The shape of the rubber flock is triangular or quadrangular pyramid. By planting the bristles in the center, there is no danger of damaging the teeth and gums as with a conventional bristles toothbrush. Work) and face (wiping) tooth brushing and gum massage can be performed simultaneously.

2. The use of rubber and nylon bristles for the toothbrush head flocking material allows simultaneous brushing and gum massage, which can be expected to have a significant effect on periodontal disease prevention.

3. By making the shape of the joint between the rubber and the handle into a saw-tooth pattern, the joint can be firmly joined without using an adhesive at the joint, and a hygienic effect can be expected.
