AI Technical Summary
The disposal of entire toothbrushes made from synthetic resin plastics contributes significantly to plastic waste, necessitating a solution to reduce plastic production and waste by allowing partial replacement of toothbrush components.
The toothbrush design incorporates holes in the neck and head with female screws, enabling the reuse of the grip by attaching a male-threaded grip to the neck, allowing only the brush and neck to be replaced.
This design reduces plastic waste by allowing the reuse of the grip, minimizing the need to discard the entire toothbrush and promoting sustainable toothbrush maintenance.

Abstract
Description
[Technical Field]
[0001] This invention is a toothbrush that separates the conventional single toothbrush into two. [Background technology]
[0002] Currently, when the bristles of commercially available toothbrushes wear out, the entire toothbrush is discarded and replaced with a new one. [Prior art documents] [Patent documents]
[0003] Summary of the Invention [Problem to be solved by the invention]
[0004] Traditionally, replacing a toothbrush involves discarding the entire toothbrush and purchasing a new one. Toothbrushes are usually made from synthetic resin plastics, and discarding toothbrushes is also discarding plastic, which has become a major social problem. This invention is intended to contribute to the reduction of plastic production and waste. The solution that the invention aims to solve is
[0005] In this design, holes are drilled in the head where the brush is located and in the neck, and a female screw is attached to the grip, which faces the neck. The male thread of this grip is screwed into the female thread of the neck, and the two are used as a single toothbrush. If you attach female threads of the same diameter and pitch to the necks of a wide variety of toothbrushes, you can use them as new toothbrushes by simply replacing the head and neck. The grip, which takes up a large portion of the entire toothbrush, is not disposed of and can be used almost permanently.
[0006] As mentioned above, when replacing a toothbrush, only the brush and neck need to be disposed of, eliminating the need to dispose of the plastic grip, which makes up a large portion of the toothbrush, and contributing to reducing plastic production and waste. [Brief explanation of the drawings]
[0007] [Figure 1] FIG. 1 is a perspective view of the present invention. [Figure 2] 1 is a perspective view showing an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION
[0008] Drill a hole in the cross section of the neck part (2) that connects to the toothbrush brush (1) and attach a female screw (4) to the inside of the hole. In addition, the grip part (3) has a male thread (5) on its cross section that matches the female thread on the neck part. By leaving the grip part intact, it is possible to replace a wide variety of brush parts. [Explanation of symbols]

Claims
[Claim 1] The toothbrush has a neck and grip that are separated and used as a single unit with the female screw on the neck and the male screw on the grip.
