Description

TECHNICAL FIELD The present invention relates to a toothbrush which is used in a disposable state, which is molded by a mold and is folded when used.

"Prior Art" Conventionally, there are various types of toothbrushes that are used in a disposable state, but in all of them, the handle part of an ordinary toothbrush is formed into a thin and small size.

Therefore, there are drawbacks in that manufacturing is time-consuming and costly, the entire volume is relatively large, a large storage space is required, and the transportation cost is high.

In addition, since the toothbrush has almost the same shape as an ordinary toothbrush, it is not interesting to use, and there is a drawback that it looks cheap.

"Object of the Invention" In view of the conventional drawbacks as described above, the present invention requires a small storage space, can reduce the transportation cost, and can be mass-produced at low cost by using a mold having a simple structure. It is to obtain a toothbrush that can be used without being seen by cheap items because it can be assembled and used.

"Means for Achieving the Object of the Present Invention" The present invention relates to a pair of toothbrush main bodies each having a thin width bent portion having a thin-walled bent portion that can be folded in two in the width dimension direction, and a pair of the toothbrushes. A thin central bent portion that connects the side surfaces on the rear end side of the main body in a foldable manner, and a substantially triangular pyramid shape integrally molded so as to project outward from both side surfaces on the front end side of the pair of toothbrush main bodies. It consisted of four brushes with brush bristles arranged in series so that the vertices of the triangles were alternately located on the top and bottom sides, and was molded into a card-like size with a synthetic resin material without using a slide core. It has a feature.

Further, the present invention has a pair of toothbrush main bodies each having a thin width bent portion that can be folded in two in the width dimension direction, and a pair of toothbrush main bodies each having a small width dimension, and the pair of toothbrush main bodies being folded on both sides on the rear end side. Arranged in series is a thin central bent portion that is operably connected and brush hairs that are integrally molded so as to project outward from both side surfaces on the tip end side of the pair of toothbrush bodies and that can be die-cut in the vertical direction. It is characterized in that it is made of a synthetic resin material without using a slide core.
