Pet-bottle handle adapter for practicing self-defense technique

Abstract

To provide a handle adapter capable of safely practicing a self-defense technique by using a PET bottle having proper flexibility.SOLUTION: The present invention relates to a handle adapter comprising a joint portion (a) and a handle portion (b). The joint portion (a) has a screw type structure that can be attached to a cap portion of a PET bottle, and the handle portion (b) has a cylindrical shape having a diameter of about 2 to 3 cm and a total length of about 10 to 15 cm, and has a shape that can be firmly gripped by a user. Further, a vent hole is provided in a bottom part of the handle part, and the air in the PET bottle is released to the outside at the time of hitting, so that the PET bottle is recessed to alleviate the impact applied to the opponent. This enables safe training in self-defense.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a handle adapter that can be attached to the cap of a PET bottle from the viewpoint of recycling and reuse. [Background technology]

[0002] While recycling of PET bottles is widespread, there are limited ways to reuse them, especially the caps. [Prior art documents] [Non-patent literature]

[0004] To provide an object of the present invention to use a plastic bottle having a moderate softness as a training tool for self-defense techniques. [Means for solving the problem]

[0005] The present invention provides a handle adapter consisting of a joint (a) and a handle (b). The joint (a) has a screw-type structure similar to the inside of a plastic bottle cap, and can be attached to the plastic bottle. The handle (b) holds the plastic bottle attached at the joint (a). blade It acts as a handle when swinging the sword, and the user can hold it. Cylindrical, about 2-3 centimeters in diameter and 10-15 centimeters in length It has the shape of The bottom has a ventilation hole (1), which allows the air inside the plastic bottle to escape to the outside when striking an opponent in training, thereby mitigating the impact on the opponent.This allows the user to safely use a plastic bottle with moderate softness for self-defense practice. [Effects of the Invention]

[0006] According to the present invention, a plastic bottle can be used as a weapon such as a blade, allowing safe self-defense training. In addition, the reuse of plastic bottles is promoted. [Brief explanation of the drawings]

[0008] As shown in Figures 1 and 2, the handle adapter of the present invention consists of a joint (a) and a handle (b). The joint (a) has a screw-type structure similar to the inside of a plastic bottle cap. By screwing it onto the opening of a plastic bottle, it can be integrated with the plastic bottle. The handle part (b) is This handle is used for practicing self-defense by swinging a plastic bottle like a blade, and has a cylindrical shape with a diameter of about 2 to 3 centimeters and a total length of about 10 to 15 centimeters so that the user can hold it firmly. Furthermore, a ventilation hole (1) is provided at the bottom of the handle (b), so that when the plastic bottle is struck against an opponent during training, the air inside the bottle is released to the outside, intentionally denting the bottle and mitigating the impact on the opponent. This allows the user to: Plastic bottles are moderately soft and can be safely used for self-defense practice.
