Biodegradable prefabricated eco-friendly toothbrush

The present invention relates to a biodegradable prefabricated eco-friendly toothbrush.

More specifically, the present invention relates to a biodegradable prefabricated eco-friendly toothbrush that can be disposed of by using the toothbrush head in the handle part at home, in a hotel, or outdoors.

The present invention is to be composed of a head portion that is assembled by fitting to the handle portion, the handle portion and the head portion is a biodegradable composition or bio-containing polyester-based polymers, polylactic acid, physical properties, lubricants, inorganic abrasives, etc. It relates to a biodegradable prefabricated eco-friendly toothbrush composed of a resin composition using a mass to prevent environmental pollution during disposal, easy to assemble and separate, and to selectively replace and use multiple heads.

In addition, the present invention relates to a biodegradable prefabricated eco-friendly toothbrush that is coated with a toothpaste on the filament of the head portion, and does not need to be provided with a separate toothpaste.

In general, a toothbrush is composed of a head portion provided with a bristle and a handle portion integrally molded or assembled with the head portion.

Conventionally, such a toothbrush is formed of a general synthetic resin material (for example, polyethylene, polypropylene, nylon, etc.) for both the head part and the handle part, thereby contaminating the environment when they are discarded, and there is a problem that disposal is difficult. In other words, these general synthetic resins take more than 100 to 200 years to be completely decomposed upon landfill, and produce various environmental problems such as environmental hormones, toxic and harmful substances when incinerated, and environmental treatment costs when disposed of.

In order to improve this, in Korean Utility Model Registration No. 20-0354838 (hereinafter referred to as'prior art'), a part of the brush in the head part is detachable from the head part, and when the brush is damaged, other parts are used as they are and the damaged brush Since the bay can be reused by replacing it with a new brush, it is possible to significantly reduce the amount of hazardous waste and to reduce the purchase cost compared to purchasing the entire toothbrush, thereby solving some of the previous problems.

However, such a toothbrush is not a fundamental solution to the burden of environmental pollution due to disposal.

Accordingly, the present applicant has developed a toothbrush configured to enable the head portion to be separated from the handle portion, and molded of a degradable material to facilitate disposal.
