Abstract

PURPOSE:To provide a sharp-edged tool which decomposes naturally after disposal and does not ill influence the terrestrial environment. CONSTITUTION:The shank 2 of a T-form razor 1 includes a grip 2a and a support 2b, and a head 3 is supported removably at the tip of the support 2b. The head 3 retains a lower edge 5 and an upper edge 7. The shank 2 is formed in a single piece molding from biodegradating compound prepared by adding a certain amount of calcium carbonate to biodegradating polymer such as polyhydroxy butyric acid. Therefore, the shank 2 is biodegradated in the soil after disposal and does not ill influence the terrestrial environment.

[Problems to be Solved by the Invention] Nowadays, in the era of mass consumption, a large amount of waste is becoming a social problem. In particular,
The amount of garbage generated in metropolitan areas exceeds its incineration capacity, and the current situation is that the landfill is overwhelming the point of waste disposal. On the other hand, the influence of various wastes on the global environment has come to the fore, and it is desired to develop products that do not pollute the global environment even after disposal.

Regarding the conventional razor, the metal blade is gradually rusted in the soil after disposal and gradually returned to the natural world. On the other hand, the frame body of the razor head and the handle of the razor, which are made of polypropylene, are hardly decomposed in the soil and are not reduced in a form compatible with the natural material circulation. From a long-term perspective, this contributes to pollution of the global environment and depletion of resources.

Since the gripping part and the sheath of the ware are made of the biodegradable composition, when they are buried in the soil, the gripping part and the sheath are gradually biodegraded in the soil. On the other hand, the blade body is gradually oxidized in the soil to generate rust and decompose. Therefore, even if the ware is directly landfilled and discarded, almost all parts that make up the ware are returned in a form compatible with the natural material circulation.

Examples of biodegradable polymers include polyhydroxybutyrate (abbreviated as PHB) and polyhydroxyvalerate (abbreviated as PHV).
Etc. These polymers are obtained by fermenting carbohydrates such as grains, and have thermoplasticity and easy injection molding. When molded articles made of these polymers are left in the soil, the molded articles are biodegraded at a rate of about 5 to 20 mm per year due to the action of bacteria and the like. Biodegradation products do not cause harm to the ecosystem. The molecular formulas of PHB and PHV are as follows.

These additives improve the strength of the molded article without impairing the biodegradable properties of the biodegradable composition as compared with the case where the biodegradable polymer is used alone.
