BACKGROUND OF THE INVENTION The present invention relates to a golf tee using a biodegradable plastic material as a molding material.

[0002]

2. Description of the Related Art Conventionally, a biodegradable plastic molded article using a biodegradable plastic material has been known.
Biodegradable plastic molded products are “degradable” plastics that degrade naturally even when disposed of underground or in the sea.
In other words, in a process of natural decomposition in the natural world, it is a high molecular compound that is converted into a low molecular weight compound by involving the metabolism of living organisms. Has also attracted attention.

However, conventional biodegradable plastic molded products have not been established for biodegradability test methods.
Even if they are actually disposed of in landfills, most of them do not spontaneously decompose and remain as they are over a long period of time. Present as a real problem. In addition, since biodegradable plastic materials are mostly natural polymers mainly composed of starch, such as potatoes, molded products are soft, and there is also a problem that hard molded products cannot be easily obtained. There was a difficulty in obtaining a practical golf tee.

[0004] The present invention has solved the problems existing in the prior art as described above, and by facilitating spontaneous decomposition and increasing the rigidity of a molded article, it is easy to insert the molded article into the ground. It is an object of the present invention to provide a golf tee capable of protecting the environment and simplifying maintenance.

[0005]

SUMMARY OF THE INVENTION A golf tee To (biodegradable plastic molded article T) according to the present invention is a biodegradable plastic material having liquid paraffin adhered to the surface thereof. Characterized in that it is formed by mixing particles of a crushed material M obtained by crushing hard seed hulls such as walnut shells and apricot seeds selected in the range described above. In this case, the amount of the pulverized material M is desirably selected in a range of approximately 5 to 30% by weight based on the biodegradable plastic material.

[0006]

According to the golf tee To of the present invention, since the crushed material M obtained by crushing hard seed hulls such as walnut husks is mixed in the biodegradable plastic P, the biodegradable plastic P having a slow natural decomposition rate is used. In addition to the reduction of the absolute usage, the physical state of the biodegradable plastic P becomes a continuum of a thin-walled portion due to the pulverized material M present therein, and the natural decomposition is promoted from the physical aspect. Moreover, the crushed material M
Uses naturally a plant constituent, so that the naturally decomposed crushed material M is naturalized as it is.

[0007] The particles of the pulverized material M are selected in the range of approximately 100 micrometer to 1 millimeter in diameter, and the amount of the pulverized material M is desirably in the range of approximately 5 to 30 weight percent based on the biodegradable plastic material. By this, good moldability in the molding process and good molding quality in the molded product are ensured.

Further, since hard seed hulls such as walnut husks, which are residues of processed vegetable products, can be used, the rigidity of the whole molded product can be easily increased, and the residues can be effectively used as resources. Furthermore, since the biodegradable plastic material having liquid paraffin adhered to the surface is used, when the crushed material M is mixed, the crushed material M adheres to the surface of the biodegradable plastic material and can be mixed more uniformly. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will now be described in detail with reference to the drawings.

(Materials and Amount Used) First, pulverized walnut shells M are added to a biodegradable plastic material (eg, “Matabee (trade name)” manufactured by Nippon Synthetic Chemical Industry Co., Ltd.) in a range of 1 to 80. Are mixed stepwise (1, 3, 5, 10, 20,...) At a ratio of each weight percent to prepare a plurality of types of molding materials. In addition, as a particle of the pulverized material M, a diameter range of about 100 μm to 1 mm is selected. The reason for selecting such a range is that if the particles of the pulverized material M are too small, they do not mix uniformly when mixed with the biodegradable plastic material. Is to be reduced.

(Molding Method) The biodegradable plastic material and the crushed material M of the walnut shell are uniformly mixed, and injection molding is performed using an injection molding machine. The molding conditions in this case are set according to the case of injection molding using a single biodegradable plastic material, and injection molding is performed in the same process. The mold used has a cavity in which the golf tee To shown in FIG. 2 can be molded.

Further, if necessary, liquid paraffin may be previously attached to the surface of the biodegradable plastic material (pellet). Thereby, when the crushed material M is mixed, the crushed material M adheres to the surface of the biodegradable plastic material, and can be mixed more uniformly.

(Molding Result) The golf tee To shown in FIG. 2 is obtained by completing the molding. In this case, as shown in FIG. 1, the pulverized material M of the walnut shell is formed as it is in the solidified biodegradable plastic P. According to the molding results, the amount of the pulverized material M was 5 to 3 with respect to the biodegradable plastic material.
Relatively good results were obtained in the ratio range of 0% by weight, in particular a ratio of around 15% by weight gave the best results.

In the case of a molded article made of only a biodegradable plastic material, the rigidity was low and it was difficult to insert the molded article into the ground. In the case of the molded article T), appropriate rigidity was obtained, and the molded article T) could be easily inserted into the ground. On the other hand, such a golf tee To
Decomposes spontaneously when left at a golf course after golf is completed. In particular, since the physical state of the biodegradable plastic P becomes a continuum of a thin portion due to the presence of the pulverized material M, spontaneous decomposition is promoted from a physical aspect. In addition, since the crushed material M is a constituent of a plant by nature, it is naturalized as it is. Therefore, environmental protection and maintenance of the golf course can be simplified.

In addition, similar results were obtained by using hard seed shells such as apricot species instead of walnut shells.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment,
The detailed configuration, method, and the like can be arbitrarily changed without departing from the gist of the present invention.

[0017]

As described above, the golf tee according to the present invention comprises a biodegradable plastic material having liquid paraffin adhered to its surface, and a walnut shell and apricot species selected in a diameter range of approximately 100 μm to 1 mm. Because the particles of the crushed material obtained by crushing the hard seed shell such as were molded and mixed,
It has the following remarkable effects.

In addition to reducing the absolute usage of the biodegradable plastic, the physical state of the biodegradable plastic becomes a continuum of thin-walled parts due to the pulverized material inside, and from the physical aspect, the physical state of natural decomposition Promotion can be aimed at.

Since the rigidity of the entire molded article can be easily increased, a golf tee that can be easily inserted into the ground can be realized, and environmental protection and maintenance of the golf course can be simplified.

[0020] Residues of processed plant products can be effectively used as resources. In addition, since the biodegradable plastic material having liquid paraffin adhered to the surface is used, when the pulverized material is mixed, the pulverized material adheres to the surface of the biodegradable plastic material and can be more uniformly mixed.
