Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a tee used for golf, more specifically, a tee that is discarded outdoors is naturally decomposed to be harmless, and insects,
The present invention relates to a biodegradable and edible golf tee which is used as a feed for birds and small animals and a method for producing the golf tee.

[0002]

2. Description of the Related Art Conventionally, golf tees have been made of wood, but plastics have become the mainstream in recent years because they use forest resources and are relatively expensive. However, since the tee discarded at the golf course not only harms the environment but also damages the lawn mower, recently, a soil-molded one has been proposed in order to eliminate pollution.

[0003]

[Problems to be Solved by the Invention] The earthy tee, which appeared in place of the plastic tee for the purpose of eliminating pollution, is decomposed and returned to the soil naturally when it is disposed of at the golf course. There is almost no problem as dust that destroys the environment, but not only is it heavy and inconvenient to carry, but it also has the drawback of breaking during carrying because it lacks rigidity. Furthermore, since it lacks rigidity and elasticity, it breaks each time it is used, and a large number of tees are required, which is disadvantageous in terms of cost for the user.

The present invention not only has appropriate rigidity and elasticity and can be repeatedly used, but even when it is discarded, it is not only naturally decomposed by microorganisms in the soil but also more positively. The aim is to provide a golf tee that can be used as feed for small animals. It is another object of the present invention to provide a golf tee that is inexpensive and can be mass-produced by using plastic processing technology and is free of pollution.

[0005]

The invention according to claim 1 is a cured molded article of a biodegradable resin composition containing gluten and a hydrophilic plasticizer composed of nontoxic polyhydric alcohols as main components. Is used to provide a golf tee that achieves the above object. In the first place, gluten is a protein contained in wheat flour, which is edible, and when it is swollen with water, it has appropriate tackiness and elasticity, and when heated, it solidifies and solidifies. Further, gluten is usually commercially available as a powder. However, since it has no plasticity, it cannot be plastically molded. Therefore, when gluten is mixed with a hydrophilic plasticizer made of non-toxic polyhydric alcohols and kneaded with a stirrer, the gluten is plasticized and plastic molding becomes possible.

Therefore, polyalcohol which is non-toxic to gluten
If a biodegradable resin composition obtained by adding a hydrophilic plasticizer made of a rubber is injection-molded or compression-molded using a mold for manufacturing a golf tee, it is possible to produce a tee that can withstand practical use. .. Hydrophilic plasticizers composed of non-toxic polyhydric alcohols include glycerin and polyethylene glycol.
And sorbitol. Moreover, since polyhydric alcohols such as glycerin, polyethylene glycol and sorbitol can be used as plasticizers and are non-toxic and edible, they are biodegradable mainly containing gluten and this hydrophilic plasticizer. Molded articles of the resin composition are also nontoxic and edible. However, since this product is rather heavy and lacks rigidity, it is preferable to add an appropriate extender. However, according to the present invention, when the Tay after use is naturally decomposed and disappears, the Tay left outdoors is
We also expect small animals such as birds and squirrels to eat and clean them, so it is necessary to select a bulking agent from materials that feed small animals such as birds and squirrels. At the same time, it would be most desirable if it could achieve other purposes of reducing weight and increasing rigidity.

As a result of examining various materials from this viewpoint,
It has been found that a dry powder of vegetable fiber is most suitable for this purpose. Since the dry powder of vegetable fiber contains many pores, it has a low specific gravity and can be used as a lightweight agent, and since it is fibrous, it can enhance the rigidity of the molded product. Specific examples thereof include dry powder such as paddy pattern, straw, starch meal, and soybean meal meal. Since paddy patterns and straws have many pores and many fibrous materials, they are particularly suitable for the role as a lightweight agent and a rigidity-imparting agent. Starch meal and soybean squeezed meal, in particular, contain a large amount of starch, proteins and the like, and are therefore useful in enhancing the effect of promoting edibility. Therefore, it is preferable to use these materials alone or in combination according to the purpose.

That is, the method for manufacturing a golf tee according to the invention of claim 4 is characterized in that a dry powder of vegetable fiber is used as the edible extender. Further, in order to produce such a golf tee, the invention of claim 2 further comprises a hydrophilic plasticizer made of polyvalent alcohol which is non-toxic to gluten and, if necessary, an edible extender and the like. In addition, the present invention is characterized in that the biodegradable resin composition obtained by stirring and kneading is molded using a molding die for a golf tee. In addition, other extenders, plasticizers, mold release agents, aggregates, pigments, dyes, seasonings, attractants, flavors and the like can be added within a range that does not impair biodegradability and edibility. In particular, if a seasoning, an attractant, and a fragrance are used that are preferred by birds and small animals, the cleaning effect can be further improved.

Further, in order to obtain the required physical properties, it is preferable to limit the mixing ratio of the raw materials of the biodegradable resin composition. That is, in the invention of claim 3, the blending ratio in the biodegradable resin composition is set to the gluten powder 100.
It is characterized by using 15 to 40 parts by weight of a hydrophilic plasticizer composed of non-toxic polyhydric alcohols and 0 to 40 parts by weight of an extender. When the hydrophilic plasticizer exceeds 40 parts by weight, it is too soft to be a product as a taste.
On the other hand, if the amount is less than 15 parts by weight, plasticization is insufficient and plastic working cannot be performed. As described above, the molded product can be used as a tee without adding the filler, but it is better to add the filler up to 40 parts by weight in order to further reduce the weight, the rigidity, and the edibility. However, it is not preferable to add more than 40 parts by weight because the strength of the molded product becomes weak. That is, if the amount of the filler exceeds 40 parts by weight, molding cannot be performed unless another binder is added in addition to gluten.

For kneading these materials, a mixer is used for 2 to 10 minutes. At this time, it is not particularly necessary to heat. Molding is performed by compression molding or injection molding using a Tay molding die. In the case of compression molding, the mold is about 11
It is preheated to 0 to 160 ° C., the material is filled in a mold, and then compression molding is performed at 30 Kg / square cm to 180 Kg / square cm. In the case of injection molding, the temperature of the molding machine is 150 ~
It is heated to 180 ° C. to increase the fluidity of the material, and the material is injected from the nozzle into the mold. Further, in the above temperature and pressure ranges, the molding time is preferably in the range of 2 minutes to 10 minutes. If it is shorter than 2 minutes, the curing will not be complete and the product will be uneven. Further, even if it is longer than 10 minutes, it does not affect the quality of the product so much and it becomes uneconomical.

Further, since the Tay produced in this manner is relatively poor in water resistance, it is preferable to apply water resistance as a post-treatment. For water resistance treatment, the most suitable method is to immerse the tee in a solution of styrene resin, urethane-vinyl resin, ethylene vinyl acetate resin, etc., or to coat by coating or spraying a solution of these resins onto the tee. It's easy.

[0012]

The biodegradable resin composition of the present invention comprising gluten and a hydrophilic plasticizer comprising a non-toxic polyvalent alcohol can be molded by compression molding or injection molding. Since this molded article has the strength required for a golf tee and is biodegradable, it is naturally decomposed by bacteria etc. and returned to the soil when it is discarded outdoors, so that it does not pollute the golf course. In addition, since it is non-toxic and edible, it can be used as a feed for small animals such as insects, birds or squirrels and can eliminate environmental pollution. Furthermore, by adding an extender composed of a dry powder of vegetable fiber to this composition, the weight of the tay can be reduced, the rigidity and the edibility can be further enhanced, and the practicality as a tay can be improved.
