Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a golf tee, and in particular, the material used is made of a natural substance, and the kneaded product based on the substance has plasticity, and is molded into a tee-shaped mold. After being molded and demolded, the product is dried and becomes a product, so even if it is left on a golf course after being used for golf, it will easily weather.

The present invention relates to a golf tee that is returned to the soil, does not cause any damage to the golf course, and also contributes to soil improvement by warping.

[Conventional technology]

A golf tee is an indispensable piece of equipment for modern golf. Therefore, a wide variety of applications related to this have been filed. However, most of them emphasize form. In Japan, as the passion for golf increases, damage to golf courses becomes a problem, and damage to golf tees themselves has also increased. For example, golf course management problems often arise, such as injuries caused by tees thrown on the golf course, or the need to pick up tees individually to prevent damage such as getting entangled in grass mowers during ground maintenance. It's a place to listen. Therefore, recently there has been an increase in the number of applications for golf tees. Therefore, the applications related to the present invention will be described below among the researched applications based on the above-mentioned reasons.

However, regarding these applications, the inventor filed the application earlier in 1988.
Although it was described and explained in Patent Application No. 156698, it will be briefly explained below.

(a) Utility Model Application Publication No. 59-102073 Although the gist of the present application describes compression molding of sawdust, the inventor's experience suggests that molding only sawdust would be difficult.

(b) Utility Model Application Publication No. 60-73503 The gist of the present application states that the ball mounting portion, the tip of the tear tab, and the support portion that connects the two are composed of a solid fertilizer body; The material is obviously different from the invention.

(c) Utility Model Application No. 62-186765 The gist of the present application is that the material is composed of soil or fertilizer raw materials, but there are problems with the possibility of mass molding and the strength of the obtained tee.

(D) 9 Utility Model Publication No. 1989-78955 Although the gist of the present application describes that wood fiber or powder is kneaded with a synthetic resin adhesive as a material and then heated and molded, the present invention uses an inorganic material as a material. They differ in that they are made of organic materials and molded at room temperature.

As is clear from the above application examples, applications have been filed in which plastics, natural inorganic soil, or organic wood powder, etc., are used alone as materials for golf tees, but the golf tee of the present invention is similar to It uses natural materials, but it is made by using natural inorganic and organic materials, plasticized and molded using an aqueous solution of hydrophilic adhesive, and the purpose is to prevent natural weathering even if left unused after use. The point is that it does not cause any damage to the golf course.

[Problem to be solved by the invention]

As mentioned above, the present invention uses natural inorganic and organic materials as materials for golf tees, plasticizes them using water containing a hydrophilic adhesive, and molds them at almost room temperature. , Also, the obtained product has considerable strength as a tee,
Moreover, it easily weathers even if it is abandoned after being used as a tee.
The aim was to provide something that would be returned to the ground and would not cause any damage.

[Means to solve the problem]

For the above purpose, the inventor chose a finely powdered natural material as the material for the golf tee, used something like kaolin as the inorganic material, and discarded rice bran as the organic material, and added a hydrophilic adhesive to this material. The mixture was mixed with dissolved water and made plastic, which was then pressed into a tee-shaped mold at almost room temperature, molded, demolded, and dried to obtain a golf tee.

[Effect]

The golf tee based on the present invention is a universal and inexpensive material, and the manufacturing method is simple.Although the golf tee has appropriate strength, it is easily weathered, and particularly easily disintegrated by rainwater. This is a major feature in that even if they are left unattended on a golf course, they will be returned to the soil, and even if they may contribute to the soil effect, they will not cause any damage.

〔Example〕

The gist of manufacturing the golf tee of the present invention is to first use a pulverized organic material as a main ingredient, mix the same pulverized inorganic material with this, add water in which the required hydrophilic adhesive is dissolved,
A golf tee is obtained by compressing and molding a plastic material obtained by thorough kneading into a tee-shaped mold, and then removing the mold and drying the product.

This will be explained in detail below.

This application was previously filed by the inventor in Japanese Patent Application No. 156698/1983.
What differs from No. 1 is the ratio of the amount of inorganic material to organic material mixed, and that organic material is the main component.

A major cause of this was the problem of plasticization of these mixtures. Initially, when the amount of organic material was increased, it was difficult to compress the plastic material obtained in the manufacturing process into a mold, mold it, and then release it from the mold using air pressure or the like. For example, the molded product was prone to collapse and was difficult to demold. As a result of various studies on the cause of this, it was found that the pulverization of the organic material was poor. However, this bound starch and grain flour are not much of a problem, but the bran that belongs to the seed cortex of organic materials with low market value, which is expected to have low market value.
This is because bran, mineral powder, etc. are difficult to pulverize. Fortunately, however, a certain pulverizer was able to turn it into a fine powder. Therefore, in order to obtain a plastic body similar to that of pulverized starch, a manufacturing process as in the present application using a mixture of organic materials and inorganic materials as a main ingredient was established.

Next, each step of the manufacturing process of the present application will be explained in detail.

The first inorganic materials used are kaolin, acid clay, diatomaceous earth and commercially available clays or mixtures thereof.

Among these, the kaolin one is white and colored to pale yellowish brown according to the above-mentioned order. Therefore, among these, kaolin is desirable as a raw material.

Next, as an organic material, starch flour (coix barley) is used.

These include corn, wheat flour), seed cortex (bran, bran, tohuka), and wood flour.

The organic materials, starch and flour, are easily pulverized, and in particular, a pure white mixture of starch and kaolin can be obtained. The flour is colored pale yellow-brown depending on the color.

Also, since these contain starch, they require time to dry because they are dried at room temperature.

Next, the bran, bran, or wood powder (mineral powder) that forms the seed cortex is difficult to pulverize as described above, and therefore the plastic material obtained from the main seed has problems in molding and demolding. .

Fortunately, it is no exaggeration to say that by pulverizing these, the subjectivity of the present application was resolved. However, the scope of the present application is limited to the mixing ratio of 2% inorganic matter and 98% organic matter; for example, in the case of molding only bran, demolding becomes somewhat difficult.

Therefore, the addition of inorganic materials tends to gradually improve molding and demolding, and is useful for lightening the degree of coloration (trade color) of the product. For example, in the case of an organic material alone, adding more water to increase the plasticity will improve the plasticity, but the product will become softer, making it more difficult to clean the base plate, and it will take longer to dry, causing problems in terms of cost.

Further, the advantage of mixing inorganic materials is that, as mentioned above, this mixture tends to gradually improve the plasticity, reduce the degree of coloring of the product, and tend to increase the strength of the product. However, in this embodiment, the inorganic material is 49% and the organic material is 51% in weight ratio because a higher mixing ratio of both falls within the claims of the previous patent.

Next, natural hydrophilic adhesives include gelatin (glue) modified starch products (dextrin, alpha starch), caseinate, rubber latex, CMC, methyl cellulose, etc., and synthetic resins include polyvinyl acetate emulsion, polyacrylic An acid ester emulsion was used. Among the above, gelatin, modified starch, and caseinate do not significantly change the plasticity of the kneaded product and the product, but it is necessary to use more gelatin and caseinate than the latter adhesive. For example, an 8% aqueous solution of caseinate was used. Furthermore, products manufactured using rubber latex using a similar manufacturing process were weak in strength, but the use of synthetic rubber latex should be considered in the future.

Both CMC and methylol cellulose underwent similar actions during the manufacturing process. For example, in this case a 0.5% aqueous solution was used.

However, methylol cellulose is more expensive than CMC. Polyvinyl acetate emulsions and polymethacrylic ester emulsions are then commercially available at approximately 50% strength. Both of these were used as 0.5% aqueous solutions, but the same actions as above occurred during the manufacturing process, and almost no change was observed in the products.

However, polymethacrylate emulsion is expensive.

In the present invention, as described above, the finely powdered inorganic material and organic material are mixed at an appropriate weight ratio, and the aqueous solution containing the hydrophilic adhesive is added thereto and kneaded to form a plastic body into a T-shaped mold. After being compressed and molded, the mold is demolded using air pressure, etc., and then dried at an appropriate temperature to form a product. In this case, the amount of the hydrophilic adhesive aqueous solution added has a large effect on the plasticization.

In the present invention, the amount of the aqueous solution added is 35% of the total weight of the raw materials.
The ratio was set to 55%. The reason for this is that when the amount of the aqueous solution added to the amount of mixed materials is 30%, a slight plasticization phenomenon is observed, and appropriate plasticity is exhibited at 40 to 45% of the amount added, depending on the mixing ratio of the raw materials.

Furthermore, increasing the addition of the aqueous solution increases the plasticity, but the molded product becomes soft and difficult to handle, and if it exceeds 55%, it takes a long time to dry the product, resulting in high costs.

Although hydrophilic adhesives are inherently sticky, their plasticity in cross-wire or molding seems to be largely controlled by the amount of water added.

However, in this case, the water content of the adhesive considerably influences the strength of the product. For example, the concentration of water of the same adhesive is 0.
It is clearly recognized that the strength (bending) of the product is improved by increasing it to 2% to 5%. However, the strength of the product is determined by the inherent adhesive strength of the raw materials, so the adhesive strength of the adhesive and a certain level of strength (the bending strength of the wood pine shaft) is sufficient, and it is also important to consider this from a cost perspective. There is a need for Therefore, in the experimental example of this example, the concentration is 0.
．． 5% was used.

Next, regarding the disintegration of the golf tee obtained in this example, it was observed by immersing it in water.As soon as the product tee was immersed in water, the surface began to swell and gradually swelled toward the center. Complete disintegration was observed after about 2 hours. This is a major feature of the golf tee based on this embodiment.

Next, an experimental example will be shown.

The kneaded mixture was pressed into a T-shaped mold and molded, and the mold was removed and dried to form a product. The surface of the product was yellowish brown, and the strength was almost the same as that of the matsushi shaft.

E. Mix 4.5 g of the same kaolin as above and 5.5 g of rice bran, and add 0.5 g of polyacrylic acid ester emulsion.
After adding and kneading 4.5 g of water containing 5 g of water, the mixture was pressed into a tee-shaped mold and molded, and then removed from the mold to obtain a dry product.

The surface of the product was pale yellowish brown, and the strength was slightly stronger than that of the Matsushi shaft.

〔Effect of the invention〕

The raw materials for the golf tee according to the present invention are abundant and inexpensive. In particular, among the organic materials used, most of them are discarded, or even if they are used, rice bran, bran, wood flour, etc., which are mostly used as fertilizer, are used. Furthermore, even if this product is abandoned after use on a golf course, it will easily weather and return to the soil without leaving any damage, so it holds great promise as a golf tee in the future.
