The present invention relates to a golf ball that is to fly in a short distance at the time of hitting, in particular the inner body and the outer body constituting the golf ball by injection molding in a double injection method the inner body of the inside of the outer body But, by forming a plurality of wind resistance holes on the surface of the outer body so as not to fly away by the resistance of the wind at the time of hitting so that you can enjoy a variety of golf exercise in a short course to obtain an economic effect It relates to a short-range emergency golf ball that can promote the popularization of the golf movement.

In general, the golf ball is formed of an outer shell of heterogeneous material having good repulsion or elasticity around the nucleus formed therein. The distance and spin of the ball at the time of hitting the ball depends on how many outer shells are included including the nucleus. The amount is determined, and this type is divided into one-piece balls or two-piece balls.

In addition, it is known that a golf ball flies farther when a predetermined scratch is formed on the surface of the ball, that is, the outer surface of the outer shell, and forms a plurality of dimples on the outer surface of the outer shell. The research and development of Korea is concentrated.

The research and development of materials and dimples related to the nucleus and shell of golf balls are conventional technologies of the form derived under the same purpose, such as increasing the distance of golf balls at the time of hitting or inducing detailed golf techniques. However, there is a problem that the result is a demand for a wider field, resulting in enormous facility and maintenance costs for the golf environment.

This economic burden eventually increases the actual cost of playing golf, not only weakening the public base of golf, but also being neglected and avoided by the public because it is perceived as a leisure sport that promotes a sense of incongruity in a social structure where polarization is apparent. There is no limit.

Moreover, the golf course occupies approximately 180 acres (728424m2; 220356 pyeong) of land, making it difficult to secure the necessary land for golf courses in metropolitan areas or resort areas where golf courses are often established. The cost of land, such as land costs, is incurred.

Therefore, it is urgently required to design a golf course that requires a small acre area and can play all the games of a normal golf course.

On the other hand, in consideration of this problem, the short distance golf ball made of a monolithic patent application 1985-0003147 has been conceived to reduce the flying distance of the hit golf ball to obtain the effect of the golf movement in a small area, which is foam molded A golf ball consisting of a thermoplastic polymer and a filler and having a density gradient that increases in radius from the center to the surface of the golf ball, characterized in that the surface has a shape with a hump.

However, in the case of a conventional short-distance golf ball, the emergency distance that is blown at the time of hitting, that is, the flying distance is slightly shorter than that of a conventionally used golf ball, is so far away that the effect of enjoying golf in a small area is not large. Therefore, it does not solve the problems caused by having to have a wide golf course in the prior art.

Therefore, in reality, the economic burden is largely enjoyed by the general public, which does not contribute to the popularization of golf.
