Referring to the drawings, a game ball 10 in accordance with the present invention comprises two semi-spherical members or half members 11, 12 made of soft or resilient rubbers or other synthetic materials that may be recycled, and that may be heat sealed, or that may be hot pressed. The two semi-spherical members or half members 11, 12 each may include an outer peripheral portion 13, and the peripheral portions 13 of the two semi-spherical members or half members 11, 12 may then be engaged with each other and heat sealed or welded together by such as ultrasonic waves, or the like, for allowing the two semi-spherical members or half members 11, 12 to be easily and quickly secured together to form the game ball 10.
It is to be noted that the two semi-spherical members or half members 11, 12 may also be formed or made or manufactured with such as molding, or mold-injection processes without vulcanizing processes, such that no chemical materials will pollute our environment. A valve 14 may be attached or secured into one of the two semi-spherical members or half members 11 such as while molding or mold-injecting the two semi-spherical members or half members 11, 12, for allowing the game ball 10 to be selectively inflated by the users or by other inflating pumps or the like.
It is further to be noted that the two semi-spherical members or half members 11, 12 may be easily and quickly molded or mold-injected with one mold device (not shown) for forming one of the game balls 10, such as volley balls, and another mold device (not shown) for forming the other game balls 10, such as foot balls, and a further mold device (not shown) for forming the further game balls 10, such as basket balls, and the other mold devices (not shown) for forming the further game balls 10, such as other inflatable or resilient or bouncing balls, such that only one mold device is good enough for forming or making or manufacturing each of the game balls 10, such as volley balls, foot balls, basket balls, or other inflatable or resilient or bouncing balls.
As shown in
In addition, the two semi-spherical members or half members 11, 12 may be made into a uniform thickness with the molding, or mold-injection processes, and only one hot pressing, or heat sealing or welding process is good enough to secure the two semi-spherical members or half members 11, 12 together to form the game ball 10, without generating any poisonous gases. Furthermore, the soft or resilient rubbers or other synthetic materials for making the two semi-spherical members or half members 11, 12 may be recycled and thus will not pollute our environment, and the recycled materials may further be heated or melted and used to mold or to mold-inject the game balls 10.
Accordingly, the game ball in accordance with the present invention includes an easily manufacturing structure for allowing the game ball to be easily and quickly manufactured, without polluting our environment.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
