Benefits of technology

[0012]The primary objective of the present invention is to provide a game ball including an easily manufacturing structure for allowing the game ball to be easily and quickly manufactured, without polluting our environment.

Problems solved by technology

However, the PVC materials may not be recycled, and may generate dioxin that may pollute our environment.
However, the catalyzing agent or vulcanizing agent may also pollute our environment.
However, a complicated yarn winding machine or facility is required for winding the yarn about or over or around the inner bladder, and it takes a long time to wind the yarn about or over or around the inner bladder.
However, similarly, the vulcanizing processes and / or materials may also pollute our environment.
However, the manufacturing processes are complicated and time consuming and expensive.

Embodiment Construction

[0019]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.

[0020]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....

Abstract

A game ball includes two molded semi-spherical members each having an outer peripheral portions, and the peripheral portions of the molded semi-spherical members may be engaged with each other and welded or secured together to form the game ball. One of the molded semi-spherical members may include a valve for selectively inflating the game ball. Either of the molded semi-spherical members includes a pattern formed on the outer peripheral portion. The peripheral portions of the molded semi-spherical members may be welded together with such as ultrasonic waves.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a game ball, and more particularly to a game ball including an easily manufacturing structure for allowing the game ball to be easily and quickly manufactured, without polluting our environment.[0003]2. Description of the Prior Art[0004]Various kinds of typical game balls or sports balls have been developed and used, and comprise such as volley balls, foot balls, basket balls, or other inflatable or resilient or bouncing balls that may be made or manufactured with various kinds of manufacturing methods.[0005]Some of the typical game balls or sports balls are made of poly vinyl chloride (PVC) materials which is a chemical material having a strong acid characteristic, and a stabilized agent is required to be added into the PVC materials while making the balls. However, the PVC materials may not be recycled, and may generate dioxin that may pollute our environment.[0006]The other typical ga...
