  • Patent number: 8403330
    Abstract: A ball net of box type comprises a front loop, a rear loop, and first and second side loops. The enclosing net portion are for covering a top hole formed by top portions of the loops, two side holes formed by the side loops, and a rear hole formed by the rear loop, so as to enclose the box-type space from four sides. The vertical side straight portions of neighboring loops are hold together by fabric holder portions. The top curved portion of the front loop protrudes above the top straight portions of the other loops, such that a front opening defined by the front loop provides a receiving area larger than the other holes defined by the other loops especially in a upper portion of the receiving area. The front loop has a larger area than the other loops in a lower portion of the receiving area.
