Patent ID: 8403330

Claim:
A ball net of box type comprising: a front loop comprising a top curved portion, two side straight portions, a bottom straight portion, and two lower corner portions; a rear loop comprising four straight portions and four corner portions, wherein the rear loop is disposed such that a plane defined by the rear loop is parallel to a plane defined by the front loop; a first side loop comprising four straight portions and four corner portions, wherein a side one of the four straight portions engages foldably one of the two side straight portions of the front loop, and wherein another side one of the four straight portions engages foldably one of the four straight portions of the rear loop; a second side loop comprising four straight portions and four corner portions, wherein a side one of the four straight portions engages foldably one of the two side straight portions of the front loop, and wherein another side one of the four straight portions engages foldably one of the four straight portions of the rear loop, such that the front loop, the rear loop, the first side loop, and the second side loop form a box-type space in the middle; a plurality of triangular holders for holding two straight portions having a corner portion inbetween so as to form a substantially right angle between the two straight portions; and an enclosing net portion 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 box-type space from four sides, wherein vertical side straight portions of neighboring loops are hold together by fabric holder portions, wherein 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, and wherein the front loop has a larger area than the other loops in a lower portion of the receiving area.
