Abstract

The present invention relates to a ball shaped product and a method for making the same. The method includes the following steps of: (a) placing a ball shaped interior material on a supporting seat, wherein a part of an outer surface of the ball shaped interior material is exposed outside the supporting seat; (b) placing the ball shaped interior material and the supporting seat in a chamber; (c) covering a wrapping material on the chamber; (d) vacuum pumping the chamber, so that the wrapping material is attached to the exposed part of the outer surface of the ball shaped interior material; (e) releasing the vacuum of the chamber; and (f) rotating the ball shaped interior material, and repeating the step (a) to step (e) at least one time.

Claims

1. A method for making a ball shaped product, comprising:

(a) placing a ball shaped interior material on a supporting seat, wherein a part of an outer surface of the ball shaped interior material is exposed outside the supporting seat;

(b) placing the ball shaped interior material and the supporting seat in an accommodating space of a chamber, wherein the chamber has an opening;

(c) covering a wrapping material on the opening of the chamber;

(d) vacuum pumping the chamber, so that the wrapping material is attached to the exposed part of the outer surface of the ball shaped interior material;

(e) releasing the vacuum of the chamber; and

(f) rotating the ball shaped interior material, and repeating the step (a) to step (e) at least one time.

2. The method according to claim 1, wherein in the step (c), the material of the wrapping material is thermoplastic urethane (TPU), polyurethane (PU), rubber, polyvinyl chloride (PVC), nylon, polyethylene terephthalate (PET) or polycarbonate (PC).

3. The method according to claim 1, wherein in the step (c), the wrapping material has an adhesive layer.

4. The method according to claim 1, wherein after the step (e) or step (f), the method further comprises a step of cutting away the wrapping material that is not attached to the ball shaped interior material.

5. A method for making a ball shaped product, comprising:

(a) placing a ball shaped interior material on a first supporting seat, wherein a first outer surface of the ball shaped interior material is exposed outside the first supporting seat;

(b) placing the ball shaped interior material and the first supporting seat in an accommodating space of a first chamber, wherein the first chamber has an opening;

(c) covering a first wrapping material on the opening of the first chamber;

(d) vacuum pumping the first chamber, so that the first wrapping material is attached to the first outer surface of the ball shaped interior material;

(e) releasing the vacuum of the first chamber;

(f) rotating the ball shaped interior material, and then placing the ball shaped interior material on a second supporting seat, wherein a second outer surface of the ball shaped interior material is exposed outside the second supporting seat;

(g) placing the ball shaped interior material and the second supporting seat in an accommodating space of a second chamber, wherein the second chamber has an opening;

(h) covering a second wrapping material on the opening of the second chamber; and

(i) vacuum pumping the second chamber, so that the second wrapping material is attached to the second outer surface of the ball shaped interior material.

6. The method according to claim 5, wherein after the step (a), the method further comprises a step of forming an adhesive layer on the first outer surface;

and after the step (f), the method further comprises a step of forming an adhesive layer on the second outer surface.

7. The method according to claim 5, wherein in the step (c), the first wrapping material has an adhesive layer;

and in the step (h), the second wrapping material has an adhesive layer.

8. A ball shaped product, comprising:

a ball shaped interior material; and

less than four wrapping materials, adhered to the ball shaped interior material.

9. The ball shaped product according to claim 8, wherein the ball shaped interior material is a bladder and has a perfect spherical shape, an elliptical spherical shape or an egg shape;

and the ball shaped product further comprises an adhesive layer, located between the ball shaped interior material and the wrapping materials.

10. The ball shaped product according to claim 8, wherein the material of the wrapping material is thermoplastic urethane (TPU), polyurethane (PU), rubber, polyvinyl chloride (PVC), nylon, polyethylene terephthalate (PET) or polycarbonate (PC);

the wrapping materials are adhered to the ball shaped interior material by vacuum suction; and

the number of the wrapping materials is two.
