Abstract

A high visibility inflated game ball such as a basketball, football, soccer ball or volleyball. The game ball includes a central inflated portion and a synthetic rubber cover formed over the central inflated portion. The cover has fluorescent pigment, fluorescent dye, and/or optical brighteners incorporated therein in order to impart to the cover a reflectance of at least 75% in at least a portion of the visible spectrum. In another embodiment, reflective metallic particles are incorporated in addition to, or in place of the pigment, dye and optical brightener in order to add a glittery appearance to the ball cover. The particularly preferred game ball of the invention is a basketball, and is particularly useful at dusk when conventional basketballs of a dull orange color become difficult to see.

Claims

1. A high visibility game ball, comprising:

a central inflated portion, and

a cover formed over said central inflated portion, said cover including a plurality of panels at least one of which comprises a peroxide cured synthetic rubber and a tinting agent for enhancing the visibility of the ball, a portion of said ball which includes said at least one panel having a reflectance of at least 75% in a part of the visible spectrum.

2. A game ball according to claim 1, wherein said tinting agent includes at least one member selected from the group consisting of fluorescent dyes, fluorescent pigments, and optical brighteners.

3. A game ball according to claim 1, wherein said peroxide cured synthetic rubber comprises a member selected from the group consisting of ethylene propylene diene monomer, ethylene propylene rubber, and a blend of ethylene propylene diene monomer with at least one of polyisoprene rubber and polybutadiene rubber.

4. A game ball according to claim 1, wherein said tinting agent includes about 0.05-2.0 parts by weight of an optical brightener based upon 100 parts by weight of synthetic rubber.

5. A game ball according to claim 1, wherein said tinting agent includes about 0.5-5.0 parts by weight of a fluorescent pigment based upon 100 parts by weight of synthetic rubber.

6. A game ball according to claim 1, wherein said tinting agent includes about 0.05-2.0 parts by weight of a fluorescent dye based upon 100 parts by weight of synthetic rubber.

7. A game ball according to claim 6, wherein said ball further includes a clear, synthetic finish coating over said cover.

8. A game ball according to claim 1, wherein said central inflated portion has an outer surface with a reflectance of at least about 40% in a part of the visible spectrum.

9. A game ball according to claim 1, wherein said cover has a thickness, and said at least one panel further includes highly reflective particles with a maximum particle size which is smaller than said thickness of said cover.

10. A game ball according to claim 1, wherein said ball is a basketball.

11. A game ball according to claim 1, wherein said cover is translucent.

12. A game ball according to claim 1, wherein said portion of said ball which includes said at least one panel has a reflectance of at least 100% in a part of the visible spectrum.

13. A high visibility game ball comprising:

a central inflated portion, and

a translucent cover formed over said central inflated portion, said covering including a plurality of panels, at least one of which comprises a synthetic rubber and a material for enhancing the visibility of the ball, said material including a member selected from the group consisting of reflective particles having faces with a reflectance of at least 75%, and a tinting agent which imparts to at least a portion of the cover panel a reflectance of at least 75% in a part of the visible spectrum.

14. A game ball according to claim 13, wherein said material for enhancing the visibility of the ball includes reflective particles which comprise at least one member selected from the group consisting of metal flake, iridescent glitter, metallized film, and colored polyester foil.

15. A game ball according to claim 13, wherein said at least one panel contains about 0.2-1.5 parts by weight of reflective particles based upon 100 parts by weight of synthetic rubber.

16. A game ball according to claim 13, wherein said material for enhancing the visibility of the ball includes reflective particles having faces with a reflectance of at least 95%.

17. A method of forming a high visibility game ball, comprising the steps of:

forming a central inflated portion, and

forming a cover over said central inflated portion, said cover including a plurality of panels at least one of which comprises a peroxide cured synthetic rubber and a tinting agent for enhancing the visibility of the ball, said tinting agent being present in an amount sufficient to provide a portion of said ball which includes said at least one panel with a reflectance of at least 75% in a portion of the visible spectrum.

18. A method according to claim 17, wherein said peroxide cured synthetic rubber comprises a member selected from the group consisting of ethylene propylene diene monomer, ethylene propylene rubber, and a blend of ethylene propylene diene monomer with at least one of polyisoprene rubber and polybutadiene rubber.

19. A method according to claim 17, wherein said tinting agent includes at least one member selected from the group consisting of fluorescent dyes, fluorescent pigments, and optical brighteners.

20. A method according to claim 17, wherein said tinting agent is present in a quantity sufficient to provide that said cover is translucent.

21. A method according to claim 17, where the step of forming said cover includes providing said portion of said ball which includes said at least one panel with a reflectance of at least 100% in a portion of the visible spectrum.

22. A method according to claim 17, further comprising the step of forming a clear synthetic finish coating over said cover.

23. A method of forming a high visibility game ball, comprising:

forming a central inflated portion, and

forming a translucent synthetic rubber cover over said central inflated portion, said cover including a plurality of panels, at least one of which comprises a synthetic rubber and a material for enhancing the visibility of the ball, said material including a member selected from the group consisting of reflective particles having faces with a reflectance of at least 75% and a tinting agent which imparts to at least a portion of the cover panel a reflectance of at least 75% in a part of the visible spectrum.
