Bottle containing recycled polymers
View Patent ↗The invention provides a bottle having at least three layers in which the outer and inner layers contain a metallocene polyethylene polymer and the middle layer comprises virgin high density polyethylene, regrind and post-consumer recycled resin, with the bottle having at least 10 % light transmittance in the visible spectrum.
1. A bottle fabricated from at least three layers, comprising a middle layer, an outer layer and an inner layer wherein the outer and inner layers are a metallocene polyethylene polymer, and the middle layer comprises virgin high density polyethylene, regrind and post-consumer recycled resin, said bottle having at least 10% transmittance of light in the visible spectrum.
2. A bottle according to claim 1 , having at least 15% transmittance of light in the visible spectrum.
3. A bottle according to claim 1 , having at least 20% transmittance of light in the visible spectrum.
4. A bottle according to claim 1 , having at least 25% transmittance of light in the visible spectrum.
5. A bottle according to claim 1 , wherein said middle layer is comprised of at least 25% recycled resin.
6. A bottle according to claim 1 , wherein said outer and/or inner layer is comprised of a blend of metallocene polyethylene and high density polyethylene.
7. A bottle according to claim 1 , wherein said outer and inner layer each comprise 5-15% of the total thickness of the bottle wall.
8. A bottle comprising a downwardly extending body fabricated from at least three layers, comprising an external and internal layer wherein the external and internal layer are a metallocene polyethylene polymer, a middle layer between the external and internal layers and comprising recycled resin, virgin high density polyethylene and regrind, and wherein said bottle further comprises a finish having an annular mouth, said body extending axially downwardly along a vertical axis from said finish to a base; said body including a shoulder extending outwardly and downwardly below said finish, said bottle having at least 10% transmittance of light in the visible spectrum.
9. A bottle according to claim 8 , having at least 15% transmittance of light in the visible spectrum.
10. A bottle according to claim 8 , having at least 20% transmittance of light in the visible spectrum.
11. A bottle according to claim 8 , having at least 25% transmittance of light in the visible spectrum.
12. A bottle according to claim 1 wherein the middle layer has a thickness of about 80% of all layers of a wall of the bottle.
13. A bottle according to claim 1 wherein the middle layer comprises about 25% post-consumer recycled resin, about 25% virgin high density polyethylene and about 50% regrind.
14. A bottle according to claim 1 wherein a wall of the bottle fabricated from the at least three layers has a thickness of about 1 mm.
15. A bottle according to claim 8 wherein the middle layer has a thickness of about 80% of all layers of a wall of the bottle.
16. A bottle according to claim 8 the middle layer comprises about 25% post-consumer recycled resin, about 25% virgin high density polyethylene and about 50% regrind.
17. A bottle according to claim 8 wherein a wall of the bottle fabricated from the at least three layers has a thickness of about 1 mm.
