Abstract

A plastic package for dispensing a product in aerosol form having improved crazing resistance and sustainability is disclosed. The plastic package comprises a bottle having a delivery device, a valve to control flow, and a stable plastic package that holds the product when sealed using the valve. In one embodiment, at least a portion of the plastic package comprises PEF.

First claim

What is claimed is:

1. A plastic package for dispensing a product in aerosol form comprising a bottle having a delivery device, a valve to control flow, and a stable plastic package that holds the product when sealed using said valve, wherein at least a portion of said stable plastic package comprises poly(ethylene 2,5-furandicarboxylate) (PEF).

2. The plastic package of claim 1 , further comprising a bag connected to said valve, wherein said bag contains the product, and further, wherein the product is a liquid, gel, suspension, solution, paste, or foam.

3. The plastic package of claim 2 , wherein said bag comprises PEF.

4. The plastic package of claim 1 , wherein said bottle has a neck region and said neck region comprises PEF.

5. The plastic package of claim 1 , wherein said plastic package further comprises a base cup and said base cup comprises PEF.

6. The plastic package of claim 1 , wherein said plastic package further comprises a label and said label comprises PEF.

7. The plastic package of claim 1 , wherein said plastic package further comprises a cap and said cap comprises PEF.

8. The plastic package of claim 1 , wherein said plastic package further comprises a trigger and said trigger comprises PEF.

9. The plastic package of claim 1 , wherein said product contains a propellant, wherein said propellant is selected from the group consisting of 1,1-difluoroethane, 1,1,1,2-tetrafluoroethane, butane, isobutane, propane, isopentane, pentane, nitrous oxide, or combinations thereof.

10. The plastic package of claim 2 , wherein the plastic package is pressurized using an inert gas.

11. The plastic package of claim 10 wherein the inert gas is selected from the group consisting of nitrogen, carbon dioxide, argon, air, and combinations thereof.

12. The plastic package of claim 1 , wherein said package is substantially clear.

13. The plastic package of claim 12 , wherein said plastic package further comprises strengthening materials selected from the group consisting of glass fibers, glass spheres, and mixtures thereof.

14. The plastic package of claim 1 wherein from about 10% to 100% of the plastic package comprises bio-based content.

15. The plastic package of claim 1 , wherein the PEF is blended with farnesene.

16. The plastic package of claim 1 wherein said package is made from a blend of PEF and one or more other materials selected from the group consisting of Poly(ethylene terephthalate) (PET), polyester, polyamide, polycarbonate, polyoxymethylene, polyacrylonitrile, polyolefin, fluoropolymers, virgin, recycled and regrind versions of all these polymers, and combinations thereof.

17. The plastic package of claim 1 wherein said bottle is formed from multiple layers of polymer material.

18. The plastic package of claim 17 wherein said at least one of said multiple layers is a barrier material.

19. The plastic package of claim 1 wherein said bottle comprises one or more colored pigments or dyes.

20. A plastic package for dispensing a product in aerosol form comprising a bottle having a delivery device, a valve to control flow, a stable plastic package, and a bag inside said stable plastic package, wherein the bag holds the product to be dispensed, and further wherein said bag comprises PEF.

21. The plastic package of claim 1 wherein at least a portion of said bottle is resistant to crazing.

22. The plastic package of claim 4 wherein at least said neck region of said bottle is resistant to crazing.
