Abstract

An aerosol dispenser. The aerosol dispenser is made from materials which can go into a single recycling stream having a single class of materials, as defined by the Society of the Plastics Industry, and particularly may exclusively comprise Class 1 materials with no flammable product/propellant present.

First claim

What is claimed is:

1. A recyclable aerosol dispenser comprising:
an outer container having a closed end bottom at a first end and an open neck at a second end and defining an outer container volume therein;
a valve assembly for selectively dispensing product from the aerosol dispenser,
wherein the foregoing components comprise materials that are accepted into a single recycling stream,
wherein the outer container having a diameter less than or equal to about 7.62 cm, and
wherein the outer container having a volume ranging from about 118 cc to about 1000 cc; and
a nonflammable propellant, the nonflammable propellant having a gage pressure of less than about 1100 kPa @ 50 C.

2. The recyclable aerosol dispenser of claim 1 , wherein each of the valve assembly and the outer container comprises Class 1 materials.

3. The recyclable aerosol dispenser of claim 2 , wherein the gage pressure is less than about 965 kPA @ 50 C.

4. The recyclable aerosol dispenser of claim 3 , wherein the gage pressure is less than about 620 kPa @ SOC.

5. The recyclable aerosol dispenser of claim 3 , wherein the outer container has a volume ranging from about 280 to about 592 cc.

6. The recyclable aerosol dispenser of claim 1 , wherein each of the valve assembly and the outer container is made from a material consisting of a single class of recyclable materials as defined by the Society of the Plastics Industry.

7. A recyclable aerosol dispenser comprising:
an outer container having a closed end bottom at a first end and an open neck at a second end and defining an outer container volume therein;
an inner bag defining an inner bag volume therein and having a product therein;
a valve assembly joining the inner bag to the neck, wherein the valve assembly is configured to selectively dispense product from the inner bag,
wherein the foregoing components comprise materials that are accepted into a single recycling stream, and
wherein the outer container having a volume between about 118 cc and about 1000 cc, the inner bag having an inner bag volume less than or equal to about 97% of the outer container volume prior to first use; and
a nonflammable propellant intermediate the outer container and the inner bag, the nonflammable propellant having a gage pressure of less than about 1100 kPa @ 50 C.

8. The aerosol dispenser of claim 7 , wherein the outer container consists essentially of PET.

9. The aerosol dispenser of claim 8 , comprising a seal preventing leakage through the neck to ambient, wherein the seal comprises TPE.

10. The aerosol dispenser of claim 9 , wherein the seal consists essentially of a hydrophilic TPE-E based compound.

11. The aerosol dispenser of claim 7 , wherein the inner bag has an inner bag volume between about 60 to about 95% of the outer container volume prior to first use.

12. The aerosol dispenser of claim 11 , wherein the inner bag has an inner bag volume between about 70 to about 90% of the outer container volume prior to first use.

13. The aerosol dispenser of claim 7 , wherein each of the inner bag, valve assembly, and the outer container is made from a material consisting of a single class of recyclable materials as defined by the Society of the Plastics Industry.

14. A recyclable aerosol dispenser comprising:
an outer container having a closed end bottom at a first end and an open neck at a second end and defining an outer container volume therein;
a valve assembly for selectively dispensing product from the aerosol dispenser;
a seal preventing leakage through said neck to ambient,
wherein the outer container having a diameter less than or equal to about 7.62 cm,
wherein the outer container having a volume ranging from about 118 cc to about 1000 cc; and
a nonflammable propellant, the nonflammable propellant having a gage pressure of less than about 1100 kPa @ 50 C,
wherein the foregoing components comprise materials that are accepted into a single recycling stream, and each of the foregoing components consists essentially of virgin material or regrind thereof.

15. The recyclable aerosol dispenser of claim 14 , comprising product therein, the product comprising not more than about 15.8 weight percent of ethanol and/or or isopropyl alcohol in an aqueous mix.

16. The recyclable aerosol dispenser of claim 15 , wherein the product and the propellant are intermixed within the outer container.

17. The recyclable aerosol dispenser of claim 16 , comprising a dip tube communicating from the outer container to the valve assembly for dispensing of the intermixed product and propellant.

18. The recyclable aerosol dispenser of claim 14 , comprising indicium on the outside of the outer container indicating the aerosol dispenser complies with DOT SP 14223.

19. The recyclable aerosol dispenser of claim 14 , wherein the propellant comprises a Trans-1,3,3,3-tetrafluoroprop-1-ene.

20. The recyclable aerosol dispenser of claim 19 , having a volume ranging from about 280 to about 592 cc.

21. The recyclable aerosol container of claim 19 , comprising an inner bag containing the product therein so that the product is in communication with the valve assembly, and separating the product from the propellant, the inner bag having a volume ranging from about 60% to about 90% of the volume of the outer container volume.

22. The recyclable aerosol container of claim 21 , wherein the propellant has a pressure ranging from about 210 to about 965 kPa @ 50 C.

23. The recyclable aerosol container of claim 14 , wherein each of the seal, valve assembly, and the outer container is made from a material consisting of a single class of recyclable materials as defined by the Society of the Plastics Industry.
