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 the following components:
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 cup joining a collapsible inner bag to said neck, said bag being adapted to contain a product therein,
a valve assembly disposed in said valve cup for selectively dispensing said product from said aerosol dispenser,
a seal preventing leakage between said valve cup and said neck to ambient,
wherein all of the foregoing components are selected from the group consisting of a single class of recyclable materials as defined by the Society of the Plastics Industry,
said outer container having a diameter less than or equal to about 7.62 cm,
said outer container having a volume ranging from about 118 cc to about 1000 cc, and
a nonflammable propellant, said nonflammable propellant having a gage pressure of less than about 1100 kPa @ 50C.

2. A recyclable aerosol dispenser according to claim 1 wherein each said component selected from a single class of recyclable materials is selected from Class 1 recyclable materials.

3. A recyclable aerosol dispenser according to claim 2 wherein said gage pressure is less than about 965 kPA @ 50C.

4. A recyclable aerosol dispenser according to claim 3 wherein said gage pressure is less than about 620 kPa @ 50C.

5. A recyclable aerosol dispenser according to claim 3 wherein said outer container has a volume ranging from about 280 to about 592 cc.

6. A recyclable aerosol dispenser comprising the following components:
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 cup sealed to said neck,
an inner bag defining an inner bag volume therein and having a sprayable product therein, said inner bag being joined to said valve cup,
a valve assembly disposed in said valve cup for selectively dispensing said sprayable product from said inner bag,
wherein all of the foregoing components are selected from the group consisting essentially of class 1 recyclable materials as defined by the Society of the Plastics Industry,
said outer container having a volume between about 118 cc and about 1000 cc, said inner bag having an inner bag volume less than or equal to about 97% of said outer container volume prior to first use, and
a nonflammable propellant intermediate said outer container and said inner bag, said nonflammable propellant having a gage pressure of less than about 1100 kPa @50C.

7. An aerosol dispenser according to claim 6 wherein said outer container consists essentially of PET.

8. An aerosol dispenser according to claim 1 wherein said seal comprises TPE.

9. An aerosol dispenser according to claim 8 wherein said seal consists essentially of a hydrophilic TPE-E based compound.

10. An aerosol dispenser according to claim 6 wherein said inner bag has an inner bag volume between about 60 to about 95% of said outer container volume prior to first use.

11. An aerosol dispenser according to claim 10 wherein said inner bag has an inner bag volume between about 70 to about 90% of said outer container volume prior to first use.

12. A recyclable aerosol dispenser comprising the following components:
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 cup joining an inner bag to said neck,
a valve assembly disposed in said valve cup for selectively dispensing a product from said aerosol dispenser,
a seal preventing leakage through said neck to ambient,
said outer container having a diameter less than or equal to about 7.62 cm,
said outer container having a volume ranging from about 118 cc to about 1000 cc, and
a nonflammable propellant, said nonflammable propellant having a gage pressure of less than about 1100 kPa @ 50C,
wherein all of the foregoing components are selected from the group consisting essentially of a single class of recyclable materials as defined by the Society of the Plastics Industry, and each of the foregoing components consists essentially of virgin material or regrind thereof.

13. A recyclable aerosol dispenser according to claim 12 further comprising said product therein, said product comprising not more than about 15.8 weight percent of ethanol and/or or isopropyl alcohol in an aqueous mix.

14. A recyclable aerosol dispenser according to claim 13 wherein said product and said propellant are intermixed within said outer container.

15. A recyclable aerosol dispenser according to claim 14 further comprising a dip tube communicating from said outer container to said valve assembly for dispensing of said intermixed product and propellant.

16. A recyclable aerosol dispenser according to claim 12 further comprising indicium on the outside of said outer container indicating said aerosol dispenser complies with DOT SP 14223.

17. A recyclable aerosol dispenser according to claim 12 wherein said propellant comprises a Trans-1,3,3,3-tetrafluoroprop-1-ene.

18. A recyclable aerosol dispenser according to claim 17 having a volume ranging from about 280 to about 592 cc.

19. A recyclable aerosol container according to claim 17 further comprising said product in said inner bag, so that said product is in communication with said valve assembly, and said product is separated from said propellant, said inner bag having a volume ranging from about 60% to about 90% of said volume of said outer container volume.

20. A recyclable aerosol container according to claim 19 wherein said propellant has a pressure ranging from about 210 to about 965 kPa @ 50C.
