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 an 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 joined to said neck,
a valve assembly for selectively dispensing product from said aerosol dispenser,
a seal preventing leakage through said neck to ambient,
wherein each of the foregoing components is 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 wherein said product and said propellant are intermixed within said outer container, and
a dip tube communicating from said outer container to said valve assembly for dispensing of said intermixed product and propellant.

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 psig@ 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. An aerosol dispenser according to claim 1 wherein said outer container consists essentially of PET.

7. An aerosol dispenser according to claim 6 wherein said seal comprises TPE.

8. An aerosol dispenser according to claim 7 wherein said seal consists essentially of a hydrophilic TPE-E based compound.

9. A recyclable aerosol dispenser comprising the following components:
an outer container having an 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 joined to said neck,
a valve assembly for selectively dispensing product disposed in said aerosol dispenser 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,
a nonflammable propellant, said nonflammable propellant having a gage pressure of less than about 1100 kPa @ 50C, wherein said product and said propellant are intermixed within said outer container, and
a dip tube communicating from said outer container to said valve assembly for dispensing of said intermixed product and propellant
wherein each of the foregoing components is 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.

10. A recyclable aerosol dispenser according to claim 9 comprising product therein, said product comprising not more than about 15.8 weight percent of ethanol and/or or isopropyl alcohol in an aqueous mix.

11. A recyclable aerosol dispenser according to claim 9 further comprising indicium on the outside of said outer container indicating said aerosol dispenser complies with DOT SP 14223.

12. A recyclable aerosol dispenser according to claim 9 wherein said propellant comprises a Trans-1,3,3,3-tetrafluoroprop-1-ene.

13. A recyclable aerosol dispenser according to claim 12 having a volume ranging from about 280 to about 592 cc.

14. A recyclable aerosol container according to claim 11 wherein said propellant has a pressure ranging from about 210 to about 965 kPa @ 50C.
