## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 2)

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

### Claim 4 (depends on 3)

The recyclable aerosol dispenser of claim 3, wherein the gage pressure is less than about 620 kPa @ 50 C.

### Claim 5 (depends on 3)

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

### Claim 6 (depends on 1)

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.

### Claim 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.

### Claim 8 (depends on 7)

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

### Claim 9 (depends on 8)

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 7)

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.

### Claim 12 (depends on 11)

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.

### Claim 13 (depends on 7)

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.

### Claim 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;
