## Abstract

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

## Claims

### Claim 1

An aerosol container having a longitudinal axis and comprising:
a polymeric outer container comprising a closed end bottom and an open neck longitudinally opposed thereto;
a valve sealed to the outer container in fluid tight relationship by an outer container seal;
a dip tube sealed to the valve in fluid tight relationship by a product delivery device seal,
wherein at least one of the product delivery device seal and the outer container seal is a spin weld,
and wherein the product delivery device seal is radially spaced apart from the outer container seal;
a propellant disposed within the outer container; and
a product disposed within the outer container.

### Claim 2 (depends on 1)

The aerosol container of claim 1, wherein the product delivery device seal is spaced radially inward of the outer container seal.

### Claim 3 (depends on 1)

The aerosol container of claim 1, wherein the product delivery device seal is spaced below and radially inward of the outer container seal.

### Claim 4 (depends on 1)

The aerosol container of claim 1, comprising an actuator operably connected to the valve for selectively dispensing the product from the aerosol dispenser.

### Claim 5

An aerosol container having a longitudinal axis and comprising:
a polymeric outer container comprising a closed end bottom and an open neck longitudinally opposed thereto;
a valve spin welded to the outer container in fluid tight relationship by an outer container weld;
a dip tube spin welded to the valve in fluid tight relationship by a product delivery device weld,
wherein the product delivery device weld being radially spaced apart from the outer container weld, and wherein the outer container weld is disposed radially outward of and contiguous with the product delivery device weld; and
a propellant disposed within the outer container.

### Claim 6 (depends on 5)

The aerosol container of claim 5, wherein the outer container weld has a respective outer container weld thickness in the radial direction and the product delivery device weld has a respective product delivery device weld thickness in the radial direction, the product delivery device weld thickness being substantially the same radial thickness dimension as the outer container weld thickness.

### Claim 7 (depends on 5)

The aerosol container of claim 5, wherein the outer container weld and the product delivery device weld are mutually concentric.

### Claim 8 (depends on 5)

The aerosol container of claim 5, wherein the outer container weld and the product delivery device weld are mutually concentric, and longitudinally spaced apart in different planes.

### Claim 9 (depends on 5)

The aerosol container of claim 5, comprising product dispensable through the dip tube, and an actuator operably connected to the valve for selectively dispensing the product from an aerosol dispenser.

### Claim 10 (depends on 5)

The aerosol container of claim 5, wherein the valve comprises a valve cup.

### Claim 11

An aerosol container having a longitudinal axis and comprising:
a polymeric outer container comprising a closed end bottom and an open neck longitudinally opposed thereto;
a valve welded to the outer container in fluid tight relationship by an outer container weld, and
a dip tube welded to the valve in fluid tight relationship by a product delivery device weld,
the product delivery device weld being radially spaced from the outer container weld, and
wherein the neck of the outer container has an inner periphery, the inner periphery comprising a first annular sealing surface and a second annular sealing surface, the valve being joined to the outer container at the first annular sealing surface and the dip tube being disposed on the second annular sealing surface.

### Claim 12 (depends on 11)

The aerosol container of claim 11, wherein the valve is spin welded to the first annular sealing surface and the dip tube is welded to the second annular sealing surface.

### Claim 13 (depends on 11)

The aerosol container of claim 11, wherein the first annular sealing surface and the second annular sealing surface are perpendicular to the longitudinal axis.

### Claim 14 (depends on 11)

The aerosol container of claim 11, comprising a product disposed in the outer container and an actuator operably connected to said valve for selectively dispensing said product from an aerosol dispenser upon demand to be a functional aerosol dispenser, said aerosol dispenser consisting essentially of polymeric materials.

### Claim 15 (depends on 11)

The aerosol container of claim 11, wherein the inner periphery is stepped such that the first annular sealing surface is longitudinally spaced apart from the second annular sealing surface.

### Claim 16 (depends on 11)

The aerosol container of claim 11, wherein the outer container weld and the product delivery device weld are mutually concentric, and longitudinally spaced apart in different planes.
