Aerosol container

1. A composite spout and bag combination, wherein the composite spout has a polymer coated metal tubular section, adapted to accommodate a valve arrangement, and a plastic fishtail section, adapted to form a leak-proof seal with the bag,

the bag being made from a multilayer film, having a metal foil layer, to provide a barrier, interspersed between plastic layers, to protect the foil and to form a secure bond with the fishtail section, and the fishtail section is partially disposed within the tubular section.

2. A composite spout and bag combination according to claim 1 , wherein the fishtail section is insert moulded onto the tubular section such that the plastic material reinforces a hole in the tubular section and extends radially into the tubular section to define a nut, which mechanically locks the tubular section and the fishtail section together.

3. A composite spout and bag combination according to claim 1 , wherein the fishtail section is made from polypropylene.

4. An aerosol container comprising:

an outer casing comprising a body and cone; and

a composite spout and bag combination, wherein the composite spout has a polymer coated metal tubular section, adapted to accommodate a valve arrangement and a plastic fishtail section, adapted to form a leak-proof seal with the bag, the bag being made from a multilayer film, having a metal foil layer, to provide a barrier, interspersed between plastic layers, to protect the foil and to form a secure bond with the fishtail section, and the fishtail section is insert moulded onto the tubular section.

5. An aerosol container according to claim 4 , wherein the cone is formed integrally with the body to provide a unitary outer casing.

6. An aerosol container according to claim 4 , wherein the bag is filled with a product and a volume defined between the outside of the bag and the inside of the body and cone is pressurised with propellant and sealed by a valve cup and valve.

7. An aerosol container 1 according to claim 5 , wherein the valve includes a dip tube.

8. A method of assembling an aerosol container comprising the steps of:

in an outer casing comprising a body and cone, rolling up longitudinally and inserting a composite spout and bag assembly into the outer casing,

wherein the composite spout has a polymer coated metal tubular section, adapted to accommodate a valve arrangement and a plastic fishtail section, adapted to form a leak-proof seal with the bag, the bag being made from a multilayer film, having a metal foil layer, to provide a barrier interspersed between plastic layers to protect the foil and to form a secure bond with the fishtail section, and the fishtail section is insert moulded onto the tubular section.

9. A composite spout and bag combination for an aerosol container, the combination comprising:

a composite spout, the composite spout comprising:

a polymer coated metal tubular section that is adapted to accommodate a valve arrangement of the aerosol container; and

a plastic fishtail section partially disposed within the polymer coated metal tubular section; and

a bag comprising a multilayer film, the film having a metal foil layer interspersed between plastic layers.

10. A composite spout and bag combination according to claim 9 , wherein the metal tubular section has a base that defines a recess, the plastic fishtail section includes a nut, and the plastic fishtail section is partially disposed within the polymer coated tubular section and secured to the polymer coated tubular section by the nut.

11. A composite spout and bag combination according to claim 10 , wherein the nut is integral with the plastic fishtail section.

12. A composite spout and bag combination according to claim 10 , wherein the fishtail section is made from polypropylene.

13. A composite spout and bag combination according to claim 10 , wherein the fishtail section is insert moulded onto the tubular section.
