Abstract

A method of making 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 method has the steps of sealing the valve to the product delivery device and outer container at respective annular welds or other bonds joining the valve to the product delivery and to the outer container. The welds, or other bonds may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes. Suitable welds include spin welds.

Claims18

Dependent claims

A method of making an aerosol container, said method comprising:

providing a polymeric outer container having a closed end bottom and an open neck longitudinally opposed thereto, a valve and a product delivery device, said valve and said product delivery device being complementary to said open neck,
disposing said product delivery device in said outer container and in contacting relationship with said neck,
disposing said valve at least partially in said outer container and in contacting relationship with said neck and said product delivery device,
spinning said valve relative to said product delivery device to weld said valve to said product delivery device at a product delivery device spin weld,
charging said outer container with propellant, and
spinning said valve relative to said outer container to weld said valve to said outer container at an outer container spin weld, thereby sealing said propellant therein,
wherein said valve has a product delivery device protrusion fitting onto a sealing surface on said product delivery device and an outer container protrusion fitting onto a sealing surface in said outer container, said product delivery device spin weld and said outer container spin weld being formed at said respective protrusions.

A method of making an aerosol dispenser, said method comprising:

providing a polymeric outer container having a closed end bottom and an open neck longitudinally opposed thereto, a polymeric valve and a polymeric product delivery device, said valve and said product delivery device being complementary to said open neck,
disposing said product delivery device in said outer container and in contacting relationship with said neck,
disposing said valve at least partially in said outer container and in contacting relationship with said neck and said product delivery device, wherein said valve has a product delivery device protrusion fitting onto a sealing surface on said product delivery device and an outer container protrusion fitting onto a sealing surface in said outer container,
joining said valve to said product delivery device in fluid tight relationship at an annular product delivery device seal,
charging said outer container with propellant,
charging product into at least one of said outer container and said product delivery device,
joining said valve to said outer container in fluid tight relationship at an annular outer container seal circumscribing said annular product delivery device seal, thereby sealing said propellant therein,
wherein said product delivery device seal and said outer container seal being formed at said respective protrusions,
disposing an actuator on said aerosol dispenser in operable relationship with said valve, whereby said actuator can open said valve as desired by a user, and
decorating said outer container with indicia.

A method of making an aerosol container having a longitudinal axis, said method comprising:

providing a polymeric outer container having a closed end bottom and an open neck longitudinally opposed thereto, a polymeric valve and a polymeric product delivery device, said valve and said product delivery device being complementary to said open neck,
disposing said product delivery device in said outer container and in contacting relationship with said neck,
disposing said valve at least partially in said outer container and in contacting relationship with said neck and said product delivery device, wherein said valve has a product delivery device protrusion fitting onto a sealing surface on said product delivery device and an outer container protrusion fitting onto a sealing surface in said outer container,
sealingly joining said valve to said product delivery device with a product delivery device seal, and
sealingly joining said valve to said outer container at an outer container seal, said outer container seal being radially outboard of said product delivery device seal,
wherein said product delivery device seal and said outer container seal being formed at said respective protrusions.
