Abstract
A plastic aerosol container (10), an associated preform (10a) and a method of manufacturing the preform (10a) and container (10) is described. The container (10) comprises an adapter (20) that defines an opening (11) of the container (10), the opening (11) being arranged to receive and be sealed by an aerosol valve cap (3). The container (10) also comprises a body 40 that defines an internal volume of the aerosol container (10). The container (10) is blow-moulded from a preform (10a) ideally having a corresponding adapter (20a) and body (40a) which are secured to one another, with an expansion region (45a, 46a) of the body (40a) of the preform (10a) being arranged to be expanded to form the internal volume of the aerosol container (10).
