A generally hollow preform for making a stretch blow-molded container may include a threaded finish portion; a neck portion depending from the finish portion; a transition portion depending from the neck portion; a main portion depending from the transition portion; and a closed, generally rounded tip portion depending from the main portion. The preform may include stretch ratios with respect to the container including an axial stretch ratio of about 3.0 to 3.5, a hoop stretch ratio of about 5.0 to 5.5, and a total stretch ratio of about 15 to 19.25. In some embodiments, high stretch ratios may be achieved with less material, yielding substantial cost savings.

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).
