Abstract

1453204 Blow-moulding OWENS-ILLINOIS Inc 2 Oct 1974 [3 Oct 1973] 42724/74 Heading B5A A hollow article having one or more convexities in its peripheral surface is produced by forming a preform having one or more concavities in its peripheral surface, enclosing the preform in a blow-mould so that the or each concavity in the preform is aligned with part of the cavity which is to form a convexity in the article and blow-moulding the preform. As shown, a preform of cruciform section having convex portions 37, Fig. 7, to form the sides of the article and concave portions 36, to form the corners of a square-section article is formed by blow-moulding in a preform blow-mould (20, Figs. 1-4, not shown) from a tubular parison itself formed by extrusion- or injection-moulding. The blown preform is blow-moulded in the final blow-mould 41. The final article has walls of uniform thickness or, alternatively, the corners may have an increased wall thickness. Figs. 11-14 (not shown) show the formation of a bottle of oval section and Figs. 15-16 (not shown) a bottle having projecting portions.
