SHAPED METAL CONTAINE AND METHOD FOR MAKING A SHAPED METAL CONTAINER

摘要

The present invention relates to a method for making a shaped metal container (1), comprising a container middle section (3-5) having at least one middle section diameter (Dm i ), which container middle section (3-5) is connected at one end to a container bottom section (6) having at least one bottom section diameter (Db), and at the other end connected to a container top section (10) having a container opening (14), and having at least one top section diameter (Dt),
comprising the steps of:
i) providing a container preform (25) having a cylindrical body (26) with a diameter (Dc);
ii) inwardly shaping by necking at least a section (28) of the cylindrical body (26); and
iii) outwardly shaping at least a section of the cylindrical bodyb (26),
wherein at least a section to be inwardly or outwardly shaped is annealed,
such that at least one of the middle section diameter( Dmi), the bottom section diameter (Db), and the top section diameter (Dt) is greater than, and at least one of the middle section diameter (Dmi), the bottom section diameter (Db) and the top section diameter (Dt), is smaller than the cylinder diameter (Dc) of the container perform (26), and to the shaped metal container (1).
