摘要
The invention concerns a pressurised aluminium alloy container dispensing under pressure products ranging from liquid to pasty having a base (1) whereof the central part (2) is bored with an orifice (3) designed to be closed with a Nicholson-type nozzle (10), wherein said central part (2) of the base (1) comprises a spherical portion (S), whereof the concavity is oriented downwards, and the three toric portions have a concavity oriented upwards (A), downwards (B) and upwards alternately. The portions are tangentially connected to one another, the connection point (L, M, N) being a inflection point. The slope at point M is substantially horizontal. The last toric portion (C) has a thickness wall (4) whereof the lower angle (5) delimits said orifice (3) and the inclination ranges between 30 DEG and 60 DEG . The method for making such a container base comprises three additional steps whereby the base (1) central part (2) is preformed, bored and subsequently formed.
