SUBSTANCE: elongated bottle comprises main part made of sheet metal. Sheet metal has small difference in characteristics between yield point corresponding to yield point of sheet metal and state at ultimate stretching corresponding to tensile strength of sheet metal. Main part additionally comprises a concave lower part having a circular perimeter. Cylindrical part extends from circular perimeter of lower part and has uniform diameter. Neck passes from cylindrical part and has conical profile. Neck can contain threaded part containing thread turns located on outer surface of neck or area for reduction of crown cap.
