A method and apparatus for producing a pet bottle with the exception of the mitt strength bottle neck

摘要

For the manufacture of a P.E.T. bottle with an off-centre neck, a preform is heated and its body is slightly angled with respect to its neck by sideways displacement. The preform (4) is inserted in a blowing mould (5). A tilted stretching rod (1) is advanced into the preform at the same time as it is blown to shape in the mould. The finished bottle has its neck off-centre with respect to the rest of the bottle.
