Method for producing tubular containers

Process for producing containers (23) by separately producing a preform (1) including a neck (4) having final dimensions and a tubular body (2) having smaller dimensions than the intended final form, heating the preform (1), fitting the preform (1) to a drawing head (9b) in the neck region, introducing the preform (1) together with the drawing head (9b) into the interior of a multi-part closable blow mould (16a;

• 16b), axial drawing of the preform (1) by means of the drawing head (9b) and expanding the preform (1) by supplying blowing air into the interior, hardening the container closely fitting against the wall of the blow mould (16a;
• 16b), opening the blow mould and removing the container, characterised in that for producing a tubular container (23) the preform (1) comprises a closure at the one end and an open filling opening (3) with an externally situated, projecting flange (6) at the other end and that the preform (1) is connected to the drawing head (9b) in a rotatable manner relative to one another, the supply of blowing air taking place by means of a blow nozzle (17) arranged in a sealed manner at the open end of the filling opening (3) and that the incompletely inflated or, respectively, stretched lower end portion (19) of the produced container (23) is separated off or cut to length.
