1. A method comprising in sequence the steps of:
dispensing a continuous polymeric extrudate in a molten state;
separating from the continuous extrudate a dose substantially having the shape of a parallelepiped, the dose having a separation surface at which the dose has been separated from the continuous extrudate, the dose further having a face adjacent to the separation surface;
conveying the dose towards a mould comprising a first mould part and a second mould part;
shaping the dose in the mould by moving the first mould part and the second mould part one towards the other in a moulding direction arranged transversally to said face, thereby obtaining a dispensing part of a container, the dispensing part comprising:
an edge zone;
a neck surrounding a passage through which a product contained in the container can be dispensed;
a membrane which closes the passage, the passage being intended to be opened after
the shaping step, so that said product can flow out,
wherein the method further comprises the step of joining the dispensing part to a container body at the edge zone of the dispensing part;
wherein the passage is opened by removing the membrane in a cutting step performed downstream of the mould and outside the mould, before applying a closing element on the neck,
the cutting step being performed before joining the dispensing part to the container body.
