METHOD AND APPARATUS FOR PRODUCING A DISPENSING PART OF A CONTAINER, AND DISPENSING PART OF A CONTAINER

A method comprises in sequence the steps of: dispensing a continuous polymeric extrudate (8) in a molten state; separating from the continuous extrudate (8) a dose (14) substantially having the shape of a parallelepiped, the dose (14) having a separation surface (65) at which the dose (14) has been separated from the continuous extrudate (8), the dose (14) further having a face (22) adjacent to the separation surface (65); conveying the dose (14) towards a mould (11) comprising a first mould part (23) and a second mould part (24); shaping the dose (14) in the mould (11) by moving the first mould part (23) and the second mould part (24) one towards the other in a moulding direction (Y) arranged transversally to said face (22), thereby obtaining a dispensing part (2; 102) of a container. The dispensing part (2; 102) comprises: an edge zone (3; 103) suitable for being joined to a container body; a neck (4; 104) surrounding a passage (50) through which a product contained in the container can be dispensed; a membrane (43; 143) which closes the passage (50), the passage (50) being intended to be opened after the shaping step, so that said product can flow out.
