• the first part (1) is configured to establish an attachment (1.1) with the container and comprises:
• one or more passage openings (1.2) to allow the contents to flow out of the container,
• first retention means (1.3) for retaining the second part (2), and
• a closure protrusion (1.4);
• the second part (2) comprises:
• second retention means (2.1) intended for establishing the retention with the first retention means (1.3) of the first part (1), and wherein both retention means (1.3, 2.1) allow relative axial movement between the first part (1) and the second part (2) according to a longitudinal direction (X-X′), limited axial movement between two end positions, a first position allowing the dispensing of the contents of the container, and a second position establishing the closure, preventing the contents from flowing out the container, and
• an opening (2.2) to allow the dispensing of the contents of the container in fluid communication with the one or more passage openings (1.2) of the first part (1) and configured to be closed by means of the closure protrusion (1.4) of the first part (1) in the second position;
• and
