Method of degasification of a carbonated beverage-filled container

A method of degasification of a carbonated beverage-filled container in an apparatus for blowing and filling containers, the apparatus comprising:

• a mold enclosing a blown and carbonated beverage-filled container, the container including a dispensing opening,
• an injection head that is movable along a longitudinal axis passing by the dispensing opening of the container between a sealing position in which the injection head is in a sealing engagement with the dispensing opening and a plurality of non-sealing positions in which the injection head is at a distance from the dispensing opening, the method comprises the steps of:
• starting from a sealing position of the injection head with one of the mold and the container;
• moving the injection head away from the sealing position to a first non-sealing position degasifying the carbonated liquid in the container;
• after moving the injection head to the first non-sealing position, returning the injection head back to the sealing position;
• and
• after returning the injection head back to the sealing position, moving the injection head away from the sealing position to a second non-sealing position relative to the container;
• and
• removing the container from the mold.
