Abstract

A method of degasification of a carbonated beverage-filled container in an apparatus for blowing and filling containers, the apparatus including a mold enclosing a blown and carbonated beverage-filled container. The container includes 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 non-sealing position in which the injection head spaced from the dispensing opening. The method includes the steps of moving the injection head away from the sealing position to a first non-sealing position, moving the injection head from the first non-sealing position back to the sealing position, and after moving the injection head back, moving the injection head away from the sealing position to a second non-sealing position that is different from the first non-sealing position.

First claim

What is claimed is:

1. 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.

2. The method of claim 1 , further comprising the step of, after moving the injection head to the second non-sealing position, moving the injection head further away from the sealing position to a third non-sealing position and at a higher velocity than the step of moving the injection head to the first non-sealing position.

3. The method of claim 2 , wherein the step of moving injection head to the third non-sealing position is performed by controlling a supply of fluid to a fluid-operated actuator through s secondary valve.

4. The method of claim 1 , wherein the first non-sealing position is at a first distance from the sealing position that is shorter than a second distance from the sealing position to the second non-sealing position.

5. The method of claim 1 , wherein each step of moving the injection head comprising controlling at least one actuator the actuation of which causes the injection head to move accordingly.

6. The method of claim 5 , wherein the at least one actuator is a fluid-operated actuator which actuates the injection head and controlling the actuator comprises a sub-step of controlling the supply of fluid to the actuator.

7. The method of claim 6 , wherein the sub-step of controlling the supply of fluid to the fluid-operated actuator comprises controlling a main valve and a secondary valve.

8. The method of claim 7 , wherein moving of the injection head is performed by controlling the supply of fluid to the fluid-operated actuator through the main valve.
