Title (EN) METHOD FOR FORMING AND FILLING A CONTAINER BY MONITORING THE PRESSURE OF LIQUID INJECTED IN THE CONTAINER
(FR) PROCÉDÉ DE FORMATION ET DE REMPLISSAGE D’UN RÉCIPIENT EN SURVEILLANT LA PRESSION D’UN LIQUIDE INJECTÉ DANS LE RÉCIPIENT
Abstract:
(EN) The method comprises: - a first injection step, wherein a first predetermined volume of pressurized liquid is injected into the preform (8), said predetermined volume corresponding to a fraction of the container volume, said first injection step causing an expansion of the preform (8) into a first intermediate container. The method further comprises: - a second injection step, wherein, once the first predetermined volume of liquid has been injected, the liquid injection speed is reduced and the pressurized liquid is further injected in the first intermediate container until a predetermined switch pressure (Pp) in the liquid injection circuit (54) is reached, said second injection step causing an expansion of the first intermediate container into a second intermediate container, and - a third injection step starting once the predetermined switch pressure (Pp) is reached, wherein the liquid injection speed is decelerated until the liquid injection is stopped.
(FR) L’invention concerne un procédé comprenant : une première étape d’injection, dans laquelle un premier volume prédéfini de liquide sous pression est injecté à l’intérieur de la préforme (8), ledit volume prédéfini correspondant à une fraction du volume du récipient, ladite première étape d’injection entraînant une dilatation de la préforme (8) pour former un premier récipient intermédiaire. Le procédé comprend en outre : une deuxième étape d’injection, dans laquelle, une fois le premier volume prédéfini de liquide injecté, la vitesse d’injection de liquide est réduite et le liquide sous pression est ensuite injecté dans le premier récipient intermédiaire jusqu’à ce qu’une pression de commutation prédéfinie (Pp) dans le circuit d’injection de liquide (54) soit atteinte, ladite deuxième étape d’injection entraînant une dilatation du premier récipient intermédiaire pour former un second récipient intermédiaire, et une troisième étape d’injection débutant dès que la pression de commutation prédéfinie (Pp) est atteinte, dans laquelle la vitesse d’injection de liquide est décroissante jusqu’à ce que l’injection de liquide soit arrêtée.
