Title
(EN) BLOWING STATION AND METHOD FOR FORMING A FREE BLOW CONTAINER
(FR) POSTE DE SOUFFLAGE ET PROCÉDÉ DE FORMATION D'UN RÉCIPIENT SOUFFLÉ SANS CONTRAINTE
Abstract
(EN)
An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity (116, 16) is provided. A pressure source (120, 20) includes an inlet (146, 150, 46, 50) and a piston-like device (140, 40). The piston- like device (140, 40) is moveable in a first direction wherein liquid is drawn into the pressure source (120, 20) through the inlet (146, 150, 46, 50) and in a second direction wherein the liquid is urged toward the preform (112, 12). A blow nozzle (122, 22) may be adapted to receive the liquid from the pressure source (120, 20) and transfer the liquid at high pressure (P2) into the preform (112, 12) thereby urging the preform (112, 12) to freely expand until an unopened end thereof contacts a platen (118). The platen (118) forms a bottom in a resultant container. The liquid remains within the container as an end product.
(FR)
L'invention concerne un appareil et un procédé pour former et remplir simultanément un récipient en plastique sans l'utilisation d'un moule formant une cavité de moule (116, 16). Une source de pression (120, 20) comprend une entrée (146, 150, 46, 50) et un dispositif de type piston (140, 40). Le dispositif de type piston (140, 40) est mobile dans une première direction dans laquelle un liquide est amené par aspiration dans la source de pression (120, 20) à travers l'entrée (146, 150, 46, 50) et dans une seconde direction dans laquelle le liquide est poussé vers la préforme (112, 12). Une buse de soufflage (122, 22) peut être conçue pour recevoir le liquide en provenance de la source de pression (120, 20) et à transférer le liquide sous haute pression (P2) dans la préforme (112, 12) en contraignant ainsi la préforme (112, 12) à se dilater librement jusqu'à ce qu'une extrémité non ouverte de celle-ci entre en contact avec un plateau (118). Le plateau (118) forme un fond dans un récipient obtenu. Le liquide reste à l'intérieur du récipient pour constituer un produit fini.
