Patent

CA 2430960

The invention relates to a method for the production and filing of containers (12), whereby at least one tube (3) of plastified plastic material is extruded into an open mould (6), the tube (3) is bonded at the advancing end thereof on closing the mould (6) to give the container base and the tube (3) is severed above the mould, by a separating element (21) to give a filling opening. The mould (6) with the tube (3), comprising a filling opening, is moved to a filling position, in which the container is filled after the above is formed in the mould by means of generating an expanding pressure gradient acting on the tube (3). During the movement of the mould (6) into the filling position the filling opening of the tube (3) is covered by means of a sterile barrier (23).

L'invention concerne un procédé de fabrication et de remplissage de récipients (12). Selon ce procédé, au moins un tuyau (3) en matière plastique plastifiée est extrudé dans un moule ouvert (6). Ce tuyau (3) est soudé au niveau de son extrémité avançante lors de la fermeture du moule (6) pour la formation du fond du récipient. Le tuyau (3) est sectionné au-dessus du moule (6) à l'aide d'un élément de sectionnement (21) pour la formation d'un orifice de remplissage. Ce moule (6) est ensuite déplacé dans une position de remplissage, l'orifice de remplissage du tuyau (3) étant ouvert, position dans laquelle le récipient est rempli, après avoir été conçu par la création, dans ledit moule (6), d'un gradient de pression agissant sur le tuyau de manière à élargir ce dernier. Pendant le déplacement du moule (6) en position de remplissage, l'orifice de remplissage du tuyau (3) est recouvert d'une barrière stérile (23).
