Abstract

L'invention concerne un récipient (1) pour liquides et un procédé de fabrication d'un récipient (1) accueillant des liquides, en particulier des boissons liquides comme la bière, les boissons non alcoolisées et le vin, qui est constitué d'une enveloppe métallique (2) extérieure, pourvue d'anneaux ou de jables formés du côté tête et/ou pied, et d'une bulle (3) disposée dans celle-ci, réalisée en matière synthétique thermoplastique, notamment en PET, qui présente pour le remplissage avec le liquide un raccord (10) avec ouverture fermable pour d'une part un gaz comprimé et d'autre part le liquide. Lors d'une première étape, une ébauche tubulaire est transformée en une enveloppe (2) avec dans sa région médiane (4) une forme adaptée au profil extérieur de la bulle (3) et une transition d'étranglement (5a, 5b) en retrait par rapport à celle-ci, lors d'une deuxième étape, la bulle (3) est insérée dans l'enveloppe (2) et, lors d'une troisième étape, une pression préliminaire est amenée par le raccord (10) dans la bulle (3), pression préliminaire qui presse la bulle contre la transition d'étranglement préprofilée (5a, 5b) de l'anneau de tête et/ou de pied (6a, 7a) et qui presse par contre la bulle avec une surmesure (a) contre la forme préprofilée de la région médiane (4).
