Title (EN) CONTAINER MADE OF POLYESTER RESIN AND METHOD FOR MOLDING THEREOF
(FR) RÉCIPIENT RÉALISÉ EN RÉSINE DE POLYESTER ET SON PROCÉDÉ DE MOULAGE
(JA) ポリエステル樹脂製容器及びその成形方法
Abstract:
(EN) The object is to develop a container made of a polyester resin which is sufficiently applicable to a retort processing at a temperature exceeding 120ºC and up to about 130ºC, and to provide a container made of a polyester resin which can achieve the improvement in productivity or quality of retort foods and a method for producing the container. The object can be achieved by a double blow molding process which comprises a primary blow molding step in which a preform is subjected to biaxial stretching blow molding to form a primary intermediate molded article, a step in which the primary intermediate molded article is heated to shrink-mold the article into a secondary intermediate molded article, and a secondary blow molding step in which the secondary intermediate molded article is blow-molded into the shape of a container. In the secondary blow molding, the mold temperature exceeds 210ºC.
(FR) L’objet de l’invention consiste à développer un récipient réalisé en résine de polyester qui peut s’appliquer à un procédé de stérilisation à une température supérieure à 120 °C et jusqu’à environ 130 °C, et à fournir un récipient réalisé en résine de polyester qui peut permettre d’améliorer la productivité ou la qualité d’aliments stérilisés. L'invention concerne également un procédé pour la fabrication du récipient. L’objet peut être réalisé selon un procédé de moulage par soufflage double qui comprend une première étape de moulage par soufflage dans laquelle une préforme est soumise à un moulage biaxial par soufflage et étirage destiné à former un premier article moulé intermédiaire qui est chauffé pour mouler par rétraction l’article pour former un second article moulé intermédiaire, et une seconde étape de moulage par soufflage pendant laquelle le second article moulé intermédiaire est moulé par soufflage pour acquérir la forme d’un récipient. Lors du second moulage par soufflage, la température du moule dépasse 210 °C.
