Abstract
(EN)
A method for producing a resin container having an injection-molding step (S1) for injection molding a resin preform (300) having a bottom and a blow-molding step (S3) for blow molding the preform (300) to produce a resin container, wherein the injection-molding step (S1) includes a filling step for filling a cavity formed by at least an injection core mold (102) and an injection cavity mold (104) with molten resin to form the preform (300) and forms a first groove (144) extending from a bottom-defining portion (112) to a neck-defining portion (132) on the surface of a body-defining portion (122) of the injection core mold (102).
(FR)
L'invention concerne une méthode de fabrication d'un récipient en résine ayant une étape de moulage par injection (S1) pour le moulage par injection d'une préforme en résine (300) ayant un fond et une étape de moulage par soufflage (S3) pour le moulage par soufflage de la préforme (300) pour produire un récipient en résine, l'étape de moulage par injection (S1) comprenant une étape de remplissage pour remplir une cavité formée par au moins un moule à noyau d'injection (102) et un moule à cavité d'injection (104) avec de la résine fondue pour former la préforme (300) et formant une première rainure (144) s'étendant d'une partie de définition de fond (112) à une partie de définition de col (132) sur la surface d'une partie de définition de corps (122) du moule à noyau d'injection (102).
(JA)
樹脂製の有底のプリフォーム(300)を射出成形する射出成形工程(S1)と、プリフォーム(300)をブロー成形して樹脂製容器を製造するブロー成形工程(S3)と、を有する樹脂製容器の製造方法であって、射出成形工程(S1)は、少なくとも射出コア型(102)および射出キャビティ型(104)によって形成されるキャビティ内に溶融樹脂を充填してプリフォーム(300)を形成する充填工程を含み、射出コア型(102)の胴部規定部(122)の表面に、底部規定部(112)からネック部規定部(132)へ延びる第1の溝(144)が形成されている、樹脂製容器の製造方法。
