Patent number: 9802729Abstract: A blow molding method includes a primary blow molding step that molds a preform (200) in a primary blow mold (300A) that includes a primary temperature control section (330) to obtain an intermediate molded article (202), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article (204) that has shrunken in a secondary blow mold that includes a secondary temperature control section (430) to obtain a final molded article. The primary blow molding step cools a first intermediate molding region of the intermediate molded article that follows a neck using a first primary temperature control section, and the shrinkage step shrinks a second intermediate molding region of the intermediate molded article of which the temperature is controlled by a second primary temperature control section.Type: GrantFiled: February 13, 2013Date of Patent: October 31, 2017Assignee: NISSEI ASB MACHINE CO., LTD.Inventors: Masayuki Usami, Hiroyuki Tsukamoto, Kazuyuki Yokobayashi, Yoichi Tsuchiya

Patent number: 9656419Abstract: In one embodiment of this invention, a blow nozzle, which introduces blow air into a molded article in which a flange portion is supported by a blow cavity mold, includes a nozzle main body and an outer nozzle. The outer nozzle includes a first surface brought into press contact with the flange portion and a second surface disposed further outwards in a radial direction than the first surface and being brought into contact with the blow cavity mold. From when the nozzle main body is moved and the first surface is brought into contact with the flange portion to when the second surface is brought into contact with the blow cavity mold and the movement of the nozzle main body is stopped, the first surface of the outer nozzle is overdriven so that the flange portion is airtightly sealed by the first surface.Type: GrantFiled: August 5, 2013Date of Patent: May 23, 2017Assignee: NISSEI ASB MACHINE CO., LTD.Inventors: Kazuyuki Yokobayashi, Daizaburo Takehana, Fumiyuki Nakazawa
