摘要： To solve a problem associated with formation of a transparent window portion in a biaxially stretch blow molded container by a nozzle structure of an injection molding apparatus, provided is a biaxially stretch blow molded container that is formed with a clearly transparent window portion in a longitudinal strip shape by effectively preventing mixture of a colored resin to the window portion. The injection molding apparatus includes in a nozzle portion a longitudinal groove flow path, in which a transparent B resin flows. By, for example, reducing and increasing, respectively, the width and depth of the longitudinal groove flow path on the downstream side, and engraving slits in an inner mandrel and even in a front end portion of a stopper pin, flowability of the B resin in a horizontal direction is enhanced. This ensures that the B resin may be stably laminated in an opaque A resin, in the form of a slit extending beyond a center position of the A resin in a columnar joining flow path located in a front end portion of the nozzle portion.

摘要： Provided is a container production method by liquid blow molding. The method includes a head space forming step of forming a head space (HS) in the upper portion of a container (C), in which, with the container (C) disposed in a cavity (12), a bottom panel portion (Cb11) molded into an upward convex shape on a bottom (Cb1) of the container (C) is inverted by pushing it down with a pushing rod (20) and is plastically deformed into a downward convex shape.

摘要： To solve a problem associated with formation of a transparent window portion in a biaxially stretch blow molded container by a nozzle structure of an injection molding apparatus, provided is a biaxially stretch blow molded container that is formed with a clearly transparent window portion in a longitudinal strip shape by effectively preventing mixture and cut-in of a colored resin to the window portion. In a predetermined range extending from an upstream end to a predetermined downstream position of a flow path including a cylindrical flow path and a reduced-diameter flow path formed in a nozzle portion, a pair of guiding ribs in the form of longitudinal ridges is arranged in line to partition the flow path in a circumferential direction, and a longitudinal groove flow path is formed between the pair of guiding ribs. A molten B resin is supplied to the longitudinal groove flow path, and a molten A resin is supplied to the cylindrical flow path excluding the longitudinal groove flow path. Thus, the longitudinal strip-shaped flow path of the B resin interrupts the cylindrical flow path of the A resin in the circumferential direction.
