Title (EN) LIQUID BLOW MOLDING APPARATUS AND PREFORM
(FR) APPAREIL ET PRÉFORME DE MOULAGE PAR SOUFFLAGE D'UN LIQUIDE
(JA) 液体ブロー成形装置及びプリフォーム
Abstract:
(EN) A liquid blow molding apparatus (10) is configured by being provided with, at the lower end of a cylindrical nozzle (17), a seal surface (17c) that, when the nozzle (17) is inserted into an inlet (2), abuts, from the axial direction, on a stepped surface (5) provided on an inner peripheral surface of a preform (1), so as to seal an area between the nozzle (17) and the inner peripheral surface of the preform (1). In addition, the preform (1) is configured by being provided with, on the inner peripheral surface thereof, the stepped surface (5) on which the seal surface (17c) of the nozzle (17) abuts from the axial direction. The stepped surface (5) is formed into a tapered shape in which the radially inner side is located above the radially outer side.
(FR) L'invention concerne un appareil (10) de moulage par soufflage d'un liquide conçu en ce qu'il présente, au niveau de l'extrémité inférieure d'une buse cylindrique (17), une surface d'étanchéité (17c) qui, lorsque la buse (17) est introduite dans une entrée (2), vient en butée, à partir de la direction axiale, sur une surface étagée (5) disposée sur une surface périphérique interne d'une préforme (1), de manière à fermer hermétiquement une zone entre la buse (17) et la surface périphérique interne de la préforme (1). De plus, la préforme (1) est conçue en étant pourvue, sur la surface périphérique interne correspondante, de la surface étagée (5) sur laquelle la surface d'étanchéité (17c) de la buse (17) vient en butée contre la direction axiale. La surface étagée (5) est formée en une forme effilée dans laquelle le côté radialement interne est situé au-dessus du côté radialement externe.
(JA) 液体ブロー成形装置(10)を、円筒状のノズル(17)の下端に、ノズル(17)が口部(2)に挿入されたときに、プリフォーム(1)の内周面に設けられた段差面(5)に軸方向から当接してノズル(17)とプリフォーム(1)の内周面との間を密封するシール面(17c)を設けた構成とする。また、プリフォーム(1)を、その内周面に、ノズル(17)のシール面(17c)が軸方向から当接する段差面(5)を備えた構成とする。段差面(5)を、径方向外側よりも径方向内側が上方に位置するテーパー状に形成する。
