    • Method of blow moulding a container from a hollow, elongated parison of a thermoplastic material, wherein the method comprises: - arranging the parison in a closed moulding equipment comprising a moulding cavity and at least one aperture, wherein the at least one aperture provides an opening into the moulding cavity from outside the closed moulding equipment, wherein the circumference of the at least one aperture is larger than or equal to a circumference of the parison, such that a first section of the parison is arranged inside the moulding cavity, a second section of the parison is arranged within the at least one aperture and a third section of the parison is arranged outside the closed moulding equipment, - closing a shutter system around the third section of the parison, thereby pinching the parison and providing a closed volume inside the first and second sections of the parison, - arranging a blow conduit in fluid communication with the closed volume inside the second section of the parison, - blowing pressurised gas from the blow conduit into the first and the second section of the parison, thereby forming first and second blow moulded sections, wherein the first blow moulded section is the container, and - separating the second blow moulded section from the first blow moulded section, thereby providing an opening in the container.
    • 从热塑性材料的中空细长型坯吹塑容器的方法,其中所述方法包括:将所述型坯布置在包括模制腔和至少一个孔的封闭模制设备中,其中所述至少一个孔提供开口 从封闭的模制设备的外部进入模制腔,其中至少一个孔的圆周大于或等于型坯的圆周,使得型坯的第一部分布置在模制腔内部,第二部分 型坯布置在所述至少一个孔内,并且型坯的第三部分布置在封闭的模制设备的外部, - 围绕型坯的第三部分封闭快门系统,从而夹紧型坯并在型坯内部提供封闭的体积 型坯的第一和第二部分, - 布置与第二部分内的封闭体积流体连通的吹塑导管 在型坯中,将来自吹塑导管的加压气体吹入型坯的第一和第二部分,从而形成第一和第二吹塑部分,其中第一吹塑成型部分是容器,并且将第二吹塑成形部分 从第一吹塑成型部分,从而在容器中提供开口。
