METHOD OF FORMING AND SETTING HEADSPACE WITHIN A CONTAINER

摘要

A method for forming and filling a container (12) with liquid, the container (12) being formed from a preform (10) located within a mold (18) and the method utilizing a hydraulic blow molding device (14) that is coupled to a source (15) of the liquid, which is used as the blow molding medium (16), the hydraulic blow molding device (14) having a blow nozzle (44) and a member, the method comprising: extending the member from a retracted position to a position within the preform (10); engaging the blow nozzle (44) in fluid tight communication with an open end of the preform (10) as to provide a sealing engagement of the blow nozzle (44) with the preform (10); injecting the liquid blow medium (16) into the preform (10) so as to form the container (12) after the sealing engagement of the blow nozzle (44) with the preform (10). The member have initiated its advancement into the preform (10) prior to the time of sealing engagement of the blow nozzle (44) with the preform (10).
