摘要:
The apparatus for forming a container from a container preform comprises: a housing (26); a mold cavity; and a nozzle system (22) disposed in said housing and operably connectable to the mold cavity, said nozzle system being positionable between a first position engaging said housing along an interface of contact (76) preventing pressurized liquid from being injected into the container preform and a second position spaced apart from said housing permitting pressurized liquid to be injected into the container preform, said nozzle system (22) having a tip portion (32, 82), said tip portion being positionable within the container to displacement a predetermine volume of liquid to define a predetermined head space with the container after filling.

The method and the device are used for blow-molding containers. A preform made of a thermoplastic material is first subject to a thermal conditioning operation along a transport path in the region of a heating section. Thereafter, the preform is formed into the container inside a blowing mold by applying blowing pressure. While the preform is shaped into the container, at least one parameter (49, 50) characterizing the shaping is measured and evaluated by a control unit. Depending on said evaluation, at least one controlled variable (48, 46) influencing the shaping operation inside a closed loop is varied in order to match the measured parameter to an associated target value. In this way, it becomes possible to subject the container parison developing during the blow-molding operation to a predetermined defined development.

Disclosed are a method for operating a container handling installation and a container handling installation. The container handling installation comprises at least one container handling device with at least one first functional element (6). The first functional element (6) comprises a first drive for at least one first working function of the first functional element (6) during active container handling mode (AM). The container handling installation further comprises at least one second functional element (11). The first functional element (6) comprises at least one first actuation element (7) and, in a first active container handling mode (AM), is set such that the first actuation element (7) performs no function on the second functional element (11). For a second active container handling mode or for a third replacement mode (WM), the at least one first functional element (6) is moved and/or re-positioned or adjusted by the first drive such that the first actuation element (7) triggers or activates a function of the second functional element (11) through contact with the at least one second functional element (11) of the container handling installation.
摘要:
An apparatus for forming a container from a container preform. The apparatus includes a housing, a mold cavity, and a nozzle system disposed in the housing and operably connectable to the mold cavity. The nozzle system is positionable between a first position engaging the housing along an interface of contact preventing pressurized liquid from being injected into the container preform and a second position spaced apart from the housing permitting pressurized liquid to be injected into the container preform. The nozzle system further includes in some embodiments a seal portion having a first surface—the first surface engaging a second surface extending from the housing in the first position.
