Method of forming and setting headspace within a container
10363699 · 2019-07-30 · ·

A method for forming and filling a container with liquid. The container being formed from a preform located within a mold and the method utilizing a hydraulic blow molding device that is coupled to a source of the liquid, which is used as the blow molding medium. The hydraulic blow molding device has a blow nozzle and a member that is extended from a retracted position to a position within the preform. A blow nozzle engages in fluid tight communication with an open end of the preform so as to provide a sealing engagement of the blow nozzle with the preform. The liquid blow medium is injected into the preform so as to form the container after sealing engagement of the blow nozzle with the preform. The member initiates its advancement into the preform prior to the time of sealing engagement of the blow nozzle with the preform.

Container treatment plant and method for displacing a valve or a diverting unit of a container treatment plant

A container treatment plant and a method for displacing an element of a valve or a diverting unit of a container treatment plant. The container treatment plant comprises at least one element for treating containers. The element is part of a valve or a diverting unit. The container treatment plant also comprises a displacing unit for displacing the element between a first position and a second position, wherein the displacing unit comprises a magnetically operating actuator such that a rotary motion caused by the actuator displaces the element with the aid of a mechanism between its first and second positions.
