APPARATUS AND METHOD FOR FABRICATING AND FILLING CONTAINERS

摘要

An injection head for the fabrication of a container from a preform. An injection head interfaces with a mouth of the preform to establish fluid communication between a liquid supply and the mouth. The injection head includes an injection valve disposed within an outer shell of the injection head and configured to selectively permit fluid communication through the injection head upon displacement between an opened and a closed position. The injection head also includes an injection head cavity disposed between the injection valve and the outer shell and connected to the liquid supply. A liquid supply control mechanism and a control mechanism of the injection valve's opening allow fluid communication through the injection head. The control mechanism of the injection valve's opening is activated by the liquid under pressure in the injection head cavity when liquid supply is opened.
