Container Moulding Tube Separation for Low-Contamination Filling

The patent applies preliminary action by collapsing the parison into a compact configuration before the cutting operation. This collapse reduces the opening size and creates a protected environment for the container interior, preventing contaminants generated during cutting from entering the container. The collapse is performed as a preparatory step before filling and sealing, thereby eliminating the contamination pathway while maintaining production efficiency.

The patent employs dynamics by making the parison configuration changeable - it transitions from an open, extended state during cutting to a collapsed state during filling. This dynamic transformation allows the system to optimize for different operational phases: the collapsed state minimizes cutting path and time, while the open state enables filling pipe insertion. The parison can be dynamically adjusted between these configurations to meet different process requirements.

The patent implements continuity of useful action by producing a continuous container chain from a single mould pair rather than producing individual containers sequentially. The container chain emerges continuously from the mould, and subsequent separation and handling operations process this continuous flow. This approach maintains high productivity through continuous production while eliminating the need for multiple mould pairs, thereby reducing device complexity and investment costs.

The patent applies segmentation by producing containers as a chain that is subsequently separated into individual units. The container chain is formed as a segmented structure where individual containers are connected in sequence, allowing them to be produced efficiently in bulk and then separated as needed. This segmentation approach enables large-volume production while using a single mould pair, and the separating device becomes a simple post-processing element rather than a complex integrated system.
