Phial Packaging Laminar Air Flow Sterility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current phial packaging apparatuses fail to maintain a constant, laminar air flow over the upper edges of phials during filling and closing operations, leading to turbulence and contamination risks, which violate sterility and cleanliness standards for pharmaceutical products.
Innovation Solution
An apparatus with a conveying line that includes a filling station, a closing station, and two air flow generators: one generating a horizontal laminar flow in the first sterile chamber to affect the phial edges during filling and closing, and another generating a vertical laminar flow in the second sterile chamber to maintain sterility throughout the phial's transport and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filling and closing devices are used to process phials, then productivity is improved, but the devices shield the laminar air flow and create turbulence near the phials transporting path
Solution Approach 1:
The air flow generator is positioned above the phial conveyor and directs air flow vertically downward onto the phials. This vertical dimension of air flow application allows the filling and closing devices to operate horizontally without interfering with the air flow path, thus maintaining laminar flow stability while enabling productive processing operations.
2Manufacturing precision
If filling and closing devices are positioned to process phials, then manufacturing precision is improved, but residual particles are moved from conveyor and operating stations surfaces
Solution Approach 1:
The air flow generator creates a controlled downward air current that serves dual purposes: it maintains the sterile environment by preventing particle settlement on phials, and simultaneously directs potential contaminants away from the phial opening toward the closing station area, converting the harmful particle movement into a controlled containment strategy.
3Reliability
If a constant vertical top-down laminar air flow is generated, then sterility is improved, but the air flow reaches the phials mouth only when they are moving toward the filling station and between filling and closing stations
Solution Approach 1:
The air flow generator is positioned to provide continuous downward air flow coverage over the entire phial processing area, ensuring that the sterile air current is constantly present during all operations including filling, closing, and transit between stations, eliminating gaps in protective coverage.

AI summary
The method for packaging of phials in a sterile environment comprises, subsequently: moving of each empty phial (1), according to a forwarding direction (K), from an input section toward a filling station (R); inserting of a dosed quantity of pharmaceutical products (F) inside the phial (1); transporting the filled phial (1) toward a closing station (8); closing said phial (1). It is moreover provided that a first laminar flow (H) of sterilized air, having a horizontal direction, is applied at least to the upper edges (1h) which define corresponding input mouths of the phials (1), at least during the aforesaid phases of filling and closing of phials (1), as well as during their transfer from the filling station (R) to the closing station (8).
