Overflow filling focuses on consistent visual fill level, especially for transparent bottles used in cosmetics, cleaning liquids and thin products.
Best for
- Thin liquids in transparent bottles
- Products where shelf appearance matters
- Foamy products that need level control
Not ideal for
- Liquids with particles
- Very viscous liquids

Filling principle
The nozzle fills to a target level and excess liquid returns to the tank. This gives bottles a consistent visual line even when container volume varies slightly.
