Glossary
Carbonated filling glossary for buyers.
Understand the technical words used when specifying a carbonated drink filler, bottle line, can line or complete pressure-controlled filling route.
| Counter-pressure filling | A filling method where the package is pressurised before product enters, helping reduce CO₂ breakout and foam. |
|---|---|
| Isobaric filling | A closely related term for filling where the container and product are kept at a controlled pressure balance during the fill. |
| Fill valve | The controlled product and gas pathway that manages purge, pressure, product flow and venting. |
| Snifting | A controlled pressure-release step used after filling so the pack can be removed or passed to closing with less foam risk. |
| DO | Dissolved oxygen in the liquid. It matters most where the product is oxygen-sensitive, such as beer, cider or some RTDs. |
|---|---|
| TPO | Total packaged oxygen. It normally considers oxygen in the liquid and package headspace after filling and closing. |
| Carbonation volumes | A way of describing how much CO₂ is dissolved in the product; the confirmed target should come from the drink specification or a measured sample. |
| Headspace | The space left above the liquid after filling. Its correct size depends on the product, package and closure requirement. |
- A crowner applies crown caps to suitable glass bottles.
- A screw capper or ROPP capper must match the bottle finish and closure design.
- A can seamer closes filled cans using the specified can end and seam setup.
- CIP means cleaning-in-place where the machine design and process allow it; manual cleaning or strip-down may still be required on some routes.
Buyer questions
Questions buyers ask about this topic.
Is counter-pressure the same as isobaric filling?
The terms are closely related in buyer language because both refer to filling under controlled pressure. The exact machine sequence and valve design should be checked from the equipment specification.
Why does Lancing ask for carbonation and temperature details?
Carbonation and temperature affect foam, filling stability and the pressure route, so they help Lancing select a realistic machine and trial approach.
Does every enquiry need DO or TPO targets?
No. DO and TPO targets are most useful when the drink is oxygen-sensitive and the buyer has a suitable measurement method or acceptance requirement.
