Plastics bottle filling station - uses gas under pressure to test bottle for leakage before it is filled with a liq.

摘要

In the filling process, where plastics bottles especially of PET are filled with a liq. at each filling station (2) the container (6) is subjected to a test gas at a pressure to check for leakage, before it is filled with the liq.. Also claimed is a filling machine with at least one control valve (23) at each filling station (2) to insert a gas under pressure into the bottle (6), before filling, to check for leakage. USE/ADVANTAGE - The method is for filling blow moulded plastic bottles with a liq.. The operation ensures that faulty bottles are detected before filling, where impurities in the bottle material can cause leakage in the bottle structure.
