The Objective

Develop a liquids packaging solution that will allow the automatic elimination of air (head space) from within the bottle in packaging and throughout consumption.

The Solution

A double sided buoyancy valve was developed and incorporated into the capping system. This is applied to a custom made bottle that utilises a concertina for compressibility. The air in the bottle is evacuated as the bottle is compressed. Once the fluid hits the buoyancy valve it rises up and locks off the air vents via the top seal.

When the bottle is released the lower seal is drawn down against the neck of the bottle and stops further air ingress and consequently forms a pneumatic lock. With all oxygen in the bottle evacuated the cap may then be locked for shipping or storage.
