Vacuum tap

24.205.20.241

CT & Eli,

I think that the teat is the point where the vacuum is applied to the bottle once it is sealed. The tap is then closed off by quick application of a flame or high heat.

Nine-pin minis have the vacuum tap at the top. Eight pin octets seem to have the tap at the bottom. It's teat is hidden by the plastic or metal base and the centering pin.

Final high vacuum is achieved by the metal coatings applied to the getter ring or cup. The blast sucks up most remaining O2---at traps it as stable oxides.
