Get Busy with the Fizzy! (I am definitely showing my age!)
The first opportunity Peterborough-based SodaStream had to carbonate 1 litre of water (rather than the small glass mixer bottles most people remember). It came about with the new wonder material PET, chosen by the client, that allowed a full litre to be pressurised with CO2 at 170psi. So far so good, except that PET shrinks back to its original pre-blown state when put in a dishwasher! So the final production bottles had to be made of expensive Polycarbonate.
Michael's work, as Principal Designer at Roberts Weaver, involved generating concepts, assembly methods and production drawings as well as devising how the new interlock mechanism worked.
