What the jury said:
Krones has once again managed to massively reduce the weight of the 500ml water bottle with the development of the new ShoulderFlex bottle. The new bottle design makes a weight of less than 6 g technically feasible, which means a material saving of up to 50% compared to a standard water bottle on the market. Despite this massive reduction in weight, the bottle achieves a top load of 40kg when full. It is worthy of note that the new bottle achieves this high value without any internal N2 pressure. The bottle is also very stackable.
