Bottles treated to the spiral effect have the choice of creating the ridges perfectly vertical or allow the ridges to curve in order to create a spiral effect.
The effect allows the bottle to still be perfectly smooth on the outside so as to not affect the experience for end customers. Small ridges of material create the effect inside the bottle. These ridges can help to mix contents within the contained solution by acting as a figurative cement mixer while adding an up-market visual aesthetic.
