The research conducted for the EvoLight 1.5l started from designing a grapping area which usually, due to high carbonation, gets deformed and becomes cylindrical. A solution often used to avoid such deformation is a very narrow grip area with spiral ribs, which avoids the increase of volume due to the internal pressure. The R&D Department has developed an innovative structure, which alternates rigid rib areas with flat areas to discharge the force. This structure, when repeated alternatively over a number of vertical sections, prevents the radial deformation and, at the same time, avoids any collapse along preferential directions.
This structure has also allowed an extreme light-weighting of the bottles, reaching record weights of 18.9 g for the still version and 22.5 g for the sparkling one.
This light-weighting is also possible thanks to the use of the new 26/22 neck finish, developed by Husky Injection Molding Systems, suitable for both still and sparkling water products. The bottle design, together with this interchangeable 26/22 neck finish, permits having the same container for both still and sparkling products, with the advantage of being able to create a corporate shape instantly recognisable on the shelves.
Evolight 1.5 l will be presented at Drinktec 2013 at booth 309, hall B3.
