The luxury claim and upscale aesthetics are leitmotifs in cosmetics packaging and must be convincingly communicated through design, ergonomics and functional aspects. It is, therefore, advantageous if the technical details are resolved intelligently and ergonomically, while leaving the aesthetics unaffected. These requirements have been taken into account and implemented in this refill concept. The thick-walled parts of the packaging are retained; the thin-walled inside part is filled, used, recycled and resold later to be inserted into the outer container once again. The plastic container is thus a sustainable, resource-saving solution. Intuitive handling and a well thought refill concept with contamination protection were considered positive.
