PLUP  Stackable ready-to-drink bottle. Recycable; PET-plastics. PLUP Ltd, Finland. Design: Stefan Lindfors 2008. Photo: Fabian Björk, installation photos: Marco Melander.  The Brief given to Lindfors in 2007: Design a bottle in recyclable plastics for the "ready-to-drink"-category of beverages which has a completely new identity, revolutionary functional innovations and which is possible to manufacture in mass production."  Lindfors' Design Process in his own words: I scanned the functional points of bottles since Coca Cola 1915. A ready-to-drink bottle should stack, it shouldn't fall over easily, it would help if you could easily attach it to your belt or back-pack.  AND it should have strong emotional value from a design perspective. I came up with the "life saver / bagle" idea, and I had naive self-confidence sufficient to believe industrial history could be made here.  The stackable Plup bottle designed by Stefan Lindfors 2007-2008 is manufactured from a clear, durable and recyclable PET-plastic, the volume is 0.4 litres (16 US fl. oz.), and the bottle passed through the EU-return-bottle machines in 2008. The star fish cap is made of an HDPE-plastic.  Lindfors' partner in the 3D computer modeling was Mika Ihanus. The first launch on the Finnish market was on August 4, 2008....
