What a fab funky item + yellow too = my color.
Please let me know when you offer it for sale - it could be my first perfume bottle !
I've managed to find about 20 Ekenas items online but non of them like this and only one not signed.
Lake could have designed this as he was there so long but he seems better known for his engraved designs and mottled bi-colour vases. This is the most modern looking piece I've found by him - also signed http://www.antikportal.dk/?page=antique_doc&id=157&lang=dk#
There were other designers but mostly for short periods - maybe freelance. If by one of those, that could also explain why it's not signed, the company prefering to promote only themsleves and their in-house designers.
