Competition: Dezeen has teamed up with German design label L&Z to give away five colourful multipurpose containers by Michel Charlot that fold to different heights depending on the needs of the user.

Congratulations to the winners! Andrew Cardwell from Chile, Zuzana Pavlaninova from the Netherlands, Elizabeth Walsh from the USA, Inbar Meital from Israel and Juliana Santos from Brazil.

Each of the Roll-Up Bins is packaged in a thin cardboard tube similar to a bin bag, and can be unfurled when removed from this container.

Available in a range of simple block colours, the bins can hold between 10 and 30 litres of contents and fold up or down allow them to be adapted for different uses including a bin for waste, a plant pot, a toy basket or a general container.

When unfolded, the bins have the appearance of neatly folded, glossy, thick plastic bags formed into slightly skewed pots.

These can be extended or shortened by the user, or rolled up again for easy storage when not in use.

Although flexible, each Roll-Up Bin is cast from tough, PVC-free TPU plastic and can free-stand securely on the ground. They are also completely waterproof.

Established in 2011, Berlin-based L&Z specialises in developing and manufacturing products for the work place.

Industrial designer Michel Charlot graduated from the ECAL school of art and design in Lausanne in 2009, where he now teaches. In 2011, Charlot set up his own practice and has since designed for NAVA Design, Belux, Vitra and L&Z.

Charlot's U-turn spotlight lamp, designed in collaboration with Belux, was awarded the 2014 Design Preis Schweiz – a Swiss design award for industrial products.

This competition is now closed. Five winners will be selected at random and notified by email. Winners' names will be published in a future edition of our Dezeen Mail newsletter and at the top of this page. Dezeen competitions are international and entries are accepted from readers in any country.
