One of the Bang team had an idea of combining a colander with a serving dish. The bowl has a silicon base which can flip down and up. Flip it down to pour pasta, potatoes or wash salads in the sink, then push down on the bowl and the silicon flips up and closes all the holes. You can now add a sauce and serve, and the silicon also acts as a trivet.
We could not believe how challenging this concept was. The silicon had to be designed so as to hold the weight when in inverted, not suction to the bottom of the sink, close the holes and come off and on easily to go in a dish washer.
We added a wave shape to the silicon to prevent suction to the sink. The cross section of the wall thickness varies to enable the silicon to have the strength in downward position but enable it to flip up to close the holes. The bowl itself was shaped to fit the varying wall thickness required and the lips were designed to help you push down as well as hold and serve.
The Colandish was selected and won a German Design Award in 2016, and following trade shows in Ambiente in Germany and Chicago in USA we have signed up distribution for the major markets. It has started a new brand called Michael&Knox which we are now designing new housewares product for.
