Folder/collection sheet «Swiss inventions - Toilet Duck»

When Walter Düring-Orlob wanted to name his new product “Toilet Duck”, he was advised against it. But he stuck by his idea, applied for a patent and even made a TV commercial. It has achieved huge success! Since its market launch in 1980, Toilet Duck has become indispensable in Swiss bathrooms – and a long-standing export hit. The spirit of innovation ran in the family: Walter’s mother Maria Düring-Keller developed the famous “durgol” descaler, laying the foundation for the family business. When Walter joined, he was working on the practical plastic bottles. He kept wondering how a cleaning product could be squirted effortlessly under the toilet rim. The answer was a curved bottleneck reminiscent of a duck. Incidentally, the first recipe for the cleaning product came from his wife Vera Düring.
