Diaper Champ nappy pail - The original. The Diaper Champ is an odour-proof nappy pail that can be filled with simple, commercially available waste bags and therefore does not require expensive refill cassettes. Easy to use: insert the nappy into the opening and turn the head section (handle to the other side) until the nappy falls into the bin liner - done. Odour-tight. Simple one-handed operation. Hygienic due to closed system. Inserting the bag: 1. unlock the head section with the coloured button on the front and open the bucket. 2. insert the bag through the opening of the retaining ring. 3. wrap the bag around the retaining ring. Make sure that the fastener remains free. 4. close the head section. A clear click must be audible. Removing the bag: 1. unlock the head section with the coloured button and open the bucket with the handle of the retaining ring. The bag is pulled up so that it is odour-tight. 2 For odourless removal, grasp the bag with one hand under the bag holder. 3. unlock the retaining ring with the coloured button and then dispose of the bin liner.
