Diaper Champ ONE Odorless Diaper Bin is a diaper disposal bin that can be used with ANY trash bag and is specifically engineered to seal odors in. Diaper Champ utilizes a piston mechanism to prevent any odor from escaping whenever you dispose a diaper. No fussy lids or covers, place the nappy straight into the opening at the top, turn the handle, return it back and you're done! The piston pushes the nappy and all the odors into the bin. The bin contents do not get exposed at all, preventing odor leakage. This bin works with ANY bag so you don’t need expensive refill cassettes or cartridges. Not only do you save big on costs (zero cost on plastics refills!), you massively reduce global plastic waste.
