We worked with a leading chemical cleaning and distribution service provider to develop an innovative chemical bottle cap system. The product makes use of a one-way valve which promotes safe use, reducing the risk of contamination, waste and pilferage. The valve ensures that chemical concentrate can only be dispensed from the attached bottle when fitted to the appropriate dilution and dispensing system, reducing the users’ exposure to the hazardous chemicals. A ratcheting attachment system ensures the cap cannot be removed once fitted.
