Abstract
A dispenser for an aqueous solution of a chemical, such as potassium permanganate, that should be confined at all times encloses the chemical in a lightweight disposable jar. The dispenser is actuated by a valve that has a relatively large float on one end of a stem and a diaphragm at the other end of such stem. It is not necessary for the user of the chemical to ever remove it from the container in which it is sold.
