Abstract: A float dispenser is adapted to be floated in a body of water such as a swimming pool, to dispense in the water a soluble solid material carried by the dispenser. The dispenser includes a flotation element from which an apertured receptacle is supported below the water. The receptacle is divided into separate compartments. A single tablet of water soluble material is located within each compartment so that the tablet segregated from the other tablets to expose its maximum surface areas to the surrounding water. The dispenser may be made of two identical integral half sections of molded plastic material which are locked together to lock the tablets within their individual compartments. After dissolution of the tablets, the dispenser may be discarded and replaced with another.
