Abstract
An apparatus for dissolving and delivering a solution of a solid chemical material, such as calcium hypochlorite, is described. The apparatus includes in combination: a container, a lid removably mounted on the upper end of the container, and a housing. In operation, the lid is mounted on the container, which contains solid chemical material, and both are inverted and placed on top of the housing. A nozzle within the housing extends through a hole in the lid into the internal space of the container such that dissolving fluid is charged into the container through the nozzle where it contacts the solid chemical material. A solution of chemical material is formed within the container and the solution drains through additional holes formed in the lid and is removed from the housing to a point of use.
