Abstract
A recharge insert, for use with a spray dispenser device, is made of a matrix material impregnated with a chemical composition that is made dry-to-the-touch and is held in place by a porous three-dimensional polyethylene film that prevents direct skin contact, while allowing the chemical composition to be dissolved in solution with a diluent fluid such as water. When the spray bottle is filled with water, sealed, and shaken, the fluid penetrates into the matrix material, and the chemical composition becomes dissolved in solution, thereby creating a cleaning, sanitizing or disinfectant solution that will remain stable and fully active in use. The recharge insert may be engaged with an insert locating adapter as may be desired.
