Abstract
A recharge sleeve for use with a spray dispenser device, made of a matrix comprises an absorptive material impregnated with a chemical composition that dissolves in solution created when the sleeve is contacted with a diluent fluid such as water. The recharge sleeve is elongated in shape with a center opening parallel to the long edges of the sleeve for mounting on the diptube of the spray dispenser device. A conically shaped retainer formed of rigid plastic is attached or provided for attachment to the lower end of the diptube for stabilizing the diptube and retaining the recharge sleeve clear of the bottom of the retainer after the sleeve has been applied to the diptube. When of the spray dispenser device is sealed and the spray dispenser device is shaken, the fluid penetrates into the matrix material, and the chemical composition dissolves in the fluid creating a cleaning, sanitizing, or disinfectant solution that will remain stable and fully active in use.
