Abstract

Improvements in osmotic distributors of active agents, characterized in that they comprise a first compartment with controlled permeability to water and containing an osmotically effective solute, which, in solution, shows an osmotic pressure gradient against water, and a bag compartment flexible of relatively waterproof material containing an active agent provided with means for releasing said active agent to the outside of the dispenser, said first compartment and the flexible bag compartment being of a single construction, both compartments being physically arranged relative to each other, in such a way that the bag responds in a folding way to an increase in the volume of the compartment by absorption of water in it, so that as the water emigrates into the distributor by osmosis with a tendency to seek osmotic balance with its environment and exerting a disinfl force On the flexible bag, active agent is continuously squeezed from it at an osmotically controlled rate over an extended period of time.
