ABSTRACT:
A system is disclosed for dispensing an useful agent. The system comprises (1) means for storing an agent, (2) an agent stored in the means, (3) means for releasing agent from the system, (4) means for absorbing fluid into the system surrounding the storing means, and (5) means for admitting fluid into the system. In operation fluid is admitted into the system by the admitting means cooperating with the absorbing means, causing it to increase in dimensions and apply force against the storing means, which force urges the storing means to decrease its dimensions and correspondingly dispense agent through the releasing means from the system. Laminates are disclosed useful for manufacturing the system.
