  • Patent number: 5346061
    Abstract: A treatment delivery system which uses a flexible plastic outer container and a smaller, readily burstable, thin film plastic inner container fixedly positioned in the outer container. The inner container contains a treatment solution and a dry foam appliance is loosely placed within the inner container. When the inner container is burst by applying pressure to the outer container at a position which corresponds to the position of the inner container therein, the treatment solution comes into contact with the foam appliance so as to be absorbed by, and to wet the appliance. The wetted foam appliance can then be removed from the outer container for use.
