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.
Claims9
A treatment delivery system comprising a readily openable hermetically and completely sealed flexible plastic outer container forming a single first chamber;
- a completely sealed and flexible plastic inner container, forming a single second chamber, which is smaller than said outer container and is fixedly positioned within the single first chamber of said outer container so as to be completely enclosed therein, said inner container containing a treatment solution and being made of a thin film plastic material so that it can be readily burst upon the application of pressure thereto;
- a dry foam element placed within said outer container;
- means on said outer container for indicating the position of said inner container within said outer container so that, when pressure is applied to the outer container at said indicated position, the inner container bursts and said treatment solution comes into contact with said dry foam element so as to wet said foam element with the treatment solution, whereby the wetted foam element is available for delivery of said treatment solution when the outer container is open.
