A DELIVERY SYSTEM FOR AN ORAL CARE SUBSTANCE USING A STRIP OF MATERIAL HAVING LOW FLEXURAL STIFFNESS

摘要

A delivery system for an oral care substance is new:The system comprises: (a) a strip of material sufficiently flexible to form a curved shape on an oral surface (preferably having a constant flexural stiffness of less than 5g/cm as measured by ASTM test method D2923-95) and which is water impermeable (most preferably polyethylene); and (b) an oral care substance, preferably a gel, applied as a uniform continuous coating on the strip. The substance acts as an adhesive between the strip and the surface to hold the system in place for sufficient time for the substance to act on the surface. The strip is capable of recovery from its deformed state in the absence of the adhesive force due to the substance.
