Abstract:
A substance delivery system comprising:a) a film material having a gauge of from about 0.0001 inches to about 0.010 inches deformed into a three dimensional structure having outermost surface features and spaces between said outermost surface features for containing a substance, said substance having a level internal to said outermost surface features such that said substance is protected from inadvertent contact with external surfaces, wherein said three dimensional structure has a number density of said outermost surface features greater than 200 outermost surface features per square inch; b) a substance having substantial resistance to flow prior to delivery to a target surface occupying said spaces of said three dimensional structure, said substance remaining protected until said three dimensional structure is sufficiently deformed into a substantially two dimensional structure and said substance is thereby exposed to contact an external surface without compliance of said external surface being necessary.
