Patent ID: 7279064

Claim:
A method of enclosing a plurality of microstructural chambers containing a substance, said method comprising steps of: a) providing a first substrate and a second substrate, said first substrate having a wall microstructure with an exposed end portion and forming said plurality of microstructural chambers; b) applying and affixing a plurality of microcapsules along one of a first side of said second substrate and said end portion of said wall microstructure, said microcapsules containing one of an adhesive substance and a first component of a multi-part adhesive substance; c) covering at least a portion of said plurality of affixed microcapsules with a first coating operative to modify an interaction between the substance, said plurality of microcapsules and a corresponding one of said first and second substrates upon which said plurality of microcapsules are affixed; d) positioning said first side of said second substrate adjacent said end portion of said wall microstructure; and, e) urging said second substrate toward said end portion of said wall microstructure with a force of sufficient magnitude to rupture said first coating and at least a portion of said plurality of microcapsules such that said adhesive substance is dispensed between said first and second substrates with resulting unruptured portions of said first coating remaining within said plurality of microstructural chambers for modifying said interaction between the substance, said plurality of microcapsules and said corresponding one of said first and second substrates.
