Title:
物質を目標面に送達するための多段階漸次性(multi‐stageprogressive)活性を有する選択的に活性化可能な三次元シート材料
Document Type and Number:
Japanese Patent JP4361209
Kind Code:
B2
Abstract:
The present invention provides a selectively-activatible sheet material for delivering a substance to a target surface. The sheet material comprises a three-dimensional sheet of material having a first side and a second side. The first side has a plurality of hollow protrusions extending outwardly therefrom and separated from one another by valleys, while the second side has a plurality of depressions corresponding with the hollow protrusions. A substance adheres to and partially fills a location protected from external contact comprising the valleys and/or depressions. The sheet material may be selectively activated by deforming the hollow protrusions to deliver the substance to a target surface. The three-dimensional structure includes hollow protrusions which are adapted to progressively activate in multiple discrete stages to effect multistage progressive delivery of the substance to the target surface. The present invention also provides selectively-activatible sheet materials which incorporate a three-dimensional structure adapted to progressively activate in response to increasing compressive force levels via tailoring of the geometrical shapes of respective hollow protrusions. The present invention also provides selectively-activatible sheet materials which incorporate a three-dimensional structure adapted to progressively activate in response to increasing levels of deformation via tailoring of the geometrical shapes of respective hollow protrusions.
