    摘要: A multi-layer one-way valve (100) includes: a first layer (10) having at least one first opening (12) formed therein; a second layer (20) having at least one second opening (22) formed therein; and, a third layer (30). The first and second layers are joined together such that at least one first channel (14) is defined therebetween, and the second and third layers are joined together such that at least one second channel (24) is defined therebetween. Additionally, an amount of flow-able liquid is deposited in the first channel between the first and second openings. Suitably, the valve selectively opens to permit gas flow through the first and second channels in response to a pressure differential, the rate of gas flow through the valve is exponentially proportional to the pressure differential.
