<p num="1"><br/><br/><br/>A one way valve assembly flows a sterile flowable substance from a source to <br/>an outlet orifice and prevents any backflow of contaminants through the one <br/>way valve assembly when the flowable substance ceases to flow. The valve <br/>assembly includes an elastomeric membrane which aids in preventing any <br/>backflow of contaminants when dispensing of the flowable substance is stopped.<br/></p>
