<P>PROBLEM TO BE SOLVED: To provide a dosage-dispensing unit for highly-accurately dispensing a substance of a dosage which is measured by reliably closing an outlet hole all the time. <P>SOLUTION: The dosage-dispensing unit 100 for a dosage material of a powdery or granular consistency includes a housing 101, at least one reservoir cavity 102 formed inside the housing 101 to serve for receiving the dosage material, and at least one dispensing head 104 containing an elastomeric material. The dispensing head 104 has an outlet 107 which is slit-shaped in the non-deformed state, is delimited by a first outlet lip 108 and a second outlet lip 109, and is opened to a variable width by laterally applying a compressive force. The configuration further includes at least a first motion transmitting means designed to give the first outlet lip 108 an oscillatory movement in the lengthwise direction of the second outlet lip 109 relative to the second outlet lip 109. <P>COPYRIGHT: (C)2012,JPO&INPIT |
