Abstract
A dispenser includes a cartridge moving mechanism and a hopper. The cartridge moving mechanism moves between a cartridge receiving position and an extracting position and between the extracting position and a cartridge exhaust position. The hopper has a dropping unit and is disposed immediately above the cartridge receiving position. The dropping unit serves to drop a cartridge consisting of a fluid-impermeable outer frame and a filters. A space defined between the filters and the outer frame and contains a powdery or granular material to be extracted. An extracting mechanism of the dispenser has an upper extracting head, and a lower extracting head including an extracting tank. The upper extracting head is provided above the extracting position and has an extracting chamber. The extracting tank is provided below the extracting position to face the upper extracting head, and another extracting chamber is formed in the extracting tank. The lower extracting head has a heater for heating the extracting tank and a liquid heating passage communicating with the extracting chamber. The dispenser effectively obtains an extract from the material of the cartridge by dripping.
