<P>PROBLEM TO BE SOLVED: To provide a dispenser displaying functionality firmly to eject a sticky substance such as a strong glue. <P>SOLUTION: The dispenser (1) to fill a filling part with a sticky material held in a storage (16) is provided with a dispenser housing (21) capable of stretching composed of several housing parts (22, 23) and a nozzle (9), a return spring (32) and a pump chamber (17) capable of decreasing volume. The dispenser housing (21) is given operating power pressurizing the nozzle (9) against the filling part (3)from the backside and the volume of the pump chamber (17) is reduced by relatively reducing and shifting the housing part (22, 23) working in a cover (18) or the storage (16) in the pump chamber, which helps to eject the sticky material (6). The cover (18) in the pump chamber returns to an original position by relatively reducing and shifting the housing part (22, 23) with the return spring (32) placed outside the pump chamber (17), thus enabling the pump chamber (17) to be filled again. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
