Document Type and Number:

WIPO Patent Application WO/2017/069082

Kind Code:

Abstract:

The present invention relates to a cartridge for a viscous material dispenser. A seal (104) is disposed between a plunger (10) and a cylinder (18), said seal (104) being configured so as to include: a plurality of spacers (400) that occupy, in the circumferential direction, a portion of an annular space between the plunger (10) and the cylinder (18); and a plurality of axial-direction continuous clearances (106) that are formed in an area excluding the area where the plurality of spacers (400) are disposed, and that, in a cartridge (12), extend in a direction including at least the axial direction component of said cartridge, thereby allowing a filling chamber (72) and a pressurization chamber (74) to communicate with each other. When viscous material is filled into the filling chamber (72) from the outside, the viscous material is also filled into the plurality of axial-direction continuous clearances (106), and as a result of the combination of the plurality of axial-direction continuous clearances (106) into which the viscous material has been filled and the plurality of spacers (400), the seal (104) is formed.
