Title:
VISCOUS MATERIAL SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2014122586
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a viscous material supply device which improves followability of a seal member of a piston for ruggedness of a tank inner wall and, thereby, prevents viscous material from leaking from a gap.SOLUTION: Viscous material M entered to a synthetic resin film bag B is stored in a tank 2, and an edge part of the opened bag B is folded back and is fastened to an outer circumferential part of the tank 2. The viscous material M is pressed by a piston 3 inserted to the bag B and is extruded from a suction channel 16 disposed on the piston 3. An intermediate part between the tank 2 and the piston 3 is sealed via the bag 2 with a seal member 13 made of synthetic resin foam. An outer diameter of the seal member 13 is made larger than the inner diameter of the tank 2 and the seal member 13 is elastically pressed against an inner wall of the tank 2 via the bag B. Thereby, the followability of the seal member 13 for the inner wall of the tank 2 is improved and, even when wrinkles are formed on the bag B, the viscous material M does not leak from the seal member 13.
