PROBLEM TO BE SOLVED: To minimize a quantity of a paste remaining in a flexible paste tube at the end of its use by making the squeeze-out of the paste in the tube easy by a simple structure. SOLUTION: A squeeze-out accelerator 20 for squeezing the paste P out of the tube 10 is incorporated at the tail end in the tube. The accelerator forms the foundation of the paste in the tube, has a cylindrical barrel which tightly fits into the internal surface of a tube wall in a slidable manner, and has a protrusion 22 of a shape aligning with the interior of a tube squeeze-out nozzle 12. When in use, the squeeze-out accelerator is advanced toward the nozzle, thereby squeezing the paste through the nozzle. The protrusion is of a shape to fit with a squeeze-out nozzle hole. The top face of the accelerator is in contact from the inside with a shoulder of the tube adjacent to the nozzle. COPYRIGHT: (C)2005,JPO&NCIPI
