PROBLEM TO BE SOLVED: To prevent a defective product generated when a rear end is sealed after filling from being produced by filling viscous liquid from the opened rear end of a thin and flexible cylindrical body of a synthetic resin tube container. SOLUTION: The tube container comprises a rigid shoulder cylindrical frame 2 made of synthetic resin having a filling port 13 whose diameter is larger than that of a filling nozzle 27 for a viscous liquid product, a cylindrical body 11 made of thin, flexible and heat-sealable synthetic resin with the shoulder cylindrical frame 12 attached to a front end and with a rear end sealed, a rigid cylindrical tube head 14 made of synthetic resin having a small diameter squeeze port 15 at the tip and attached to the filling port 13 of the shoulder cylindrical frame 12, and a rigid cap 17 made of synthetic resin for removably closing the squeeze port 15 of the tube head 14. |
