To easily obtain a tubular vessel of excellent oxygen barrier property and excellent content extrusile property at a low cost without requiring a large volume of packaging materials or a large number of complicated manufacturing steps.

A barrel 11 of the tubular vessel 10 is formed of an aluminum- laminated resin, a cap 5 which is formed of a substantially oxygen-impermeable material is fitted thereon. A shoulder 12 and a nozzle 13 are covered by the cap 15. When an inner top side 16 of the cap 15 is abutted on a tip 17 of the nozzle 13, a circumferential edge 18 of the cap 15 is tightly attached to the barrel 11. An annular projection 20 extending circumferentially along the circumferential edge 18 is provided on the circumferential edge 18 of the cap, and the circumferential edge 18 is tightly attached to the barrel 11 so that the annular projection 20 bites an upper end 19 of the barrel 11.
