PURPOSE:To reduce the amount of a content which remains in a neck part by a method wherein a cap is integrally connected to the neck part by a hinge, and the internal diameter of the neck part is substantially made smaller. CONSTITUTION:A neck part 12 to which a cap 14 is integrally attached by a hinge part 13 is attached to an upper part of an tube main body of a tube 10. For such a tube 10, on the whole surface of the inner peripheral wall surface of the neck part 12, a large number of wide vertical protruding ribs 17 and narrow vertical protruding ribs 18 are alternately provided in the radial directions in such a manner that gaps between them may become smaller for the constitution of the neck part 12. |
