To provide a tube container in which an aluminum member is inserted in a head, aluminum foil used in the aluminum member can be made thinner, the opening of a front end upon using the tube container for the first time is facilitated, high virginity before use is achieved, and the insertion of the aluminum member into a form is facilitated.

A tube container is formed in a state that an aluminum member with an unopened front end is inserted in an inner surface of a head comprising a shoulder and a mouth/neck part, and is used after opening the front end of the aluminum member upon unsealing. The aluminum member has a shape of a substantially truncated cone, and an upper surface of the truncated cone is closed.
