To provide a dispensing device in which an inner stopper is attached to a main tube inner peripheral surface via a breaking line and which has a ratchet mechanism between the inner stopper and a cap body, and which has a structure for protecting the breaking line when the cap body is mounted.

The dispensing device for a liquid container includes: a main tube 2 using its end surface as a dispense port 12; an inner stopper 24 connected to an inner peripheral surface of the main tube 2 through the breaking line 22, and having an end 24b protruded outside through the dispense port 12; and a cap body 40 having a base half 42a of a cap peripheral wall threadedly engaged with the dispense tube 8 being the end of the main tube 2 and connects the end half 42b of the cap peripheral wall to the outer periphery of a top wall 44. Between the end half 42b of the cap peripheral wall and the end 24b of the inner stopper, a ratchet mechanism R is formed to inhibit turning of the cap body 40 in an opening direction relative to the inner stopper 24. A plurality of fitting recessed grooves 30 each having a base end side opened and groove-like auxiliary fitting lines 16 each having a base end side open are vertically provided in the inner peripheral surface of the inner stopper 24 and in the inner surface of the main tube part below the breaking line 22, respectively.
