PROBLEM TO BE SOLVED: To suppress sticking of a dispenser head that happens when the dispenser head is removed from the mouthpiece of a barrel. SOLUTION: Three claw 2a, 2b, and 2c are provided at a recess in an lower surface of a dispenser head 1 connected separably to a mouthpiece including a spear valve. Slopes 21a, 21b, and 21c for guiding in a tongue portion of a flange are formed on the upper surfaces of the claws 2a, 2b, and 2c, respectively. Among these three claws 2a, 2b, and 2c, one or two nails are given a slope of a longer distance than the rest of the claws. As a result, when the dispensing head is removed from the mouthpiece, the presence of a slope of a longer distance allows the whole of the head to tilt to release residual inner pressure from a barrel.
