To achieve deterrence of sagging of the residual contents in the peripheral portion and the contents of the outlet, such as solidification and outer draw. Depressing the operation button 2 of the stationary mode, passage member 5 is moved to the left on the drawing by the action of the tapered surface 2c, discharge port 5a of the contents to communicate with the external space away from the seal member 4. Instead of plugging directly with the seal member 4 the outlet 5a, and abut the sealing action face 4a flange portion 5c of the passage member disposed in the external space side of the outlet, and 24c in the quiescent mode . Also, when returning to the contact state, the periphery of the outlet 5a (residual content easily adhere) to the large-diameter outer circumferential portion 5b, the large diameter inner peripheral surface 4b of 4 (the seal member portion which is opposed thereto ) is prevented from contacting. Back suction space range is set between the skirt-like portion 6b of the breech portion 6 and the rear end portion of the sealing member 4.
