It comprises a flange 27 and a fitting cylinder 29 that hangs down from the lower surface of the flange 27 and fits into the inner peripheral surface of the mouth portion 5. In the present embodiment, the central axis (hereinafter simply referred to as “axis”) C of the spout 25 coincides with the central axes of the pour pipe 26, the mouth 5, and the trunk 15.

  The container body 3 has a pair of engaging projections 31 protruding from the side surfaces on both sides of the body portion 15. As shown in FIG. 1, the pair of engaging convex portions 31 are arranged on an axis D perpendicular to the axis C, and enter the engaging hole 33 of the oscillating body 11 so that the oscillating body 11 is oscillated. It becomes a fulcrum when moving. Further, the upper surface of the side surface of the body portion 15 provided with the engaging convex portion 31 is recessed inward from the lower portion so that the connecting portion 35 of the rocking body 11 is accommodated.

  The oscillating body 11 includes a pair of connecting portions 35 that fit into the container body 3 and a ceiling wall 41 that has a circular opening 39 in the center and bridges the connecting portions. In the non-use state shown in FIG. 1, the top wall 41 is located above the flange 27 of the inner plug 7 disposed at the upper end of the mouth portion 5, and the dispensing tube 26 penetrates the opening 39 of the top wall 41. ing.
