Therefore, the relationship is formed (outer diameter of the elastic flange portion 23b)>(inner diameter of the protruding portion 6)>(outer diameter of the elastic sleeve portion 23c).

When the lid body 7 is installed on the container body 2 , the waterproof gasket 23 abuts against the protruding portion 6 of the container body 2 , thereby elastically deforming and coming into close contact with the protruding portion 6 over the entire circumference. Specifically, the lower surface of the elastic flange portion 23 b is in surface contact with the entrance side of the protrusion 6 , and the outer peripheral surface of the elastic sleeve portion 23 c is in surface contact with the top side of the protrusion 6 .

At this time, the waterproof gasket 23 elastically deforms along the inlet side surface of the protruding portion 6 through the elastic flange portion 23 b, so that the elastic sleeve portion 23 c faces the outer peripheral surface of the elastic sleeve portion 23 c and the protruding portion 6 . The elastic displacement in the direction of surface contact on the top side causes the elastic flange portion 23b to be lifted upward along the inlet side surface of the protruding portion 6. With this, the elastic sleeve portion 23c expands in the diameter expansion direction, forming a In a state of being pressed against the top surface of the protruding portion 6 . Thereby, the waterproof gasket 23 can be brought into close contact with the protruding portion 6 and the sealing property between the protruding portion 6 (container body 2) and the spout forming member 12 (lid body 7) can be well maintained.

In addition, the waterproof gasket 23 is not necessarily limited to the elastic sleeve portion 23c having a tapered shape that gradually expands downward in diameter. The shape of the elastic sleeve portion 23c can be determined by the elastic flange portion 23b along the convex shape. The surface on the inlet side of the outlet portion 6 can be elastically deformed so that the elastic sleeve portion 23c can be elastically displaced in a direction in contact with the surface on the top side of the protruding portion 6 .
