The part needs to be rotated by 90 degrees plus the rotational angle α of the rear plate part 32. The movement of the front plate portion 31 and the rear plate portion 32 is related to the relationship that the front plate portion 31 rotates in the opposite direction around the thin portion as the rear plate portion 32 rotates so that the thin portion side can be moved downward. Become. FIG. 1 shows a model to explain the mechanism of the present invention. When the rear plate portion 32 is rotated about the rotation shaft 34, the thin portion 36 of the lid 3 is always on the circumference of the radius R1 with the rotation shaft 34 provided on the cap body 2 as the center. Here, R1 is the distance between the rotating shaft 34 and the thin portion 36. Under such a relationship, when the lid 3 is in the closed state (I), the front plate portion 31 and the rear plate portion 32 are on the position plane as depicted by the solid line. When in the fully open state (III), the front plate portion 31 has an opening angle of 90 degrees with respect to the top portion 20 with the outlet hole 21 and the rear plate portion 32 has an angle α as depicted by the alternate long and short dash line. I want to. The state of (II) when the lid 3 is in the middle position is shown by a broken line.

Therefore, in the present invention, the front plate portion 31 is also provided with a rotation shaft 37 at a position away from the thin portion 36 by a predetermined distance R2, so that the position of the rotation shaft 37 when the lid body 3 is in the closed state and the fully open state. A long hole 27 extending in the front-rear direction connecting a certain position of the rotating shaft 37 at a certain time is provided in the cap main body 2 to guide the rotating shaft 37. By this mechanism, when the rear plate portion 32 of the lid 3 is pressed and rotated counterclockwise on the drawing, the thin portion 36 is moved rearward and downward on the circumference, and the thin portion 36 has the front plate Since the portion 31 is connected, the front plate portion 31 is also pulled in that direction. However, the front plate portion 31 is provided with a rotation shaft 37 at a position separated from the thin portion 36 by a predetermined distance R2, and the rotation shaft 37 is guided by a long hole 27 provided in the cap body 2. The front plate portion 31 is rotated clockwise by the hinge action of the thin wall portion 36 while allowing the displacement in the direction to be fully opened. In the closing operation, if the end of the rear plate 32 of the lid 3 tilted by the α angle is pressed, the rear plate 32 rotates clockwise in the drawing, and the thin portion 36 moves forward on the circumference. Since the front plate portion 31 is connected to the thin portion 36, the front plate portion 31 is also pushed up in that direction. However, the front plate portion 31 is provided with a rotation shaft 37 at a position separated from the thin portion 36 by a predetermined distance R2, and the rotation shaft 37 is guided by a long hole 27 provided in the cap body 2. The front plate portion 31 is rotated counterclockwise by the hinge action of the thin portion 36 while allowing the displacement in the direction to be displaced to the closed state. Thus, the mechanism of the present invention is a mechanism that can easily open and close the lid by a one-touch operation of pressing and rotating the rear plate portion 32. Further, although it is made of a two-piece plastic member, the fully open state of the lid 3 is to secure an opening angle of 90 degrees with respect to the top portion where the swing hole 21 is located. Will not be an obstacle to withdrawal.
