And the region including the region where the slit 46 is formed on the shielding wall 44 in more detail. As a result, even when the inner pressure of the container is raised when the intermediate lid 6 is positioned in the closed position together with the outer lid 8, the shielding wall 44 is deformed in a projecting shape and the slit 46 is expanded to reduce the amount of the small amount. A discharge opening is created and the contents are prevented from being discharged from this small discharge opening. In the state where the outer lid 8 is positioned at the closed position with respect to the intermediate lid 6, the inner circumferential surface of the seal piece 64 formed on the top wall 52 is further brought into close contact with the outer circumferential surface of the upper portion 40 c of the protruding cylinder 40. (If desired, the seal piece 64 may be positioned so that the outer peripheral surface of the seal piece 64 is brought into close contact with the inner peripheral surface of the upper portion 40c of the protruding cylinder 40). Thereby, discharge of the contents from the above-described small amount discharge opening is more reliably prevented.

  The hinge means 50 for pivotally connecting the intermediate lid 6 to the lid body 4 and the hinge means 56 for pivotally connecting the outer lid 8 to the intermediate lid 6 are arranged at an angular interval of 60 to 150 degrees. Conveniently installed. In the illustrated embodiment, as clearly understood by referring to FIGS. 2 and 3, the hinge means 50 pivotably connects the intermediate lid 6 to the lid body 4 and the outer lid 8 to the intermediate lid 6. Are disposed at an angular interval of 90 degrees.

  FIGS. 1 and 4 to 7 also show the container neck 2 of the container to which the container lid 2 is applied together with the container lid 2 configured according to the present invention. A container that can be formed from an appropriate synthetic resin such as polyethylene terephthalate has a cylindrical mouth / neck portion 66 as a whole, and an annular locking protrusion 68 is formed at the upper end of the outer peripheral surface of the mouth / neck portion 66. Has been. A support ring 70 positioned below the locked protrusion 68 is also formed on the outer peripheral surface of the mouth and neck portion 66.

  For example, when the container lid 2 is attached to the mouth / neck portion 66 after the contents of liquid seasoning are filled in the container and the mouth / neck portion 66 is sealed, the intermediate lid 6 and the outer lid 8 are both closed. The container lid 2 positioned on the mouth and neck portion 66 is fitted, and then the container lid 2 is forced downward with respect to the mouth and neck portion 66. Thus, as clearly shown in FIGS. 4 and 5, the sealing piece 24 of the lid main body 4 is brought into close contact with the inner peripheral surface of the container, and the locking protrusion formed on the inner peripheral surface of the side wall 12 of the lid main body 4. The strip 26 elastically climbs over the locked protrusion 68 formed on the outer peripheral surface of the mouth-and-neck portion 66 so as to be locked below it.

When the contents contained in the container are consumed, first, the intermediate lid 6 together with the outer lid 8 positioned in the closed position is viewed from the closed position illustrated in FIGS. 1, 4, and 5. 7 is swung to the open position illustrated in FIG. 7 to expose the closed wall 10 of the lid body 4. Then, the pulling means 22 is put on a finger and pulled upward to break the breakable line 20 to remove the removal region 18 from the blocking wall 10 to create a relatively large mass discharge opening in the blocking wall 10. The intermediate lid 6 is returned to the closed position together with the outer lid 8.
When discharging a small amount of the contents stored in the container, the outer lid 8 is swung from the closed position shown in FIGS. 1, 4 and 5 to the open position shown in FIG. The shielding wall 44 in which the opening is formed is exposed, and then the container is turned upside down to compress the body of the container. As a result, the internal pressure of the container is raised, the shielding wall 44 is deformed upward as shown by a two-dot chain line in FIG. 6, and the cross-shaped slit 46 is expanded as shown by a two-dot chain line in FIGS. Then, a small amount discharge opening is formed, and a small amount of contents are discharged from the small amount discharge opening. After discharging the desired amount of contents, the compression of the body of the container is released and the internal pressure of the container is returned to the atmospheric pressure, so that the shielding wall 44 returns to the original concave shape and the extension of the slit 46 is released so that the slit 46 is released. Closed. This stops a small amount of the contents from being discharged and prevents dripping. When the outer lid 8 is returned to the closed position, the sealing portion 62 of the outer lid 8 is brought into close contact with the upper surface of the shielding wall 44, and thus the slit 46 in which the small amount discharge opening is formed is sufficiently securely sealed.
When discharging a large amount of contents contained in the container, the intermediate lid 6 is illustrated in FIG. 7 from the closed position illustrated in FIGS. 1, 4 and 5 together with the outer lid 8 positioned in the closed position. Rotate to the open position to expose the closing wall 10 of the lid body 4. Next, when the container is tilted, the contents can be discharged in large quantities through the large discharge opening. When a large amount of content is discharged through the generated large discharge opening, the content is discharged sufficiently smoothly by the guide action of the discharge guide tube 16. After the mass discharge is completed, the intermediate lid 6 is turned to the closed position together with the outer lid 8. In this way, the outer peripheral surface of the seal cylinder 34 of the intermediate lid 6 is brought into close contact with the inner peripheral surface of the discharge guide cylinder 16 of the lid body 4, thereby sufficiently reliably sealing the large volume discharge opening via the discharge guide cylinder 16. .

  In the illustrated embodiment, a breakable line 20 that defines the removal region 18 is formed radially inward of the closing wall 10 of the lid body 4 with respect to the discharge guide tube 16, and the tension means 22 is provided on the upper surface of the removal region 18. The removal area 18 is formed by forming and pulling the pulling means 22 so as to form a large discharge opening, but instead of this, the discharge guide cylinder 16 in the closing wall 10 of the lid body 4 is more suitable. A large-volume discharge opening having a required shape can be formed in advance in the radial direction. Further, the small amount discharge member 42 in the illustrated embodiment is formed with a slit 46 that is expanded when the internal pressure of the container is increased to generate a small amount discharge opening. For example, a small amount discharge member having a valve plate disclosed in Japanese Patent No. 4043682 may be employed.
