Further, inside the skirt portion 26, vertical ribs 27 are formed at equal intervals in the circumferential direction over the vertical direction.

Next, usage modes and operational effects of this embodiment will be described.
The hinge cap of the present embodiment is attached by being plugged into the mouth 1 of the container body D in the closed state shown in FIG.
In the plugging process, the mouth 1 of the container body D is applied to the annular groove formed between the inner cylinder 5 and the outer cylinder 7, and a pressing force is applied from above the upper lid B so that the outer cylinder 7 is fitted. The protrusion 18 gets over the engagement protrusion 2 of the mouth 1 and fits into the constricted recess 3, and the mouth 1 is sandwiched between the outer periphery of the inner cylinder 5, the inner periphery of the outer cylinder 7, and the base wall 6. Installed.

In order to use the container equipped with the cap of this embodiment, as shown in FIG. 2B, the upper lid B is opened, the pull ring 14 is pulled upward, and the removal portion 12 of the partition wall 4 is pulled up via the support column 13. Then, the thinned portion 11 is cut, the removal portion 12 is cut off from the partition wall 4 and the stopper is opened, and the spout S is opened as shown in FIG.
Since a thin plate-like buffering portion 15 is provided on the lower side of the pull ring 14 opposite to the hinge C, the buffering portion 15 can be easily bent when a finger hits it, and the contact pressure on the finger can be softened. .

When the content liquid is poured out by tilting the container, the liquid flowing out from the spout S is guided to the inner peripheral surface of the pour cylinder 10 and is poured out from the trumpet-shaped tip 10a.
As shown in FIG. 1, after the use of the container is finished, when the upper lid B is closed, the reduced diameter protrusion 24 of the side peripheral wall 22 gets over the bulging portion 16 of the lid locking portion 8 of the cap body A, and the engagement recess. 17 to return to the closed state.

At this time, the annular tightening portion 25a formed on the outer periphery of the inner ring 25 forms a seal portion that is in contact with the inner peripheral surface 10b of the dispensing cylinder 10 and is continuous in the circumferential direction, and the upper lid B is formed by the seal portion. The interior is partitioned into a space a communicating with the spout S and a space b sealed from the spout S.
Therefore, even if the container falls or tilts and the content liquid flows out from the spout S, the liquid does not leak into the space b, and the adhesion of the liquid is limited to the space a.
However, the content liquid adheres to the inner peripheral surface and the tip of the inner ring 25.

When the lid is opened to use the container again, as shown in FIG. 1, when the knob 23 of the upper lid B is lifted with a finger, an annular shape that engages with the engaging recess 17 of the lid locking portion 8 is used. When the reduced diameter protrusion 24 is deformed, the locking of the lid locking portion 8 with the engagement recess 17 is released, and the upper lid B is rotated around the hinge C.
When the locking of the upper lid B with the cap main body A is released, the ring-shaped reduced diameter protrusion 24 is slightly deformed, so that the upper lid B is vibrated.
At the same time, as shown in FIG. 4B, the tightening portion 25a on the outer periphery of the inner ring 25 is also released from contact with the inner surface of the extraction tube 10, and the inner ring 25 also vibrates.
However, in the present invention, the upper cover B is opened as shown in FIGS. 4 (a) and 4 (b) by forming the skirt portion 26 extending from the tip only on the outlet side of the inner ring 25. When the contact between the inner ring 25 and the dispensing cylinder 10 is gradually released, the vibration of the inner ring 25 itself is attenuated, and the liquid adhering to the skirt portion 26 is prevented from scattering. .

Further, the side peripheral wall 22 can be opened with a light force when releasing the locking of the upper lid B and the cap body A by virtue of the thin-walled portion 22a in the vicinity where the knob portion 23 is formed. Can be suppressed.
Therefore, it is possible to further prevent the content liquid from being scattered due to a synergistic effect with the skirt portion 26.
Further, since the vertical rib 27 is formed on the inner side of the skirt portion 26 in the vertical direction, even if the content liquid adheres to the inner ring or the tip of the inner ring 25 when the lid is closed, the vertical rib 27 As shown in FIG. 2, the liquid is held and does not sag and scatter when it is opened.
Further, since the vertical ribs 27 are formed on the skirt portion 26, even if the skirt portion 26 is formed thinner than the inner ring 25, the strength reduction can be suppressed.

On the other hand, on the hinge C side of the inner ring 25, there is no possibility of scattering unlike the pouring side even if the liquid is attached, so it is not necessary to form the skirt portion 26.
Then, as shown in FIG. 4 (b), even when the upper lid B is opened and the inner ring 25 opens the dispensing cylinder 10, the skirt portion 26 still remains inside the dispensing cylinder 10. Therefore, an excellent effect is obtained that the liquid adhering to the tip of the skirt portion 26 is not scattered.

Further, the hinge cap of this embodiment can be separated from the container body D and discarded after the container is used.
When the upper lid B is opened and pulled outward, the weakening piece 20 that connects the outer cylinder 7 and the outer cylinder part 9 of the cap body A is broken, and the hinge C side of the outer cylinder part 9 is pulled away from the outer cylinder 7, When the upper lid B is further pulled upward, the outer cylinder 7 can be easily removed from the mouth portion 1 of the container body D so as to be turned up from the portion connected to the connecting piece 19.

  Since the hinge cap of the present invention reduces the scattering of the liquid adhering to the inner ring suspended from the back surface of the top cover when the top cover is opened, and does not contaminate the back surface of the top cover or the periphery of the cap body. It can be widely used as a cap for a liquid dispensing container that requires a particular use environment, and is particularly suitable as a cap for a container filled with liquid food such as edible oil or liquid seasoning.
