There was a risk of cutting the thin-walled weakened portion 13.
By the way, even with the conventional hinge cap, even if the sealing ring 32 other than the vicinity of the longest tip portion 32b is pushed in, the partition wall is separated from the partition wall 5 by the tip portion of the sealing ring 32, so that the partition wall precedes the longest tip portion 32b. There is no risk of contact with 5.

In the hinge cap of the present embodiment, first, a plurality of reinforcing ribs 36 are provided on the inner circumference of the side peripheral wall 31 of the upper lid B at predetermined intervals in the vertical direction so as to reach the annular recess 35 from the top wall 30. Deformation of the side peripheral wall 31 of the upper lid B is suppressed, and further, the lower surface 36a of the reinforcing rib 36 is in contact with the upper surface of the lid engaging portion 9 of the cap body A, and the side peripheral wall 31 is suppressed from being pushed and deformed. There is.

Further, even if the sealing ring 32 is pushed toward the container body D side and the longest tip portion 32b abuts on the lowest upper surface 5a of the partition wall 5, as shown in FIG. 4B, the inner peripheral side of the longest tip portion 32b Prevents the longest tip portion 32b from moving to the thin-walled weakened portion 13 side by abutting on the outer peripheral side of the stopper rib 22.
Further, the stopper rib 22 exerts a force that causes the longest tip 32b to shift outward (seal wall 19 side) with respect to the contact of the longest tip 32b due to the gradient of the lowest upper surface 5a of the partition wall 5, and the longest tip 32b. There is no risk of getting over the stopper rib 22.

As described above, the hinge cap of the present embodiment falls on the inner circumference of the side peripheral wall 31 of the upper lid B even when the container is dropped in an inverted state and the upper lid B is landed underneath before the container is opened. The reinforcing rib 36 provided and the stopper rib 22 provided on the partition wall 5 of the cap body A deform the upper lid B, push the longest tip portion 32b of the sealing ring 32, and break the thin-walled weakened portion 13 of the partition wall 5. The hermeticity inside the container body D can be maintained without causing the container body D to be sealed.

When using the content liquid in the container body D, the grip portion 34 of the upper lid B is pulled up, the upper lid B is opened from the cap body A, and then the pull ring 16 is connected to the removal portion 14 defined on the partition wall 5. Is pulled upward, the removing portion 14 is pulled up via the support column 15, the thinning weakening portion 13 is broken, the removing portion 14 is separated from the partition wall 5, and the plug is removed, and the spout S is opened.

If the content liquid contained in the container body D is a dressing, oil, or the like that shakes and stirs the container body D before use, the removing portion 14 is separated from the partition wall 5 to open the spout S, and then once. After closing the upper lid B and shaking the container body D, the upper lid B is opened again, the container body D is tilted, and the content liquid is guided by the inner surface of the pouring cylinder 12 of the cap body A and dispensed.

The content liquid agitated when the container body D is shaken flows out from the spout S and adheres to the inside of the sealing ring 32 on the inner surface of the top wall 30 of the upper lid B, but the adhered liquid collects a plurality of liquids. Guided by the ribs 33, they flow down to the hinge C side, respectively, and are collected on the inner peripheral surface of the longest tip portion 32b on the hinge C side due to the inclination of the tip portion of the sealing ring 32. Therefore, the amount of liquid adhering to the inner surface of the top wall 30 can be reduced.

Further, when the lid is opened again for using the container, the upper lid B is rotated about the hinge C, but the dripping prevention flap 37 on the longest tip portion 32b side of the sealing ring 32 is the sealing ring 32. It temporarily catches the liquid adhering to the inner circumference of the closure and acts to prevent dripping.

When the inclination of the container is restored at the time of pouring or after pouring, the content liquid may leak to the outside along the outer peripheral surface of the pouring cylinder 12.
At that time, as shown by the arrow shown in FIG. 3, the liquid leaking to the outside of the pouring cylinder 12 flows down to the liquid recovery path 20, but the bottom of the liquid recovery path 20 is hinged from the side opposite to the hinge C. Since a downward slope is provided toward the C side, when the inclination of the container is restored, the container flows down toward the hinge C side.

The liquid that has flowed down the inclined surface of the liquid recovery path 20 is collected on the lowest surface 21 formed on the hinge C side of the liquid recovery path 20, and is sealed from the shoulder portion 18 between the end portions 17 and 17 of the pouring cylinder 12. It returns to the inside of the container body D from the spout S through the wall 19.
Even as described above, if the liquid remains in the liquid recovery path 20, even if the container body D is tilted, the liquid is provided in the liquid dripping prevention fin 23 provided on the opposite side of the hinge C of the liquid recovery path 20. Temporarily stays to prevent dripping and does not stain the area around the hinge cap.

Further, the hinge cap of this embodiment can be separated from the container body D and separately disposed of after using the content liquid in the container body D.
First, when the upper lid B is opened and pulled upward, the weakened piece 25 connecting the outer cylinder 8 of the cap body A and the outer cylinder portion 11 is broken, and the hinge C side of the outer cylinder portion 11 is pulled away from the outer cylinder 8. Further, when the upper lid B is continuously pulled, the outer cylinder 8 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 indestructible connecting piece 24.

The hinge cap of the present invention reduces the adhesion of the content liquid in the hinge cap, does not stain the area around the hinge cap, and can maintain the sealing property inside the container even if the container is inverted and dropped before use. Therefore, it can be widely used as a hinge cap for a container that requires a hygienic usage environment, and is particularly suitable as a hinge cap for a container filled with liquid foods such as cooking oil and liquid seasonings.
