At this point, since the slide protrusion 54 of the pull-up wall 53 of the opening portion 50 is not engaged with the guide protrusion 67 of the rail member Ea, the resistance when opening the upper lid D can be reduced.

Further, when the knob 37 is lifted, as shown in FIG. 10B, the opening wall 53 of the opening wall 53 is formed by engaging the slide protrusion 54 with the guide protrusion 67 of the rail member Ea. It is pulled up with the lifting of the knob 37, and the weakened portion 51 starts to break from the vicinity of the injection side of the pulling wall 53.
After that, as shown in FIG. 11A, as the upper lid D is lifted, the sliding protrusion 54 of the pulling wall 53 of the opening portion 50 is rearward (hinge C) along the guide protrusion 67 of the rail member Ea. Sliding to the side) and abutting the closing wall 69, the pulling wall 53 is held between the guide protrusion 67 and the upper wall 70 by a rib 71 having a slide protrusion 54 provided on the upper wall 70. To.
As a result, the pulling wall 53 of the opening portion 50 is pulled up, and the weakening portion 51 breaks to the hinge C side end.

Further, when the upper lid D is lifted, as shown in FIG. 11B, the opening portion 50 completes the breakage of the weakened portion 51, and the opening portion 50 has the slide protrusion 54 of the pulling wall 53 railed. Since it is held by the member Ea, the opening is completed by shifting to the upper lid D.
If the container A is tilted in this state, the content liquid in the container A is guided to the inner peripheral surface of the pouring cylinder 6 from the pouring outlet opened in the partition wall 55 and poured out.

As described above, in the hinge cap of the present embodiment, when the upper lid D is started to be lifted at the time of opening, the upper lid D and the cap body Ba are first disengaged, and then the guide protrusion 67 of the rail member Ea is released. Engages with the slide protrusion 54 of the opening portion 50, pulls up the pulling wall 53, starts breaking the weakened portion 51 from the ejection side of the opening portion 50, and then continues to lift the upper lid D. Then, the breaking of the weakened portion 51 is advanced to the end portion on the hinge C side, and finally, the opening portion 50 is held by the rail member Ea to shift to the upper lid D.

In the hinge cap of the present invention, the upper lid D is closed again to the cap body Ba after using the content liquid, so that the upper lid D dispenses the sealing cylinder 33 and the cap body Ba while holding the opening portion 50. A seal portion is formed with the cylinder 6, the inside of the container A can be sealed again, and the upper lid D of the hinge cap can be repeatedly opened and closed for use.

In the hinge cap of the present invention, when the upper lid is lifted, the cap body and the upper lid are first disengaged, and then the side opposite to the hinge of the weakened portion is pulled up, so that an extra force is required to break the weakened portion. The opening part can be easily opened, and the planned opening part has an opening part that is connected by a weakened part, so it has excellent sealing performance and is for a container that stores the content liquid that requires airtightness. It can be applied to a wide range as a hinge cap.
