A positioning protrusion 39 is formed on the hinge C side at the lower end of the inner peripheral wall 31.

Next, usage modes and operational effects of this embodiment will be described.
In the hinge cap of the present embodiment, first, the inner plug member D in which the seal S is adhered to the seal surface 29a of the partition wall 29 is assembled to the cap body A with the positioning protrusion 39 on the hinge C side.
At that time, as shown in FIG. 3A, the insertion tube 9 of the cap body A is sandwiched between the inner peripheral wall 31 and the outer peripheral wall 33 of the inner plug member D.
Further, the side peripheral surface and the upper surface of the flange portion 34 of the inner plug member D and the inner peripheral surface upper portion of the outer peripheral wall 33 are the inner peripheral surface of the lid engaging portion 5 of the cap body A, the lower surface of the base wall 4 and the fitting tube 9. The protrusion 38 of the flange portion 34 is fitted to the outer peripheral surface and sandwiched between the inner peripheral engagement concave portion 14 of the lid engaging portion 5 so that the inner plug member D does not fall off from the cap body A. It has become.

Next, the closed hinge cap is plugged into the mouth 1 of the container E filled with the content liquid.
In the plugging step, the mouth portion 1 of the container E is applied to the annular groove formed between the outer peripheral wall 33 of the inner plug member D and the mounting cylinder portion 3 of the cap body A, and the pressing force is applied from above the lid B. Add
At that time, as shown in FIG. 3 (b), the fitting projection 15 of the mounting cylinder 3 rides on the fitting ridge 2 of the mouth 1, and tries to spread the mounting cylinder 3 outward from below. However, since the starting portion 3a of the mounting cylinder 3 is thinner than the thick portion 5a located at the upper portion thereof, the entire mounting portion 6 of the mounting cylinder 3 is deformed starting from the vicinity of the starting portion 3a. When the fitting protrusion 15 gets over the fitting protrusion 2, the deformed container mounting portion 6 is restored to its original state.
Further, the outer peripheral wall 33 of the inner plug member D is inserted while the bulging portion 37 rides on the inner peripheral upper end of the mouth portion 1 and deforms the bulging portion 37 inward to eliminate the space a.

The lid engaging portion 5 of the mounting cylinder portion 3 has the shape retaining property of the lid engaging portion 5 maintained by the contact of the side peripheral surface of the flange portion 34 of the inner plug member D with the inner peripheral surface. It is possible to prevent the lid engaging portion 5 from being pulled inwardly by the deformation of the container mounting portion 6 due to the impact of the stopper and to be deformed inward, and to be fitted to the entire engaged portion 23 of the side peripheral wall 21 of the lid B. Will not be affected.
Moreover, since the container mounting part 6 is formed in a thin wall and easily deforms particularly starting from the vicinity of the starting point part 3a, the pressing force at the time of capping can be reduced as compared with the conventional case.

Finally, as shown in FIG. 4, the upper surface of the mouth portion 1 of the container E comes into contact with the lower surface of the flange portion 34 of the inner plug member D, and the plugging is completed.
When the stopper is finished, the inner periphery of the container mounting portion 6 and the fitting protrusion 15 are brought into close contact with the outer periphery of the mouth portion 1 and the fitting protrusion 2 of the container E by the restoring force of the container mounting portion 6 of the cap body A.
Further, as shown in FIG. 4B, the bulging portion 37 of the outer peripheral wall 33 of the inner plug member D has a restoring force to return to a U-shape and an inner periphery of the insertion tube 9 of the cap body A. Due to the pressure with which the seal projection 16 abuts, the vicinity of the bulging portion 37 of the outer peripheral wall 33 is pressed against the inner periphery of the mouth 1 of the container E, and the adhesion is further improved, and the lower portion of the outer peripheral wall 33 is deformed inward. Can be prevented.

  When using the liquid in the container E, the lid B of the hinge cap is opened, the knob portion Sa of the seal S adhered to the partition wall 29 of the inner plug member D is picked with a finger, and the seal S is separated from the partition wall The spout 35 and the air inlet 36 formed in the non-sealed recess 29 b of the partition wall 29 are opened.

  Next, by tilting the container E in the pouring direction (opposite to the hinge C), the liquid content in the container E can be easily poured out from the spout 35 through the pouring cylinder 7 of the cap body A. it can.

  After use, by closing the lid B again, the sealing cylinder 22 of the lid B can be inserted into the inner periphery of the pouring cylinder 7 of the cap body A, and the inside of the cap body A can be sealed, and the hinge cap Even after opening, the lid B can be repeatedly opened and closed for use.

The hinge cap according to the present embodiment can be separated and discarded from the mouth portion 1 of the container E after all the content liquid in the container E is used.
At that time, when the lid B of the hinge cap is opened, the lid B is grasped with a finger and pulled upward, the outer peripheral wall portion 10 of the cap body A together with the hinge C is moved upward from the hinge C connecting portion. When pulled and pulled while breaking the weakened portion 12 with respect to the mounting cylinder portion 3, the container mounting portion 6 of the mounting cylinder portion 3 is pulled and deformed via the connecting portion 11 opposite to the hinge C. The fitting with the container E is removed, and the hinge cap and the container E can be separated and discarded.

  In this embodiment, the seal S is attached to the upper surface of the partition wall 29 of the inner plug member D, and the spout 35 and the air inlet 36 opened in the partition wall 29 are closed. You may make it open a spout in a partition by unplugging a division with a pull ring etc.

The hinge cap of the present invention has a stronger adhesion between the seal tube portion of the inner plug member and the inner periphery of the mouth of the container, and has a good shape retaining property of the lid engaging portion of the cap body. This is also suitable as a cap for stoppering when the container is made of a glass bottle or hard resin.
In addition, the hinge cap of the present invention is composed of two members, a cap and an inner plug member, and different synthetic resin materials can be selected for each, which is suitable as a heat-resistant cap.
