As shown in FIGS. 1 and 4, the plug E is used to seal the pouring tube 5 when the lid is closed, and is configured as a separate member from the cap body B and the upper lid D.
As shown in FIG. 5, the plug E is suspended from the disc-shaped plug base 17 and the lower surface of the plug base 17 and is fitted into the inner periphery of the dispensing cylinder 5 of the cap body B from the tip 18 a. And a sealing ring 18.
In the present embodiment, a tapered surface is formed on the upper end of the outer periphery of the plug base 17, and when the plug E is inserted inside the cylindrical wall 13, it is easy to overcome the above-described gentle inclination of the locking portion 13 a. doing.

A peripheral protrusion 19 and a central protrusion 20 are formed on the upper surface peripheral portion and the upper surface central portion of the plug base 17, respectively, and as shown in FIG. 4A, the upper surface of the peripheral protrusion 19 in the closed state. Is in contact with the inner surface of the top wall 11 of the upper lid D, but the upper surface of the central projection 20 is close to the inner surface of the top wall 11 with a slight gap.
For this reason, the upper space | gap 21 enclosed by the peripheral protrusion 19 is formed between the upper surface of the plug base 17 and the inner surface of the top wall 11 at the time of closing.
When the lid is closed, when the upper surface of the plug E comes into contact with the inner surface of the top wall 11, a side gap S 1 is formed between the inner peripheral surface of the cylindrical wall 13 of the upper lid D and the outer peripheral surface of the plug base 17. In addition, a vertical gap S <b> 2 is also formed between the upper end of the locking portion 13 a of the cylindrical wall 13 and the lower surface of the plug base portion 17.
By forming these gaps S1 and S2, the plug E is held with back and forth in the vertical and horizontal directions inside the cylindrical wall 13 of the upper lid D.

Next, usage modes and operational effects of this embodiment will be described.
The hinge cap according to the present embodiment has the sealing ring 18 of the plug E attached to the inner periphery of the pouring cylinder 5 of the cap body B with the upper cover D opened when the plug E is assembled to the cylinder wall 13 of the upper cover D. When the distal end portion 18a is inserted and then the upper lid D is closed with the hinge C as the center of rotation, the cylindrical wall 13 covers the plug base 17 and when the upper lid D is further closed, the plug base 17 The outer peripheral surface gets over the locking portion 13 a on the inner periphery of the cylindrical wall 13 and is held by the cylindrical wall 13.
Next, as shown in FIG. 1, the cap body B is plugged into the mouth 1 of the container A filled with the contents with the upper lid D closed.
In the plugging step, the mouth portion 1 of the container A is applied to the annular groove formed between the inner cylinder 8 and the outer cylinder 9 of the mounting portion 3, and a pressing force is applied from above the upper lid D. The engagement protrusion 10 is fitted over the fitting protrusion 2 of the mouth portion 1, and the mouth portion 1 of the container A is sandwiched between the outer periphery of the inner tube 8, the inner periphery of the outer tube 9, and the base wall 7. It is installed by being done.

In the plugging process, when a pressing force is applied from above the upper lid D, the top wall 11 is deformed downward. In this embodiment, the lower end portion 13b of the cylindrical wall 13 is formed on the upper wall 4 of the cap body B. Since the top wall 11 is deformed or is in contact with the upper surface, the top wall 11 is deformed, and the lower end portion 13b is in contact with the upper wall 4 to prevent further deformation.
Furthermore, since the front end portion 18a of the sealing ring 18 of the plug E is close to or in contact with the protruding step portion 5a of the dispensing tube 5, when a downward force is applied to the top wall 11, the front end portion 18a is Abutting against the protruding step portion 5a, it is possible to prevent the sealing ring 18 from further biting into the inner periphery of the dispensing cylinder 5, and to maintain a good seal with the sealing ring 18 and the dispensing cylinder 5 Can do. If the protruding step 5a is not provided in the extraction cylinder 5, the sealing ring 18 is pushed into the inner periphery of the extraction cylinder 5, and the seal with the extraction cylinder 5 is damaged.
At this time, the tip 18a of the sealing ring 18 is preferably close to the protruding step 5a with a slight gap, and this gap is particularly preferably 0.1 to 0.5 mm.
In the present embodiment, the mounting portion 3 holds the mouth portion 1 of the container A by the outer periphery of the inner tube 8, the inner periphery of the outer tube 9, and the base wall 7. While forming an external thread in the outer periphery of the part 1, you may screw together by forming an internal thread in the inner periphery of the outer cylinder 9.

As described above, in the closed state, the sealing ring 18 is fitted into the inner periphery of the pouring cylinder 5 so that the plug E is integrated with the pouring cylinder 5 of the cap body B, and the container A falls over. Even when an external force is applied to the upper lid D due to an impact such as time or dropping, as shown in FIG. 3 and FIG. By forming the side gap S1 and the vertical gap S2 on the inner periphery of the cylindrical wall 13 and the inner surface of the top wall 11, respectively, the influence on the movement of the upper lid D is mitigated, and the airtightness of the container A can be maintained. .
Further, the plug body E has an upper gap 21 formed on the upper surface of the plug base 17 and is thin except for the peripheral protrusion 19 and the central protrusion 20 of the plug base 17, so that the plug base 17 When receiving a force from the upper lid D, the force applied to the sealing cylinder 18 can be dispersed by being deformed.
Further, the central projecting portion 20 of the plug base 17 can relieve the impact force by pinpointing the force applied to the plug E from the top wall 11 of the upper lid D when the container A falls or falls. it can.
In the present embodiment, the peripheral protrusion 19 is formed over the entire periphery of the upper peripheral surface of the plug base 17 as shown in FIG. 5A, but may be formed intermittently. The central projecting portion 20 is formed only at one central portion of the top surface of the plug base portion 17, but a plurality of central projecting portions 20 may be formed so as to be evenly arranged around the central portion.
Further, as described in the plugging process, the sealing ring 18 of the plug body E is sealed in combination with the tip portion 18a being close to the protruding step portion 5a of the dispensing cylinder 5 with a slight gap therebetween. The plug base 17 that suspends the ring 18 is easily deformed at the portion where the upper gap 21 is formed, so that even if the upper lid D is deformed when the container A falls or falls, the plug base The portion where the upper gap 21 is formed is only deformed, the sealing ring 18 itself is not deformed, the tip 18a is slightly lowered and comes into contact with the ridge step 5a, and further lowering stops. By doing so, the seal between the sealing ring 18 and the inner periphery of the dispensing cylinder 5 can be maintained.

To open the cap of the present embodiment, as shown in FIG. 3, the knob 16 of the upper lid D is pushed up from the state shown in FIG. 1, and the engaging recess 15 of the upper lid D and the lid engaging portion 6 of the cap main body B are lifted. When the knob portion 16 is released and the knob portion 16 is lifted upward, the cylindrical wall 13 of the upper lid D rises and the locking portion 13a comes into contact with the outer edge portion of the plug base portion 17 and is lifted. The sealing ring 18 can be removed from the B-pouring cylinder 5 and the lid is opened as shown in FIG.
In this embodiment, without removing the plug, the knob 16 of the upper lid D is lifted from the closed state, and the sealing ring 18 of the plug body E interlocked with the upper lid D is removed from the dispensing cylinder 5 of the cap body B. In this case, the contents in the container A can be easily poured out from the dispensing cylinder 5 simply by tilting the container A.

Next, after the use of the container A is finished, when the upper lid D is closed, the sealing ring 18 of the plug body E is fitted into the inner periphery of the pouring cylinder 5, and the plug body E is connected to the pouring cylinder 5 of the cap body B. After the integration, the convex portion 14 and the engaging concave portion 15 of the side wall 12 are fitted so as to sandwich the lid engaging portion 6 of the cap body B, and the lid is returned to the closed state.
At this time, in the upper lid D, the convex portion 14 and the engaging concave portion 15 sandwich the lid engaging portion 6 of the cap body B, and even if a force is applied to the upper lid D at the time of falling or dropping, the lower end of the side wall 12 It is possible to prevent the portion from being displaced and deformed.
In this way, a hinge cap capable of sealing the dispensing cylinder 5 as many times as possible is obtained. In the closed state, the plug E is integrated with the cap body B, and a force is applied to the upper lid D by overturning or dropping. Even in such a case, there is an excellent effect that the airtightness in the container A can be maintained.
The position of the dispensing cylinder 5 can be changed as appropriate even if it is not at the center of the upper wall 4 of the cap main body B. If it is rather eccentric to the opposite side of the hinge C, It is convenient to pour the contents from the pour tube 5.

The entire hinge cap may be made of the same synthetic resin. However, when the plug body E is made of a synthetic resin harder than the synthetic resin of the cap body B and the upper lid D, the plug body E is the inner periphery of the dispensing cylinder 5. It becomes easy to fit in and improves airtightness.
Further, the container A may be made of any material, and the contents stored in the container are not limited to liquid, and may be powdered or granular.
According to the present invention, the contents in the container can be kept airtight for a long time.

  The hinge cap of the present invention is provided with a cap body that is configured separately from the cap body and the upper lid, and the sealing ring of the plug body is integrated by being fitted into the extraction cylinder of the cap body, whereby the container is sealed, Even when force is applied to the upper lid due to falling or dropping, the container has a structure that does not affect the stopper, so that the airtightness of the container can be maintained. In addition, since it can be easily opened and closed many times and has good resealability, the contents can be applied not only to liquid cleaning materials, foods, seasonings, but also to powdered materials, especially airtight. It is suitable as a container for storing necessary contents.
