Is in contact with the inner surface of the top wall 11 of the upper lid D, but the upper surface of the central protrusion 20 is in close proximity to the inner surface of the top wall 11 with a slight gap.
Therefore, at the time of closing, an upper air gap 21 surrounded by the peripheral projection 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 upper surface of the plug E comes in contact with the inner surface of the top wall 11, a side gap S1 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 Also, an upper and lower gap S2 is formed between the upper end of the locking portion 13a of the cylindrical wall 13 and the lower surface of the plug base 17.
By forming these gaps S1 and S2, the plug E is held inside the cylindrical wall 13 of the upper lid D with rattling in the vertical and horizontal directions.

Next, usage modes and effects of the present embodiment will be described.
The hinge cap according to the present embodiment is mounted on the cylindrical wall 13 of the upper lid D in a state in which the upper lid D is opened, and the sealing ring 18 of the stopper E is mounted on the inner periphery of the dispensing cylinder 5 of the cap main body B. When the upper lid D is closed with the tip portion 18a inserted and then the hinge C as a rotation center, the cylindrical wall 13 covers the plug base 17 and the upper lid D is further closed. The outer peripheral surface passes over the locking portion 13 a on the inner periphery of the cylinder wall 13 and is held by the cylinder wall 13.
Next, as shown in FIG. 1, in a state in which the upper lid D is closed with respect to the cap main body B, the container 1 is plugged and attached to the opening 1 of the container A filled with contents.
In the plugging process, the opening 1 of the container A is placed on the annular groove formed between the inner cylinder 8 and the outer cylinder 9 of the mounting unit 3, and a pressing force is applied from above the upper lid D. The engagement ridges 10 of the second embodiment are fitted over the fitting ridges 2 of the mouth portion 1 and the mouth portion 1 of the container A is held by the outer circumference of the inner cylinder 8 and the inner circumference of the outer cylinder 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, but in the present embodiment, the lower end 13 b of the cylindrical wall 13 is the upper wall 4 of the cap body B. Because the top wall 11 is deformed and the lower end 13 b abuts on the upper wall 4 because the top wall 11 is in close proximity or in contact with the upper surface, the further deformation can be prevented.
Furthermore, since the tip 18a of the sealing ring 18 of the plug E is in close proximity to or in contact with the ridge step 5a of the dispensing cylinder 5, when a downward force is applied to the top wall 11, the tip 18a is Contact with the ridge step 5 a can prevent the sealing ring 18 from biting further into the inner periphery of the pouring barrel 5, and maintain a good seal between the sealing ring 18 and the pouring barrel 5 Can. If the projecting step 5a is not provided in the pouring barrel 5, the sealing ring 18 is pushed into the inner periphery of the pouring barrel 5 and the seal with the pouring barrel 5 is damaged.
At this time, it is preferable that the tip end portion 18a of the sealing ring 18 be in close proximity to the protruding ridge portion 5a with a slight gap, and the gap is particularly preferably 0.1 to 0.5 mm.
In the present embodiment, the mounting portion 3 holds the opening 1 of the container A by the outer periphery of the inner cylinder 8 and the inner periphery of the outer cylinder 9, and the base wall 7, but the opening of the container A is An external thread may be formed on the outer periphery of the portion 1 and a female thread may be formed on the inner periphery of the outer cylinder 9 for screwing.

As described above, in the closed state, the plug E is integrated with the dispensing cylinder 5 of the cap main body B by fitting the sealing ring 18 into the inner periphery of the dispensing cylinder 5, and the container A falls Even when an external force is applied to the upper lid D and an upper or lower lateral displacement occurs in the upper lid D due to an impact such as time or falling as shown in FIG. 3 and FIG. By forming the side gaps S1 and the upper and lower gaps S2 on the inner periphery of the cylinder wall 13 and the inner surface of the top wall 11, the influence on the movement of the upper lid D is alleviated, and the airtightness of the container A can be maintained. .
Further, the plug body E has a thin upper wall 21 except for the peripheral protrusion 19 and the central protrusion 20 of the plug base 17 because the upper gap 21 is formed on the upper surface of the plug base 17. When a force is applied from the upper lid D, the force applied to the sealing cylinder 18 can be dispersed by deformation.
Furthermore, the central projection 20 of the plug base 17 can reduce the impact force by receiving the force applied from the top wall 11 of the upper lid D to the plug E at pin point when the container A falls or falls. it can.
In the present embodiment, as shown in FIG. 5 (a), the peripheral projection 19 is formed over the entire periphery of the upper surface peripheral portion of the plug base 17, but may be formed intermittently, or The central protruding portion 20 is formed at only one place at the center of the upper surface of the plug base 17, but a plurality of central protrusions 20 may be formed evenly around the center.
In addition, as described in the plugging process, the sealing ring 18 of the plug body E is sealed in combination with the tip 18a being in close proximity to the projecting step 5a of the pouring barrel 5 with a slight gap. The plug base portion 17 on which the ring 18 is provided is easily deformed at the portion where the upper gap 21 is formed, so that the plug base portion 17 is deformed even when the upper lid D is deformed when the container A falls or falls. The seal ring 18 itself does not deform only by deformation of the portion where the upper air gap 21 is formed, and the tip end portion 18a slightly descends and abuts against the ridge step portion 5a, and the further lowering stops By doing this, the seal between the sealing ring 18 and the inner periphery of the pouring barrel 5 can be maintained.

In order to open the cap of this 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 When the knob portion 16 is lifted upward, the cylindrical wall 13 of the upper lid D is lifted, and the locking portion 13a is lifted by coming into contact with the outer edge portion of the plug base 17, and the cap body The sealing ring 18 can be removed from the dispensing cylinder 5 of B 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 E interlocked with the upper lid D is removed from the dispensing cylinder 5 of the cap body B. For example, only by tilting the container A, the contents in the container A can be easily poured out of the pouring barrel 5.

Next, after the use of the container A is finished, when the upper lid D is closed, the sealing ring 18 of the plug E is fitted into the inner periphery of the dispensing cylinder 5, and the plug E is combined with the dispensing cylinder 5 of the cap main body B After integration, the convex portion 14 of the side wall 12 and the engagement concave portion 15 are fitted so as to sandwich the lid engaging portion 6 of the cap main body B, and return to the closed state.
At this time, in the upper lid D, the convex portion 14 and the engagement concave portion 15 sandwich the lid engaging portion 6 of the cap main body B, and the lower end of the side wall 12 is applied even when a force is applied to the upper lid D It is possible to prevent the part from being dislocated and deformed.
In this manner, a hinge cap capable of sealing the dispensing cylinder 5 any number of times 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 falling or falling. In such a case, the excellent effect that the airtightness in the container A can be maintained is exhibited.
In addition, the position of the dispensing cylinder 5 can be appropriately changed even if it is not at the center of the upper wall 4 of the cap main body B, and in other words, the one opposite to the hinge C is eccentric. It is convenient to pour out the contents from the pouring barrel 5.

In addition, the entire hinge cap may be made of the same synthetic resin, but when the plug E is made of a hard synthetic resin than the synthetic resin of the cap main body B and the upper lid D, the plug E is the inner periphery of the pouring cylinder 5 It is easy to get in and the air tightness improves.
Furthermore, the container A may be made of any material, and the content stored in the container is not limited to liquid, and may be powder, granules or the like.
According to the present invention, the contents in the container can be kept airtight for a long time.

  The hinge cap according to the present invention comprises a plug body separately formed from the cap body and the upper lid, and the sealing ring of the plug body is inserted into and integrated with the discharge pipe of the cap body, and the container is sealed. Even when a force is applied to the upper lid due to a fall or a drop, the airtightness of the container can be maintained since the structure does not affect the stopper. In addition, because it is easy to open and close any number of times and has good resealability, it can be applied not only to liquid detergents, foods, seasonings, but also to powdery ones. It is suitable as a container for storing the necessary contents.
