The hinge cap of this embodiment is an unplugging-less cap, and although not shown, a shrink label, a sealing member, etc., are used between the cap body B and the lid D to prevent unauthorized opening before use. Is provided.
Further, in this embodiment, the hinge cap has been described as a specific example of the unplugging-less cap, but the present invention is not limited to this embodiment, and a screw cap including a cap body and a lid may be used.

Next, the usage mode and the action and effect of this example will be described.
The hinge cap of this embodiment first rotates the lid D through the hinge C from the state shown in FIG. 2, covers the cap body B, and closes the lid.

At that time, the lower part of the outer circumference of the seal cylinder 32 of the lid body D is in close contact with the inner circumference of the injection cylinder 5 of the cap body B, and the lower part of the inner circumference of the seal cylinder 32 is in contact with the outer circumference of the convex holding portion 26. As a result, the pouring cylinder 5 and the convex holding portion 26 sandwich the lower portion of the seal cylinder 32.
Further, during the closing of the lid, the outer cylinder 33 of the lid body D descends from the hinge C side toward the guide convex portion 28 of the base wall 4 of the cap body B, and then the outer cylinder 33 of the outer cylinder 33 of the guide convex portion 28. While being guided by the outer peripheral surface, the tip portion 33a of the outer cylinder 33 is inserted into the engaging recess 16 of the base wall 4, and the inner circumference of the tip portion 33a abuts on the engaging surface 4d.

The guide convex portion 28 erected on the base wall 4 may be omitted.
Further, when the outer cylinder 33 is inserted into the engaging recess 16, the outer cylinder 33 may be in close contact with or in contact with the engaging surface 4d.

Next, as shown in FIG. 1, the closed hinge cap is attached by tapping the mouth portion 1 of the container A filled with the content liquid.
In the plugging step, the mouth portion 1 of the container A is applied to the annular groove formed between the inner cylinder 8 of the mounting portion 3 and the outer peripheral wall portion 9, and a pressing force is applied from above the lid body D to apply a pressing force to the outer circumference. The engaging protrusion 10 of the wall portion 9 gets over the fitting protrusion 2 of the mouth portion 1 and is fitted, and the mouth portion 1 of the container A is the outer circumference of the inner cylinder 8, the inner circumference of the outer peripheral wall portion 9, and the lid. It is attached by being sandwiched by the joint portion 7.

In this embodiment, the mounting portion 3 sandwiches the mouth portion 1 of the container A by the outer circumference of the inner cylinder 8, the inner circumference of the outer peripheral wall portion 9, and the base wall 4, but the container A It may be screwed by forming a male screw on the outer circumference of the mouth portion 1 and forming a female screw on the inner circumference of the outer peripheral wall portion 9.

As described above, in the closed state, the seal cylinder 32 of the lid body D is sandwiched between the inner circumference of the injection cylinder 5 of the cap body B and the outer circumference of the convex holding portion 26, so that the seal cylinder 32 Is integrated with the pouring cylinder 5 of the cap body B, and when an external force is applied to the lid D due to an impact such as the container A tipping over or dropping, the lid D is displaced in the vertical or horizontal direction. However, the influence on the movement of the lid D is alleviated, and the airtightness of the container A can be maintained.

In the hinge cap of this embodiment, when a pressing force is applied to the lid D from above due to an impact such as dropping in the closed state, the lid D is pushed against the cap body B, but the lid D The locking convex portion 34 provided at the lower end of the side peripheral wall 31 of the cap body B is engaged with the inner peripheral side of the lid engaging portion 7 of the cap body B, so that the lower end of the side peripheral wall 31 of the lid D is engaged. Can be prevented from spreading outward and deforming.

Further, even if a pressing force is applied from the side of the lid D due to an impact such as dropping, the inner surface of the tip portion 33a of the outer cylinder 33 is closely fixed to the engaging surface 4d of the base wall 4. Therefore, it is possible to prevent the seal cylinder 32 from moving together with the lid D due to an impact.
As described above, in the hinge cap of the present embodiment, the impact received by dropping or the like is suppressed by providing the convex holding portion 26 inside the pouring cylinder 5 of the cap body B, and the hinge cap of the lid D and the seal cylinder 32 Since it does not affect the close contact of the cap body B with the pouring cylinder 5, it is possible to prevent the cap body B from coming off and the seal cylinder 32 and the pouring cylinder 5 from being damaged by each other.

When opening the hinge cap for the first time in order to use the content liquid in the container A for the first time, the shrink label and the sealing member provided between the cap body B and the lid D are removed, although not shown. There is a need.

Next, when a finger is hung on the finger hook portion 37 of the lid body D and the handle portion 36 is lifted, the seal cylinder 32 of the lid body D is removed from the pinched state by the pouring cylinder 5 of the cap body B and the convex holding portion 26. As a result, the content liquid in the container A can be easily poured out from the pouring cylinder 5 simply by tilting the container A.
Further, since the lid body D is formed to have a thin wall on the side opposite to the hinge C of the engaging recess 35 provided on the side peripheral wall 31, when the handle portion 36 is lifted when the lid is opened, the engaging recess 35 of the side peripheral wall 31 is formed. Is deformed, the resistance of the lid engaging portion 7 to the locking ridge 6 is reduced, and the lid can be opened smoothly.

In this embodiment, since the flow rate adjusting mechanism E is provided at the lower end portion 5a of the pouring cylinder 5 of the cap body B, the content liquid in the container A is poured out from the pouring cylinder 5 after adjusting the flow rate. ..
The flow rate adjusting mechanism E does not necessarily have to be provided.

When the pouring of the content liquid is completed, the content liquid in the pouring cylinder 5 is returned to the container A from the stepped portion 5b and the notch inclined portion 27 through the flow rate adjusting mechanism E, and also travels along the inner circumference of the peripheral wall 20 to the bottom wall. The pouring cylinder 5 because it falls on the upper surface of 21 and flows along the inclined surface by the bottom wall 21 slightly inclined toward the hinge C side and is returned into the container A through the air replacement hole 23 on the hinge C side. And almost no liquid remains in the flow rate adjusting mechanism E.
Since the notch inclined portion 27 is provided in the step portion 5b of the dispensing cylinder 5 in this way, it is difficult for the content liquid to collect between the dispensing cylinder 5 and the convex holding portion 26, and the liquid is difficult to collect when the lid D is opened and closed. Bounce can be prevented.

By closing the lid D to the cap body B again, the lower part of the outer circumference of the seal cylinder 32 of the lid D comes into close contact with the inner circumference of the injection cylinder 5 of the cap body B, and the lower part of the inner circumference of the seal cylinder 32 becomes in close contact with the inner circumference. The inside of the cap body B can be sealed by abutting on the convex holding portion 26, and the hinge cap can be used by repeatedly opening and closing the lid body D.

The hinge cap of this embodiment can be separated from the mouth 1 of the container A and discarded after all the contents of the container A are used.
In that case, when the hinge cap is opened, the lid D is grasped with a finger and pulled outward, the portion of the outer peripheral wall portion 9 connected to the hinge C is pulled and deformed, and the vertical tear line is formed. Is broken, and when the lid D is further pulled, the connecting portion 15 forming the circumferential tear line begins to break. As the breaking of the connecting portion 15 progresses, the lid body D separates from the cap body B.
When the cutting of the connecting portion 15 is completed up to the end of the slit groove 13 and the lid D is further pulled, the cap body B and the mouth portion 1 of the container A are disengaged, and the hinge cap and the container A are separated. Can be discarded.

Next, a second embodiment in which the shape of the seal cylinder holding portion of the cap body B of the first embodiment is changed will be described with reference to the drawings.
Hereinafter, the same components as those in the first embodiment will be designated by the same reference numerals, and the changed portions of the plug body will be designated by new reference numerals, and the differences will be mainly described.

In FIG. 3, A is a container, Ba is a cap body attached to the container A, C is a hinge, and D is a lid body openably and closably attached to the cap body Ba via a hinge C.

The cap body Ba extends inward from the mounting portion 3 mounted on the mouth portion 1 of the container A and the upper end of the inner edge of the mounting portion 3, and the base wall 4 having a step formed to close the opening of the mouth portion 1. It is provided with a pouring cylinder 5 which is erected from around the spout that penetrates the base wall 4, and a flow rate adjusting mechanism Ea which is continuously provided at the lower end portion 5a of the pouring cylinder 5.
The inner circumference of the dispensing cylinder 5 has a reduced diameter at the lower portion and is provided with a step portion 5b, and the cross-sectional shape of the step portion 5b is formed on an inclined surface having a gentle downward slope toward the inside.

As shown in FIGS. 3 and 4, the flow rate adjusting mechanism Ea has the same structure as that of the first embodiment, and has a peripheral wall 20 suspended from the lower end portion 5a of the dispensing cylinder 5 and the inside of the lower end portion of the peripheral wall 20. It is provided with a bottom wall 21 extending toward the side.
The peripheral wall 20 is provided with a plurality of peripheral wall openings 22 formed in a vertical slit shape at intervals from the central portion on the opposite side of the hinge C to both sides to a predetermined range, and is provided on the hinge C side. Is provided with at least one air replacement hole 23 having the same opening area as the peripheral wall opening 22.
Further, the bottom wall 21 is provided with at least one bottom wall opening 24, which is biased toward the pouring side.

Inside the stepped portion 5b of the dispensing cylinder 5, an annular holding portion 29 arranged in a circumferential shape is erected as a sealing cylinder holding portion at a predetermined interval from the inner circumference of the dispensing cylinder 5, and the annular holding portion 29 is erected. A liquid return hole 25 is provided on the outside of the portion 29, that is, on the step portion 5b of the pouring cylinder 5 so as to communicate with the peripheral wall opening 22 or the air replacement hole 23 of the flow rate adjusting mechanism Ea.
In this embodiment, the liquid return holes 25 are provided at four locations at 90 ° intervals, but any number of liquid return holes 25 may be provided as long as there is at least one location.

Next, the usage mode and the action and effect of this example will be described.
The hinge cap of this embodiment first rotates the lid D from the state shown in FIG. 4 via the hinge C, covers the cap body Ba, and closes the lid.

At that time, the lower outer circumference of the seal cylinder 32 of the lid D is in close contact with the inner circumference of the injection cylinder 5 of the cap body Ba, and the lower inner circumference of the seal cylinder 32 is in contact with the outer circumference of the annular holding portion 29. As a result, the pouring cylinder 5 and the annular holding portion 29 sandwich the lower portion of the seal cylinder 32.

Next, as shown in FIG. 3, the closed hinge cap is attached by tapping the mouth portion 1 of the container A filled with the content liquid.

As described above, in the closed state, the seal cylinder 32 of the lid body D is sandwiched between the inner circumference of the injection cylinder 5 of the cap body Ba and the outer circumference of the annular holding portion 29, so that the seal cylinder 32 is formed. , It is integrated with the pouring cylinder 5 of the cap body Ba, and even if an external force is applied to the lid D due to an impact such as the container A tipping over or dropping, and the lid D is displaced in the vertical or horizontal direction. , The influence on the movement of the lid D is alleviated, and the airtightness of the container A can be maintained.

In this embodiment, since the flow rate adjusting mechanism Ea is provided at the lower end 5a of the pouring cylinder 5 of the cap body Ba, the content liquid in the container A is poured out from the pouring cylinder 5 after adjusting the flow rate. ..
The flow rate adjusting mechanism Ea does not necessarily have to be provided as in the first embodiment.

When the pouring of the content liquid is completed, the content liquid remaining in the pouring cylinder 5 is returned to the container A from the liquid return hole 25 formed in the step portion 5b through the peripheral wall opening 22 of the flow rate adjusting mechanism Ea. The content liquid remaining in the flow rate adjusting mechanism Ea falls on the upper surface of the bottom wall 21 along the inner circumference of the peripheral wall 20, and flows along the inclined surface by the bottom wall 21 slightly inclined toward the hinge C side. Since it is returned to the container A through the air replacement hole 23 on the hinge C side, almost no liquid remains in the pouring cylinder 5 and the flow rate adjusting mechanism Ea.
Since the liquid return hole 25 is provided in the stepped portion 5b of the dispensing cylinder 5 in this way, it is difficult for the content liquid to collect between the dispensing cylinder 5 and the annular holding portion 29, and the liquid splashes when the lid D is opened and closed. Can be prevented.
The action and effect of other configurations are the same as those in the first embodiment.

The unplugging-less cap of the present invention reduces the influence on the movement of the lid even when an external force is applied to the lid due to an impact such as dropping while the lid is closed and the lid is displaced in the vertical or horizontal direction. Since the airtightness of the container can be maintained, it can be easily opened and closed many times, and it has excellent resealability, it is particularly suitable as an unplugging-less cap for a container that stores contents that require particularly airtightness.
