The knob portion 41 has a deformed recess 42 recessed from the upper surface in the base portion, and the grip portion 41 of the portion is a thin-walled deformed portion 41a, but the deformed recess 42 may not be recessed.

In the portion of the side peripheral wall 36 where the outer peripheral recess 40 is formed, the wall thickness is thinner than the wall thickness of the other portion, and in particular, the engaging recess recessed from the inner peripheral side of the side peripheral wall 36. The place where 39 is located is the thin wall portion 36a which is the thinnest.
On the lower surface of the knob portion 41, a sealing locking portion 43 is provided which engages with the sealing member F described later at the time of setting and separates the sealing member F from the cap body B at the time of opening the lid.

The sealing locking portion 43 is vertically provided from the lower surface of the knob portion 41, and is formed in an arc shape with the insertion wall portion 44 so that the inner side surface covers the front side of the outer peripheral wall portion 11 of the cap body B at the time of setting.

The sealing member F is integrally molded with the cap body B of the hinge cap A, which is separately molded, in a color different from that of the cap body B (indicated by hatching in the figure) by two-color molding. A sealing wall formed in the circumferential direction is provided with a space α into which the sealing locking portion 43 of the knob portion 41 is inserted from above between the outer peripheral surface of the outer peripheral wall portion 11 of the mounting portion 5 of the main body B on the front side. 50 and a covering portion 51 which is connected to the upper end of the outer periphery of the sealing wall 50 and covers the lower part of the knob portion 41 are provided.
The sealing wall 50 is provided with side walls 52 facing the outer peripheral wall portion 11 at both ends, and the side walls 52 are connected to the outer peripheral wall portion 11 via a breakable connecting portion 53, respectively.
The covering portion 51 is composed of a bottom wall portion 54 that covers the outer lower surface of the sealing locking portion 43 of the knob portion 41, and a side wall portion 55 that is erected on the outer edge of the bottom wall portion 54 and covers the outer surface of the knob portion 41. Has been done.

Next, the usage mode and the action and effect of this example will be described.
As shown in FIG. 2, the hinge cap A of this embodiment is injection-molded with the lid open, and then the forming area is switched by partially operating the mold, and the hinge cap A has a different color from that of the hinge cap A. The sealing member F (a pigment or the like is added to the same synthetic resin material as the hinge cap A) is integrally molded with the cap body B by two-color molding. As a result, the sealing member F and the cap body B are in a state where the connecting portion is welded.
The primary molded hinge cap A can be inserted into the mold, and the sealing member F can be integrally molded by so-called insert molding, in which the sealing member F is molded in two colors.

Next, the upper lid C is rotated with respect to the cap body B via the hinge D in the closing direction, and the engaging recess 39 of the side peripheral wall 36 of the upper lid C and the lid engaging portion 9 of the cap body B are fitted. And close the hinge cap A.
At the time of closing the lid, the sealing locking portion 43 hanging from the knob portion 41 of the upper lid C is inserted into the space α of the sealing member F from above, and is inserted into the fitting portion 45 of the sealing locking portion 43 on the inner surface of the sealing wall 50. The formed inclined lower surface 45a comes into contact with each other, and the insertion wall portion 44 is inserted into the space α while the fitting portion 45 slightly expands the sealing wall 50.

Finally, as shown in FIG. 1, the inside of the insertion wall portion 44 of the sealing locking portion 43 is close to the outer peripheral surface of the outer peripheral wall portion 11 of the cap body B, and the outer surface of the insertion wall portion 44 is the sealing wall. Along with contacting or approaching the inner surface of the 50, the step upper surface 45c of the fitting portion 45 engages with the lower end surface of the sealing wall 50 to maintain the closed state, and the covering portion 51 of the sealing member F is a knob portion. It covers other than the upper surface of 41.

Further, when the lid is closed, as shown in FIG. 3, the lower outer circumference of the sealing cylinder 37 of the upper lid C is sealed with the outer circumference of the sealing portion 37a in close contact with the lower inner circumference of the pouring cylinder 8 of the cap body B. The outer circumference of the lower seal portion 37b of the sealing cylinder 37 is temporarily sealed in close proximity to or in contact with the inner peripheral surface of the spout 7 and the upper inner peripheral surface of the upper side wall 20 of the rectifying cylinder G connected thereto.

The closed hinge cap A is attached to the mouth 1 of the container body E filled with the content liquid by a stopper or the like.
When the hinge cap A is closed and a pressing force is applied to the corners of the top wall 35 and the side peripheral wall 36 of the top lid C, especially when the container is tapped or the container with the top lid C down is dropped. It is possible to prevent the tip portion 37c of the sealing cylinder 37 of the upper lid C from coming into contact with the inclined surface 25a of the pressing convex portion 25 of the rectifying cylinder G, and the upper lid C from being crushed and deformed.

Further, when the inclined surface 25a is inclined outward with a downward slope, the force for pushing the tip portion 37c of the sealing cylinder 37 is divided into the outward force, and the sealing cylinder 37 is moved outward from the tip portion 37c. The container body is expanded by a seal formed by the seal portion 37a of the sealing cylinder 37 and the lower inner peripheral surface of the pouring cylinder 8 and a temporary seal formed by the lower sealing portion 37b and the inner peripheral surface of the pouring outlet 7. Since the sealing property inside E can be ensured, even if one of the seals is removed due to an impact, the other seal seals the seal and the content liquid does not leak.
Further, the tip end portion of the inner cylinder wall 38 of the upper lid C comes into contact with the upper surface of the upper wall 6 of the cap body B, and the upper lid C is prevented from being crushed and deformed.
As described above, even if the upper lid C is pushed against the cap body B when the stopper or the container is inverted and dropped, the inner cylinder wall 38 of the upper lid C and the upper wall 6 of the cap body B come into contact with each other and are densely packed. By receiving the tip portion 37c of the envelope 37 by the pressing portion 25, the upper lid C is prevented from being crushed and deformed with respect to the cap body B.

Since the rectifying cylinder G is provided at the spout 7 of the cap body B, even if the container is dropped when the hinge cap A is closed and the content liquid in the container body E shakes violently, the content liquid remains. The momentum is suppressed by hitting the bottom 23 and the lower side wall 22 of the rectifying cylinder G, and the content liquid that has entered from the discharge port 26 also hits the outer periphery of the protruding portion 24 to suppress the momentum. The top wall 35 inside the sealing cylinder 37 of the upper lid C is not pushed up vigorously to open the lid.

Further, since the covering portion 51 of the sealing member F covers other than the upper surface of the knob portion 41, it is possible to prevent the floor or the like from colliding with the lower surface and the tip portion of the knob portion 41 when the container is dropped and opening the lid.

In the container to which the hinge cap A of the present embodiment is attached, there is no gap between the thin wall 13 provided at the lower end of the outer peripheral wall portion 11 of the cap body B and the upper surface of the neck ring 3 of the container body E after tapping. Therefore, if the hinge cap A is forcibly removed from the container body E using a metal fitting or the like, the thin wall 13 of the outer peripheral wall portion 11 cannot withstand the deformation and breaks, leaving a mark. It is possible to prevent unauthorized opening due to such factors.

When the container to which the hinge cap A of the present embodiment is attached is used for the first time, first, a finger or the like is put on the lower surface of the bottom wall portion 54 of the covering portion 51 of the sealing member F, and the covering portion 51 is lifted upward.
When the bottom wall portion 54 is lifted, the knob portion 41 of the upper lid C that comes into contact with the upper surface is also lifted from below.
In the grip portion 41, the thin-walled deformed portion 41a formed by the deformed recess 42 recessed in the base portion is easily deformed. Therefore, as shown in FIG. The deformed portion 41a serves as a fulcrum, and the tip end side of the knob portion 41 is lifted upward together with the covering portion 51.

When the knob 41 is lifted upward from the tip side together with the covering portion 51, the continuous sealing locking portion 43 is also lifted so that the lower portion faces outward and upward, and accordingly, engages with the sealing locking portion 43. The sealing wall 50 of the sealing member F is also lifted so that the lower portion faces outward and upward.
Further, when the sealing wall 50 is lifted, the side walls 52 on both sides connected to the sealing wall 50 are also lifted in conjunction with each other, and the connecting portions 53 connected to the outer peripheral wall portion 11 of the cap body B are connected from below. It is broken and the sealing member F is separated from the cap body B.
The sealing member F is lifted so that the lower part faces outward and upward as a whole by lifting the covering portion 51 and lifting the sealing wall 50 by the sealing locking portion 43, and is separated from the outer peripheral wall portion 11 of the cap body B. Therefore, the sealing member F can be reliably separated from the cap body B.

After the sealing member F is separated, when the knob portion 41 is further lifted together with the covering portion 51, the thin wall portion 36a of the side peripheral wall 36 is also deformed and lifted with the thin wall portion 36a as a fulcrum. The engagement recess 39 of the side peripheral wall 36 near 36a and the lid engaging portion 9 are disengaged, and then the engaging recess 39 of the other side peripheral wall 36 and the lid engaging portion 9 are fitted. The case is removed from the thin wall portion 36a side, and the upper lid C is opened as shown in FIG. 4 (b).
Since the wall of the thin wall portion 36a of the side peripheral wall 36 of the upper lid C is also deformed when the lid is opened, the engagement recess 39 of the upper lid C and the lid engaging portion 9 of the cap body B can be fitted. Even if it is strong, the lid can be opened easily and with a weak force.
Further, since the sealing member F is separated from the cap body B after the lid is opened, it can be easily removed from the knob portion 41 and the sealing locking portion 43 of the upper lid C.

As described above, in the hinge cap A of the present embodiment, the sealing member F is first separated from the cap body B by lifting the covering portion 51 of the sealing member F at the time of the first opening, and then the upper lid C is opened. Since the lid is closed, the sealing member F is always separated after the lid is opened, and unauthorized opening can be prevented by visually recognizing the presence or absence of the sealing member F.
Further, the hinge cap A and the sealing member F are color-coded in different colors, and the presence of the sealing member F is conspicuous with respect to the hinge cap A, so that the presence or absence of the sealing member F is more easily understood.

When the content liquid is used, since the protrusion 24 is erected from the bottom 23 of the rectifying cylinder G, the container is tilted greatly, and even if the content liquid vigorously flows inward from the discharge port 26, it protrudes. The momentum is suppressed by hitting the groove 30 on the outer periphery of the cylinder wall 28 of the portion 24, and the rectified content liquid can be dispensed from the dispensing cylinder 8.
Since the air replacement hole 27 is provided on the back side of the rectifying cylinder G, even if the container is tilted greatly and the discharge port 26 is blocked by the content liquid, air flows into the container body E from the air replacement hole 27. Since the air is replaced, the content liquid can be stably poured out without pulsating.
Next, when the use of the content liquid is finished, by erecting the container, the content liquid remaining in the pouring cylinder 8 flows down into the rectifying cylinder G and can be collected from the discharge port 26 into the container body E. , The content liquid hardly remains in the pouring cylinder 8 and the rectifying cylinder G.

In the hinge cap of the present invention, when the hinge cap is illegally opened, the sealing member having a color different from that of the cap body is separated from the cap body. Therefore, it can be widely used as a hinge cap for various containers.
