That is, when the pressing plate 50 is positioned to protrude upward, which is a position that is not pressed, the connecting portion 56 maintains the current position of the pressing plate 50 while maintaining the convex dome shape. In addition, pressing the pressing plate 50 by a predetermined force or more maintains the pressing position of the pressing plate 50 while being elastically deformed in a concave shape.

The operation of the child protection stopper according to the present invention configured as described above will be described below.

10 and 11 is an operation state diagram of the child protection plug according to the invention.

In order to discharge the contents stored in the container 10 to the outside, the user presses the protective plate 13 connected to the external stopper 16 downward with a predetermined force, and a connecting rib connected between the protective plate 13 and the external stopper 16. While the 17 is broken, the protective plate 13 is moved downward and presses the pressing plate 50 of the sealing member removing unit 22. At this time, as the guide rib 15 of the S-shape connected between the protective plate 13 and the external stopper 16 is unfolded, the protective plate 13 is guided to move downward and the protective plate 13 is connected to the external stopper ( 16) Keep connected.

Then, when the pressing plate 50 is moved downward by the protective plate 13, the connecting portion 56 is elastically deformed and the pressing plate 50 is moved downward. Then, the first cutting portion 62 of the cutters 52 formed on the lower surface of the pressing plate 50 penetrates through the edge of the sealing member 20, and at the same time, the support rod 66 of the locking portion 54. Enters through the center of the sealing member (20).

At this time, the locking projection 68 of the locking portion 54 is bent upward when entering the sealing member 20 enters the hole punched by the punch portion 70 of the support rod 66. When the locking projection 68 enters the inside of the sealing member 20, the locking protrusion 68 is positioned on the inner surface of the sealing member 20 in a state in which it is elastically deformed and unfolded.

After such action, holding the outer cap 16 and applying a predetermined force or more to move downward, the outer member 16 moves while the elastic member 38 is elastically deformed. Then, between the first locking projections 40 formed on the inner stopper 14, the second locking projections 42 formed on the outer stopper 16 are inserted into each other so as to be engaged with each other. When turned, the rotational force of the outer stopper 16 is transmitted to the inner stopper 14 so that the inner stopper 14 is rotated and separated from the container inlet 12.

At this time, while the cutter 52 is rotated in contact with the inner circumferential surface of the container inlet 12, the second cutting part 64 formed on both sides of the support part 60 cuts the sealing member 20 in a circular shape. . In addition, since the sealing member 20 removed from the container inlet 12 is caught in the locking projection 68 of the locking portion 54, the sealing member 20 is separated from the container inlet 12 like the inner stopper 14 to be separated from the inside. It is housed inside the stopper 14.

As such, after discharging the contents stored in the container 10 from which the sealing member 20 is removed to the outside through the container inlet 12, the cap is closed again at the container inlet 12, and the elastic member 38 is closed. By the elastic force of the outer stopper 16 is moved to the relatively upward direction from the inner stopper 14, and thus the state between the first catching projection 40 and the second locking projection 42 is separated from each other Can be maintained so that even if the child turns the outer stopper 16, the rotational force is not transmitted to the inner stopper (14).

In addition, even if the child moves the outer stopper 16 in the downward direction, since the force is weak, the elastic force of the elastic member 38 does not allow the outer stopper 16 to move completely downward, and in this state Even if the stopper 16 is rotated, the inner stopper 14 is not opened because the inclined surface 46 of the second catching protrusion 42 rides over the inclined surface 46 of the first catching protrusion 40.

In this state, when the outer stopper 82 is rotated, the outer stopper 82 and the spline-coupled inner stopper 80 are rotated together and separated from the container inlet 12.

At this time, the sealing member removing unit 22 described in the above embodiment removes the sealing member 20 sealed at the container inlet 12 and accommodates the inside of the inner stopper 80.

Then, when the inner stopper 80 is closed on the container inlet 12 again, the second locking protrusions 100 formed on the inner circumferential surface of the outer stopper 82 are between the first locking protrusions 98 formed on the container inlet 12. The outer stopper 82 is locked so that the child cannot open the stopper.

The container stopper according to the present invention constructed and operated as described above is provided with a sealing member removing unit inside the inner stopper, and then pressing the pressing part of the sealing member removing unit and opening the stopper before opening the stopper to open the sealing member at the container inlet. It is easy to use because it is automatically removed.

In addition, by installing a protective plate on the upper surface of the outer stopper to protect the sealing member removing unit formed on the inner stopper, there is an advantage that the sealing member removing unit is exposed to the outside to prevent the sealing member removing unit from operating by external force. .

In addition, since the sealing member is automatically removed by the sealing member removing unit, when the sealing member is removed by hand, a hygienic problem due to hand contact with the container inlet can be solved.

In addition, since the elastic member is formed on the outer stopper to maintain the state in which the outer stopper is moved upwards relative to the inner stopper, the first stopper of the inner stopper and the second stopper of the outer stopper are kept separated from each other. Even if the external stopper is turned, the rotational force is not transmitted to the inner stopper, so the child protection performance is excellent.
