2. Description of the Related Art As containers for storing cosmetics, medicines and the like, those using spring stoppers which are opened only when an external force is applied to the container opening are widely used. However, in the case of cosmetics, customers often open the container on their own and try the contents, and if the container is returned to its original state after opening, it will be almost the same as the original sealed state. Even if the merchandise value is significantly reduced due to a decrease or deterioration of the merchandise, it cannot be distinguished from other unopened goods at a glance. As a result, troubles are likely to occur, and it is not possible to prevent fraud and troubles caused by opening.

For this reason, various measures have been taken to prevent the spring plug from being returned to its original state once it has been opened. For example, a projecting member having a spring member provided in a middle plug fitted to a container mouth is provided. Projecting the piece onto the inner plug, projecting an engaging piece on the outer peripheral surface of the projecting piece,
Engage the engagement projection provided on the inner peripheral surface of the cylindrical wall of the sealing cap,
Once the sealing cap is removed and opened, the sealing cap cannot be reattached (Japanese Utility Model Laid-Open No. 62-165253), or the projecting portion of the spring plug inside the inner plug fitted into the container mouth is removed. An annular ridge is formed on the inner plug so as to closely engage with the upper surface of the inner plug, and when the annular ridge is pushed into the inner plug and opened once, the spring plug is again closed. It has been practiced to prevent an annular ridge formed on the protrusion from being pulled out onto the inner plug (Japanese Utility Model Laid-Open No. 63-52763) to prevent unauthorized use.

[0004]

However, once the sealing cap is removed and opened once, the sealing cap cannot be reattached in the conventional pouring cap device, so that the sealing cap is relatively large to facilitate removal. Therefore, it is not possible to seal with the lid at the top end of the inner plug, and if liquid leaks from the spout of the inner plug, a large amount of There is a drawback that cosmetics, chemicals, and the like accumulate. In addition, if the sealing cap is made small to seal the lid with the top end of the inner plug, it is difficult to operate the sealing cap with a finger.

[0005] Further, once opened, the conventional tamper-resistant plug, in which the annular ridge formed at the projecting portion of the spring plug cannot be pulled out onto the inner plug again,
Although the seal is formed by the annular ridge formed on the protruding part of the pushed-in spring plug and the lower peripheral surface of the inner plug, the seal position is changed before and after being pushed. The sealing effect between the inner plug and the spring plug is poor,
When used repeatedly, there is a disadvantage that the seal portion is displaced and liquid leakage easily occurs.

[0006]

The present invention has been made as a result of various studies in order to eliminate the drawbacks of the conventional unauthorized use prevention coating plug. The valve seat narrows upward on the inner peripheral surface of the upper end portion. An inner plug that forms a surface and is fitted to the container mouth, and a cylindrical wall having a plurality of spring strips erected on the inner peripheral wall at the lower end of the inner plug are engaged and fixed, and are integrally connected to the upper end of each spring strip. A spring plug in which a closed annular valve is liquid-tightly pressed against a valve seat surface narrowing above the inner plug, and an annular ridge that closely engages the mouth of the inner plug are provided on the peripheral surface so as to protrude into the inner stopper opening. When the inner plug is fitted into the inner plug, a projection that comes into contact with the annular valve of the spring plug constitutes a coating plug for preventing unauthorized use, and the valve seat surface of the inner plug and the annular valve of the spring plug provide a sufficient sealing effect. At the top end of the inner plug so that it can be sealed with the lid. Simply press down the protrusion protruding from the part into the inner plug, so that the annular ridge provided on the peripheral surface of the protrusion enters the inner plug and is opened, and at the same time, once opened, returns to the original state In this way, unauthorized use can be effectively prevented by a simple operation with a sufficient sealing effect.
