Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a spout plug that is attached to the mouth of a container such as a can or a synthetic resin container for storing liquid or the like.

``Prior Art'' Conventionally, this type of spout plug has been fitted and fixed in a sealed state to a spout plug mounting portion formed on a container, or fixed in a sealed state by caulking using a ring. The spout body is molded from a soft synthetic resin material, and the spout body is molded integrally with the spout body, and when closed, the half cross-sectional shape is bent into a roughly U-shape and stored inside, and when opened. It consisted of a spout that was pulled out to serve as a spout, and a cap that was removably attached to the tip of the spout.

``Problems to be solved by the present invention'' Conventional spout plugs can be damaged due to the pressure inside the container increasing due to temperature changes, or due to shock during transportation, etc. This has disadvantages in that the cap floats upward, it is difficult to detect that the cap has been opened or closed illicitly, and there is a risk that the contents may be refilled.

In view of the above-mentioned drawbacks of the conventional spout, the present invention has been developed to prevent the spout and cap from being removed even if the internal pressure of the container increases or a pushing force is applied to the spout and cap housed in the spout stopper body due to an impact or the like. To provide a spout stopper that can reliably prevent the cap from floating up, easily identify when the cap is opened, and prevent unauthorized opening.

``Means for Solving the Problems'' The present invention consists of a spout plug body molded from a soft synthetic resin material in which a mounting portion is formed to be attached to the spout plug mounting portion of a container, and a spout plug body that is molded integrally with the spout plug body, and when closed. It is equipped with a spout which is bent so that its half cross-sectional shape has a substantially U-shape and is housed inside and is pulled out to serve as a pouring spout when the package is opened, and a cap having a handle that is removably attached to the tip of the spout. In the spout stopper, it is possible to prevent the spout housed in the spout stopper main body and the cap having a handle from floating upward due to the internal pressure of the container between the attachment part of the spout stopper main body and the top surface of the cap. The spout plug is composed of a protector that is adhered or welded to the attachment part of the spout plug main body and/or the top surface of the cap, and once removed, traces of the protector remain and it is visible that the seal has been opened.

``Function'' Even if the spout stopper configured as described above has an effect of pushing up the cap of the spout stopper and protruding the spout when the internal pressure of the container becomes high, this can be prevented by the protector.

Additionally, once the protector is removed, traces remain and it can be visually determined that the protector has been opened.
