2. Description of the Related Art Generally, the above-mentioned opening stopper is attached to a container such as a plastic bottle or a tare made of polyethylene or the like. A separating piece is provided on this type of opening stopper so that once the stopper is opened, the opening can be easily visually checked. That is, the opening stopper usually includes a main body attached to the housing body side and a stopper body screwed into the main body, and the separation piece is provided on the stopper body, and when the opening is opened, the main body is separated from the main body. It is configured to engage and separate from the plug. Therefore, once the stopper is opened, the separation piece is cut and separated, so that it can be easily visually checked whether or not the stopper has been opened.

[0010] A ring-shaped separating piece 5 is connected to the plug 2 at a constant interval via a connecting portion 3 in a lower region of the outer peripheral surface thereof. There is no particular limitation on the manner in which the separation pieces 5 are connected, but in the present embodiment, the separation pieces 5 are connected to the plug 2 by four connection portions 3 at 90-degree intervals. . When the stopper 2 is twisted in the opening direction at the time of opening the separating piece 5, the connecting portion 3 is cut off by a protrusion (described later) formed on the main body 10 and separated from the stopper 2. In this case, the separated pieces 5 are separated from the main body 10.
It is preferable to form an inclined portion 5a that is inclined outward and upward on the separation piece 5 so as not to be separated from the partition piece 5 so that the whole is spread upward. That is, by expanding the upper side in this way, it is possible to make it difficult for the separation piece to come off.

The engaging portion 15 of the main body 10 has a cutting means for cutting the connecting portion 3 of the screwed plug 2 at the time of first opening. The cutting means of the present embodiment is formed on the low surface portion 16 and is provided at predetermined positions on the circumference at predetermined positions on the circumference at positions where the connecting portion 3 of the screwed plug 2 can be cut. (9 in the embodiment). These projections 17 have a shape that rises gently in the screwing direction so that the connecting portion 3 is not cut when the plug 2 is first screwed in.
Then, when the plug 2 is first opened, the connecting portion 3 is cut by the cut surface 17a of the projection 17 which rises gently.

This cutting means can be variously deformed as long as the connecting portion 3 of the plug 2 can be cut at the time of the first opening, and for example, a frictional force is applied to the separating piece 5 and the friction at the time of the opening is The structure which cuts a connection part by force may be sufficient. This is achieved, for example, by utilizing the elastic deformation of the ring-shaped separating piece 5 itself, when the main body 1 is first screwed.
If the size, shape, and the like of the separation piece 5 and the peripheral wall portion 25 are set so as to be fitted to the portion of the peripheral wall portion 25, frictional force acts when the plug 2 is opened, and connection is established. The part 3 can be cut.

Openings 26 are formed in the peripheral wall 25 at predetermined intervals so that the separation pieces 5 can be easily viewed. Further, the upper end of the peripheral wall 25 is provided with the protrusion 17.
Locking portions 27 projecting toward the center are formed at predetermined intervals so as to lock without separating the separated pieces 5 separated from each other. This locking portion can also be variously deformed, and can be variously deformed so long as the separated piece is not detached. For example, the structure may be integrated with a cutting unit that separates the separation pieces by the frictional force described above.

Next, with reference to FIGS. 4 and 5, the operation of the opening plug 1 configured as described above will be described. The stopper 2 is attached to the mouth 11 of the main body 10 attached to a tare (not shown) while rotating the stopper 2 in the direction of the arrow. At this time, the protrusion 17 formed on the bottom surface 16 of the main body is
The connecting portion 3 of the plug 2 is not cut off by the screw mounting since the plug 2 has a shape that gradually rises in the screwing direction of the plug 2.

When the plug 2 is first twisted in the direction opposite to the direction of the arrow to open it, the connecting portion 3 connecting the plug 2 and the separation piece 5 is formed by the cut surface 17 a of the projection 17. It is cut and the separation piece 5 is separated from the plug 2. Since the separation piece 5 has a shape such that the whole is spread upward by the inclined portion 5a, the locking portion 2 formed on the peripheral wall portion 25 of the main body 10 is formed.
7 and is easily retained in the engaging portion 15. The separation piece 5 is held in the engagement portion 15 irrespective of the subsequent opening / closing operation of the plug 2, and this state can be easily viewed through the opening 26.

As described above, the separating piece 5 that separates from the plug 2 at the time of the first opening is locked in the main body 10 only by the screwing operation of the plug, that is, at the time of the first opening of the plug 2, Since the piece 5 can be configured to be separated from only the plug 2 while being held by the main body 10, the operation when the plug 2 is first assembled to the main body 10 is facilitated. In addition, the separation piece 5
Regardless of the subsequent opening / closing operation of the plug 2, the engaging portion 1
Because it is held in the opening 5, the opened state can be easily visually observed, and the separation piece 5 does not separate from the main body 10.
