〔Example〕

 Next, the present invention will be described in detail based on embodiments.

1 is a synthetic resin spout according to the present invention.
It is composed of an opening blade 3 and a cap 4, and is fixed to the spout 2 by means of ultrasonic welding or the like around a pouring hole a located on the upper slope of the Gobel top type container 5, for example. The spout 2 has a flange 20 and a cylindrical portion 21.
Connects to the flange 20 to form a spout A corresponding to the spout hole a of the container 5, and a protrusion 22 having a wedge-shaped horizontal cross section is provided in the vertical direction of the inner wall portion. The ridge 22 allows the opening blade 3 to move up and down, allows the opening blade 3 to rotate from the thin-walled portion side to the thick-walled portion side, and prevents rotation from the thick-walled portion side to the thin-walled portion side. ing. At least two pieces are required to stably prevent the rotation of the opening blade 3, and in this case, eight pieces are provided at equal intervals. Protrusions 23 and 24 for preventing the opening blade 3 from falling off are provided in the circumferential direction of the inner wall portion so as to intersect with both ends of the protrusion 22 to allow the opening blade 3 to rotate in the horizontal direction. The upper protrusion 23 is provided discontinuously so that the opening blade 3 can be easily fitted therein. An outer screw 25 is provided on the outer wall portion so that the cap 4 can be screwed. Cylindrical part of spout 2
The opening blade 3 to be inserted into the spout A formed by 21 is provided with a blade portion 30 that breaks the film 6 that seals the spout hole a at the lower edge of the substantially cylindrical body portion and can slide up and down. The projection 31 provided on the upper edge of the outer wall portion is rotatably engaged with the circumferential projections 23 and 24 of the spout to rotate in the horizontal direction to prevent the projection from falling out, and the projection 31 in the vertical direction. It also works to prevent free rotation in the spout A by engaging with the strip 22. Stable opening blade 3
In order to engage with the ridge, at least two pieces are required, and in this case, four pieces are provided at equal intervals. The inner wall portion is further provided with a pair of guides 32 inclined from the upper edge toward the lower edge.

A cylindrical body 41 is provided on the back surface of the top portion 40 of the cap 4, and the cylindrical body 41
A guide 42 that is inclined from the side of the point 40 toward the lower edge is provided on the outer wall of the. The guide 42 is provided so that it can be slidably contacted with the guide 32 of the unsealing blade 3, and when the cap 4 is rotated upward in the direction of the arrow, the cylindrical body 41 is rotated and the cylindrical body 41 is rotated. The slope of the guide 43 provided is in sliding contact with the guide 32 of the unsealing blade 3, but since the projection 31 of the unsealing blade 3 is engaged with the ridge 22 of the spout 2, the rotation of the unsealing blade 3 is stopped. Below,
That is, the structure is such that it descends in the direction of the film 6 that seals the pouring hole a of the container 5.

In the spout 1 having the above structure, the spout 2 is fixed to the spout hole a of the container 5 by the flange 20, and the opening blade 3 is formed on the discontinuous projection 23 provided in the circumferential direction of the spout 2. It is locked and inserted into the spout A of the spout 2.

By rotating the cap 4 downward in the direction opposite to the arrow in FIG. 1, the cap 4 is screwed onto the cylindrical portion 21 of the spout 2. At this time, the projection 31 of the opening blade 3 is pushed to the position of the ridge 22 provided in the vertical direction of the spout 2. When the cap 4 is rotated upward in the direction of the arrow in this state, the guide 42 slantingly provided on the outer wall portion of the tubular body 41 is in sliding contact with the guide 32 of the opening blade 3, so that the opening blade 3 is rotated with the rotation of the cap 4. Also begins to rotate. However, the opening blade 3 is prevented from rotating by the projections 31 engaging the protrusions 22 provided in the vertical direction of the spout 2, so that the guides 32 and 42 slidably slidably contact the cylindrical body.
The rotational force of 41 acts as a force for lowering the opening blade 3. Therefore, by rotating the cap 4 upward in the direction of the arrow, the opening blade 3 is pushed down in the direction of the film 6 that seals the pouring hole a of the container 5, and the film 6 is pierced and opened. When the opening blade 3 descends, it passes over the ridge 23, but the ridge 23 is discontinuously provided, so the cap 4
The power to turn may be small. When the cap 4 is spliced as it is and rotated in the direction of the arrow, it disengages from the outer screw 25 of the spout 2, so that the spout A is opened and the contents can be spouted. Since the opening blade 3 that has descended at a glance is not engaged with the cap 4, it does not move vertically even if the cap 4 is rotated in any direction. Further, since the projection 31 of the opening blade 3 is located between the protrusions 23 and 24 for preventing the falling off, it does not fall into the container 5 or come out of the container.

The protrusion 23 for preventing the opening blade 3 from falling off, which is provided on the inner wall of the spout 2, may be continuously provided if it is made slightly thinner than the protrusion 24 to facilitate fitting. The spout 2 is fixed to the spout hole a of the container 5 from the outside, and the cylindrical portion 21 is inserted from the inside of the container 5.
It is also possible to take out to the outside and fix it to the inside of the container 5 on the upper surface of the flange 20. The spout 2 and the cap 4 may be attached in a rotatable state in addition to the screwing method shown in this embodiment. The opening blade 3 may be provided with a through hole in the substantially cylindrical body to improve the circulation of the contents.

[Effect of device]

As described above, in the liquid container pouring stopper according to the present invention, the opening blade is locked to the ridge provided on the inner wall portion of the spout, inserted into the spout, and the cap is rotated. Since it is possible to break the film by lowering the opening blade in the direction of the film that seals the pouring hole of the container, there is no risk of damaging the sealing film while inserting the opening blade, and it is suitable for use. It is extremely easy to open the container, and the spout
It has excellent practical effects such as being hygienic without touching the opening blade and the sealing film.
