Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pouring stopper that is attached to a container containing a liquid.

[Prior Art] Paper containers such as the Goebel top type have been used for the purpose of reducing the manufacturing cost and weight of liquid containers. Some of these paper containers are equipped with a pouring stopper made of synthetic resin so that the liquid can be easily poured out, and a pouring spout having an external thread is attached to the pouring hole of the liquid container (paper container). An inner plug that is movable up and down inside the spout,
It consists of a cap that is screwed onto the spout, and when opening, the inner stopper is pushed in and the film covering the spout hole is torn and opened.When storing, the cap is screwed onto the spout. It was designed to fit into the exit fitting (for example, Utility Model 58-37828)
(see publication).

[Problems to be solved by the invention] However, with conventional spouting stoppers, as mentioned above, the inner plug must be pushed forcefully with a finger to break the film, making it difficult to open the spouting hole. There was also the problem that the cap was easily lost as the spout was repeatedly opened and closed.

[Means for Solving the Problems] The present invention has been made in consideration of the above-mentioned conventional problems. a spout 2 having a cylindrical portion 20 corresponding to the hole; a cylindrical opening blade 4 inserted into the cylindrical portion 20 of the spout 2;
The cylindrical portion 20 is provided with a cover 6 that corresponds to the upper opening of the cylindrical portion 20 and covers the upper opening in an openable and closable manner, and a projection 30 that engages with a groove 21 located over the outer periphery of the cylindrical portion. The opening blade 4 has a protrusion 40 on either the outer surface of the opening blade 4 and the inner surface of the cylindrical portion 20 facing thereto, and the protrusion 40 on the other side. vertical groove 2 that engages to be able to move up and down
The cap 3 is provided with a hanging piece 5 that hangs down along the inner surface of the opening blade 4 and is screwed into an internal thread 41 provided on the opening blade 4. To solve the above-mentioned conventional problems by providing a spouting stopper for a liquid container, characterized in that the opening blade 4 descends while being guided by the hanging piece 5 that rotates when the cap 3 rotates. It is something.

[Function] In the present invention, when the cap is rotated in one direction, the hanging piece screwed into the inner thread of the opening blade rotates, pushing the opening blade downward and allowing it to move up and down into the cylindrical part. The opening blade engages and descends without rotating, that is, it descends while being guided toward the film side,
Then, the unsealing blade tears the film to unseal the spout hole, and the lid body opens and closes the upper opening communicating with the unsealed spout hole.

[Example] Next, the present invention will be described in detail based on an example shown in FIGS. 1 and 2.

In the figure, 1 is a synthetic resin pouring stopper;
is attached, for example, to a pouring hole a located on the upper slope of a Goebelt top type container. As shown in FIG. 1, the spout fitting 2 of the spout stopper 1 is attached to the spout a (by means such as ultrasonic welding) and the spout A corresponding to the spout hole a is attached to the cylindrical portion. It is surrounded by 20.

A cap 3 is attached to the cylindrical portion 20 so as to cover the cylindrical portion 20, and a protrusion 30 protruding from the lower edge of the inner surface of the cap 3 is attached to the cylindrical portion 20.
A cap 3 is rotatably provided and movably engaged in a groove 21 located around the base of the cap 3.
Also, inside the spout A, a cylindrical opening blade 4 is inserted into the spout hole a.
The opening blade 4 is inserted in correspondence with the film b for sealing the opening blade 4, and a protrusion 40 that engages with the vertical groove 22 on the inner surface of the cylindrical part 20 in a vertically movable manner is provided on the upper outer edge of the opening blade 4. The opening blade 4 is provided so that it can descend to the film b side without rotating.

Furthermore, the cap 3 is equipped with a pair of L-shaped hanging pieces 5 that extend over the opening blade 4 and hang down to the spout A. 5 are screwed together, and a hanging piece 5 that rotates and moves as the cap 3 rotates is provided so as to push the opening blade 4 downward.

A lid 6 is connected to the upper outer edge of the cap 3 via a self-hinge hinge portion 31, and the lid 6 opens the upper opening 32 of the cap 3.
In other words, the spout A is provided so as to be able to be opened and closed freely.

In order to open the spout hole a in the spout tap 1 having the above structure, it is sufficient to rotate the cap 3 in one direction, and the rotation of the hanging piece 5 lowers the unsealing blade 4. The film b is torn and the spout hole a is opened with the extremely easy operation of turning the cap 3.
can be opened. After that, the upper opening 32 communicating with the unsealed pouring hole a is covered with a lid 6 so as to be openable and closable.
Re-sealing will be extremely easy.

In the above embodiment, the opening blade is provided with a protrusion, and the cylindrical part is provided with a vertical groove with which the protrusion engages in a vertically movable manner. You can do it like this.

[Effects of the invention] As explained above, according to the invention, the spout plug for a liquid container is attached to the spout hole of a liquid container sealed with a breakable film, and has a spout corresponding to the spout hole. a spout 2 having a cylindrical portion 20; a cylindrical opening blade 4 inserted into the cylindrical portion 20 of the spout 2;
The cylindrical portion 20 is provided with a cover 6 corresponding to the upper opening of the cylindrical portion 20 and covering the upper opening in an openable/closable manner, and with a protrusion 30 that engages with a groove 21 located over the outer periphery of the cylindrical portion. It consists of a cap 3 rotatably attached to the opening blade 4, and has a protrusion 40 on either the outer surface of the opening blade 4 and the inner surface of the cylindrical portion 20 facing thereto, and a protrusion 40 on the other side. The opening blade 4 is provided with a vertical groove 22 that engages with the protrusion 40 in a vertically movable manner so that the opening blade 4 can be lowered. Internal thread provided 4
1, and the opening blade 4 is guided by the hanging piece 5 which rotates when the cap 3 rotates, and the opening blade 4 descends.The opening blade 4 can be opened by simply rotating the cap. After getting down, the spout opening is opened, which is hygienic as there is no need to touch the spout fitting, inner stopper, film, etc. Furthermore, since the lid body and the cap are connected to each other and there is no need to remove the cap when dispensing, the cap can be prevented from being lost, resulting in excellent practical effects.
