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 spout stopper to make it easier to pour out the liquid, and there is a spout fitting with an external thread attached to the spout hole of the liquid container (paper container), and this spout fitting. It consists of an inner plug that is movable up and down inside the container, and a cap that is screwed onto the spout, and when opening the container, the inner plug is pushed in and the film covering the spout hole is torn and opened. During storage, the cap was fitted into a spout (for example, see Japanese Utility Model Publication No. 58-37828).

[Problems to be solved by the invention] However, as mentioned above, with conventional spout stoppers, when opening the cap, the inner stopper must be pushed in with a fingertip to break the film that seals the spout hole. , a considerable amount of force was required to open the package, making it difficult to open the package.

[Means for Solving the Problems] The present invention has been made in consideration of the above-mentioned conventional problems. A pouring spout 2 having a cylindrical portion 20 corresponding to the hole, and an internal thread 41 screwed into the screw 22 provided on the cylindrical portion 20 of the spout 2, and is detachably attached to the spouting device 2. the cap 4 and the cylindrical portion 20 of the spout 2
It consists of an unsealing blade 4 which is provided so as to be movable up and down by being engaged with a vertical groove 21 inside, and has a partition 34 inside to partition a contents flow path and an air flow path,
The opening blade 4 is provided with a column 6 having an external thread 60 in the center, and the cap 4 is provided with a cylinder 5 that hangs down from the center of the top and into which the column 6 is inserted.
A note for a liquid container, characterized in that it has an internal thread 50 which has a larger pitch than the internal thread 41 of the cap 4, is screwed into the external thread 60 of the column 6, and is lowered when the cap 4 rotates upward. The present invention provides a stopper to solve the above-mentioned conventional problems.

[Function] In the present invention, when the cap screwed onto the pouring spout is rotated upward, the cylinder rotates and the column inserted into the cylinder descends, that is, the entire opening blade descends. The film will be torn to open the spout hole.

[Example] Next, the present invention will be described in detail based on an example shown in FIGS. 1 to 3.

1 in the figure is a synthetic resin pouring stopper, and this pouring stopper 1
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.

An opening blade 3 is located at the spout A in the cylindrical portion 20, facing a breakable film b that seals the spout a from inside the container. This opening blade 3 is formed into a cylindrical shape, and a protrusion 31 protruding from the outside of the upper edge of the cylindrical portion 30 movably engages with a vertical groove 21 on the inner surface of the cylindrical portion 20 of the spout 2. An unsealing blade 3 is provided so as to be movable up and down with respect to the pouring spout 2. The unsealing blade 3 has a blade portion 32 that breaks the flume b along its lower edge. In addition, in the opening blade 3, a through hole 33 is provided in the cylindrical portion 30, and a partition 34 is provided to prevent pulsation during pouring, and this partition 34 serves as a flow path for the contents and air. A through hole 33 located close to the partition 34 serves as an air passage, allowing the contents to be poured out smoothly.

A cap 4 is attached to the cylindrical part 20 of the spout tool 2 so as to cover the spout A, and the cap 4 can be removed by screwing into the external thread 22 of the cylindrical part 20 and rotating it. It can be installed. Further, a cylinder 5 hangs down from the center of the top 40 of the cap 4, and an internal thread 50 having a larger pitch than the internal thread 41 of the cap 4 is provided inside the cylinder 5. Then, the opening blade 3 is attached to this cylindrical body 5.
A column 6 is inserted into the center of the column.
The columnar body 6 has an external thread 60 that is screwed into the cylinder body 5, and when the opening blade 3 is not rotated, the cap 4 is closed.
When the column 6 is rotated upward, the column 6 is rotated by the rotation of the cylinder 5.
The opening blade 3 is provided so that it descends, that is, the opening blade 3 descends.

In the spout tap described above, in order to unseal the spout hole a, it is sufficient to rotate the cap 4 upward, and the column body 6 is pushed down toward the film b side by the rotating cylinder 5 (at this time, the projection 31 is the vertical groove 2 of the cylindrical part 20
1 and does not rotate, but is guided downward by this vertical groove 21), the film b is torn and the spout hole a is easily opened. Thereafter, the cap 4 covers the spout A in an openable and closable manner, and by removing the cap 4, the contents can be poured out from the spout A.

In addition, in order to easily attach the spout tap,
When rotating the cap and attaching it to the spout, the opening blade may be inserted from above and positioned within the cylindrical portion in advance.

[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, and a cap 4 which is removably attached to the spout 2 and has an internal thread 41 that screws into the outer thread 22 provided on the cylindrical portion 20 of the spout 2. and the cylindrical portion 20 of the spout tool 2
It consists of an unsealing blade 4 which is provided so as to be movable up and down by being engaged with a vertical groove 21 inside, and has a partition 34 inside to partition a contents flow path and an air flow path,
The opening blade 4 is provided with a column 6 having an external thread 60 in the center, and the cap 4 is provided with a cylinder 5 that hangs down from the center of the top and into which the column 6 is inserted.
Inside, there is an internal thread 50 which has a larger pitch than the internal thread 41 of the cap 4, is screwed into the external thread 60 of the column 6, and is lowered when the cap 4 rotates upward. ,
The opening blade can be lowered to tear the film and open the spout hole, making the opening operation easy and requires little force, and it is hygienic as it does not come into contact with the film.It has excellent practical effects. It is something to play.
