DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to sake, fruit juice beverages,
The present invention relates to a spout protruding from the top of a liquid paper container used for seasonings, oils, detergents, and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, for example, a liquid paper container (20) has a square pillar-shaped body, and its gable roof-shaped top inclined plate (21) is easy to pour out. Therefore, the one with a spout was widely used. This plug is
The cap body is provided with a cap attached to the plug body, and the plug body is usually provided with a sealing plate for imparting an unopened property below the inner side of the peripheral wall. An annular thin fragile line was formed in which the support pillar protruded inward. And when you pour out the contents,
Remove the cap, pull the tension ring contained in the peripheral wall of the plug body upward with your finger, tear the annular thin weak line formed on the sealing plate, remove the sealing plate and open the container Then, the contents were poured out from the opening at the tip of the peripheral wall by inclining the container.

[0003]

However, the recent changes in lifestyle have led to an increase in the size of the liquid paper container, and as a result, a large, wide-mouth plug has been used. However, wide-mouth plugs have a large flow rate at the time of pouring, and it is difficult to determine the outflow direction.Therefore, when the mouth of the container to be transferred is small, there is a risk of spilling the contents out of the container. .

The present invention solves the above-mentioned problem of the conventional plug, and when pouring the contents into another container,
An object of the present invention is to provide a spout which is used for a large-sized liquid paper container which is easy to pour the contents and which is compact at the time of distribution, in order to rectify the outflow amount of the contents and to determine the pouring direction.

[0005]

That is, the first aspect of the present invention is as follows.
In the invention , a fitting portion is provided on the lower inner side of the plug body so that the rectifying portion is provided.
The plug is fitted with a material and projects downward from the top of the liquid paper container.
Semi-annular portion of double peripheral wall forming a fitting groove to be inserted from the side
And a beak-shaped pouring projecting outward at the center of this semi-annular part
A separate pouring member attached, consisting of an upper plate with a part,
A plug which is detachably fitted to one side of an upper end portion of a peripheral wall of the plug main body .

In a second aspect of the present invention, there is provided a closing plate which can be opened by a thin-walled weak line below the peripheral wall of the plug body, and a fitting portion is provided below the closing plate to form a rectifying member.
When the contents are poured out, a lower end is attached to the upper end of the peripheral wall of the plug main body.
Semi-annular portion of double peripheral wall forming a fitting groove to be inserted from the side
And a beak-shaped pouring projecting outward at the center of this semi-annular part
A separate pouring member attached, consisting of an upper plate with a part,
A plug which is removably fitted to one side of an upper end portion of a peripheral wall of the plug body .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 2, a plug (10) of the present invention comprises a plug body (100) and a rectifying member (200).
And a pouring member (300) and a cap (400). These members are made of a thermoplastic resin such as polyethylene or polypropylene by an injection molding method. The plug of the present invention has a straightening member fitted below the inside of the plug main body, and the pouring member is accommodated inside the top of the plug main body or attached to a container, and the plug main body is used at the time of use. With a cap on it. The plug (10) is attached to the liquid paper container by, for example, as shown in FIG. 5, the lower part of the plug body is ultrasonically sealed to the top inclined plate (21) of the liquid paper container (20). It is obtained by heat fusion by a method or the like.

The plug body (100) usually has, as shown, for example, in FIG. 2, a sealing plate (120) for imparting an unopened property to the inside lower part of the peripheral wall (110), and has a circular thin weak line. (121) formed on the support plate (1) having a tension ring (123) at its tip.
Reference numeral 22) denotes a member which is vertically provided inside the thin weak line (121). A fitting portion (111) for fitting the rectifying member (200) is provided on the lower inner side of the closing plate of the plug body.

The rectifying member (200) is, for example, as shown in FIG.
As shown in (a) to (c), a fitting part (211) for fitting to the plug body is provided on the outer periphery of the annular frame part (210), and the inner part tapers from the inner periphery toward the center of the pouring hole (230). Rectifier plate (22
0). This current plate is usually
Although it is triangular, the shape, size, and number are designed according to the intended use when planning the product.

Further, the pouring member (300) is shown in FIG.
As shown in (c), the double peripheral wall (3) forming a fitting groove (313) to be fitted from below into the upper end of the peripheral wall of the plug body.
11 and 312), and a beak-shaped pouring portion (320) projecting outward from the center of the semi-annular portion in a continuous manner with the upper plate (314) of the semi-annular portion. is there.

When the contents are poured out for the first time, for example, in the plug (10) of the present invention shown in FIG. 2, first, the cap (400) is removed, and then the peripheral wall of the plug body (100). After taking out the pouring member (300) housed in the (110), the pulling ring (123) in the peripheral wall is pulled upward by a finger to the front, and the sealing plate (1) is pulled out.
20) Torn off the annular thin line of weakness (121) formed, remove the sealing plate, open the container, and then
As shown in FIG. 1, the peripheral wall (11) of the plug body (100)
0) A spouting member (300) is attached to one side of the upper end by inserting and inserting the beak-shaped spouting portion outward, and the container is inclined to pour the contents from the beak-shaped spouting portion of the spouting member. It will be issued.

In the spout of the present invention, when the contents are poured into another container, a rectifying member is fitted to the lower inner side of the spout body, and a beak-shaped spout is provided at one upper end of the peripheral wall. Since the protruding pouring member is inserted, the contents that flow out to the mouth due to the inclination of the container are first prevented from flowing out by the plurality of rectifying plates that partially cover the outflow holes of the rectifying member. The outflow is restricted and rectification occurs. Next, the rectified contents are
The liquid is poured from the dispensing member to another container through the peripheral wall, and the direction of dispensing is determined by the tapered beak-shaped dispensing portion of the dispensing member. As a result, even if the plug of the present invention is wide-mouthed, the contents can be poured into another container having a relatively narrow mouth without spilling the content out of the container.

In the plug of the present invention, in a plug having a closing plate which can be opened by a thin line of weakness inside a peripheral wall of the plug main body, a flow regulating member is provided below and inside the plug main body during distribution. This is a compact plug that can be fitted and accommodated with a cap by accommodating the pouring member inside the peripheral wall above the sealing plate.

[0014]

When the spout of the present invention is used for a large-sized liquid paper container, when pouring the contents into another container, the outflow amount of the contents is regulated and the pouring direction is determined. Even if the contents are easy to pour and the mouth of another container is small, there is no danger of spilling the contents out of the container. In addition, it is a compact plug that can house the spouting member in the plug body during distribution.
