Description of the Related Art Conventionally, as a container for accommodating a softening agent, a liquid detergent and the like, there is a container made of a synthetic resin which has been formed by a blow molding. The container has a cylindrical mounting portion that allows a measuring cap or a normal cap to be attached and detached by screwing,
A spout with a large beak-like spout that is located inside the mounting section and rises up is attached, allowing the contents to be metered and spouted while preventing liquid dripping. It was designed so that the liquid drainage at the time of discharge was also good.

うになってきている。In recent years, it has been desired to use a paper container mainly made of paper instead of a synthetic resin container in consideration of environmental destruction due to wastes. I have.

予め閉鎖しておく必要が生じる。[0004] Therefore, it is conceivable to form the plug used in the liquid paper container into the shape of the plug having the above-mentioned beak-shaped pouring portion. However, in the case of a spout in which the above-mentioned pouring part is opened in advance and becomes a beak-shaped pouring part, there is a possibility that the contents may leak due to a fall or the like at the product distribution stage and the liquid amount may decrease. It is thought that the blow bottle has a container shape,
Stability was obtained by adjusting the position of the plug and the material used. On the other hand, when a spout with a beak-shaped spout is used for a liquid paper container, the spout is closed in advance in consideration of, for example, when it falls down, since the shape of the container becomes substantially prismatic. Need to be kept.

は、引き代が長くなって切断する可能性が生じてくる。For this reason, as shown in Japanese Utility Model Publication No. 40-29660, the opening in the pouring portion is integrally closed with a closing plate using a half cut (thin portion). A pull-open structure of a type in which the closing plate is pulled up from the pull-up opening when necessary can be used. However, in the conventional pull-open structure, since the flat plate closing plate formed on the inner bottom plate of the pouring section is to be pulled up in a direction perpendicular to the closing plate, the closing is not performed. It is difficult to remove the plate portion, and in the case of the above-described plug having a beak-shaped spouting portion with a large protruding height, the pulling margin becomes long and there is a possibility of cutting.

ピンホールが発生する可能性がある。Further, in the spout used for the liquid paper container containing the above-mentioned softening agent and liquid detergent, the opening of the spout portion needs to be enlarged because the amount of the spout from the container is relatively large. In the case of the above-mentioned plug of the pull-open structure, it is necessary to locate the thin portion on the outer side (enlarge the closing plate so that a wide opening can be obtained when the closing plate is removed). . However, when the thin portion is located on the outer side, a pinhole may be generated in the thin portion by the action of the ultrasonic welder used when attaching the plug to the container.

うにすることを目的とする。In view of the above circumstances, the present invention makes it possible to easily remove a closing plate portion for closing a spout portion when necessary from a plug of a pull-open structure attached to a liquid paper container. The purpose is to increase the opening of the spouting section while setting the thin-walled section at a position that is hardly affected by the ultrasonic welder. Attach a spout-shaped spout to the liquid paper container and unopen it. It is an object of the present invention to make it possible to easily pour out the contents during use without leakage.

As shown in the figure, a bottom thin portion 70 formed in a substantially U-shape on a part of the inner bottom plate portion 4 on the container top side, and the bottom thin portion 70
Rising portions 71, 71 along the rising side edges 50 of the to-pour portion 5, respectively, and the rising thin portions 7

て、前記の開口から容器内に戻すことができる。As shown in FIG. 3, in the vicinity of the bottom thin portion 70 of the closing plate portion 6, a pull-up portion 8 reinforced by thickening the base end is formed so as to rise upward. By pulling up the pull-in portion 8 first,
The bottom thin portion 70 is torn and the bottom protruding end of the closing plate portion 6 provided with the pull-off portion 8 is lifted up, and then, as shown in the figure, the rising thin portion 71 arranged to open in an inverted C shape. , And the slope of the closing plate 6 is pulled up. Then, the top surface of the closing plate portion 6 is pulled up by the tearing of the upper thin portion 72, and by removing the closing plate portion 6, the pouring portion 5 is moved from a part of the inner bottom plate portion to the pouring portion 5 as shown in FIG. An opening C that is largely open toward the protruding tip edge 51 is obtained. The contents can be poured out by opening the pouring portion as described above, and the closing plate portion is cut off at the protruding tip edge of the pouring portion 5 projecting like a beak. Therefore, the liquid shortage at the time of pouring is also improved. In addition, since a part of the opening C extends to the inner bottom plate portion, the measuring cap used for the measurement is attached back to the spout, and the liquid that has dropped from the measuring cap and dropped on the inner bottom plate portion is transferred to the container. Can be returned from the opening into the container by slightly inclining it.

However, it may be a shape having a ring as shown in FIG. It is not something to be done. Further, in the embodiment, the cap mounting portion is illustrated as an internal screw type when mounting the cap. However, the cap mounting portion may be an external screw type, or a normal mounting without using a screw structure. It is not limited.

The stopper for a liquid paper container is made of a synthetic resin having an annular cap attachment portion to which a cap is attached, and a flange portion attached to and fixed to the liquid paper container along the periphery of the attachment portion. A beak-shaped spouting portion raised from an inner bottom plate portion along the inner periphery of the mounting portion, and a projecting tip of the spouting portion through a rising side edge of the spouting portion so as to partially overlap the inner bottom plate portion. A closing plate portion provided integrally with the pouring portion via a breakable thin portion along the edge and covering an opening of the pouring portion, and a closing portion close to the inner bottom plate side thin portion of the closing plate portion; And a pull-up portion raised from the plate portion.

る。As described above, since the thin portion extends from a part of the inner bottom plate portion to the tip of the pouring portion via the side surface of the pouring portion, the pull-up portion is pulled up, and the thin portion on the inner bottom plate portion side is torn. Thereafter, the angle between the pulling-up direction of the pull-in portion and the thin portion on the side of the spout becomes small, so that the thin portion (side edge of the spout) is torn by a small force, and the momentum of the momentum is increased. The thin portion of the protruding front edge of the spouting portion can be easily cut in the state, and the opening operation of the spouting portion becomes extremely simple.

切れを良好なものとすることができる。In addition, compared to a conventional spout provided with a pull-open structure in the spout, there is no plate-shaped part in the spout,
There is no liquid pool in the spout. Since the closing plate portion is cut and removed from the thin portion along the protruding tip edge of the pouring portion, it is possible to make the liquid at the tip of the pouring portion excellent.

など、実用性に優れた効果を奏するものである。Further, since the thin portion is arranged from a part of the inner bottom plate portion to the tip of the pouring portion through the side surface of the pouring portion and is separated from the flange portion, the thin portion is superfluous when the plug is attached. This is an effect that is excellent in practicality, such as being less susceptible to the sonic welder and not producing pinholes.
