Field of the Invention The present invention relates to a spout for a liquid filling bag made of a synthetic resin soft film such as an inner bag for a bag-in-box. More specifically, the present invention relates to a spout plug with good drainage when pouring a liquid filled in a liquid filling bag.

Description of the Related Art The spout of a liquid filling bag made of a synthetic film made of a synthetic resin such as an inner bag for a bag-in-box is formed by making a hole in the film of the bag body and attaching the spout (A) to the film by a joint seal. A spout plug (B) attached to the upper end of the spout by fitting, and an overcap (C) further fitted to the upper end of the spout by fitting. I have. (Refer to FIG. 1) Then, in order to pour out the liquid from the liquid filling bag, first, the overcap is removed, and the liquid filling bag is tilted to pour the liquid from the opening end of the spout plug.

Sometimes. This tendency is particularly remarkable in the case of a liquid having a high viscosity such as oils. The outflow of this liquid is difficult to stop,
The phenomenon of dropping in the form of a thread or a drop is called poor liquid drainage.

で、更なる改良の必要があった。[0004] Poor drainage of the liquid from the spout not only increases the working time for pouring out the filled liquid from the liquid filling bag, but also stains the periphery of the spout and around the work place.
Therefore, an extraction port with good drainage is desired. Conventionally, various methods have been studied for improving the liquid drainage at the spout. For example, Japanese Patent Laid-Open Publication No. Hei 10-45156 describes improvement of drainage of a spout.
That is, a method is disclosed in which the upper end of the pouring tube portion of the pouring port plug is opened outwardly while being curved. However, even the above method has not yet exhibited sufficient liquid shortage, and in particular, in the case of a liquid having a high viscosity such as oils, the liquid shortage has been insufficient, and further improvement has been required.

口栓を油類用に使用する。According to the present invention, the following means are taken to solve the above-mentioned problems. That is, the opening end surface is a ring shape having a flat surface, and the outer peripheral end portion of the ring shape has an acute angle. Preferably, the width of the ring is 1 to 5 mm. More preferably, the angle of the outer peripheral end of the ring is 10 to 60 degrees. In addition, the above-mentioned extraction plug is used for oils.

Regarding the flat state of the ring-shaped surface at the opening end surface, since the spout plug of the present invention is made of synthetic resin, specifically by injection molding, it can be suitably used as it is if it is molded in a flat state. can do. Further, the inner diameter of the ring at the opening end surface is not particularly limited, but is appropriately determined depending on the size of the liquid filling bag and the type of contents. Generally, an inner diameter of 20 to 25 m
m are preferably used.

悪くなる。Further, the ring-shaped width of the opening end surface is preferably 1 to 5 mm. When the width of the ring shape is less than 1 mm, liquid shortage, particularly liquid with high viscosity such as oils, is poor. On the other hand, if the width of the ring exceeds 5 mm, not only the outer diameter of the spout becomes large, but also the amount of liquid adhering to the ring-shaped surface at the front end of the opening increases, and the drainage becomes poor.

In addition, the angle at which the ring-shaped outer peripheral end of the opening distal end surface is acute is defined as the angle at which the ring-shaped surface of the opening distal end and the lower surface of the ring intersect at the ring-shaped outer peripheral end. It means there is. The angle of the ring-shaped outer peripheral end is preferably 10 to 60 degrees. If the angle of the outer peripheral end of the ring is less than 10 degrees, the strength of the outer peripheral end of the ring becomes weak, and it becomes difficult to stably extract the liquid. On the other hand, if the angle of the outer peripheral end of the ring shape exceeds 60 degrees, liquid shortage, especially liquid with high viscosity such as oils, will deteriorate.

It is preferable that the spout protrudes 1 mm or more from the outer peripheral surface of the pouring cylinder. When the protrusion of the ring-shaped outer peripheral end is less than 1 mm from the outer peripheral surface of the pouring tube portion, the liquid drainage effect,
In particular, in the case of a highly viscous liquid such as oils, the drainage effect may be reduced. Note that the upper limit of the length of the ring-shaped outer peripheral end protruding from the outer peripheral surface of the pouring tube is limited by the width of the ring at the opening front end surface and the thickness of the pouring tube.

周囲や作業周辺を汚すようなこともなかった。Example 1 A spout, a spout plug and an overcap made of polyethylene were attached to a liquid filling bag made of a polyethylene film to form a spout. At that time, the opening tip of the used outlet plug had the shape shown in FIG. The ring shape of the opening tip surface is width (w)
Was 2.5 mm, the surface was flat, and the acute angle (α) of the outer peripheral end of the ring was 20 degrees. The obtained liquid filling bag was filled with salad oil, and the state of the liquid in the spout stopper was checked. As a result, it was found that the liquid was satisfactorily drained without stringing or dropping of drops, so that the pouring operation could be performed in a short time, and the periphery of the spout and the periphery of the work were not stained.

A liquid filling bag having a spout was obtained. The obtained liquid filling bag was filled with salad oil, and the outflow stopper was checked for liquid shortage in the same manner as in Example 1. As a result, the liquid drainage was poor, and the droplets dropped forever, which required a long time for the pouring operation, and further, the surroundings of the spout and the working area were soiled.
