Abstract

PROBLEM TO BE SOLVED: To provide a filling port for a bag-in-box, which prevents erroneous disengagement during use in spite of adoption of a simplified structure. SOLUTION: A liquid passage hole is formed of plural leg parts 33 installed so as to extend protrusively from the lower part of the inner wall of a spout 10 in the upward direction of the inside, and a check valve 30, which is fitted for fixation to the spout 10, is constitutionally provided with a seating part 34 for making the section of the hole 23 of a female connector 20 blocked from below in the upper parts of the leg parts 33. The spout 10 without the check valve 30 can be molded by means of a mold dispensing with forced unmolding during molding, and a solid undercut can be formed in an annular protrusion 17 for fitting in the upper part of the inner wall of a cylindrical body 11, for the purpose of enabling an increase in force for being fitted into the female connector 20. The spout 10 can be molded from a rigid resin, in order to further increase the force for fitting the spout 10 into the female connector 20.

The filling port described in the prior art uses a spout integrally formed with a valve. Therefore, the filling port can be provided with a check valve function only by combining the two parts of the spout and the female connector, and there is an advantage that the structure is simple and the cost is low. However, the spout has a problem that it is difficult to form a sufficient undercut in the annular convex portion for fitting with the female connector because the valve is integrally formed. That is, since the mold is removed from the opening of the spout at the time of molding, if the undercut is formed, the undercut is forcibly removed, and an undercut having a sufficient fitting force cannot be formed. In addition, since the spout is made of a soft resin in order to make the valve elastic, the fitting force with the female connector is also weak from this point. In particular, when heat is applied in summer or the like, the resin is further softened, and the fitting force with the female connector is reduced.
In addition, the content liquid is filled into the inner bag from the spout, and at the time of this filling, the content liquid adheres to the inner wall surface of the spout, which promotes slipping, further weakening the fitting force with the female connector. I will. As described above, when the fitting force between the spout and the female connector is weak, there is a possibility that the spout will accidentally come off during use and overflow with the content liquid.

As described above, the spout 10 and the check valve 30
The spout 10 is a separate body, and the inside of the spout 10 has a completely empty shape, so that the spout 10 can be molded by a mold that does not need to be forcibly removed at the time of molding. Therefore, the cylindrical body 11
A reliable undercut can be formed in the annular convex portion 17 on the upper part of the inner wall of the inner connector, and the fitting force with the female connector 20 increases. Further, since the valve which should be made of a soft resin is not integrated and only the spout 10 needs to be formed, it can be formed of a hard resin, and can be fitted to the female connector 20 formed of the same hard resin. The resultant force becomes stronger.

When using the filling port having the above configuration,
The check valve 30 is fitted and fixed to the spout 10 in advance. After filling the inner bag of the bag-in-box with a predetermined content liquid from the spout 10 at the filling factory, the spout 1
The female connector 20 is fitted and fixed at 0. Then, in order to pour out the content liquid from the bag-in-box filled in this way, the spout 10 is fixed to the hole formed in the cardboard box, and the male connector is pushed into the female connector 20 and fixed. By pushing in this way, the distal end portion of the male connector breaks through the thin film 22 of the female connector 20 and the seat portion 34 of the check valve 30 is bent downward. In this state, the content liquid passes through the spout 10,
It is taken out of the male connector through the liquid passage hole 23 of the female connector 20. Since the spout 10 and the female connector 20 are securely fitted and fixed, the female connector 20 does not come off from the spout 10 due to the operation during use.

According to the present invention, there is provided a bag-in-box filling port comprising a cylindrical spout attached to a hole of an inner bag by a flange at a lower end, and a female connector fitted and fixed to an opening of the spout from above. The female connector has a cylindrical inner surface for inserting a male connector and a liquid passage hole provided with a pierceable thin film at a bottom portion connected to the male connector, and a check valve is fitted into a lower portion of the inner wall of the spout. The check valve is fixed, and the check valve has a liquid passage hole formed by a plurality of legs extending convexly inward from the lower portion of the inner wall of the spout and a female hole is formed on the upper portion of the legs. By adopting a configuration that has a seating part to block the liquid passage hole part of the connector from below, the spout without a check valve can be molded with a mold that does not need to be forcibly removed at the time of molding. Therefore, a reliable undercut can be formed in the annular convex portion for fitting at the upper part of the inner wall of the tubular body, and the fitting force with the female connector is increased, and furthermore, it is made of another member. The spout and the check valve can be molded using a flexible resin and a hard resin, respectively.As a result, the mating force between the spout and the female connector can be increased. Can be prevented from coming off.
