The door side upper end locking string 9 is fixed to an upper locking rod 11 provided at the upper end of the concave groove 5.

As shown in FIGS. 1 and 4, the top surface portion 7e also has a cylindrical cargo loading port at the end on the door 4 side which is located to the right of the width direction center line 0 in the drawing. 12 and an air vent 13 are provided respectively, and the cargo inlet 12 and the air vent 13 are secured by ropes or the like when not in use to be closed.

As shown in FIGS. 1, 3 and 4, the bag surface 7d of the bag body 7 is provided with a cargo discharge port 14 in the shape of a rectangular tube. As shown in FIG. 4, it is provided at the lower end of the door surface portion 7d and at a position shifted rightward from the center line 0 in the width direction in the figure. By providing the cargo outlet 14 and the cargo inlet 12 in the same direction from the center line 0 in the width direction, loading and unloading of cargo can be performed with one of the doors 4 that opens and closes in a double door open manner. You can do it.

As shown in FIGS. 1 and 3, on the bottom surface portion 7a of the bag body 7, front side lower end hooks 15 are provided at positions near both ends in the width direction on the front side. Door-side lower end locking strings 16 are provided at the ends on the door 4 side at both ends in the width direction, respectively. As shown in FIG. 2, the front-side lower end hook 15 is detachably engaged with a lower engaging metal fitting 17 provided at the lower end of the rectangular groove 3, and the door The side lower end locking string 16 is fixed to a lower locking bar 18 provided at the lower end of the groove 5.

As shown in FIGS. 1 and 3, the lower end portion of the reinforcing cover 19 is attached to the bottom surface portion 7a at a position where a predetermined dimension is entered from the end portion on the door 4 side to the front side. The reinforcing cover 19 is drawn out to the outside of the door surface portion 7d so as to cover and reinforce the periphery of the cargo discharge port 14.

As shown in FIGS. 3 to 4, the reinforcing cover 19 has an inner cover 19 a having a width about twice that of the cargo outlet 14, and a lateral width slightly larger than the cargo outlet 14. The inner cover 19a has an opening 20 for leading out the cargo discharge port 14 in advance, and the upper edge of the inner cover 19a has an opening 20. An arbitrary number of fixing strings 21 are provided. Further, an arbitrary number of locking strings 22 are provided on the upper edge portion of the outer cover 19b. Then, as shown in FIGS. 1 and 4, these two strings 21 and 22 are separately fixed to the binding string 23 attached to the door surface 7d through the dam plate device 6, whereby the auxiliary cords The upper end of the strong cover 19 can be substantially fixed to the dam plate device 6.

That is, as shown in FIG. 6, the binding cord 23 is wound around the upper end portion of the barrier plate device 6 and pulled out to the outside, and in this state, the binding cords 23 and 22 are individually separated. It is designed to be connected. Since the portion of the door surface portion 7d corresponding to the dam plate device 6 is pressed by the dam plate device 6 with a large force from the cargo, the binding string 23 is in a state as if it was fixed to the dam plate device 6, As a result, the upper end of the reinforcing cover 19 is substantially fixed to the dam plate device 6.

As shown in FIG. 6, the barrier plate device 6 includes, for example, four rail members 24 whose both ends are fitted and locked in the recessed groove 5 (see FIG. 2), and these rail members 24. The barrier plate device 6 is set to a predetermined vertical position by suspending the crosspiece member 24 at the upper end with a hanging string (not shown). It is like this. The crosspiece 24 at the lower end is secured to the lower locking rod 18 shown in FIG. 2 with a rope or the like to prevent the dam plate device 6 from moving up and down when the cargo is discharged.

Next, the operation of this embodiment will be described. In use, first, the container inner bag 1 is mounted in the dry container 2 by using the hooks 8 and 15 at the upper and lower ends on the front side and the locking strings 9 and 16 at the upper and lower ends on the door side. At this time, the cargo loading port 12 and the air vent port 13 are fixed by ropes or the like not shown in the closed state, and the cargo discharge port 14 is also fixed by ropes or the like not shown in the closed state. Moreover, it is drawn out to the outside through the opening 20 of the inner cover 19a and is wound in a spiral shape.

After the container inner bag 1 is installed in the dry container 2, the dam plate device 6 is installed outside the door surface portion 7d of the bag body 7. Then, as shown in FIG. 6, the binding cord 23 is wound around the upper end portion of the barrier plate device 6 and pulled out to the outside, and the binding cord 23 and the fixed cord 21 of the inner cover 19a are first connected, and then the binding cord 23 is connected. The string 23 and the locking string 22 of the outer cover 19b are connected.

Next, the cargo loading port 12 and the air venting port 13 are opened, and the cargo is loaded into the bag body 7 from the cargo loading port 12 using an air lift or the like. Then, when a predetermined amount of cargo is loaded, the cargo loading port 12 and the air vent port 13 are closed again.

By the way, when cargo is loaded in the bag body 7, the door surface portion 7d of the bag body 7 is pressed by the door 4 with a large force. Since the dam plate device 6 is arranged as shown, the door surface portion 7d is pressed against the dam plate device 6 with a large force, and the load is supported by the dam plate device 6. Therefore, there is no problem even if the door 4 is opened.

On the other hand, when discharging the cargo stored in the bag body 7, only the lower door 4 (right door 4) in FIG. 2 is opened. Then, the binding between the locking cord 22 and the binding cord 23 of the outer cover 19b is released to expose the cargo outlet 14, and the rope or the like that secures the cargo outlet 14 is removed to open the cargo outlet 14. To do. Then, the cargo in the bag body 7 is gradually discharged from the cargo discharge port 14.

By the way, since the peripheral portion of the cargo discharge port 14 is not supported by the dam plate device 6 as shown in FIG. 6, a large force is exerted by the discharged cargo. In the embodiment, since this portion is reinforced by the inner cover 19a, there is no problem that the peripheral portion of the cargo discharge port 14 is broken and the cargo is scattered.

That is, as shown in FIG. 6, the lower end portion of the inner cover 19a is fixed to the bottom surface portion 7a of the bag body 7, and the bottom surface portion 7a is pressed against the container bottom wall by the weight of the cargo. Therefore, the lower end of the inner cover 19a is fixed to the bottom wall of the container. On the other hand, the upper end portion of the inner cover 19a is fixed to the portion of the door surface portion 7d corresponding to the dam plate device 6 via the fixing cord 21 and the binding cord 23, and this portion is dammed by a large force from the cargo. Since it is pressed against the device 6 and integrated, the upper end of the inner cover 19a is substantially fixed to the dam plate device 6. In other words, the upper and lower end portions of the inner cover 19a are both fixed to the dry container 2 side and do not follow the movement of the lower end of the door surface portion 7d. Therefore, even if the lower end of the door surface portion 7d tries to bulge outward due to the force from the cargo, it can be sufficiently supported by the inner cover 19a.

The inner cover 19a is reinforced only in the right half portion in FIG. 4, and the left half portion is not reinforced by the inner cover 19a. This is due to the following reasons.

That is, as shown in FIG. 6, the lower end portion of the door surface portion 7d is not supported by the dam plate device 6, so that the door portion 7d bulges outward equally when the cargo is discharged. However, since the left half portion in FIG. 4 is supported by the one door 4 which is not opened, it is not necessary to reinforce by the inner cover 19a. Therefore, in the case of opening the two doors 4 having the double door structure and discharging the cargo from the cargo discharge port 14, it is necessary to reinforce the entire width direction of the lower end of the door surface portion 7d with the inner cover 19a.

Since the inner cover 19a can support a large force from the cargo, it is possible to completely prevent the trouble that the periphery of the cargo discharge port 14 is broken and the cargo is scattered.

In the above embodiment, the case where the binding cord 23 is provided on the door surface portion 7d of the bag body 7 has been described, but the binding cord may be provided on the sheet material 25 of the barrier plate device 6. Further, the upper ends of the inner cover 19a and the outer cover 19b of the reinforcing cover 19 do not necessarily have to be arranged outside the dam plate device 6, and the same effect can be expected even if they are arranged inside the dam plate device 6.

Further, in the above embodiment, the case where the door surface portion 7d of the bag body 7 is provided with the cargo discharge port 14 in advance has been described. However, at the time of cargo discharging, the lower end of the door surface portion 7d may be a knife or the like. The same can be applied to the container inner bag of the type in which the cargo discharge port is provided by partially cutting off at. In this case, the opening 20 of the inner cover 19a can be used as a guide when determining the cutting position of the door surface portion 7d.

When the lower end of the door surface portion 7d is cut off to provide a cargo discharge port, the outer cover 19b may be omitted if necessary, and the opening 20 of the inner cover 19b may be omitted.

[0036]

[Effect of device]

 As described above, according to the present invention, since the lower part of the door surface of the bag body is reinforced by the reinforcing cover arranged on the outside thereof, even if a large force is applied to the lower part of the door surface from the cargo side during cargo discharge. It is possible to sufficiently support this and prevent the door surface from being torn.

Further, in the present invention, by providing a cylindrical cargo discharge port on the door surface, the cargo can be discharged reliably to a predetermined position according to the conditions of the receiving side, and the cargo discharge port is narrowed down. By doing so, it is possible to adjust the discharge amount of the cargo. In addition, the work is easy even when the cargo is discharged in multiple places.

Further, by providing the opening corresponding to the cargo discharge port provided on the door surface in the reinforcing cover, it is not necessary to cut off a part of the reinforcing cover to provide an opening when discharging the cargo, which facilitates the work. In addition, there is no risk that cutting chips will enter the cargo as foreign matter. In addition, when the door surface is cut off to provide a cargo discharge port, the opening of the reinforcing cover serves as a guide when determining the cutting position and range, so the cutting work is easy.

Further, by constructing the reinforcing cover from the inner cover and the outer cover, it is possible to cut the door surface to provide a cargo discharge port, or to provide a cargo discharge port in advance. The outer cover can prevent stains around the discharge port, and foreign matter can be prevented from entering the discharged coins.
