Description

  The present invention relates to a container container used for transporting and storing various fluids, and relates to a container interior container in which an inner bag as an interior body is stored.

  FIG. 4 shows a conventional container container. A container container 1 used for transporting and storing various fluids is provided with a discharge cylinder 4 at the bottom of a metal container body 3 which is self-supported by a plurality of support legs 2. The open / close valve 5 is connected to the discharge cylinder 4, and the upper portion of the container main body 3 has a lid member 6 and air previously contained in the container container for storing and exchanging stored items. The internal pressure relief nozzle 7 for venting air to be taken out, and the air intake for smoothing the take-out of the stored matter by taking atmospheric pressure into the container when the internal pressure is released and from the discharge cylinder of the stored item. An air inlet / outlet nozzle 8 is also provided which also serves the purpose.

  When storing a storage object made of a fluid such as a liquid or a granular material in the container body 3, the storage object is dropped and introduced into the container body 3 from the upper lid member 6, and the storage object is taken out. Is configured to take out the stored items from the bottom through the discharge cylinder 4 by opening the open / close valve 5 connected to the discharge cylinder 4.

  FIG. 5A shows a case in which a container a made of a liquid or granular fluid is directly stored in the container container 1, and FIG. 5B shows an internal pressure relief nozzle 7 for taking out the container a from the container container. The function of the air inlet / outlet nozzle 8 is shown.

  First, as shown in FIG. 5 (A), when the stored item is introduced from the lid member 6 at the top of the container body 3, a hose is connected to the filling port 9 provided in the lid member 6 or directly by hand. The stored item a is stored in the container main body 3 through the filling port 9. At this time, the internal air of the container main body 3 accompanying the storage of the stored item a in the container main unit 3 is released from the internal pressure relief nozzle 7. It is discharged to the outside through the air inlet / outlet nozzle 8, and the stored item a can be stored smoothly.

  Next, as shown in FIG. 5 (B), when the stored item a is taken out from the opening / closing valve 5 through the discharge cylinder 4 at the lower part of the container body 3, the decompression accompanying the decrease of the stored item a in the container body 3 is performed. The problem is solved by introducing external air through the air inlet / outlet nozzle 8. If the stored item a has a risk of explosion or the like, the inert gas may be introduced into the container body 3 by connecting the air inlet / outlet nozzle 8 directly to an inert gas tank such as nitrogen.

By the way, recently, a fluid is stored in an inner bag attached to the inside of the container container main body 3, and a cylindrical nozzle attached to the bottom of the inner bag main body so as to communicate with the inside is positioned in the discharge cylinder 4. In addition, by storing the stored items in the inner bag, there is one in which no direct contact occurs between the stored item and the container main body 3 and the discharge cylinder 4, and the inner bag for these container containers was used. In the case of changing the type of the stored item, the inner bag only needs to be replaced, so that there is an advantage that the cleaning of the container body becomes unnecessary and the cleaning cost can be reduced (for example, Patent Document 1 and Patent Document 2).
Japanese Patent No. 2915342, FIG. Japanese Patent Laid-Open No. 2000-168888, FIG.

  Even when the above-described inner bag for a container container is used, when the inner bag is used as it is for a conventional container container, the following problems have occurred.

  When the inner bag 10 is introduced as an interior container into the conventional container container 1 that does not consider the storage of the inner bag as shown in FIG. 4, first, when storing the stored item a, as shown in FIG. Since the inner pressure relief nozzle 7 and the air inlet / outlet nozzle 8 cannot be discharged to the outside due to the presence of the inner bag 10 and the air cannot be released due to the introduction and exchange of the stored item a, the cover member 6 is provided. As shown by the arrows in the figure, air blows back at the filling port 9 storing the stored item a, and the introduction of the stored item a does not go smoothly. In particular, the hose is connected to the filling port 9 in a sealed state. In storage, there is a possibility that feeding cannot be performed.

  When taking out the stored item a, the air introduced from the air inlet / outlet nozzle 8 enters between the inner wall of the container body 3 and the outer side of the inner bag 10 as shown in FIG. With the discharge from 4, the inner bag 10 contracts and moves away from the inner wall of the container body 3.

  If the inner bag 10 continues to be taken out as it is and the inner bag 10 contracts too much, the inner bag 10 no longer contracts. In this case, the stored item a cannot be taken out.

  6B, if the stored item a is stored again from the lid member 6 while the inner bag 10 is left as it is, the air between the inner wall of the container body 3 and the inner bag 10 is used to some extent. Can be released from the nozzles 7 and 8, but the inner bag 10 is repeatedly expanded and contracted in the container body 3 each time.

  As described above, when the inner bag 10 separates from the inner wall of the container main body 3 and repeatedly expands and contracts in the container container 1 every time the stored item a is put in and out, the inner wall of the container main body 3 with the inner bag 10 or the inner bag The inner bag 10 is damaged by the friction between the ten, and the stored item a comes out of the inner bag 10, and the purpose of preventing the direct contact between the stored item a and the container container main body may be lost. is there.

  Further, even if the container container 1 is transported in a state where the inner bag 10 is separated from the inner wall of the container main body 3 in the container container 1, the inner wall of the container main body 3 with the inner bag 10 or the inner bag 10 similarly. The inner bag 10 may be damaged due to friction between the two.

  Therefore, the problem of the present invention is that in the container interior container in which the inner bag is stored inside the container container, it is possible to obtain a smooth introduction and discharge of the stored items, and further, an accident due to the damage of the inner bag does not occur. It is to provide a container interior container.

  In order to solve the above-described problems, the present invention provides a container body having an opening in the upper part, a lid member having an openable / closable hole for closing the opening and introducing a stored item, and a lower part of the container body. It consists of a connected discharge cylinder for discharging stored items and a replaceable inner bag made of a flexible material provided inside the container body, and is fixed with the opening and the lid member sandwiching the opening of the inner bag. The container interior container is a container interior container in which the lid member is provided with a nozzle for intake and exhaust of air in the container container.

  According to the configuration of the present invention, the air intake / exhaust provided in the lid member in which the inner bag does not exist between the container main body and the stored item is caused by the air in and out of the container container when the stored item is put in and out of the container container. As a result, the discharge of air is not obstructed by the presence of the inner bag, and the inner bag is not deflated in the container container due to outside air entering the gap between the inner wall of the container container and the inner bag.

  According to the present invention, in a container interior container with a built-in inner bag, even if the inner bag is used, the exchange of air in the container container accompanying the storage and discharge of the stored item is performed without any trouble, so that the stored item can be taken in and out smoothly. Yes.

  In addition, the inner bag does not repeatedly contract and expand in the container container as the stored item is taken in and out, and the stored item is damaged by the inner bag and the inner wall of the container container, or the inner bag is damaged due to friction between the inner bags. Accidents such as spills do not occur.

  Hereinafter, a container interior container according to an embodiment of the present invention will be described.

The state which attached the outer cover 18 is shown.

  The inner lid 17 fitted into the upper opening 16 of the container body 13 is provided with a short cylindrical filling port 19 projecting to the outside for introducing a stored item into the container body 13 at the center thereof. Usually it is closed by a cap 20.

  In addition, short cylinder-shaped inner lid internal pressure relief nozzles 21 and inner lid air inlet / outlet nozzles 22 that protrude outward are provided on the left and right sides of the filling port 19, respectively.

  The inner lid 17 is fitted into the container body 13 by the inner lid stopper stopper 23 provided around the opening 16 of the container body 13 to prevent the inner lid 17 from falling into the container. The inner bag 24 is fixed by sandwiching the vicinity of the upper opening of the inner bag 24 made of a flexible material such as PE between the stopper stopper 23 and the inner lid 17.

  An outer lid 18 is installed on the inner lid 17, and the outer lid 18 has an inner lid internal pressure relief nozzle 21 and an inner lid air pressure relief nozzle 25 at positions corresponding to the inner lid air inlet / outlet nozzles 22. An outer lid air inlet / outlet nozzle 26 is provided, and the nozzles 25 and 26 are fitted and fixed to the nozzles 21 and 22 on the inner lid 17 side as shown in FIG.

  A single-acting safety valve 27 connected to the outer lid internal pressure relief nozzle 25 is provided immediately above the outer lid internal pressure relief nozzle 25 on the upper surface of the outer lid 18. A nitrogen / air inlet / outlet port 28 which is connected and bent in the horizontal direction and is appropriately formed of a joining means is provided.

  In the portion where the inner lid internal pressure relief nozzle 21, the outer lid internal pressure relief nozzle 25, and the single-acting safety valve 27 are combined, it becomes a one-way valve from the inside of the container container to the outside, and inside the container body 13 of the container interior container 11 Used to release the internal air when the internal pressure increases.

  In addition, in the portion where the inner lid air inlet / outlet nozzle 22, the outer lid air inlet / outlet nozzle 26, and the nitrogen / air inlet / outlet 28 are combined, the flow of air in both directions into and out of the container container is permitted from the outside. In addition to being used for releasing the internal air when the internal pressure of the container interior container 11 increases, the nitrogen / air inlet / outlet 28 is connected to a nitrogen tank, an air tank, etc. When the air pressure decreases, air or the like is sent to keep the internal pressure within a predetermined range. In addition, when the stored item is explosive, an inert gas such as nitrogen is introduced.

  An air inlet / outlet nozzle 29 is provided on the upper surface of the container body 13 in the same manner as a conventional container container. When the inner bag 24 is mounted in the container body 13, the inner body 24 is opened in the opening 16. After the bag 24 is put, the inner bag 24 is filled with air and inflated so as to be in close contact with the inner wall of the container body 13, but at this time, it is between the inner wall of the container body 13 and the inner bag 24. Air is discharged to the outside through the air inlet / outlet nozzle 29.

  When the inner bag 24 is replaced, air is introduced into the air inlet / outlet nozzle 29 from the outside to contract the inner bag 24 in the container body 13, and the contracted inner bag 24 opens the opening of the container body 13. It is taken out from the unit 16 to the outside.

  The container interior container 11 of the present invention is configured as described above. Next, the manner in which the stored items are stored in the container interior container 11 will be described with reference to FIG.

  FIG. 3 (A) is a front cross-sectional view when the stored item a is stored in the container interior container 11 of the present invention, and the cap 20 that removes the outer lid 18 and seals the filling port 19 of the inner lid 17 is shown. Remove the hose and connect the hose to the container body 13 through the hose, or place a funnel-shaped device (not shown) on the filling port 19 and then apply gravity from above. The stored item a is dropped and stored.

  At that time, in exchange for the stored item a contained in the container main body 13, the internal air is used as an inner lid internal pressure relief nozzle 21 and an inner lid air inlet / outlet nozzle of the inner lid 17 where the inner bag 24 is not interposed between the inner bag 24 and the outside. Since the air is discharged from the outside 22, there is no air blowback or the like at the filling port 19, so that the stored item a can be stored smoothly.

  After storing the stored item a, the outer lid 18 is fitted on the inner lid 17, and the stored item a is stored or transported in some cases in this state. When the internal pressure inside the container main body 13 increases due to volatilization of the internal pressure, the internal air is discharged to the outside through the internal lid internal pressure relief nozzle 21 and the internal lid air inlet / outlet nozzle 22 to keep the pressure inside the container constant.
