  The present invention relates to an inner bag of a container container used for transporting and storing various fluids and a method for using the same.

  As shown in FIG. 7, a container container 1 used for transporting and storing various fluids includes a metal container body 3 that is self-supported by a plurality of support legs 2, and a discharge provided at the bottom of the container body 3. The discharge cylinder 4 is formed of a cylindrical pipe, which is suspended from the bottom of the container body 3 and bent horizontally from the middle. An opening / closing valve 25 is connected to the distal end of the discharge cylinder 4. The stored item is taken out by operating the opening / closing valve 25.

  Recently, the inner bag 5 is mounted inside the container body 3 and a nozzle attached to the bottom of the inner bag body 6 so as to communicate with the inside is positioned in the discharge cylinder so that liquid or liquid can be contained in the mounted inner bag 6. By storing the fluid such as powder, there is no direct contact between the fluid and the container body 3, and when changing the type of fluid to be stored, the inner bag 5 may be replaced. There is an advantage that cleaning inside the container body 3 is not necessary, and cleaning costs can be reduced.

  The nozzle in the conventional inner bag is formed of a flexible material so that it can correspond to the bent shape of the discharge tube 4, and its upper end is connected to the bottom of the inner bag body by welding or the like and integrated with the inner bag body This structure prevents contact between the container container, its discharge cylinder, and the fluid as the stored material (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).

  By the way, the inner bag needs to insert the nozzle into the discharge cylinder when mounted in the container container, and the discharge cylinder has a shape that hangs down from the bottom of the container body and is bent horizontally from the middle. Therefore, it is extremely difficult to insert the nozzle located at the lower end of the inner bag into the discharge cylinder, and when replacing the inner bag of the container container, the nozzle is pulled into the discharge cylinder, but the nozzle tip is opened. If so, there is a problem that the fluid remaining in the nozzle flows out from the nozzle tip and contaminates the discharge tube 4 and the inner wall of the container body 3.

Therefore, one end of the nozzle is joined to the front end of the nozzle, folded on the outer surface of the bellows cylinder, and provided with a flexible cylindrical body that covers the lower end of the bellows cylinder when extended. Adopting a string-like member having a required length attached to the bellows tube, and when inserting the nozzle into the discharge cylinder, by passing the string-like member through the discharge cylinder and pulling this string-like member from the open end, The bellows tube can be pulled from the container body into the discharge tube, and when replacing the inner bag, the flexible cylindrical body folded on the outer surface of the bellows tube is extended and its end is tied up An inner bag has also been proposed that can close the tip of the nozzle so that fluid does not spill from the nozzle into the discharge cylinder, and is convenient for attaching and detaching the inner bag (for example, Patent Documents). 4).

For example, in the case shown in FIG. 3 (A), by opening a hole in the vicinity of the opening 22 at equal intervals along the periphery of the opening and passing the string 23 there, the string 23 is pulled. The opening 22 can be closed, and in the case shown in FIG. 3B, a rubber band 24 is embedded along the periphery of the end opening so that the opening 22 always works in the contraction direction. .

  The contraction means is not limited to that shown in FIG. 3, and various known means can be used. In short, the end opening of the flexible cylindrical body 12 can be arbitrarily enlarged and reduced (including closing). If it is something like that.

  The inner bag 5 of the present invention is configured as described above, and the periphery of the hole provided in the bottom of the inner bag body 6 is reinforced with a reinforcing member 21 made of a material similar to that of the inner bag body 6, and then the hole is formed in the hole. The attachment tube 9 is inserted from the inside, and the flange 8 is attached to the bottom of the inner bag body 6 so as to communicate with the inside, and is attached to the lower end of the attachment tube 9 projecting from the inner bag body 6 to the outside. The upper cylindrical portion 15 of the bellows tube 11 is connected by bonding, welding, or the like.

  Further, the string member 13 is attached and fixed to the lower end cylindrical portion 16 of the bellows tube 11 to assemble the nozzle 7, and the inner bag 5 having the nozzle 7 attached to the bottom portion is completed as shown in FIG.

  In order to load the inner bag 5 into the container container 1 as described above, as shown in FIG. 1A, the inner bag body 6 is folded up and down into a long and flat shape, and in this state, the nozzle 7 is lowered. Then, the inner bag 5 is inserted into the container container 1 from the opening portion on the upper surface, and the string-like member 13 is caused to enter the discharge cylinder 4 with the weight 19 hanging down due to gravity as the head.

  At the same time, a rod (not shown) provided with a magnet at the tip end is inserted from the tip opening side of the discharge cylinder 4, and the weight 19 is pulled out after being attracted by a magnetic force. If the string 18 is subsequently pulled out, the collar portion 10 of the bellows tube 11 is pulled out so as to be positioned outside the discharge tube 4.

  The flange portion 10 provided at the end of the bellows tube 11 passes through the discharge tube 4 in a compressed state, is restored when it goes out of the discharge tube 4, and is locked to the end of the discharge tube 4. As a result, the discharge tube 4 is prevented from returning to the inside of the bellows tube 11.

  Moreover, since the bellows tube 11 has expansion and contraction and bendability, it has a following capability with respect to the shape of the discharge tube 4 having a bent portion, and can cope with the discharge tube 4 having different shapes. The versatile nozzle 7 can be formed.

  The fastening member 20 of the string-like member 13 is removed, the fastening belt 17 is unfastened, and the string-like member 13 is removed from the bellows tube 11. The removed string-like member 13 can be reused as it is as a string-like member of another container inner bag.

  As shown in FIG. 4, after the string-like member 13 is removed, the contraction of the other end portion of the flexible tubular body 12 provided with the contraction means is released (if the contraction means is rubber, the opening is manually expanded) Then, as shown by the two-dot chain line in the figure, the battery is pulled out from the discharge cylinder 4.

  Next, the flexible tubular body 12 folded over the outside of the discharge cylinder 4 is pulled back to the opening / closing valve 25 side again, and the contraction means is contracted at the flange portion 27 of the opening / closing valve 25 so that the opening / closing valve 25 The flexible cylindrical body 12 is connected to the open / close valve 25 by tightening the outer peripheral surface (FIG. 6B).

  Thereafter, the opening / closing valve 25 is pulled away from the discharge cylinder. At this time, even if there is a residue of the stored item a remaining in the discharge cylinder 4 or the opening / closing valve 25, the joint between the discharge cylinder 4 and the opening / closing valve 25 is separated. In this case, all the residue a is contained in the flexible cylindrical body 12 and does not spill outside (FIG. 6C).

  After the opening / closing valve 25 is pulled away from the discharge cylinder 4, the contracting means is released, the flexible cylindrical body 12 is removed from the collar portion 27 of the opening / closing valve 25, and the string 23 or the rubber band 24 as the contracting means is contracted as it is. Or the edge part opening part of the flexible cylindrical body 12 is closed by fastening with another member (FIG.6 (D)).

  Thereafter, when the entire inner bag 6 is pulled out from the upper surface opening of the container body 3, the nozzle 7 is also extracted from the discharge tube 4 at the same time, and at this time, the end of the flexible cylindrical body 12 is closed. Therefore, liquid dripping or the like in which a fluid spills into the discharge cylinder 4 from the mouth of the bellows cylinder 11 at the time of taking out does not occur.

  Thus, the container container 1 has the inner surface of the container main body 3 covered with the inner bag main body 6 and the nozzle 7 is present inside the discharge tube 4, so there is no contact between the stored fluid and the container container 1. It is only necessary to replace the inner bag 5 when changing the fluid, and the inside of the container main body 3 and the inside of the discharge tube 4 are not required.
