[0042] [How to install the container door fixing jig] Next, a method of mounting the container door fixing jig 1 according to this embodiment will be described. When mounting the container door fixing jig 1 to the container 100, the main body side mounting part 2 is mounted to the upper edge of the side surface 110a adjacent to the open surface 111 of the container main body 101, and the door side mounting part 3 is mounted to the upper edge of the container door 102 in an open state. Specifically, as shown in FIG. 8, after the upper edge of the container main body 101 is inserted into the opening between the main body side first support part 21 and the main body side second support part 22, the distance between the main body side first support part 21 and the main body side second support part 22 is adjusted to match the width of the upper edge of the container main body 101, and the thumbscrew 23 inserted through the insertion holes provided in the main body side first support part 21 and the main body side second support part 22 is tightened, so that the thumbscrew 23, the main body side first support part 21, and the main body side second support part 22 press the upper edge of the container main body 101, and the main body side mounting part 2 is mounted to the container main body 101.

[0043] After the above steps, as shown in FIG. 9 , the upper edge of the container door 102 in an open state is inserted into the opening between the door-side first support part 31 and the door-side second support part 32, and then the distance between the door-side first support part 31 and the door-side second support part is adjusted to match the width of the upper edge of the container door 102. By tightening the thumbscrew 33 inserted through the insertion holes of the door-side first support part 31 and the door-side second support part 32, the thumbscrew 33, the door-side first support part 31 and the door-side second support part 32 press the upper edge of the container door 102, and the door-side mounting part 3 is attached to the container door 102.

[0044] By going through the above-mentioned steps, the container door fixing jig 1 is attached to the container 100. Conversely, when removing the container door fixing jig 1, the body-side mounting part 2 is removed from the upper edge of the side surface 110a of the container body 101 by loosening the thumbscrew 23, and the door-side mounting part 3 is removed from the upper edge of the container door 102 by loosening the thumbscrew 33, so that the container door fixing jig 1 can be removed from the container 100. Note that the steps of attaching the body-side mounting part 2 and the door-side mounting part 3 are not limited to the above-mentioned order, and may be performed in any order, or may be performed simultaneously.

[0045] [How to secure the container door] Next, a container door fixing method using the container door fixing jig 1 will be described in detail with reference to Figures 4 to 7. The container door fixing method according to this embodiment is, in outline, a method for fixing the container door 102 of a container 100 including a container body 101 with at least one of a plurality of side faces 110 being open, and a rotating container door 102 capable of opening the open face 111 of the container body 101, and includes a step of attaching one mounting part (body side mounting part 2) of the container door fixing jig 1 to the upper edge part of the side face 110 adjacent to the open face 111 of the container body 101, and a step of attaching the other mounting part (door side mounting part 3) of the container door fixing jig 1 to the upper edge part of the container door 102 in the open state, and maintains the container door 102 in an open state along the extension direction of the side face 110 of the container body 101 to which one mounting part of the container door fixing jig 1 is attached. A specific method for this will be described below, but as the process for attaching the container door fixing jig 1 to the container 100 is the same as the method for attaching the container door fixing jig described above, a detailed description will be omitted.

[0046] First, as shown in Fig. 6, the container door 102, which is configured to be freely opened and closed, is opened along the extending direction of one side surface 110a of the container body 101. Here, "along" one side surface 110a of the container body 101 means that the container door 102 is opened about 90 degrees from the closed state, and the one side surface 110a of the container body 101 and the container door 102 are in a substantially straight line. "About 90 degrees" here is not limited to the case where the opening angle of the container door 102 is 90 degrees (a right angle), but also includes, for example, a case of about 80 degrees to 100 degrees.

[0047] Next, as shown in Figures 4 and 5, the body-side mounting part 2 is inserted into the upper edge of one side surface 110a of the container body 101, and the door-side mounting part 3 is inserted into the upper edge of the container door 102 in the open state.

[0048] Thereafter, the body-side mounting part 2 and the door-side mounting part 3 are respectively attached to the container body 101 and the container door 102 as described above, so that the connection part 4 is provided at a position facing one side surface 110a of the container body 101 and the inner surface of the container door 102, and the container door 102 is fixed along the extending direction of the side surface 110a, as shown in FIG. 7. The door-side mounting part 3 is configured so that the manner of fixing the container door 102 can be changed by adjusting the distance between the door-side first support part 31 and the door-side second support part 32. That is, the distance between the door-side first support part 31 and the door-side second support part 32 can be adjusted to a position where the door-side first support part abuts against the container door 102, and the container door 102 can be fixed immovably at the angle of the open state by pressing the door-side first support part with the container door 102 by using the thumbscrew 33. Conversely, by adjusting the distance between the door side first support portion 31 and the door side second support portion 32 to a position where the door side first support portion does not abut the container door 102, the container door 102 in the open state can be locked in a state where it can swing slightly.
