A joining flange portion 61 is provided so as to have an outer diameter larger than the diameter of 12a.

  Further, like the inner container 11, the rectifying plate 27 is not provided with the depressed portion 28, the projecting portions 54 and 57, and the slit 60 on the outer peripheral portion 27 a. The outer peripheral portion 27a, like each embodiment, has a substantially cylindrical shape with a diameter reduced toward the partition wall portion 27b in a steeply inclined state close to vertical, and the outer diameter of the opening end having a large diameter. Is formed slightly smaller than the inner diameter of the first cylindrical portion 12 a of the first inner container member 12.

  In the fifth embodiment, before the second and third inner container members 15, 16 are joined to the first inner container member 12, the rectifying plate 27 is not press-fitted into the first inner container member 12. It arrange | positions so that it may accommodate from the partition part 27b side. Then, the joining flange part 61 of the 2nd inner container member 15 is made to contact | abut to the opening end of the 1st inner container member 12, and these are joined by welding. Thereby, in this joint flange part 61, the latching | locking part 62 is formed of the part which protrudes inward from the 1st inner container member 12. FIG.

  Then, after the third inner container member 16 is assembled to the second inner container member 15 by joining, the outer container 18 is joined to the inner container 11 and assembled, whereby the liquid container 10 shown in FIG. Is completed.

  In the liquid container 10 according to the fifth embodiment, the rectifying plate 27 is not locked inside the inner container 11, and is in a freely movable state inside the first inner container member 12. However, when the piping member 44 is attached to the liquid container 10 when assembled in the predetermined path, the overflow pipe 47 penetrates the through hole 30, and the second locking portion 48 of the overflow pipe 47 is connected to the current plate 27. By locking the flat portion 27 c, the rectifying plate 27 is positioned in a state where the upper and lower sides are sandwiched between the locking portions 62 and 48.

  As in the fourth embodiment, the liquid container 10 of the fifth embodiment configured as described above can be sandwiched and assembled by the locking portions 62 and 48 without joining the rectifying plate 27 to the inner container 11. Therefore, the assembly workability can be improved and the cost can be reduced. Further, it is possible to obtain the same operation and effect that it is possible to prevent foreign substances from being mixed into the liquid due to corrosion and to prevent the occurrence of leakage.

  The liquid container 10 of the present invention is not limited to the configuration of the above embodiment, and various modifications can be made.

  For example, in each of the above embodiments, the locking portion 48 that locks the lower surface of the rectifying plate 27 is provided on the overflow pipe 47 of the piping member 44. However, the rectifying plate 27 is closed by the pressure of the liquid that has flowed. Therefore, the engaging portion 48 may not be provided.
