As explained above, in the present invention, locking pieces for hanging strings are provided on the outer periphery of the lower end of the draining member attached to the upper end of the outer case and on the outer periphery of the threaded ring, and an annular cushioning material made of an elastic material is provided. A thick part is formed in the cushioning material, and an inwardly curved part which is curved inward in a top view is formed in the thick part, and a through hole is bored in the cushioning material. By passing the locking piece through the through hole, the buffer material is stretched around the outer periphery of the lower end of the draining member and the outer periphery of the threaded ring, so that By simply passing the locking piece through, the cushioning material can be easily stretched around the outer periphery of the draining member and the threaded ring.

In addition, since the cushioning material is provided around the outer periphery of the draining member and threaded ring, when the portable liquid container is placed horizontally, the outer case, draining member, bottom member, etc. do not come into contact with the ground surface. Since it is the thick part of the cushioning material that comes into contact with the ground, it has excellent impact resistance and there is no risk of damage to the inner bottle. In particular, when the thick part of the cushioning material comes into contact with the ground surface,
There is no risk that the portable liquid container will roll over, and it can be placed horizontally in a stable manner. Furthermore, since the thick portion is formed with an inwardly curved portion that curves inward when viewed from above, there is an economical effect that only a minimum amount of expensive cushioning material is required.
