The rotor C is fixed so that it does not rotate freely with respect to the container main body B by engaging and engaging the outer side of the side protrusion 24c with the side end face 15b.

  At the same time, as shown in FIGS. 7 and 8, the notch 22 of the ring wall 20 of the rotating body C is positioned at a position corresponding to the flange 4, so that it rotates with the upper surface of the flange 4 of the inner container A. The contact of the body C with the ring wall 20 is removed, and the inner container A can be easily removed from the container body B.

  When the refill container of this embodiment is released from the locked state, the inner container A after use of the contents is taken out, a new inner container A filled with the contents is set in the container body B, and the inner container A is locked again. Since it can be used in a state, it can be used repeatedly as a refill container.

Furthermore, the refill container of the present embodiment is as shown in FIGS. 2 (a) and 3 (a) when viewed from above the rotating body C through the notch 22 of the ring wall 20 and in a locked state. When the upper upper surface 11 formed in the mouth tube part k of the main body B is seen and the locked state is released, as shown in FIGS. 7 (a) and 8 (a), the collar part 4 of the inner container A is visible. The inner container A is locked with respect to the container main body B by changing the colors of the inner container A and the container main body B, or by changing the color of the flange portion 4 and the mouth tube portion k visible in the locked state. Can be easily confirmed by visually recognizing from above the rotating body C.
In addition, by displaying “unlocked” on the upper surface of the flange portion 4 by characters, and by displaying “locked state” by characters on the mouth tube portion k of the container body B that can be seen from the notch portion 22 in the locked state. The lock state of the inner container A may be visually confirmed.

  Since the refill container of the present invention can change the locked state of the inner container with respect to the container body simply by rotating the rotating body, the inner container can be easily replaced, and the locked state can be changed above the rotating body. Therefore, it can be widely used as a refill container for reusing the container body.
