  In Patent Document 1, the container body is attached to and detached from the liquid ejector for replacement. However, depending on the type of the content, the user may find that dust may enter the content during the replacement work. May feel anxious.

  Further, in the replacement work, there is a possibility that the user turns the liquid ejector in the screwing direction of the outer case body with respect to the liquid ejector.

  As a means for preventing the liquid discharger of the refill container from rotating in the wrong direction, for example, a ratchet mechanism that restricts the rotation in the opening direction between the peripheral surface of the liquid discharger and the opposing surface of the other member is used. It is conceivable to provide it.

  However, in recent years, it has been demanded to adopt a certain standard as the main part (liquid ejector) of the container so as to be able to cope with a large variety of small-volume production. Therefore, it would be advantageous to use a dispenser that does not have a special mechanism such as a ratchet to prevent rotation in the wrong direction.

  A first object of the present invention is a refill container of a type in which a discharger and a container body are screwed and replaced with respect to an outer case body, and has a mechanism capable of preventing a rotation operation in a wrong direction at the time of replacement. It is to propose.
