(In general, the ratio of the outer diameter of the mouth and neck to the outer diameter of the bottom surface of the container is about 0.3 to 0.6.)

  For this reason, in order to correspond to such a container shape, the support members described in Patent Documents 1 to 4 have a dimension and shape that can be inserted from the mouth and neck of the container, or are inserted from the mouth and neck of the container. After that, it must be shaped so as to spread in the container. In this case, an unnecessary load may be applied to the container.

  Moreover, in the support member described in patent documents 1-4, since the self-supporting property of itself is bad, there is a defect that it lacks stability when the removed support member is placed at the time of replacing the container. is there. In addition, there is a drawback in that the content liquid tends to adhere to the hand when the support member is inserted from the mouth and neck of the container during the container replacement operation.

On the other hand, it is desirable to clean the container after use and then discard it. However, in the case of the container shape described above, there is a drawback that it is difficult to clean the inside of the container because the diameter of the mouth and neck portion is small.
