  In this case, the other end portion of the projecting piece main body provided with the hook portion is disposed closer to the inside of the container main body along the container axial direction than the one end portion. When engaged with the opening edge, the dispensing cylinder can be inserted in advance into the inlet of the container. Accordingly, the refill container can be combined with the present container in a stable state at the stage before refilling, and the contents are more difficult to spill during refilling.

(4) In the refill container according to the present invention, it is preferable that a tip end portion of the dispensing cylinder is inclined obliquely with respect to the container axis.

  In this case, the tip of the dispensing cylinder is inclined, so that the closing plate closing the outlet can be inclined, and the dispensing cylinder is moved to the inside of the container. In this case, it is easier to hit the closing plate with less resistance.

(5) In the refill container according to the present invention, it is preferable that the hook portion is connected to the extraction tube via a breakable connecting portion.

  In this case, since the position of the hook portion is stabilized, the hook portion can be easily engaged with the opening edge of the inlet of the container. Thereby, the refilling operation can be performed more simply. In addition, before the refilling operation, it is possible to prevent the closing plate from being rolled and opened due to rattling of the hook portion or the like.

(6) In the refill container according to the present invention, it is preferable that a plurality of the operation projecting pieces are provided.

In this case, since a plurality of operation protrusions are provided, when arranging the pouring tube so as to face the injection port of the main container, the plurality of hook portions are connected to the opening end of the injection port of the main container. It can be engaged with the edge. Therefore, the refill container can be combined with the present container in a stable state, and the contents are more difficult to spill during refilling.
In this case, when the hook portions are separately disposed at positions opposite to each other with the container shaft in the radial direction, the refill container can be combined with the present container in a more stable state.
