  Next, a method for refilling the contents from the refill container 1 configured as described above into the main container 40 will be described.

First, after removing the stopper 8 from the refill container 1, the refill container 1 is placed above the main container 40 in a state where the refill container 1 is in an inverted posture and the main container 40 is in an upright posture. Then, the refill container 1 and the main container 40 are moved relative to each other in the direction of the container axis O while aligning them, and the flange portion 21 of the operation member 6 is moved to the spout 41 of the main container 40 as shown in FIG. The refill container 1 and the main container 40 are combined in contact with the opening edge.
At this time, the insertion cylinder portion 24 and the guide rib 25 of the operation member 6 of the refill container 1 are inserted into the spout portion 41 of the main container 40 and disposed in the spout portion 41. In particular, the guide rib 25 is inscribed in the spout portion 41.

Here, in the present embodiment, as described above, the refill container 1 is turned upside down, so that the top and bottom of the refill container 1 are inverted, and the operation member along the container axis O direction in the refill container 1 in the inverted position. The 6 side is the lower side, and the container body 2 side is the upper side.
Further, since the spout 3 of the refill container 1 is closed by the seal portion 5, the contents in the container body 2 do not flow out to the outside through the spout 3 even when the refill container 1 is turned upside down. Further, since the operation member 6 is supported by the connecting body 7, it is difficult for the operation member 6 to slide by simply bringing the flange portion 21 into contact with the spout portion 41.
In addition, since the seal ring 5b is fitted to the lower opening end of the central cylindrical portion 14 of the mounting portion 4 so as to be sandwiched from the inside and outside in the radial direction, the seal portion 5 is opened by the weight of the contents. Is prevented.

Then, as shown in FIG. 3, when the container body 2 of the refill container 1 and the main container 40 are relatively moved along the container axis O direction, the connecting body 7 is connected to the mounting portion 7 a. The connecting portion 7b with the operation member 6 is rotated so as to move toward the spout 3 along the container axis O direction. Thereby, the operation member 6 can be slid toward the spout 3 as the connection body 7 rotates, and at least one of the pressing cylinder portion 20 of the operation member 6 and the connection plate 23 of the operation member 6. One presses the seal body 5 a of the seal portion 5 to disengage it from the spout 3, opens the spout 3, and enters the inner cylinder portion 10 of the mounting portion 4.
When the connecting plate 23 presses the seal body 5a, the connecting plate 23 functions as a pressing body.

  Thereby, the inside of the container main body 2 of the refill container 1 and the inside of the spout 41 of the main container 40 communicate with each other through the spout 3 and the opening 23 a of the connecting plate 23. Therefore, the contents accommodated in the container body 2 of the refill container 1 can be poured out into the spout 41 of the main container 40 through the opening 23a (arrow A shown in FIG. 3). Can be refilled from the refill container 1 to the main container 40.

In the present embodiment, when the container body 2 of the refill container 1 and the main container 40 are moved relatively close to each other, the central cylindrical portion 14 and the flange portion 21 of the mounting portion 4 come into contact with each other, so that the close movement is prevented. Be regulated.
Further, during the refilling operation, the inside and the outside of the container 40 are communicated with each other through the gap between the spout part 41 and the insertion cylinder part 24 defined by the guide rib 25 and the groove part 26 formed in the flange part 21. Can be made. Therefore, air replacement in the main container 40 can be performed through the gap and the groove portion 26 (arrow B shown in FIG. 4), and the contents can be smoothly poured into the main container 40 to perform the refilling work efficiently. it can.

By the way, in this embodiment, in the state shown in FIG. 3, the pressing cylinder portion 20 of the operation member 6 protrudes upward from the opening 23 a, and the tip thereof is located near the bottom of the seal body 5 a of the seal portion 5. Yes. Therefore, it is difficult for the contents to be poured out to the main container 40 side through the inside of the pressing cylinder portion 20, and the preferential passage passes through the opening 23a.
Therefore, in this embodiment, the press cylinder part 20 can be functioned as a member for mainly pressing the seal part 5. FIG. In addition, it is also possible to make the inside of this press cylinder part 20 function as a passage for air replacement between the main container 40 and the refill container 1.

As described above, according to the refill container 1 of the present embodiment, after the refill container 1 and the main container 40 are combined with the flange portion 21 in contact with the opening edge of the spout portion 41, the container body 2 Since the contents can be refilled by a simple operation of relatively moving the container 40 and the main container 40 along the container axis O direction, the refilling operation can be facilitated.
Further, when refilling, the flange portion 21 of the operation member 6 is brought into contact with the opening edge of the spout portion 41, so that the refill container 1 in the inverted posture can be combined with the main container 40 in a stable state, and the operation Since the insertion cylinder part 24 and the guide rib 25 of the member 6 can be inserted into the spout part 41, the refill container 1 and the main container 40 can be combined without being displaced in the radial direction. Therefore, it can suppress that the contents spill.

In addition, the operation member 6 can be stabilized by bringing the flange portion 21 into contact with the opening edge of the spout portion 41 as described above, and the operation member 6 is attached to the mounting portion 4 via the connecting body 7. Since the connection member is supported, the operation member 6 can be smoothly slid without rattling, and the spout 3 can be easily opened by pressing the seal portion 5 without requiring excessive force. In this respect, the refilling operation is easy to perform.
Furthermore, since the contents can be refilled in the main container 40 simultaneously with the opening of the refill container 1, the refilling operation can be performed without placing the main container 40 in an inverted posture. The contents can be refilled even if there is a residue.

Further, as shown in FIG. 1, since the stopper 8 is mounted on the central cylindrical portion 14 of the mounting portion 4 to restrict the downward movement of the flange portion 21, an external force is unexpectedly applied to the refill container 1 at the distribution stage or the like. Even if it is added, it becomes possible to restrict the sliding movement of the operation member 6 to suppress the pressing cylinder portion 20 from pressing the seal portion 5, and to prevent the refill container 1 from being opened unexpectedly. Can do.
In addition, since the stopper 8 closes the insertion cylinder portion 24 of the operation member 6, it is possible to prevent dust and the like from entering from the outside and adhere to the pressing cylinder portion 20 and the seal portion 5 and the like. It is easy to prevent foreign matter from entering.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, the fitting force of the seal portion 5 with respect to the spout 3 is such that the seal body 5 and the seal portion 5 are self-weighted in a state where the seal portion 5 is brought into contact with the pressing cylinder portion 20 in the refillable container 1 in the inverted posture. It is preferable to set it to such an extent that the part 5 cannot be separated from the spout 3.

  In the above embodiment, the case where the flange portion 21 is formed in an annular shape has been described as an example. However, the flange portion 21 is not limited to an annular shape, and a plurality of flange portions may be formed at intervals in the circumferential direction. In any case, it is only necessary that the opening edge of the spout 41 of the container 40 can be contacted. However, when the flange portion 21 is formed in an annular shape, the posture of the refill container 1 can be further stabilized and the force can be easily transmitted to the operation member 6, so that the seal portion 5 is easily pressed.

Moreover, in the said embodiment, it is good also as a needle shape which made the lower end part of the press cylinder part 20 incline. By doing so, the seal portion 5 can be easily detached from the spout 3.
Furthermore, although the cylindrical pressing cylinder portion 20 has been described as an example of the pressing body, any configuration may be used as long as the seal portion 5 can be pressed as the operating member 6 slides. For example, the pressing body may be a rod-like or plate-like member extending in the container axis O direction. In this case, the number of pressing bodies may be one, or a plurality of pressing bodies may be arranged at intervals around the container axis O in the circumferential direction.

  Moreover, in the said embodiment, although it was set as the structure by which this spout 3 is open | released when the seal | sticker part 5 is pressed by the press cylinder part 20, and leaves | separates from the spout 3, it is not restricted to this, For example, The spout 3 may be opened by breaking the seal portion 5. In this case, for example, the seal portion 5 may be formed in a lid shape connected to the inner peripheral surface of the spout 3 via a breakable weakening portion, and is stretched inside the spout 3. It may be formed into a breakable film. In this case, a blade part that presses and seals the seal part 5 may be used as the pressing body.

  Moreover, in the said embodiment, although the insertion cylinder part 24 and the guide rib 25 were provided on the flange part 21, these are not essential and do not need to provide. However, when the refill container 1 and the main container 40 are combined, it is preferable to provide the refill container 1 because the posture of the refill container 1 is further stabilized and the both containers 1 and 40 are less likely to be displaced in the radial direction.
