However, the means for storing the contents together with the bag in the container has the following problems.
For example, when the container body is tilted and the contents are removed from the container body, the amount of the contents removed from the container body depends on not only the inclination of the container body but also the shape of the bag body stored in the container body. There was a problem that it was difficult to take out an appropriate amount. In addition, when the container body is made of a transparent material such as glass, the bag body can be seen through from the outside of the container body, so that the appearance of the container body is deteriorated. There is also a problem that it is difficult to check the remaining amount of contents because it is contained in the body.

  This invention is made | formed in view of the situation mentioned above, The objective is to provide the refill container which can transfer the contents in a refill container easily and for a short time.

In order to solve the above problems, the present invention proposes the following means.

Thereby, the operation | work which pushes a refilling container into the container body side becomes easy, and the contents in a refilling container can be transferred still more easily and in a short time.
Further, when the refill container is pushed into the container body, the force acting on the pressing portion from the opening edge of the mouth portion of the container body is transmitted over the entire circumference of the outer cylinder portion via the annular pressing portion. Therefore, the bending deformation of the outer cylinder portion can be stabilized and highly accurate regardless of the position around the container axis. As a result, the posture of the sealing material when the blade portion is pressed against the sealing material can be stabilized, and the sealing material can be ruptured smoothly and reliably by the blade portion.
In addition, by pressing the annular pressing portion against the opening edge of the mouth of the container body, it is possible to effectively suppress the communication between the inside and the outside of the container body by the pressing portion. When the contents inside are transferred into the container, the contents can be further prevented from touching the outside air.

  Further, in the refill container according to the present invention, the inner cylindrical portion is inserted inside the pressing portion in the radial direction, and the axial direction of the pressing portion when the outer cylindrical portion is bent and deformed. It may be configured to guide movement along.

  In this case, the inner cylindrical portion is inserted inside the pressing portion in the radial direction, and is configured to guide the movement of the pressing portion along the container axis direction when the outer cylindrical portion is bent and deformed. As a result, the posture of the sealing material when the blade portion is pressed against the sealing material can be made more stable, and the breaking of the sealing material by the blade portion can be made smoother and more reliable. .

  According to the refill container of the present invention, the contents in the refill container can be transferred easily and in a short time.

The abutting portion 11 is restricted from moving downward by the locking projection 10d.

Next, an example of how to use the refill container 1 shown above will be described.
Below, the case where the contents F in this refill container 1 are transferred to the cylindrical container body 20 different from the refill container 1 is demonstrated.

First, the cap 4 is removed from the container body 2.
Next, as shown in FIG. 2, the outer tube portion 9 is pressed against the opening edge 22 of the mouth portion 21 of the container body 20 after the contents F are used up in a state where the refill container 1 is in an inverted posture. The part 11 is pressed while positioning.
At this time, while the inner peripheral surface of the mouth portion 21 of the container body 20 is brought into contact with the outer peripheral surface of the outer end portion 9 d of the outer tube portion 9, the outer tube portion 9 is disposed inside the mouth portion 21 of the container body 20 in the radial direction. The outer opening 9a can be positioned. Moreover, in the illustrated example, the pressing portion 11 is provided with the positioning guide portion 11a, so that the refill container 1 can be positioned more reliably and easily.

Next, when the refill container 1 is pushed into the container body 20 side, the pressing portion 11 is pressed toward the inside of the container body 2 along the container axis O direction by the opening edge 22 of the mouth portion 21 of the container body 20. Is done.
At this time, while the outer cylinder portion 9 is bent and deformed, the inner peripheral edge portion 11d of the pressing portion 11 moves from the outer side of the container body 2 along the container axis O direction to the inner side along the container axis O direction, and is pushed. The locking of the locking projection 10d with respect to the abutting portion 11 is released. Thereby, the restriction | limiting of the movement to the inner side of the container main body 2 along the container axis O direction of the pressing part 11 is cancelled | released.

Next, when the refill container 1 is further pushed into the container body 20 side, the outer cylinder portion 9 is greatly bent and deformed along the container axis O direction. In the illustrated example, the connecting ring portion 12 and the pressing portion 11 are bent and deformed starting from a connecting portion 12a between the connecting ring portion 12 and the pressing portion 11 and a connecting portion 12b between the connecting ring portion 12 and the inner end portion 9b. Thereby, in the outer cylinder part 9, the outer side edge part 9d and the inner side edge part 9b approach along the container axis | shaft O direction.
Here, since the inner cylinder part 10 is inserted in the inner end part 9b of the outer cylinder part 9 in a state in which movement along the container axis O direction is restricted, the outer end part 9d of the outer cylinder part 9 and Along with the approach to the inner end 9b, the sealing material 8 that closes the outer opening 9a of the outer cylinder 9 and the blade 13 of the inner cylinder 10 also approach along the container axis O direction.

At this time, the inner peripheral edge portion 11d of the pressing portion 11 slides on the outer peripheral surface of the intermediate portion 10c of the inner cylinder portion 10 so that the movement of the pressing portion 11 along the container axis O direction is guided. Therefore, the sealing material 8 and the blade part 13 can be brought close to each other while the posture of the sealing material 8 is stabilized.

The relative positional relationship along the container axis O direction between the outer end portion 9d of the outer cylinder portion 9 located outside the container body 2 along the container axis O direction from the portions 12a and 12b and the container body 20 changes greatly. Instead, the refill container 1 moves so that the inner cylinder portion 10 enters the container body 20.

  Next, when the refill container 1 is further pushed into the container body 20 side, the blade portion 13 is pressed against the sealing material 8 as shown in FIG. 3, and the sealing material 8 is broken. As a result, the contents F in the container body 2 are poured into the container body 20 through the inner cylinder portion 10, and the contents F in the refill container 1 are transferred into the container body 20. At this time, as described above, since the outer opening 9a of the outer cylinder portion 9 is positioned on the inner side in the radial direction of the mouth portion 21 of the container body 20, the content F can be prevented from touching the outside air while being short. It can be moved into the container body 20 over time.

According to the refill container 1 shown above, the contents F in the refill container 1 can be transferred easily and in a short time.
Further, since the pressing portion 11 is formed in an annular shape, when the pressing portion 11 is pressed against the opening edge 22 of the mouth portion 21 of the container body 20 with the refill container 1 in the inverted posture, the pressing portion 11 The part 11 can be pressed against the opening edge 22 over the entire circumference. Thereby, the operation | work which pushes the refilling container 1 into the container body 20 side becomes easy, and the content F in the refilling container 1 can be transferred still more easily and in a short time.

Further, when the refill container 1 is pushed into the container body 20, the force acting on the pressing portion 11 from the opening edge 22 of the mouth portion 21 of the container body 20 is connected to the outer cylinder portion via the annular pressing portion 11. 9 is transmitted over the entire circumference, the bending deformation of the outer cylinder portion 9 can be stabilized regardless of the position around the container axis O and can be made highly accurate. Thereby, it becomes possible to stabilize the posture of the sealing material 8 when the blade portion 13 is pressed against the sealing material 8, and to make the breakage of the sealing material 8 by the blade portion 13 smooth and reliable. Can do.
Further, by pressing the annular pressing portion 11 against the opening end edge 22 of the mouth portion 21 of the container body 20, communication between the inside and the outside of the container body 20 can be effectively suppressed by the pressing portion 11. Therefore, when the contents F in the refill container 1 are transferred into the container body 20, the contents F can be further suppressed from touching the outside air.

  The inner cylinder portion 10 is inserted inside the pressing portion 11 in the radial direction, and guides the movement of the pressing portion 11 along the container axis O when the outer cylinder portion 9 is bent and deformed. Since it is configured, the posture of the sealing material 8 when the blade portion 13 is pressed against the sealing material 8 can be made more stable, and the breaking of the sealing material 8 by the blade portion 13 can be further smoothed. And it can be assured.
