  In the refill container 1 configured as described above, the lid body 8 is attached to the storage container 10 which is the storage body 7 storing the inner container 5 on either or both of the inner surface of the cylindrical wall portion 14 of the lid body 8 and the inner container 5. A contact portion 60 is provided in which the inner surface of the cylindrical wall portion 14 of the lid body 8 and the outer surface of the body portion 19 of the inner container 5 housed in the lid body 8 come into contact with each other.

  In this example, a contact portion 60 is provided on the inner surface of the cylindrical wall portion 14 of the lid 8. The contact portion 60 on the inner surface of the cylindrical wall portion 14 of the lid 8 is formed by a plurality of ribs 61 extending in the vertical direction in this example. The height of the rib 61 is set to a height at which the rib 61 contacts the outer surface of the body portion 19 of the inner container 5 with a predetermined pressing force.

The resistance force of the contact portion 60 provided on the inner surface of the cylindrical wall portion 14 of the lid 8 that contacts the outer surface of the body portion 19 of the inner container 5 is as follows.
The resistance force of the contact portion 60 when the inner container 5 accommodated in the lid body 8 is pulled out from the opening portion 62 of the lid body 8 is X1, and the lower limit resistance that the inner container 5 does not fall from the opening portion of the lid body by its own weight. When the upper limit resistance force that can be pulled out from the opening 62 of the lid body 8 is X3 when the force is X2, and the inner container 5 accommodated in the lid body 8 is exhausted, the inside of the lid body 8 The resistance force X1 when pulling out the stored inner container 5 from the opening 62 of the lid 8 is set within the range of the following calculation formula.

Further, the upper limit resistance force X3 is calculated as a resistance force that allows the inner container 5 housed in the lid body 8 to be pulled out from the opening 62 of the lid body 8 with the contents exhausted. It is preferred that The resistance force that can be pulled out without difficulty refers to a resistance force that allows an adult to pick up the inner container 5 housed in the lid 8 and easily pull it out without being particularly aware of the strong force.

以上の結果から、無理なく引き出せる上限抵抗力Ｘ３を下記にように算出した。
上限抵抗力Ｘ３＝１．５ｋｇｆ The upper limit resistance force X3 was calculated as follows.
<Evaluation of resistance X>
By changing the height of the rib 61 serving as the contact portion 60 provided on the inner surface of the cylindrical wall portion 14 of the lid 8, the resistance force when the inner container 5 is pulled out from the opening 62 of the lid 8 is changed, The resistance at the time of pulling out was evaluated by sensuality. Further, the resistance force at that time was measured using a push-pull gauge.
Sensory evaluation criteria ◎ It can be pulled out very easily.
〇 Can be pulled out without difficulty.
△ Can be pulled out but has strong resistance.
× Cannot be pulled out.
The evaluation results are shown in Table 1.

From the above results, the upper limit resistance force X3 that can be pulled out without difficulty was calculated as follows.
Upper limit resistance X3 = 1.5kgf

  The resistance force X1, the lower limit resistance force X2, and the upper limit resistance force X3 are controlled by the force at which the cylindrical wall portion 14 of the lid body 8 and the body portion 19 of the inner container 5 push each other at the contact portion 60 and the contact portion 60. This is done by controlling the coefficient of friction.

  In this example, the contact portion 60 is formed by the rib 61, but is not limited thereto. For example, a projection (not shown) formed by embossing may be formed on the inner surface of the cylindrical wall portion 14 of the lid body 8 to form the contact portion 60. Alternatively, as shown in FIG. It is also possible to form a concave bent portion 63 by bending a part of the concave portion 14 and use the concave bent portion 63 as the contact portion 60. The pressing force in the contact portion 60 is controlled by the height, shape, contact area, etc. of the rib 61 or the embossed or recessed curved portion 63.

  The friction coefficient in the contact portion 60 is controlled by processing the surface of the inner surface of the cylindrical wall portion 14 of the lid 8 (for example, mat, mirror, etc.), applying an anti-slip agent, etc., or rubber, silicon. It is controlled by providing a layer such as.

Refilling of the liquid contents in the refill container 1 configured as described above is performed as follows.
The refilling operation of the liquid contents in the refill container 1 includes the operation of storing the inner container 5 in the storage container 10 serving as the storage body 7 in the refill container 1 and the operation of taking out the inner container 5 stored in the storage container 10 from the storage container 10. Divided into

In the operation of storing the inner container 5 in the storage container 10, first, the inner container 5 is stored in the storage container 10.
Next, the cylindrical wall portion 14 of the lid 8 is fitted to the outer periphery of the storage container 10 in which the inner container 5 is stored, and the storage port 6 of the storage container 10 is closed. In this example, in the process of closing the storage port 6 of the storage container 10, the rib 61 serving as the contact portion 60 provided on the inner surface of the cylindrical wall portion 14 of the lid 8 contacts the outer surface of the body portion 19 of the inner container 5. While moving in the closing direction.

  Further, in the process of closing the storage port 6 of the storage container 10, the upper surface portion 2 of the inner container 5 in which the suction pipe 18 disposed on the lower surface side of the top plate portion 13 of the lid 8 is stored in the storage container 10. The film 3 is broken and inserted into the inner container 5 through the suction port 4.

  In this way, the storage port 6 of the storage container 10 is closed by the lid body 8, and the operation of storing the inner container 5 in the storage container 10 is completed. At this time, the inner container 5 stored in the storage container 10 is in a state in which the outer surface of the trunk portion 19 is in contact with the rib 61 that becomes the contact portion 60 provided on the inner surface of the cylindrical wall portion 14 of the lid body 8. (See FIG. 7).

When the liquid content in the inner container 5 stored in the storage container 10 is exhausted, the lid 8 is removed from the storage container 10 and the inner container 5 in which the content is exhausted is taken out of the storage container 10.
In taking out the inner container 5 from the storage container 10, the lid 8 is pulled up.

  At this time, the resistance force of the contact portion 60 provided on the inner surface of the cylindrical wall portion 14 of the lid body 8 that contacts the outer surface of the trunk portion 19 of the inner container 5 causes the inner container 5 accommodated in the lid body 8 to The resistance force of the contact portion 60 when it is pulled out from the opening 62 of the lid body 8 is X1, and the lower limit resistance force that the inner container 5 does not fall from the opening portion of the lid body due to its own weight is X2, and is accommodated in the lid body 8. When the upper limit resistance that can be pulled out from the opening 8 of the lid 8 with the contents exhausted is X3, the inner container 5 accommodated in the lid 8 is opened to the lid 8. Since the resistance force X1 when pulling out from the portion 62 is set within the range of the calculation formula X2 ≦ X1 ≦ X3, when the lid body 8 is removed from the storage container 10 housing the inner container 5, the inside of the lid body 8 The inner container 5 housed in the container is taken out of the storage container 10 together with the lid 8, and the lid 8 is opened. Also the part 62 toward the bottom, the inner container 5 does not fall from the lid 8 (see FIG. 8.).

Since the removal of the inner container 5 from the lid 8 is X1 ≦ X3, the inner container 5 exposed from the opening 62 of the lid 8 is picked and reliably pulled out from the opening 62 of the lid 8. (See FIG. 9).
In this way, the operation of taking out the inner container 5 stored in the storage container 10 is completed.

  If the lower limit resistance X2 is calculated for the inner container 5 with the contents exhausted, the lid 8 is removed when the cover 8 is removed from the storage container 10 after the contents are exhausted. The inner container 5 housed inside can be reliably removed from the housing container 10 together with the lid 8.

  Further, if the lower limit resistance X2 is calculated in the inner container 5 in a state where the contents are fully accommodated, the lower limit resistance force X2 is determined from the storage container 10 in a state where the contents are fully accommodated in the inner container 5. When the lid body 8 is removed, the inner container 5 accommodated in the lid body 8 can be reliably removed from the storage container 10 as a unit with the lid body 8.

  Further, the upper limit resistance force X3 is calculated as a resistance force that allows the inner container 5 to be pulled out from the opening 62 of the lid body 8 with the contents exhausted from the inner container 5 housed in the lid body 8. As a result, the inner container 5 whose contents have been exhausted can be easily and reliably pulled out from the opening 62 of the lid 8.

  In this example, the contact portion 60 where the inner surface of the cylindrical wall portion 14 of the lid body 8 and the outer surface of the inner container 5 accommodated in the lid body 8 are in contact with the inner surface of the cylindrical wall portion 14 of the lid body 8. Although the contact part 60 is provided, as illustrated in FIG. 11, an annular protrusion 64 may be formed around the outer surface of the body part 19 of the inner container 5 to form the contact part 60, or illustrated in FIG. 12. As described above, an annular protrusion 64 is formed around the outer surface of the body portion 19 of the inner container 5, and an annular protrusion 65 that contacts the annular protrusion 64 is formed around the inner surface of the cylindrical wall portion 14 of the lid 8. The contact portion 60 may be used.

  The contact portion 60 where the inner surface of the cylindrical wall portion 14 of the lid body 8 and the outer surface of the inner container 5 housed in the lid body 8 come into contact is a rib 61 formed on the inner surface of the cylindrical wall portion 14 of the lid body 8. Or an annular protrusion 64 formed around the outer surface of the barrel 19 of the inner container 5, and an inner periphery of the cylindrical wall portion 14 of the lid 8 and the annular protrusion 64 formed around the outer surface of the barrel 19 of the inner container 5. Although not shown in the figure, the annular protrusion 65 formed on the inner surface of the lid body 8 is contacted with the inner surface of the cylindrical wall portion 14 of the lid body 8 and the outer surface of the container 5 to form a contact portion 60, and the cylindrical wall portion 14 of the lid body 8. By controlling the friction coefficient only by the material of the inner container 5, the resistance force of the resistance force X 1, the lower limit resistance force X 2, and the upper limit resistance force X 3 may be controlled.

Further, in this example, the storage body 7 is a cylindrical storage container 10 that opens the storage port 6 at the top. However, the storage body 7 is not limited to this, and as shown in FIG. A pedestal that accommodates the inner container 5 inside the support frame portion 58, comprising a support frame portion 58 in which a plurality of support pieces 57 extending along the outer surface of the body portion 19 of the inner container 5 are spaced apart from each other. It may be configured in a shape.
Further, in this example, the storage body 7 has the storage opening 6 for storing the inner container 5 opened at the top, but is not limited to this, and the storage opening 6 is open at the side. May be.
