Mode for Carrying Out the Invention

[0010] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

[0011] <<First Embodiment>> <Overall Configuration of the Container> The first embodiment of the present invention relates to a container for storing cosmetics. First, referring to FIG. 1, the overall configuration of the container according to the first embodiment of the present invention will be described.

[0012] FIG. 1 is an explanatory view showing the external configuration of the container 10 according to the first embodiment of the present invention. FIG. 2 is an explanatory view showing the container 10 with the cap 40 removed. As shown in FIGS. 1 and 2, the container 10 according to the first embodiment of the present invention includes an outer container 20, an inner container 30, an intervening member 40, and a cap 50.

[0013] The outer container 20 has a first space for accommodating the inner container 30. As shown in FIGS. 1 and 2, the outer container 20 may have translucency. A typical example of the material of such an outer container 20 is glass. However, the material of the outer container 20 is not limited to glass and may be other materials such as pottery or ceramics. Further, a cap 50 is detachably attached to the outer container 20. The cap 50 may be attached to the outer container 20 in a screwing, fitting, magnetic coupling or other manner.

[0014] As shown in FIG. 2, the inner container 30 includes a cosmetic container portion 32 having a bottomed cylindrical shape. The cosmetic container portion 32 forms a second space 33 for accommodating cosmetics. The cosmetics accommodated in the cosmetic container portion 32 may be, for example, creams such as a moisturizing cream, a cream foundation, and an anti-aging cream. Such a cosmetic container portion 32 is stored in the first space formed in the outer container 20 as shown in FIG. 2. In this specification, the depth direction of the second space 33 (the direction from the opening of the second space 33 toward the bottom of the cosmetic container portion 32) in which the cosmetics are accommodated in the cosmetic container portion 32 may be referred to as the downward direction, and the direction opposite to the downward direction may be referred to as the upward direction. The downward direction is an example of the first direction, and the upward direction is an example of the second direction.

[0015] Further, the inner container 30 has an inner container flange 34 that projects outward from the upper end of the cosmetic container portion 32. The inner container flange 34 is formed in an annular shape. The annular shape is a shape that surrounds a certain region. Here, the inner container flange 34 is formed so as to surround the opening of the second space 33.

[0016] In the first embodiment of the present invention, the above-described inner container 30 is formed of aluminum. However, the material of the inner container 30 is not limited to aluminum, and the inner container 30 may be formed of other metals such as stainless steel, or synthetic resins such as polyester-based, polystyrene-based, and polyolefin-based resins.

[0017] The intermediate member 40 is an example of a container member interposed between the outer container 20 and the inner container 30. The intermediate member 40 may be formed of a synthetic resin such as a polyester-based, polystyrene-based, or polyolefin-based resin, for example. The detailed configuration of the intermediate member 40 will be described later.

[0018] The cap 50 is detachably attached to the outer container 20. In a state where the cap 50 is attached to the outer container 20, the cap 50 and the inner container flange 34 are in close contact with each other, thereby providing airtightness to the second space 33 for storing the cosmetic.

[0019] In such a container 10, when the cosmetic in the inner container 30 runs out, the outer container 20, the intermediate member 40, and the cap 50 can be continuously used by replacing the inner container 30 with a new inner container 30.

[0020] (Background) Here, the background of the first embodiment of the present invention will be described. As described above, the inner container 30 may be formed of a synthetic resin. However, since recycling of synthetic resins is currently difficult, there is a concern that the inner container 30 removed after the cosmetic has run out will be discarded. In this regard, when the cosmetic in the inner container 30 runs out, a method of refilling the inner container 30 with the cosmetic from a tube container can be considered. However, in this method, since the tube container is discarded after use, the loss is large.

[0021] On the other hand, in the first embodiment of the present invention, the inner container 30 can be made of a metal such as aluminum (hereinafter simply referred to as aluminum). In this case, what is discarded when the inner container 30 is replaced is limited to the sealing material used to seal the inner container 30, so there are great environmental advantages.

[0022] However, when the outer container 20 is made of glass or ceramic (hereinafter simply referred to as glass), the variation in the dimensions of the outer container 20 becomes large. For this reason, when the glass outer container 20 and the aluminum inner container 30 are directly fitted together, there is a concern about rattling and the generation of foreign matter contamination due to shaving scraps.

[0023] From such a perspective, in the first embodiment of the present invention, an intervening member 40 formed of, for example, a synthetic resin is provided between the outer container 20 and the inner container 30. Since the intervening member 40 is excellent in moldability, it is possible to absorb the dimensional tolerance of the glass outer container 20. Note that the intervening member 40 formed of a synthetic resin has a higher degree of freedom in shape than the inner container 30 formed by processing a metal plate, and thus is easily applicable to the shape of the outer container 20. Further, since the intervening member 40 can continue to be used even after the inner container 30 is replaced, it is environmentally friendly.

[0024] It is desirable that such an intervening member 40 be stably attached to the outer container 20. Further, it is desirable that the inner container 30 can be easily replaced even when the intervening member 40 is provided.

[0025] The inventor of the present application has created the first embodiment of the present invention from the above viewpoints. The first embodiment of the present invention can achieve stable attachment of the intervening member 40 to the outer container 20 and easy replacement of the inner container 30. Hereinafter, the configurations of the outer container 20, the inner container 30, and the intervening member 40 of the container 10 according to the first embodiment of the present invention will be sequentially described in detail.

[0026] <Configuration of the outer container 20> FIG. 3 is a cross-sectional view taken along line I-I shown in FIG. 2 of the outer container 20 according to the first embodiment of the present invention. As shown in FIG. 3, the outer container 20 according to the first embodiment of the present invention includes a lower stage portion 22, a middle stage portion 24, and an upper stage portion 26.

[0027] The lower stage portion 22, the middle stage portion 24, and the upper stage portion 26 each have a cylindrical shape. The hollow regions of the lower stage portion 22, the middle stage portion 24, and the upper stage portion 26 integrally form a first space 23 for accommodating the inner container 30. In the example shown in FIG. 3, the lower stage portion 22 has a bottom portion that does not penetrate the first space 23, but the lower stage portion 22 may not have a bottom portion.

[0028] The outer diameter of the middle section 24 is smaller than the outer diameter of the lower section 22. A threaded portion 25 that engages with the inner peripheral surface of the cap 50 is formed on the outer peripheral surface of the middle section 24.

[0029] The upper section 26 is an example of an annular portion having an opening leading to the first space 23. The outer diameter of the upper section 26 is smaller than the outer diameter of the middle section 24. A convex portion 27 is continuously formed on the outer peripheral surface of the upper section 26 along the circumferential direction.

[0030] <Configuration of the inner container 30> FIG. 4 is a perspective view of the inner container 30 according to the first embodiment of the present invention. FIG. 5 is a cross-sectional view of the inner container 30 taken along line II-II shown in FIG. 4. As shown in FIGS. 4 and 5, the inner container 30 according to the first embodiment of the present invention has a cosmetic container portion 32, an inner container flange 34, and a peripheral wall portion 36.

[0031] As described above, the cosmetic container portion 32 has a bottomed cylindrical shape. The cosmetic container portion 32 forms a second space 33 for storing cosmetics. One or more protrusions 35 are formed on the outer peripheral surface of the cosmetic container portion 32. The one or more protrusions 35 may be, for example, three protrusions formed at equal intervals at the same height position.

[0032] The inner container flange 34 projects outward from the upper end of the cosmetic container portion 32. The peripheral wall portion 36 extends downward from the outer edge of the inner container flange 34.

[0033] <Configuration of the intervening member 40> FIG. 6 is a cross-sectional view of the intervening member 30 according to the first embodiment of the present invention. FIG. 7 is a cross-sectional perspective view of the intervening member 30 according to the first embodiment of the present invention. As shown in FIGS. 6 and 7, the intervening member 30 according to the first embodiment of the present invention includes an inner cylinder portion 42, a member flange 44, and an outer ring portion 46.

[0034] The inner cylinder part 42 is a part located on the inner peripheral side of the outer container 20. A plurality of thick parts 420 and ribs 425 are formed on the inner peripheral surface of the inner cylinder part 42. The ribs 425 are formed along the vertical direction. The thick part 420 has a stepped part 421 facing upward and inclined with respect to the circumferential direction, and a stepped part 423 located on one side of the rib 425 and formed to face downward. Note that the stepped part 423 is an example of the first stepped part, and the stepped part 421 is an example of the second stepped part. Such a plurality of thick parts 420 and ribs 425 contribute to the easy attachment of the inner container 30. Hereinafter, a specific description will be given with reference to FIG. 8.

[0035] FIG. 8 is an explanatory diagram showing the flow of attaching the inner container 30. As shown in FIG. 8, when a user tries to attach the inner container 30 to the outer container 20 to which the intervening member 40 is attached, a protrusion 35 formed on the outer peripheral surface of the inner container 30 abuts on the stepped part 421 of the intervening member 40 (position P1). Then, the user advances the insertion of the inner container 30 while rotating the inner container 30 with respect to the intervening member 40 and the outer container 20 so that the protrusion 35 slides on the stepped part 421.

[0036] When the protrusion 35 comes off the stepped part 421 and reaches the position P2, the user rotates the inner container 30 with respect to the intervening member 40 and the outer container 20 so that the protrusion 35 gets over the rib 425. As a result, the protrusion 35 reaches the position P3. At the position P3, since the stepped part 423 is formed on the upper side, the upward movement of the protrusion 35 is restricted, so that the inner container 30 is prevented from coming off. That is, a concave part surrounded by the rib 425, the stepped part 423, etc. is formed on the inner peripheral surface of the intervening member 40, and at the position P3, the protrusion 35 is locked by the concave part. The position P3 where the upward movement of the protrusion 35 is restricted may be on the counterclockwise side or the clockwise side of the rib 425 in a plan view when the intervening member 40 is viewed from above as shown in FIG. 8.

[0037] When removing the inner container 30, the user rotates the inner container 30 relative to the intervening member 40 and the outer container 20 so that the protrusion 35 gets over the rib 425, and then the inner container 30 can be pulled out from the intervening member 40 and the outer container 20 after the protrusion 35 gets over the rib 425.

[0038] Returning to the description of the configuration of the intervening member 40 with reference to FIGS. 6 and 7. The member flange 44 of the intervening member 40 extends from the upper end of the inner cylinder portion 42 to the outer peripheral side (that is, extends from the upper end of the outer ring portion 46 to the inner peripheral side), and faces the upper end surface of the upper stage portion 26 of the outer container 20. An upper surface rib 44U is formed on the upper surface of the member flange 44, and a lower surface rib 44L is formed on the lower surface of the member flange 44. The upper surface rib 44U and the lower surface rib 44L are annular ribs. In the example shown in FIGS. 6 and 7, there is one upper surface rib 44U and one lower surface rib 44L each, but a plurality of upper surface ribs 44U spaced apart in the radial direction and a plurality of lower surface ribs 44L spaced apart in the radial direction may be formed.

[0039] The outer ring portion 46 has a cylindrical shape and extends downward from the member flange 44. A convex portion 47 is continuously formed on the inner peripheral surface of the outer ring portion 46 along the circumferential direction.

[0040] <Mounted state> Next, with reference to FIG. 9, the state where the intervening member 40 and the inner container 30 are mounted on the outer container 20 will be described.

[0041] FIG. 9 is a cross-sectional view showing a state in which the intervening member 40 and the inner container 30 are attached to the outer container 20. In this state, the inner cylinder portion 42 of the intervening member 40 is inserted into the first space 23 of the outer container 20, the member flange 44 of the intervening member 40 abuts against the upper end surface of the upper portion 26 of the outer container 20, and the outer peripheral surface of the upper portion 26 of the outer container 20 and the inner peripheral surface of the outer ring portion 46 of the intervening member 40 are fitted together. Specifically, the convex portion 27 formed on the outer peripheral surface of the upper portion 26 and the convex portion 47 formed on the inner peripheral surface of the outer ring portion 46 are undercut and fitted together. Here, a gap is provided between the inner peripheral surface of the outer container 20 and the outer peripheral surface of the inner cylinder portion 42 of the intervening member 40. The length d in the radial direction of the gap is 0.7 mm or more.

[0042] Also, in the state shown in FIG. 9, the cosmetic container 32 of the inner container 30 is inserted into the inner peripheral side of the inner cylinder portion 42 of the intervening member 40, and the inner container flange 34 of the inner container 30 abuts against the member flange 44 of the intervening member 40. Further, the peripheral wall portion 36 of the inner container 30 overlaps the outer peripheral surface side of the outer ring portion 46 of the intervening member 40. The lower end position of the peripheral wall portion 36 is located below the lower end position of the outer ring portion 46.

[0043] <Advantages and effects> According to the first embodiment of the present invention described above, various advantages and effects can be obtained. For example, according to the first embodiment of the present invention, the intervening member 40 is provided between the outer container 20 and the inner container 30. Even when a glass outer container 20 is used, since the intervening member 40 absorbs the influence of the dimensional tolerance of the outer container 20, the degree of freedom in the material used for the inner container 30 is increased. For example, by making the inner container 30 made of a metal such as aluminum, the amount of synthetic resin waste can be reduced. The intervening member 40 can be continuously used even after the inner container 30 is replaced. On the other hand, since the intervening member 40 can be removed from the outer container 20, it can be separated when the container 10 is discarded.

[0044] In particular, the length d of the gap between the inner peripheral surface of the outer container 20 and the outer peripheral surface of the inner cylindrical portion 42 of the intervening member 40 is designed to be 0.7 mm or more. When the glass outer container 20 is used, the inner diameter tolerance is assumed to be about 0.5 mm. The intervening member 40 can be attached to the outer container 20 without being affected by the inner diameter tolerance of the outer container 20.

[0045] Further, by providing the intervening member 40 between the outer container 20 and the inner container 30, it is possible to suppress the occurrence of rattling of the inner container 30 even when the dimensional tolerance of the outer container 20 is large. In particular, according to the first embodiment of the present invention, an upper surface rib 44U is formed on the upper surface of the member flange 44, and a lower surface rib 44L is formed on the lower surface of the member flange 44. By the upper surface rib 44 abutting against the inner container flange 34 and the lower surface rib 44L abutting against the upper end surface of the upper stage portion 27 of the outer container 20, the occurrence of rattling of the inner container 30 can be further suppressed.

[0046] Further, according to the first embodiment of the present invention, the inner container 30 has a peripheral wall portion 36 that extends downward from the outer edge of the inner container flange 34. Since the user can attach and detach the inner container 30 while holding the peripheral wall portion 36, the operability regarding the attachment and detachment of the inner container 30 is improved.

[0047] Furthermore, the peripheral wall portion 36 overlaps the outer peripheral surface side of the outer ring portion 46 of the intervening member 40. According to such a configuration, the lower end of the outer ring portion 46 of the intervening member 40 is suppressed from spreading outward, so that it is possible to prevent the fitting between the outer ring portion 46 and the outer container 20 from being disengaged due to the lower end of the outer ring portion 46 spreading outward. The effect is more remarkably exhibited when the lower end position of the peripheral wall portion 36 is at the same height position as the lower end position of the outer ring portion 46 or lower than the lower end position of the outer ring portion 46.

[0048] Further, in the intervening member 40 according to the first embodiment of the present invention, a plurality of thick portions 420 and ribs 425 are formed. The protrusion 35 formed on the outer peripheral surface of the inner container 30 moves while sliding on the stepped portion 421 by the operation of the user, and reaches the position P3 after overcoming the rib 425. At the position P3, since the upward movement of the protrusion 35 is restricted, it is possible to prevent the inner container 30 from coming off.

[0049] Also, the position P3 where the upward movement of the protrusion 35 is restricted may be on the counterclockwise side of the rib 425 in a plan view when the intervening member 40 is viewed from above as shown in FIG. 8. When the user opens the cap 50, the cap 50 rotates in the counterclockwise direction, and the force of the rotation can be transmitted to the inner container 30 that abuts against the cap 50. At this time, even if the inner cylinder portion 30 tries to rotate in the same counterclockwise direction as the cap 50, since the rib 425 is located on the clockwise side, it is possible to prevent the protrusion 35 from overcoming the rib 425. That is, it is possible to prevent the inner container 30 from unintentionally coming off from the intervening member 40.

[0050] <Supplement to the First Embodiment> Various changes or modifications can be applied to the first embodiment of the present invention described above.

[0051] For example, the outer container 20 and the intervening member 40 may have a mechanism for preventing the intervening member 40 from rotating with respect to the outer container 20. Hereinafter, a specific example of the mechanism will be described with reference to FIGS. 10 and 11.

[0052] FIG. 10 is a perspective view of the outer container 20. FIG. 11 is a perspective view of the intervening member 40. As shown in FIG. 10, a rotation prevention rib 28 may be formed along the vertical direction on the outer peripheral surface of the upper stage portion 26 of the outer container 20. The rotation prevention rib 28 protrudes outward from the convex portion 27. Further, as shown in FIG. 11, a rotation prevention groove 48 may be formed along the vertical direction on the inner peripheral surface of the outer ring portion 46 of the intervening member 40. By fitting the rotation prevention rib 28 of the outer container 20 into the rotation prevention groove 48 of the intervening member 40, it is possible to prevent the intervening member 40 from rotating with respect to the outer container 20. Note that a plurality of rotation prevention ribs 28 and rotation prevention grooves 48 may be formed at equal intervals in the circumferential direction. Further, a rotation prevention groove may be formed on the outer container 20 side, and a rotation prevention rib may be formed on the intervening member 40 side.

[0053] <<Second Embodiment>> Next, a second embodiment of the present invention will be described. The second embodiment has an intervening member 40-2 instead of the intervening member 40 described in the first embodiment. According to the configuration of the intervening member 40-2 according to the second embodiment of the present invention, in addition to the effects described in the first embodiment, an effect that the intervening member 40-2 can be more easily removed from the outer container 20 is obtained. Therefore, when the container 10 is discarded, the user can easily separate it. Hereinafter, the configuration of the intervening member 40-2 according to the second embodiment of the present invention will be described.

[0054] <Configuration> FIG. 12 is a side view of the intervening member 40-2 according to the second embodiment of the present invention. FIG. 13 is a diagram schematically showing the lower surface of the intervening member 40-2 according to the second embodiment of the present invention. As shown in FIGS. 12 and 13, the intervening member 40-2 according to the second embodiment has an outer ring portion 49 formed so as to extend downward from the member flange 44.

[0055] The slit S is formed at one or more circumferential positions of the outer ring portion 49. In other words, the outer ring portion 49 has two or more circumferential wall portions separated from each other by the slit S. These circumferential wall portions extend downward from the member flange 44. In the examples shown in FIGS. 12 and 13, four slits S are formed at equal intervals in the circumferential direction in the outer ring portion 49. However, the number of the slits S is not limited to four, and the number of the slits S may be other numbers such as one, two, three, or five or more. Also, the intervals between the respective slits S do not have to be equal intervals.

[0056] FIG. 14 is a partially enlarged cross-sectional view of the container 10. In FIG. 14, the fitting margin d1 between the convex portion 27 of the upper stage portion 26 of the outer container 20 and the convex portion 47 of the outer ring portion 49 of the intervening member 40-2 is shown. The fitting margin d1 is the length in the radial direction between the tip position of the convex portion 27 and the tip position of the convex portion 47 (in other words, the amount of displacement of the outer ring portion 49 in the radial outer direction required for the convex portion 47 to overcome the convex portion 27). Also, the length d2 (first length) of the interval between the inner peripheral surface of the circumferential wall portion 36 of the inner container 30 and the outer peripheral surface of the outer ring portion 49 of the intervening member 40-2 in a state where the inner container 30 is housed in the outer container 20 without being biased in plan view (in other words, so that the central axis of the inner container 30 coincides with the central axis of the outer container 20) is shown, and the length d3 (second length) of the interval between the outer peripheral surface of the cosmetic housing portion 32 of the inner container 30 and the inner peripheral surface of the inner cylinder portion 42 of the intervening member 40-2 is shown. The length d3 may be, in other words, the length by which the inner container 30 can move in the radial direction from a state where the inner container 30 is housed in the outer container 20 without being biased in plan view.

[0057] The fitting margin d1 between the convex portion 27 of the upper stage portion 27 of the outer container 20 and the convex portion 47 of the outer ring portion 49 of the intervening member 40-2 is larger than the length d2 of the interval between the inner peripheral surface of the circumferential wall portion 36 of the inner container 30 and the outer peripheral surface of the outer ring portion 49 of the intervening member 40-2. Further, the fitting margin d1 is larger than the total length of the length d2 and the length d3 of the interval between the outer peripheral surface of the cosmetic housing portion 32 of the inner container 30 and the inner peripheral surface of the inner cylinder portion 42 of the intervening member 40-2.

[0058] <Function and effect> According to the second embodiment of the present invention described above, various operational effects can be obtained. For example, in the second embodiment of the present invention, the slit S is formed at one or more circumferential positions of the outer ring portion 49. According to such a configuration, the outer ring portion 49 is more likely to bend so that the tip on the lower side of the outer ring portion 49 faces outward as compared with the case where the slit S is not formed in the outer ring portion 49. Therefore, in a state where the inner container 30 is removed from the intervening member 40-2, it becomes easier to further remove the intervening member 40-2 from the outer container 20. In a mode where the peripheral wall portion 36 is not provided on the inner container 30, the above-described operational effects can also be obtained even in a state where the inner container 30 is installed on the intervening member 40-2.

[0059] Also, in the second embodiment of the present invention, the fitting allowance d1 between the convex portion 27 of the upper stage portion 26 of the outer container 20 and the convex portion 47 of the outer ring portion 49 of the intervening member 40-2 is larger than the length d2 of the interval between the inner peripheral surface of the peripheral wall portion 36 of the inner container 30 and the outer peripheral surface of the outer ring portion 49 of the intervening member 40-2. According to such a configuration, when the outer ring portion 49 abuts against the peripheral wall portion 36 of the inner container 30, the tip on the lower side of the outer ring portion 49 is difficult to move outward by a length of d2 or more. Therefore, in a state where the inner container 30 is accommodated, it is possible to suppress the occurrence of the fitting between the intervening member 40-2 and the outer container 20 being unexpectedly disengaged.

[0060] Furthermore, the fitting allowance d1 is larger than the total length of the length d2 and the length d3 of the interval between the outer peripheral surface of the cosmetic container portion 32 of the inner container 30 and the inner peripheral surface of the inner cylinder portion 42 of the intervening member 40-2. According to such a configuration, even when the inner container 30 is movable in the radial direction and there is a deviation in the position of the inner container 30, the length of the interval between the inner peripheral surface of the peripheral wall portion 36 of the inner container 30 and the outer peripheral surface of the outer ring portion 49 of the intervening member 40-2 does not exceed the fitting allowance d1. Therefore, it is possible to more reliably suppress the fitting between the intervening member 40-2 and the outer container 20 from being unexpectedly disengaged.

[0061] <Modification Example of the Second Embodiment> FIG. 15 is an external view of the outer container 20 according to a modified example applicable to the second embodiment. As shown in FIG. 15, a convex portion 29 may be formed on the outer peripheral surface of the upper stage portion 26 of the outer container 20. The length d4 of the convex portion 29 in the circumferential direction is equal to or less than the length of at least any one of the slits S formed in the outer ring portion 49 in the circumferential direction. Therefore, the convex portion 29 fits into any one of the slits S. According to such a configuration, it is possible to prevent the rotation of the intervening member 40-2 and thus the inner container 30 with respect to the outer container 20. Although one convex portion 29 is shown in FIG. 15, a plurality of convex portions 29 may be formed on the outer peripheral surface of the upper stage portion 26.

[0062] Furthermore, it is also possible to use the convex portion 29 to position the intervening member 40-2 with respect to the outer container 20. For example, the number of the convex portions 29 and the number of the slits S in the outer ring portion 49 of the intervening member 40-2 may be designed to be one. According to such a configuration, the position of the intervening member 40-2 with respect to the outer container 20 is uniquely determined. Alternatively, as shown in FIG. 16, the number of the slits S having a length in the circumferential direction greater than the length d4 of the convex portion 29 may be designed to be one.

[0063] FIG. 16 is a bottom view of the intervening member 40-2 according to the modified example. In the example shown in FIG. 16, the lengths of the slits S2 to S4 in the circumferential direction are the same, and the length of the slit S1 in the circumferential direction is longer than those of the other slits S2 to S4. Further, the length of the slit S1 in the circumferential direction is equal to or greater than the length d4 of the convex portion 29, and the lengths of the other slits S2 to S4 in the circumferential direction are less than the length d4 of the convex portion 29.

[0064] According to the above configuration, since the slit S into which the convex portion 29 can be fitted is limited to the slit S1, the ease of removal of the intervening member 40-2 is improved, and the positioning of the intervening member 40-2 with respect to the outer container 20 is realized.

[0065] As another example, a plurality of convex portions 29 may be formed on the outer container 20 at non-uniform intervals, and a plurality of slits S may also be formed on the outer ring portion 49 as gaps having sizes corresponding to the plurality of convex portions 29 respectively (in other words, the peripheral wall portions of the outer ring portion 49 sandwiched by the slits S have sizes corresponding to the intervals of the plurality of convex portions 29). Even with such a configuration, since the slits S into which the respective convex portions 29 are fitted are determined, positioning of the intervening member 40-2 with respect to the outer container 20 is achieved.

[0066] <<Supplementary Note>> As described above, the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the technical scope of the present invention is not limited to such examples. It is obvious that those having ordinary knowledge in the technical field of the present invention can conceive of various modification examples or correction examples within the scope of the technical idea described in the claims, and it is naturally understood that these also belong to the technical scope of the present invention.

[0067] For example, in the second embodiment, an example where the slit S does not reach the member flange 44 of the intervening member 40-2 has been described, but the slit S may reach the member flange 44. That is, the slit S may also be formed at one or more circumferential positions of the member flange 44. According to such a configuration, in a state where the inner container 30 is removed from the intervening member 40-2, it becomes easier to remove the intervening member 40-2 from the outer container 20.

[0068] Also, one or more ribs spaced apart from each other in the vertical direction may be formed along the circumferential direction on the outer peripheral surface of the outer ring portion 49 of the intervening member 40-2. According to such a configuration, when a user's finger catches on the rib, it becomes easier for the user to remove the intervening member 40-2 from the outer container 20.
