[0010] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. In this specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant descriptions will be omitted.

[0011] <Overall structure of the container> One embodiment of the present invention relates to a container for holding cosmetic products. First, with reference to Figure 1, the overall configuration of the container according to one embodiment of the present invention will be described.

[0012] Figure 1 is an explanatory diagram showing the external configuration of a container 10 according to one embodiment of the present invention. Figure 2 is an explanatory diagram showing the container 10 with the cap 40 removed. As shown in Figures 1 and 2, the container 10 according to one embodiment of the present invention has 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 housing the inner container 30. The outer container 20 may be translucent, as shown in Figures 1 and 2. A typical example of the material for 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 ceramics. A cap 50 is also detachably attached to the outer container 20. The cap 50 may be attached to the outer container 20 by screwing, fitting, magnetic coupling or other means.

[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 storing cosmetics. The cosmetics stored in the cosmetic container portion 32 may be, for example, creams such as a moisturizing cream, a cream foundation, or an anti-aging care 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 stored in the cosmetic container portion 32 is 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 one embodiment of the present invention, the above-mentioned 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, or polyolefin-based resins.

[0017] The intervening member 40 is an example of a container member that intervenes between the outer container 20 and the inner container 30. The intervening member 40 may be formed of, for example, synthetic resins such as polyester-based, polystyrene-based, or polyolefin-based resins. The detailed configuration of the intervening 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 obtaining the airtightness of the second space 33 for storing cosmetics.

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

[0020] (background) Herein, the background of one embodiment of the present invention will be explained. As mentioned above, the inner container 30 may be made of synthetic resin, but since recycling synthetic resin is currently difficult, there is a concern that the inner container 30 will be discarded after the cosmetic has been used up and removed. In this regard, a method can be considered in which the cosmetic is refilled from the tube container into the inner container 30 when the cosmetic has been used up. However, with this method, the tube container is discarded after use, resulting in a large loss.

[0021] In contrast, in one embodiment of the present invention, the inner container 30 can be made of a metal such as aluminum. In this case, the only material discarded when the inner container 30 is replaced is the sealing material used to seal the inner container 30, which offers significant environmental benefits.

[0022] However, considering that the inner container 30 is formed by deforming an aluminum plate, the design options applicable to the inner container 30 are limited. For example, it is difficult to create undercuts in the inner container 30. Also, if the outer container 20 is made of glass, the dimensional variations of the outer container 20 will be large. Therefore, if the glass outer container 20 and the aluminum inner container 30 are directly fitted together, there is a concern that rattling and foreign matter contamination due to shavings may occur.

[0023] From this perspective, in one embodiment of the present invention, an intervening member 40, for example made of synthetic resin, is provided between the outer container 20 and the inner container 30. Since the intervening member 40 has excellent moldability, it can absorb the tolerances of the glass outer container 20. Furthermore, since the intervening member 40 can be used even after the inner container 30 is replaced, it is also environmentally friendly.

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

[0025] The inventor of this invention has created an embodiment of the present invention, focusing on the above circumstances. This embodiment enables the stable attachment of the intervening member 40 to the outer container 20 and the easy replacement of the inner container 30. The configurations of the outer container 20, inner container 30, and intervening member 40 of the container 10 according to this embodiment will be described in detail below.

[0026] <Outer container 20 configuration> Figure 3 is a cross-sectional view of the outer container 20 according to one embodiment of the present invention along line II shown in Figure 2. As shown in Figure 3, the outer container 20 according to one embodiment of the present invention comprises a lower section 22, a middle section 24, and an upper section 26.

[0027] The lower section 22, the middle section 24, and the upper section 26 each have a cylindrical shape. The hollow regions of the lower section 22, the middle section 24, and the upper section 26 together form a first space 23 for housing the inner container 30. In the example shown in Figure 3, the lower section 22 has a bottom that does not penetrate the first space 23, but the lower section 22 does not have to have a bottom.

[0028] The outer diameter of the middle section 24 is smaller than the outer diameter of the lower section 22. A threaded portion 25 is formed on the outer circumferential surface of the middle section 24, which screws into the inner circumferential surface of the cap 50.

[0029] The upper section 26 is an example of an annular section having an opening that connects 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 circumferential surface of the upper section 26.

[0030] <Configuration of the inner container 30> Figure 4 is a perspective view of the inner container 30 according to one embodiment of the present invention. Figure 5 is a cross-sectional view of the inner container 30 along the line II-II shown in Figure 4. As shown in Figures 4 and 5, the inner container 30 according to one 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 storage section 32 has a bottomed cylindrical shape. The cosmetic storage section 32 forms a second space 33 for storing cosmetics. One or more protrusions 35 are formed on the outer circumferential surface of the cosmetic storage section 32. The one or more protrusions 35 may be, for example, three protrusions formed at equal intervals at the same height.

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

[0033] <Configuration of intervening member 40> Figure 6 is a cross-sectional view of an intervening member 30 according to one embodiment of the present invention. Figure 7 is a cross-sectional perspective view of an intervening member 30 according to one embodiment of the present invention. As shown in Figures 6 and 7, the intervening member 30 according to one embodiment of the present invention comprises an inner cylindrical portion 42, a member flange 44, and an outer cylindrical portion 46.

[0034] The inner cylinder portion 42 is located on the inner circumference side of the outer container 20. Multiple thickened portions 420 and ribs 425 are formed on the inner circumferential surface of the inner cylinder portion 42. The ribs 425 are formed along the vertical direction. The thickened portion 420 has a stepped portion 421 that faces upward and is inclined with respect to the circumferential direction, and a stepped portion 423 that is located on one side of the rib 425 and is formed to face downward. The stepped portion 423 is an example of a first stepped portion, and the stepped portion 421 is an example of a second stepped portion. These multiple thickened portions 420 and ribs 425 contribute to the easy installation of the inner container 30. A detailed explanation follows with reference to Figure 8.

[0035] Figure 8 is an explanatory diagram showing the process of installing the inner container 30. As shown in Figure 8, when a user attempts to install the inner container 30 into the outer container 20 with the intervening member 40 installed, the projection 35 formed on the outer surface of the inner container 30 comes into contact with the stepped portion 421 of the intervening member 40 (position P1). The user then proceeds to insert the inner container 30 by rotating it relative to the intervening member 40 and the outer container 20 so that the projection 35 slides along the stepped portion 421.

[0036] When the projection 35 disengages from the stepped portion 421 and reaches position P2, the user rotates the inner container 30 relative to the intervening member 40 and the outer container 20 so that the projection 35 goes over the rib 425. This causes the projection 35 to reach position P3. At position P3, the upward movement of the projection 35 is restricted because the stepped portion 423 is formed on the upper side, thus preventing the inner container 30 from coming out. Position P3, where the upward movement of the projection 35 is restricted, may be on the counterclockwise or clockwise side of the rib 425 in a plan view when the intervening member 40 is viewed from above, as shown in Figure 8.

[0037] When removing the inner container 30, the user should rotate the inner container 30 relative to the intervening member 40 and the outer container 20 so that the projection 35 overcomes the rib 425, and then pull the inner container 30 out from the intervening member 40 and the outer container 20 after the projection 35 has overcome the rib 425.

[0038] Referring to Figures 6 and 7, we return to the description of the configuration of the intervening member 40. The member flange 44 of the intervening member 40 extends outward from the upper end of the inner cylinder portion 42 (i.e., extends inward from the upper end of the outer cylinder portion 46) and faces the upper end surface of the upper stage portion 26 of the outer container 20. An upper rib 44U is formed on the upper surface of the member flange 44, and a lower rib 44L is formed on the lower surface of the member flange 44. The upper rib 44U and the lower rib 44L are annular ribs. In the example shown in Figures 6 and 7, there is one upper rib 44U and one lower rib 44L, but multiple upper ribs 44U and multiple lower ribs 44L spaced apart in the radial direction may be formed.

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

[0040] <Wearing condition> Next, referring to Figure 9, the state in which the intervening member 40 and the inner container 30 are attached to the outer container 20 will be described.

[0041] Figure 9 is a cross-sectional view showing the state in which the intervening member 40 and the inner container 30 are attached to the outer container 20. In this state, the inner cylindrical 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 cylindrical portion 46 of the intervening member 40 are fitted together. Specifically, the protrusion 27 formed on the outer peripheral surface of the upper portion 26 and the protrusion 47 formed on the inner peripheral surface of the outer cylindrical portion 36 are undercut 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 cylindrical portion 42 of the intervening member 40. The radial length d of this gap is 0.7 mm or more.

[0042] Furthermore, in the state shown in Figure 9, the cosmetic container portion 32 of the inner container 30 is inserted into the inner circumference side of the inner cylindrical portion 42 of the intervening member 40, and the inner container flange 34 of the inner container 30 is in contact with the member flange 44 of the intervening member 40. Also, the peripheral wall portion 36 of the inner container 30 overlaps the outer circumference side of the outer cylindrical 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 cylindrical portion 46.

[0043] <Effects and Effects> According to the embodiment of the present invention described above, various effects and advantages can be obtained. For example, according to the embodiment of the present invention, an intervening member 40 is provided between the outer container 20 and the inner container 30. Even when a glass outer container 20 is used, the intervening member 40 absorbs the effects of the dimensional tolerances of the outer container 20, thus increasing the freedom of the material used for the inner container 30. For example, by making the inner container 30 out of a metal such as aluminum, the amount of synthetic resin waste can be reduced. The intervening member 40 can continue to be 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 disposed of.

[0044] In particular, the length d of the gap between the inner circumferential surface of the outer container 20 and the outer circumferential surface of the inner cylindrical portion 42 of the intervening member 40 is designed to be 0.7 mm or more. When a glass outer container 20 is used, the inner diameter tolerance is expected to be around 0.5 mm, and 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] Furthermore, by providing an intervening member 40 between the outer container 20 and the inner container 30, it is possible to suppress rattling of the inner container 30 even when the dimensional tolerance of the outer container 20 is large. In particular, according to one embodiment of the present invention, an upper rib 44U is formed on the upper surface of the member flange 44, and a lower rib 44L is formed on the lower surface of the member flange 44. The upper rib 44 abuts against the inner container flange 34, and the lower rib 44L abuts against the upper end surface of the upper section 27 of the outer container 20, thereby further suppressing rattling of the inner container 30.

[0046] Furthermore, according to one 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 of attaching and detaching the inner container 30 is improved.

[0047] Furthermore, the peripheral wall portion 36 overlaps the outer peripheral surface side of the outer cylinder portion 46 of the intervening member 40. With this configuration, the outward spreading of the lower end of the outer cylinder portion 46 of the intervening member 40 is suppressed, thereby preventing the fitting between the outer cylinder portion 46 and the outer container 20 from coming undone due to the outward spreading of the lower end of the outer cylinder portion 46. This effect is even more pronounced when the lower end position of the peripheral wall portion 36 is at the same height as the lower end position of the outer cylinder portion 46, or below the lower end position of the outer cylinder portion 46.

[0048] Furthermore, the intervening member 40 according to one embodiment of the present invention has a plurality of thickened portions 420 and ribs 425 formed thereon. A projection 35 formed on the outer circumferential surface of the inner container 30 moves while sliding on the stepped portion 421 by the user's operation, overcoming the ribs 425 and reaching position P3. At position P3, the upward movement of the projection 35 is restricted, thereby preventing the inner container 30 from coming out.

[0049] Furthermore, the position P3 where the upward movement of the projection 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 Figure 8. When the user opens the cap 50, the cap 50 rotates counterclockwise, and the force of this rotation can be transmitted to the inner container 30 that is in contact with 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, the rib 425 is located on the clockwise side, which prevents the projection 35 from going over the rib 425. In other words, it is possible to prevent the inner container 30 from coming off the intervening member 40 unintentionally by the user.

[0050] <Supplement> Although preferred embodiments of the present invention have been described in detail with reference to the attached drawings, the technical scope of the present invention is not limited to these examples. It is clear to any person with ordinary skill in the art of the present invention that various modifications or alterations can be conceived within the scope of the technical idea described in the claims, and these are also understood to naturally fall within the technical scope of the present invention.

[0051] For example, the outer container 20 and the intervening member 40 may have a mechanism to prevent the intervening member 40 from rotating relative to the outer container 20. A specific example of such a mechanism will be described below with reference to Figures 10 and 11.

[0052] Figure 10 is a perspective view of the outer container 20. Figure 11 is a perspective view of the intervening member 40. As shown in Figure 10, anti-rotation ribs 28 may be formed on the outer circumferential surface of the upper portion 26 of the outer container 20 along the vertical direction. These anti-rotation ribs 28 protrude outward from the convex portion 27. Also, as shown in Figure 11, anti-rotation grooves 48 may be formed on the inner circumferential surface of the outer cylindrical portion 46 of the intervening member 40 along the vertical direction. By fitting the anti-rotation ribs 28 of the outer container 20 into the anti-rotation grooves 48 of the intervening member 40, it is possible to prevent the intervening member 40 from rotating relative to the outer container 20. Note that multiple anti-rotation ribs 28 and anti-rotation grooves 48 may be formed at equal intervals in the circumferential direction. Alternatively, anti-rotation grooves may be formed on the outer container 20 side and anti-rotation ribs may be formed on the intervening member 40 side.
