[Figure 4] FIG. 4 is an enlarged view of part B in FIG. 3. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] As shown in FIGS. 1 and 2, in the first embodiment of the present invention, a refill container 1 comprises a container body 2, a refill container 3 that can be attached to the container body 2 by rotating it about a central axis O, and a top lid 4 that can be attached to and detached from the container body 2 by rotating it about the central axis O. The refill container 3 comprises a refill container body 3a and a high-friction elastic member 5. The top lid 4 comprises a lid body 4a and a sheet-like packing 4b. The materials of the container body 2, refill container body 3a, and lid body 4a are not particularly limited and may be made of resin, for example. The container body 2, refill container body 3a, and lid body 4a are each integrally molded. However, the container body 2, refill container body 3a, and lid body 4a are not limited to these, and may each be formed by assembling multiple members.

[0015] In this application, the vertical direction refers to the vertical direction when the refill container 1 is in an upright position (a position in which the top lid 4 is located on the upper side), and in this embodiment, it corresponds to the direction along the central axis O. In this embodiment, the direction along a line perpendicular to the central axis O is also referred to as the radial direction, and the direction going around the central axis O is also referred to as the circumferential direction.

[0016] The container body 2 has a bottom 2a and an outer peripheral portion 2b extending upward from the bottom 2a. The bottom 2a is formed by a bottom wall 6. The outer peripheral portion 2b has an outer peripheral upper end portion 2c, an outer peripheral intermediate portion 2d, and an outer peripheral lower portion 2e facing downward, in this order. The outer peripheral upper end portion 2c is formed by a cylindrical wall 7 centered on the central axis O. The outer peripheral surface of the outer peripheral intermediate portion 2d has a larger diameter than the outer peripheral upper end portion 2c. The outer peripheral intermediate portion 2d is also formed by an annular intermediate top wall 8 extending radially outward from the lower end of the cylindrical wall 7, a cylindrical intermediate outer wall 9 hanging down from the outer peripheral edge of the intermediate top wall 8 and centered on the central axis O, and an intermediate inner wall 10 extending downward from the lower end of the cylindrical wall 7. The outer peripheral lower portion 2e is formed by an annular lower top wall 11 extending radially outward from the lower end of the intermediate outer wall 9, a cylindrical lower outer wall 12 hanging down from the outer peripheral edge of the lower top wall 11 and centered on the central axis O, and a lower inner wall 13 extending downward from the lower end of the intermediate inner wall 10. The lower end of the lower inner wall 13 is continuous with the outer peripheral edge of the bottom wall 6. Note that although the lower outer wall 12 is cylindrical, it may have a configuration other than a cylindrical shape, such as a rectangular cylindrical shape, for example.

[0017] The refill container body 3a has a content storage section 14, a mouth flange 15, and a depending tubular section 16. The content storage section 14 is concave and has a mouth opening 17 at its upper end. The content storage section 14 is formed by a storage section bottom wall 14a and a storage section outer peripheral wall 14b that extends upward from the outer peripheral edge of the storage section bottom wall 14a and has a cylindrical shape centered on the central axis O. The mouth flange 15 has an annular flange shape that extends radially outward from the outer peripheral upper end 2c of the content storage section 14, i.e., the upper end of the storage section outer peripheral wall 14b. The depending tubular section 16 hangs down from the outer peripheral edge of the mouth flange 15 and has a cylindrical shape centered on the central axis O.

[0018] High-friction elastic member 5 is held between the upper end of the inner circumferential surface of hanging tubular portion 16 and the upper end of the outer circumferential surface of storage portion outer circumferential wall 14b, and forms an annular shape centered on central axis O. Outer circumferential upper end 2c and hanging tubular portion 16 are rotatable via first threaded portion 18. That is, refill container 3 can be replaced with respect to container body 2 by rotation via first threaded portion 18. First threaded portion 18 is formed, for example, by a continuous or intermittent male thread portion provided on outer circumferential upper end 2c and a continuous or intermittent female thread portion provided on hanging tubular portion 16. When refill container 3 is completely screwed into container body 2 via first threaded portion 18 and installation of refill container 3 is complete, rotation of hanging tubular portion 16 and container body 2 relative to each other is restricted via stopper portions 19 that can be overcome on both circumferential sides by elastic deformation. Stopper portion 19 is formed by an uneven shape provided on the lower end of hanging tubular portion 16 and an uneven shape provided at the boundary between the outer peripheral surface of outer peripheral upper end 2c and the upper surface of outer peripheral intermediate portion 2d. Note that stopper portion 19 is not limited to this, and may be formed, for example, by an uneven shape provided on the lower end of hanging tubular portion 16 and an uneven shape provided on the lower end of the outer peripheral surface of outer peripheral upper end 2c, or by an uneven shape provided on the lower end of hanging tubular portion 16 and an uneven shape provided on the upper surface of outer peripheral intermediate portion 2d. When attachment of refill container 3 is complete, the lower surface of mouth flange 15 of refill container 3 and the upper surface of outer peripheral upper end 2c (cylindrical wall 7) of container body 2 come into contact with each other via high-friction elastic member 5, and as a result, rattle of refill container 3 in the up-and-down direction relative to container body 2 is suppressed.

[0019] The contents stored in the contents storage section 14 are not particularly limited, and may be, for example, cosmetics.

[0020] The top lid 4 has a lid top portion 20 and a lid outer peripheral portion 21 that hangs down from the lid top portion 20. The lid top portion 20 is formed by a top wall 22 of the lid main body 4a and a sheet-like gasket 4b that is disposed along the underside of the top wall 22 and held by the lid main body 4a. The sheet-like gasket 4b covers the mouth opening 17 when the top lid 4 is closed. The lid main body 4a has the top wall 22 and the lid outer peripheral portion 21. The lid outer peripheral portion 21 hangs down from the top wall 22 and is formed by a tubular lid outer peripheral wall 23 that is centered on the central axis O. The lid outer peripheral portion 21 (lid outer peripheral wall 23) and the outer peripheral intermediate portion 2d (intermediate outer wall 9) are rotatable via a second screw portion 24. In other words, the top lid 4 can be attached to and detached from the container main body 2 by rotating it via the second screw portion 24. The second screw portion 24 is formed, for example, by a continuous or intermittent female thread portion provided on the lid outer peripheral portion 21 (lid outer peripheral wall 23) and a continuous or intermittent male thread portion provided on the outer peripheral intermediate portion 2d (intermediate outer wall 9). The top lid 4 is detachable from the container body 2 when the refill container 3 has been attached.

[0021] The direction in which the top lid 4 is rotated relative to the container body 2 in order to close the top lid 4, i.e., to attach the top lid 4 to the container body 2, coincides with the direction in which the refill container 3 is rotated relative to the container body 2 in order to attach the refill container 3 to the container body 2. In other words, the top lid 4 and the refill container 3 are each attached to the container body 2 by rotating them in one circumferential direction (for example, clockwise) when viewed from above, and are removed from the container body 2 by rotating them in the other circumferential direction when viewed from above.

[0022] When the top lid 4 is closed, a seal 25 is formed by an annular protrusion centered on the central axis O at the contact point between the upper surface of the mouth flange 15 of the refill container 3 and the lid top 20 (sheet-like packing 4b) of the top lid 4, and the lower surface of the mouth flange 15 of the refill container 3 contacts the upper surface of the outer circumferential upper end 2c (cylindrical wall 7) of the container body 2 via the high-friction elastic member 5. Therefore, when the top lid 4 is opened, the frictional force acting between the top lid 4 and the refill container 3 via the seal 25 is suppressed, and the frictional force between the refill container 3 and the container body 2 is increased by the high-friction elastic member 5, thereby preventing the refill container 3 from rotating together with the container body 2. As a result, the attachment state of the refill container 3 to the container body 2 can be prevented from becoming unstable. The annular protrusion forming the seal 25 is provided on the upper surface of the mouth flange 15.

[0023] The high-friction elastic member 5 generates a frictional force higher than that between at least one of the lower surface of the mouth flange 15 and the upper surface of the outer circumferential upper end portion 2c (cylindrical wall 7) of the container body 2. The high-friction elastic member 5 is preferably formed from an elastic material that generates such a high frictional force, and examples of such elastic materials include silicone.

[0024] Furthermore, in this embodiment, when the top lid 4 is closed, the seal portion 25 is located directly above the contact point between the high-friction elastic member 5 and the container body 2 (the upper surface of the outer circumferential upper end portion 2c). This allows for good vertical compression force transmission to the seal portion 25, ensuring sealing performance while allowing the radial width of the annular protrusion forming the seal portion 25 to be set narrower. As a result, the frictional force acting between the top lid 4 and the refill container 3 via the seal portion 25 when the top lid 4 is opened can be further reduced.

[0025] In this embodiment, the stopper portion 19 can enhance the effect of suppressing co-rotation.

[0026] Next, a second embodiment of the present invention will be described.

[0027] As shown in Figures 3 and 4, the refill container 1 of the second embodiment of the present invention has the same configuration as that of the first embodiment, except for the top lid 4. In this embodiment, the top lid 4 has an outer lid member 4c and an inner lid member 4d that is placed inside the outer lid member 4c and held by the outer lid member 4c. The inner lid member 4d is formed by an inner outer peripheral member 26, an inner inner peripheral member 27, and an elastic ring 28. The materials of the outer lid member 4c, the inner outer peripheral member 26, and the inner inner peripheral member 27 are not particularly limited, and they may be made of resin, for example.

[0028] The top lid 4 has a lid top portion 20 and a lid outer peripheral portion 21 that hangs down from the lid top portion 20. The lid top portion 20 is formed by an outer top wall 29 of the outer lid member 4c, an inner inner peripheral member 27, an elastic ring 28, and a top wall portion 26a of the inner outer peripheral member 26. The inner inner peripheral member 27 covers the mouth opening 17 when the top lid 4 is closed. The outer lid member 4c has an outer top wall 29 and an outer peripheral wall 30. The inner outer peripheral member 26 has an annular top wall portion 26a centered on the central axis O, and a cylindrical outer peripheral wall portion 26b that hangs down from the outer peripheral edge of the top wall portion 26a and is centered on the central axis O. The lid outer peripheral portion 21 is formed by the outer peripheral wall 30 of the outer lid member 4c and the outer peripheral wall portion 26b of the inner outer peripheral member 26.

[0029] The outer surface of the outer wall portion 26b of the inner outer member 26 is attached and held by fitting to the inner surface of the outer peripheral wall 30 of the outer cover member 4c in a state in which rotation is restricted to one circumferential side and the other circumferential side when viewed from above.

[0030] The top wall portion 26a of the inner outer peripheral member 26 is formed by a lower wall portion 31, a stepped wall portion 32, and an upper wall portion 33, each of which has an annular shape centered on the central axis O. The upper wall portion 33 is offset upward in a step-like manner relative to the lower wall portion 31, and the outer peripheral edge of the upper wall portion 33 is connected to the inner peripheral edge of the lower wall portion 31 via the stepped wall portion 32. The inner inner peripheral member 27 is formed by an inner inner peripheral top wall 27a, a fitting tube 27b, and a regulating tube 27c. The inner inner peripheral top wall 27a is circular and centered on the central axis O in a top view. The fitting tube 27b extends upward from the inner inner peripheral top wall 27a and is cylindrical and centered on the central axis O. The outer peripheral surface of the fitting tube 27b engages with the inner peripheral edge of the upper wall portion 33 so that the inner inner peripheral member 27 is held by the inner outer peripheral member 26 so as to be displaceable in the vertical direction. The restricting tube 27c extends upward from the inner inner circumferential top wall 27a radially outward of the fitting tube 27b and radially inward of the outer circumferential edge of the inner inner circumferential top wall 27a, and has a cylindrical shape centered on the central axis O. An annular elastic ring 28 centered on the central axis O is disposed and held between the boundary between the outer circumferential edge of the inner inner circumferential top wall 27a and the restricting tube 27c, and between the boundary between the upper wall portion 33 and the stepped wall portion 32.

[0031] The lid outer peripheral portion 21 and the outer peripheral intermediate portion 2d (intermediate outer wall 9) are rotatable via the second screw portion 24. In other words, the top lid 4 can be attached to and detached from the container body 2 by rotating via the second screw portion 24. The second screw portion 24 is formed, for example, by a continuous or intermittent female thread portion provided on the lid outer peripheral portion 21 (outer peripheral wall portion 26b of the inner outer peripheral member 26) and a continuous or intermittent male thread portion provided on the outer peripheral intermediate portion 2d (intermediate outer wall 9). The top lid 4 can be attached to and detached from the container body 2 when the refill container 3 has been attached.

[0032] The direction in which the top lid 4 is rotated relative to the container body 2 in order to close the top lid 4, i.e., to attach the top lid 4 to the container body 2, coincides with the direction in which the refill container 3 is rotated relative to the container body 2 in order to attach the refill container 3 to the container body 2. In other words, the top lid 4 and the refill container 3 are each attached to the container body 2 by rotating them in one circumferential direction (for example, clockwise) when viewed from above, and are removed from the container body 2 by rotating them in the other circumferential direction when viewed from above.

[0033] When the top lid 4 is closed, a seal 25 is formed by an annular protrusion centered on the central axis O at the contact point between the upper surface of the mouth flange 15 of the refill container 3 and the lid top 20 (inner circumferential member 27) of the top lid 4, and the lower surface of the mouth flange 15 of the refill container 3 contacts the upper surface of the outer circumferential upper end 2c (cylindrical wall 7) of the container body 2 via the high-friction elastic member 5. Therefore, when the top lid 4 is opened, the frictional force acting between the top lid 4 and the refill container 3 via the seal 25 is suppressed, and the frictional force between the refill container 3 and the container body 2 is increased by the high-friction elastic member 5, thereby preventing the refill container 3 from rotating together with the container body 2. As a result, the attachment state of the refill container 3 to the container body 2 can be prevented from becoming unstable. The annular protrusion forming the seal 25 is provided on the lower surface of the inner circumferential member 27.

[0034] Furthermore, in this embodiment, when the top lid 4 is closed, the seal portion 25 is located directly above the contact point between the high-friction elastic member 5 and the container body 2 (the upper surface of the outer circumferential upper end portion 2c). Therefore, the vertical compressive force from the high-friction elastic member 5 can be effectively transmitted to the seal portion 25, and the radial width of the annular protrusion forming the seal portion 25 can be set to be narrower while ensuring sealing performance. As a result, the frictional force acting between the top lid 4 and the refill container 3 via the seal portion 25 when the top lid 4 is opened can be further reduced.

[0035] Furthermore, in this embodiment, when the top lid 4 is closed, the upper surface of the inner inner circumferential member 27 and the lower surface of the inner outer circumferential member 26 come into contact via the elastic ring 28, and the seal portion 25 is located directly below the contact point between the elastic ring 28 and the inner outer circumferential member 26 (the lower surface of the upper wall portion 33). Therefore, the vertical compressive force from the elastic ring 28 can be effectively transmitted to the seal portion 25, and the radial width of the annular protrusion forming the seal portion 25 can be set even narrower. As a result, the frictional force acting between the top lid 4 and the refill container 3 via the seal portion 25 when the top lid 4 is opened can be further reduced.

[0036] In this embodiment, the stopper portion 19 can enhance the effect of suppressing co-rotation.

[0037] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0038] Therefore, the replacement container 1 of the above-mentioned embodiment can be modified as long as it is a replacement container 1 that has a container body 2, a refill container 3 that can be attached to the container body 2 by rotating it, and a top lid 4 that can be attached and detached to the container body 2 by rotating it, and when the top lid 4 is closed, a seal portion 25 is formed by an annular protrusion at the contact portion between the upper surface of the mouth flange 15 of the refill container 3 and the top lid 4, and the lower surface of the mouth flange 15 of the refill container 3 and the container body 2 contact via a high-friction elastic member 5.

[0039] For example, the high friction elastic member 5 may be held by the container body 2 rather than the refill container 3. The seal portion 25 may not be located directly above the contact portion between the high friction elastic member 5 and the container body 2 when the top lid 4 is closed. The stopper portion 19 may not be provided. [Explanation of symbols]
