Description

[Technical Field]

[0001] The present invention relates to a dispensing container. [Background technology]

[0002] A dispensing container generally comprises a cylindrical operating part with a bottom that extends vertically along the container axis, a sleeve that is arranged inside the operating part so as to be rotatable circumferentially around the container axis, and a middle plate that is arranged inside the sleeve so as to be movable up and down while its circumferential rotational movement relative to the sleeve is restricted, and that holds the rod-shaped contents; when the operating part and the sleeve are rotated circumferentially relative to each other, the middle plate moves up and down relative to the operating part and the sleeve. As a dispensing container, for example, as shown in Patent Document 1 below, a configuration is known in which the operating part includes a cylindrical outer body, a cylindrical inner member fitted inside the outer body, and a first magnet, and the lid body includes a cylindrical outer lid, a cylindrical inner lid fitted inside the outer lid, and a second magnet that faces the first magnet in the vertical direction and attracts the first magnet. If the outer peripheral surfaces of the outer body and the outer lid are non-circular when viewed from above and below, it is possible to provide multiple first magnets and multiple second magnets spaced apart in the circumferential direction, and to make the magnetic fields of adjacent first magnets and second magnets opposite to each other in the circumferential direction so that the lid body cannot be attached to the operating unit unless the relative circumferential positions of the outer body and the outer lid are aligned.

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-6700 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional dispensing containers, a first storage tube containing a first magnet is formed in the core, and a second storage tube containing a second magnet is formed in the inner lid. If the relative circumferential positions of the core and outer body, and the inner and outer lids are incorrectly assembled, when the relative circumferential positions of the outer body and outer lid are aligned, the first magnet and second magnet, which repel each other, will face each other in the vertical direction, and it may become impossible to attach the lid to the operating part.

[0005] The present invention provides a dispensing container that can be assembled while adjusting the relative circumferential positions of the core and outer body, and the inner and outer lids, respectively. [Means for solving the problem]

[0006] a sleeve provided inside the operating part so as to be rotatable in a circumferential direction about the container axis; and a central tray provided inside the sleeve so as to be movable up and down while its circumferential rotation relative to the sleeve is restricted, the central tray holding a rod-shaped content; when the operating part and the sleeve are rotated circumferentially relative to each other, the central tray moves up and down relative to the operating part and the sleeve; the operating part comprises a cylindrical outer body, a cylindrical central member fitted inside the outer body, and a first magnet; one of the outer body and the central member is provided with a first housing cylinder extending in a vertical direction and housing the first magnet; and the lid body comprises a cylindrical outer lid, a cylindrical inner lid fitted inside the outer lid, and a second magnet that faces the first magnet in a vertical direction and attracts the first magnet; a second housing tube extending in the vertical direction and housing the second magnet provided in one of the outer lid and the inner lid; a plurality of the first magnets and a plurality of the second magnets are provided at intervals in the circumferential direction, and the magnetic fields of the first magnets and the second magnets adjacent to each other in the circumferential direction have opposite directions; the outer circumferential surfaces of the outer body and the outer lid are non-circular when viewed from the vertical direction; an outer circumferential surface of the outer body is formed with an outer circumferential recess that is recessed radially outward and opens upward; an outer circumferential surface of the core is formed with a core protrusion that protrudes radially outward and is fitted into the outer circumferential recess; an inner circumferential surface of the outer lid is formed with an outer lid recess that is recessed radially outward and opens downward; and an outer circumferential surface of the inner lid is formed with an inner lid protrusion that protrudes radially outward and is fitted into the outer lid recess.

[0007] The inner peripheral surface of the outer casing has an outer casing recess that is recessed radially outward and opens upward, and the outer peripheral surface of the core member has a core member protrusion that protrudes radially outward and is fitted into the outer casing recess.Therefore, the core member cannot be assembled inside the outer casing unless the circumferential positions of the outer casing recess and the core member protrusion are aligned. An outer lid recess portion is formed on the inner surface of the outer lid, which is recessed radially outward and opens downward, and an inner lid protrusion portion is formed on the outer surface of the inner lid, which protrudes radially outward and is fitted into the outer lid recess portion.Therefore, the inner lid cannot be assembled to the inside of the outer lid unless the circumferential positions of the outer lid recess portion and the inner lid protrusion portion are aligned. As a result of the above, it is possible to assemble the core and outer body, as well as the inner and outer lids, by aligning their relative circumferential positions, and it is possible to easily and reliably assemble a dispensing container whose outer peripheral surfaces are non-circular when viewed from above and below, and whose lid cannot be attached to the operating part unless the relative circumferential positions of the outer body and outer lid are aligned.

[0008] The first accommodating tube may include a first support wall that supports one of the two end faces of the first magnet in the vertical direction, and the other of the outer body and the inner fitting may have a first support portion that fixes the first magnet by sandwiching it between the first support wall and the other, and the second accommodating tube may include a second support wall that supports one of the two end faces of the second magnet in the vertical direction, and the other of the outer lid and the inner lid may have a second support portion that fixes the second magnet by sandwiching it between the second support wall and the other.

[0009] The first magnet is fixed by being sandwiched between the first support wall and the first support part in the vertical direction, and the second magnet is fixed by being sandwiched between the second support wall and the second support part in the vertical direction, so that the first magnet can be firmly fixed to the operating part and the second magnet can be firmly fixed to the cover body. [Effects of the Invention]

[0010] According to the present invention, the core and outer body, and the inner and outer lids can be assembled while their relative circumferential positions are aligned. [Brief explanation of the drawings]

[Figure 2B] FIG. 2B is a cross-sectional view taken along the line 2B-2B in FIG. 2A. [Figure 3] FIG. [Figure 4A] FIG. [Figure 4B] FIG. 4B is a cross-sectional view taken along line 4B-4B in FIG. 4A. [Figure 5] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is used by dispensing a stick-shaped content (not shown). Examples of the stick-shaped content include cosmetics (lipstick, lip balm, stick eye shadow, etc.), medicine, glue, etc. The dispensing container 1 comprises a cylindrical operating part 10 with a bottom, a sleeve 11, an inner tray 12, and a lid 13. The operating part 10, the sleeve 11, the inner tray 12, and the lid 13 are arranged with their respective central axes aligned on a common axis.

[0013] Hereinafter, the common axis will be referred to as the container axis O, the side where the lid body 13 is located relative to the operating unit 10 in the direction along the container axis O will be referred to as the upper side, the side where the operating unit 10 is located relative to the lid body 13 in the direction along the container axis O will be referred to as the lower side, and the direction along the container axis O will be referred to as the vertical direction. The direction that intersects with the container axis O when viewed from the vertical direction will be referred to as the radial direction, and the direction that circles around the container axis O when viewed from the vertical direction will be referred to as the circumferential direction. The circumferential direction in which the inner tray 12 is raised relative to the operating part 10 and the sleeve 11 is called the extension direction, and the circumferential direction in which the inner tray 12 is lowered relative to the operating part 10 and the sleeve 11 is called the storage direction.

[0014] The operating unit 10 includes an exterior body 21, a centering member 22, and a first magnet .

[0015] As shown in FIGS. 2A and 2B, the exterior body 21 is formed in a cylindrical shape with a bottom, and is disposed coaxially with the axis O of the container. The outer peripheral surface of the peripheral wall of the exterior body 21 has a non-circular shape when viewed from above and below. In the illustrated example, the outer peripheral surface of the peripheral wall of the exterior body 21 has a non-regular polygonal and rectangular shape when viewed from above and below. A cylindrical fitting portion 21b extending upward is formed on the bottom wall of the exterior body 21. The fitting portion 21b is arranged coaxially with the container axis O. A plurality of slits 21c are formed in the fitting portion 21b at intervals in the circumferential direction, penetrating the fitting portion 21b in the radial direction and opening at the upper end opening edge. Portions of the fitting portion 21b located between adjacent slits 21c in the circumferential direction constitute tongue portions 21d that are elastically deformable in the radial direction. In the illustrated example, four tongue portions 21d are provided, and the circumferential size of one pair of tongue portions 21d facing each other in the radial direction is larger than the circumferential size of another pair of tongue portions 21d facing each other in the radial direction. Of the multiple tongue portions 21d, those tongue portions 21d with smaller circumferential dimensions have engagement portions 21e that protrude radially inward, and those tongue portions 21d with larger circumferential dimensions have first locking projections 21f that protrude radially outward. Engagement portions 21e are provided in the circumferential center of tongue portion 21d and are formed as ridges extending vertically. First locking projections 21f are provided at the upper ends of tongue portion 21d and are formed as ridges extending circumferentially.

[0016] As shown in FIG. 3, the core 22 is formed in a cylindrical shape and is disposed coaxially with the container axis O. The core 22 is formed in a tubular shape with both ends in the vertical direction open. The core 22 is fitted inside the exterior body 21. The core 22 is provided so as not to rotate in the circumferential direction relative to the exterior body 21. A first flange portion 33 is provided at the upper end of the core 22, protruding radially outward and extending around the entire circumference. The first flange portion 33 is disposed on the edge of the upper opening of the peripheral wall of the exterior body 21. When viewed from the vertical direction, the first flange portion 33 has a similar shape to but slightly smaller than the outer circumferential surface of the peripheral wall of the exterior body 21.

[0017] In this embodiment, as shown in Figures 2A and 2B, an outer body recess 36 that is recessed radially outward and opens upward is formed on the inner surface of the peripheral wall of the outer body 21, and an inner body protrusion 37 that protrudes radially outward and is fitted into the outer body recess 36 is formed on the outer surface of the core member 22.

[0018] The exterior body recess 36 protrudes radially outward from the inner circumferential surface of the exterior body 21, which has an arc shape when viewed from above. Two exterior body recesses 36 are provided, one on each side of the container axis O in the radial direction. The inner circumferential surface of the exterior body recess 36 extends linearly along a side portion of the outer circumferential surface of the peripheral wall of the exterior body 21, which has a rectangular shape when viewed from above. The core member protrusion 37 protrudes radially outward from the outer peripheral surface of the core member 22, which has an arc shape when viewed from the top-bottom direction. This prevents the core member protrusion 37 from being inserted into the portion of the inside of the outer casing 21 that has an arc shape when viewed from the top-bottom direction. Two core member protrusions 37 are provided, one on each side of the container axis O in the radial direction. The outer peripheral surface of the core member protrusion 37 extends linearly along the side portions of the outer peripheral surface of the first flange portion 33, which has a rectangular shape when viewed from the top-bottom direction.

[0019] A plurality of first magnets 28 are provided at intervals in the circumferential direction, and the magnetic fields of adjacent first magnets 28 in the circumferential direction have opposite directions. In other words, a first magnet 28 with its north pole located on the upper side and its south pole located on the lower side is adjacent to a first magnet 28 with its south pole located on the upper side and its north pole located on the lower side in the circumferential direction. In the illustrated example, four first magnets 28 are provided at equal intervals in the circumferential direction.

[0020] The first magnet 28 is housed in a first housing tube 34 that extends in the vertical direction and is provided on either the exterior body 21 or the core member 22. In the illustrated example, the first housing tube 34 extends downward from the first flange portion 33 of the core member 22. The first housing tube 34 may also be provided on the exterior body 21. The first housing tube 34 is provided at a position adjacent to a corner of the outer circumferential surface of the first flange portion 33, which has a rectangular shape when viewed from the vertical direction. The first housing tube 34 has a circular shape when viewed from the vertical direction, and is provided so that its inner circumferential surface circumscribes the outer circumferential surface of the core member 22 and its outer circumferential surface is inscribed in the outer circumferential surface of the first flange portion 33. The first housing tube 34 is connected to the circumferential end of the core member extension portion 37.

[0021] The first accommodating cylinder is formed in a topped cylindrical shape. A top wall (first support wall) a of the first accommodating cylinder is formed integrally with the first flange portion 33 and supports the upper end surface of the first magnet . Here, a first recess 35 recessed downward is formed on the edge of the upper opening of the exterior body 21. The first accommodating tube 34 is fitted into the first recess 35. A first support portion 35a is formed on the bottom surface of the inner surface of the first recess 35, which is located at the lower end and faces upward, and which fixes the first magnet 28 by sandwiching it between itself and the top wall 34a of the first accommodating tube 34 in the vertical direction. The first support portion 35a is a protrusion that protrudes upward from the bottom surface of the first recess 35.

[0022] Of the multiple first accommodating tubes 34, the first accommodating tubes 34 that accommodate the first magnets 28 so that the magnetic fields have the same direction have vertical ribs 34b formed on their outer peripheral surfaces, and vertical grooves 35b into which the vertical ribs 34b fit are formed on the inner peripheral surface of the first recesses 35 into which the first accommodating tubes 34 having the vertical ribs 34b fit. The vertical ribs 34b are provided at the radially outer end of the outer peripheral surface of the first accommodating tube 34, and the vertical grooves 35b are provided at the radially outer end of the inner peripheral surface of the first recesses 35.

[0023] A transmission shaft 23 is provided on the upper surface of the bottom wall of the exterior body 21, extending in the vertical direction and supporting the inner tray 12 so that it can move up and down. The transmission shaft 23 includes a fixed shaft member 23a and an outer transmission shaft 23b.

[0024] The fixed shaft member 23 a includes a fitted portion 24 , a seat portion 25 , an inner transmission shaft 26 , and an insertion portion 27 .

[0025] The fitted portion 24 is formed in a cylindrical shape and is disposed coaxially with the container axis O. The fitting portion 21b is inserted into the inside of the fitted portion 24. A second locking protrusion 24a is formed on the inner peripheral surface of the fitted portion 24. The second locking protrusion 24a is locked to a first locking protrusion 21f formed on the tongue portion 21d of the fitting portion 21b from below the first locking protrusion 21f. The second locking protrusion 24a is locked to the first locking protrusion 21f so as to be able to climb over it upward. A circumferential groove 24c is formed on the outer peripheral surface of the upper portion of the fitted portion 24. An annular sliding portion 24d is embedded in the circumferential groove 24c. The sliding portion 24d is made of a material that is softer than the material of the fixed shaft member 23a (e.g., PP), has a lower elastic modulus than the fixed shaft member 23a, and a higher friction coefficient than the fixed shaft member 23a. The sliding portion 24d is formed of a thermoplastic resin such as an elastomer and is fixed to the fixed shaft member 23a by two-color molding together with the fixed shaft member 23a. However, the sliding portion 24d may be formed of, for example, nitrile rubber, butyl rubber, or silicone rubber, and fixed to the fixed shaft member 23a by injection molding the fixed shaft member 23a with the sliding portion 24d as an insert. The sliding portion 24d may be interposed between the sleeve 11 and the exterior body 21.

[0026] The base portion 25 protrudes radially inward from the upper end of the fitted portion 24. The base portion 25 is formed in an annular shape and is disposed coaxially with the container axis O. The upper end opening edge of the fitting portion 21b is in close proximity to or in contact with the lower surface of the inner circumferential portion of the base portion 25 from below.

[0027] The inner transmission shaft 26 extends upward from the inner peripheral edge of the base portion 25. The inner transmission shaft 26 is formed in a cylindrical shape and is disposed coaxially with the container axis O. An inner spiral groove 26a is formed on the outer peripheral surface of the inner transmission shaft 26. The inner spiral groove 26a extends spirally upward in the payout direction. In the illustrated example, two inner spiral grooves 26a are formed. However, the number of inner spiral grooves 26a may be one, or three or more.

[0028] The insertion portion 27 is formed in a cylindrical shape and is disposed coaxially with the container axis O. The insertion portion 27 is inserted into the inside of the fitting portion 21b. On the outer peripheral surface of the insertion portion 27, engaged portions 27a are formed which protrude radially outward and extend in the up-down direction. A plurality of engaged portions 27a are provided at intervals in the circumferential direction. The number of engaged portions 27a is greater than the number of engaging portions 21e formed on the inner peripheral surface of the fitting portion 21b. The engaged portions 27a which are adjacent to each other in the circumferential direction sandwich the engaging portion 21e in the circumferential direction. This makes the fixed shaft member 23a non-rotatable in the circumferential direction relative to the exterior body 21.

[0029] The outer transmission shaft 23b is formed in a cylindrical shape and disposed coaxially with the container axis O. The inner transmission shaft 26 is inserted inside the outer transmission shaft 23b. A first engagement protrusion 31 that protrudes radially inward is formed at the lower end of the outer transmission shaft 23b. The first engagement protrusion 31 is housed (engaged) in the inner spiral groove 26a of the inner transmission shaft 26. As the outer transmission shaft 23b rotates circumferentially relative to the inner transmission shaft 26, the first engagement protrusion 31 moves spirally within the inner spiral groove 26a, causing the outer transmission shaft 23b to move up and down relative to the inner transmission shaft 26. Two first engagement protrusions 31 are provided circumferentially spaced apart to match the number of threads of the inner spiral groove 26a. Each first engagement protrusion 31 extends along the inner spiral groove 26a. An outer spiral groove 32 is formed on the outer peripheral surface of the outer transmission shaft 23b. The outer spiral groove 32 extends spirally upward in the payout direction. In the illustrated example, two outer spiral grooves 32 are formed. However, the outer spiral groove 32 may be one, three or more.

[0030] The sleeve 11 is provided inside the operating unit 10 so as to be rotatable in the circumferential direction relative to the operating unit 10 and the transmission shaft 23. The sleeve 11 is inserted inside the intermediate member 22 and surrounds the outside of the transmission shaft 23. The lower end of the sleeve 11 is inserted between the intermediate member 22 and the base portion 25. The upper opening edge of the sleeve 11 is located above the operating unit 10 and is inclined with respect to the container axis O. The sleeve 11 may be made of a metal material or the like. A protrusion 11a that protrudes radially inward is formed at the lower end of the sleeve 11. When housed in the circumferential groove 24c, the protrusion 11a engages with the upper and lower edges of the circumferential groove 24c and abuts radially against the outer circumferential surface of the sliding contact portion 24d. As a result, the sleeve 11 is rotatable in the circumferential direction relative to the operating unit 10 while its vertical movement relative to the operating unit 10 is restricted, with the protrusion 11a sliding on the outer circumferential surface of the sliding contact portion 24d.

[0031] The inner tray 12 is provided inside the sleeve 11 so as to be movable up and down while its rotational movement in the circumferential direction relative to the sleeve 11 is restricted, and holds stick-shaped contents. The inner tray 12 includes an inner tray body 51 and a hanging tube 52.

[0032] The inner plate body 51 is formed in a cylindrical shape with a bottom and is arranged coaxially with the container axis O. The inner plate body 51 is housed inside the sleeve 11 in a portion located above the transmission shaft 23. A stick-shaped content is held within the inner plate body 51. The stick-shaped content protrudes upward from the inner plate body 51.

[0033] The hanging tube 52 extends downward from the bottom wall of the inner tray body 51. The hanging tube 52 extends downward from the outer peripheral edge of the bottom wall of the inner tray body 51. The hanging tube 52 is disposed between the outer peripheral surface of the transmission shaft 23 and the inner peripheral surface of the sleeve 11. The hanging tube 52 is inserted inside the sleeve 11 and surrounds the outer transmission shaft 23b. A second engagement protrusion 52a that protrudes radially inward is formed at the lower end of the hanging tube 52. The second engagement protrusion 52a is housed (engaged) within the outer spiral groove 32. As the hanging tube 52 rotates in the circumferential direction relative to the outer transmission shaft 23b, the second engagement protrusion 52a moves spirally within the outer spiral groove 32, causing the hanging tube 52 to move up and down relative to the outer transmission shaft 23b. In the example shown in the figure, two second engagement protrusions 52a are provided circumferentially spaced apart to match the number of threads of the outer spiral groove 32. Each second engagement protrusion 52a extends along the outer spiral groove 32. The hanging tube 52 has a plurality of (for example, two) slits 52b formed at intervals in the circumferential direction, the slits 52b penetrating the hanging tube 52 in the radial direction, extending in the up-down direction, and opening on the edge of the lower end opening of the hanging tube 52. This allows portions of the hanging tube 52 located between adjacent slits 52b in the circumferential direction to easily elastically deform in the radial direction. Therefore, when the injection-molded inner plate 12 is released from the mold, elastically deforming the hanging tube 52 in the radial direction makes it easier for the inner circumferential surface of the hanging tube 52 and the core that molds the second engaging protrusions 52a to climb downward over the second engaging protrusions 52a.

[0034] The cover 13 is detachably attached to the operating unit 10 with the upper part of the sleeve 11 inserted inside. The lid body 13 includes an outer lid 41, an inner lid 42, and a second magnet 43.

[0035] The outer lid 41 is formed in a cylindrical shape with a top, and is disposed coaxially with the axis O of the container. The outer peripheral surface of the peripheral wall of outer lid 41 has a non-circular shape when viewed from above. In the illustrated example, the outer peripheral surface of the peripheral wall of outer lid 41 has a non-regular polygonal and rectangular shape when viewed from above. The outer peripheral surfaces of the peripheral walls of outer lid 41 and exterior body 21 are continuous without any steps in the vertical direction.

[0036] The inner lid 42 is formed in a cylindrical shape and is disposed coaxially with the container axis O. The inner lid 42 is formed in a cylindrical shape with a top. The inner lid 42 may also be formed in a cylindrical shape with both ends in the vertical direction open. The inner lid 42 is fitted inside the outer lid 41. The inner lid 42 is provided so as not to be rotatable in the circumferential direction relative to the outer lid 41. A second flange portion 44 is provided at the lower end of the inner lid 42, protruding radially outward and extending around the entire circumference. The second flange portion 44 has a shape similar to but slightly smaller than the outer peripheral surface of the peripheral wall of the outer lid 41 when viewed from the vertical direction.

[0037] In this embodiment, an outer lid recess 45 is formed on the inner surface of the outer lid 41, which is recessed radially outward and opens downward, and an inner lid protrusion 46 is formed on the outer surface of the inner lid 42, which protrudes radially outward and is fitted into the outer lid recess 45. The outer lid recess 45 is formed on the inner peripheral surface of the lower end of the outer lid 41, and the inner lid protrusion 46 is formed on the outer peripheral surface of the lower end of the inner lid .

[0038] Two outer lid recesses 45 are provided, one on each side of the container axis O in the radial direction. The inner peripheral surface of outer lid recess 45 extends linearly along a side portion of the outer peripheral surface of the peripheral wall of outer lid 41, which has a rectangular shape when viewed from above and below. When viewed from the top-bottom direction, the distance between the outer peripheral surface of the inner lid protrusion 46 and the container axis O is greater than the distance between the container axis O and the portion of the inner peripheral surface of the lower end of the outer lid 41 other than the outer lid recess 45. This prevents the inner lid protrusion 46 from being inserted into any portion of the inside of the lower end of the outer lid 41 other than the outer lid recess 45. Two inner lid protrusions 46 are provided, one on each side of the container axis O in the radial direction. When viewed from the top-bottom direction, the outer peripheral surface of the inner lid protrusion 46 has an arc shape extending circumferentially.

[0039] The second magnet 43 faces the first magnet 28 in the vertical direction and attracts the first magnet 28. The magnetic fields of the second magnet 43 and the first magnet 28, which face each other in the vertical direction, are oriented in opposite directions. Similar to the first magnet 28, a plurality of second magnets 43 are provided at intervals in the circumferential direction, and the magnetic fields of the second magnets 43 adjacent to each other in the circumferential direction are oriented in opposite directions.

[0040] The second magnet 43 is housed in a second housing tube 47 that is provided on either the outer lid 41 or the inner lid 42 and extends in the vertical direction. In the example shown, the second housing tube 47 extends upward from the second flange portion 44 of the inner lid 42. The second housing tube 47 may also be provided on the outer lid 41. The second housing tube 47 is provided at a position adjacent to a corner of the outer peripheral surface of the second flange portion 44, which has a rectangular shape when viewed from the vertical direction. The second housing tube 47 has a circular shape when viewed from the vertical direction, and is provided so that its inner peripheral surface is circumscribed by the outer peripheral surface of the inner lid 42 and its outer peripheral surface is inscribed by the outer peripheral surface of the second flange portion 44.

[0041] The second accommodating cylinder 47 is formed in a cylindrical shape with a bottom. A bottom wall (second support wall) 47a of the second accommodating cylinder 47 is formed integrally with the second flange portion 44 and supports the lower end surface of the second magnet 43. Here, a second recess 48 that is recessed upward is formed on the edge of the lower opening of the outer lid 41. The second accommodating tube 47 is fitted into the second recess 48. A second support portion 48a is formed on the inner surface of the second recess 48, on the top surface located at the upper end and facing downward, which fixes the second magnet 43 by sandwiching it between itself and the bottom wall 47a of the second accommodating tube 47 in the vertical direction. The second support portion 48a is a protrusion that protrudes downward from the top surface of the second recess 48.

[0042] Of the multiple second accommodating tubes 47, the second accommodating tubes 47 that accommodate the second magnets 43 so that the magnetic fields have the same direction have vertical ribs 47b formed on their outer peripheral surfaces, and vertical grooves 48b into which the vertical ribs 47b fit are formed on the inner peripheral surfaces of the second recesses 48 into which the second accommodating tubes 47 having the vertical ribs 47b fit. The vertical ribs 47b are provided at the radially outer end of the outer peripheral surface of the second accommodating tube 47, and the vertical grooves 48b are provided at the radially outer end of the inner peripheral surface of the second recesses 48.

[0043] In the dispensing container 1 configured as described above, the second locking protrusion 24a formed on the mating portion 24 of the transmission shaft 23 is engaged with the first locking protrusion 21f formed on the tongue portion 21d of the mating portion 21b of the outer casing 21 so that it can move upward and overcome the first locking protrusion 21f, and therefore the cartridge, which is a combination of the sleeve 11, the inner plate 12, and the transmission shaft 23, is removably assembled to the operating unit 10.

[0044] Next, the operation of the dispensing container 1 described above will be described.

[0045] When using dispensing container 1, first, lid 13 is removed from operating unit 10. Next, operating unit 10 and sleeve 11 are rotated relative to each other in the dispensing direction. At this time, fixed shaft member 23a rotates relative to operating unit 10, and inner plate 12 rotates relative to sleeve 11.

[0046] Furthermore, at this time, depending on the frictional resistance between the various parts of the dispensing container 1, the outer transmission shaft 23b undergoes at least one of the following movements: a first movement in which it rotates relative to the inner transmission shaft 26 of the fixed shaft member 23a relative to the middle tray 12, and a second movement in which it rotates relative to the inner transmission shaft 26. When the first action occurs in the outer transmission shaft 23b, the second engagement protrusion 52a of the inner tray 12 moves spirally within the outer spiral groove 32 of the outer transmission shaft 23b, causing the inner tray 12 to rise relative to the transmission shaft 23b. When the second action occurs on the outer transmission shaft 23b, the first engagement protrusion 31 of the outer transmission shaft 23b moves spirally within the inner spiral groove 26a of the inner transmission shaft 26, causing the outer transmission shaft 23b to rise relative to the inner transmission shaft 26. At this time, the inner surface of the outer spiral groove 32 pushes up the second engagement protrusion 52a of the inner tray 12, causing the inner tray 12 to rise together with the outer transmission shaft 23b. As described above, as the inner tray 12 rises relative to the operating part 10 and the sleeve 11, the stick-shaped contents are dispensed upward from the upper end opening of the sleeve 11.

[0047] When the inner tray 12 is lowered, the operating unit 10 and the sleeve 11 are rotated relative to each other in the storage direction. At this time, just as when the operating unit 10 and the sleeve 11 are rotated relative to each other in the payout direction, the outer transmission shaft 23b undergoes at least one of the following actions: rotating relative to the inner tray 12 together with the inner transmission shaft 26 of the fixed shaft member 23a, and rotating relative to the inner transmission shaft 26. Regardless of the action, the inner tray 12 descends relative to the operating unit 10 and the sleeve 11.

[0048] As described above, in the dispensing container 1 of this embodiment, an outer body recess 36 that is recessed radially outward and opens upward is formed on the inner surface of the peripheral wall of the outer body 21, and an inner body protrusion 37 that protrudes radially outward and is fitted into the outer body recess 36 is formed on the outer surface of the core member 22.Therefore, the core member 22 cannot be assembled inside the outer body 21 unless the circumferential positions of the outer body recess 36 and the core member protrusion 37 are aligned. An outer lid recess 45 is formed on the inner surface of the outer lid 41, which is recessed radially outward and opens downward, and an inner lid protrusion 46 is formed on the outer surface of the inner lid 42, which protrudes radially outward and is fitted into the outer lid recess 45.Therefore, the inner lid 42 cannot be assembled to the inside of the outer lid 41 unless the circumferential positions of the outer lid recess 45 and the inner lid protrusion 46 are aligned.

[0049] As a result, it is possible to assemble the core 22 and outer body 21, and the inner lid 42 and outer lid 41, by aligning their relative circumferential positions, and it is possible to easily and reliably assemble the dispensing container 1, which cannot have the lid body 13 attached to the operating part 10 unless the relative circumferential positions of the outer body 21 and outer lid 41, each of whose outer peripheral surfaces are non-circular when viewed from above and below, are aligned.

[0050] The first magnet 28 is fixed by being sandwiched vertically between the top wall 34a of the first housing tube 34 and the first support portion 35a, and the second magnet 43 is fixed by being sandwiched vertically between the bottom wall 47a of the second housing tube 47 and the second support portion 48a, so that the first magnet 28 can be firmly fixed to the operating portion 10 and the second magnet 43 can be firmly fixed to the lid body 13.

[0051] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0052] In the above-described embodiment, the transmission shaft 23 includes the inner transmission shaft 26 and the outer transmission shaft 23b, but the configuration is not limited to this. The transmission shaft 23 may be configured such that the inner transmission shaft 26, the outer transmission shaft 23b, the base portion 25, and the like are integrally formed. In the above-described embodiment, a configuration has been described in which the fitting portion 21b is formed on the operating unit 10 and the fitted portion 24 is formed on the transmission shaft 23, but the present invention is not limited to this configuration. The fitting portion may be formed on the transmission shaft 23, and the fitted portion may be formed on the operating unit 10. The mechanism for moving inner plate 12 up and down relative to operating unit 10 and sleeve 11 is not limited to a configuration having transmission shaft 23, and may be modified as appropriate. For example, a mechanism similar to that found in other known dispensing containers may be employed, such as a configuration in which an inner plate for holding a rod-shaped content, a sleeve, and an internally threaded cylinder are arranged in this order from the inside to the outside in the radial direction, the inner plate is provided with a protrusion that protrudes outward in the radial direction, the sleeve is formed with a long through hole that extends up and down, and the protrusion engages with the thread groove of the internally threaded cylinder through the long through hole with its circumferential movement restricted by the long through hole.

[0053] The exterior body 21 may be formed in a cylindrical shape with both ends in the vertical direction open, the core member 22 may be formed in a cylindrical shape with a bottom, and the fitting portion 21b may be formed on the bottom wall of the core member 22. The inner lid 42 may be formed in a cylindrical shape with both vertical ends open. The outer lid 41 may be formed in a cylindrical shape with both vertical ends open, and the inner lid 42 may be formed in a cylindrical shape with a top.

[0054] In the above-described embodiment, a configuration in which the cartridge is detachably attached to the operating unit 10 has been described, but the present invention is not limited to this configuration. Dispensing container 1 may be configured such that inner tray 12 and sleeve 11 are not detachable from operating unit 10 (disposable). In this case, inner transmission shaft 26 may be formed integrally with the bottom wall of exterior body 21.

[0055] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments and variations may be combined as appropriate. [Explanation of symbols]
