However, the above-mentioned conventional technology still leaves room for improvement in terms of reducing the number of parts.

The present invention aims to reduce the number of parts and provide a low-cost dispensing container.

In order to solve the above problems, the present invention employs the following aspects.
A first aspect of the present invention is a dispensing container comprising a bottomed, cylindrical operating part; a transmission shaft having a spiral groove extending around a container axis and extending upward from a bottom wall of the operating part; a sleeve arranged inside the operating part surrounding the outside of the transmission shaft and rotatable in a circumferential direction around the container axis relative to the transmission shaft; and a middle plate arranged inside the sleeve and movable up and down relative to the sleeve as the sleeve rotates relative to the transmission shaft, wherein the middle plate comprises a middle plate main body that holds the contents and a tube extending downward from the middle plate main body, and the tube is formed integrally with the middle plate main body.

In this embodiment, by forming the cylinder integrally with the inner plate body, the number of parts can be reduced, providing a low-cost dispensing container.

The second aspect of the present invention is the dispensing container of the first aspect, in which the cylinder includes a movable cylinder having an engagement protrusion that engages with the spiral groove, and a regulating cylinder that engages with the sleeve in the circumferential direction to regulate the rotation of the inner plate relative to the sleeve, and the movable cylinder and the regulating cylinder are integrally formed with the inner plate body.

In this embodiment, by forming the regulating tube integrally with the inner plate body and the movable tube, the number of parts can be reduced compared to the conventional case in which a separate rotation regulating part is provided between the sleeve and the inner plate, and a low-cost dispensing container can be provided.

A third aspect of the present invention is the dispensing container of the second aspect, wherein the sleeve is formed with a vertical groove extending in the up-down direction, and the regulating tube is formed with a rib that is capable of moving up and down within the vertical groove and abuts against the inner surface of the vertical groove in the circumferential direction to regulate the rotation of the inner plate relative to the sleeve.
According to this aspect, the inner plate can be smoothly moved up and down relative to the sleeve.

A fourth aspect of the present invention is a dispensing container of the second or third aspect, wherein the inner plate and the sleeve form a cartridge that is attached and detached integrally to the operating part through an upper end opening of the operating part, and one of the operating part and the transmission shaft is provided with an engaging portion extending in the vertical direction, and the other of the operating part and the transmission shaft is formed with a cylindrical engaged portion into which the engaging portion is inserted in the vertical direction, thereby restricting rotation around the container axis relative to the operating part.
According to this aspect, when attaching the cartridge to the operating unit, the cartridge is inserted into the inside of the operating unit through the upper end opening of the operating unit. As a result, the engaging portion is inserted vertically into the engaged portion, and the engaging portion engages with the engaged portion in a state in which rotation of the dispensing member about the container axis relative to the operating unit is restricted. On the other hand, when removing the cartridge from the operating unit, the cartridge is pulled upward relative to the operating unit. This releases the engagement between the engaging portion and the engaged portion. In other words, with the dispensing container of this aspect, the cartridge can be easily attached and detached from the operating unit by simply inserting and removing the cartridge into and from the operating unit.

A fifth aspect of the present invention is a dispensing container of the second or third aspect, wherein the movable tube is formed in a cylindrical shape arranged coaxially with the container axis, the regulating tube is arranged surrounding the movable tube, and the regulating tube is provided with a deformation suppression portion that is arranged radially closer to the outer peripheral surface of the movable tube than the inner peripheral surface of the regulating tube when the inner plate is attached to the sleeve, and that suppresses deformation of the movable tube radially outward.
For example, when the center plate is in the uppermost position, if the operating part and the sleeve are rotated relative to each other in the extension direction, the movable cylinder may deform radially outward and the engagement protrusion may overcome the upper end of the spiral groove (i.e., the engagement protrusion may overrun).
In contrast, in this aspect, the deformation suppression portion can restrict the radially outward deformation of the movable barrel, thereby preventing the engagement protrusion from climbing over the upper end of the spiral groove, thereby providing a dispensing container with excellent reliability.

A sixth aspect of the present invention is a dispensing container of the fifth aspect, wherein the deformation suppression portion is provided on the regulating tube so as to be displaceable in the radial direction, and the deformation suppression portion has a guide protrusion that is pushed radially inward by the inner surface of the sleeve during the process of the inner plate being attached to the sleeve through the upper end opening of the sleeve.
According to this aspect, since the deformation suppression portion is provided on the regulating tube so as to be displaceable in the radial direction, when the middle plate is attached to the sleeve, the inner surface of the sleeve presses the guide protrusion radially inward as the middle plate descends relative to the sleeve. This allows the deformation suppression portion to approach the movable tube as the middle plate is attached to the sleeve. Therefore, when molding the middle plate, it is possible to suppress a decrease in moldability due to the addition of the deformation suppression portion.

The seventh aspect of the present invention is the dispensing container of the first aspect, in which the cylindrical portion includes a hanging tube disposed between the outer peripheral surface of the transmission shaft and the inner peripheral surface of the sleeve, and the hanging tube has an engagement protrusion that engages with the spiral groove and a regulating portion that circumferentially engages with the sleeve to regulate the rotation of the inner plate relative to the sleeve, and is formed integrally with the inner plate body.

According to this embodiment, by forming the hanging tube integrally with the inner plate body, the number of parts can be reduced compared to the conventional case in which a separate rotation regulating section is provided between the sleeve and the inner plate, thereby making it possible to provide a low-cost dispensing container.
The hanging tube is provided with both an engagement protrusion that engages with the spiral groove and a restriction portion that restricts the rotation of the inner plate relative to the sleeve by engaging with the sleeve in the circumferential direction, forming a single-cylinder structure. This makes it possible to keep the outer diameter of the inner plate thinner than in a double-cylinder structure that includes, for example, a cylinder body provided with an engagement protrusion and a cylinder body provided with a restriction portion, thereby enabling the dispensing container to be slimmer.

The eighth aspect of the present invention is the dispensing container of the seventh aspect, in which, when the inner plate is in the uppermost position, the outer peripheral surface of the hanging tube is in close proximity to or in contact with the inner peripheral surface of the sleeve.

For example, when the center plate is in the uppermost position, if the operating part and the sleeve are rotated relative to each other in the extension direction, the hanging tube may deform radially outward and the engagement protrusion may overcome the upper end of the spiral groove (i.e., the engagement protrusion may overrun).
In contrast, in this aspect, the inner circumferential surface of the sleeve can regulate the radially outward deformation of the hanging tube, thereby preventing the engagement protrusion from climbing over the upper end of the spiral groove, thereby providing a dispensing container with excellent reliability.

A ninth aspect of the present invention is a dispensing container of the seventh or eighth aspect, wherein the sleeve has a vertical groove extending in the up-down direction, and the regulating portion is arranged to be able to move up and down within the vertical groove and abuts against the inner surface of the vertical groove in the circumferential direction, thereby regulating the rotation of the inner plate relative to the sleeve.
According to this aspect, the inner plate can be smoothly moved up and down relative to the sleeve.

The tenth aspect of the present invention is the dispensing container of the seventh or eighth aspect, in which the transmission shaft, the sleeve, and the inner plate form a cartridge that is attached to and detached from the operating part as a unit through an upper end opening of the operating part, and one of the operating part and the transmission shaft is provided with a fitting portion that extends in the vertical direction, and the other of the operating part and the transmission shaft is formed with a cylindrical fitted portion into which the fitting portion is fitted in a state in which rotation of the transmission shaft around the container axis relative to the operating part is restricted by inserting the fitting portion in the vertical direction.

According to this aspect, when attaching the cartridge to the operating unit, the cartridge is inserted into the inside of the operating unit through the upper opening of the operating unit. As a result, the engaging portion is inserted vertically into the engaged portion, and the engaging portion engages with the engaged portion in a state in which rotation of the transmission shaft about the container axis relative to the operating unit is restricted. On the other hand, when removing the cartridge from the operating unit, the cartridge is pulled upward relative to the operating unit. This releases the engagement between the engaging portion and the engaged portion. In other words, with the dispensing container of this aspect, the cartridge can be easily attached and detached from the operating unit simply by inserting and removing the cartridge from the operating unit.

The present invention reduces the number of parts and provides a low-cost dispensing container.

First Embodiment
Hereinafter, a first 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.), medicines, glue, etc.

The dispensing container 1 comprises an operating part (one of the components) 10, a sleeve 11, a middle plate 12, and a cap 13. The operating part 10, the sleeve 11, and the middle plate 12 are arranged with their respective central axes positioned on a common axis. Hereinafter, the common axis is referred to as the container axis O, and the direction along the container axis O is referred to as the up-down direction. In a plan view seen from the up-down direction, the direction intersecting the container axis O is referred to as the radial direction, and the direction going around the container axis O is referred to as the circumferential direction. In this case, within the dispensing container 1, the top wall side of the cap 13 in the up-down direction is referred to as the upper side, and the bottom wall side (bottom wall 21a of the exterior body 21) of the operating part 10 is referred to as the lower side. Additionally, within the circumferential direction, the direction in which the contents are raised is referred to as the dispensing direction, and the direction in which the contents are lowered is referred to as the storage direction.

The operating unit 10 constitutes the exterior part of the lower part of the dispensing container 1. The operating unit 10 is formed as a bottomed cylinder arranged coaxially with the container axis O as a whole. The operating unit 10 comprises an exterior body 21, a centering member 22, and a dispensing member (the other member) 23. The dispensing member 23 is a transmission shaft.

The exterior body 21 is integrally formed in a cylindrical shape with a bottom. A fitting portion 21b that extends upward is formed on the bottom wall 21a of the exterior body 21. The fitting portion 21b is formed in a cylindrical shape that is arranged coaxially with the container axis O.

1 and 2, slits 21c are formed in the fitting portion 21b. The slits 21c extend in the up-down direction and open on the upper end opening edge of the fitting portion 21b. A plurality of slits 21c are formed at intervals in the circumferential direction. In a plan view, if a direction perpendicular to the radial direction (one of the radial directions) is defined as a first direction L1, two slits 21c are provided on each of one side and the other side of the first direction L1 with respect to the container axis O. Among the slits 21c, the interval between adjacent slits 21c1 in the region on one side of the first direction L1, or between adjacent slits 21c2 in the region on the other side, is narrower than the interval between adjacent slits 21c1, 21c2 across the regions on one side and the other side of the first direction L1.

The portion of the fitting portion 21b located between the adjacent slits 21c constitutes a tongue portion 21d. The tongue portion 21d is configured to be elastically deformable in the radial direction. The tongue portion 21d includes a first tongue portion 21d1 located between the slits 21c1 or between the slits 21c2, and a second tongue portion 21d2 located between the slits 21c1 and 21c2. The first tongue portion 21d1 faces each other in the first direction L1. The second tongue portion 21d2 faces each other in the second direction L2, which is perpendicular to the first direction L1 in the radial direction. The circumferential width of the first tongue portion 21d1 is narrower than the circumferential width of the second tongue portion 21d2. However, the interval between each slit 21c (the width of the tongue portion 21d) can be changed as appropriate. The slit 21c is not a required configuration.

The first tongue portion 21d1 is formed with an engagement portion 21e. The engagement portion 21e is a protrusion that protrudes radially inward from the first tongue portion 21d1 and extends in the up-down direction. In the illustrated example, one of the pair of first tongue portions 21d1 facing each other in the first direction L1 is provided with one engagement portion 21e1. The other of the pair of first tongue portions 21d1 facing each other in the first direction L1 is provided with two engagement portions 21e2. The upper edge of each engagement portion 21e is formed in an arc shape that protrudes upward. The engagement portions 21e are formed at equal intervals in the circumferential direction. The number and pitch of the engagement portions 21e can be changed as appropriate.

A first locking projection 21f is formed on the second tongue portion 21d2. The first locking projection 21f protrudes radially outward from the upper end of each second tongue portion 21d2. The first locking projection 21f extends over the entire circumferential length of each second tongue portion 21d2. The first locking projection 21f may be formed on the first tongue portion 21d1.

As shown in FIG. 1, the centering element 22 is formed in a cylindrical shape and arranged coaxially with the exterior body 21. The centering element 22 is fitted into the inside of the exterior body 21 from above. The centering element 22 is provided in a state where it cannot rotate in the circumferential direction relative to the exterior body 21, with its upper end portion protruding upward from the exterior body 21. The centering element 22 may be formed integrally with the exterior body 21. In addition, in the operating unit 10, the planar shape of the peripheral wall 21g of the exterior body 21 may be a shape other than a circle, as long as the inner circumferential surface of the centering element 22 is formed in a circular shape in a planar view.

The feeding member 23 extends upward from the bottom wall of the operation unit 10. The feeding member 23 supports the inner tray 12 inside the exterior body 21 so that the inner tray 12 can move up and down. The feeding member 23 includes a fixed shaft member 23a and an outer transmission shaft 23b.
The fixed shaft member 23a is provided so as to be non-rotatable in the circumferential direction relative to the exterior body 21. Specifically, the fixed shaft member 23a includes a fitted portion 24, a seat portion 25, an inner transmission shaft 26, and an insertion portion 27.

The fitted portion 24 is formed in a cylindrical shape arranged coaxially with the container axis O. The fitting portion 21b is fitted into the inside of the fitted portion 24 via an undercut. Specifically, the fitted portion 24 is formed with a second locking projection 24a. The second locking projection 24a protrudes radially inward from the middle part of the fitted portion 24 in the up-down direction. The second locking projection 24a extends over the entire circumferential length of the fitted portion 24. The second locking projection 24a is locked to the first locking projection 21f from below the first locking projection 21f.

The lower end of the mated portion 24 is formed with a protruding portion 24b that protrudes outward in the radial direction. A circumferential groove 24c is formed on the upper portion of the mated portion 24. The circumferential groove 24c opens on the outer circumferential surface of the mated portion 24 and extends around the entire circumferential surface of the mated portion 24. A sliding portion 24d is embedded in the circumferential groove 24c. The sliding portion 24d extends around the entire circumferential surface of the mated portion 24d. The sliding portion 24d is made of a material that is softer than the material of the fixed shaft member 23a (e.g., PP, etc.), has a higher elastic modulus than the fixed shaft member 23a, and has a higher friction coefficient than the fixed shaft member 23a. The sliding portion 24d is fixed to the fixed shaft member 23a by two-color molding of a thermoplastic resin such as an elastomer together with the fixed shaft member 23a. However, the sliding contact portion 24d may be fixed to the fixed shaft member 23a by insert molding the fixed shaft member 23a with nitrile rubber, butyl rubber, silicone rubber, or the like as an insert. The sliding contact portion 24d may be interposed between the sleeve 11 and the exterior body 21.

The base portion 25 protrudes radially inward from the upper opening edge of the mating portion 24. The base portion 25 is formed in a circular ring shape that is arranged coaxially with the container axis O. The upper edge of the mating portion 21b is close to or abuts against the inner peripheral portion of the base portion 25 from below.

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 arranged coaxially with the container axis O. An inner spiral groove (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 this embodiment, the inner spiral groove 26a is formed in two strips. However, the inner spiral groove 26a may be one strip or three or more strips.

1 and 3, the insertion portion 27 is formed in a cylindrical shape arranged coaxially with the container axis O. When the fitting portion 21b is fitted into the fitting portion 24, the insertion portion 27 is inserted into the fitting portion 21b. The insertion portion 27 is formed with an engaged portion 27a. The engaged portion 27a protrudes radially outward from the insertion portion 27 and extends in the vertical direction. The lower edge of the engaged portion 27a is formed in an arc shape that protrudes downward. A plurality of engaged portions 27a are formed at intervals in the circumferential direction in the insertion portion 27, and in this embodiment are provided in a knurled shape. The number of engaged portions 27a is greater than the number of engaging portions 21e. When the fitting portion 21b is fitted into the fitting portion 24, the engaging portion 21e1 is sandwiched in the circumferential direction by the engaged portions 27a located on both sides of the engaging portion 21e in the circumferential direction. On the other hand, the engaging portion 21e2 is sandwiched in the circumferential direction between the engaged portion 27a located between the two engaging portions 21e2 and the engaged portion 27a located on the circumferential outside of the two engaging portions 21e2. As a result, the engaging portion 21e and the engaged portion 27a are engaged in the circumferential direction, thereby restricting the relative rotation of the fixed shaft member 23a with respect to the operating unit 10.

The outer transmission shaft 23b surrounds the inner transmission shaft 26 on the outside of the inner transmission shaft 26. 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 accommodated (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. In this embodiment, 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 at an angle 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 this embodiment, the outer spiral groove 32 is formed in two rows. However, the outer spiral groove 32 may be formed in one row or in three or more rows.

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. The sleeve 11 is formed in a cylindrical shape arranged coaxially with the container axis O. The sleeve 11 is inserted into the operating unit 10 through the gap between the center piece 22 and the base portion 25 inside the center piece 22. Therefore, the sleeve 11 surrounds the periphery of the payout member 23. The lower edge of the sleeve 11 is supported from below by the protruding portion 24b. The upper edge of the sleeve 11 is inclined with respect to the container axis O above the operating unit 10. The sleeve 11 may be formed from a metal material or the like.

As shown in FIGS. 1 and 4, the sleeve 11 is formed with a protrusion 11a.
The protrusion 11a protrudes radially inward from the lower end of the sleeve 11. The protrusion 11a engages with the upper and lower opening edges of the circumferential groove 24c while being housed in the circumferential groove 24c. As a result, the sleeve 11 is supported by the fixed shaft member 23a so as to be rotatable in the circumferential direction while its movement in the up and down directions relative to the operating unit 10 is restricted.

A thin wall portion 11b is formed in a portion of the sleeve 11 that is located above the protrusion 11a. The thin wall portion 11b extends around the entire circumference of the lower end of the sleeve 11 in the circumferential direction.
A vertical groove 11c is formed in a portion of the sleeve 11 located above the thin-walled portion 11b. The vertical groove 11c opens on the inner peripheral surface of the sleeve 11. The vertical groove 11c extends in the up-down direction. The lower end of the vertical groove 11c terminates at the thin-walled portion 11b at the lower end of the sleeve 11. The upper end of the vertical groove 11c terminates at the center of the sleeve 11 in the up-down direction. A plurality of vertical grooves 11c (e.g., eight vertical grooves) are formed at intervals in the circumferential direction. The vertical grooves 11c may also penetrate the sleeve 11 in the radial direction.

The middle plate 12 is provided in the sleeve 11 so as to be movable up and down relative to the sleeve 11 while its circumferential rotation relative to the sleeve 11 is restricted. The middle plate 12 includes a middle plate body 51, a movable cylinder (movable shaft) 52, and a restricting cylinder 53. In this embodiment, the middle plate body 51, the movable cylinder 52, and the restricting cylinder 53 are integrally formed. The middle plate 12 includes the middle plate body 51 that holds the contents, and a cylinder extending downward from the middle plate body 51, and the cylinder includes the movable cylinder 52 and the restricting cylinder 53. This will be described in detail below.
The inner plate body 51 is formed in a bottomed cylindrical shape coaxial with the container axis O. The inner plate body 51 is accommodated inside the sleeve 11 in a portion located above the inner transmission shaft 26. The inner plate body 51 is filled with contents. The contents are filled in a state where they protrude upward from the inner plate body 51.

The movable cylinder 52 is integrally formed with the inner plate body 51. The movable cylinder 52 extends downward from the bottom wall of the inner plate body 51. The movable cylinder 52 is inserted inside the sleeve 11 and surrounds the outer transmission shaft 23b. A second engagement protrusion (engagement protrusion) 52a that protrudes radially inward is formed at the lower end of the movable cylinder 52. The second engagement protrusion 52a is accommodated (engaged) in the outer spiral groove 32. As the movable cylinder 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, so that the movable cylinder 52 moves up and down relative to the outer transmission shaft 23b. In this embodiment, two second engagement protrusions 52a are provided at intervals in the circumferential direction in accordance with the number of threads of the outer spiral groove 32. Each second engagement protrusion 52a extends at an angle along the outer spiral groove 32.

A slit 52b is formed in the movable cylinder 52. The slit 52b penetrates the movable cylinder 52 in the radial direction and extends in the vertical direction. The slit 52b opens on the lower edge of the movable cylinder 52. A plurality of slits 52b (for example, two) are formed at intervals in the circumferential direction. As a result, the movable cylinder 52 is divided into two in the circumferential direction by the slits 52b, and is formed to be easily elastically deformed in the radial direction.

As shown in Figures 1 and 5, the regulating tube 53 extends downward from a portion of the bottom wall of the inner plate body 51 that is located outside the movable tube 52. The regulating tube 53 is arranged coaxially with the container axis O. In the illustrated example, the outer diameter of the regulating tube 53 is larger than the outer diameter of the inner plate body 51. The lower edge of the regulating tube 53 is located at the same height as the lower edge of the movable tube 52.

A rib 53a is formed on the outer peripheral surface of the regulating tube 53. The rib 53a protrudes radially outward from the regulating tube 53 and extends in the vertical direction. The vertical length of the rib 53a is shorter than the length of the vertical groove 11c. In the illustrated example, the lower edge of the rib 53a reaches the lower edge of the regulating tube 53. The upper edge of the rib 53a reaches the middle part of the regulating tube 53. Multiple ribs 53a (for example, four) are formed at intervals in the circumferential direction. In other words, the number of ribs 53a is fewer than the vertical grooves 11c. However, the number of ribs 53a and vertical grooves 11c can be changed as appropriate.

Each rib 53a is accommodated (engaged) in a corresponding vertical groove 11c. The ribs 53a move up and down within the vertical groove 11c in accordance with the up and down movement of the middle plate 12 relative to the sleeve 11. The ribs 53a abut against the inner surface (surface facing the circumferential direction) of the vertical groove 11c, thereby restricting the rotation of the middle plate 12 relative to the sleeve 11. In other words, the middle plate 12 is configured to be able to move up and down relative to the sleeve 11 while its rotation relative to the sleeve 11 is restricted by the ribs 53a.

The cap 13 is formed in a cylindrical shape with a top and is arranged coaxially with the container axis O. The inner plate 12 is removably attached to the cap 13 with the upper part of the sleeve 11 inserted through it.

Next, there will be described the operation of the above-mentioned dispensing container 1. In the following explanation, first, a method of using the dispensing container 1 will be described.
When using the dispensing container 1, first, the cap 13 is removed from the operating part 10. Next, the sleeve 11 and the exterior body 21 (peripheral wall 21g) are grasped, and the operating part 10 and the sleeve 11 are rotated relative to each other in the dispensing direction. At this time, since the center fixture 22 and the fixed shaft member 23a are attached to the exterior body 21 so as not to rotate relative to each other, the exterior body 21, the center fixture 22 and the fixed shaft member 23a rotate together. Meanwhile, since the sleeve 11 and the middle plate 12 are attached so as not to rotate relative to each other, the sleeve 11 and the middle plate 12 rotate together.

When the operating part 10 and the sleeve 11 are rotated relative to each other, at least one of the following occurs: the inner transmission shaft 26 and the outer transmission shaft 23b rotate together relative to the movable cylinder 52, or the inner transmission shaft 26 rotates relative to the outer transmission shaft 23b.

When the inner transmission shaft 26 and the outer transmission shaft 23b rotate together relative to the movable cylinder 52, the second engagement protrusion 52a moves spirally within the outer spiral groove 32 while engaged within the outer spiral groove 32, causing the movable cylinder 52 (middle plate 12) to rise relative to the payout member 23. This operation in which the payout member 23 and the movable cylinder 52 rotate relative to each other in the payout direction to cause the middle plate 12 to rise is referred to in this specification as the "first operation."

When the inner transmission shaft 26 rotates relative to the outer transmission shaft 23b, the first engagement protrusion 31, engaged within the inner spiral groove 26a, moves spirally within the inner spiral groove 26a, causing the outer transmission shaft 23b to rise relative to the inner transmission shaft 26. At this time, the second engagement protrusion 52a is pushed up via the inner surface of the outer spiral groove 32, causing the middle plate 12 to rise together with the outer transmission shaft 23b. This operation in which the inner transmission shaft 26 and the outer transmission shaft 23b rotate relative to each other in the payout direction, causing the middle plate 12 to rise together with the outer transmission shaft 23b, is referred to as the "second operation" in this specification.

In other words, as shown in Figures 1 and 6, when the operating part 10 and the sleeve 11 are rotated relative to each other in the dispensing direction, the inner tray 12 rises due to at least one of the first and second actions. This causes the contents to be dispensed upward from the sleeve 11. Whether the first or second action occurs varies depending on factors such as frictional resistance between the various components. However, regardless of which action takes precedence, the contents are dispensed and the user can use them. It should be noted that both the first and second actions may occur simultaneously.

When the middle plate 12 rises relative to the sleeve 11, the rib 53a is guided within the vertical groove 11c. This restricts the rotation of the middle plate 12 relative to the sleeve 11, and the middle plate 12 rises relative to the sleeve 11. The rib 53a comes into contact with the upper edge of the vertical groove 11c, restricting the rise of the middle plate 12 relative to the sleeve 11. This allows the middle plate 12 to reach its uppermost position.

When lowering the middle plate 12, the operating part 10 and the sleeve 11 are rotated relative to each other in the storage direction. Then, the inner transmission shaft 26 and the outer transmission shaft 23b rotate integrally relative to the movable cylinder 52, or the inner transmission shaft 26 rotates relative to the outer transmission shaft 23b, causing the middle plate 12 to lower relative to the sleeve 11. That is, when the middle plate 12 lowers relative to the sleeve 11, the rib 53a is guided into the vertical groove 11c. The middle plate 12 lowers relative to the sleeve 11 after its rotation relative to the sleeve 11 is restricted. The rib 53a comes into contact with the vicinity of the thin-walled portion 11b, thereby restricting the lowering of the middle plate 12 relative to the sleeve 11. This causes the middle plate 12 to reach the lowest position.

1 and 6 , in the dispensing container 1 described above, a cartridge 101, which is a combination of a sleeve 11, a middle plate 12, and a dispensing member 23, is detachably attached to an exterior module 100, which is a combination of an exterior body 21 and a middle member 22. A method for attaching and detaching (replacing) the cartridge 101 to and from the exterior module 100 will be described below.
First, to assemble the cartridge 101 to the exterior module 100, the cartridge 101 is inserted into the exterior module 100 through the upper end opening of the exterior module 100 (core 22). Then, the second locking projection 24a of the fitted portion 24 comes into contact with the first locking projection 21f of the fitting portion 21b from above, and in this state, the cartridge 101 is pushed downward into the exterior module 100 so that the engaging portion 21e and the engaged portion 27a do not overlap in a plan view. In this embodiment, since the engaged portion 27a is formed in a knurled shape, the cartridge 101 can be pushed downward into the exterior module 100 without alignment.

Then, the second locking protrusion 24a climbs over the first locking protrusion 21f downward, and the second locking protrusion 24a is locked to the first locking protrusion 21f from below. This causes the engaging portion 21b to be undercut-fitted into the engaging portion 24. Thereafter, the engaging portion 24 approaches or abuts the bottom wall 21a, completing the insertion of the cartridge 101. In this state, the vertical movement of the cartridge 101 relative to the exterior module 100 is restricted.

Meanwhile, in the process in which the second locking projection 24a passes over the first locking projection 21f downward, the engaging portion 21e enters between the adjacent engaged portions 27a. This causes the engaging portion 21e and the engaged portion 27a to engage in the circumferential direction. As a result, the circumferential movement of the fixed shaft member 23a relative to the exterior body 21 is restricted. In addition, as the engaging portion 21e enters between the adjacent engaged portions 27a, the insertion portion 27 is inserted inside the fitting portion 21b. This causes the fitting portion 21b to be radially sandwiched between the inserting portion 27 and the fitted portion 24. As a result, the radial movement of the cartridge 101 relative to the exterior module 100 is restricted.
With the above, the mounting of the cartridge 101 into the exterior module 100 is completed.

When the cartridge 101 is to be removed from the exterior module 100 after the contents have been used up, the cartridge 101 is pulled upward relative to the exterior module 100. Then, the second locking projection 24a moves upward over the first locking projection 21f, and the engagement between the fitted portion 24 and the engaging portion 21b is released. Furthermore, by pulling the cartridge 101 up relative to the exterior module 100, the engaging portion 21b comes out from between the fitted portion 24 and the insertion portion 27, and the engaging portion 21e comes out from between the adjacent engaged portions 27a.
As a result, the cartridge 101 is removed from the exterior module 100 .

Here, in the dispensing container 1 of this embodiment, the middle plate 12 comprises a middle plate main body 51 that holds the contents, a movable tube 52 extending downward from the middle plate main body 51, and a regulating tube 53 that extends downward from the middle plate main body 51 and engages circumferentially with the sleeve 11, thereby regulating the rotation of the middle plate relative to the sleeve 11, and the middle plate main body 51, the movable tube 52 and the regulating tube 53 are formed as a single unit.
According to this configuration, by forming the regulating tube 53 integrally with the inner plate body 51 and the movable tube 52, the number of parts can be reduced compared to the conventional case in which a separate rotation regulating part is provided between the sleeve and the inner plate, thereby making it possible to provide a low-cost dispensing container 1.

In the dispensing container 1 of this embodiment, a vertical groove 11c extending in the vertical direction is formed in the sleeve 11, and the regulating tube 53 is configured to be able to move up and down within the vertical groove 11c, and to have a rib 53a formed therein that abuts against the inner surface of the vertical groove 11c in the circumferential direction, thereby regulating the rotation of the inner plate 12 relative to the sleeve 11.
According to this configuration, the inner plate 12 can be smoothly moved up and down relative to the sleeve 11.

In the dispensing container 1 of this embodiment, the operating portion 10 has an engaging portion 21b extending upward from the bottom wall 21a, and the dispensing member 23 has a fitted portion 24 that is fitted into the engaging portion 21b in the vertical direction.
According to this configuration, when attaching the cartridge 101 to the exterior module 100, the cartridge 101 is inserted into the inside of the exterior module 100 through the upper end opening of the exterior module 100. As a result, the fitting portion 21b is inserted vertically into the fitted portion 24, and the fitting portion 21b fits into the fitted portion 24. On the other hand, when removing the cartridge 101 from the exterior module 100, the cartridge 101 is pulled upward relative to the exterior module 100. As a result, the fitting portion 21b is disengaged from the fitted portion 24. That is, in the dispensing container 1 of this embodiment, the cartridge 101 can be easily attached to and detached from the exterior module 100 simply by inserting and removing the cartridge 101 from the exterior module 100.

Second Embodiment
The second embodiment differs from the first embodiment described above in that a deformation suppression portion 200 is provided on the regulating tube 53 .
In the dispensing container 1 shown in Figs. 8 and 9, the regulating tube 53 is formed with a through hole 53b. The through hole 53b penetrates the lower part of the regulating tube 53 in the radial direction at a position offset in the circumferential direction with respect to the rib 53a. The through hole 53b is formed so that at least a part of the through hole 53b overlaps with the part of the movable tube 52 located between the slits 52b (hereinafter referred to as the middle foot portion 210) when viewed from the radial direction. That is, the through hole 53b is disposed so that at least a part of the through hole 53b is offset in the circumferential direction with respect to the slit 52b. A plurality of through holes 53b (two in this embodiment) are formed with intervals in the circumferential direction. In the illustrated example, each through hole 53b overlaps with the second engagement protrusion 52a formed on each middle foot portion 210 when viewed from the radial direction. Note that, if the movable tube 52 is elastically deformable in the radial direction, the slit 52b is not an essential component.

A deformation suppressing portion 200 is provided in each through hole 53b. Each deformation suppressing portion 200 is configured to be elastically displaceable in the radial direction through the through hole 53b. That is, each deformation suppressing portion 200 is disposed so as to overlap with the second engagement protrusion 52a when viewed from the radial direction. The deformation suppressing portion 200 includes a base piece 201 and a guide protrusion 202.
The base piece 201 extends downward in a cantilever manner from the upper edge of the through hole 53b. The upper edge of the base piece 201 is connected to the upper edge of the through hole 53b via a thin hinge portion 203. This allows the deformation suppression portion 200 to be connected to the regulating tube 53 rotatably around the hinge portion 203. The hinge portion 203 may be provided on the lower edge or side edge of the through hole 53b. The deformation suppression portion 200 is not limited to being elastically displaceable, and may be configured to be at least displaceable.

The guide protrusion 202 protrudes radially outward from the lower portion of the base piece 201. The guide protrusion 202 is formed in a triangular or trapezoidal shape when viewed from the circumferential direction. Specifically, the guide protrusion 202 has an inclined surface whose radially outward protrusion amount gradually increases from the lower edge of the base piece 201 toward the top.

As shown in FIG. 11, when the middle plate 12 is attached within the sleeve 11, at least a portion of the deformation suppression portion 200 is located radially inward from the inner circumferential surface of the regulating tube 53. Specifically, the deformation suppression portion 200 is inclined radially inward as it extends downward. Therefore, the lower edge of the base piece 201 is close to or abuts against the outer circumferential surface of the movable tube 52 (middle foot portion 210) from the radial outside. The deformation suppression portion 200 restricts the radially outward deformation of the movable tube 52 by the outer circumferential surface of the middle foot portion 210 abutting against it from the radial inside.

10, before the middle plate 12 is inserted into the sleeve 11, the base piece 201 is located in the through hole 53b, and the guide protrusion 202 protrudes radially outward from the outer circumferential surface of the regulating tube 53. That is, in the illustrated example, the deformation suppression part 200 does not protrude radially inward from the inner circumferential surface of the regulating tube 53. In this state, when the middle plate 12 is inserted into the sleeve 11, the inclined surface of the guide protrusion 202 abuts against the upper end opening edge of the sleeve 11. When the middle plate 12 is then further pushed into the sleeve 11, the inclined surface of the guide protrusion 202 slides on the upper end opening edge of the sleeve 11. As a result, as shown in FIG. 11, as the middle plate 12 moves downward relative to the sleeve 11, the guide protrusion 202 is pushed radially inward, and the deformation suppression part 200 is displaced radially inward. As a result, the deformation suppression part 200 approaches the outer circumferential surface of the movable tube 52.

Then, as the middle plate 12 moves downward, the guide protrusion 202 slides on the inner peripheral surface of the sleeve 11, restricting the deformation suppression part 200 from returning radially outward. As a result, the middle plate 12 can be attached to the sleeve 11 with the deformation suppression part 200 in close proximity to the outer peripheral surface of the movable cylinder 52.

In the dispensing container 1 of this embodiment, the slits 52b are formed in the movable cylinder 52, so that when the inner plate 12 (movable cylinder 52) is released from the mold, the middle foot portion 210 is elastically deformed, making it easier for the second engagement protrusions 52a to climb over the molding die. This makes it possible to improve manufacturing efficiency and yield.
On the other hand, when the dispensing container 1 is in use, for example when the center plate 12 is at the uppermost position, if the operating part 10 and the sleeve 11 are rotated relative to each other in the dispensing direction at a point when the second engagement protrusion 52a has reached the upper end of the outer spiral groove 32, the second engagement protrusion 52a may climb over the upper end of the outer spiral groove 32 while the middle foot part 210 elastically deforms radially outward (i.e., overrun of the second engagement protrusion 52a may occur). In contrast, in this embodiment, as shown in Fig. 12, the deformation suppressing part 200 can restrict the radially outward deformation of the middle foot part 210. Therefore, it is possible to suppress the second engagement protrusion 52a from climbing over the upper end of the outer spiral groove 32. As a result, a dispensing container 1 with excellent reliability can be provided.

Moreover, in this embodiment, since the deformation suppression portion 200 is provided on the regulating tube 53 so as to be radially displaceable, when the middle plate 12 is attached to the sleeve 11, the inner surface of the sleeve 11 pushes the guide protrusion 202 radially inward as the middle plate 12 descends relative to the sleeve 11. This allows the deformation suppression portion 200 to be brought closer to the movable tube 52 as the middle plate 12 is attached to the sleeve 11. Therefore, when molding the middle plate 12, it is possible to suppress a decrease in moldability due to the addition of the deformation suppression portion 200.

In the second embodiment, the configuration in which the deformation suppression portion 200 is provided for each through hole 53b has been described, but the present invention is not limited to this configuration. A plurality of deformation suppression portions 200 may be provided for each through hole 53b. In addition, the deformation suppression portion 200 may be provided on the lower end edge of the regulating tube 53, for example, in a configuration in which no through hole 53b is provided.
In the second embodiment, the deformation suppression portion 200 is configured to be displaceable in the radial direction. However, the present invention is not limited to this configuration. The deformation suppression portion 200 may be located in advance radially inside the inner circumferential surface of the regulating tube 53.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the scope of the attached claims.
In the above embodiment, the configuration in which the payout member 23 includes the inner transmission shaft 26 and the outer transmission shaft 23b has been described, but the payout member 23 is not limited to this configuration. It is sufficient that the payout member 23 has at least the inner transmission shaft 26.
In the above-described embodiment, a configuration including the exterior body 21 and the center tool 22 as the operating part has been described, but the present invention is not limited to this configuration. The operating tube part may include only the exterior body 21. In the above-described embodiment, a configuration has been described in which a spiral groove is formed on the outer circumferential surface of the inner transmission shaft 26, and the movable tube (movable shaft) 52 surrounds the outside of the inner transmission shaft 26, but the present invention is not limited to this configuration. For example, a configuration may be used in which a spiral groove is formed on the inner circumferential surface of the cylindrical inner transmission shaft 26, and the movable tube (movable shaft) 52 having an engagement protrusion is disposed inside the inner transmission shaft 26.

In the above-described embodiment, the fitting portion, the fitted portion, and the insertion portion according to the present invention are formed in a cylindrical shape, but the present invention is not limited to this configuration. As long as at least the fitted portion is cylindrical, the fitting portion may be columnar or the like.
In the above embodiment, the configuration in which the fitting portion 21b is formed on the operating portion (one member) 10 and the fitted portion 24 is formed on the advancing member (the other member) 23 has been described, but the present invention is not limited to this configuration. The fitting portion may be formed on the advancing member (one member) 23 and the fitted portion may be formed on the operating portion (the other member) 10.

In the above embodiment, a configuration in which the sleeve 11 is formed with the vertical groove 11c and the rib 53a is formed on the regulating tube 53 has been described, but the present invention is not limited to this configuration. The regulating tube 53 may be configured to regulate the rotation of the inner plate 12 relative to the sleeve 11. In this case, the regulating tube 53 may be formed with the vertical groove and the sleeve 11 may be formed with the rib.
In the above embodiment, a configuration in which cartridge 101 is detachably attached to exterior module 100 has been described, but the present invention is not limited to this configuration. Dispensing container 1 may be configured such that inner plate 12 and sleeve 11 cannot be detached from operation unit 10 (are disposable). In this case, inner transmission shaft 26 may be formed integrally with bottom wall 21a of exterior body 21.

In the above embodiment, the configuration according to the present invention has been described in which the mating portion and the non-mating portion are formed to have a circular (cylindrical) shape in plan view, but this is not limited to this configuration. The mating portion and the mated portion may have corresponding polygonal shapes in plan view. In this case, when the mating portion and the mated portion are mated with each other, the corresponding corners engage with each other in the circumferential direction, thereby restricting relative rotation in the circumferential direction between the mating portion and the mated portion. In other words, the corresponding corners form a rotation prevention portion.

Third Embodiment
A third embodiment of the present invention will now be described with reference to the drawings.
The dispensing container 1A shown in Fig. 13 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.), medicines, glue, etc.

The dispensing container 1A comprises an operating part (one member) 10A, a transmission shaft (the other member) 23A, a sleeve 11A, a middle plate 12A, and a cap 13A. The operating part 10A, the transmission shaft 23A, the sleeve 11A, and the middle plate 12A are arranged with their respective central axes positioned on a common axis. Hereinafter, the common axis is referred to as the container axis O, and the direction along the container axis O is referred to as the up-down direction. In a plan view seen from the up-down direction, the direction intersecting the container axis O is referred to as the radial direction, and the direction going around the container axis O is referred to as the circumferential direction. In this case, the top wall side of the cap 13A in the up-down direction of the dispensing container 1A is referred to as the upper side, and the bottom wall side (bottom wall 21aA of the exterior body 21A) of the operating part 10A is referred to as the lower side. In addition, within the circumferential direction, the direction in which the middle plate 12A is raised is referred to as the dispensing direction, and the direction in which the middle plate 12A is lowered is referred to as the storage direction.

The operating unit 10A constitutes the exterior part of the lower part of the dispensing container 1A. The operating unit 10A is formed as a bottomed cylinder that is aligned coaxially with the container axis O as a whole. The operating unit 10A includes an exterior body 21A and a centering element 22A.

The exterior body 21A is integrally formed in a cylindrical shape with a bottom. A fitting portion 21bA that extends upward is formed on the bottom wall 21aA of the exterior body 21A. The fitting portion 21bA is formed in a cylindrical shape that is arranged coaxially with the container axis O.

As shown in Figures 13 and 14, a slit 21cA is formed in the fitting portion 21bA. The slit 21cA extends in the up-down direction and opens on the upper end opening edge of the fitting portion 21bA. A plurality of slits 21cA are formed at intervals in the circumferential direction. In a plan view, if one of the radial directions is the first direction L1, two slits 21cA are provided on each side of the first direction L1 with respect to the container axis O. Among the slits 21cA, the intervals between adjacent slits 21c1A in the region on one side of the first direction L1 and between adjacent slits 21c2A in the region on the other side are narrower than the intervals between adjacent slits 21c1A and 21c2A across the regions on one side and the other side of the first direction L1.

The portion of the fitting portion 21bA located between the circumferentially adjacent slits 21cA constitutes a tongue portion 21dA. The tongue portion 21dA is configured to be elastically deformable in the radial direction. The tongue portion 21dA includes a first tongue portion 21d1A located between the slits 21c1A and between the slits 21c2A, and a second tongue portion 21d2A located between the slits 21c1A and 21c2A. The first tongue portions 21d1A face each other in the first direction L1. The second tongue portions 21d2A face each other in the second direction L2, which is perpendicular to the first direction L1 in the radial direction. The circumferential width of the first tongue portion 21d1A is narrower than the circumferential width of the second tongue portion 21d2A. However, the interval between each slit 21cA (the width of the tongue portion 21dA) can be changed as appropriate. Note that slit 21cA is not a required component.

The first tongue portion 21d1A is formed with an engagement portion 21eA. The engagement portion 21eA is a protrusion that protrudes radially inward from the first tongue portion 21d1A and extends in the vertical direction. In the illustrated example, one of the pair of first tongue portions 21d1A facing each other in the first direction L1 is provided with one engagement portion 21e1A. The other of the pair of first tongue portions 21d1A facing each other in the first direction L1 is provided with two engagement portions 21e2A. The upper edge of each engagement portion 21eA is formed in an arc shape that protrudes upward. The number and pitch of the engagement portions 21eA can be changed as appropriate.

A first locking projection 21fA is formed on the second tongue portion 21d2A. The first locking projection 21fA protrudes radially outward from the upper end of each second tongue portion 21d2A. The first locking projection 21fA extends over the entire circumferential length of each second tongue portion 21d2A. The first locking projection 21fA may be formed on the first tongue portion 21d1A.

As shown in FIG. 13, the centering element 22A is formed in a cylindrical shape and is arranged coaxially with the outer body 21A. The centering element 22A is fitted from above into the inside of the outer body 21A. The centering element 22A is provided in a state where it cannot rotate in the circumferential direction relative to the outer body 21A, with its upper portion protruding upward from the outer body 21A. The centering element 22A may be formed integrally with the outer body 21A. Furthermore, as long as the inner peripheral surface of the centering element 22A is formed in a circular shape in a plan view, the plan view shape of the peripheral wall 21gA of the outer body 21A may be a shape other than a circle.

The transmission shaft 23A extends upward from the bottom wall of the operation unit 10A. The transmission shaft 23A supports the inner tray 12A inside the exterior body 21A so that the inner tray 12A can move up and down. The transmission shaft 23A includes a fixed shaft member 23aA and an outer transmission shaft 23bA.
The fixed shaft member 23aA is provided so as to be unable to rotate in the circumferential direction relative to the exterior body 21A. Specifically, the fixed shaft member 23aA includes a fitted portion 24A, a seat portion 25A, an inner transmission shaft 26A, and an insertion portion 27A.

The fitted portion 24A is formed in a cylindrical shape arranged coaxially with the container axis O. The fitting portion 21bA is undercut fitted to the inside of the fitted portion 24A. Specifically, the fitted portion 24A is formed with a second locking projection 24aA. The second locking projection 24aA protrudes radially inward from the middle part of the fitted portion 24A in the vertical direction. The second locking projection 24aA is provided over the entire circumferential length of the fitted portion 24A. The second locking projection 24aA is locked to the first locking projection 21fA from below the first locking projection 21fA.

A protrusion 24bA is formed at the lower end of the fitted portion 24A, protruding outward in the radial direction. A circumferential groove 24cA is formed at the upper part of the fitted portion 24A. The circumferential groove 24cA opens on the outer peripheral surface of the fitted portion 24A and extends circumferentially around the entire length of the outer peripheral surface of the fitted portion 24A. A sliding portion 24dA is embedded in the circumferential groove 24cA. The sliding portion 24dA extends around the entire circumference within the sliding portion 24dA. The sliding portion 24dA is made of a material that is softer than the material of the fixed shaft member 23aA (e.g., PP, etc.), has a lower elastic modulus than the fixed shaft member 23aA, and has a higher friction coefficient than the fixed shaft member 23aA. The sliding contact portion 24dA is formed of a thermoplastic resin such as elastomer, and is fixed to the fixed shaft member 23aA by two-color molding together with the fixed shaft member 23aA. However, the sliding contact portion 24dA may be formed of, for example, nitrile rubber, butyl rubber, or silicone rubber, and the sliding contact portion 24dA may be fixed to the fixed shaft member 23aA by injection molding the fixed shaft member 23aA with the sliding contact portion 24dA as an insert. The sliding contact portion 24dA may be interposed between the sleeve 11A and the exterior body 21A.

The base portion 25A protrudes radially inward from the upper opening edge of the mating portion 24A. The base portion 25A is formed in a circular ring shape that is arranged coaxially with the container axis O. The upper opening edge of the mating portion 21bA is close to or abuts against the lower surface of the inner periphery of the base portion 25A from below.

The inner transmission shaft 26A extends upward from the inner peripheral edge of the base portion 25A. The inner transmission shaft 26A is formed in a cylindrical shape arranged coaxially with the container axis O. An inner spiral groove 26aA is formed on the outer peripheral surface of the inner transmission shaft 26A. The inner spiral groove 26aA extends spirally upward in the payout direction. In this embodiment, the inner spiral groove 26aA is formed in two stripes. However, the inner spiral groove 26aA may be one stripe or three or more stripes.

As shown in Figures 13 and 15, the insertion portion 27A is formed in a cylindrical shape arranged coaxially with the container axis O. When the fitting portion 21bA is fitted into the fitting portion 24A, the insertion portion 27A is inserted into the fitting portion 21bA. An engaged portion 27aA is formed in the insertion portion 27A. The engaged portion 27aA protrudes radially outward from the insertion portion 27A and extends in the vertical direction. The lower edge of the engaged portion 27aA is formed in an arc shape that protrudes downward. A plurality of engaged portions 27aA are formed at intervals in the circumferential direction on the outer circumferential surface of the insertion portion 27A, and are provided in a knurled shape in this embodiment. The number of engaged portions 27aA is greater than the number of engaging portions 21eA. When the fitting portion 21bA is fitted into the fitting portion 24A, the engaging portion 21e1A is sandwiched in the circumferential direction by the engaged portions 27aA located on both sides of the engaging portion 21e1A in the circumferential direction. On the other hand, the engaging portion 21e2A is sandwiched in the circumferential direction between the engaged portion 27aA located between the two engaging portions 21e2A and the engaged portion 27aA located on the circumferential outside of the two engaging portions 21e2A. As a result, the engaging portion 21eA and the engaged portion 27aA are engaged in the circumferential direction, thereby restricting the relative rotation of the fixed shaft member 23aA of the transmission shaft 23A with respect to the operating unit 10A.

The outer transmission shaft 23bA surrounds the inner transmission shaft 26A. A first engagement protrusion 31A that protrudes radially inward is formed at the lower end of the outer transmission shaft 23bA. The first engagement protrusion 31A is accommodated (engaged) in the inner spiral groove 26aA of the inner transmission shaft 26A. As the outer transmission shaft 23bA rotates in the circumferential direction relative to the inner transmission shaft 26A, the first engagement protrusion 31A moves spirally within the inner spiral groove 26aA, causing the outer transmission shaft 23bA to move up and down relative to the inner transmission shaft 26A. In this embodiment, two first engagement protrusions 31A are provided circumferentially spaced apart to match the number of threads of the inner spiral groove 26aA. Each first engagement protrusion 31A extends at an angle along the inner spiral groove 26aA.

An outer spiral groove (spiral groove) 32A is formed on the outer peripheral surface of the outer transmission shaft 23bA. The outer spiral groove 32A extends spirally upward in the payout direction. In this embodiment, the outer spiral groove 32A is formed in two rows. However, the outer spiral groove 32A may be formed in one row or three or more rows.

The sleeve 11A is provided inside the operating unit 10A so as to be rotatable in the circumferential direction with respect to the operating unit 10A and the transmission shaft 23A. The sleeve 11A is formed in a cylindrical shape arranged coaxially with the container axis O. The sleeve 11A is inserted inside the center piece 22A, and the lower end of the sleeve 11A is inserted between the center piece 22A and the base portion 25A. The sleeve 11A surrounds the outside of the transmission shaft 23A. The lower end opening edge of the sleeve 11A is supported by the upper surface of the protruding portion 24bA. The upper end opening edge of the sleeve 11A is located above the operating unit 10A and is inclined with respect to the container axis O. The sleeve 11A may be formed from a metal material or the like.

As shown in Figures 13 and 16, a protrusion 11aA is formed on the sleeve 11A. The protrusion 11aA is formed on the lower end of the sleeve 11A and protrudes radially inward. When housed within the circumferential groove 24cA, the protrusion 11aA engages with the upper and lower edges of the circumferential groove 24cA. As a result, the sleeve 11A is supported by the transmission shaft 23A so as to be rotatable in the circumferential direction, with its movement in the up and down directions relative to the operating unit 10A restricted.

A thin portion 11bA is formed in a portion of the sleeve 11A that is located above the protrusion 11aA. The thin portion 11bA is provided at the lower end of the sleeve 11A over the entire circumferential length.
A vertical groove 11cA is formed in a portion of the sleeve 11A located above the thin portion 11bA. The vertical groove 11cA opens on the inner peripheral surface of the sleeve 11A. The vertical groove 11cA extends in the vertical direction. The lower end of the vertical groove 11cA terminates at the thin portion 11bA at the lower end of the sleeve 11A. The upper end of the vertical groove 11cA terminates at the center of the sleeve 11A in the vertical direction. A plurality of vertical grooves 11cA (e.g., eight vertical grooves) are formed at intervals in the circumferential direction. The vertical grooves 11cA may also penetrate the sleeve 11A in the radial direction.

The middle plate 12A is provided in the sleeve 11A so as to be movable up and down relative to the sleeve 11A while its circumferential rotation relative to the sleeve 11A is restricted. The middle plate 12A includes a middle plate body 51A and a hanging tube 52A. In this embodiment, the middle plate body 51A and the hanging tube 52A are integrally formed. The middle plate 12A includes the middle plate body 51A that holds the contents and a tube extending downward from the middle plate body 51A, and the tube includes the hanging tube 52A. This will be described in detail below.
The inner plate body 51A is formed in a bottomed cylindrical shape arranged coaxially with the container axis O. The inner plate body 51A is accommodated in a portion of the sleeve 11A located above the transmission shaft 23A. A rod-shaped content is held within the inner plate body 51A. The rod-shaped content protrudes upward from the inner plate body 51A.

The hanging tube 52A extends downward from the bottom wall of the inner plate body 51A. The hanging tube 52A extends downward from the outer peripheral edge of the bottom wall of the inner plate body 51A. The hanging tube 52A is disposed between the outer peripheral surface of the transmission shaft 23A and the inner peripheral surface of the sleeve 11A. The outer diameter of the hanging tube 52A is approximately the same as the outer diameter of the inner plate body 51A. The hanging tube 52A is inserted inside the sleeve 11A and surrounds the outer transmission shaft 23bA.
18, the outer peripheral surface of the hanging tube 52A is in close proximity to or in contact with the inner peripheral surface of the sleeve 11A when the middle plate 12A is in the uppermost position. In this embodiment, the outer peripheral surface of the hanging tube 52A is always in close proximity to or in contact with the inner peripheral surface of the sleeve 11A regardless of the vertical position of the middle plate 12A.

A second engagement protrusion (engagement protrusion) 52aA that protrudes radially inward is formed at the lower end of the hanging tube 52A. The second engagement protrusion 52aA is accommodated (engaged) within the outer spiral groove 32A. As the hanging tube 52A rotates in the circumferential direction relative to the outer transmission shaft 23bA, the second engagement protrusion 52aA moves spirally within the outer spiral groove 32A, causing the hanging tube 52A to move up and down relative to the outer transmission shaft 23bA. In this embodiment, two second engagement protrusions 52aA are provided circumferentially spaced apart to match the number of threads of the outer spiral groove 32A. Each second engagement protrusion 52aA extends at an angle along the outer spiral groove 32A.

The hanging tube 52A is formed with a slit 52bA. The slit 52bA penetrates the hanging tube 52A in the radial direction and extends in the up-down direction. The slit 52bA opens on the lower end opening edge of the hanging tube 52A. A plurality of slits 52bA (e.g., two) are formed at intervals in the circumferential direction. As a result, at least the lower part of the hanging tube 52A is divided into two in the circumferential direction by the slit 52bA, and is easily elastically deformed in the radial direction. Therefore, when the injection-molded inner plate 12A is released, the lower part of the hanging tube 52A is elastically deformed in the radial direction, making it easier for the core to climb over the second engagement protrusion 52aA downward.

The hanging tube 52A is formed with a regulating portion 52cA that circumferentially engages with the sleeve 11A to regulate the rotation of the middle plate 12A relative to the sleeve 11A. The regulating portion 52cA is formed on the outer peripheral surface of the hanging tube 52A. The regulating portion 52cA protrudes radially outward from the hanging tube 52A and extends in the vertical direction. The vertical length of the regulating portion 52cA is shorter than the length of the vertical groove 11cA. In the illustrated example, the lower edge of the regulating portion 52cA reaches the lower edge of the hanging tube 52A. The upper edge of the regulating portion 52cA is located below the upper edge of the slit 52bA and reaches the middle part of the hanging tube 52A. A plurality of regulating portions 52cA (e.g., four) are formed at intervals in the circumferential direction. The number of the regulating portions 52cA is smaller than the vertical groove 11cA. However, the number of restriction portions 52cA and vertical grooves 11cA can be changed as appropriate.

Each regulating portion 52cA is accommodated (engaged) in the corresponding vertical groove 11cA. The regulating portion 52cA moves up and down within the vertical groove 11cA in accordance with the up and down movement of the middle plate 12A relative to the sleeve 11. The regulating portion 52cA restricts the rotation of the middle plate 12A relative to the sleeve 11A by abutting against the inner surface (surface facing the circumferential direction) of the vertical groove 11cA. In other words, the middle plate 12A is provided so as to be able to move up and down relative to the sleeve 11A while its rotation relative to the sleeve 11A is restricted by the regulating portion 52cA. As a result, the middle plate 12A is provided inside the sleeve 11A so as to be able to move up and down relative to the sleeve 11A in accordance with the rotation of the sleeve 11A relative to the transmission shaft 23A.

The cap 13A is formed in a cylindrical shape with a top that is arranged coaxially with the container axis O. The cap 13A is removably attached to the top of the inner fitting 22A with the top of the sleeve 11A inserted inside.

Next, the operation of the dispensing container 1A described above will be described. In the following explanation, first, a method of using the dispensing container 1A will be described.
When using the dispensing container 1A, first, the cap 13A is removed from the top of the center piece 22A. Next, the sleeve 11A and the exterior body 21A (peripheral wall 21gA) are grasped, and the operating part 10A and the sleeve 11A are rotated relative to each other in the dispensing direction. At this time, since the center piece 22A and the fixed shaft member 23aA are attached to the exterior body 21A so as not to rotate relative to each other, the exterior body 21A, the center piece 22A, and the fixed shaft member 23aA rotate together. Meanwhile, since the sleeve 11A and the center plate 12A are attached to each other so as not to rotate relative to each other, the sleeve 11A and the center plate 12A rotate together.

When the operating part 10A and the sleeve 11A are rotated relative to each other, at least one of the following occurs: the inner transmission shaft 26A and the outer transmission shaft 23bA rotate together relative to the hanging tube 52A, or the inner transmission shaft 26A rotates relative to the outer transmission shaft 23bA.

When the inner transmission shaft 26A and the outer transmission shaft 23bA rotate together relative to the hanging tube 52A, the second engagement protrusion 52aA moves spirally within the outer spiral groove 32A while engaged within the outer spiral groove 32A, causing the hanging tube 52A (middle plate 12A) to rise relative to the transmission shaft 23A. In this specification, the operation in which the middle plate 12A rises due to the relative rotation of the transmission shaft 23A and the hanging tube 52A in the payout direction is referred to as the "first operation."

When the inner transmission shaft 26A rotates relative to the outer transmission shaft 23bA, the first engagement protrusion 31A, engaged within the inner spiral groove 26aA, moves spirally within the inner spiral groove 26aA, causing the outer transmission shaft 23bA to rise relative to the inner transmission shaft 26A. At this time, the second engagement protrusion 52aA is pushed up via the inner surface of the outer spiral groove 32A, causing the middle plate 12A to rise together with the outer transmission shaft 23bA. This operation in which the inner transmission shaft 26A and the outer transmission shaft 23bA rotate relative to each other in the payout direction, causing the middle plate 12A to rise together with the outer transmission shaft 23bA, is referred to in this specification as the "second operation."

In other words, as shown in Figures 13 and 18, when the operating part 10A and the sleeve 11A are rotated relative to each other in the dispensing direction, the inner tray 12A rises due to at least one of the first and second actions. This causes the rod-shaped contents to be dispensed upward from the upper opening of the sleeve 11A. Which of the first and second actions occurs varies depending on factors such as frictional resistance between the various components. However, regardless of which action takes precedence, the rod-shaped contents are dispensed, allowing the user to use the rod-shaped contents. It should be noted that both the first and second actions may occur simultaneously.

When the middle plate 12A rises relative to the sleeve 11A, the regulating portion 52cA is guided within the vertical groove 11cA. This restricts the rotation of the middle plate 12A relative to the sleeve 11A, and the middle plate 12A rises relative to the sleeve 11A. The regulating portion 52cA comes into contact with the upper edge of the vertical groove 11cA, restricting the rise of the middle plate 12A relative to the sleeve 11A. This allows the middle plate 12A to reach the uppermost position.

When lowering the middle plate 12A, the operating part 10A and the sleeve 11A are rotated relative to each other in the storage direction. Then, the inner transmission shaft 26A and the outer transmission shaft 23bA rotate integrally relative to the hanging tube 52A, or the inner transmission shaft 26A rotates relative to the outer transmission shaft 23bA, causing the middle plate 12A to lower relative to the sleeve 11A. That is, when the middle plate 12A lowers relative to the sleeve 11A, the regulating part 52cA is guided into the vertical groove 11cA. After the rotation of the middle plate 12A relative to the sleeve 11A is regulated, the middle plate 12A lowers relative to the sleeve 11A. The lower end of the regulating part 52cA enters the thin-walled part 11bA, thereby restricting the lowering of the middle plate 12A relative to the sleeve 11A. As a result, the middle plate 12A reaches the lowest position.

13 and 19, in the dispensing container 1A described above, a cartridge 101A, which is a combination of a sleeve 11A, a center plate 12A, and a transmission shaft 23A, is detachably attached to an operating part 10A, which is a combination of an outer body 21A and a center piece 22A. A method for attaching and detaching (replacing) the cartridge 101A to the operating part 10A will be described below.
First, to assemble the cartridge 101A to the operating unit 10A, the cartridge 101A is inserted into the operating unit 10A through the upper end opening of the inner member 22A of the operating unit 10A. Then, the second locking projection 24aA of the mating portion 24A comes into contact with the first locking projection 21fA of the mating portion 21bA from above, and in this state, the cartridge 101A is pushed downwardly relative to the operating unit 10A so that the engaging portion 21eA and the mating portion 27aA do not overlap in a plan view. In this embodiment, since the mating portion 27aA is formed in a knurled shape, the cartridge 101A can be pushed downwardly relative to the operating unit 10A without circumferential alignment.

Then, the second locking projection 24aA climbs downward over the first locking projection 21fA, and the second locking projection 24aA is locked to the first locking projection 21fA from below. This causes the engaging portion 21bA to be undercut-fitted into the engaging portion 24A. Thereafter, the engaging portion 24A approaches or abuts against the upper surface of the bottom wall 21aA, completing the insertion of the cartridge 101A. In this state, the vertical movement of the cartridge 101A relative to the operating unit 10A is restricted.

On the other hand, in the process in which the second locking projection 24aA passes over the first locking projection 21fA downward, the engaging portion 21eA enters between the adjacent engaged portions 27aA. This causes the engaging portion 21eA and the engaged portion 27aA to engage in the circumferential direction. As a result, the circumferential movement of the fixed shaft member 23aA relative to the exterior body 21 is restricted. In addition, the engaging portion 21eA enters between the adjacent engaged portions 27aA, so that the insertion portion 27A is inserted inside the fitting portion 21bA. This causes the fitting portion 21bA to be radially sandwiched between the inserting portion 27A and the fitted portion 24A. As a result, the radial movement of the cartridge 101A relative to the operating portion 10A is restricted.
This completes the installation of the cartridge 101A into the operation unit 10A.

When the cartridge 101A is to be removed from the operating unit 10A, for example when the bar-shaped contents have been used up, the cartridge 101A is pulled upward relative to the operating unit 10A. Then, the second locking projection 24aA moves upward over the first locking projection 21fA, and the engagement between the engaged portion 24A and the engaging portion 21bA is released. In addition, by pulling the cartridge 101A up relative to the operating unit 10A, the engaging portion 21bA comes out from between the engaged portion 24A and the insertion portion 27A, and the engaging portion 21eA comes out from between the engaged portions 27aA adjacent to each other in the circumferential direction.
As a result, the cartridge 101A is removed from the operation unit 10A.

Here, in the dispensing container 1A of this embodiment, the middle plate 12A comprises a middle plate main body 51A that holds rod-shaped contents and a hanging tube 52A extending downward from the middle plate main body 51A, and the middle plate main body 51A and the hanging tube 52A are formed as a single unit.
According to this configuration, by forming the hanging tube 52A integrally with the middle plate main body 51A, the number of parts can be reduced compared to the conventional case in which a separate rotation regulating part is provided between the sleeve and the middle plate, thereby making it possible to provide a low-cost dispensing container 1A.

In the dispensing container 1A of this embodiment, the hanging tube 52A is provided with both a second engaging protrusion 52aA that engages with the outer spiral groove 32A of the transmission shaft 23A, and a regulating portion 52cA that circumferentially engages with the sleeve 11A to regulate the rotation of the middle plate 12A relative to the sleeve 11A.
With this configuration, compared to a double-cylinder structure that includes, for example, a cylinder provided with a second engagement protrusion and a cylinder provided with a regulating portion, it is possible to keep the outer diameter of the inner plate 12A small, thereby making it possible to slim down the dispensing container 1A.

For example, when the middle plate 12A is at the uppermost position, if the operating part 10A and the sleeve 11A are rotated relative to each other in the extension direction, the hanging tube 52A may deform radially outward and the second engagement protrusion 52aA may overcome the upper end of the outer spiral groove 32A (i.e., an overrun of the second engagement protrusion 52aA may occur).
In contrast, in dispensing container 1A of the present embodiment, when inner plate 12A is at the uppermost position, the outer peripheral surface of hanging tube 52A is close to or in contact with the inner peripheral surface of sleeve 11A.
According to this configuration, when inner plate 12A is at the uppermost position, it is possible to restrict radially outward deformation of hanging tube 52A by the inner circumferential surface of sleeve 11A, and it is possible to prevent second engagement protrusion 52aA from climbing over the upper end of outer spiral groove 32A. As a result, it is possible to provide a dispensing container 1A with excellent reliability.

In the dispensing container 1A of this embodiment, a vertical groove 11cA extending in the vertical direction is formed in the sleeve 11A, and a regulating portion 52cA is arranged to be able to move up and down within the vertical groove 11cA and abuts against the inner surface of the vertical groove 11cA in the circumferential direction, thereby regulating the rotation of the middle plate 12A relative to the sleeve 11A.
According to this configuration, the inner plate 12A can be smoothly moved up and down relative to the sleeve 11A.

In the dispensing container 1A of this embodiment, the operating unit 10A has an engaging portion 21bA extending upward from the bottom wall 21aA, and the transmission shaft 23A has a fitted portion 24A that is fitted into the engaging portion 21bA in the vertical direction.
According to this configuration, when attaching the cartridge 101A to the operating unit 10A, the cartridge 101A is inserted into the inside of the operating unit 10A through the upper end opening of the operating unit 10A. As a result, the fitting portion 21bA is inserted into the fitted portion 24A in the vertical direction, and the fitting portion 21bA is fitted into the fitted portion 24A. On the other hand, when removing the cartridge 101A from the operating unit 10A, the cartridge 101A is pulled upward with respect to the operating unit 10A. As a result, the fitting portion 21bA is disengaged from the fitted portion 24A. That is, with the dispensing container 1A of this embodiment, the cartridge 101A can be easily attached to and detached from the operating unit 10A simply by inserting and removing the cartridge 101A from the operating unit 10A.

The above describes preferred embodiments of the present invention, but the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the scope of the attached claims.

In the above embodiment, the transmission shaft 23A includes the inner transmission shaft 26A and the outer transmission shaft 23bA, but the present invention is not limited to this configuration. The transmission shaft 23A may be configured such that the inner transmission shaft 26A, the outer transmission shaft 23bA, and the base portion 25A are integrally formed.
In the above-described embodiment, the configuration in which the operating unit includes the exterior body 21A and the intermediate part 22A has been described, but the configuration is not limited to this. The operating unit may include only the exterior body 21A.
In the above embodiment, the fitting portion 21bA is formed on the operating portion (one member) 10A, and the fitted portion 24A is formed on the transmission shaft (the other member) 23A. However, the present invention is not limited to this configuration. The fitting portion may be formed on the transmission shaft (one member) 23A, and the fitted portion may be formed on the operating portion (the other member) 10A.

In the above-described embodiment, the fitting portion and the fitted portion according to the present invention are described as being circular (cylindrical) in plan view, but the present invention is not limited to this configuration. The fitting portion and the fitted portion may be polygonal in plan view, etc., corresponding to each other. In this case, when the fitting portion and the fitted portion are fitted to each other, the corresponding corners engage with each other in the circumferential direction, thereby restricting the relative rotation in the circumferential direction between the fitting portion and the fitted portion. In other words, the corresponding corners form a rotation prevention portion.
In the above-described embodiment, the fitting portion, the fitted portion, and the insertion portion are formed in a cylindrical shape. However, the present invention is not limited to this configuration. As long as at least the fitted portion is cylindrical, the fitting portion may be columnar or the like.

In the above-described embodiment, the vertical groove 11cA is formed in the sleeve 11, and the restricting portion 52cA is formed in the hanging tube 52A. However, the present invention is not limited to this configuration. The vertical groove may be formed in the hanging tube 52A, and the restricting portion may be formed in the sleeve 11A.
In the above embodiment, the cartridge 101A is configured to be detachable from the operation unit 10A, but the present invention is not limited to this configuration. The dispensing container 1A may be configured such that the inner plate 12A and the sleeve 11A cannot be detached from the operation unit 10A (they are disposable). In this case, the inner transmission shaft 26A may be formed integrally with the bottom wall 21aA of the exterior body 21A.
