[0020] An embodiment of a dispensing container and a cartridge for a dispensing container (sometimes simply referred to as a cartridge in this specification) according to the present invention will be described below with reference to the drawings. In the following description, the up-down direction refers to the direction along the central axis O shown in the drawings (the central axis of the rotor 5 described below). The radial direction refers to the direction perpendicular to the central axis O in a plane perpendicular to the central axis O, and the circumferential direction refers to the direction revolving around the central axis O in this plane.
[0021] First, the structure of the illustrated dispensing container 1 will be described. As shown in Figures 1 and 2, the dispensing container 1 of this embodiment is made up of a base 2, a cartridge 7, and a cap 10. The base 2 is made up of a base body 3, a bottom cover 4, a rotor 5, and a shaft 6, and the cartridge 7 is made up of a cartridge body 8 and an inner tray 9. All of these components are shaped around a central axis O, and in this embodiment, all are made of synthetic resin.
[0022] The base body 3 has a cylindrical lower outer peripheral wall 3a. The lower outer peripheral wall 3a has a flat shape (a track shape in this embodiment) in plan view, similar to the upper outer peripheral wall 8a of the cartridge body 8 shown in FIG. 5. A fitting wall 3b having a thickness thinner than the lower outer peripheral wall 3a is provided at the lower end of the lower outer peripheral wall 3a. An opening 3c penetrating the lower outer peripheral wall 3a in the radial direction is provided at a portion of the vertical middle portion of the lower outer peripheral wall 3a located in the short direction in plan view, as shown in FIG. 2. Furthermore, a pair of holes 3d penetrating the lower outer peripheral wall 3a in the radial direction are provided at a portion of the upper portion of the lower outer peripheral wall 3a located in the long direction in plan view, as shown in FIG. 1.
[0023] The bottom cover 4 is formed in a track shape in plan view, similar to the lower outer peripheral wall 3a. A fitting recess 4a that fits into the fitting wall 3b is provided on the outer edge of the bottom cover 4. A circular inner annular wall 4b and a circular outer annular wall 4c located radially outward of the inner annular wall 4b are provided in the center of the bottom cover 4.
[0024] As shown in FIGS. 1, 2, and 3, the rotor 5 includes a cylindrical wall 5a extending along the central axis O. The cylindrical wall 5a has a circular outer peripheral surface and a polygonal inner peripheral surface (a regular hexagonal shape in this embodiment). The outer diameter of the cylindrical wall 5a is slightly smaller than the inner diameter of the inner annular wall 4b, and the cylindrical wall 5a is supported in the radial direction by the inner annular wall 4b. That is, the rotor 5 is rotatably supported relative to the bottom cover 4 by the cylindrical wall 5a and the inner annular wall 4b. A stopper 5b protruding radially inward is provided above the cylindrical wall 5a. An annular restricting wall 5c is provided above the stopper 5b.
[0025] The rotor 5 also includes an operation wall 5d that extends radially outward from the cylindrical wall 5a and then downward. As shown in Fig. 2, the operation wall 5d is located where the opening 3c is provided, and the outer circumferential surface of the operation wall 5d is exposed to the outside through the opening 3c. As shown in Fig. 1, the lower end of the operation wall 5d is located radially inside the outer annular wall 4c, and the operation wall 5d is supported in the radial direction by the outer annular wall 4c.
[0026] As shown in Figures 1, 2, and 4, the shaft 6 includes a cylindrical tubular portion 6a extending along a central axis O. The outer peripheral surface of the tubular portion 6a is provided with a spirally extending male thread portion 6b. The upper portion of the tubular portion 6a is provided with a first protrusion 6c that protrudes radially inward from the inner peripheral surface of the tubular portion 6a. The upper portion of the tubular portion 6a is also provided with a slit 6d that cuts the tubular portion 6a from top to bottom. This allows the upper portion of the tubular portion 6a to elastically deform radially outward.
[0027] The shaft 6 also includes a plate-shaped retaining portion 6e extending radially outward from the lower end of the cylindrical portion 6a. In this embodiment, the retaining portion 6e also functions to prevent rotation relative to the inner circumferential surface of the cylindrical wall 5a. To achieve this rotation prevention function, the retaining portion 6e in this embodiment is a regular hexagon corresponding to the shape of the inner circumferential surface of the cylindrical wall 5a. The shape of the inner circumferential surface of the cylindrical wall 5a and the shape of the retaining portion 6e are not limited to a regular hexagon, but may be a triangle or a square. The retaining portion 6e is sized to be inserted into the cylindrical wall 5a. In other words, when the rotor 5 is rotated with the retaining portion 6e inserted into the cylindrical wall 5a, the shaft 6 rotates with the rotor 5. In this state, the shaft 6 can move relative to the rotor 5 in a direction along the central axis O, but because the retaining portion 6e is larger than the stopper 5b, the shaft 6 will not slip out upward relative to the rotor 5.
[0028] The portion of the shaft 6 where the cylindrical portion 6a, the first protrusion 6c, and the slit 6d are provided corresponds to the "first engagement portion" in this specification, etc. The portion of the shaft 6 where the cylindrical portion 6a and the male thread portion 6b are provided corresponds to the "first screw-engagement portion" in this specification, etc.
[0029] As shown in FIG. 5( a), the cartridge body 8 has a cylindrical upper outer peripheral wall 8a that has a track shape in a plan view. A horizontally extending plate-like wall 8b is provided at the lower end of the upper outer peripheral wall 8a. A circular through-hole 8c is provided in the center of the plate-like wall 8b, centered on the central axis O. The plate-like wall 8b also has a pair of elastic pieces 8d on the longitudinally outer side of the circular through-hole 8c in a plan view. In this embodiment, the elastic pieces 8d are shaped so that one end is connected to the plate-like wall 8b, extends radially inward from the circular through-hole 8c, and then extends downward. The downward-extending portion of the elastic pieces 8d is elastically deformable so as to bend radially outward. A spirally extending female thread 8e is provided on the inner peripheral surface of the downward-extending portion.
[0030] Furthermore, the plate-shaped wall 8b has a rectangular through-hole 8f, which is rectangular in plan view, located longitudinally outward of the elastic piece 8d. A cartridge body side engaging portion 8g is provided inside the rectangular through-hole 8f. In this embodiment, the cartridge body side engaging portion 8g is shaped like a claw, as shown in FIG. 5(b). The cartridge body side engaging portion 8g is connected to the plate-shaped wall 8b on the longitudinally outer side thereof and is elastically deformable radially outward. As shown in FIG. 5(a), a thin, narrow weakened portion 8h is provided inside the rectangular through-hole 8f, positioned in the lateral direction of the plate-shaped wall 8b and connecting the cartridge body side engaging portion 8g to the plate-shaped wall 8b. The weakened portion 8h is rupturable, and when ruptured, the cartridge body side engaging portion 8g is elastically deformable. However, when the weakened portion 8h is connected to the cartridge body side engaging portion 8g and the plate-shaped wall 8b, elastic deformation of the cartridge body side engaging portion 8g is suppressed.
[0031] The portion of the cartridge body 8 where the elastic piece 8d and the female screw portion 8e are provided corresponds to the "second screw portion" in this specification and the like.
[0032] The cartridge body 8 further includes a cylindrical guide 8j extending downward from the plate-like wall 8b. A claw 8k is provided on the longitudinally outer side of the guide 8j in a plan view. The claw 8k is elastically deformable radially inward and has a bulging radially outer side surface. As shown in FIG. 1, the radially outward bulging portion of the claw 8k is inserted into the hole 3d from the radially inner side. The upper surface of this bulging portion extends horizontally and engages with the upper surface of the hole 3d. The lower surface of this bulging portion is provided with an inclined surface 8m that slopes downward and radially inward.
[0033] The inner tray 9 is located radially inward of the upper outer peripheral wall 8a and includes a plate-shaped inner tray lower wall 9a that is slightly smaller than the upper outer peripheral wall 8a in plan view and has a track-like shape. An inner tray outer peripheral wall 9b extends upward along the inner peripheral surface of the upper outer peripheral wall 8a at the outer edge of the inner tray lower wall 9a. An inner tray inner peripheral wall 9c extends upward radially inward of the inner tray outer peripheral wall 9b. Although not shown, the inner tray 9 holds a stick-shaped content. In this embodiment, when the inner tray 9 is moved downward as shown in FIG. 1, the shape of the stick-shaped content before use is approximately the same as or lower than the upper end of the upper outer peripheral wall 8a, and in plan view, it has a track-like shape approximately the same as the inner tray lower wall 9a.
[0034] As shown in the partially enlarged view of Figure 1, the inner tray lower wall 9a is provided with a shaft-like portion 9d that extends downward along the central axis O and has a circular outer shape. As shown in Figure 1, the outer diameter of the shaft-like portion 9d is smaller than the inner diameter of the cylindrical portion 6a of the shaft body 6. A second protrusion 9e that protrudes radially outward is provided on the outer peripheral surface of the shaft-like portion 9d.
[0035] The portion of the inner tray 9 where the shaft-like portion 9d and the second protrusion 9e are provided corresponds to the "second engagement portion" in this specification and the like.
[0036] Furthermore, the inner tray lower wall 9a is provided with an inner tray side engaging portion 9f on the longitudinally outer side of the shaft portion 9d in a plan view. In this embodiment, the inner tray side engaging portion 9f is shaped like a claw as shown in Figure 1 and can be engaged with the cartridge body side engaging portion 8g.
[0037] The cap 10 has a plate-shaped top wall 10a located above the cartridge body 8, and a cap outer peripheral wall 10b extending downward from the outer edge of the top wall 10a and surrounding the upper outer peripheral wall 8a, the lower outer peripheral wall 3a, the claws 8k, etc. The cap outer peripheral wall 10b is configured to be detachably fitted to the lower outer peripheral wall 3a, and the cap 10 is held by the base body 3.
[0038] Next, a method of using the dispensing container 1 will be described with reference to FIGS. 6 to 10. The left-hand side view of FIG. 6, taken along the central axis O, shows the state in which the cap 10 has been removed from the state shown in FIG. 1. This left-hand view also shows the state immediately after the cartridge 7 has been attached to the base 2. As shown in this left-hand view, when the cartridge 7 is attached to the base 2, the claw portion 8k engages with the hole 3d, preventing the cartridge 7 from accidentally coming off the base 2. Furthermore, the second protrusion 9e is positioned above the first protrusion 6c, and the two are in a disengaged state. However, the inner tray engaging portion 9f engages with the cartridge body engaging portion 8g, preventing the inner tray 9 from coming off the cartridge body 8. Furthermore, in this state, the weakened portion 8h shown in FIG. 5(a) is connected to the cartridge body engaging portion 8g. That is, elastic deformation of the cartridge body-side engaging portion 8g is suppressed, and the inner tray-side engaging portion 9f and the cartridge body-side engaging portion 8g are more firmly engaged, which more reliably prevents the inner tray 9 from slipping out of the cartridge body 8. In this state, the male thread portion 6b and the female thread portion 8e are threadedly engaged. In addition, the lower end of the elastic piece 8d is located radially inside the restricting wall 5c, and the elastic deformation of the elastic piece 8d radially outward is restricted by the restricting wall 5c.
[0039] Next, the rotor 5 is rotated in a direction that causes the male threaded portion 6b to rise relative to the female threaded portion 8e. As described above, when the rotor 5 is rotated, the shaft 6 also rotates, and the engaged male threaded portion 6b and female threaded portion 8e cause the shaft 6 to rise relative to the cartridge body 8, as shown on the right side of FIG. 6, with the center axis O as the base point. As described above, the upper part of the cylindrical portion 6a can be elastically deformed radially outward by the slit 6d. Therefore, as the shaft 6 rises, the first protrusion 6c overcomes and engages with the second protrusion 9e. This allows the inner tray 9 to move up and down together with the shaft 6 in response to the rotation of the rotor 5, so that a stick-shaped content (not shown) held in the inner tray 9 can be dispensed from the cartridge body 8 and applied to the application target. After application, the stick-shaped content can be dispensed and stored inside the cartridge body 8.
[0040] Furthermore, when the inner tray 9 is first raised, the cartridge body-side engaging portion 8g that engages with the inner tray-side engaging portion 9f is also raised, causing the weakened portion 8h shown in Fig. 5(a) to break and making the cartridge body-side engaging portion 8g elastically deformable. That is, when the inner tray 9 is lowered after the weakened portion 8h is broken, the cartridge body-side engaging portion 8g elastically deforms and becomes disengaged from the inner tray-side engaging portion 9f, as shown on the right side of Fig. 9 with the central axis O as the base point, so that the cartridge body-side engaging portion 8g does not hinder the rise of the inner tray 9.
[0041] As shown in FIG. 7 , after the inner tray 9 is advanced to the top end of the cartridge body 8 and the rod-shaped contents are used up, the used cartridge 7 can be replaced with a new cartridge 7. To perform the replacement, as shown in FIG. 8 , the claws 8k of the used cartridge 7 attached to the base 2 are pressed radially inward. This causes the claws 8k to bend radially inward, disengaging the claws 8k from the holes 3d, allowing the cartridge 7 to be pulled up relative to the base 2. When the cartridge 7 begins to be pulled up, the lower end of the elastic piece 8d rises above the restricting wall 5c, allowing the elastic piece 8d to elastically deform radially outward. Furthermore, as described above, because the first protrusion 6c engages with the second protrusion 9e, pulling up the cartridge 7 pulls up the shaft 6 along with the inner tray 9. However, when the shaft 6 is pulled up, the retaining portion 6e engages with the stopper 5b, preventing the shaft 6 from slipping outward relative to the rotor 5.
[0042] 9, as shown on the left side, the cartridge 7 is pulled up relative to the shaft 6 and the inner tray 9. At this time, the male threaded portion 6b and the female threaded portion 8e are threadedly engaged, but the elastic piece 8d elastically deforms radially outward, releasing the engagement between them, allowing the cartridge body 8 to be lifted relative to the shaft 6.
[0043] Then, as the cartridge 7 continues to be pulled up and the cartridge body 8 comes into contact with the inner plate 9 from below, the inner plate 9 is also pulled up along with the cartridge body 8, and the force with which the second protrusion 9e pulls up the first protrusion 6c causes the upper part of the cylindrical portion 6a to elastically deform radially outward, thereby releasing the engagement between the second protrusion 9e and the first protrusion 6c and allowing the inner plate 9 to be separated from the shaft 6. That is, in the dispensing container 1 of this embodiment, the only components of the cartridge 7 that can be removed from the base 2 are the cartridge body 8 and the inner plate 9.
[0044] Figure 10 shows the state in which a new cartridge 7 is attached to the base 2. The new cartridge 7 has a sheet material S attached to the upper end of the upper outer wall 8a to keep the rod-shaped contents sealed. The sheet material S may be, for example, an aluminum sheet or a synthetic resin sheet. The new cartridge 7 is then inserted into the original base body 3 with the sheet material S still attached (it may be removed first).
[0045] As described above, the lower surfaces of the claws 8k are provided with inclined surfaces 8m that slope downward and radially inward. That is, when the cartridge 7 is inserted into the base body 3, the inclined surfaces 8m come into contact with the upper end surface of the lower outer peripheral wall 3a, causing the claws 8k to bend radially inward, so that the cartridge 7 can be attached to the base body 3 without pressing the claws 8k with fingers.
[0046] Thereafter, by peeling off the attached sheet material S, the dispensing container 1 can be used as a dispensing container 1. As described above, according to the dispensing container 1 of this embodiment, the base 2 and cap 10 can be reused after the stick-shaped contents have been used, and therefore the dispensing container 1 of this embodiment is superior in terms of resource conservation and reduced environmental impact compared to conventional dispensing containers such as those disclosed in Patent Document 2.
[0047] Next, a second embodiment of a dispensing container according to the present invention will be described with reference to FIGS.
[0048] Dispensing container 21 of this embodiment is made up of a base 22, cartridge 27, and a cap (not shown) similar to cap 10 described above. Base 22 is made up of base body 23, bottom cover body 24, rotor 25, and shaft body 26, while cartridge 27 is made up of cartridge body 28 and inner tray 29. All of these components are shaped around central axis O, and in this embodiment, all are made of synthetic resin.
[0049] The base body 23 has a flat shape (a track shape in this embodiment) in a plan view, similar to the base body 3. As shown in Fig. 11 , the base body 23 includes a lower outer peripheral wall 23a, a fitting wall 3b, an opening (not shown in Fig. 11 ), and a hole 23d, which have the same configurations as the lower outer peripheral wall 3a, the fitting wall 3b, the opening 3c, and the hole 3d described above.
[0050] As shown in FIG. 12 , the bottom cover 24 is formed in a track shape in plan view and includes a fitting recess 24a and an inner annular wall 24b similar to the fitting recess 4a and inner annular wall 4b described above. An inclined portion 24d is provided radially inside the inner annular wall 24b, protruding upward from the top surface of the bottom cover 24 and shaped like an arc centered on the central axis O in plan view. In this embodiment, a pair of inclined portions 24d are provided on either side of the central axis O. Furthermore, the inclined portion 24d in this embodiment is inclined such that the height of its top surface increases counterclockwise around the central axis O in plan view. The degree of inclination of the inclined portion 24d will be described later.
[0051] As shown in Fig. 11, the rotating body 25 has a cylindrical wall 25a. Like the cylindrical wall 5a described above, the cylindrical wall 25a has a circular outer peripheral surface and a polygonal inner peripheral surface (a regular hexagonal shape in this embodiment), and the outer diameter of the cylindrical wall 25a is slightly smaller than the inner diameter of the inner annular wall 24b. That is, the rotating body 25 is rotatably supported with respect to the bottom cover 24 by the cylindrical wall 25a and the inner annular wall 24b. The rotating body 25 also has a stopper 25b, a restriction wall 25c, and an operation wall 25d. The stopper 25b, the restriction wall 25c, and the operation wall 25d have the same configurations as the stopper 5b, the restriction wall 5c, and the operation wall 5d described above.
[0052] As shown in FIGS. 11 and 13 , the shaft 26 includes a cylindrical tubular portion 26a extending along a central axis O. A spirally extending male thread portion 26b is provided on the outer peripheral surface of the tubular portion 26a. The male thread portion 26b is threadedly engaged with a female thread portion 28e (described later) provided on the cartridge body 28. The male thread portion 26b in this embodiment is a double-threaded thread with a pitch of 3 mm (i.e., a lead of 6 mm). Like the inclined portion 24d described above, the male thread portion 26b in this embodiment extends upward counterclockwise around the central axis O in a plan view. The inclination of the inclined portion 24d is steeper than that of the male thread portion 26b. Specifically, when the inclination of the inclined portion 24d is converted into a double-threaded thread, the pitch is equivalent to 6 mm (i.e., a lead of 12 mm). That is, the inclination of inclined portion 24d is such that when shaft 26 rotates once along inclined portion 24d, shaft 26 moves 12 mm in the direction along central axis O. Note that, because the height of inclined portion 24d in this embodiment is low, the actual movement distance when shaft 26 moves along inclined portion 24d is less than 12 mm. In contrast, when shaft 26 rotates once with male thread portion 26b threaded into female thread portion 28e, shaft 26 moves 6 mm in the direction along central axis O.
[0053] Here, as shown in Figure 15, the upper end of the thread in the male thread portion 26b is referred to as thread upper end 26f. Furthermore, a protrusion 26g is provided in the thread groove portion of the male thread portion 26b below thread upper end 26f, protruding radially outward from the cylindrical portion 26a. As shown in Figure 15, the end of protrusion 26g on the left side in the direction of rotation in plan view is lower in the vertical direction, and the gap between this end and thread upper end 26f in the vertical direction is wide. On the other hand, the end of protrusion 26g on the right side in the direction of rotation in plan view is higher in the vertical direction, and the gap between this end and thread upper end 26f in the vertical direction is narrow.
[0054] 11, shaft 26 is provided with a first protrusion 26c that protrudes radially inward from the inner circumferential surface of cylindrical portion 26a at the top of cylindrical portion 26a. Although shaft 26 does not have slit 6d that is provided in shaft 6 described above, shaft 26 may be provided with such slit 6d.
[0055] Furthermore, shaft 26 is provided with retaining portion 26e that connects to cylindrical portion 26a at its lower end. Retaining portion 26e is a polygonal cylindrical shape that is larger in outer diameter than cylindrical portion 26a, and in this embodiment, is shaped like a regular hexagon to correspond to the shape of the inner circumferential surface of cylindrical wall 25a. By providing such retaining portion 26e, when rotor 25 is rotated with retaining portion 26e inserted inside cylindrical wall 25a, shaft 26 rotates together with rotor 25. Furthermore, because retaining portion 26e is larger than stopper 25b, shaft 26 does not slip out upward relative to rotor 25.
[0056] A plate-shaped rib 26h is provided inside the retaining portion 26e. A pair of ribs 26h are provided on either side of the central axis O. As shown in FIG. 11(b), the rib 26h is provided at a position overlapping the inclined portion 24d in a bottom view. Note that in FIG. 11(b), the inclined portion 24d is shown hatched to clearly show the positional relationship between the inclined portion 24d and the rib 26h. In the state shown in FIG. 11, the shaft 26 is at its lowest position with the retaining portion 26e in contact with the upper surface of the bottom cover 24, and the rib 26h in contact with the upper surface below the inclined portion 24d.
[0057] The portion of the shaft 26 where the cylindrical portion 26a and the first protrusion 26c are provided corresponds to the "first engagement portion" in this specification, etc. The portion of the shaft 26 where the cylindrical portion 26a and the male thread portion 26b are provided corresponds to the "first screw-engagement portion" in this specification, etc.
[0058] As shown in FIG. 14( a), the cartridge body 28 includes a cylindrical upper outer peripheral wall 28a that has a track-like shape in plan view, and a plate-like wall 28b that is connected to the lower end of the upper outer peripheral wall 28a and extends horizontally. A circular through-hole 28c centered on the central axis O is provided in the center of the plate-like wall 28b. The plate-like wall 28b also includes a pair of elastic pieces 28d on the longitudinal outward side of the circular through-hole 28c in plan view. In this embodiment, each elastic piece 28d has one end connected to the plate-like wall 28b, extends radially inward from the end, and then extends downward. The downward-extending portion is elastically deformable so as to bend radially outward. A spirally extending female thread 28e is provided on the inner peripheral surface of the downward-extending portion.
[0059] Furthermore, the plate-shaped wall 28b is provided with a rectangular through-hole 28f, which is rectangular in plan view, on the longitudinal outward side of the elastic piece 28d in a plan view. A claw-shaped cartridge body side engaging portion 28g is provided inside the rectangular through-hole 28f. The cartridge body side engaging portion 28g is connected to the plate-shaped wall 28b on the longitudinal outward side of the plate-shaped wall 28b and is elastically deformable radially outward. As shown in FIG. 14(a), a thin, narrow weakened portion 28h is provided inside the rectangular through-hole 28f, positioned in the lateral direction of the plate-shaped wall 28b and connecting the cartridge body side engaging portion 28g and the plate-shaped wall 28b. The weakened portion 28h is rupturable, and when ruptured, the cartridge body side engaging portion 28g is elastically deformable. However, when the weakened portion 28h is connected to the cartridge body side engaging portion 28g and the plate-shaped wall 28b, elastic deformation of the cartridge body side engaging portion 28g is suppressed.
[0060] The portion of the cartridge body 28 where the elastic piece 28d and the female screw portion 28e are provided corresponds to the "second screw portion" in this specification and the like.
[0061] Furthermore, the cartridge body 28 is provided with a guide 28j, a claw portion 28k, and an inclined surface 28m, which have the same configuration as the guide 8j, the claw portion 8k, and the inclined surface 8m described above.
[0062] The inner tray 29 includes the inner tray lower wall 29a, the inner tray outer wall 29b, the inner tray inner wall 9c, the shaft-like portion 29d, the second protrusion 29e, and the inner tray-side engaging portion 29f, which have the same configurations as the inner tray lower wall 9a, the inner tray outer wall 9b, the inner tray inner wall 9c, the shaft-like portion 9d, the second protrusion 9e, and the inner tray-side engaging portion 9f described above. Note that the portion of the inner tray 29 where the shaft-like portion 29d and the second protrusion 29e are provided corresponds to the "second engaging portion" in this specification.
[0063] Next, the use of the dispensing container 21 will be described with reference to the drawings. Here, FIG. 11 shows the state immediately after the cartridge 27 is attached to the base 22. As shown in the figure, when the cartridge 27 is attached to the base 22, the claw portion 28k engages with the hole portion 23d, preventing the cartridge 27 from accidentally coming off the base 22. Furthermore, the second protrusion 29e is positioned above the first protrusion 26c, and the two are disengaged. Meanwhile, the inner tray engaging portion 29f engages with the cartridge body engaging portion 28g, preventing the inner tray 29 from coming off the cartridge body 28. Furthermore, in this state, the weakened portion 28h shown in FIG. 14(a) is connected to the cartridge body engaging portion 28g. That is, elastic deformation of the cartridge body engaging portion 28g is suppressed, and the inner tray engaging portion 29f and the cartridge body engaging portion 28g are more firmly engaged, thereby more reliably preventing the inner tray 29 from coming off the cartridge body 28.
[0064] Incidentally, when the cartridge 7 is attached to the base 2 as shown in FIG. 6 , the shaft 6 is inserted between the opposing elastic pieces 8d, causing the elastic pieces 8d to elastically deform radially outward, thereby causing the male threaded portion 6b and the female threaded portion 8e to thread together as shown on the left side of FIG. 6 , with the central axis O as the base point. Furthermore, when the cartridge 7 is attached to the base 2, the restricting wall 5c moves radially outward from the elastic piece 8d. Here, because the position of the shaft 6 in the rotational direction is not particularly restricted, there is a risk that, for example, the restricting wall 5c may reach the elastic piece 8d before the male threaded portion 6b and the female threaded portion 8e have completely threaded together. In this case, there is a risk of problems such as the male threaded portion 6b not threading together properly with the female threaded portion 8e or the restricting wall 5c hindering the elastically deformed elastic piece 8d from returning to its original shape.
[0065] Meanwhile, in dispensing container 21, immediately after cartridge 27 shown in Fig. 11 is attached to base 22, male thread portion 26b and female thread portion 28e are in the state shown in Fig. 15. That is, thread upper end 26f is separated from female thread portion 28e, and male thread portion 26b and female thread portion 28e are not threaded together, so the above-mentioned problem does not occur.
[0066] To thread the male thread portion 26b and the female thread portion 28e together, the rotor 25 is rotated in the direction of the arrow shown in FIG. 16(b) (clockwise in bottom view). FIG. 16 shows the state after the rotor 25 has been rotated from the state shown in FIG. 11. As described above, the shaft 26 rotates together with the rotor 25, so the shaft 26 also rotates as shown by the arrow in FIG. 15 (counterclockwise in plan view). The bottom cover 24 has an inclined portion 24d, and the shaft 26 has a rib 26h. When the shaft 26 rotates counterclockwise in plan view, the rib 26h comes into contact with the inclined portion 24d, causing the shaft 26 to rotate counterclockwise and rise. As a result, the thread top end 26f approaches the female thread portion 28e and engages with it, as shown in FIG. 17, allowing the male thread portion 26b and the female thread portion 28e to be threaded together. In this embodiment, the relationship between the inclination of the inclined portion 24d and the lead of the male thread portion 26b is set as described above, so that the distance traveled by the inclined portion 24d and the rib 26h is greater than the distance traveled by the male thread portion 26b and the female thread portion 28e. That is, although the shaft 26 begins to rise when the thread top end 26f begins to engage with the female thread portion 28e, the inclined portion 24d and the rib 26h forcibly lift the shaft 26, thereby enabling the thread top end 26f to stably engage with the female thread portion 28e. Furthermore, the thread groove of the male thread portion 26b is provided with a protrusion 26g. As shown in FIG. 15 , the end of the protrusion 26g on the left side in the direction of rotation in a plan view is lowered vertically, and the vertical gap between this end and the thread top end 26f is widened, allowing the thread top end 26f and the female thread portion 28e to smoothly engage with each other.
[0067] 18, when rotor 25 is further rotated, shaft 26 is raised relative to cartridge body 28 by male thread portion 26b and female thread portion 28e, and first protrusion 26c climbs over and engages with second protrusion 29e. In dispensing container 21 of this embodiment, rib 26h is set so as to move away from inclined portion 24d when male thread portion 26b and female thread portion 28e are completely threaded together, and therefore rib 26h and inclined portion 24d do not affect the raising of shaft 26 by male thread portion 26b and female thread portion 28e.
[0068] Further rotation of the rotor 25 also pulls up the cartridge body-side engaging portion 28g, which engages with the inner tray-side engaging portion 29f, as shown in FIG. 19. This breaks the weakened portion 28h shown in FIG. 14(a), rendering the cartridge body-side engaging portion 28g elastically deformable. Furthermore, the first protrusion 26c engages the second protrusion 29e. Therefore, the inner tray 29 can be moved up and down together with the shaft 26 in response to the rotation of the rotor 25. This allows a stick-shaped content (not shown) held in the inner tray 29 to be dispensed from the cartridge body 28 and applied to the target. After application, the stick-shaped content can be dispensed and stored inside the cartridge body 28. After the weakened portion 28h is broken, when the rotor 25 is rotated in the reverse direction to lower the inner tray 29, the cartridge body-side engaging portion 28g elastically deforms and disengages from the inner tray-side engaging portion 29f, as shown in FIG. 20, so the cartridge body-side engaging portion 28g does not impede the upward movement of the inner tray 29.
[0069] It is anticipated that if the rotor 25 is rotated excessively in the reverse direction when lowering the inner plate 29, the thread upper end 26f will come off the female thread portion 28e. On the other hand, in this embodiment, as shown in Fig. 21, the protrusion 26g is provided, and even if an attempt is made to rotate the rotor 25 excessively in the reverse direction, the protrusion 26g comes into contact with the end of the female thread portion 28e, preventing the rotor 25 from rotating excessively in the reverse direction. This prevents the thread upper end 26f from coming off the female thread portion 28e.
[0070] In dispensing container 21, once the stick-shaped contents have been used up, it is possible to replace used cartridge 27 with a new cartridge 27 in the same manner as in dispensing container 1 described above. Furthermore, the only components of cartridge 27 that are removed from base 22 are cartridge body 28 and inner plate 29; the other components can be reused, which is excellent for saving resources and reducing the burden on the environment.

For example, the configurations of the above-described embodiment may be added or deleted as appropriate, and the configurations of one embodiment may be incorporated into other embodiments. Furthermore, the effects of the above-described embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above-described effects.
[0072] For example, in the above-described embodiment, the weakened portion 8h provided on the cartridge body 8 is connected to the cartridge body-side engaging portion 8g, but a weakened portion may be provided on the inner tray 9 and connected to the inner tray-side engaging portion 9f. Furthermore, in the above-described embodiment, when engaging the first protrusion 6c and the second protrusion 9e, the tubular portion 6a is provided with a slit 6d to elastically deform the tubular portion 6a, but the shaft portion 9d may be provided with a slit to elastically deform the shaft portion 9d. In the above-described embodiment, the cartridge body 8 is provided with a claw portion 8k and the base body 3 is provided with a hole 3d, but a hole may be provided in the cartridge body 8 and a claw portion may be provided in the base body 3.
