Description

[Technical field]

[0001] The present invention relates to a container for dispensing a stick-shaped cosmetic material. [Background technology]

[0002] Patent Document 1 describes a container for dispensing stick-shaped cosmetic material equipped with a core chuck (stick-shaped cosmetic material holding member) for holding the stick-shaped cosmetic material. In this container, the core chuck is formed by providing multiple slits in a cylindrical core chuck body and dividing the circumferential portion into multiple holding pieces (jaw pieces). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-329176 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the container described in Patent Document 1, the multiple holding pieces have a cantilever shape with only their base ends connected to the inner bottom of the core chuck body. Therefore, in this container, when a stick-shaped cosmetic material is inserted, the tips of the multiple holding pieces spread apart from each other, making it impossible to stably hold the stick-shaped cosmetic material, and there is a risk that the stick-shaped cosmetic material will come off the holding pieces.

[0005] The inventor has proposed a structure for stably holding a stick-shaped cosmetic material by providing a band that connects a portion of a plurality of claw pieces, thereby preventing the tips of the claw pieces from moving apart from each other. In this structure, the band connects a portion of a plurality of claw pieces, so that the shape of the cosmetic material holding portion differs between the portion connected by the band and the portion not connected by the band. Accordingly, the inner circumference of the leading tube through which the stick-shaped cosmetic material holding member advances and retreats is formed into a shape that allows the band to be inserted, corresponding to the circumferential position where the band is provided.

[0006] However, when assembling the container for dispensing stick-shaped cosmetic material by inserting the stick-shaped cosmetic material holding member into the front tube, if the band is inserted into a position where it cannot be inserted, there is a risk that the band will be damaged.

[0007] The present invention has been made in consideration of the above technical problems, and has an object to prevent damage to the band portion when the cosmetic material holding member is inserted into the leading tube. [Means for solving the problem]

[0008] According to one aspect of the present invention, a stick-shaped cosmetic material dispensing container has a cosmetic material holding part that holds an outer circumferential surface of a stick-shaped cosmetic material and a base part from which the cosmetic material holding part stands, and is equipped with a stick-shaped cosmetic material holding member that holds the stick-shaped cosmetic material, a front tube having a through hole through which the stick-shaped cosmetic material can be advanced and retreated, a base tube that is assembled so as to be rotatable relative to the front tube, and a dispensing mechanism that advances and retreats the stick-shaped cosmetic material held by the stick-shaped cosmetic material holding member from a tip opening of the through hole of the front tube by relative rotation between the front tube and the base tube, and the cosmetic material holding part extends along the axial direction of the stick-shaped cosmetic material and supports the stick-shaped cosmetic material. The stick-shaped cosmetic holding member has a plurality of claw pieces that hold the outer peripheral surface of the stick-shaped cosmetic material, a bottom portion that holds the bottom of the stick-shaped cosmetic material, and a band portion formed in part of the circumferential direction to connect at least a pair of the claw pieces in the circumferential direction, and the through hole has a first wall portion along which the outer peripheral surface of the stick-shaped cosmetic material slides in the axial direction, and a second wall portion along which the band portion slides in the axial direction as the stick-shaped cosmetic material holding member moves forward and backward, and has an assembly angle determining mechanism that determines the assembly angle between the claw pieces and the through hole about the central axis so that the band portion is positioned at the second wall portion when the stick-shaped cosmetic material holding member is inserted into the leading tube. Effect of the Invention

[0009] According to the above aspect, since the assembly angle regulating mechanism is provided, when the stick-shaped cosmetic material holder is inserted into the leading tube, the assembly angle between the claw and the through hole about the central axis is regulated so that the belt portion is positioned on the second wall portion. Therefore, the belt portion is prevented from being inserted into a position where it cannot be inserted, and damage to the belt portion can be prevented when the cosmetic material holder is inserted into the leading tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] First Embodiment First, with reference to Figs. 1 to 3, a stick-shaped cosmetic material dispensing container (hereinafter simply referred to as "dispensing container") 1 according to a first embodiment of the present invention will be described.

[0013] Fig. 1 is a cross-sectional view of the dispensing container 1, where (a) shows a state in which the core chuck member 10 is positioned at the most retracted position, (b) is a cross-sectional view along line IB-IB in Fig. 1(a), (c) is a cross-sectional view showing only the leading tube 20 in Fig. 1(b), and (d) is a cross-sectional view showing only the core chuck member 10 in Fig. 1(b). Fig. 2 is a view showing the core chuck member 10, where (a) is a front view, (b) is a side view, and (c) is a cross-sectional view showing an enlarged view of the cosmetic material holding portion 11 in the core chuck member 10. Fig. 3 is an enlarged view of the cosmetic material holding portion 11, where (a) is a front view, (b) is a side view, (c) is a plan view showing a state before a stick-shaped cosmetic material A is inserted, and (d) is a cross-sectional view along line IIID-IIID in Fig. 3(a) showing a state in which a stick-shaped cosmetic material A has been inserted.

[0014] As shown in Fig. 1(a), the dispensing container 1 is a container capable of dispensing a stick-shaped cosmetic material A having a substantially circular cross-sectional shape. The stick-shaped cosmetic material A is a molded core formed into a stick shape and is used, for example, as an eyebrow, eyeliner, lip liner, etc. The outer diameter of the stick-shaped cosmetic material A is formed to be slightly larger than the inner diameter of a cosmetic material holding portion 11 (see Figs. 3(a) and 3(b)) which will be described later.

[0015] The dispensing container 1 comprises a leading tube 20 having a through hole 20a through which the stick-shaped cosmetic material A can advance and retreat, a base tube 30 assembled to the leading tube 20 so as to be rotatable relative to the leading tube 20, a core chuck member 10 as a stick-shaped cosmetic material holding member that holds the stick-shaped cosmetic material A, and a female threaded tube 40 provided in the base tube 30 so as not to be rotatable relative to the base tube 30. Hereinafter, the direction along the central axis of the through hole 20a in the leading tube 20 will be referred to as the "axial direction", the direction around the central axis of the through hole 20a will be referred to as the "circumferential direction", and the radial direction around the central axis of the through hole 20a will be referred to as the "radial direction". In addition, the movement of the stick-shaped cosmetic material A being dispensed from the dispensing container 1 will be referred to as the "forward movement", and the movement of the stick-shaped cosmetic material A being fed back into the dispensing container 1 will be referred to as the "rearward movement".

[0016] The front tube 20 is a tubular member in which a through hole 20a is formed penetrating in the axial direction. The front tube 20 has a knob 23 which is pinched by the user, and an insertion portion 24 which is formed axially continuous with the knob 23 and is inserted into the base tube 30. The cross-sectional shape of the through hole 20a is similar to the cross-sectional shape of the stick-shaped cosmetic material A, and is formed in a substantially circular shape. The knob 23 is formed in a tapered shape in the axial direction so that the outer diameter gradually decreases from the insertion portion 24 side toward the tip.

[0017] On the outer circumferential surface of the fitting portion 24, there are formed an annular fitting protrusion 25 that fits into a fitting recess 32 (described later) formed in the base tube 30, and an O-ring groove 26 in which the O-ring 2 is attached. The O-ring 2 is provided in a compressed state between the front tube 20 and the base tube 30, thereby generating an appropriate resistance when the front tube 20 and the base tube 30 are rotated relative to each other. This improves the operability of the user.

[0018] The through hole 20a extends along the axial direction and has a guide groove 21 that protrudes radially outward to guide the core chuck member 10 along the axial direction, a first wall-like portion 22a against which the outer peripheral surface of the rod-shaped cosmetic material A slides along the axial direction, and a second wall-like portion 22b against which the connecting belt 13 described later slides along the axial direction as the core chuck member 10 moves forward and backward.

[0019] 1(b), the guide groove 21 is configured with a plurality of (four here) grooves in a generally H-shape. The plurality of guide grooves 21 are arranged at irregular intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12.

[0020] The inner peripheral surface of the guide groove 21 is formed in a curved shape so as to form a part of an arc about the central axis. In the guide groove 21, the claw pieces 12 of the core chuck member 10, which will be described later, are positioned, and the engaging ridge portion 16, which will be described later, engages with the claw pieces 12.

[0021] 1(a), the guide groove 21 is formed up to the rear end surface 20c of the front tube 20. The guide groove 21 is formed up to just before the front end opening 20b of the through hole 20a without reaching the front end opening 20b.

[0022] The guide groove 21 has a pair of first guide grooves 21a arranged adjacent to each other in parallel and a pair of second guide grooves 21b arranged adjacent to each other in parallel. The first guide groove 21a and the second guide groove 21b are arranged to face each other across the central axis.

[0023] As shown in FIG. 1(b), a plurality of first wall portions 22a are provided in the circumferential direction. The first wall portions 22a are provided between the first guide groove 21a and the second guide groove 21b that are adjacent in the circumferential direction. A pair of the first wall portions 22a are provided to face each other across the central axis. The pair of first wall portions 22a are provided to sandwich the stick-shaped cosmetic material A in the radial direction. The first wall portions 22a are not limited to a pair of facing portions as long as they are capable of supporting the outer circumferential surface of the stick-shaped cosmetic material A.

[0024] A plurality of second wall portions 22b are provided in the circumferential direction. The second wall portions 22b are provided between a pair of circumferentially adjacent first guide grooves 21a and between a pair of circumferentially adjacent second guide grooves 21b. A pair of second wall portions 22b are provided to face each other across the central axis. The pair of second wall portions 22b face the outer circumferential surface of the connecting belt 13. As long as the second wall portions 22b face the outer circumferential surface of the connecting belt 13, they are not limited to being a pair facing each other.

[0025] As shown in FIG. 1(c), the inner diameter dimension α-α between a pair of opposing first wall portions 22a is smaller than the inner diameter dimension β-β between a pair of opposing second wall portions 22b (α-α<β-β).

[0026] 1(a), the base tube 30 is a member formed in a bottomed cylindrical shape that houses the core chuck member 10 and has an accommodation hole 33 into which the fitting portion 24 of the front tube 20 is fitted and into which the female threaded tube 40 is inserted. The accommodation hole 33 is provided with an annular fitting recess 32 into which the fitting protrusion 25 of the front tube 20 is fitted.

[0027] As shown in Figs. 2(a) and 2(b), the core chuck member 10 includes a cosmetic material holding portion 11 that holds a rod-shaped cosmetic material A, and a base portion 15 on which the cosmetic material holding portion 11 stands.

[0028] A stick-shaped cosmetic material A that is soft, has a small diameter, and has a circular cross-sectional shape is loaded into the cosmetic material holding portion 11. Here, the outside diameter of the stick-shaped cosmetic material A is about φ1.5 to 3.0 [mm].

[0029] The cosmetic material holding portion 11 comprises a plurality of (four in this case) claw pieces 12 which extend along the axial direction of the stick-shaped cosmetic material A and hold the outer peripheral surface of the stick-shaped cosmetic material A, a base portion end surface 15a (see Figure 2(c)) which serves as a bottom portion which holds the bottom of the stick-shaped cosmetic material A, and a connecting band 13 which serves as a band portion formed in part of the circumferential direction and which connects at least one pair of claw pieces 12 in the circumferential direction.

[0030] As shown in FIG. 2(c), the claw pieces 12 are erected in the axial direction from the base end face 15a. The outer peripheral surface of the claw pieces 12 is formed with a smaller diameter than the outer peripheral surface of the engaging ridge portion 16 of the base portion 15. The inner peripheral surface of the claw pieces 12 is formed in a curved shape so as to fit along the outer peripheral surface of the stick-shaped cosmetic material A. Multiple claw pieces 12 (four in this example) are provided so as to sandwich the stick-shaped cosmetic material A. The multiple claw pieces 12 are arranged at uneven intervals in the circumferential direction.

[0031] As shown in Fig. 3(a) to Fig. 3(d), the claw piece 12 has a pair of first claw pieces 12a arranged adjacent to each other in parallel, and a pair of second claw pieces 12b arranged adjacent to each other in parallel. The first claw pieces 12a and the second claw pieces 12b have the same radial thickness and circumferential width. The first claw pieces 12a and the second claw pieces 12b are arranged to face each other across the central axis. The pair of first claw pieces 12a together with the connecting band 13 constitute the holding piece 11a. The pair of second claw pieces 12b together with the connecting band 13 constitute the holding piece 11b.

[0032] The claw pieces 12 are formed to have a radial thickness of about 0.60 mm. Each claw piece 12 has a tapered surface 12d that is inclined so as to move away from the outer circumferential surface of the stick-shaped cosmetic material A toward the tip.

[0033] Tapered surface 12d is provided at a position axially spaced from the tip of claw piece 12. Tapered surface 12d is inclined so that the inner diameter, which is the distance between claw pieces 12 facing each other across the central axis, increases toward the tip. The provision of tapered surface 12d makes it easier to insert stick-shaped cosmetic material A into cosmetic material holding portion 11, and prevents the outer periphery of the rear end of stick-shaped cosmetic material A from being scraped by claw piece 12 when inserting stick-shaped cosmetic material A.

[0034] 3(b), the portion of the hook piece 12 on the tip side of the tapered surface 12d is formed to have a larger diameter than the outer diameter of the stick-shaped cosmetic material A. Therefore, this portion does not come into contact with the stick-shaped cosmetic material A.

[0035] The base end surface 15a is provided at the axial tip of the base portion 15. The bottom surface of the stick-shaped cosmetic material A comes into contact with the base end surface 15a.

[0036] The connecting band 13 is provided so as to connect a pair of adjacent claw pieces 12 arranged in parallel to each other in the circumferential direction. Specifically, one connecting band 13 connects a pair of first claw pieces 12a to each other in the circumferential direction, and the other connecting band 13 connects a pair of second claw pieces 12b to each other in the circumferential direction. In other words, the connecting band 13 connects a pair of claw pieces 12 constituting the holding piece 11a or the holding piece 11b to each other, but does not connect the holding piece 11a and the holding piece 11b. The holding pieces 11a and 11b are formed by the connecting band 13 and a pair of claw pieces 12 adjacent to each other in positions close to each other in the circumferential direction.

[0037] The connecting band 13 extends from the base end surface 15a in the axial direction shorter than the claw pieces 12. A plurality of connecting bands 13 are provided in the circumferential direction. A pair of connecting bands 13 are provided facing each other across the central axis. When three claw pieces 12 are provided in parallel, the connecting band 13 may be formed to connect the three claw pieces 12 in the circumferential direction. In other words, the connecting band 13 connects at least one pair of claw pieces 12 in the circumferential direction.

[0038] In this way, the cosmetic material holding portion 11 of the core chuck member 10 has a connecting band 13 formed on a portion of the circumference that connects at least one pair of claw pieces 12 in the circumferential direction, thereby preventing the multiple claw pieces 12 from spreading apart from each other. Therefore, the stick-shaped cosmetic material A can be stably held, and the stick-shaped cosmetic material A can be prevented from slipping out of the cosmetic material holding portion 11.

[0039] Further, the plurality of claw pieces 12 are arranged at unequal intervals in the circumferential direction, and the plurality of guide grooves 21 are arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12. As a result, when the core chuck member 10 is inserted into the leading tube 20, the assembly angle between the claw pieces 12 and the through hole 20a around the central axis is determined so that the connecting band 13 is located at the second wall-shaped portion 22b. That is, the plurality of claw pieces 12 arranged at unequal intervals in the circumferential direction and the plurality of guide grooves 21 arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12 constitute an assembly angle determination mechanism that determines the assembly angle between the claw pieces 12 and the through hole 20a around the central axis so that the connecting band 13 is located at the second wall-shaped portion 22b when the core chuck member 10 is inserted into the leading tube 20. Therefore, the connecting band 13 is prevented from being inserted into a position where the connecting band 13 cannot be inserted, so that damage to the connecting band 13 can be prevented when the core chuck member 10 is inserted into the leading tube 20.

[0040] As shown in Figures 1(b) to 1(d), the outer diameter dimension θ-θ of the multiple connecting straps 13 is larger than the inner diameter dimension α-α of the multiple first wall portions 22a and smaller than the inner diameter dimension β-β of the multiple second wall portions 22b (α-α<θ-θ<β-β).

[0041] That is, the clearance between the inner peripheral surface (inner diameter dimension α-α) of the first wall portion 22a, into which the position where the connecting band 13 is not provided is inserted, and the outer peripheral surface of the stick-shaped cosmetic material A is set to be smaller than the clearance between the inner peripheral surface (inner diameter dimension β-β) of the second wall portion 22b, into which the connecting band 13 is inserted, and the outer peripheral surface of the stick-shaped cosmetic material A. Moreover, the inner diameter dimension β-β of the opposing second wall portion 22b is set to be larger than the outer diameter dimension θ-θ of the opposing connecting band 13.

[0042] As described above, the multiple claw pieces 12 arranged at uneven intervals in the circumferential direction and the multiple guide grooves 21 arranged at uneven intervals in the circumferential direction to correspond to the positions of the multiple claw pieces 12 constitute an assembly angle determination mechanism, so that when the core chuck member 10 is inserted into the through hole 20a, the position of the core chuck member 10 where the connecting band 13 is not provided is guided to the first wall-shaped portion 22a, and the position where the connecting band 13 is provided is guided to the second wall-shaped portion 22b.

[0043] Therefore, the position where the connecting band 13 is not provided is always guided to the first wall portion 22a, so that the clearance between the inner peripheral surface of the first wall portion 22a and the outer peripheral surface of the stick-shaped cosmetic material A can be minimized. Therefore, even if the stick-shaped cosmetic material A tilts when the core chuck member 10 advances and retreats, the inner peripheral surface of the first wall portion 22a can always support the outer peripheral surface of the stick-shaped cosmetic material A along the axial direction. This prevents the core from breaking due to the tilt of the stick-shaped cosmetic material A, and stabilizes the advancement and retreat of the stick-shaped cosmetic material A. Furthermore, even if a stick-shaped cosmetic material A with a small core diameter and a large core length is loaded and the payout stroke becomes long, the core from the retreat limit to the advance limit of the core chuck member 10 can be prevented from breaking due to the tilt of the stick-shaped cosmetic material A.

[0044] In addition, the position where the connecting belt 13 is provided is always guided by the second wall portion 22b, so that the sliding of the connecting belt 13 can be stabilized. If the connecting belt 13 is inserted into the first wall portion 22a, the inner diameter dimension α-α of the opposing first wall portion 22a is smaller than the outer diameter dimension θ-θ of the opposing connecting belt 13, so that there is a risk that the connecting belt 13 will not slide or will be damaged when the core chuck member 10 advances and retreats. In contrast, the inner diameter dimension β-β of the opposing second wall portion 22b is larger than the outer diameter dimension θ-θ of the opposing connecting belt 13, so that the connecting belt 13 is always guided by the second wall portion 22b, so that the connecting belt 13 can slide stably when the core chuck member 10 advances and retreats.

[0045] 3(c) and 3(d), the inner peripheral surface of the connecting band 13 is formed into a curved shape so as to fit along the outer peripheral surface of the stick-shaped cosmetic material A. In other words, the inner peripheral surface of the connecting band 13 and the inner peripheral surface of the claw piece 12 are formed continuously so as to fit along the outer peripheral surface of the stick-shaped cosmetic material A.

[0046] The connecting strip 13 is formed of a thin film having a radial thickness of about 0.20 to 0.25 mm. That is, the connecting strip 13 has a radial thickness smaller than that of the claw pieces 12. By forming the connecting strip 13 from a thin film, it is possible to increase the degree of adhesion to the outer periphery of the stick-shaped cosmetic material A compared to the case where a thick connecting strip is used, and it is possible to stably hold the stick-shaped cosmetic material A.

[0047] As shown in FIG. 2(c), the connecting strip 13 has a tapered surface 13d on the inner peripheral surface of the tip portion away from the base end surface 15a, which is inclined so as to move away from the outer peripheral surface of the stick-shaped cosmetic material A toward the tip portion.

[0048] Tapered surface 13d is formed with an incline so that the inner diameter, which is the distance between the pair of connecting bands 13, increases toward the tip. The provision of tapered surface 13d makes it easier to insert stick-shaped cosmetic material A into cosmetic material holding portion 11, and prevents the outer periphery of the rear end portion of stick-shaped cosmetic material A from being scraped by connecting bands 13 when inserting stick-shaped cosmetic material A.

[0049] As shown in Figures 2(a) and 2(b), the base portion 15 has an engagement rib portion 16 that circumferentially engages with the guide groove 21, and a male thread portion 17 that is formed continuously from the engagement rib portion 16 in the axial direction.

[0050] The engagement rib portion 16 is formed on the outer periphery of the portion between the base end surface 15a on which the claw piece 12 is erected and the male thread portion 17. The engagement rib portion 16 is formed linearly along the axial direction. The engagement rib portion 16 engages with the guide groove 21 of the front tube 20, thereby restricting the relative rotation in the circumferential direction between the front tube 20 and the core chuck member 10. A groove is formed between adjacent engagement ribs 16 up to the groove end surface 19. The groove end surface 19 determines the forward movement limit of the core chuck member 10 when it abuts against the rear end surface 20c of the second wall portion 22b of the front tube 20.

[0051] The male thread portion 17 is provided in a plurality of positions so as to protrude from the engaging rib portion 16 in the axial direction to the outer periphery of a portion formed to have a smaller diameter than the engaging rib portion 16. The male thread portion 17 is provided at a plurality of positions (two positions in this case) in the circumferential direction and at a plurality of positions in the axial direction. The male thread portion 17 screws into the female thread portion 43 of the female thread tube 40.

[0052] 1(a), the female threaded tube 40 is a tubular member made of resin and formed with a female threaded portion 43 penetrating in the axial direction, with which the male threaded portion 17 of the core chuck member 10 engages. The female threaded tube 40 has a rear end surface 44 that abuts against the step portion 35 of the base tube 30 when inserted into the base tube 30, and a front end surface 42 that abuts against the rear end surface 20c of the front tube 20 when the front tube 20 is assembled to the base tube 30.

[0053] A plurality of axially extending vertical ribs (not shown) are formed at equal intervals in the circumferential direction on the outer circumferential surface of the female thread tube 40. The vertical ribs engage with knurls (not shown) formed on the inner circumferential surface of the base tube 30 and function as a rotation stopper that prevents the female thread tube 40 from rotating relative to the base tube 30.

[0054] When the leading tube 20 and the base tube 30 are rotated relative to each other in a state in which the male thread portion 17 of the core chuck member 10 is screwed into the female thread portion 43 of the female thread tube 40, the core chuck member 10 rotates integrally with the leading tube 20, and the female thread tube 40 rotates integrally with the base tube 30, so that the core chuck member 10 and the base tube 30 rotate relative to each other. As a result, the male thread portion 17 of the core chuck member 10 rotates relative to the female thread portion 43, so that the core chuck member 10 moves relative to the female thread tube 40 in the axial direction. That is, a payout mechanism is formed that advances and retreats the rod-shaped cosmetic material A held by the core chuck member 10 from the tip opening 20b of the through hole 20a of the leading tube 20 by the relative rotation between the leading tube 20 and the base tube 30.

[0055] In this way, in the dispensing container 1, the female threaded tube 40 and the core chuck member 10 form a dispensing mechanism that dispensing the rod-shaped cosmetic material A in the axial direction, and when the front tube 20 and the base tube 30 are rotated relative to each other, the core chuck member 10 moves axially forward and backward within the front tube 20 and the base tube 30, and the rod-shaped cosmetic material A also moves forward and backward in accordance with the movement of the core chuck member 10.

[0056] Specifically, when the user rotates the leading tube 20 and the base tube 30 relative to each other in the forward direction, the core chuck member 10 moves axially toward the tip opening 20b of the leading tube 20, advancing the stick-shaped cosmetic material A. This causes the stick-shaped cosmetic material A to be fed out from the tip opening 20b. On the other hand, when the user rotates the leading tube 20 and the base tube 30 relative to each other in the reverse direction, the core chuck member 10 moves in the reverse direction, retracting the stick-shaped cosmetic material A. This causes the stick-shaped cosmetic material A to be fed back.

[0057] The front end surface 42, in contact with the rear end surface of the engaging rib portion 16, defines the retreat limit of the core chuck member 10.

[0058] <First Modification> Next, a core chuck member 110 and a front tube 120 as a stick-shaped cosmetic material holding member according to a first modified example of the first embodiment of the present invention will be described with reference to Fig. 4. Note that the same components as those in the above-described embodiment are given the same reference numerals, and duplicated descriptions will be omitted as appropriate.

[0059] Figure 4 is a diagram showing a core chuck member 110 relating to a first modified example of the first embodiment of the present invention, where (a) is a front view, (b) is a side view, (c) is a plan view showing the state before a stick-shaped cosmetic material A is inserted, (d) is a cross-sectional view along the IVD-IVD line in Figure 4(a) when a stick-shaped cosmetic material A has been inserted, and (e) is a cross-sectional view of the front tube 120 at the same position as in Figure 1(b).

[0060] The core chuck member 110 according to this first modified example differs from the first embodiment described above in the axial and circumferential positions of the connecting band 113.

[0061] As shown in Figs. 4(a) and 4(b), the core chuck member 110 includes a cosmetic material holding portion 111 that holds a stick-shaped cosmetic material A, and a base portion 15 on which the cosmetic material holding portion 111 stands.

[0062] The cosmetic material holding portion 111 comprises a plurality of (four here) claw pieces 12 which extend along the axial direction of the stick-shaped cosmetic material A and hold the outer peripheral surface of the stick-shaped cosmetic material A, a base portion end surface 15a which serves as a bottom surface portion which holds the bottom of the stick-shaped cosmetic material A, and a connecting band 113 which serves as a band portion formed in part of the circumferential direction and which connects at least one pair of claw pieces 12 in the circumferential direction.

[0063] The claw pieces 12 are erected in the axial direction from the base end surface 15a. The inner peripheral surface of the claw pieces 12 is curved to fit the outer peripheral surface of the stick-shaped cosmetic material A. As shown in Fig. 4(c), multiple claw pieces 12 (four in this example) are provided to sandwich the stick-shaped cosmetic material A. The multiple claw pieces 12 are arranged at uneven intervals in the circumferential direction.

[0064] The claw pieces 12 have a pair of first claw pieces 12a arranged adjacent to each other in parallel, and a pair of second claw pieces 12b arranged adjacent to each other in parallel. In this first modified example, the first claw pieces 12a and the second claw pieces 12b arranged adjacent to each other on the same straight line, rather than a pair of claw pieces 12 arranged adjacent to each other in parallel, form two sets of holding pieces 111a, 111b, which are arranged opposite each other across the central axis, together with a connecting band 113.

[0065] The connecting band 113 is provided so as to connect the first claw piece 12a and the second claw piece 12b, which are provided on the same straight line and adjacent to each other in the circumferential direction, in the circumferential direction. That is, the connecting band 113 connects a pair of claw pieces 12 constituting the holding piece 111a or the holding piece 111b, but does not connect the holding piece 111a and the holding piece 111b. The holding pieces 111a and 111b are formed by the connecting band 113 and a pair of claw pieces 12 adjacent to each other at positions spaced apart in the circumferential direction.

[0066] A plurality of connecting belts 113 are provided in the circumferential direction. A pair of connecting belts 113 are provided facing each other with the central axis therebetween.

[0067] The front tube 120 is a tubular member in which a through hole 120a is formed penetrating in the axial direction. The front tube 120 has a gripping portion 23 which is gripped by the user, and an insertion portion 24 which is formed continuous with the gripping portion 23 in the axial direction and which is inserted into the base tube 30. The cross-sectional shape of the through hole 120a is similar to the cross-sectional shape of the stick-shaped cosmetic material A, and is formed in a substantially circular shape.

[0068] The through hole 120a extends along the axial direction and has a guide groove 21 that protrudes radially outward to guide the core chuck member 110 along the axial direction, a first wall-like portion 122a against which the outer peripheral surface of the rod-shaped cosmetic material A slides along the axial direction, and a second wall-like portion 122b against which the connecting belt 113 described later slides along the axial direction as the core chuck member 110 moves forward and backward.

[0069] 4(e), the guide groove 21 is configured with a plurality of (four here) grooves in a generally H-shape. The plurality of guide grooves 21 are arranged at irregular intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12.

[0070] A plurality of first wall portions 122a are provided in the circumferential direction. The first wall portions 122a are provided between a pair of first guide grooves 21a adjacent to each other in the circumferential direction and between a pair of second guide grooves 21b adjacent to each other in the circumferential direction. A pair of first wall portions 122a are provided to face each other across the central axis. The pair of first wall portions 122a are provided to sandwich the stick-shaped cosmetic material A in the radial direction. The first wall portions 122a are not limited to a pair of facing portions as long as they are capable of supporting the outer circumferential surface of the stick-shaped cosmetic material A.

[0071] A plurality of second wall portions 122b are provided in the circumferential direction. The second wall portions 122b are provided between the first guide groove 21a and the second guide groove 21b that are adjacent in the circumferential direction. A pair of second wall portions 122b are provided to face each other across the central axis. The pair of second wall portions 122b faces the outer circumferential surface of the connecting belt 113. As long as the second wall portions 122b face the outer circumferential surface of the connecting belt 113, they are not limited to being a pair facing each other.

[0072] The plurality of claw pieces 12 are arranged at unequal intervals in the circumferential direction, and the plurality of guide grooves 21 are arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12. As a result, when the core chuck member 110 is inserted into the leading tube 120, the assembly angle between the claw pieces 12 and the through hole 120a around the central axis is determined so that the connecting band 113 is positioned on the second wall-shaped portion 122b. That is, the plurality of claw pieces 12 arranged at unequal intervals in the circumferential direction and the plurality of guide grooves 21 arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12 constitute an assembly angle determination mechanism that determines the assembly angle between the claw pieces 12 and the through hole 120a around the central axis so that the connecting band 113 is positioned on the second wall-shaped portion 122b when the core chuck member 110 is inserted into the leading tube 120. Therefore, since the connecting belt 113 is prevented from being inserted into a position where the connecting belt 113 cannot be inserted, damage to the connecting belt 113 when the core chuck member 110 is inserted into the leading tube 120 can be prevented.

[0073] The inner diameter dimension α-α between the pair of opposing first wall portions 122a is smaller than the inner diameter dimension β-β between the pair of opposing second wall portions 122b (α-α<β-β). Also, the outer diameter dimension θ-θ of the pair of opposing connecting belts 113 is larger than the inner diameter dimension α-α of the pair of opposing first wall portions 122a and smaller than the inner diameter dimension β-β of the multiple second wall portions 122b (α-α<θ-θ<β-β).

[0074] Therefore, as in the first embodiment described above, core breakage due to inclination of the stick-shaped cosmetic material A can be prevented, and the forward and backward movement of the stick-shaped cosmetic material A can be stabilized. In addition, since the connecting belt 113 is always guided by the second wall-shaped portion 122b, the core chuck member 110 can slide stably when moving forward and backward.

[0075] The connecting belt 113 is formed on a portion of the circumference and connects at least one pair of claw pieces 12 in the circumference. The connecting belt 113 is provided at a position spaced from the base end face 15a toward the axial tip end. As a result, a space 114 is formed between the base end face 15a and the connecting belt 113. The provision of the space 114 allows the outer peripheral surface of the stick-shaped cosmetic material A inserted into the cosmetic material holding part 111 to bite into the space 114, thereby strengthening the engagement of the stick-shaped cosmetic material A with the cosmetic material holding part 111. Therefore, even if the stick-shaped cosmetic material A is about to move axially forward due to an impact or the like, the outer periphery of the stick-shaped cosmetic material A gets caught on the rear end surface of the connecting belt 113, preventing the stick-shaped cosmetic material A from coming off.

[0076] The connecting band 113 is provided at a position spaced axially from the tip of the claw piece 12 toward the base end face 15a. As a result, a claw piece elastic portion 12e is formed on the tip side of the connecting band 113 in the claw piece 12. The claw piece elastic portion 12e expands toward the outer periphery when the stick-shaped cosmetic material A is inserted into the cosmetic material holding portion 111, so that the stick-shaped cosmetic material A can be smoothly guided into the cosmetic material holding portion 111.

[0077] The connecting strip 113 has a tapered surface 113d on the inner peripheral surface of the tip portion remote from the base portion end surface 15a, which is inclined so as to move away from the outer peripheral surface of the stick-shaped cosmetic material A towards the tip portion.

[0078] Tapered surface 113d is formed with an incline so that the inner diameter, which is the distance between the pair of connecting bands 113, increases toward the tip. The provision of tapered surface 113d makes it easier to insert stick-shaped cosmetic material A into cosmetic material holding portion 111, and prevents the outer periphery of the rear end portion of stick-shaped cosmetic material A from being scraped by connecting bands 113 when inserting stick-shaped cosmetic material A.

[0079] In this way, the cosmetic material holding portion 111 of the core chuck member 110 has connecting bands 113 that connect the multiple claw pieces 12 in the circumferential direction at a position spaced from the base portion end face 15a that holds the bottom of the stick-shaped cosmetic material A, thereby preventing the multiple claw pieces 12 from spreading apart from each other. Therefore, the holding force of the claw pieces 12 to hold the stick-shaped cosmetic material A is reinforced by the connecting bands 113, so that the stick-shaped cosmetic material A can be stably held.

[0080] The inner peripheral surface of the connecting strip 113 is curved to fit the outer peripheral surface of the stick-shaped cosmetic material A. That is, the inner peripheral surface of the connecting strip 113 and the inner peripheral surface of the claw piece 12 are continuously formed to fit the outer peripheral surface of the stick-shaped cosmetic material A. The connecting strip 113 is formed of a thin film having a radial thickness of about 0.20 to 0.25 mm, similar to the connecting strip 13 of the first embodiment. That is, the connecting strip 113 has a smaller radial thickness than the claw piece 12. By forming the connecting strip 113 from a thin film, it is possible to increase the degree of adhesion to the outer peripheral surface of the stick-shaped cosmetic material A compared to the case of using a thick connecting strip.

[0081] Furthermore, simply by changing the circumferential position of the connecting band 113 without changing the position of the claw pieces 12 from the core chuck member 10 according to the first embodiment, the area in which the inner peripheral surface of the connecting band 113 holds the outer peripheral surface of the stick-shaped cosmetic material A becomes larger. Therefore, the holding force for holding the stick-shaped cosmetic material A is strengthened, and the effect of preventing the stick-shaped cosmetic material A from slipping out can be improved.

[0082] In this way, by arranging multiple claw pieces 12 at unequal intervals in the circumferential direction and setting the circumferential length of the claw pieces 12 at positions where they are connected by the connecting bands 13, 113 to be different from the circumferential length at positions where they are not connected, it is possible to reduce or increase the area over which the connecting bands 13, 113 hold the outer circumferential surface of the stick-shaped cosmetic material A, simply by changing the circumferential position of the connecting bands 13, 113. Therefore, the holding force can be adjusted to suit the core diameter and material of the stick-shaped cosmetic material A, with just a simple design change.

[0083] <Second Modification> Next, a core chuck member 210 as a stick-shaped cosmetic material holding member according to a second modified example of the first embodiment of the present invention will be described with reference to Fig. 5. Note that the same components as those in the above-mentioned embodiment are given the same reference numerals, and duplicated descriptions will be omitted as appropriate.

[0084] Figure 5 is a diagram showing a core chuck member 210 relating to a second modified example of the first embodiment of the present invention, (a) is a front view, (b) is a side view, (c) is a cross-sectional view along line VC-VC in Figure 5(b), and (d) is a cross-sectional view along line VD-VD in Figure 5(b).

[0085] The core chuck member 210 according to the second modified example differs from the first modified example described above in that the connecting band 213 has a tongue portion 213b.

[0086] As shown in Figs. 5(a) and 5(b), the core chuck member 210 includes a cosmetic material holding portion 211 that holds a stick-shaped cosmetic material B, and a base portion 15 on which the cosmetic material holding portion 211 stands.

[0087] A stick-shaped cosmetic material B, which is harder than the stick-shaped cosmetic material A, is loaded into the cosmetic material holding portion 211. The stick-shaped cosmetic material B is formed to have the same outer diameter and length as the stick-shaped cosmetic material A.

[0088] The cosmetic material holding part 211 comprises a plurality of (four in this example) claw pieces 12 that extend along the axial direction of the stick-shaped cosmetic material B and hold the outer peripheral surface of the stick-shaped cosmetic material B, a base end face 15a as a bottom surface part that holds the bottom of the stick-shaped cosmetic material B, and a connecting band 213 as a band part that circumferentially connects at least a pair of claw pieces 12 at a position axially spaced from the base end face 15a. The connecting band 213 has a tongue part 213b that extends axially from the connecting band 213 and has a curved inner peripheral surface that fits along the outer peripheral surface of the stick-shaped cosmetic material B.

[0089] The tongue portion 213b is provided in a space 214 formed between the base portion end face 15a and the connecting band 213. The tongue portion 213b is extended in the axial direction from the connecting band 213 toward the base portion end face 15a, and is formed to a length up to just before the base portion end face 15a. In other words, the tongue portion 213b does not reach the base portion end face 15a, and a space 214 is secured between the tongue portion 213b and the base portion end face 15a. The free end portion of the tongue portion 213b on the side closer to the base portion end face 15a is formed in a substantially semicircular arc shape (curved shape) along the circumferential direction.

[0090] In this way, the cosmetic material holding portion 211 of the core chuck member 210 has the tongue portion 213b that extends axially from the connecting band 213 and has a curved inner peripheral surface that fits along the outer peripheral surface of the stick-shaped cosmetic material B, so that it can hold the outer peripheral surface of the stick-shaped cosmetic material B long along the axial direction. Therefore, the holding force of the claw piece 12 to hold the stick-shaped cosmetic material B is reinforced by the tongue portion 213b, so that the stick-shaped cosmetic material B can be stably held.

[0091] Due to the provision of tongue portion 213b, connecting band 213 is provided at an axial position closer to the tip than connecting band 113 of the first modified example. Therefore, the portion from base portion end face 15a to the tip of connecting band 213 forms cosmetic material holding portion 212e that holds stick-shaped cosmetic material B. Because stick-shaped cosmetic material B is harder than stick-shaped cosmetic material A, stick-shaped cosmetic material B can be inserted relatively smoothly into cosmetic material holding portion 211 without using the elasticity of the claw piece elastic portion.

[0092] The inner peripheral surface of the connecting strip 213 is curved to fit the outer peripheral surface of the stick-shaped cosmetic material B. That is, the inner peripheral surface of the connecting strip 213 and the inner peripheral surface of the claw piece 12 are continuously formed to fit the outer peripheral surface of the stick-shaped cosmetic material B. The connecting strip 213 is formed of a thin film having a radial thickness of about 0.20 to 0.25 mm. On the other hand, the tongue portion 213b is formed of an extremely thin film having a radial thickness of about 0.10 mm. That is, the tongue portion 213b is formed to have a smaller radial thickness than the connecting strip 213. This increases the degree of adhesion of the tongue portion 213b to the outer peripheral surface of the stick-shaped cosmetic material B.

[0093] In addition, by forming the cosmetic material holding portion 212e, the expansion of the tip side of the claw piece 12 is suppressed, and the stick-shaped cosmetic material B can be held longer in the axial direction, thereby further reinforcing the holding force for holding the stick-shaped cosmetic material B.

[0094] Moreover, by simply modifying the design to provide a tongue portion 213b on the connecting band 213, the holding force can be adjusted to suit the core diameter and material of the stick-shaped cosmetic material B. Furthermore, since the parts other than the core chuck member 210 can be those of the first modified example, the manufacturing costs can be reduced.

[0095] <Third Modification> Next, a core chuck member 710 as a stick-shaped cosmetic material holding member according to a third modified example of the first embodiment of the present invention will be described with reference to Fig. 6. Note that the same components as those in the above-mentioned embodiment are given the same reference numerals, and duplicated descriptions will be omitted as appropriate.

[0096] Figure 6 is a diagram showing a core chuck member 710 relating to a third modified example of the first embodiment of the present invention, where (a) is a front view, (b) is a side view, (c) is a plan view showing the state before a stick-shaped cosmetic material A is inserted, (d) is a cross-sectional view along the VID-VID line in Figure 6(b), and (e) is a cross-sectional view of the front tube 720 at the same position as in Figure 1(b).

[0097] A core chuck member 710 according to the third modified example differs from the above-described first embodiment in that the core chuck member 710 holds a stick-shaped cosmetic material A by a single holding piece 11a and a single second claw piece 712b.

[0098] As shown in FIGS. 6(a) and (b), the core chuck member 710 includes a cosmetic material holding portion 711 that holds a stick-shaped cosmetic material A, and a base portion 715 on which the cosmetic material holding portion 711 stands.

[0099] The cosmetic material holding portion 711 comprises a plurality of (three in this case) claw pieces 12 which extend along the axial direction of the stick-shaped cosmetic material A and hold the outer peripheral surface of the stick-shaped cosmetic material A, a base end surface 15a which serves as a bottom surface portion which holds the bottom of the stick-shaped cosmetic material A, and a connecting band 13 which serves as a band portion formed in part of the circumferential direction and which connects a pair of claw pieces 12 in the circumferential direction.

[0100] The claw pieces 12 are erected in the axial direction from the base end surface 15a. The inner peripheral surface of the claw pieces 12 is curved to fit the outer peripheral surface of the stick-shaped cosmetic material A. As shown in Fig. 6(c), multiple claw pieces 12 (three in this example) are provided to sandwich the stick-shaped cosmetic material A. The multiple claw pieces 12 are arranged at uneven intervals in the circumferential direction.

[0101] The claw piece 12 has a pair of first claw pieces 12a arranged adjacent to each other in parallel, and a single second claw piece 712b. The first claw piece 12a and the second claw piece 712b have the same radial thickness and circumferential width. The pair of first claw pieces 12a and the pair of second claw pieces 712b are arranged to face each other across the central axis. The pair of first claw pieces 12a, together with the connecting band 13, constitute the holding piece 11a.

[0102] The second claw piece 712b is formed to have a radial thickness of about 0.60 mm, similar to the first claw piece 12a. The second claw piece 12b also has a tapered surface 12d that is inclined toward the tip so as to move away from the outer circumferential surface of the stick-shaped cosmetic material A.

[0103] The connecting band 13 is provided so as to connect a pair of adjacent first claw pieces 12a provided in parallel to each other in the circumferential direction. That is, the connecting band 13 connects a pair of claw pieces 12 constituting the holding piece 11a to each other, but does not connect the holding piece 11a to the second claw piece 712b. The holding piece 11a is formed by the connecting band 13 and a pair of adjacent claw pieces 12 located close to each other in the circumferential direction.

[0104] 6(e), the front tube 720 is a tubular member in which a through hole 720a is formed penetrating in the axial direction. The front tube 720 has a gripping portion 23 which is gripped by the user, and an insertion portion 24 which is formed continuous with the gripping portion 23 in the axial direction and which is inserted into the base tube 30. The cross-sectional shape of the through hole 720a is similar to the cross-sectional shape of the stick-shaped cosmetic material A, and is formed in a substantially circular shape.

[0105] The through hole 720a extends along the axial direction and has a guide groove 21 that protrudes radially outward to guide the core chuck member 710 along the axial direction, a first wall-like portion 722a against which the outer peripheral surface of the rod-shaped cosmetic material A slides along the axial direction, and a second wall-like portion 22b against which the connecting belt 13 described later slides along the axial direction as the core chuck member 710 moves forward and backward.

[0106] The guide groove 21 is configured by a plurality of grooves (three in this example) in a substantially Y-shape. The plurality of guide grooves 21 are disposed at uneven intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12.

[0107] The guide groove 21 has a pair of first guide grooves 21a arranged adjacent to each other in parallel, and a single second guide groove 721a. The pair of first guide grooves 21a and second guide groove 721b are arranged to face each other across the central axis.

[0108] A plurality of first wall portions 722a are provided in the circumferential direction. The first wall portions 722a are provided between the first guide groove 21a and the second guide groove 721b that are adjacent in the circumferential direction. A pair of first wall portions 722a are provided symmetrically about a plane including the central axis. The pair of first wall portions 722a hold the outer peripheral surface so as to sandwich the stick-shaped cosmetic material A. The first wall portions 722a are not limited to an opposing pair as long as they are capable of supporting the outer peripheral surface of the stick-shaped cosmetic material A.

[0109] The second wall portion 22b is provided at one location in the circumferential direction. The second wall portion 22b is provided between a pair of guide grooves 21 adjacent to each other in the circumferential direction. The second wall portion 22b faces the outer peripheral surface of the connecting belt 13. As long as the second wall portion 22b faces the outer peripheral surface of the connecting belt 13, it is not limited to being provided at one location in the circumferential direction.

[0110] The plurality of claw pieces 12 are arranged at unequal intervals in the circumferential direction, and the plurality of guide grooves 21 are arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12. As a result, when the core chuck member 710 is inserted into the leading tube 720, the assembly angle between the claw pieces 12 and the through hole 720a around the central axis is determined so that the connecting band 13 is positioned on the second wall-shaped portion 22b. That is, the plurality of claw pieces 12 arranged at unequal intervals in the circumferential direction and the plurality of guide grooves 21 arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 12 constitute an assembly angle determination mechanism that determines the assembly angle between the claw pieces 12 and the through hole 720a around the central axis so that the connecting band 13 is positioned on the second wall-shaped portion 22b when the core chuck member 710 is inserted into the leading tube 720. Therefore, since the connecting belt 13 is prevented from being inserted into a position where the connecting belt 13 cannot be inserted, damage to the connecting belt 13 when the core chuck member 710 is inserted into the leading tube 720 can be prevented.

[0111] Furthermore, because a single second claw piece 712b is provided facing each other across the central axis of the pair of first claw pieces 12a, the circumferential width of the first wall-shaped portion 722a provided between the first guide groove 21a and the second guide groove 721b, which are arranged at unequal intervals in the circumferential direction to correspond to the positions of the multiple claw pieces 12, increases. This therefore increases the width at which the clearance between the inner peripheral surface of the first wall-shaped portion 722a and the outer peripheral surface of the stick-shaped cosmetic material A can be minimized, further improving the effect of preventing core breakage due to the inclination of the stick-shaped cosmetic material A and stabilizing the advancement and retreat of the stick-shaped cosmetic material A.

[0112] According to the above-described first embodiment, the following effects are achieved.

[0113] The dispensing container 1 has a cosmetic material holding portion 11, 111, 211, 711 that holds the outer circumferential surface of the stick-shaped cosmetic materials A and B, and a base portion 15 on which the cosmetic material holding portion 11, 111, 211, 711 is erected, a core chuck member 10, 110, 210, 710 that holds the stick-shaped cosmetic materials A and B, a leading tube 20, 120, 720 having through holes 20a, 120a, 720a through which the stick-shaped cosmetic materials A and B can advance and retreat, and a base tube 30 that is assembled to the leading tube 20, 120, 720 so as to be rotatable relative to the leading tube 20, 120, 720. and a payout mechanism for advancing and retracting the stick-shaped cosmetic materials A and B held by the core chuck member 10, 110, 210, 710 from the tip opening 20b of the through hole 20a, 120a, 720a of the front tube 20, 120, 720 by relative rotation between the front tube 20, 120, 720 and the base tube 30. The cosmetic material holding portion 11, 111, 211, 711 includes a plurality of claw pieces 12 that extend along the axial direction of the stick-shaped cosmetic materials A and B and hold the outer peripheral surfaces of the stick-shaped cosmetic materials A and B, and a bottom part for holding the bottom of the stick-shaped cosmetic materials A and B. and a connecting band 13, 113, 213 formed in a portion of the circumferential direction and connecting at least one pair of claw pieces 12 in the circumferential direction. The through hole 20a, 120a, 720a has a first wall-shaped portion 22a, 122a, 722a along which the outer circumferential surface of the stick-shaped cosmetic material A, B slides in the axial direction, and a second wall-shaped portion 22b, 122b along which the connecting band 13, 113, 213 slides in the axial direction as the core chuck member 10, 110, 210, 710 advances and retreats. and has an assembly angle determination mechanism (plurality of claw pieces 12 arranged at uneven intervals in the circumferential direction and a plurality of guide grooves 21 arranged at uneven intervals in the circumferential direction to correspond to the positions of the plurality of claw pieces 12) that determines the assembly angle about the central axis between the claw piece 12 and the through hole 20a, 120a, 720a when the core chuck member 10, 110, 210, 710 is inserted into the leading tube 20, 120, 720 so that the connecting band 13, 113, 213 is positioned on the second wall-shaped portion 22b, 122b.

[0114] According to the above embodiment, since the assembly angle regulation mechanism is provided, when the core chuck member 10, 110, 210, 710 is inserted into the leading tube 20, 120, 720, the assembly angle between the claw piece 12 and the through hole 20a, 120a, 720a around the central axis is regulated so that the connecting belt 13, 113, 213 is positioned at the second wall-shaped portion 22b, 122b. Therefore, the connecting belt 13, 113, 213 is prevented from being inserted into a position where the connecting belt 13, 113, 213 cannot be inserted, so that damage to the connecting belt 13, 113, 213 can be prevented when the core chuck member 10, 110, 210, 710 is inserted into the leading tube 20, 120, 720.

[0115] Furthermore, the cosmetic material holding portion 11,111,211,711 of the core chuck member 10,110,210,710 has a connecting band 13,113,213 formed in a portion of the circumferential direction and connecting at least one pair of claw pieces 12 in the circumferential direction, thereby preventing the multiple claw pieces 12 from spreading apart from each other. Therefore, the stick-shaped cosmetic materials A and B can be stably held, and the stick-shaped cosmetic materials A and B can be prevented from slipping out of the cosmetic material holding portion 11,111,211,711.

[0116] The inner peripheral surfaces of the connecting bands 13, 113, 213 and the inner peripheral surface of the claw piece 12 are formed continuously so as to fit along the outer peripheral surfaces of the stick-shaped cosmetic materials A and B.

[0117] Further, the connecting bands 13, 113, 213 are formed of a thin film having a smaller radial thickness than the claw pieces 12.

[0118] According to these configurations, by forming the connecting bands 13, 113, 213 from a thin film, it is possible to increase the degree of adhesion to the outer periphery of the stick-shaped cosmetic materials A, B compared to when a thicker connecting band is used, and to stably hold the stick-shaped cosmetic materials A, B. Also, since the claw pieces 12 protrude radially outward beyond the connecting bands 13, 113, 213, it is possible for the claw pieces 12 to be positioned within the guide grooves 21 of the front tubes 20, 120, 720.

[0119] In addition, the connecting bands 13, 113, 213 are provided in multiple positions in the circumferential direction, the first wall-shaped portions 22a, 122a, 722a are provided in multiple positions in the circumferential direction, and the second wall-shaped portions 22b, 122b are provided in multiple positions in the circumferential direction, and the outer diameter dimension of the multiple connecting bands 13, 113, 213 is larger than the inner diameter dimension of the multiple first wall-shaped portions 22a, 122a, 722a and smaller than the inner diameter dimension of the multiple second wall-shaped portions 22b, 122b.

[0120] With this configuration, the clearance between the inner surface of the first wall-shaped portion 22a, 122a, 722a and the outer surface of the stick-shaped cosmetic materials A, B can be minimized, thereby preventing core breakage due to the inclination of the stick-shaped cosmetic materials A, B and stabilizing the advancement and retreat of the stick-shaped cosmetic materials A, B. In addition, the connecting belt 13, 113, 213 is always guided by the second wall-shaped portion 22b, 122b, allowing the core chuck member 10, 110, 210, 710 to slide stably when advancing and retreating.

[0121] The connecting strips 113, 213 are provided at positions spaced apart from the base end surface 15a to form spaces 114, 214 between the connecting strips 113, 213 and the base end surface 15a.

[0122] According to this configuration, a space 114, 214 is formed between the base portion end surface 15a and the connecting band 113, 213. By providing the space 114, 214, the outer peripheral surface of the stick-shaped cosmetic material A inserted into the cosmetic material holding portion 111, 211 bites into the space 114, 214, thereby strengthening the engagement of the stick-shaped cosmetic materials A, B with the cosmetic material holding portion 111, 211. Therefore, even if the stick-shaped cosmetic materials A, B are about to move axially forward due to an impact or the like, the outer peripheral surfaces of the stick-shaped cosmetic materials A, B are caught on the rear end surface of the connecting band 113, 213, preventing the stick-shaped cosmetic materials A, B from falling out.

[0123] The connecting strips 13, 113 also have tapered surfaces 13d, 113d on the inner peripheral surface of the tip portion away from the base end surface 15a, which are inclined so as to move away from the outer peripheral surface of the stick-shaped cosmetic material A toward the tip portion.

[0124] According to this configuration, the provision of tapered surfaces 13d, 113d makes it easier to insert the stick-shaped cosmetic material A into the cosmetic material holding portion 11, 111, and prevents the outer periphery of the rear end portion of the stick-shaped cosmetic material A from being scraped by the connecting band 13, 113 when inserting the stick-shaped cosmetic material A.

[0125] <Second embodiment> Next, a stick-shaped cosmetic material dispensing container (hereinafter simply referred to as a "dispensing container") 301 according to a second embodiment of the present invention will be described with reference to Fig. 7 to Fig. 9. Note that the same components as those in the above-mentioned embodiment or each modified example are given the same reference numerals, and duplicated explanations will be omitted as appropriate.

[0126] Fig. 7 is a cross-sectional view of a dispensing container 301 according to a second embodiment of the present invention, where (a) shows a state in which a core chuck member 310 serving as a stick-shaped cosmetic material holding member is positioned at the retracted limit, (b) is a cross-sectional view taken along line VIIB-VIIB in Fig. 7(a), (c) is a cross-sectional view showing only the front tube 320 in Fig. 7(b), and (d) is a cross-sectional view showing only the core chuck member 310 in Fig. 7(b). Fig. 8 is a view showing the core chuck member 310, where (a) is a front view, (b) is a side view, and (c) is an enlarged cross-sectional view showing the cosmetic material holding portion 311 in the core chuck member 310. Figure 9 is an enlarged view of the cosmetic material holding portion 311, where (a) is a front view, (b) is a plan view showing the state before the stick-shaped cosmetic material A is inserted, and (c) is a cross-sectional view along line IXC-IXC in Figure 9(a) showing the state after the stick-shaped cosmetic material A has been inserted.

[0127] As shown in FIG. 7(a), the dispensing container 301 comprises a leading tube 320 having a through hole 320a through which the stick-shaped cosmetic material A can advance and retreat, a base tube 30 assembled to the leading tube 320 so as to be rotatable relative to the leading tube 320, a core chuck member 310 which holds the stick-shaped cosmetic material A, and a female threaded tube 40 which is arranged within the base tube 30 so as not to be rotatable relative to the base tube 30.

[0128] In the second embodiment, the position where the rear end face of the core chuck member 310 abuts against the bottom face of the base tube 30 is defined as the retraction limit of the core chuck member 310.

[0129] The front tube 320 is a tubular member in which a through hole 320a is formed penetrating in the axial direction. The front tube 320 has a gripping portion 23 which is gripped by the user, and an insertion portion 24 which is formed continuous with the gripping portion 23 in the axial direction and which is inserted into the base tube 30. The cross-sectional shape of the through hole 320a is similar to the cross-sectional shape of the stick-shaped cosmetic material A, and is formed in a substantially circular shape.

[0130] The through hole 320a extends along the axial direction and has a guide groove 321 that protrudes radially outward to guide the core chuck member 310 along the axial direction, a first wall-like portion 322a against which the outer peripheral surface of the rod-shaped cosmetic material A slides along the axial direction, and a second wall-like portion 322b against which the connecting belt 313 described later slides along the axial direction as the core chuck member 310 moves forward and backward.

[0131] 7(b), the guide grooves 321 are linear grooves provided at intervals in the circumferential direction. A claw piece 312 (described later) of the core chuck member 310 is positioned in the guide groove 321, and an engaging ridge portion 16 (described later) is engaged therewith. A first wall portion 322a or a second wall portion 322b is formed between adjacent guide grooves 321.

[0132] 7(a), the guide groove 321 is formed up to the rear end surface 20c of the front tube 320. The guide groove 321 is formed up to just before the front end opening 20b of the through hole 320a without reaching the front end opening 20b.

[0133] The guide groove 321 has three first guide grooves 321a arranged adjacent to each other at 90° intervals in the circumferential direction, and a single second guide groove 321b arranged at 90° intervals in the circumferential direction between a pair of first guide grooves 321a. The first guide groove 321a and the second guide groove 321b are arranged to be lined up in sequence at 90° intervals in the circumferential direction.

[0134] The radial depth of second guide groove 321b is smaller than the radial depth of first guide groove 321a, and the circumferential width of second guide groove 321b is smaller than the circumferential width of first guide groove 321a.

[0135] As shown in Fig. 7(c), a plurality of first wall portions 322a are provided in the circumferential direction. The first wall portions 322a are provided between a pair of circumferentially adjacent first guide grooves 321a and between the first guide groove 321a and the second guide groove 321b adjacent in the circumferential direction. The first wall portions 322a are provided in pairs facing each other across the central axis. The pair of first wall portions 322a are provided to sandwich the stick-shaped cosmetic material A in the radial direction. The first wall portions 322a are not limited to a pair facing each other as long as they are capable of supporting the outer circumferential surface of the stick-shaped cosmetic material A.

[0136] A plurality of second wall portions 322b are provided in the circumferential direction. The second wall portions 322b are provided between a pair of circumferentially adjacent first guide grooves 321a and between the circumferentially adjacent first guide groove 321a and second guide groove 321b. A pair of second wall portions 322b are provided facing each other across the central axis. The pair of second wall portions 322b are provided to sandwich the stick-shaped cosmetic material A in the radial direction. The second wall portions 322b are not limited to a pair facing each other as long as they are capable of supporting the outer circumferential surface of the stick-shaped cosmetic material A.

[0137] An inner diameter dimension α2-α2 between a pair of opposing first wall portions 322a is smaller than an inner diameter dimension β2-β2 between a pair of opposing second wall portions 322b (α2-α2<β2-β2).

[0138] As shown in Figs. 8(a) and 8(b), the core chuck member 310 includes a cosmetic material holding portion 311 that holds a stick-shaped cosmetic material A, and a base portion 15 on which the cosmetic material holding portion 311 stands.

[0139] As shown in Figure 9(b), the cosmetic material holding portion 311 comprises multiple (here, four) claw pieces 312 that extend along the axial direction of the stick-shaped cosmetic material A and hold the outer peripheral surface of the stick-shaped cosmetic material A, a base portion end surface 15a (see Figure 9(a)) as a bottom surface portion that holds the bottom of the stick-shaped cosmetic material A, and a connecting band 313 as a band portion that is formed in a portion of the circumferential direction and connects at least a pair of claw pieces 312 in the circumferential direction at a position axially away from the base portion end surface 15a.

[0140] As shown in Fig. 9(a), the claw pieces 312 are erected in the axial direction from the base end face 15a. The outer peripheral surface of the claw pieces 312 is formed with a smaller diameter than the outer peripheral surface of the engaging rib portion 16 of the base portion 15. The inner peripheral surface of the claw pieces 312 is formed in a curved shape so as to fit along the outer peripheral surface of the stick-shaped cosmetic material A. Four claw pieces 312 are provided so as to sandwich the outer periphery of the stick-shaped cosmetic material A in a cross shape.

[0141] The claw pieces 312 have three first claw pieces 312a arranged adjacent to each other at 90° intervals in the circumferential direction, and a single second claw piece 312b arranged between a pair of first claw pieces 312a at 90° intervals in the circumferential direction. The pair of first claw pieces 312a adjacent to each other in the circumferential direction constitute a holding piece 311a together with the connecting band 313. The remaining one first claw piece 312a and the second claw piece 312b constitute a holding piece 311b together with the connecting band 313.

[0142] The radial thickness of the second claw piece 312b is smaller than the radial thickness of the first claw piece 312a, and the circumferential width of the second claw piece 312b is smaller than the circumferential width of the first claw piece 312a.

[0143] Each claw piece 312 has a tapered surface 312d that slopes away from the outer peripheral surface of the stick-shaped cosmetic material A toward the tip, and an inner peripheral convex portion 312c that protrudes toward the inner circumference and serves as an engagement portion that engages with the stick-shaped cosmetic material A.

[0144] Tapered surface 312d is formed with an incline so that the inner diameter, which is the distance between a pair of opposing claw pieces 312, increases toward the tip. The provision of tapered surface 312d makes it easier to insert stick-shaped cosmetic material A into cosmetic material holding portion 311, and prevents the outer periphery of the rear end portion of stick-shaped cosmetic material A from being scraped by claw pieces 312 when inserting stick-shaped cosmetic material A.

[0145] The inner peripheral protrusion 312c engages the stick-shaped cosmetic material A when the stick-shaped cosmetic material A is loaded in the cosmetic material holding portion 311. Instead of the inner peripheral protrusion 312c, for example, a knurled projection may be formed on the inner circumference of the claw piece 312.

[0146] The connecting band 313 is provided so as to connect a pair of circumferentially adjacent claw pieces 312 to each other in the circumferential direction. Specifically, one connecting band 313 connects a pair of adjacent first claw pieces 312a to each other in the circumferential direction, and the other connecting band 313 connects adjacent first claw piece 312a and second claw piece 312b to each other in the circumferential direction. In other words, the connecting band 313 connects a pair of claw pieces 312 constituting the holding piece 311a or the holding piece 311b to each other, but does not connect the holding piece 311a and the holding piece 311b. The holding pieces 311a and 311b are formed by the pair of claw pieces 312 adjacent to each other in the circumferential direction and the connecting band 313.

[0147] As shown in Fig. 9(a), the connecting belt 313 is provided at a position spaced from the base end surface 15a in the axial direction. As a result, a space 314 is formed between the base end surface 15a and the connecting belt 313. The provision of the space 314 allows the outer circumferential surface of the stick-shaped cosmetic material A inserted into the cosmetic material holding part 311 to bite into the space 314, thereby strengthening the engagement of the stick-shaped cosmetic material A with the cosmetic material holding part 311. Therefore, even if the stick-shaped cosmetic material A is about to move axially forward due to an impact or the like, the outer periphery of the stick-shaped cosmetic material A gets caught on the rear end surface of the connecting belt 313, preventing the stick-shaped cosmetic material A from coming off.

[0148] The radial thickness of the second claw piece 312b is smaller than the radial thickness of the first claw piece 312a, and the circumferential width of the second claw piece 312b is smaller than the circumferential width of the first claw piece 312a. The radial depth of the second guide groove 321b is smaller than the radial depth of the first guide groove 321a, and the circumferential width of the second guide groove 321b is smaller than the circumferential width of the first guide groove 321a. As a result, when the core chuck member 310 is inserted into the leading tube 320, the assembly angle of the claw piece 312 and the through hole 320a about the central axis is determined so that the connecting band 313 is positioned at the second wall-shaped portion 322b.

[0149] That is, a configuration in which the radial thickness of at least one second claw piece 312b among the multiple claw pieces 312 is formed smaller than the radial thickness of the other first claw pieces 312a, and the radial depth of at least one second guide groove 321b among the multiple guide grooves 321 is formed smaller than the radial depth of the first guide groove 321a, and a configuration in which the circumferential width of at least one second claw piece 312b among the multiple guide grooves 321 is formed smaller than the circumferential width of the other first claw pieces 312a, and the circumferential width of at least one second guide groove 321b among the multiple guide grooves 321 is formed smaller than the circumferential width of the other first guide grooves 321a, constitute an assembly angle determining mechanism that determines the assembly angle between the claw piece 312 and the through hole 320a about the central axis when the core chuck member 310 is inserted into the front tube 320, so that the connecting band 313 is positioned at the second wall-shaped portion 322b. Therefore, since the connecting belt 313 is prevented from being inserted into a position where the connecting belt 313 cannot be inserted, damage to the connecting belt 313 when the core chuck member 310 is inserted into the leading tube 320 can be prevented.

[0150] In addition, the assembly angle regulating mechanism may be configured using only one of the following configurations: a configuration in which the radial thickness of at least one second claw piece 312b among the multiple claw pieces 312 is formed smaller than the radial thickness of the other first claw pieces 312a, and the radial depth of at least one second guide groove 321b among the multiple guide grooves 321 is formed smaller than the radial depth of the other first guide grooves 321a; and a configuration in which the circumferential width of at least one second claw piece 312b among the multiple claw pieces 312 is formed smaller than the circumferential width of the other first claw pieces 312a, and the circumferential width of at least one second guide groove 321b among the multiple guide grooves 321 is formed smaller than the circumferential width of the other first guide grooves 321a.

[0151] As shown in Figures 7(c) and 7(d), the outer diameter dimension θ2-θ2 of the multiple connecting straps 313 is larger than the inner diameter dimension α2-α2 of the multiple first wall-shaped portions 322a and smaller than the inner diameter dimension β2-β2 of the multiple second wall-shaped portions 322b (α2-α2<θ2-θ2<β2-β2).

[0152] That is, the clearance between the inner peripheral surface (inner diameter dimension α2-α2) of the first wall portion 322a, into which the position where the connecting band 313 is not provided is inserted, and the outer peripheral surface of the stick-shaped cosmetic material A is set to be smaller than the clearance between the inner peripheral surface (inner diameter dimension β2-β2) of the second wall portion 322b, into which the connecting band 313 is inserted, and the outer peripheral surface of the stick-shaped cosmetic material A. Moreover, the inner diameter dimension β2-β2 of the opposing second wall portion 322b is set to be larger than the outer diameter dimension θ2-θ2 of the opposing connecting band 313.

[0153] Therefore, as in the first embodiment described above, by minimizing the clearance between the inner surface of the first wall-shaped portion 322a and the outer surface of the stick-shaped cosmetic material A, core breakage due to inclination of the stick-shaped cosmetic material A can be prevented and the forward and backward movement of the stick-shaped cosmetic material A can be stabilized, and since the connecting belt 313 is always guided by the second wall-shaped portion 322b, the core chuck member 310 can slide stably when moving forward and backward.

[0154] 9(a), the connecting band 313 is provided at a position axially spaced from the tip of the claw piece 312 toward the base end face 15a. This forms a claw piece elastic portion 312e on the tip side of the claw piece 312 relative to the connecting band 313. The claw piece elastic portion 312e expands toward the outer periphery when the stick-shaped cosmetic material A is inserted into the cosmetic material holding portion 311, so that the stick-shaped cosmetic material A can be smoothly guided into the cosmetic material holding portion 311.

[0155] In this way, the cosmetic material holding portion 311 of the core chuck member 310 has the connecting band 313 formed on a part of the circumferential direction and connecting at least one pair of claw pieces 312 in the circumferential direction, so that the multiple claw pieces 312 are prevented from spreading apart from each other. Therefore, the stick-shaped cosmetic material A can be stably held, and the stick-shaped cosmetic material A can be prevented from slipping out of the cosmetic material holding portion 311.

[0156] 9(b) and 9(c), the inner peripheral surface of the connecting belt 313 is formed into a curved shape so as to fit along the outer peripheral surface of the stick-shaped cosmetic material A. In other words, the inner peripheral surface of the connecting belt 313 and the inner peripheral surface of the claw piece 312 are formed continuously so as to fit along the outer peripheral surface of the stick-shaped cosmetic material A.

[0157] The connecting band 313 is formed of a thin film having a radial thickness of about 0.20 to 0.25 mm. The connecting band 313 has a radial thickness smaller than that of the claw piece 312. By forming the connecting band 313 from a thin film, it is possible to increase the degree of adhesion to the outer periphery of the stick-shaped cosmetic material A compared to the case where a thick connecting band is used, and it is possible to stably hold the stick-shaped cosmetic material A. In addition, since the claw piece 312 protrudes radially outward more than the connecting band 313, it is possible to position the claw piece 312 within the guide groove 321 of the front tube 320.

[0158] According to the above-described second embodiment, the same effects as those of the first embodiment are achieved.

[0159] <Third embodiment> Next, a stick-shaped cosmetic material dispensing container (hereinafter simply referred to as "dispensing container") 401 according to a third embodiment of the present invention will be described with reference to Fig. 10 to Fig. 13. Note that the same components as those in the above-mentioned embodiment are given the same reference numerals, and duplicated descriptions will be omitted as appropriate.

[0160] Fig. 10 is a cross-sectional view of a dispensing container 401 according to a third embodiment of the present invention, where (a) is a front cross-sectional view showing a state in which the core chuck member 410 is located at its rearmost position, (b) is a side cross-sectional view showing a state in which the core chuck member 410 is located at its forwardmost position, (c) is a cross-sectional view taken along line XC-XC in Fig. 10(b), (d) is a cross-sectional view showing only the front tube 420 in Fig. 10(c), and (e) is a cross-sectional view showing only the core chuck member 410 in Fig. 10(c). Fig. 11 is a view showing the core chuck member 410, where (a) is a front view, (b) is a side view, and (c) is a cross-sectional view showing an enlarged view of the cosmetic material holding portion 411 in the core chuck member 410. Fig. 12 is an enlarged view of the cosmetic material holding portion 411, where (a) is a front view, (b) is a side view, (c) is a plan view showing the state before the stick-shaped cosmetic material C is inserted, and (d) is a cross-sectional view taken along line XIID-XIID in Fig. 12(b) showing the state after the stick-shaped cosmetic material C has been inserted. Fig. 13 is a cross-sectional view showing modifications of the third embodiment of the present invention, where (a) shows a first modification, and (b) shows a second modification.

[0161] As shown in Fig. 10(a) and Fig. 10(b), the dispensing container 401 is a container capable of dispensing a stick-shaped cosmetic material C having a substantially elliptical cross-sectional shape. The stick-shaped cosmetic material C is a molded core formed into a stick shape and is used, for example, as an eyebrow, eyeliner, lip liner, etc. The stick-shaped cosmetic material C, like the stick-shaped cosmetic material A, is softer than the stick-shaped cosmetic material B. The outer diameter of the stick-shaped cosmetic material C is formed to be slightly larger than the inner diameter of the cosmetic material holding portion 411 described below. The ratio of the minor axis to the major axis of the stick-shaped cosmetic material C is approximately 1:2. Specifically, for example, the minor axis of the stick-shaped cosmetic material C is approximately 1.5 [mm] and the major axis is approximately 3.0 [mm].

[0162] The dispensing container 401 comprises a leading tube 420 having a through hole 420a through which the rod-shaped cosmetic material C can advance and retreat, a base tube 430 assembled to the leading tube 420 so as to be rotatable relative to the leading tube 420, a core chuck member 410 which holds the rod-shaped cosmetic material C, and a female threaded tube 440 which is arranged within the base tube 430 so as not to be rotatable relative to the base tube 430.

[0163] The front tube 420 is a tubular member in which a through hole 420a is formed penetrating in the axial direction. The front tube 420 has a knob 423 which is pinched by the user, and an insertion portion 424 which is formed continuous with the knob 423 in the axial direction and is inserted into the base tube 430. The cross-sectional shape of the through hole 420a is similar to the cross-sectional shape of the stick-shaped cosmetic material C, and is formed in a substantially elliptical shape. The knob 423 is formed in a tapered shape in the axial direction so that the outer diameter gradually decreases from the insertion portion 424 side toward the tip.

[0164] On the outer circumferential surface of the fitting portion 424, there are formed an annular fitting protrusion 425 that fits into a fitting recess 432 (described later) formed in the base tube 430, and an O-ring groove 426 in which the O-ring 402 is attached. The O-ring 402 is provided in a compressed state between the front tube 420 and the base tube 430, and generates an appropriate resistance when the front tube 420 and the base tube 430 are rotated relative to each other. This improves the operability of the user.

[0165] The through hole 420a extends along the axial direction and has a guide groove 421 that protrudes radially outward to guide the core chuck member 10 along the axial direction, a first wall-like portion 422a against which the outer peripheral surface of the rod-shaped cosmetic material C slides along the axial direction, and a second wall-like portion 422b against which the connecting belt 413 described later slides along the axial direction as the core chuck member 410 moves forward and backward.

[0166] 10(c), the guide grooves 421 are linear grooves that are provided in a plurality (six in this example) at intervals in the circumferential direction. The guide grooves 421 are arranged at uneven intervals in the circumferential direction so as to correspond to the positions of the claw pieces 412.

[0167] The inner peripheral surface of the guide groove 421 is curved so as to form a part of an arc centered on the central axis. A claw piece 412 (described later) of the core chuck member 410 is positioned in the guide groove 421, and an engaging ridge portion 416 (described later) engages with the claw piece 412. A first wall portion 422a or a second wall portion 422b is formed between adjacent guide grooves 421.

[0168] Guide groove 421 is formed up to rear end surface 420c of front tube 420. Guide groove 421 is formed up to just before front end opening 420b of through hole 420a without reaching it.

[0169] The guide groove 421 has a pair of first guide grooves 421a arranged in parallel adjacent to each other, and a pair of second guide grooves 421b arranged on the same straight line so as to face each other across the central axis. The first guide groove 421a and the second guide groove 421b are arranged so as to face each other across the central axis.

[0170] The pair of first guide grooves 421a are provided in two sets facing each other across the central axis. The first guide grooves 421a are arranged side by side along the longitudinal axis of the stick-shaped cosmetic material C.

[0171] The second guide groove 421b is provided between two pairs of the first guide grooves 421a. The second guide groove 421b is disposed along the minor axis of the stick-shaped cosmetic material C.

[0172] As shown in FIG. 10(d), a plurality of first wall portions 422a are provided in the circumferential direction. Here, the first wall portions 422a are provided at two locations in the circumferential direction. The first wall portions 422a are provided between a pair of first guide grooves 421a adjacent to each other in the circumferential direction. A pair of the first wall portions 422a are provided to face each other across the central axis. The pair of first wall portions 422a are provided to sandwich the stick-shaped cosmetic material C in the minor axis direction. The first wall portions 422a are not limited to a pair facing each other as long as they are capable of supporting the outer circumferential surface of the stick-shaped cosmetic material C.

[0173] A plurality of second wall-shaped portions 422b are provided in the circumferential direction. Here, the second wall-shaped portions 422b are provided at four locations in the circumferential direction. The second wall-shaped portions 422b are provided between the first guide groove 421a and the second guide groove 421b that are adjacent in the circumferential direction. The second wall-shaped portions 422b are provided in two pairs facing each other across the central axis. The two pairs of second wall-shaped portions 422b face the outer circumferential surface of the connecting belt 413. As long as the second wall-shaped portions 422b face the outer circumferential surface of the connecting belt 413, they are not limited to being two opposing pairs.

[0174] As shown in FIG. 10(d), the inner diameter dimension α3-α3 between a pair of opposing first wall portions 422a is smaller than the inner diameter dimension β3-β3 between two pairs of opposing second wall portions 422b (α3-α3<β3-β3).

[0175] The base tube 430 is a member formed in a bottomed cylindrical shape that houses the core chuck member 410 and has an accommodation hole 433 into which the fitting portion 424 of the front tube 420 is fitted and into which the female thread tube 440 is inserted. The accommodation hole 433 is provided with an annular fitting recess 432 into which the fitting protrusion 425 of the front tube 420 is fitted.

[0176] As shown in FIGS. 11(a) and 11(b), the core chuck member 410 includes a cosmetic material holding portion 411 that holds a rod-shaped cosmetic material C, and a base portion 415 on which the cosmetic material holding portion 411 stands.

[0177] The cosmetic material holding portion 411 comprises a plurality of (six in this case) claw pieces 412 which extend along the axial direction of the stick-shaped cosmetic material C and hold the outer peripheral surface of the stick-shaped cosmetic material C, a base portion end surface 415a (see Figure 11(c)) which serves as a bottom surface portion which holds the bottom of the stick-shaped cosmetic material C, and a connecting band 413 which serves as a band portion formed in part of the circumferential direction and which connects at least a pair of claw pieces 412 in the circumferential direction at a position axially spaced from the base portion end surface 415a.

[0178] As shown in Fig. 11(c), the claw pieces 412 are erected in the axial direction from the base end surface 415a. The outer peripheral surface of the claw pieces 412 is formed with a smaller diameter than the outer peripheral surface of the engaging ridge portion 416 of the base portion 415. The inner peripheral surface of the claw pieces 412 is formed in a curved shape so as to fit along the outer peripheral surface of the stick-shaped cosmetic material C. Six claw pieces 412 are provided so as to sandwich the stick-shaped cosmetic material C from the outer periphery. The multiple claw pieces 412 are arranged at uneven intervals in the circumferential direction.

[0179] The claw pieces 412 have a plurality of short claw pieces 412b as first claw pieces having a short length from the base end surface 415a, and a plurality of long claw pieces 412a as second claw pieces having a longer length from the base end surface 415a than the short claw pieces 412b. As shown in Fig. 12(c), the pair of long claw pieces 412a and one short claw piece 412b, together with the connecting band 413, respectively constitute holding pieces 411a, 411b.

[0180] The short claw pieces 412b are provided on both ends of the long axis of the stick-shaped cosmetic material C. The short claw pieces 412b hold the stick-shaped cosmetic material C from both ends of the long axis.

[0181] Two long claw pieces 412a are provided between the short claw pieces 412b. The long claw pieces 412a are provided so that two of them face each other across the central axis. The long claw pieces 412a are provided at positions closer to the central axis than the short claw pieces 412b. The long claw pieces 412a are formed to be thicker than the short claw pieces 412b.

[0182] 10(b), when the core chuck member 410 is at the forward limit, the short claw piece 412b on the short axis side can be made shorter than the long claw piece 412a to reduce the outer diameter of the short axis side of the leading tube 420 in the tip direction. This allows the taper of the short axis side of the pinched portion 423 of the leading tube 420 to become smaller toward the tip. A smaller outer diameter on the tip side of the leading tube 420 can prevent the tip of the leading tube 420 from hitting the face when applying makeup around the eyes, making the dispensing container 401 easier to use.

[0183] As shown in Figs. 12(a) and 12(c), each long claw piece 412a has a tapered surface 412d that is inclined so as to move away from the outer circumferential surface of the stick-shaped cosmetic material C toward the tip end.

[0184] The tapered surface 412d is inclined so that the inner diameter, which is the distance between the pair of opposing long claws 412a, increases toward the tip. The tapered surface 412d makes it easier to insert the stick-shaped cosmetic material C into the cosmetic material holding portion 411, and prevents the outer periphery of the rear end of the stick-shaped cosmetic material C from being scraped by the long claws 412a when inserting the stick-shaped cosmetic material C.

[0185] The base end surface 415a is provided at the axial tip of the base 415. The base end surface 415a is formed in a shape similar to the cross-sectional shape of a stick-shaped cosmetic material C, which is formed to have a major axis and a minor axis. The bottom surface of the stick-shaped cosmetic material C abuts against the base end surface 415a.

[0186] In one holding piece 411a, a pair of connecting bands 413 are provided to connect adjacent short claw pieces 412b and long claw pieces 412a in the circumferential direction. In the other holding piece 411b, a pair of connecting bands 413 are provided to connect a pair of long claw pieces 412a provided on the same straight line and a short claw piece 412b provided therebetween in the circumferential direction. In other words, the connecting band 413 connects the three claw pieces 412 constituting the holding piece 411a or the holding piece 411b, but does not connect the holding piece 411a and the holding piece 411b. The holding pieces 411a and 411b are formed by a plurality of claw pieces 412 adjacent to each other at positions spaced apart in the circumferential direction and a plurality of connecting bands 413.

[0187] The connecting belt 413 is provided at a position spaced apart from the base end surface 415a in the axial direction. As a result, a space 414 is formed between the base end surface 415a and the connecting belt 413. The provision of the space 414 allows the outer peripheral surface of the stick-shaped cosmetic material C inserted into the cosmetic material holding part 411 to bite into the space 414, thereby strengthening the engagement of the stick-shaped cosmetic material C with the cosmetic material holding part 411. Therefore, even if the stick-shaped cosmetic material C is about to move axially forward due to an impact or the like, the outer peripheral surface of the stick-shaped cosmetic material C gets caught on the rear end surface of the connecting belt 413, preventing the stick-shaped cosmetic material C from coming off.

[0188] Further, the plurality of claw pieces 412 are arranged at unequal intervals in the circumferential direction, and the plurality of guide grooves 421 are arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 412. As a result, when the core chuck member 410 is inserted into the leading tube 420, the assembly angle between the claw pieces 412 and the through hole 420a around the central axis is determined so that the connecting band 413 is positioned on the second wall-shaped portion 422b. That is, the plurality of claw pieces 412 arranged at unequal intervals in the circumferential direction and the plurality of guide grooves 421 arranged at unequal intervals in the circumferential direction so as to correspond to the positions of the plurality of claw pieces 412 constitute an assembly angle determination mechanism that determines the assembly angle between the claw pieces 412 and the through hole 420a around the central axis so that the connecting band 413 is positioned on the second wall-shaped portion 422b when the core chuck member 410 is inserted into the leading tube 420. Furthermore, the rod-shaped cosmetic material C is formed so that its cross-sectional shape has a long axis and a short axis, and the configuration in which the base end face 415a is formed in a shape similar to the cross-sectional shape of the rod-shaped cosmetic material C and the configuration in which the through-hole 420a is formed in a shape similar to the cross-sectional shape of the base end face 415a also constitute an assembly angle regulating mechanism. Therefore, the connecting belt 413 is prevented from being inserted into a position where it cannot be inserted, and damage to the connecting belt 413 can be prevented when the core chuck member 410 is inserted into the leading tube 420.

[0189] As shown in Figures 10(d) and 10(e), the outer diameter dimension θ3-θ3 of two pairs of connecting bands 413 facing each other across the central axis is larger than the inner diameter dimension α3-α3 of the multiple first wall-shaped portions 422a and smaller than the inner diameter dimension β3-β3 of the multiple second wall-shaped portions 422b (α3-α3<θ3-θ3<β3-β3).

[0190] That is, the clearance between the inner peripheral surface (inner diameter dimension α3-α3) of the first wall portion 422a, into which the position where the connecting band 413 is not provided is inserted, and the outer peripheral surface of the stick-shaped cosmetic material C is set to be smaller than the clearance between the inner peripheral surface (inner diameter dimension β3-β3) of the second wall portion 422b, into which the connecting band 413 is inserted, and the outer peripheral surface of the stick-shaped cosmetic material C. Moreover, the inner diameter dimension β3-β3 of the opposing second wall portion 422b is set to be larger than the outer diameter dimension θ3-θ3 of the opposing connecting band 413.

[0191] Therefore, similarly to the first and second embodiments described above, core breakage due to inclination of the stick-shaped cosmetic material C can be prevented, and the advancement and retreat of the stick-shaped cosmetic material C can be stabilized, and since the connecting belt 413 is always guided by the second wall-shaped portion 422b, the core chuck member 410 can slide stably when advancing and retreating.

[0192] The connecting band 413 is provided at a position spaced axially from the tip of the claw piece 412 toward the base end face 415a. As a result, a claw piece elastic portion 412e is formed on the tip side of the claw piece 412 from the connecting band 413. The claw piece elastic portion 412e expands toward the outer periphery when the stick-shaped cosmetic material C is inserted into the cosmetic material holding portion 411, so that the stick-shaped cosmetic material C can be smoothly guided into the cosmetic material holding portion 611.

[0193] In this way, the cosmetic material holding portion 411 of the core chuck member 410 has connecting bands 413 that connect the multiple claw pieces 412 in the circumferential direction at a position spaced from the base portion end face 415a that holds the bottom of the stick-shaped cosmetic material C, thereby preventing the multiple claw pieces 412 from spreading apart from each other. Therefore, the holding force of the claw pieces 412 to hold the stick-shaped cosmetic material C is reinforced by the connecting bands 413, so that the stick-shaped cosmetic material C can be stably held and the stick-shaped cosmetic material C can be prevented from slipping out of the cosmetic material holding portion 611.

[0194] The inner peripheral surface of the connecting belt 413 is formed in a curved shape so as to fit along the outer peripheral surface of the stick-shaped cosmetic material C. In other words, the inner peripheral surface of the connecting belt 413 and the inner peripheral surface of the claw piece 412 are formed continuously so as to fit along the outer peripheral surface of the stick-shaped cosmetic material C.

[0195] The connecting band 413 is formed of a thin film having a radial thickness of about 0.20 to 0.25 mm. The connecting band 413 has a radial thickness smaller than that of the claw piece 412. By forming the connecting band 413 from a thin film, it is possible to increase the degree of adhesion to the outer periphery of the stick-shaped cosmetic material C compared to the case where a thick connecting band is used, and it is possible to stably hold the stick-shaped cosmetic material C. In addition, since the claw piece 412 protrudes radially outward more than the connecting band 413, it is possible to position the claw piece 412 within the guide groove 421 of the front tube 420.

[0196] As shown in Figures 11(a) and 11(b), the base portion 415 has an engagement rib portion 416 that circumferentially engages with the guide groove 421, and a male thread portion 417 that is formed continuously from the engagement rib portion 416 in the axial direction.

[0197] The engagement rib 416 is formed on the outer periphery of the portion between the base end surface 415a on which the claw 412 is erected and the male screw portion 417. The engagement rib 416 is formed linearly along the axial direction. The engagement rib 416 is formed continuously from the claw 412 in the axial direction. The engagement rib 416 engages with the guide groove 421 of the front tube 420, thereby restricting the relative rotation in the circumferential direction between the front tube 420 and the core chuck member 410. The engagement rib 416 has a first engagement rib 416a formed continuously from the long claw 412a and a second engagement rib 416b formed continuously from the short claw 412b. A groove is formed between the adjacent first engagement ribs 416a up to the groove end surface 419. The groove end surface 419, in a state in which it abuts against a rear end surface 420c of a first wall-shaped portion 422a of the front tube 420, defines the forward movement limit of the core chuck member 410.

[0198] The male thread portion 417 is provided in a plurality of positions so as to protrude from the engaging rib portion 416 in the axial direction to the outer periphery of a portion formed with a smaller diameter than the engaging rib portion 416. The male thread portion 417 is provided at a plurality of positions (two positions in this example) in the circumferential direction. The male thread portion 417 screws into the female thread portion 443 of the female thread tube 440.

[0199] The female threaded tube 440 is a cylindrical member made of resin and formed with a female threaded portion 443 that penetrates in the axial direction and into which the male threaded portion 417 of the core chuck member 410 screws. The female threaded tube 440 has a rear end surface 444 that abuts against a step portion 435 of the base tube 430 when inserted into the base tube 430, and a front end surface 442 that abuts against a rear end surface 420c of the front tube 420 when the front tube 420 is assembled to the base tube 430.

[0200] A plurality of axially extending vertical ribs (not shown) are formed at equal intervals in the circumferential direction on the outer circumferential surface of the female thread tube 440. The vertical ribs engage with knurls (not shown) formed on the inner circumferential surface of the base tube 430, and function as a rotation stopper that prevents the female thread tube 440 from rotating relative to the base tube 430.

[0201] When the leading tube 420 and the base tube 430 are rotated relative to each other in a state in which the male thread portion 417 of the core chuck member 410 is screwed into the female thread portion 443 of the female thread tube 440, the core chuck member 410 rotates integrally with the leading tube 420, and the female thread tube 440 rotates integrally with the base tube 430, so that the core chuck member 410 and the base tube 430 rotate relative to each other. As a result, the male thread portion 417 of the core chuck member 410 rotates relative to the female thread portion 443, so that the core chuck member 410 moves relative to the female thread tube 440 in the axial direction. That is, a payout mechanism is formed that advances and retracts the rod-shaped cosmetic material C held by the core chuck member 410 from the tip opening 420b of the through hole 420a of the leading tube 420 by the relative rotation between the leading tube 420 and the base tube 430.

[0202] In this way, in the dispensing container 401, the female threaded tube 440 and the core chuck member 410 form a dispensing mechanism that dispensing the rod-shaped cosmetic material C in the axial direction, and when the front tube 420 and the base tube 430 are rotated relative to each other, the core chuck member 410 advances and retreats in the axial direction within the front tube 420 and the base tube 430, and the rod-shaped cosmetic material C also advances and retreats in accordance with the advancement and retreat of the core chuck member 410.

[0203] Specifically, when the user rotates the front tube 420 and the base tube 430 relative to each other in the forward direction, the core chuck member 410 moves axially toward the tip opening 420b of the front tube 420, advancing the stick-shaped cosmetic material C. This causes the stick-shaped cosmetic material C to be fed out from the tip opening 420b. On the other hand, when the user rotates the front tube 420 and the base tube 430 relative to each other in the reverse direction, the core chuck member 410 moves in the reverse direction, retracting the stick-shaped cosmetic material C. This causes the stick-shaped cosmetic material C to be fed back.

[0204] The engaging ridge portion 416 of the core chuck member 410 is formed so as not to be able to insert the female threaded tube 440. Therefore, as the core chuck member 410 retracts, the engaging ridge portion 416 abuts against the female threaded tube 440, and the retraction limit of the core chuck member 410 is determined.

[0205] According to the above-described third embodiment, the same effects as those of the first and second embodiments are achieved.

[0206] <First Modification> Next, a core chuck member 510 and a front tube 520 as a stick-shaped cosmetic material holding member according to a first modified example of the third embodiment of the present invention will be described with reference to Fig. 13(a).

The pair of second wall portions 522b face the outer circumferential surface of the connecting belt 513.

[0212] The connecting band 513 is provided in a pair so as to connect the adjacent pair of long claw pieces 412a in the circumferential direction. The connecting band 513 is provided along the minor axis of the stick-shaped cosmetic material C.

[0213] Similarly, the first modified example also provides the same effects as the third embodiment.

[0214] <Second Modification> Next, a core chuck member 610 and a front tube 620 as a stick-shaped cosmetic material holding member according to a second modified example of the third embodiment of the present invention will be described with reference to Fig. 13(b). Note that the same reference numerals are used to designate the same components as those in the above-described embodiment or each modified example, and duplicated descriptions will be omitted as appropriate.

[0215] FIG. 13(a) is a cross-sectional view showing a second modified example of the third embodiment of the present invention.

[0216] The core chuck member 610 according to this first modification is different from the first modification of the third embodiment described above in that the connecting band 613 is provided so as to extend along the longitudinal axis of the rod-shaped cosmetic material C.

[0217] A plurality of first wall portions 622a are provided in the circumferential direction. Here, the first wall portions 622a are provided at two locations in the circumferential direction. The first wall portions 622a are provided between a pair of first guide grooves 421a adjacent to each other in the circumferential direction.

[0220] Similarly, the second modified example also provides the same effects as the third embodiment.
