Description

[Technical Field]

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

[0002] Patent Document 1 describes a pencil that includes a lead, a cartridge that houses the lead, and a protective cap that has a lead shaping device. The shaping device is a lead sharpener located inside the protective cap. The lead sharpener is biased in the axial direction of the protective cap by a coil spring.

[0003] The pencil has a cylindrical handle that holds the lead and a protective cap that is attached to the handle. The protective cap has a blade that sharpens the lead and a guide template that guides the lead toward the blade. A spring is disposed inside the protective cap, and the lead is biased by the spring toward the side opposite the bottom of the handle. When the protective cap is attached to the handle, the lead biased by the spring is guided by the guide template and sharpened by the blade. In this way, the lead is sharpened by the blade when the protective cap is attached to the handle. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2011-502662 Summary of the Invention [Problem to be solved by the invention]

[0005] In the pencil described above, the stick-shaped cosmetic material is shave off by the blade while being biased toward the guide template by a spring. Therefore, the biased stick-shaped cosmetic material is shave off every time the protective cap is attached to the handle, resulting in the problem of unnecessary shaving off of the stick-shaped cosmetic material and rapid consumption of the lead. Therefore, it is necessary to prevent unnecessary shaving off of the stick-shaped cosmetic material and to appropriately shave off the stick-shaped cosmetic material.

[0006] An object of the present disclosure is to provide a container for dispensing a stick-shaped cosmetic material that can appropriately shave off a stick-shaped cosmetic material while preventing the stick-shaped cosmetic material from being shave off in an unnecessary manner. [Means for solving the problem]

[0007] (1) A stick-shaped cosmetic dispensing container according to the present disclosure includes a container body that stores a stick-shaped cosmetic and is capable of dispensing the stick-shaped cosmetic from an opening at the tip of the container body, a cap that is removably attached to the container body while covering the opening of the container body, and a sharpener provided inside the cap. The sharpener is rotatable in the circumferential direction of the cap relative to the cap. When the cap is attached to or detached from the container body, the sharpener sharpens the stick-shaped cosmetic while rotating in the circumferential direction of the cap relative to the cap.

[0008] This stick-shaped cosmetic material dispensing container comprises a container body, a cap, and a sharpener, with the sharpener provided inside the cap. The cap is detachable from the container body, and the sharpener is rotatable in the circumferential direction of the cap. The sharpener sharpens the stick-shaped cosmetic material while rotating in the circumferential direction of the cap when the cap is attached to or detached from the container body. Because the stick-shaped cosmetic material is sharpened by the sharpener rotating in the circumferential direction of the cap, the stick-shaped cosmetic material can be appropriately sharpened along the circumferential direction of the stick-shaped cosmetic material. This prevents the stick-shaped cosmetic material from being wasted, and prevents the problem of the stick-shaped cosmetic material being consumed too quickly.

[0009] (2) In (1) above, the cap may be cylindrical with a bottom, and the container for dispensing a stick-shaped cosmetic material may include a spring disposed inside the cap that biases the sharpener toward the side opposite the bottom of the cap. In this case, the sharpener is biased toward the side opposite the bottom of the cap by the spring. Therefore, when the cap is attached to the container body, the sharpener is biased toward the stick-shaped cosmetic material, and the sharpener rotating in the circumferential direction can sharpen the stick-shaped cosmetic material more appropriately.

[0010] (3) In (1) or (2) above, the cap may have a first uneven portion on its inner surface, and the container body may have a second uneven portion provided on the outer surface of the container body that engages with the first uneven portion when the cap is attached to the container body. The second uneven portion may engage with the first uneven portion when the sharpener is in contact with the stick-type cosmetic material. In this case, when the cap is attached to the container body and the second uneven portion engages with the first uneven portion, the sharpener is in contact with the stick-type cosmetic material. Therefore, it is possible to sharpen the stick-type cosmetic material in the circumferential direction not only when attaching the cap but also when removing the cap. This allows the stick-type cosmetic material to be sharpened more reliably and appropriately.

[0011] (4) In any of (1) to (3) above, the sharpener may have multiple blades arranged along the circumferential direction of the cap. The multiple blades may sharpen the stick-shaped cosmetic material as the sharpener rotates in the circumferential direction relative to the cap. In this case, by rotating the multiple blades arranged along the circumferential direction to sharpen the stick-shaped cosmetic material, the stick-shaped cosmetic material can be reliably sharpened even if the amount of rotation of the sharpener relative to the cap is small. Therefore, the mechanism for rotating the sharpener can be simplified. [Effects of the Invention]

[0012] According to the present disclosure, it is possible to prevent unnecessary scraping of the stick-shaped cosmetic material and scrape the stick-shaped cosmetic material appropriately. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of a stick-type cosmetic material dispensing container according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be simplified or exaggerated as appropriate for ease of understanding, and the dimensional proportions and the like are not limited to those shown in the drawings.

[0015] Fig. 1(a) is a side view showing a stick-type cosmetic material dispensing container 1 according to this embodiment. Fig. 1(b) is a side view showing the stick-type cosmetic material dispensing container 1 with its cap 2 removed. As shown in Figs. 1(a) and 1(b), the stick-type cosmetic material dispensing container 1 has a cap 2 and a container body 3 to which the cap 2 is detachable.

[0016] Fig. 2 is a cross-sectional view taken along line AA in Fig. 1(a). As shown in Figs. 1(a), 1(b), and 2, the container body 3 contains a stick-shaped cosmetic material M. The stick-shaped cosmetic material M is in a solid form. One example of the stick-shaped cosmetic material M is an eyeliner. However, the stick-shaped cosmetic material M may also be an eyebrow liner, and the type of the stick-shaped cosmetic material M is not particularly limited.

[0017] The cap 2 has a bottomed tubular shape (for example, a bottomed cylindrical shape). Some parts of the stick-type cosmetic material dispensing container 1, including the cap 2, are tubular. When the parts of the stick-type cosmetic material dispensing container 1 are assembled, the directions in which the axes L of the multiple tubular parts extend are the same. Hereinafter, the direction in which this axis L extends is referred to as the axial direction D1. For example, the axial direction D1 coincides with the longitudinal direction of the stick-type cosmetic material dispensing container 1.

[0018] In this embodiment, "front," "front side," and "forward" refer to the direction from the container body 3 toward the cap 2 in the axial direction D1, and "rear," "rear side," and "rearward" refer to the direction from the cap 2 toward the container body 3 in the axial direction D1. "Radial direction" refers to the direction toward the axis L or the direction away from the axis L in a plane perpendicular to the axis L. "Radially outward" refers to the direction away from the axis L in the radial direction, and "radially inward" refers to the direction toward the axis L in the radial direction. "Circumferential direction" refers to the direction along a ring centered on the axis L (direction of rotation). In this embodiment, the direction in which the stick-shaped cosmetic material M is dispensed is the forward direction (forward movement direction), and the opposite direction is the rearward direction.

[0019] The stick-shaped cosmetic material dispensing container 1 has a stick shape extending in an axial direction D1. The stick-shaped cosmetic material dispensing container 1 dispenses a stick-shaped cosmetic material M. For example, the stick-shaped cosmetic material dispensing container 1 is a pen-type container that dispenses (pushes out) the stick-shaped cosmetic material M contained inside the stick-shaped cosmetic material dispensing container 1. Inside the stick-shaped cosmetic material dispensing container 1, the stick-shaped cosmetic material M extends in the axial direction D1.

[0020] The container body 3 contains a stick-shaped cosmetic material M. The container body 3 is capable of dispensing the stick-shaped cosmetic material M from an opening 4b provided at the tip (front end) of the container body 3. In this embodiment, the container body 3 has a front tube 4 that contains the stick-shaped cosmetic material M, a middle tube 5 that engages with the front tube 4 in the axial direction D1, and a rear tube 6 that engages with the middle tube 5 in the axial direction D1 and extends from the middle tube 5 in the opposite direction to the front tube 4.

[0021] The front tube 4 has an opening 4b through which the stick-shaped cosmetic material M is exposed when the cap 2 is removed from the container body 3, an inclined surface 4c that is inclined with respect to the axial direction D1 so that the diameter of the front tube 4 increases with increasing distance from the opening 4b in the axial direction D1, and an insertion portion 4d that is inserted into the middle tube 5. For example, the insertion portion 4d is cylindrical. The middle tube 5 has a front tube portion 5b that is exposed when the cap 2 is removed and a rear tube portion 5c that is inserted into the rear tube 6. The front tube 4 is attached to the middle tube 5 so as to be rotatable relative to it. The rear tube 6 is cylindrical and has a bottom 6b located on the opposite side from the front tube 4. The middle tube 5 is engaged with the rear tube 6 so as to be rotatable synchronously with each other.

[0022] The stick-shaped cosmetic material dispensing container 1 has a female screw member 7 located inside the middle cylinder 5, a movable body 8 that holds the stick-shaped cosmetic material M and moves along the axial direction D1, a spring 9 located inside the front cylinder 4 and the middle cylinder 5, and an O-ring 10. The female screw member 7 is inserted into the front cylinder 4 and is connected to the middle cylinder 5 inside the middle cylinder 5 so as to be synchronously rotatable.

[0023] The female screw member 7 has, for example, a spring portion 7b located inside the middle cylinder 5. The spring portion 7b is provided on the rear side of the female screw member 7. The spring portion 7b has a cylindrical portion 7c extending in the axial direction D1 and a slit 7d formed in a spiral shape in the cylindrical portion 7c, which penetrates the female screw member 7 in the radial direction. The spring portion 7b is able to expand and contract in the axial direction D1 due to the slit 7d formed in a spiral shape in the cylindrical portion 7c. The female screw member 7 has, for example, a cylindrical shape. The female screw member 7 has a female screw 7f inside. For example, the female screw 7f is formed on the front side of the female screw member 7.

[0024] The movable body 8 has a holding portion 8b that holds the stick-shaped cosmetic material M, and a screw portion 8c that extends rearward from the holding portion 8b. The holding portion 8b holds the rear portion of the stick-shaped cosmetic material M. The holding portion 8b circumferentially engages with the front tube 4 in the internal space 4f of the front tube 4. This allows the movable body 8 to be synchronously rotatable with the front tube 4. The screw portion 8c has a male screw 8d that screws into the female screw 7f inside the female screw member 7.

[0025] The spring 9 is disposed between the front tube 4 and the female screw member 7. The front tube 4 has a step 4g in its internal space 4f that faces the spring 9 in the axial direction D1. The inner diameter of the front tube 4 in front of the step 4g is smaller than the inner diameter of the front tube 4 behind the step 4g. The female screw member 7 has a flange 7g that protrudes radially outward from the female screw member 7. The spring 9 is interposed between the step 4g and the flange 7g, and urges the female screw member 7 rearward.

[0026] The stick-type cosmetic material dispensing container 1 has, for example, a plurality of O-rings 10. For example, an O-ring 10 is disposed between the outer peripheral surface of the front tube 4 and the inner peripheral surface of the middle tube 5, and between the outer peripheral surface of the middle tube 5 and the inner peripheral surface of the cap 2. An O-ring 10 is fitted into a recess 4h formed in the outer peripheral surface of the insertion portion 4d of the front tube 4, and into a recess 5d formed in the outer peripheral surface of the front tube portion 5b of the middle tube 5. By disposing the O-rings 10 in this manner, the airtightness of the stick-type cosmetic material dispensing container 1 can be improved. However, the number and locations of the O-rings 10 are not limited to the above example and can be changed as appropriate.

[0027] The cap 2 has a first uneven portion 2c on its inner surface 2b, and the middle cylinder 5 has a second uneven portion 5g on its outer surface 5f. The second uneven portion 5g engages with the first uneven portion 2c. Figures 1(b) and 2 show an example in which the first uneven portion 2c is a concave portion and the second uneven portion 5g is a convex portion. However, the first uneven portion 2c may be a convex portion and the second uneven portion 5g may be a concave portion. For example, the first uneven portion 2c is an annular concave portion extending in the circumferential direction of the cap 2. The second uneven portion 5g has a circular shape. The first uneven portion 2c rides backward over the second uneven portion 5g, thereby engaging the cap 2 with the middle cylinder 5 and attaching the cap 2 to the container body 3.

[0028] With the stick-type cosmetic material dispensing container 1 configured as described above, it is possible to apply the stick-type cosmetic material M by removing the cap 2. More specifically, when the cap 2 is removed from the container body 3 and the rear tube 6 is rotated in one direction (for example, clockwise) relative to the front tube 4, the rear tube 6, the middle tube 5, and the female screw member 7 rotate in one direction relative to the front tube 4 and the moving body 8. At this time, the screwing action of the female screw 7f and the male screw 8d causes the moving body 8 to move forward relative to the female screw member 7, and the stick-type cosmetic material M is dispensed forward from the opening 4b, and the stick-type cosmetic material M is ready for use.

[0029] When the rear tube 6 is rotated relative to the front tube 4 in the opposite direction (for example, counterclockwise) to the one direction described above, the middle tube 5 and female screw member 7 rotate together with the rear tube 6 relative to the front tube 4 and moving body 8 in the opposite direction. At this time, the screwing action of the female screw 7f and the male screw 8d causes the moving body 8 to move rearward relative to the female screw member 7, and the stick-shaped cosmetic material M is fed rearward from the opening 4b. Then, the cap 2 is attached to the container body 3 (middle tube 5), completing the use of the stick-shaped cosmetic material dispensing container 1.

[0030] Fig. 3 is a cross-sectional view of the cap 2 showing the internal structure of the cap 2. As shown in Figs. 2 and 3, the cap 2 is detachably attached to the container body 3 in a state where it covers the opening 4b of the container body 3. The stick-shaped cosmetic material dispensing container 1 has a sharpener 11 provided inside the cap 2 and a spring 12 that biases the sharpener 11.

[0031] The cap 2 has a cylindrical portion 2d extending in the axial direction D1, a bottom portion 2f located at one end of the cylindrical portion 2d in the axial direction D1, and an opening 2g located at the other end of the cap 2 in the axial direction D1. The cylindrical portion 2d has a plurality of ridges 2h on its inner surface that are aligned along the circumferential direction and extend in the axial direction D1. The ridges 2h extend from the openings 2g of the cap 2 toward the bottom portion 2f. The ridges 2h engage with the outer peripheral surface of the inner cylinder 5 when the cap 2 is attached to the container body 3.

[0032] The spring 12 is disposed between the sharpener 11 and the bottom 2f of the cap 2. The spring 12 biases the sharpener 11 toward the side opposite the bottom 2f of the cap 2 (toward the opening 2g). The cap 2 has a protrusion 2j on its inner surface 2b, and the sharpener 11 biased by the spring 12 comes into contact with the protrusion 2j. The protrusion 2j is, for example, an annular protrusion formed on the rear side of the cap 2 (toward the opening 2g).

[0033] The cap 2 and the sharpener 11 will be described in more detail below. Fig. 4(a) is a cross-sectional view showing the cap 2. Fig. 4(b) is a cross-sectional view taken along line BB in Fig. 4(a). As shown in Figs. 3, 4(a) and 4(b), the cap 2 has an arrangement region 2k therein where the sharpener 11 is arranged.

[0034] The arrangement region 2k is the region from the bottom 2f to the convex portion 2j inside the cap 2. The arrangement region 2k has a large diameter portion 2p and a small diameter portion 2q whose inner diameter is smaller than that of the large diameter portion 2p. The large diameter portion 2p extends from the convex portion 2j toward the bottom 2f, and the small diameter portion 2q is located between the large diameter portion 2p and the bottom 2f.

[0035] The cap 2 has a spiral groove 2r on its inner surface 2b for rotating the sharpener 11 relative to the cap 2. The sharpener 11 rotates relative to the cap 2 along the spiral groove 2r. For example, the circumferential length of the spiral groove 2r is less than half the circumferential length of the inner surface 2b of the cap 2. In this case, the sharpener 11 rotates less than halfway around the axis L of the cap 2.

[0036] The cap 2 has, for example, a plurality of (for example, two) spiral grooves 2r. In this case, the two spiral grooves 2r may be formed at positions on either side of the axis L. In this case, it is possible to stabilize the rotation of the sharpener 11 relative to the cap 2. In a cross section perpendicular to the axis L, the two spiral grooves 2r are arranged, for example, at positions symmetrical with respect to the axis L.

[0037] Fig. 5(a) is a side view showing the sharpener 11. Fig. 5(b) is a side view showing the sharpener 11 seen from a different direction than Fig. 5(a). As shown in Figs. 2, 3, 5(a) and 5(b), the sharpener 11 has, for example, a cylindrical shape. The sharpener 11 is rotatable relative to the cap 2 in the circumferential direction of the cap 2.

[0038] The sharpener 11 has an expanded diameter portion 11b located at one end in the axial direction D1 of the sharpener 11. The expanded diameter portion 11b protrudes radially outward from the outer peripheral surface of the sharpener 11. The expanded diameter portion 11b abuts against the protrusion 2j of the cap 2 when the sharpener 11 is biased by the spring 12. The expanded diameter portion 11b abuts against the protrusion 2j in the axial direction D1, thereby preventing the sharpener 11 from coming off the cap 2.

[0039] The sharpener 11 has a protrusion 11c that fits into the spiral groove 2r of the cap 2. The protrusion 11c is, for example, disk-shaped. The sharpener 11 has a reduced diameter portion 11d located at the end opposite the expanded diameter portion 11b, and the protrusion 11c is formed on the reduced diameter portion 11d. The sharpener 11 has, for example, a plurality of (two, for example) protrusions 11c. The protrusions 11c move along the spiral groove 2r. The movement of the protrusions 11c along the spiral groove 2r causes the sharpener 11 to rotate relative to the cap 2. For example, the two protrusions 11c may be arranged at positions sandwiching the axis L.

[0040] Fig. 6 is a cross-sectional view taken along line CC in Fig. 5(a). As shown in Fig. 2, Fig. 3, and Fig. 6, the sharpener 11 has a first internal space 11f into which the stick-shaped cosmetic material M and the front tube 4 fit, and a second internal space 11g into which the spring 12 fits. The first internal space 11f is located closer to the opening 2g of the cap 2 (opposite the bottom 2f) than the second internal space 11g.

[0041] The sharpener 11 has a first opening 11h located at one end in the axial direction D1 of the sharpener 11, and a second opening 11j located at the other end in the axial direction D1 of the sharpener 11. A first internal space 11f extends from the first opening 11h, and a second internal space 11g extends from the second opening 11j.

[0042] The sharpener 11 has a first inner surface 11s that defines a first internal space 11f and a second inner surface 11t that defines a second internal space 11g. For example, the first inner surface 11s and the second inner surface 11t are cylindrical. The inner diameter of the first inner surface 11s decreases with increasing distance from the first opening 11h, while the inner diameter of the second inner surface 11t is constant.

[0043] The sharpener 11 has a partition wall 11k that separates the first internal space 11f and the second internal space 11g. The partition wall 11k has a recess 11p that is recessed toward the bottom 2f of the cap 2. The recess 11p has, for example, a conical shape. The recess 11p approaches the bottom 2f of the cap 2 as it approaches the axis L.

[0044] In a cross section of the sharpener 11 taken along a plane extending in the axial direction D1 and the radial direction of the sharpener 11, the recess 11p has a V-shape protruding from the bottom 2f. For example, the partition wall 11k has a conical portion 11q and a connecting portion 11r located between the outer edge of the conical portion 11q when viewed from the axial direction D1 and the first inner surface 11s and the second inner surface 11t.

[0045] Fig. 7 is a rear view of the sharpener 11 as seen from behind. As shown in Figs. 6 and 7, the sharpener 11 has a blade portion 11v that sharpens the stick-shaped cosmetic material M. For example, the sharpener 11 has a plurality of blade portions 11v aligned along the circumferential direction D2 of the cap 2. In this embodiment, the blade portions 11v are formed on the inner surface of the conical portion 11q.

[0046] For example, the multiple blade portions 11v are arranged at equal intervals along the circumferential direction D2 of the cap 2. When the cap 2 is attached to or detached from the container body 3 (middle cylinder 5), the sharpener 11 sharpens the stick-shaped cosmetic material M while rotating in the circumferential direction D2 relative to the cap 2. More specifically, the multiple blade portions 11v sharpen the stick-shaped cosmetic material M when the sharpener 11 rotates in the circumferential direction D2 relative to the cap 2.

[0047] The blade portion 11v has a blade 11w facing one side in the circumferential direction D2. When the sharpener 11 rotates relative to the cap 2, the blade 11w enters the stick-shaped cosmetic material M in the circumferential direction D2, thereby shaving off the stick-shaped cosmetic material M along the circumferential direction D2. The shaved stick-shaped cosmetic material M is stored inside the cap 2, for example.

[0048] As an example, the sharpener 11 has four blade portions 11v, and when the cap 2 is attached to the container body 3, the sharpener 11 rotates 90 degrees relative to the cap 2. In this case, when the cap 2 is attached, the four blade portions 11v can sharpen the stick-shaped cosmetic material M one full rotation along the circumferential direction D2. However, the sharpener 11 may have two, three, five or more blade portions 11v, and the number of blade portions 11v is not particularly limited. Furthermore, the blade portions 11v may have a blade 11w facing one side of the circumferential direction D2 and a blade facing the other side of the circumferential direction D2. In this case, the stick-shaped cosmetic material M can be more reliably sharpened when the cap 2 is attached or detached.

[0049] 2 and 3, the operation of the sharpener 11 when attaching or detaching the cap 2 to or from the container body 3 will be described. First, when the cap 2 is not attached to the container body 3, the sharpener 11 is biased by the spring 12 inside the cap 2, and the expanded diameter portion 11b of the sharpener 11 abuts against the protrusion 2j of the cap 2.

[0050] Before the cap 2 is attached, the stick-shaped cosmetic material M is advanced from the container body 3 so that it protrudes from the opening 4b. The more the stick-shaped cosmetic material M protrudes from the opening 4b, the more stick-shaped cosmetic material M can be shaved off. Therefore, the amount of stick-shaped cosmetic material M shaved off can be adjusted by adjusting the amount of the stick-shaped cosmetic material M protruding from the opening 4b.

[0051] When the cap 2 is attached to the container body 3 from which the stick-shaped cosmetic material M protrudes from the opening 4b, the stick-shaped cosmetic material M abuts against the sharpener 11. More specifically, the stick-shaped cosmetic material M enters the conical portion 11q of the sharpener 11, and the sharpener 11 is pressed by the stick-shaped cosmetic material M.

[0052] When the sharpener 11 is pressed by the stick-shaped cosmetic material M, the sharpener 11 is pushed into the bottom portion 2f of the cap 2, and the convex portion 11c of the sharpener 11 moves along the spiral groove 2r of the cap 2. At this time, the sharpener 11 rotates in one direction relative to the cap 2. When the sharpener 11 rotates in one direction relative to the cap 2, the blade portion 11v (edge ​​11w) bites into the stick-shaped cosmetic material M, and the blade portion 11v cuts off the stick-shaped cosmetic material M in the circumferential direction D2. Then, the first concave-convex portion 2c of the cap 2 engages with the second concave-convex portion 5g of the container body 3 (middle cylinder 5), completing the attachment of the cap 2 to the container body 3.

[0053] As described above, when the blade portion 11v has a blade 11w facing one side in the circumferential direction D2 and a blade facing the other side in the circumferential direction D2, the stick-shaped cosmetic material M can be shaved even when the cap 2 is removed from the container body 3. Specifically, when the engagement of the first uneven portion 2c with the second uneven portion 5g is released and the cap 2 is removed from the container body 3, the convex portion 11c of the sharpener 11 moves along the spiral groove 2r of the cap 2, causing the sharpener 11 to rotate in the direction opposite to the one direction described above. When the sharpener 11 rotates in the opposite direction relative to the cap 2, the blade facing the other side in the circumferential direction D2 bites into the stick-shaped cosmetic material M, shaving the stick-shaped cosmetic material M along the circumferential direction D2. In this case, it is possible to shave the stick-shaped cosmetic material M even when the cap 2 is removed from the container body 3.

[0054] Next, the effects obtained from the stick-type cosmetic material dispensing container 1 according to this embodiment will be described. The stick-type cosmetic material dispensing container 1 includes a container body 3, a cap 2, and a sharpener 11, with the sharpener 11 provided inside the cap 2. The cap 2 is detachable from the container body 3, and the sharpener 11 is rotatable in the circumferential direction D2 of the cap 2. When the cap 2 is attached to or detached from the container body 3, the sharpener 11 sharpens the stick-type cosmetic material M while rotating in the circumferential direction D2 of the cap 2. Because the stick-type cosmetic material M is sharpened by the sharpener 11 rotating in the circumferential direction D2 of the cap 2, the stick-type cosmetic material M can be appropriately sharpened along the circumferential direction D2 of the stick-type cosmetic material M. This prevents the stick-type cosmetic material M from being wasted, and prevents the problem of the stick-type cosmetic material M being consumed too quickly. Furthermore, in this embodiment, the stick-type cosmetic material dispensing container 1 does not have a biasing means for biasing the stick-type cosmetic material M toward the sharpener 11. Therefore, the problem of the stick-shaped cosmetic material M being scraped off too much can be more reliably prevented.

[0055] In this embodiment, the cap 2 has a cylindrical shape with a bottom. The stick-shaped cosmetic material dispensing container 1 is provided with a spring 12 that is provided inside the cap 2 and urges the sharpener 11 in the direction opposite the bottom 2f of the cap 2. In this case, the sharpener 11 is urged in the direction opposite the bottom 2f of the cap 2 by the spring 12. Therefore, when the cap 2 is attached to the container body 3, the sharpener 11 is urged toward the stick-shaped cosmetic material M, and the sharpener 11, which rotates in the circumferential direction D2, can sharpen the stick-shaped cosmetic material M more appropriately.

[0056] In this embodiment, the cap 2 has a first uneven portion 2c on its inner surface 2b, and the container body 3 has a second uneven portion 5g provided on the outer surface of the container body 3 that engages with the first uneven portion 2c when the cap 2 is attached to the container body 3. The second uneven portion 5g engages with the first uneven portion 2c when the sharpener 11 is in contact with the stick-type cosmetic material M. In this case, when the cap 2 is attached to the container body 3 and the second uneven portion 5g engages with the first uneven portion 2c, the sharpener 11 is in contact with the stick-type cosmetic material M. Therefore, it is possible to sharpen the stick-type cosmetic material M in the circumferential direction D2 not only when attaching the cap 2 but also when removing the cap 2. This allows the stick-type cosmetic material M to be sharpened more reliably and appropriately.

[0057] As shown in Fig. 7, in this embodiment, the sharpener 11 has a plurality of blade portions 11v aligned along the circumferential direction D2 of the cap 2. The plurality of blade portions 11v shave the stick-shaped cosmetic material M when the sharpener 11 rotates in the circumferential direction D2 relative to the cap 2. In this case, the plurality of blade portions 11v aligned along the circumferential direction D2 rotate to shave the stick-shaped cosmetic material M, so that the stick-shaped cosmetic material M can be reliably shave even if the amount of rotation of the sharpener 11 relative to the cap 2 is small. Therefore, the mechanism for rotating the sharpener 11 can be simplified.

[0058] The above describes an embodiment of a stick-type cosmetic material dispensing container according to the present disclosure. However, the stick-type cosmetic material dispensing container according to the present disclosure is not limited to the above-described embodiment, and may be modified within the scope of the gist described in the claims. In other words, the structure, shape, size, material, number, and arrangement of each part of the stick-type cosmetic material dispensing container may be modified as appropriate within the scope of the above-described gist.

[0059] For example, in the above-described embodiment, the cap 2 has a tubular portion 2d and a bottom portion 2f. In the cap 2, the bottom portion 2f may be detachable from the tubular portion 2d. In this case, with the bottom portion 2f removed from the tubular portion 2d, scraps of the stick-shaped cosmetic material M sharpened by the sharpener 11 can be removed from the cap 2. Furthermore, the cap 2 does not have to have a bottom portion 2f. In this case, a catch portion consisting of a protrusion, a step, or the like may be provided on the inner surface of the placement area 2k of the cap 2, and the spring 12 may be disposed between the catch portion and the sharpener 11.

[0060] For example, a stick-type cosmetic material dispensing container may have some replaceable parts. That is, it may be refillable. For example, a cartridge composed of the cap 2, front tube 4, middle tube 5, female screw member 7, movable body 8, spring 9, O-ring 10, sharpener 11, and spring 12 may be detachably attached to the rear tube 6. In this case, a cartridge that has run out of stick-type cosmetic material M can be removed from the rear tube 6, and a new cartridge containing stick-type cosmetic material M can be attached to the rear tube 6. This cartridge may not have the cap 2, sharpener 11, or spring 12, and may be composed only of the front tube 4, middle tube 5, female screw member 7, movable body 8, spring 9, and O-ring 10. In this way, the types of parts that make up the cartridge can be changed as needed.

[0061] In the above-described embodiment, a rod-shaped cosmetic dispensing container 1 has been described, which includes a female screw member 7 having a female screw 7f and a movable body 8 having a male screw 8d, and which functions to dispense a rod-shaped cosmetic material M through the relative rotation of the female screw member 7 and the movable body 8, which activates the screwing action between the female screw 7f and the male screw 8d. However, a rod-shaped cosmetic dispensing container may not include the female screw member 7 and the movable body 8. A rod-shaped cosmetic dispensing container does not have to dispense a rod-shaped cosmetic material by relative rotation. Instead of relative rotation, a rod-shaped cosmetic dispensing container may have a dispensing mechanism that is a mechanical extrusion mechanism, such as a knock-type mechanism, and may extrude the rod-shaped cosmetic material by the dispensing mechanism, or may be equipped with a squeeze-type dispensing mechanism.
