Abstract

To provide a cosmetic container allowing for realizing a size reduction by making it compact and inhibiting a lid from unintentionally falling out of a container body.SOLUTION: A cosmetic container 1 according to one embodiment includes a container body 10 having mountain-like projections 18 and circumferential projections 19, in which respective ones of the mountain-like projection 18 and the circumferential projection 19 protrude from a side face. A lid 20 has a plurality of valley-like projection 25 and engaging projections 26. In a state where the lid 20 is placed on the container body 10, the mountain-like projection 18 enters between one pair of valley-like projections 25 arranged along a circumferential direction D3, and the circumferential projection 19 goes into engagement with one pair of engaging projections 26 in an axial direction D1. When the lid 20 is rotated in the circumferential direction D3 relatively to the container body 10, the valley-like projection 25 runs on the mountain-like projection 18 and the one pair of engaging projections 26 move in the circumferential direction D3 to cancel the engagement of the circumferential projection 19 in the axial direction D1.SELECTED DRAWING: Figure 9

Description

Technical Field

[0001] The present disclosure relates to a cosmetic container including a container body and a lid.

Background Art

[0002] Japanese Patent Application Laid-Open No. 2020-164242 describes a container with a lid as a cosmetic container. The container with a lid includes a container body having a cylindrical mouth portion and a lid covering the mouth portion of the container body. A plurality of guide portions each including a horizontal ridge portion and an inclined groove portion are provided at predetermined intervals in the circumferential direction on the lower outer peripheral surface of the mouth portion of the container body. The inclined groove portion has a substantially V-shaped cross section in a front view. The horizontal ridge portion has a horizontal plane extending horizontally so as to connect the upper ends of a pair of inclined groove portions. A locking protrusion is provided on the outer peripheral surface of the horizontal ridge portion. The locking protrusion extends horizontally in the circumferential direction with a predetermined length.

[0003] On the inner peripheral surface of the lower end portion of the lid, a plurality of locking recesses that are detachably locked to the locking protrusions of the container body are provided at predetermined intervals in the circumferential direction. The locking recesses are arranged at corresponding positions in the circumferential direction of the locking protrusions. The locking recesses are formed such that both ends in the circumferential direction thereof are tapered, and the depth gradually increases from there toward the central portion side.

[0004] When the locking protrusion of the container body is located on the central side of the locking recess of the lid, the locking of the lid to the container body becomes strong. When the lid rotates in the circumferential direction with respect to the container body, the locking protrusion moves to one end side or the other end side in the circumferential direction where the locking recess becomes shallower, and the locking of the lid to the container body becomes weak. Then, the protruding portion formed on the inner surface of the lid rides on the inclined groove portion of the guide portion of the container body, the lid is lifted, and the lid is removed from the container body.

Summary of the Invention

[0006] In the aforementioned lidded container, the container body has a guide portion with a horizontal ridge protruding from the lower outer surface of the opening, and a locking projection protruding from the horizontal ridge. Thus, the horizontal ridge protrudes from the outer surface of the container body, and the locking projection further protrudes from the horizontal ridge. Therefore, the diameter of the container body is increased by the horizontal ridge and the locking projection, so there is room for improvement in terms of making the container body more compact.

[0007] Furthermore, in the aforementioned container with a lid, when the lid rotates circumferentially relative to the container body, the locking mechanism of the lid to the container body weakens, resulting in the lid coming off the container body. However, in this container with a lid, since one locking projection on the container body engages with one locking recess on the lid, a problem arises where the lid can easily come off in the axial direction of the container body. Therefore, there is a possibility that the lid may fall off unintentionally.

[0008] This disclosure aims to provide a cosmetic container that can be made compact and miniaturized, while also preventing the lid from unintentionally falling off the container body. [Means for solving the problem]

[0009] The cosmetic container according to this disclosure comprises a cylindrical container body having an opening and a lid attached to the side of the container body. The container body has mountain-shaped projections formed on its side surface, which appear mountain-shaped in a side view, and circumferential projections located on both sides of the container body in the circumferential direction relative to the top of the mountain-shaped projection located on the opening side. Each of the mountain-shaped projections and circumferential projections protrudes from the side surface. The lid has an inner surface that faces the side surface of the container body when attached to the container body, a plurality of valley-shaped projections protruding from the inner surface and appearing valley-shaped in a side view, and engaging projections protruding from each valley-shaped projection. When the lid is attached to the container body, the mountain-shaped projections fit between pairs of valley-shaped projections arranged along the circumferential direction, and the circumferential projections engage with pairs of engaging projections located on each side of the circumferential direction of the circumferential projections in the axial direction of the container body. When the lid is rotated circumferentially relative to the container body while it is attached, the valley-shaped projection rides up onto the mountain-shaped projection, and the pair of engaging projections move circumferentially relative to the circumferential projection, releasing the axial engagement of one of the pair of engaging projections with the circumferential projection.

[0010] In this cosmetic container, the container body has mountain-shaped protrusions formed on its side surface and circumferential protrusions located on both sides of the top of the mountain-shaped protrusions in the circumferential direction, with both the mountain-shaped protrusions and the circumferential protrusions protruding from the respective side surfaces. Therefore, the mountain-shaped protrusions and the circumferential protrusions protrude from the same surface. As a result, the outer diameter of the container body can be reduced, making the container body more compact. The lid has valley-shaped protrusions protruding from its inner surface and engaging protrusions protruding from the valley-shaped protrusions. When the lid is attached to the container body, the circumferential protrusions of the container body engage axially with a pair of engaging protrusions on the lid located on both sides in the circumferential direction. Therefore, since the pair of engaging protrusions on the lid engage with each of the circumferential protrusions of the container body in the circumferential direction, it becomes difficult to remove the lid from the container body in the axial direction. As a result, it becomes difficult to remove the lid axially from the container body, thus preventing the lid from falling off unintentionally. Furthermore, when the lid is rotated circumferentially relative to the container body, the engagement with one of the pair of engaging protrusions is released, allowing the lid to be easily removed from the container body. Therefore, the lid can be easily removed from the container body by rotating the lid relative to the container body.

[0011] The height of the circumferential projections on the sides may be lower than the height of the mountain-shaped projections on the sides. In this case, since the height of the circumferential projections that engage with the engaging projections of the lid is lower than that of the mountain-shaped projections, the enlargement of the diameter of the container body can be suppressed more reliably. Therefore, this contributes to further compacting of the container body. [Effects of the Invention]

[0012] According to this disclosure, it is possible to make the container more compact and smaller, and to prevent the lid from unintentionally falling off the container body. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0014] Hereinafter, embodiments of the cosmetic 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 denoted by the same reference numerals, and redundant descriptions are omitted as appropriate. Also, the drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and dimensional ratios and the like are not limited to those shown in the drawings.

[0015] FIG. 1 is a side view of a cosmetic container 1 according to an embodiment. FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1. As shown in FIGS. 1 and 2, the cosmetic container 1 includes a cylindrical container body 10 and a lid 20 that covers an opening 10b formed at one end (upper end) in the axial direction D1 in which the axis L of the container body 10 extends.

[0016] For example, the container body 10 has a cylindrical shape, and the lid 20 has a hemispherical shape. The container body 10 holds an application body M having a cosmetic, and the lid 20 is attached to the container body 10 so as to cover the application body M. For example, a powder cosmetic is supplied to the application body M. As an example, the powder cosmetic is a cheek or loose powder, but is not particularly limited. The cosmetic container 1 is, for example, a container constituting a puff cheek.

[0017] FIG. 3 is a plan view showing the container body 10. The container body 10 is made of, for example, PP (polypropylene). As shown in FIGS. 2 and 3, for example, the cosmetic container 1 includes an O-ring 30, and the container body 10 has an annular recess 10c into which the O-ring 30 fits. The container body 10 has a cylindrical application body holding portion 11 that holds the application body M, and a cylindrical exposed portion 12 located outside the application body holding portion 11 in the radial direction D2.

[0018] For example, the end portion 12b of the exposed portion 12 on the side of the application body holding portion 11 is rounded. The container body 10 has a connecting portion 16 that connects the application body holding portion 11 and the exposed portion 12 to each other. In the connecting portion 16, the application body holding portion 11 and the exposed portion 12 are connected to each other such that the application body holding portion 11 and the exposed portion 12 are arranged along the radial direction D2.

[0019] The application body holding portion 11 has a first cylindrical portion 13 that is exposed when the lid 20 is removed, a bottomed cylindrical second cylindrical portion 14 located inside the exposed portion 12 in the radial direction D2, and a base portion 15 on which the application body M is placed. The container body 10 has a recess 17 that is recessed in the axial direction D1 between the exposed portion 12 and the second cylindrical portion 14. The bottom surface of the recess 17 is the connecting portion 16.

[0020] FIG. 4 is a cross-sectional view taken along the line B-B of FIG. 3. As shown in FIGS. 3 and 4, the base portion 15 has a coating material placement portion 15b that extends from the inner surface 13b of the first cylindrical portion 13 to the inside in the radial direction D2 of the first cylindrical portion 13, and a rib portion 15c that extends from the coating material placement portion 15b to the bottom surface 14b of the second cylindrical portion 14.

[0021] For example, the coating material mounting section 15b has a plate-like shape with the axial direction D1 being the thickness direction. The base section 15 has multiple coating material mounting sections 15b, and when viewed along the axial direction D1, the multiple coating material mounting sections 15b are arranged radially. When viewed along the axial direction D1, the coating material mounting section 15b has a trapezoidal shape with rounded corners. The length (width) of the coating material mounting section 15b in the circumferential direction D3 decreases as it moves inward in the radial direction D2.

[0022] The rib portion 15c is provided to support the coating material mounting portion 15b. For example, the base portion 15 has multiple rib portions 15c, and each rib portion 15c is provided corresponding to the coating material mounting portion 15b. The rib portion 15c protrudes inward from the inner surface 13b in the radial direction D2 of the first cylindrical portion 13. The rib portion 15c has a plate-like shape with the circumferential direction D3 as the plate thickness direction. In a cross-section of the container body 10 cut along a plane perpendicular to the axial direction D1 and the radial direction D2, the rib portion 15c has a trapezoidal shape. In this cross-section, the length (width) of the rib portion 15c in the radial direction D2 decreases from the coating material mounting portion 15b toward the bottom surface 14b.

[0023] The second cylindrical portion 14 has a side portion 14c located inside the radial direction D2 of the exposed portion 12, and a bottom portion 14d including a bottom surface 14b. For example, the bottom portion 14d has a plate-like shape with the axial direction D1 being the thickness direction. A recess 14h is formed on the outer surface 14g (bottom surface) of the bottom portion 14d. For example, the inner surface of the recess 14h is spherical. For example, the bottom portion 14d has a plurality of recesses 14h.

[0024] The bottom portion 14d has a through hole 14f that penetrates the bottom portion 14d in the axial direction D1. The number of through holes 14f may be one or more. For example, the through hole 14f is formed in the center of the bottom portion 14d when viewed along the axial direction D1. The cosmetic flows into and fills the coating body M through the through hole 14f and the base portion 15, on the inside of the exposed portion 12 in the radial direction D2.

[0025] The first cylindrical portion 13 has a stepped cylindrical shape that protrudes in the radial direction D2 and is recessed in the radial direction D2. Figure 5 is a side view showing the container body 10 including the first cylindrical portion 13. As shown in Figure 5, the first cylindrical portion 13 has a first side portion 13c in which the aforementioned annular recess 10c is formed, and a second side portion 13d located on the opposite side from the exposed portion 12 when viewed from the first side portion 13c.

[0026] The first side portion 13c has a first outer surface 13f extending axially D1 from the exposed portion 12, an annular recess 10c, a second outer surface 13g located on the opposite side from the first outer surface 13f when viewed from the annular recess 10c, and a tapered surface 13h extending from the second outer surface 13g to the second side portion 13d such that the diameter of the first cylindrical portion 13 decreases. The annular recess 10c is located between the first outer surface 13f and the second outer surface 13g.

[0027] The outer diameters of the first outer surface 13f and the second outer surface 13g are, for example, the same. Also, the outer diameters of the first outer surface 13f and the second outer surface 13g are greater than the maximum value of the outer diameter of the second side portion 13d. That is, the maximum value of the outer diameter of the first side portion 13c is greater than the maximum value of the outer diameter of the second side portion 13d.

[0028] The second side portion 13d has a side surface 13j, a first tapered surface 13k located on the opposite side from the first side portion 13c when viewed from the side surface 13j, and a second tapered surface 13m that constitutes the end of the first cylindrical portion 13 in the axial direction D1. The side surface 13j, the first tapered surface 13k, and the second tapered surface 13m are arranged in this order along the axial direction D1.

[0029] The first tapered surface 13k extends from the side surface 13j such that the outer diameter of the first cylindrical portion 13 decreases, and the second tapered surface 13m extends from the first tapered surface 13k such that the outer diameter of the first cylindrical portion 13 decreases. The inclination angle of the second tapered surface 13m with respect to the axial direction D1 is greater than the inclination angle of the first tapered surface 13k with respect to the axial direction D1. The first cylindrical portion 13 may have a rounded curved surface instead of the first tapered surface 13k and the second tapered surface 13m.

[0030] A cover 20 is attached to the side surface 13j. The side surface 13j has a mountain-shaped projection 18 that appears mountain-shaped when viewed from the side (from a direction intersecting the axial direction D1), and circumferential projections 19 located on both sides in the circumferential direction D3 relative to the top 18b of the mountain-shaped projection 18 located on the opening 10b side. Both the top 18b and the circumferential projections 19 protrude from the side surface 13j.

[0031] For example, the mountain-shaped projection 18 has an isosceles triangular shape. The angle of the hypotenuse 18d of the mountain-shaped projection 18 with respect to the circumferential direction D3 is, for example, 30° or more and 45° or less. For example, the angle of the apex 18b is 90° or more and 135° or less. The container body 10 has, for example, a plurality of mountain-shaped projections 18.

[0032] Multiple mountain-shaped protrusions 18 are arranged along the circumferential direction D3. For example, the container body 10 has four mountain-shaped protrusions 18. The length of the mountain-shaped protrusions 18 in the circumferential direction D3 decreases as it approaches the opening 10b. Each mountain-shaped protrusion 18 has a top portion 18b and a base portion 18c provided adjacent to the first side portion 13c (tapered surface 13h). For example, the top portion 18b is rounded.

[0033] For example, the height of the circumferential projection 19 relative to the side surface 13j is lower than the height of the mountain-shaped projection 18 relative to the side surface 13j. For example, the circumferential projection 19 has an extended portion 19b that extends in the circumferential direction D3 from the top 18b of the mountain-shaped projection 18, and an end portion 19c located on the opposite side of the top 18b of the extended portion 19b.

[0034] The container body 10 has, for example, a plurality of circumferential protrusions 19, which are arranged along the circumferential direction D3. The circumferential protrusions 19 are provided in correspondence with the mountain-shaped protrusions 18. The circumferential protrusions 19 are connected to the mountain-shaped protrusions 18, and the circumferential protrusions 19 extend from the mountain-shaped protrusions 18 in the circumferential direction D3. At least a portion of the circumferential protrusions 19 are formed at a position closer to the opening 10b (upper side in Figure 5) than the top portion 18b. Alternatively, the circumferential protrusions 19 may be formed at the same position as the top portion 18b. The circumferential protrusions 19 have a pair of extending portions 19b and a pair of end portions 19c, which are arranged along the circumferential direction D3.

[0035] For example, the pair of extensions 19b are formed at positions symmetrical to each other with respect to the apex 18b. The extensions 19b have a rectangular shape in side view. For example, the outer surface of the extension 19b (the surface facing outward in the radial direction D2) is a curved surface. The height of the extension 19b relative to the side surface 13j increases towards the center in the axial direction D1 of the extension 19b. For example, the cross-section when the extension 19b is cut by a plane perpendicular to the axial direction D1 and the radial direction D2 is hemispherical.

[0036] For example, the pair of ends 19c are formed in positions symmetrical to each other with respect to the top 18b. The ends 19c have a semicircular shape in side view. The length of the ends 19c in the axial direction D1 decreases as it moves away from the extension 19b. The height of the ends 19c relative to the side surface 13j decreases as it moves away from the extension 19b.

[0037] Next, the lid 20 will be described. The lid 20 is made of, for example, PCTA (polycyclohexanedimethylene terephthalate). Figure 6 is a cross-sectional view of the lid 20 when it is cut along a plane extending in the axial direction D1 and the radial direction D2. Figure 7 is a perspective view of the lid 20 seen from the opening 20b side. The lid 20 is hollow.

[0038] As shown in Figures 6 and 7, for example, the lid 20 has a cylindrical portion 21 extending in the axial direction D1 and a hemispherical portion 22 located on the opposite side of the opening 20b of the cylindrical portion 21. The hemispherical portion 22 is the part located on the opposite side (for example, the upper side) from the container body 10 when the lid 20 is attached to the container body 10.

[0039] Furthermore, the lid 20 has a first inner surface 23 located inside the cylindrical portion 21 and a second inner surface 24 located inside the hemispherical portion 22. The second inner surface 24 is spherical. When the lid 20 is attached to the container body 10, the second inner surface 24 faces the coated body M. The first inner surface 23 is stepped cylindrical.

[0040] The first inner surface 23 includes a first inclined surface 23b that inclins to widen in diameter from the second inner surface 24, and an inner surface 23c that extends in the axial direction D1 from the end of the first inclined surface 23b opposite to the second inner surface 24. Furthermore, the first inner surface 23 includes a second inclined surface 23d that inclins to widen in diameter from the inner surface 23c, and an extending surface 23f that extends from the second inclined surface 23d to the opening 20b.

[0041] The lid 20 has, for example, a stepped portion 23g located between the first inclined surface 23b and the inner surface 23c. When the lid 20 is attached to the container body 10, the inner surface 23c faces the side surface 13j of the container body 10. When the lid 20 is attached to the container body 10, the second inclined surface 23d faces the tapered surface 13h (see Figure 5) of the container body 10, and the extended surface 23f faces the first outer surface 13f and the second outer surface 13g of the container body 10 and is in close contact with the O-ring 30.

[0042] The inner surface 23c has a plurality of valley-shaped projections 25 that appear valley-shaped in a side view, and engaging projections 26 that protrude from the valley-shaped projections 25. The valley-shaped projections 25 extend from the first inclined surface 23b toward the opening 20b, and the length of the valley-shaped projections 25 in the circumferential direction D3 becomes shorter as it approaches the opening 20b. The valley-shaped projections 25 have a top portion 25b located on the opening 20b side and a base portion 25c provided adjacent to the first inclined surface 23b. For example, the top portion 25b is rounded.

[0043] Multiple valley-shaped protrusions 25 are arranged along the circumferential direction D3. The inclination angle of the hypotenuse 25d of the valley-shaped protrusions 25 with respect to the circumferential direction D3 is, for example, 30° or more and 45° or less. As an example, the hypotenuse 25d of the valley-shaped protrusions 25 is rounded. Between a pair of valley-shaped protrusions 25 arranged along the circumferential direction D3, a mountain-shaped recess 27 is formed into which the mountain-shaped protrusions 18 of the container body 10 fit. For example, the number of valley-shaped protrusions 25 is twice the number of mountain-shaped protrusions 18. As an example, the number of valley-shaped protrusions 25 is 8.

[0044] The engaging projection 26 engages with the circumferential projection 19 of the container body 10 in the axial direction D1. This engagement will be described in detail later. The engaging projection 26 corresponds to the portion that protrudes from the valley-shaped projection 25 and extends in the circumferential direction D3 on the valley-shaped projection 25. For example, when the engaging projection 26 is cut by a plane perpendicular to the axial direction D1 and the radial direction D2, the cross-section is trapezoidal. In this case, the engaging projection 26 has a pair of inclined surfaces 26b aligned along the axial direction D1 and a top surface 26c located between the pair of inclined surfaces 26b.

[0045] Next, the movement of each part in attaching the lid 20 to the container body 10 and removing the lid 20 from the container body 10 will be explained with reference to Figures 8(a), 8(b), 9(a), and 9(b). In Figures 8(a), 8(b), 9(a), and 9(b), the inner parts of the lid 20 are shown with solid lines for ease of understanding.

[0046] First, as shown in Figure 8(a), when the lid 20 is attached to the container body 10, the hypotenuse 25d of the valley-shaped projection 25 on the lid 20 contacts the hypotenuse 18d of the mountain-shaped projection 18 on the container body 10, adjusting the position of the lid 20 relative to the container body 10. At the same time, the circumferential projection 19 crosses over the pair of engaging projections 26 in the axial direction D1, and the circumferential projection 19 engages with the pair of engaging projections 26 in the axial direction D1. At this time, the mountain-shaped projection 18 is positioned between the pair of valley-shaped projections 25. In other words, with the lid 20 attached to the container body 10, the mountain-shaped projection 18 is positioned between the pair of valley-shaped projections 25, and the circumferential projection 19 engages with the pair of engaging projections 26 in the axial direction D1.

[0047] Then, in order to remove the lid 20 from the container body 10, if the lid 20 is pulled axially in the direction D1 relative to the container body 10, as shown in Figure 8(b), the circumferential projection 19 engages with the pair of engaging projections 26 in the direction D1, making it difficult to remove the lid 20. However, if the lid 20 is pulled axially in the direction D1 with a force greater than a certain strength, the pair of engaging projections 26 will overcome the circumferential projection 19 in the direction D1, making it possible to remove the lid 20.

[0048] When the lid 20 is rotated circumferentially D3 relative to the container body 10 in order to remove the lid 20 from the container body 10, as shown in Figure 9(a), the hypotenuse 25d of the valley-shaped projection 25 of the lid 20 moves axially D1 along the hypotenuse 18d of the mountain-shaped projection 18 of the container body 10, and the engagement force between one of the engaging projections 26 (referred to as engaging projection 26A in Figures 9(a) and 9(b)) and the circumferential projection 19 weakens.

[0049] Then, as shown in Figure 9(b), the valley-shaped projection 25 rises above the mountain-shaped projection 18, and the pair of engaging projections 26 move circumferentially D3 relative to the circumferential projection 19, releasing the engagement of the circumferential projection 19 with the pair of engaging projections 26. In this state, the lid 20 can be easily removed from the container body 10 by pulling it up. The lid 20 can also be easily removed from the container body 10 by rotating it in one direction (for example, clockwise in a plan view) or in the opposite direction (for example, counterclockwise in a plan view).

[0050] Next, the effects and advantages obtained from the cosmetic container 1 according to this embodiment will be described in detail. As shown in Figure 5, the cosmetic container 1 has a mountain-shaped projection 18 formed on the side surface 13j and circumferential projections 19 located on both sides in the circumferential direction D3 relative to the top 18b of the mountain-shaped projection 18, with the mountain-shaped projection 18 and the circumferential projections 19 each protruding from the side surface 13j. Therefore, the mountain-shaped projection 18 and the circumferential projections 19 protrude from the same plane. Thus, the outer diameter of the container body 10 can be reduced, and the container body 10 can be made more compact.

[0051] As shown in Figures 8(a), 8(b), 9(a), and 9(b), the lid 20 has a valley-shaped projection 25 protruding from the inner surface 23c and an engaging projection 26 protruding from the valley-shaped projection 25. When the lid 20 is attached to the container body 10, the circumferential projection 19 of the container body 10 engages in the axial direction D1 with a pair of engaging projections 26 of the lid 20 located on both sides in the circumferential direction D3. Therefore, since the pair of engaging projections 26 of the lid 20 engage with each side of the circumferential projection 19 of the container body 10 in the circumferential direction D3, it is difficult to remove the lid 20 from the container body 10 in the axial direction D1. Thus, it is difficult to remove the lid 20 from the container body 10 in the axial direction D1, and the unintended detachment of the lid 20 can be suppressed.

[0052] Furthermore, when the lid 20 is rotated circumferentially D3 relative to the container body 10, the engagement of one of the pair of engaging protrusions 26 (engaging protrusion 26A) with the circumferential protrusion 19 is released, allowing the lid 20 to be easily removed from the container body 10. Therefore, the lid 20 can be easily removed from the container body 10 by rotating the lid 20 relative to the container body 10.

[0053] As shown in Figure 5, in this embodiment, the height of the circumferential projection 19 relative to the side surface 13j is lower than the height of the mountain-shaped projection 18 relative to the side surface 13j. Therefore, because the height of the circumferential projection 19 that engages with the engaging projection 26 of the lid 20 is lower than that of the mountain-shaped projection 18, the enlargement of the diameter of the container body 10 can be suppressed more reliably. Thus, this contributes to further miniaturization of the container body 10.

[0054] Next, the container body 40 relating to the first modified example will be described with reference to Figure 10. Some of the components of the container body 40 are the same as some of the components of the container body 10 described above. Therefore, in the following, the description of parts that overlap with the container body 10 will be appropriately omitted and the same reference numerals will be used. The container body 40 has circumferential protrusions 49 that have a different shape from the circumferential protrusions 19.

[0055] The circumferential projection 49 has a first extension portion 49b extending in the circumferential direction D3 relative to the apex 18b of the mountain-shaped projection 18, a second extension portion 49c extending in the circumferential direction D3 from the hypotenuse 18d of the mountain-shaped projection 18, and an end portion 49d connecting the first extension portion 49b and the second extension portion 49c to each other. The end portion 49d is located on the opposite side of the mountain-shaped projection 18 from each of the first extension portion 49b and the second extension portion 49c. The end portion 49d is inclined with respect to the axial direction D1, for example, inclined to approach the second extension portion 49c and the hypotenuse 18d from the first extension portion 49b.

[0056] When the circumferential projection 49 is cut along a plane perpendicular to the axial direction D1 and the radial direction D2, the cross-section is trapezoidal. For example, the circumferential projection 49 has a first inclined surface 49f and a second inclined surface 49g aligned along the axial direction D1, and a top surface 49h located between the first inclined surface 49f and the second inclined surface 49g. The same effects and advantages as those of the container body 10 described above can be obtained from the container body 40 configured as described above.

[0057] Next, the container body 50 relating to the second modification will be described with reference to Figure 11. The container body 50 has circumferential protrusions 59 that are different from the circumferential protrusions 49. The container body 50 has a pair of circumferential protrusions 59 that are aligned along the circumferential direction D3, and the circumferential protrusions 59 are provided on each side of the circumferential direction D3 relative to the top 18b of the mountain-shaped protrusion 18. The circumferential protrusions, such as these circumferential protrusions 59, may be divided along the circumferential direction D3, and in the case of this container body 50 as well, the same effects and advantages as those of the container body 10 described above can be obtained.

[0058] The embodiments and various modifications of the cosmetic container relating to this disclosure have been described above. However, the cosmetic container relating to this disclosure is not limited to the embodiments described above, and may be modified or used for other purposes within the scope of the gist described in the claims. That is, the configuration, shape, size, material and arrangement of each component constituting the cosmetic container can be appropriately changed within the scope of the gist described above.

[0059] For example, in the embodiment described above, a circumferential projection 19 having an extended portion 19b that is rectangular in shape when viewed from the side, and an end portion 19c that is semicircular in shape when viewed from the side was described. However, the shape of the circumferential projection may be oval, elliptical, circular, or polygonal, such as rectangular or hexagonal, and can be changed as appropriate. For example, in the second modification described above, a container body 50 having two circumferential projections 59 was described. However, the number of circumferential projections in the container body does not have to be two; it may be one or three or more.

[0060] For example, in the above-described embodiment, a cosmetic container 1 was described in which the cosmetic supplied to the applicator M is blush or loose powder, and is a pom-pom blush. However, the cosmetic container according to this disclosure is not limited to pom-pom blush, and may also be a container for eyeshadow or lipstick. Thus, the cosmetic container according to this disclosure is applicable to various containers. [Explanation of symbols]
