Description

Technical Field

[0001] The present invention relates to a cosmetic container. Background Art

[0002] In Patent Document 1, there is described a liquid coating tool capable of drawing multiple lines at once. The liquid coating tool includes a nib unit. The nib unit has: a nib for writing; a relay core for supplying liquid to the rear end portion of the nib; and a sheath provided to cover the outer periphery of a portion of the end portion of the nib other than the tip on the end side.

[0003] An opening is provided at the end of the sheath. The opening of the sheath is divided by one or more partition members to form a plurality of holes. When the nib is assembled into the sheath, the tip on the end side of the nib is branched through the plurality of holes provided in the opening.

[0006] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2023 - 83886 Summary of the Invention

[0007] (Problems to be Solved by the Invention)

[0008] In the above liquid coating tool, when the nib is assembled into the sheath, the nib is inserted through each of the plurality of holes, so that a plurality of thin lines can be drawn through the inserted nib. However, in the above liquid coating tool, after the nib is inserted through each of the plurality of holes, the nib does not move from one hole to another hole.

[0009] As in the above liquid coating tool, if the tip of the end of the coating body is inserted through the plurality of holes in a non-uniform state, it is possible that the tip is unevenly branched. When the tip is not evenly branched into each hole, it is difficult for each of the multiple lines drawn at once to have the same thickness and the same width. As a result, uneven thickness may occur between the multiple lines drawn by the tip. Therefore, it is required to improve the uniformity of the tip at the end.

[0010] An object of the present invention is to provide a cosmetic container capable of improving the uniformity of the tip at the end.

[0011] (Measures for Solving the Problems)

[0012] The cosmetic container (1) according to the present invention includes: a sleeve provided with an opening through which a coating body in the form of a writing brush can be inserted, converging the coating body, and having a cylindrical shape; and a main body engaged with the sleeve. The sleeve has a plurality of protrusions provided on the periphery defining the opening. The plurality of protrusions respectively project in the inner diameter direction of the opening and extend in the axial direction of the sleeve. A gap through which the coating body passes is provided at the front end of each of the plurality of protrusions in the inner diameter direction.

[0013] In this cosmetic container, a space is provided between one protrusion of the plurality of protrusions and a protrusion adjacent to the one protrusion. Since the sleeve has a plurality of protrusions and this space is provided, when the coating body in the form of a writing brush is inserted into the inside of the sleeve, a part of the coating body enters this space. At this time, the coating body branches into a plurality. In this cosmetic container, a gap through which the coating body passes is provided at the front end of each of the plurality of protrusions in the inner diameter direction. Therefore, this space is provided between the plurality of protrusions, and this gap is provided at the front end of the plurality of protrusions in the inner diameter direction. Therefore, even if the tip of the end of the coating body is inserted into this space and this gap in a non-uniform state, the tip can move between this space and this gap. As a result, when the coating body is inserted into the sleeve, even if the amount of the coating body entering one of this space or this gap increases, a part of the coating body will move between this space and this gap. Therefore, even if the tip of the end of the coating body is inserted in a non-uniform state, by the tip moving between this space and this gap, the uniformity of the tip at the end of the coating body can be improved.

[0014] Moreover, the plurality of protrusions respectively extend in the axial direction of the sleeve. Therefore, even if a force is applied to the coating body sandwiched between two adjacent protrusions in the direction in which the two protrusions are arranged, the coating body is not easily bent. Thereby, the usability of the cosmetic container is improved.

[0015] (2) In the above (1), the plurality of protrusions may include a comb-shaped member protruding in the axial direction along the opening. In this case, when the end of the cosmetic container is brought into contact with a hairy part of the body, the comb-shaped member can be easily brought into contact with the skin. When the comb-shaped member protrudes more than the coating body, when the comb-shaped member is brought into contact with the skin, the coating body can be brought into contact with the hairy part of the body and it is difficult for the coating body to be brought into contact with the skin. In this case, it is possible to suppress the attachment of the cosmetic to the skin due to the coating body.

[0016] (3) In the above (1) or (2), the end of the coating body may protrude from the ends of the plurality of protrusions. In this case, by the coating body branched into a plurality protruding from the ends of the plurality of protrusions respectively, the end of the coating body can be brought into contact with a desired part.

[0017] (4) In any one of the above (1) to (3), at the proximal end in the axial direction of each of the plurality of protrusions, the closer to the opening portion, the longer the length in the inner diameter direction of each of the plurality of protrusions can be. When the coating body is inserted into the sleeve and a part of the coating body comes into contact with the plurality of protrusions, a part of the coating body comes into contact with the proximal end portions of each of the plurality of protrusions. According to this structure, the closer the proximal end portion is to the opening portion, the larger the protrusion amount of each of the plurality of protrusions becomes, so that a part of the coating body is smoothly guided in the inner diameter direction. Thereby, when a part of the coating body comes into contact with the plurality of protrusions, bending of a part of the coating body can be suppressed.

[0018] (5) In any one of the above (1) to (4), the sleeve may have a first edge defining the opening portion and a second edge defining the opening portion and located at a position sandwiching the axis of the sleeve together with the first edge. The plurality of protrusions may include a plurality of first protrusions provided on the first edge and a plurality of second protrusions provided on the second edge. Each of the plurality of first protrusions and each of the plurality of second protrusions may face each other. A gap may be provided between each of the plurality of first protrusions and each of the plurality of second protrusions.

[0019] According to this structure, a space is provided between one of the plurality of first protrusions and an adjacent first protrusion. And a space is provided between one of the plurality of second protrusions and an adjacent second protrusion. Therefore, a part of the coating body branches into a coating body on the first edge side entering the space provided between the plurality of first protrusions and a coating body on the second edge side entering the space provided between the plurality of second protrusions. Each first protrusion and each second protrusion face each other, so that the coating body on the first edge side and the coating body on the second edge side are arranged in the inner diameter direction. The tip of the end of the inserted coating body can move between the space provided between the plurality of first protrusions and the space provided between the plurality of second protrusions. As a result, when the coating body is inserted into the sleeve, even if the amount of the coating body on the first edge side or the amount of the coating body on the second edge side becomes larger, a part of the coating body will move between the first edge and the second edge. Therefore, the uniformity of the tip of the end of the coating body in the opposing direction of the first protrusion and the second protrusion can be improved, and thus the uniformity of the tip of the end in the coating body can be further improved.

[0020] (6) In any one of the above (1) to (5), the plurality of protrusions can respectively extend from the opening of the sleeve to the side opposite to the center in the axial direction of the sleeve and further away from the opening. Further, when the coating body is inserted into the sleeve, if the movement of the coating body in the direction crossing the axial direction is not properly restricted by the plurality of protrusions, the advancing direction of some hairs of the coating body may sometimes be inconsistent with that of other hairs. In this case, the alignment state of the coating body may sometimes be disordered. As described above, when the plurality of protrusions respectively extend to the side opposite to the center in the axial direction of the sleeve and further away from the opening, the distance from the end in the axial direction of the sleeve on the side opposite to the side where the opening is located to the plurality of protrusions can be shortened. Thereby, when the coating body is inserted into the sleeve, the coating body can quickly enter between the plurality of protrusions in a state where the alignment state of the coating body is neat inside the sleeve. Therefore, it is possible to suppress the tip of the end of the coating body from entering between the plurality of protrusions in a non-uniform state. As a result, the uniformity of the tip of the end of the coating body can be further improved.

[0050] Hereinafter, embodiments of the cosmetic container according to the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and repeated descriptions are appropriately omitted. In the drawings, for the sake of easy understanding, sometimes a part is simplified or exaggerated for depiction, and the dimensional ratios and the like are not limited to the descriptions in the drawings.

[0051] Figure 1 is a perspective view of the cosmetic container 1. Figure 2 is along Figure 1 a cross-sectional view taken along line II-II. The cosmetic container 1 is used for a user to apply cosmetics at a desired position. The cosmetic container 1 is, for example, an eyebrow pencil. For example, a part of the parts constituting the cosmetic container 1 is cylindrical. Hereinafter, the direction in which the axis of this part of the cosmetic container 1 extends is referred to as the axial direction D1.

[0052] The cosmetic container 1 includes: an outer cylinder member 2, a part that is contacted by the user of the cosmetic container 1; a main body 3, connected to the outer cylinder member 2; a sleeve 4, connected to the main body 3 and having an opening 4a; and an application body 5, protruding from the opening 4a of the sleeve 4.

[0053] In the following description, the direction from the outer cylinder member 2 toward the sleeve 4 in the axial direction D1 is sometimes referred to as "front", "front side" or "front direction", and the direction from the sleeve 4 toward the outer cylinder member 2 in the axial direction D1 is sometimes referred to as "rear", "rear side" or "rear direction". In a cylindrical part, the direction toward the axis or away from the axis in a plane orthogonal to the axis of the part is sometimes referred to as "radial direction". "Radial outer side" means the direction away from the axis in the radial direction, and "radial inner side" means the direction toward the axis in the radial direction.

[0054] The outer cylinder member 2 is, for example, cylindrical. The front end 2a of the outer cylinder member 2 is open. The rear end 2b of the outer cylinder member 2 is closed. An annular recess 2c is provided on the inner peripheral surface of the outer cylinder member 2. The annular recess 2c is provided near the front end 2a. More specifically, the annular recess 2c is provided on the outer cylinder member 2 at a position closer to the front side than the center in the axial direction D1. The annular recess 2c extends, for example, over the entire circumference of the inner peripheral surface of the outer cylinder member 2 around the axis. The annular recess 2c is recessed radially outward of the outer cylinder member 2 on the inner peripheral surface of the outer cylinder member 2. The annular recess 2c has a rear side portion 2d located on the rear side of the annular recess 2c and a front side portion 2e located on the front side of the annular recess 2c. For example, the front side portion 2e is recessed deeper radially outward of the outer cylinder member 2 than the rear side portion 2d.

[0055] The main body 3 has an inner cylinder member 3A that fits into the outer cylinder member 2 and a tail valve 3B connected to the rear end of the inner cylinder member 3A. The inner cylinder member 3A is, for example, cylindrical. The inner cylinder member 3A has an exposed portion 31 on the front side of the inner cylinder member 3A, a non-exposed portion 32 on the rear side of the inner cylinder member 3A, and a flange portion 33 located between the exposed portion 31 and the non-exposed portion 32. The flange portion 33 is annular (e.g., circular). The flange portion 33 projects outward more in the radial direction of the inner cylinder member 3A than the exposed portion 31 and the non-exposed portion 32. For example, the outer diameter of the flange portion 33 is equal to the outer diameter of the outer cylinder member 2. The flange portion 33 contacts the front end 2a of the outer cylinder member 2. In the present embodiment, the front end 2a abuts against the rear end face of the flange portion 33.

[0056] The non-exposed portion 32 is a portion accommodated inside the outer cylinder member 2. The non-exposed portion 32 is cylindrical (e.g., cylindrical). The length of the non-exposed portion 32 in the axial direction D1 is about half of the length of the outer cylinder member 2 in the axial direction D1. An annular projection 32a is provided on the outer peripheral surface of the non-exposed portion 32. The annular projection 32a is provided at the same position as the annular recess 2c in the axial direction D1. The annular projection 32a extends, for example, over the entire circumference of the outer peripheral surface of the non-exposed portion 32 around the axis.

[0057] The annular projection 32a projects radially outward of the non-exposed portion 32 on the outer peripheral surface of the non-exposed portion 32. The annular projection 32a has a rear side portion 32b located on the rear side of the annular projection 32a and a front side portion 32c located on the front side of the annular projection 32a. The front side portion 32c projects more significantly radially outward of the non-exposed portion 32 than the rear side portion 32b. The rear side portion 32b is received in the rear side portion 2d of the annular recess 2c, and the front side portion 32c is received in the front side portion 2e of the annular recess 2c, whereby the annular projection 32a is received in the annular recess 2c. The annular projection 32a is received in the annular recess 2c, whereby the outer cylinder member 2 and the main body 3 are engaged in the axial direction D1.

[0058] The exposed portion 31 is cylindrical. The outer diameter of the exposed portion 31, for example, becomes smaller as it approaches the front end of the exposed portion 31. The outer peripheral surface of the exposed portion 31 has a conical shape. A ring-shaped convex portion 31a is provided on the outer peripheral surface of the exposed portion 31. The ring-shaped convex portion 31a is provided near the flange portion 33. More specifically, the ring-shaped convex portion 31a is provided on the rear side of the center of the exposed portion 31 in the axial direction D1. The ring-shaped convex portion 31a extends, for example, around the axis over the entire circumference of the outer peripheral surface of the exposed portion 31. The ring-shaped convex portion 31a protrudes outward on the outer peripheral surface of the exposed portion 31.

[0059] The cosmetic container 1 includes a lid C that covers a portion of the cosmetic container 1 that is located more forward than the flange portion 33. The outer lid C1 can be attached to and detached from the main body 3 (exposed portion 31). The lid C has an outer lid C1 that forms the outer peripheral surface of the lid C, an inner lid C2 that is accommodated inside the outer lid C1, and a spring C3 that presses the inner lid C2 backward.

[0060] The outer lid C1 is cylindrical (e.g., cylindrical). The front end of the outer lid C1 is closed. The rear end of the outer lid C1 is open. A ring-shaped convex portion C1a is provided on the inner peripheral surface of the outer lid C1. In a state where the lid C is attached to the main body 3, the ring-shaped convex portion C1a is located behind the ring-shaped convex portion 31a. The ring-shaped convex portion C1a extends, for example, around the axis over the entire circumference of the inner peripheral surface of the outer lid C1. The ring-shaped convex portion C1a protrudes inward on the inner peripheral surface of the outer lid C1.

[0061] In a state where the outer lid C1 is not attached to the exposed portion 31, when the outer lid C1 is pushed toward the flange portion 33, the ring-shaped convex portion C1a passes behind the outside of the ring-shaped convex portion 31a. Thereby, the outer lid C1 is attached to the exposed portion 31. At this time, the ring-shaped convex portion C1a comes into contact with the rear side of the ring-shaped convex portion 31a, and thereby the outer lid C1 and the main body 3 are engaged in the axial direction D1.

[0062] In a state where the outer lid C1 is attached to the exposed portion 31, when a forward force is applied to the outer lid C1, the ring-shaped convex portion C1a passes in front of the outside of the ring-shaped convex portion 31a. Thereby, the outer lid C1 is detached from the main body 3.

[0063] The inner lid C2 has a cylindrical main body portion C2a and a protruding portion C2b that protrudes forward from the main body portion C2a. The main body portion C2a is, for example, cylindrical. A ring-shaped convex portion C2c is provided on the outer peripheral surface of the main body portion C2a. The ring-shaped convex portion C2c protrudes from the outer peripheral surface of the main body portion C2a. A ring-shaped convex portion C1b is provided on the inner peripheral surface of the outer lid C1. The ring-shaped convex portion C1b protrudes from the inner peripheral surface of the outer lid C1. The ring-shaped convex portion C1b is located further forward than the ring-shaped convex portion C1a. The ring-shaped convex portion C2c contacts the inner peripheral surface of the outer lid C1, and the ring-shaped convex portion C1b contacts the outer peripheral surface of the main body portion C2a. As a result, a frictional force acts between the inner lid C2 and the outer lid C1. Therefore, it is difficult for the inner lid C2 to move relative to the outer lid C1 in the axial direction D1.

[0064] The protruding portion C2b extends forward from the front end of the main body portion C2a. The protruding portion C2b is cylindrical. The outer diameter of the protruding portion C2b is smaller than the outer diameter of the main body portion C2a. The spring C3 is a helical spring (compression helical spring). The protruding portion C2b passes through the spring C3. The length of the protruding portion C2b in the axial direction D1 is shorter than the natural length of the spring C3. One end of the spring C3 contacts the front end (bottom) of the outer lid C1. The other end of the spring C3 contacts the front end of the main body portion C2a.

[0065] In a state where the outer lid C1 is attached to the exposed portion 31, the inner lid C2 contacts the exposed portion 31. A contact portion C2d is provided on the inner peripheral surface of the inner lid C2. The inner diameter of the contact portion C2d, for example, decreases as it approaches the front end of the inner lid C2 (see Figure 3 ). The contact portion C2d has a rounded corner. More specifically, the contact portion C2d has a rounded corner such that the amount of decrease in the inner diameter of the contact portion C2d becomes smaller as it approaches the front end of the inner lid C2. For example, when the contact portion C2d contacts the exposed portion 31, the spring C3 is in a contracted state. At this time, the spring C3 applies a force to the inner lid C2 in the rearward direction, and thus the inner lid C2 is pressed against the exposed portion 31. As a result, the airtightness inside the inner lid C2 is improved.

[0066] The tail valve 3B is connected to the rear end of the non-exposed portion 32. The tail valve 3B blocks the rear end of the non-exposed portion 32. The tail valve 3B has a bottomed cylindrical shape (for example, a bottomed cylindrical shape). The tail valve 3B has a rear end portion 3Ba located at the rear end of the tail valve 3B and a cylindrical portion 3Bb located in front of the rear end portion 3Ba. The rear end portion 3Ba has a disc shape. For example, the outer diameter of the rear end portion 3Ba is equal to the outer diameter of the non-exposed portion 32. The outer diameter of the rear end portion 3Ba is larger than the outer diameter of the cylindrical portion 3Bb. A plurality of annular protrusions are provided on the outer peripheral surface of the cylindrical portion 3Bb. The annular protrusions protrude from the outer peripheral surface of the cylindrical portion 3Bb. On the inner peripheral surface of the non-exposed portion 32, a plurality of annular recesses are provided at positions that are the same as the respective positions of the plurality of annular protrusions in the axial direction D1. The plurality of annular protrusions provided on the outer peripheral surface of the cylindrical portion 3Bb are received in the plurality of annular recesses provided on the inner peripheral surface of the non-exposed portion 32, whereby the tail valve 3B is engaged with the non-exposed portion 32 in the axial direction D1. The tail valve 3B blocks the rear end of the non-exposed portion 32, so that the cosmetic product does not leak from the rear end of the non-exposed portion 32.

[0067] The cosmetic container 1 includes a cosmetic product accommodating portion 6 provided inside the non-exposed portion 32, a relay core 7 inserted into the cosmetic product accommodating portion 6, and a corrugated tube member 8 surrounding the relay core 7 around the axis. The cosmetic product accommodating portion 6 is provided at the rear side of the non-exposed portion 32. The cosmetic product accommodating portion 6 is a space divided into a cylindrical shape. The rear side portion of the cosmetic product accommodating portion 6 is divided by the tail valve 3B. The corrugated tube member 8 is provided at the front side portion of the cosmetic product accommodating portion 6. At least a part of the cosmetic product accommodating portion 6 is divided by the non-exposed portion 32 in the radial direction. Cosmetic products are accommodated in the cosmetic product accommodating portion 6. As the cosmetic product, for example, a liquid cosmetic product can be cited.

[0068] The relay core 7 extends in the axial direction D1. The relay core 7 is disposed inside the main body 3 such that the front end of the relay core 7 protrudes from the main body 3. The rear end of the relay core 7 is inserted into the cosmetic product accommodating portion 6. The front end of the relay core 7 is located inside the sleeve 4. The front end of the relay core 7 enters the coating body 5. The relay core 7 sends out the cosmetic product accommodated in the cosmetic product accommodating portion 6 to the coating body 5. The relay core 7 is made of, for example, an acrylic resin.

[0069] The corrugated tube member 8 is a member for controlling the flow of the cosmetic product. The corrugated tube member 8 has a groove containing the cosmetic product. The corrugated tube member 8 has a cylindrical shape. The relay core 7 is accommodated in the cylindrical portion of the corrugated tube member 8. The corrugated tube member 8 has a rear end portion 8a having an annular shape (a circular shape as an example). The rear end portion 8a is fitted into a recess 32d formed on the inner peripheral surface of the non-exposed portion 32, whereby the corrugated tube member 8 is attached to the non-exposed portion 32. A cosmetic product accommodating portion 6 is formed between the rear end portion 8a of the corrugated tube member 8 provided inside the non-exposed portion 32 and the tail valve 3B.

[0070] Reference Figure 3, the sleeve 4 will be described in detail. Figure 3 is Figure 2 A partial enlarged view of the sleeve 4 and the peripheral portion of the sleeve 4. The sleeve 4 is cylindrical. The sleeve 4 has an insertion portion 41 inserted into the inside of the exposed portion 31, and a tapered portion 42 extending forward from the insertion portion 41. The insertion portion 41 is cylindrical. An annular convex portion 41a is provided on the outer peripheral surface of the insertion portion 41. The annular convex portion 41a projects from the outer peripheral surface of the insertion portion 41. The annular convex portion 41a extends, for example, over the entire circumference of the outer peripheral surface of the insertion portion 41 around the axis.

[0071] An annular convex portion 31b is provided on the inner peripheral surface of the exposed portion 31. The annular convex portion 31b projects, for example, from the inner peripheral surface of the exposed portion 31. The annular convex portion 31b extends, for example, over the entire circumference of the inner peripheral surface of the exposed portion 31 around the axis. The annular convex portion 41a extends rearward beyond the annular convex portion 31b, whereby the main body 3 is engaged with the sleeve 4 in the axial direction D1. The sleeve 4 has a rear end 4m as an end portion in the axial direction D1 opposite to the side where the opening 4a is located (see Figure 5 ). The rear end 4m is located at the rear end of the insertion portion 41. An opening 4b is provided at the rear end 4m located at the rear end of the insertion portion 41. The coating body 5 can be inserted through the opening 4b. A gap is provided between the rear end 4m of the sleeve 4 (insertion portion 41) and the front end of the corrugated pipe member 8.

[0072] The tapered portion 42 is cylindrical. The outer diameter of the tapered portion 42 becomes smaller as it approaches the front end of the sleeve 4. The outer diameter of the tapered portion 42 at the rear end of the tapered portion 42 is larger than the outer diameter of the insertion portion 41 at the front end of the insertion portion 41. A step is formed at the front end of the insertion portion 41 that expands in diameter toward the rear end of the tapered portion 42. The rear end face of the tapered portion 42 contacts the front end of the exposed portion 31. For example, the outer peripheral surface of the tapered portion 42 extends along the outer peripheral surface of the exposed portion 31. The aforementioned opening 4a of the sleeve 4 is provided at the front end of the tapered portion 42. The coating body 5 can be inserted through the opening 4a. The opening 4a has a rounded rectangular shape when viewed in the axial direction D1 (see Figure 4 ).

[0073] The coating body 5 is inserted through the sleeve 4. More specifically, the coating body 5 is inserted through the inside of the insertion portion 41 and the inside of the tapered portion 42 from the opening 4b and reaches a position further forward than the opening 4a. The sleeve 4 converges the coating body 5 in a state where the coating body 5 is inserted through the inside of the sleeve 4. The sleeve 4 has a plurality of protrusions 43. The detailed structure of the protrusions 43 will be described later.

[0074] The coating body 5 is a writing brush. The coating body 5 has: a rear end portion 51 located between the rear end of the insertion portion 41 and the front end of the corrugated tube member 8; a covering portion 52 located between the relay core 7 and the inner peripheral surface of the insertion portion 41; a converging portion 53 located in front of the covering portion 52; and a plurality of branched hairs 54 located in front of the converging portion 53. The rear end portion 51 is the portion where the hairs forming the coating body 5 are solidified. The covering portion 52 is configured to surround the relay core 7. The covering portion 52 is annular when viewed in the axial direction D1. The covering portion 52 covers the relay core 7. That is, the relay core 7 enters into the coating body 5.

[0075] The converging portion 53 is disc-shaped when viewed in the axial direction D1. The relay core 7 does not enter into the converging portion 53. The branched hairs 54 are the portions where a plurality of hair branches converge at the converging portion 53. The branched hairs 54 form the front end of the coating body 5. Since the cosmetic container 1 has a plurality of branched hairs 54, a plurality of lines can be drawn at once when using the cosmetic container 1.

[0076] Reference Figures 4 to 6 , the protrusion 43 of the sleeve 4 will be described in detail. Figure 4 is the front view of the cosmetic container 1 with the lid C removed. Figure 5 is the cross-sectional view of the sleeve 4 taken along the axis of the sleeve 4. Figure 6 is another cross-sectional view of the sleeve 4 taken along the axis of the sleeve 4. A plurality of protrusions 43 are provided on the periphery defining the opening 4a. The opening 4a is defined by a first edge 4c, a second edge 4d, a third edge 4e, and a fourth edge 4f.

[0077] The first edge 4c extends along the long side direction of the opening 4a when viewed from the front. When viewed from the front, the second edge 4d extends along the long side direction of the opening 4a and is opposed to the first edge 4c along the short side direction of the opening 4a. When viewed from the front, the third edge 4e extends along the short side direction of the opening 4a. The third edge 4e connects one end of the first edge 4c to one end of the second edge 4d. When viewed from the front, the fourth edge 4f extends along the short side direction of the opening 4a. The fourth edge 4f connects the other end of the first edge 4c to the other end of the second edge 4d. The plurality of protrusions 43 include a plurality of first protrusions 431 provided on the first edge 4c and a plurality of second protrusions 432 provided on the second edge 4d. The sleeve 4 has a pair of side walls 44 including the third edge 4e or the fourth edge 4f.

[0078] A plurality of protrusions 43 respectively protrude in the inner diameter direction D2 of the opening 4a. In the present embodiment, the "inner diameter direction D2" refers to the short side direction of the opening 4a, including the direction from the first edge 4c toward the imaginary line X extending along the long side direction of the opening 4a at the middle between the first edge 4c and the second edge 4d, and the direction from the second edge 4d toward the imaginary line X. The first protrusion 431 protrudes in the inner diameter direction D2 of the opening 4a by protruding from the first edge 4c toward the imaginary line X. The second protrusion 432 protrudes in the inner diameter direction D2 of the opening 4a by protruding from the second edge 4d toward the imaginary line X.

[0079] A space S1 is formed between two first protrusions 431 arranged along the direction D3 intersecting the inner diameter direction D2. The direction D3 corresponds to the long side direction of the opening 4a when observing the opening 4a from the front. A space S2 is formed between two second protrusions 432 arranged along the direction D3. A plurality of first protrusions 431 respectively face each of the plurality of second protrusions 432. A plurality of spaces S1 are respectively arranged along the inner diameter direction D2 with each of the plurality of spaces S2. A space S3 is provided between the space S1 and the space S2.

[0080] A gap SL through which the coating body 5 passes is formed at the front end of each of the plurality of protrusions 43 along the inner diameter direction D2. The gap SL is formed between each of the plurality of first protrusions 431 and each of the plurality of second protrusions 432. The sum of the lengths of the first protrusion 431 and the second protrusion 432 in the inner diameter direction D2 is shorter than the length of the short side direction of the opening 4a when observed from the front. The gap SL is located between a pair of spaces S3.

[0081] A plurality of branched hairs 54 are respectively located in each of the plurality of spaces S3. The plurality of branched hairs 54 can be located in at least any one of the regions of the space S1, the space S2, the space S3, and the gap SL. For example, the plurality of branched hairs 54 can be respectively located in each of the plurality of spaces S1 and each of the plurality of spaces S2.

[0082] The plurality of protrusions 43 respectively extend along the axial direction D1 of the sleeve 4. The plurality of first protrusions 431 and the plurality of second protrusions 432 include an inner protrusion 433 extending rearward from the opening 4a, and a comb-like member 434 having a length in the axial direction D1 longer than that of the inner protrusion 433. The comb-like member 434 protrudes along the axial direction D1 in the opening 4a. In this specification, sometimes the end of the inner protrusion 433 on the axial direction D1 that is closer to the (front side) than the opening 4a is referred to as the "end", and the end on the opposite side (rear side) to this end is referred to as the "base end". In this specification, sometimes the end of the comb-like member 434 on the axial direction D1 that protrudes from the opening 4a is referred to as the "end", and the end on the opposite side to this end is referred to as the "base end".

[0083] The inner protrusions 433 and the comb members 434 are alternately arranged along the direction D3. In the present embodiment, the sleeve 4 has 4 inner protrusions 433 and 6 comb members 434. The sleeve 4 has 5 first protrusions 431. 3 of the 5 first protrusions 431 are comb members 434, and the remaining 2 first protrusions 431 are inner protrusions 433. The sleeve 4 has 5 second protrusions 432. 3 of the 5 second protrusions 432 are comb members 434, and the remaining 2 second protrusions 432 are inner protrusions 433. In the direction D3, the comb members 434 are located on the outermost sides. That is, comb members 434 are formed at both end portions in the direction D3 in the opening 4a. For example, the position of the axis direction D1 of the base end of the inner protrusion 433 is the same as the position of the axis direction D1 of the base end of the comb member 434.

[0084] The inner protrusion 433 has an inclined portion 433a located on the base end side of the inner protrusion 433, and an extension portion 433b extending from the inclined portion 433a toward the distal end side. The length of the inclined portion 433a in the inner diameter direction D2 (the protruding amount toward the inner diameter direction D2) becomes larger as it gets closer to the opening 4a. The length of the extension portion 433b in the inner diameter direction D2 is, for example, constant.

[0085] The comb member 434 has an inclined portion 434a located on the base end side of the comb member 434, and an extension portion 434b extending from the inclined portion 434a toward the distal end side. The length of the inclined portion 434a in the inner diameter direction D2 becomes larger as it gets closer to the opening 4a. For example, the length of the extension portion 434b in the inner diameter direction D2 is constant. The length of the extension portion 434b in the inner diameter direction D2 is, for example, equal to the length of the extension portion 433b in the inner diameter direction D2. The inclination angle of the inclined portion 434a with respect to the extension portion 434b is, for example, equal to the inclination angle of the inclined portion 433a with respect to the extension portion 433b. The length of the comb member 434 in the axis direction D1 of the extension portion 434b is longer than the length of the inner protrusion 433 in the axis direction D1 of the extension portion 433b.

[0086] As Figure 3 shown, the distal end of the coating body 5 protrudes from the distal ends of the plurality of protrusions 43. More specifically, the distal ends of the branched hairs 54 are located further forward than the distal ends of the comb members 434. The distal ends of all of the plurality of branched hairs 54 may be located further forward than the distal ends of the comb members 434. And, the distal ends of some of the plurality of branched hairs 54 may be located further forward than the distal ends of the comb members 434, and the distal ends of the remaining branched hairs 54 may be located further rearward than the distal ends of the comb members 434.

[0087] The comb member 434 has a reinforcing portion 435, and the reinforcing portion 435 is at the end portion on the side opposite to the inner diameter direction D2 ( Figure 4a thickened part at the upper end or the lower end in the vertical direction. The reinforcing part 435 divides a part of the first edge 4c or the second edge 4d. The comb-shaped member 434 has, for example, two reinforcing parts 435. The reinforcing part 435 protrudes in the direction D3 at the end of the comb-shaped member 434 on the side opposite to the inner diameter direction D2. By providing the reinforcing part 435, deformation of the comb-shaped member 434 can be suppressed.

[0088] A more detailed description of the shape inside the sleeve 4 will be given. The sleeve 4 has a first extension part 4g, a first inclined part 4h, a second inclined part 4j, and a second extension part 4k that respectively form the inner wall of the sleeve 4. The first extension part 4g extends forward from the rear end of the sleeve 4. The first extension part 4g extends along the axis direction D1 from the rear end of the insertion part 41 to approximately the center of the tapered part 42. The first extension part 4g is, for example, circular in shape when observed in the axis direction D1. For example, the inner diameter of the first extension part 4g is constant.

[0089] The first inclined part 4h extends forward from the front end of the first extension part 4g. The rear end of the first inclined part 4h is, for example, smoothly connected to the front end of the first extension part 4g. The amount of protrusion of the first inclined part 4h toward the inner diameter direction D2 becomes larger as it gets closer to the opening part 4a. As Figure 6 shown, the inclination of the first inclined part 4h with respect to the axis direction D1 becomes larger as it gets closer to the opening part 4a. That is, the increase amount of the amount of protrusion of the first inclined part 4h toward the inner diameter direction D2 becomes larger as it gets closer to the opening part 4a.

[0090] The second inclined part 4j extends forward from the front end of the first inclined part 4h. The rear end of the second inclined part 4j is, for example, smoothly connected to the front end of the first inclined part 4h. The length of the second inclined part 4j in the axis direction D1 is shorter than the length of the first inclined part 4h in the axis direction D1. The amount of protrusion of the second inclined part 4j toward the inner diameter direction D2 becomes larger as it gets closer to the opening part 4a. As Figure 6 shown, the inclination of the second inclined part 4j with respect to the axis direction D1 becomes smaller as it gets closer to the opening part 4a. That is, the increase amount of the length of the second inclined part 4j in the inner diameter direction D2 becomes smaller as it gets closer to the opening part 4a.

[0091] The second extension part 4k extends from the front end of the second inclined part 4j to the opening part 4a. The rear end of the second extension part 4k is smoothly connected to the front end of the second inclined part 4j. The amount of protrusion of the second extension part 4k toward the inner diameter direction D2 is constant. The second extension part 4k is in a rounded rectangular shape when observed in the axis direction D1. A plurality of protrusions 43 are provided on the second extension part 4k.

[0092] The function of branching the end of the coating body 5 into a plurality of branches with respect to the sleeve 4 will be described. As described above, the first inclined portion 4h and the second inclined portion 4j connect the first extension portion 4g to the second extension portion 4k, and smoothly connect the inner boundary of the circular first extension portion 4g to the inner boundary of the rounded rectangular second extension portion 4k. Therefore, the first extension portion 4g, the first inclined portion 4h, the second inclined portion 4j, and the second extension portion 4k are sequentially arranged from the rear end of the sleeve 4 toward the front end of the sleeve 4, whereby the coating body 5 is smoothly guided from the opening 4b to the opening 4a.

[0093] More specifically, when the coating body 5 is inserted through the sleeve 4, when the coating body 5 is located in the first extension portion 4g, since the inner diameter of the first extension portion 4g is large, the coating body 5 is not easily constricted by the sleeve 4. The coating body 5 can be easily moved to the front end of the first extension portion 4g. When the coating body 5 reaches the first inclined portion 4h, the coating body 5 is constricted by the sleeve 4, and the density of the coating body 5 becomes larger. The inclination of the first inclined portion 4h with respect to the axial direction D1 becomes larger as it approaches the opening 4a. Compared with the case where the inclination of the first inclined portion 4h with respect to the axial direction D1 becomes smaller as it approaches the opening 4a, the coating body 5 is less likely to contact the first inclined portion 4h, and the coating body 5 is more likely to move along the first inclined portion 4h.

[0094] When the coating body 5 reaches the second inclined portion 4j, the coating body 5 is further constricted by the sleeve 4, and the density of the coating body 5 becomes further larger. The inclination of the second inclined portion 4j with respect to the axial direction D1 becomes smaller as it approaches the opening 4a. Compared with the case where the inclination of the second inclined portion 4j with respect to the axial direction D1 becomes larger as it approaches the opening 4a, the coating body 5 can be smoothly guided to the second extension portion 4k. When the coating body 5 reaches the second extension portion 4k, the coating body 5 is deformed into a rounded rectangular shape when viewed from the axial direction D1. When the coating body 5 is further pushed forward, a part of the coating body 5 comes into contact with the plurality of protrusions 43. When the protrusion 43 is the first protrusion 431, the hair in contact with the protrusion 43 is guided to the space S1 adjacent to the protrusion 43. Similarly, when the protrusion 43 is the second protrusion 432, the hair in contact with the protrusion 43 is guided to the space S2 adjacent to the protrusion 43. Thus, the portion protruding from the opening 4a of the coating body 5 is branched.

[0095] Next, the effects obtained from the cosmetic container 1 according to the present embodiment will be described. In this cosmetic container 1, a space S1 or a space S2 is provided between one protrusion 43 among the plurality of protrusions 43 and the protrusion 43 adjacent to the one protrusion 43. The sleeve 4 has a plurality of protrusions 43. By providing the spaces S1 and S2, when the coating body 5 serving as a brush is inserted into the inside of the sleeve 4, a part of the coating body 5 enters the space S1 or the space S2. At this time, the coating body 5 branches into a plurality. In this cosmetic container 1, a gap SL through which the coating body 5 passes is provided at the front end of each of the plurality of protrusions 43 in the inner diameter direction D2. A space S3 is also provided between the space S1 and the space S2. Thus, a space S1 or a space S2 is provided between the plurality of protrusions 43, a gap SL is provided at the front end of the plurality of protrusions 43 in the inner diameter direction D2, and a space S3 is provided between the space S1 and the space S2. Therefore, even if the tip of the end of the coating body 5 is inserted into the spaces S1, S2, S3, and the gap SL in a non-uniform state, the tip can move between the spaces S1, S2, S3, and the gap SL. As a result, when the coating body 5 is inserted into the sleeve 4, even if the amount of the coating body 5 that enters one of the spaces S1, S2, S3, and the gap SL increases, a part of the coating body 5 moves between the spaces S1, S2, S3, and the gap SL. Therefore, even if the tip of the end of the coating body 5 is inserted in a non-uniform state, the tip moves between the spaces S1, S2, S3, and the gap SL, whereby the uniformity of the tip of the end in the coating body 5 can be improved.

[0096] Furthermore, the plurality of protrusions 43 extend along the axial direction D1 of the sleeve 4. Therefore, even if a force is applied to the coating body 5 sandwiched between two adjacent protrusions 43 in the direction (crossing direction D3) in which the two protrusions 43 are arranged, the coating body 5 is not easily bent. Thereby, the usability of the cosmetic container 1 is improved.

[0097] The plurality of protrusions 43 include a comb-shaped member 434 that protrudes along the axial direction D1 in the opening 4a. In this case, when the end of the cosmetic container 1 is brought into contact with a hairy part of the body, the comb-shaped member 434 can easily come into contact with the skin. In the present embodiment, the end of the branched hair 54 protrudes more than the end of the comb-shaped member 434. Therefore, since the branched hair 54 is sufficiently far from the opening 4a, it is reliably branched, and by using the part of the branched hair 54 that protrudes from the comb-shaped member 434, the length of the branched hair 54 in the part that comes into contact with the hair or skin of the user can be adjusted.

[0098] The end of the coating body 5 protrudes from the ends of the plurality of protrusions 43. In this case, since the coating body 5 branched into a plurality protrudes from the ends of the plurality of protrusions 43 respectively, the end of the coating body 5 can come into contact with a desired part.

[0099] Tilted portions 433a and 434a are provided at the proximal ends of respective ones of the plurality of protrusions 43 in their respective axial directions D1. The lengths of the tilted portion 433a and the tilted portion 434a in the inner diameter direction D2 become longer as they get closer to the opening portion 4a. When the coating body 5 is inserted into the sleeve 4 and a part of the coating body 5 comes into contact with the plurality of protrusions 43, a part of the coating body 5 comes into contact with the proximal end portions of the plurality of protrusions 43, that is, the tilted portions 433a and 434a. According to this structure, the lengths of the tilted portion 433a and the tilted portion 434a in the inner diameter direction D2 become longer as they get closer to the opening portion 4a, so a part of the coating body 5 is smoothly guided in the inner diameter direction D2. Thereby, when a part of the coating body 5 comes into contact with the plurality of protrusions 43, bending of a part of the coating body 5 can be suppressed.

[0100] The plurality of protrusions 43 include a plurality of first protrusions 431 provided on the first edge 4c and a plurality of second protrusions 432 provided on the second edge 4d. Each of the plurality of first protrusions 431 faces each of the plurality of second protrusions 432. A gap SL is provided between each of the plurality of first protrusions 431 and each of the plurality of second protrusions 432.

[0101] According to this structure, a space S1 is provided between one first protrusion 431 and another first protrusion 431 adjacent to the one first protrusion 431. Also, a space S2 is provided between one second protrusion 432 and another second protrusion 432 adjacent to the one second protrusion 432. Therefore, a part of the coating body 5 branches into the coating body 5 on the first edge 4c side that enters the space S1 and the coating body 5 on the second edge 4d side that enters the space S2. Since each first protrusion 431 faces each second protrusion 432, the coating body 5 on the first edge 4c side and the coating body 5 on the second edge 4d side are arranged in the inner diameter direction D2. The tip of the end of the inserted coating body 5 can move between the space S1 and the space S2. As a result, when the coating body 5 is inserted into the sleeve 4, even if the amount of the coating body on the first edge 4c side or the amount of the coating body on the second edge 4d side becomes larger, a part of the coating body 5 moves between the first edge 4c and the second edge 4d. Thereby, the uniformity of the tip of the end of the coating body 5 in the direction (inner diameter direction D2) in which the first protrusion 431 and the second protrusion 432 face each other can be improved, and thus the uniformity of the tip of the end in the coating body 5 can be further improved.

[0102] Reference Figures 7 to 9 The cosmetic container according to the modification will be described. The cosmetic container according to the modification is different from the aforementioned cosmetic container 1 in that it has a sleeve 4A different from the aforementioned sleeve 4. Figure 7 is a front view of the sleeve 4A.Figure 8 is a cross-sectional view of the sleeve 4A taken along the axis of the sleeve 4A. Figure 9 is another cross-sectional view of the sleeve 4A taken along the axis of the sleeve 4A. The sleeve 4A is different from the sleeve 4 in that it has a plurality of protrusions 91 whose length in the axial direction D1 is longer than that of the aforementioned protrusion 43. The plurality of protrusions 91 each extend toward the proximal end side beyond the intermediate line M that passes through the center of the axial direction D1 of the sleeve 4A. The intermediate line M is an imaginary straight line that passes through the center of the axial direction D1 of the sleeve 4A and extends in the direction D3 in a cross-section of the sleeve 4A that extends in the axial direction D1 and the direction D3. The "proximal end side" means the side opposite to the opening 4a. One end of the plurality of protrusions 91 in the axial direction D1 is located on the proximal end side of the intermediate line M.

[0103] As Figure 7 shown, the plurality of protrusions 91 each protrude in the inner diameter direction D2 of the opening 4a. The sleeve 4A has a protrusion 91 that protrudes from the first edge 4c toward the imaginary line X and a protrusion 91 that protrudes from the second edge 4d toward the imaginary line X. Hereinafter, the protrusion 91 that protrudes from the first edge 4c toward the imaginary line X may sometimes be referred to as the "protrusion 91 on the first edge 4c side", and the protrusion 91 that protrudes from the second edge 4d toward the imaginary line X may be referred to as the "protrusion 91 on the second edge 4d side". The protrusion 91 on the first edge 4c side and the protrusion 91 on the second edge 4d side are opposed to each other in the inner diameter direction D2. The sleeve 4A has, for example, six protrusions 91, and has three protrusions 91 on the first edge 4c side and three protrusions 91 on the second edge 4d side.

[0104] A space S1 is formed between the plurality of protrusions 91 on the first edge 4c side that are arranged in the direction D3 that intersects both the axial direction D1 and the inner diameter direction D2. A space S2 is formed between the plurality of protrusions 91 on the second edge 4d side that are arranged in the direction D3. A space S3 is formed between the space S1 and the space S2. A gap SL through which the coating body 5 passes is formed at the front end of each of the plurality of protrusions 91 in the inner diameter direction D2. The gap SL is formed between the protrusion 91 on the first edge 4c side and the protrusion 91 on the second edge 4d side. Details of the plurality of protrusions 91 will be described later.

[0105] A more detailed description of the internal shape of the sleeve 4A will be given. As Figure 8As shown, the sleeve 4A has a front-side extension 4n, a rear-side extension 4p, and a reduced-diameter portion 4q located between the front-side extension 4n and the rear-side extension 4p. The front-side extension 4n, the rear-side extension 4p, and the reduced-diameter portion 4q respectively constitute the inner wall of the sleeve 4A. The front-side extension 4n extends rearward from the front end (tip) of the tapered portion 42. The front-side extension 4n includes an opening 4a. The rear-side extension 4p extends forward from the rear end (base end) of the insertion portion 41. The rear-side extension 4p includes an opening 4b. The rear-side extension 4p is, for example, circular in shape when viewed in the axial direction D1. For example, the inner diameter of the rear-side extension 4p is constant in the axial direction D1.

[0106] The rear end of the reduced-diameter portion 4q is, for example, smoothly connected to the front end of the rear-side extension 4p. The front end of the reduced-diameter portion 4q is, for example, smoothly connected to the rear end of the front-side extension 4n. The amount of protrusion of the reduced-diameter portion 4q toward the inner-diameter direction D2 becomes larger as it gets closer to the opening 4a.

[0107] A more detailed description of the plurality of protrusions 91 will be given. As Figure 8 and Figure 9 shown, the plurality of protrusions 91 respectively protrude in the axial direction D1 in the opening 4a. The protrusion 91 has a first extension portion 91a on the tip side of the protrusion 91, a second extension portion 91b on the base end side of the protrusion 91, a connecting portion 91c located between the first extension portion 91a and the second extension portion 91b, and an inclined portion 91d located on the base end side further than the second extension portion 91b.

[0108] The first extension portion 91a is formed on the inner wall constituting the front-side extension 4n. The length of the first extension portion 91a in the inner-diameter direction D2 (the amount of protrusion toward the inner-diameter direction D2) is, for example, constant. The first extension portion 91a includes a portion that protrudes in the axial direction D1 in the opening 4a and a portion that extends toward the base end side from the protruding portion. The base end of the first extension portion 91a is located near the base end of the front-side extension 4n. For example, the base end of the first extension portion 91a is located on the base end side further than the base end of the front-side extension 4n.

[0109] The connecting portion 91c is formed on the inner wall constituting the reduced-diameter portion 4q. More specifically, the amount of protrusion of the connecting portion 91c toward the inner-diameter direction D2 is, for example, constant. This amount of protrusion represents the amount of protrusion of the connecting portion 91c from the inner wall constituting the reduced-diameter portion 4q. The base end of the connecting portion 91c is located near the base end of the reduced-diameter portion 4q. Among the connecting portions 91c arranged in the direction D3, the base end of the connecting portion 91c located in the center is located on the base end side further than the base end of the connecting portion 91c adjacent to this connecting portion 91c.

[0110] The second extension portion 91b is formed on the inner wall constituting the rear side extension portion 4p. The length of the second extension portion 91b in the inner diameter direction D2 is, for example, constant. The proximal end of the second extension portion 91b is, for example, located at the center in the axial direction D1 of the rear side extension portion 4p. The inclined portion 91d is formed on the inner wall constituting the rear side extension portion 4p. The length of the inclined portion 91d in the inner diameter direction D2 (the protruding amount toward the inner diameter direction D2) becomes larger as it gets closer to the opening portion 4a. The proximal end of the inclined portion 91d is located on the end side (opening portion 4a side) closer to the end than the rear end 4m. However, the position of the proximal end of the inclined portion 91d may be the same as the position of the rear end 4m.

[0111] The sleeve 4A may not have the inclined portion 91d. The proximal end of the second extension portion 91b may be located on the proximal end side with respect to the intermediate line M. The position of the proximal end of the second extension portion 91b may be the same as the position of the rear end 4m. Further, the protrusion 91 may protrude from the rear end 4m.

[0112] The function of branching the end of the coating body 5 into a plurality of parts by the sleeve 4A will be described. As described above, the rear side extension portion 4p, the reduced diameter portion 4q, and the front side extension portion 4n are sequentially provided from the proximal end of the sleeve 4A toward the distal end of the sleeve 4A, whereby the coating body 5 is smoothly guided from the opening portion 4b to the opening portion 4a.

[0113] Further, when the coating body 5 is located in the rear side extension portion 4p, the inner diameter of the rear side extension portion 4p is large, so that the coating body 5 is not converged too tightly by the sleeve 4A. If the coating body 5 is pushed toward the opening portion 4a in this state, the coating body 5 is gradually and tightly converged by the sleeve 4A when the coating body 5 passes through the reduced diameter portion 4q and when the coating body 5 passes through the front side extension portion 4n.

[0114] In this modified example, since the protrusion 91 extends on the proximal end side with respect to the intermediate line M, the distance from the opening portion 4b to the proximal end of the protrusion 91 is shorter than the distance from the opening portion 4b to the intermediate line M. Therefore, the coating body 5 inserted from the opening portion 4b quickly reaches the plurality of protrusions 91, and a part of the coating body 5 smoothly enters between the plurality of protrusions 91 (inclined portion 91d) adjacent in the direction D3. If a part of the coating body 5 enters between the plurality of protrusions 91 adjacent in the direction D3, movement of this part of the coating body 5 in a direction crossing the axial direction D1 is suppressed. If the coating body 5 is further pushed toward the opening portion 4a, the coating body 5 advances toward the opening portion 4a along the plurality of protrusions 91. Then, the coating body 5 is respectively guided to the spaces S1, S2, S3, and the gap SL. As a result, the portion protruding from the opening portion 4a of the coating body 5 is branched.

[0115] Next, the effects obtained from the cosmetic container according to the modified example will be described. In the cosmetic container according to the modified example, the plurality of protrusions 91 each extend to a side opposite to the opening 4a and closer to the center of the axial direction D1 of the sleeve 4A. Further, when the coating body 5 is inserted into the sleeve 4A, if the movement of the coating body 5 in the direction intersecting the axial direction D1 is not properly restricted by the plurality of protrusions 91, the advancing directions of some hairs of the coating body 5 may not be consistent with those of other hairs. In this case, the arrangement state of the coating body 5 may be disordered. As shown in this modified example, when the plurality of protrusions 91 each extend to a side opposite to the opening 4a and closer to the center of the axial direction D1 of the sleeve 4A, the distance from the rear end 4m to the plurality of protrusions 91 can be shortened. Thereby, when the coating body 5 is inserted into the sleeve 4A, the coating body 5 can quickly enter between the plurality of protrusions 91 inside the sleeve 4A without disturbing the arrangement state of the coating body 5. Therefore, it is possible to prevent the tips of the ends of the coating body 5 from entering between the plurality of protrusions 91 in a non-uniform state. As a result, the uniformity of the tips of the ends in the coating body 5 can be further improved.

[0116] As described above, the embodiments and modified examples of the cosmetic container according to the present invention have been described. However, the cosmetic container according to the present invention is not limited to the foregoing embodiments or modified examples, and further modifications can be made within the scope of the gist described in the claims. That is, the shape, size, material, number, and arrangement of each part of the cosmetic container according to the present invention can be appropriately changed within the scope of the above gist.

[0117] In the foregoing embodiment, an example in which the plurality of protrusions 43 include the internal protrusion 433 and the comb member 434 has been described. However, the plurality of protrusions 43 may include the internal protrusion 433 and not include the comb member 434. Further, the plurality of protrusions 43 may include the comb member 434 and not include the internal protrusion 433.

[0118] In the foregoing embodiment, an example in which the plurality of protrusions 43 include the first protrusion 431 and the second protrusion 432 has been described. However, the plurality of protrusions 43 may include the first protrusion 431 and may not include the second protrusion 432. In this case, a gap SL is provided between the first protrusion 431 and the second edge 4d. The space S2 is not provided. A space is provided between the space S1 and the second edge 4d.

[0119] In the foregoing embodiment, an example in which the coating body 5 protrudes more than the comb member 434 has been described. However, the coating body 5 may also protrude more than the opening 4a and not more than the comb member 434. That is, the end of the coating body 5 may be located between the end of the opening 4a and the end of the comb member 434. In this case, when the comb member 434 comes into contact with the skin, the hair on the user's body will enter between the two comb members 434 arranged in a direction intersecting the inner diameter direction. Therefore, it is possible to bring the coating body 5 into contact with the part of the body where the hair grows, and it is difficult for the coating body 5 to come into contact with the skin. In this case, it is possible to suppress the attachment of the cosmetic to the skin due to the coating body 5.
