[0011] Hereinafter, each embodiment of the present disclosure will be described with reference to the accompanying drawings. Note that, in the description of the specification and drawings relating to each embodiment, components having substantially the same or corresponding functional configurations may be given the same reference numerals to omit redundant description. In addition, in order to facilitate understanding, the scale of each part in the drawings may differ from the actual scale.

[0012] For ease of explanation, an XYZ Cartesian coordinate system is set in the figure. For the coordinate axis perpendicular to the paper surface of the drawing, a cross in a circle indicates that the direction toward the back of the paper surface is positive, and a black circle in a circle indicates that the direction toward the front of the paper surface is positive. However, this coordinate system is defined for the purpose of explanation and does not limit the position of the cosmetic container according to this embodiment.

[0013] The X-axis and Y-axis are, for example, axes parallel to a horizontal plane when the cosmetic container is placed on the horizontal plane. The Z-axis is, for example, an axis perpendicular to the horizontal plane when the cosmetic container is placed on the horizontal plane. Note that the +Z side of the Z-axis direction may be referred to as the upper side, and the -Z side as the lower side.

[0014] <<First embodiment>> <Cosmetic container 1> 1 is a side view of a cosmetics container 1 according to embodiment 1. The cosmetics container 1 according to embodiment 1 is a cosmetics container for mascara that can also be used as an applicator for applying mascara liquid, for example.

[0015] The cosmetic container 1 is not limited to storing mascara liquid, and may be used to store other cosmetics. For example, it may be used for eye cosmetics that can be used for multiple purposes, such as eyelash growth agents, mascara bases, eyelash coating agents, eyelash extension coating agents, eyeliner liquids, and cosmetic compositions that can be used as both mascara and eyeliner. Furthermore, by changing the shape of the applicator, it may be used for liquid cosmetics that are applied via other applicators, such as lipstick cosmetics, partial skin cosmetics, nail polish, etc. Furthermore, it may be used to store liquids other than cosmetics.

[0016] The cosmetic container 1 includes a main body 10 and a lid 20. The lid 20 is attached to and detached from the main body 10 by rotating it about a central axis AX.

[0017] <Main body 10> The following description will be given taking mascara as an example. The main body 10 is a container for storing mascara liquid. In other words, the main body 10 is a container for storing cosmetics.

[0018] 2 is a side view of the main body 10 of the cosmetic container 1 according to the first embodiment. The main body 10 includes a storage portion 11 and a connecting portion 12.

[0019] The storage section 11 has a cavity therein for storing the cosmetic material. The cosmetic material is stored in the cavity of the storage section 11.

[0020] The connecting part 12 connects the main body part 10 and the lid part 20. It is located on the upper side (+Z side) of the storage part 11. The connecting part 12 has a male thread 12S on the side. The connecting part 12 has an opening 12H at the top. The opening 12H connects to the internal cavity of the storage part 11. The application part 21 and the support rod 22 (see FIG. 3) of the lid part 20 are inserted into the inside of the storage part 11 through the opening 12H.

[0021] The male thread 12S of the connecting portion 12 and the female thread 231S of the lid portion 20 (see FIG. 6) are fitted together, thereby connecting the lid portion 20 to the main body portion 10. The opening 12H is sealed by the lid portion 20 when the main body portion 10 and the lid portion 20 are fitted together. By sealing the opening 12H with the lid portion 20, the interior of the cosmetic container 1 is kept airtight with the lid portion 20 connected to the main body portion 10.

[0022] By keeping the inside of the cosmetic container 1 airtight, it is possible to store the cosmetics for a long period of time inside the cosmetic container 1. In addition, by keeping the inside of the cosmetic container 1 airtight, it is possible to prevent the cosmetics from spilling out of the cosmetic container 1.

[0023] Furthermore, by removing the lid part 20 from the main body part 10, the support rod 22 of the lid part 20 and the application part 21 pass through the opening 12H. The connecting part 12 is equipped with a restrictor (wiper) for adjusting the amount of cosmetic adhering to the application part 21 to an appropriate amount. When the application part 21 passes through the restrictor, a portion of the cosmetic adhering to the application part 21 is returned to the main body part 10 by the restrictor. As a portion of the cosmetic adhering to the application part 21 (excess amount) is returned to the main body part 10 by the restrictor, the amount of cosmetic adhering to the application part 21 taken out through the opening 12H is adjusted to an appropriate amount.

[0024] <Lid part 20> The lid portion 20 functions as a lid for the main body portion 10 and also as an applicator for applying cosmetics.

[0025] 3 is a side view of the lid part 20 of the cosmetic container 1 according to the first embodiment. The lid part 20 has an application part 21, a support rod 22, and a lid 23. The application part 21, the support rod 22, and the lid 23 are formed using a three-dimensional printer. By forming the lid part 20 using a three-dimensional printer, the application part 21, the support rod 22, and the lid 23 of the lid part 20 are integrally formed from a single material.

[0026] The lid portion 20 is made of a material that can be formed by a three-dimensional printer. The lid portion 20 is made of a resin such as epoxy, acrylic, polycarbonate, ABS (acrylonitrile butadiene styrene), polyamide, PP (polypropylene), etc. The lid portion 20 is made of a material having a flexural modulus of 1000 MPa or more.

[0027] Three-dimensional printers create three-dimensional shapes using, for example, stereolithography, powder sintering additive manufacturing, fused deposition modeling, sheet lamination, and droplet ejection methods.

[0028] Lid unit 20 has applicator unit 21, on the tip of support rod 22 opposite lid 23, where multiple hair-like bodies are formed for applying cosmetics to a target. A user uses lid 23 by grasping it. In other words, lid 23 of lid unit 20 is used as a handle. The user places applicator unit 21 against a target (eyelashes) and applies mascara liquid to the target (eyelashes).

[0029] The lid 23 of the lid portion 20 will be described in detail. Fig. 4 is a side view of the lid portion 20 of the cosmetics container 1 according to the first embodiment. Fig. 5 is a top view of the lid portion 20 of the cosmetics container 1 according to the first embodiment. Figs. 6 and 7 are cross-sectional views of the lid portion 20 of the cosmetics container 1 according to the first embodiment. Specifically, Fig. 6 is a cross-sectional view taken along line II-II in Fig. 5. Fig. 7 is a cross-sectional view taken along line II in Fig. 4.

[0030] The lid 23 has a first end 231, a central portion 232, a second end 233, a third end 234, and a plurality of rod-shaped portions 235. Specifically, the lid 23 has 16 rod-shaped portions 235. Note that the number of rod-shaped portions 235 is not limited to 16. In consideration of the ease of gripping the lid 23, the number of rod-shaped portions 235 should be at least four or more, and is preferably eight or more.

[0031] The first end 231 functions as a lid that seals the opening 12H of the main body 10. The first end 231 is cylindrical with one open end and the other closed. That is, the outer shape of the first end 231 is cylindrical. The first end 231 has a female thread 231S inside. Note that the shape of the first end 231 is not limited to a cylindrical shape as long as it can be connected to the connecting portion 12, and may be, for example, a cylindrical shape with an elliptical cross section or a cylindrical shape with a polygonal cross section.

[0032] The central portion 232 is located above the first end portion 231. The first end portion 231 and the central portion 232 are integrally formed. The central portion 232 has a rod-like shape with a circular cross section. The central portion 232 is located on the center side of the lid 23 including the central axis AX. The shape of the central portion 232 is not limited to a rod-like shape with a circular cross section, and may be, for example, a rod-like shape with an elliptical cross section or a rod-like shape with a polygonal cross section. Furthermore, the shape of the central portion 232 is not limited to a rod-like shape, and may be a cylindrical shape.

[0033] The second end 233 is located at the upper end of the central portion 232. The second end 233 is a disk-shaped member. The central portion 232 and the second end 233 are integrally formed. The shape of the second end 233 may be appropriately changed according to the shape of the first end 231.

[0034] Each of the multiple rod-shaped portions 235 has a first rod-shaped portion 235A and a second rod-shaped portion 235B. The first rod-shaped portion 235A of each of the multiple rod-shaped portions 235 extends from the first end portion 231 in a direction inclined toward the center portion 232 with respect to a direction perpendicular to the XY plane. As shown in Figures 5 and 7, the first rod-shaped portions 235A of each of the multiple rod-shaped portions 235 are provided at equal intervals in the circumferential direction with respect to the central axis AX. That is, the multiple first rod-shaped portions 235A are arranged in a cage shape so as to surround the center portion 232.

[0035] The second rod-shaped portion 235B of each of the multiple rod-shaped portions 235 extends from the upper end of the first rod-shaped portion 235A to the second end 233 in a direction parallel to the XY plane.

[0036] Each of the rod-shaped portions 235 has a rod-like shape with a circular cross section, but the cross-sectional shape is not limited to a circle as long as it satisfies the relationship between the deformation amount and the load described below. For example, the cross section of each of the rod-shaped portions 235 may be an ellipse or a polygon such as a triangle or a rectangle. When the cross section of each of the rod-shaped portions 235 has corners such as a triangle, it is desirable to arrange the surfaces so that they face outward.

[0037] A circular third end 234 is formed at the joint between the first rod-shaped portion 235A and the second rod-shaped portion 235B. The shape of the second end 233 may be appropriately changed according to the shape of the first end 231.

[0038] The rod-shaped portions 235 are an example of an outer periphery. The central axis AX is an example of a rotation axis.

[0039] <Relationship between deformation and stress at the periphery> In order to evaluate the ease of gripping (holdability) of rod-shaped portion 235, the relationship between stress and deformation amount in rod-shaped portion 235 will be described.

[0040] FIG. 8 is a diagram illustrating the amount of deformation in the lid 20 of the cosmetic container 1 according to the first embodiment.

[0041] As shown in FIG. 8, one side of the lid 23 of the lid portion 20 is fixed by a fixing member 100. Then, the rod-shaped portion 235 on the other side of the lid 23 of the lid portion 20 is pressed by a pressing member 110. The pressing member 110 presses the center of the rod-shaped portion 235 with a load F. The length L (length of the deformed portion) of the rod-shaped portion 235 is, for example, 30 mm. The tip of the pressing member 110 is spherical. The radius of the sphere at the tip of the pressing member 110 is, for example, 7.5 mm. The amount of displacement d when pressed with the load F is measured. Here, a case where a load is applied to one side of the lid 23 of the lid portion 20 will be described.

[0042] 9 is a diagram showing the relationship between the deformation amount and load of rod-shaped portion 235 when rod-shaped portion 235 is pressed by pressing member 110. Here, measurements were performed on Sample S, Sample M, and Sample H, which have different rigidity in rod-shaped portion 235. Specifically, Sample S, Sample M, and Sample H are made of the same material, but have rod-shaped portion 235 with different thicknesses. Sample S, Sample M, and Sample H are made of acrylic resin.

[0043] 9, line S1 represents the measurement results for sample S, line S2 represents the measurement results for sample M, and line S3 represents the measurement results for sample H. When rod-shaped portion 235 is to be deformed by the same amount, the required load increases in the order of sample S, sample M, and sample H. For example, when the deformation amount is 1 mm, a load of 3.4 N is required for sample S, 4.9 N for sample M, and 7.6 N for sample H.

[0044] Samples S, M, and H were each evaluated for their effect of improving holding ability and practical strength during normal use.

[0045] The effect of improving the holding power was evaluated by a specialist evaluation panel. The effect of improving the holding power was evaluated by sensory evaluation to see whether the holding power was improved when holding Sample S, Sample M, or Sample H, compared to when holding a conventional mascara container with a lid made of a rectangular parallelepiped material. In addition, the practical strength during normal use was evaluated by checking whether Sample S, Sample M, and Sample H had any deformation or breakage.

[0046] A summary of the evaluation results is shown in Table 1. Regarding the effect of improving holding ability, A indicates that the sample (sample S, sample M, or sample H) was evaluated as being easier to grip (has holding ability) than the conventional container. Also, B indicates that it was judged that there was little difference from the conventional container.

[0047] For the practical strength under normal use, A indicates that there was no deformation or breakage after normal use, and C indicates that deformation or breakage occurred after normal use.

[0048] [Table 1]

[0049] From the above results, it can be seen that the holding power improvement effect is better than or at least equivalent to that of conventional cosmetic containers for Samples S, M, and H. In addition, there were no problems with the practical strength of Samples M and H in normal use.

[0050] Sample S was deformed and broken during normal use. For the hard resin that forms the lid 20 and has a flexural modulus of 1000 MPa or more, a load of 3.4 N to change the displacement by 1 mm is considered to be the limit for maintaining practical strength that can withstand normal use. In other words, if the load to displace one side by 1 mm is less than 3.5 N, there is a high possibility that the sample will deform or break due to the load applied during normal use.

[0051] Therefore, in order to improve the holding ability, it is desirable that the load required to displace one side of the rod-shaped portion 235 by 1 mm be in the range of 3.5 N to 7.5 N.

[0052] <Actions and Effects> The cosmetic container 1 of the first embodiment can provide the lid part 20 in which the application part 21 that can be used as an applicator is integrated with the lid 23. Furthermore, the lid part 20 of the cosmetic container 1 can be easily held by the user when used as an applicator.

[0053] The user attaches the lid 23 of the lid portion 20 to the main body portion 10 by tightening the screws. Therefore, the lid portion 20 is made of a hard resin in order to maintain a predetermined structure. On the other hand, if the part that the user holds is made of a hard resin, the part to be held is too hard and difficult to hold.

[0054] Therefore, the lid portion 20 of the cosmetic container 1 has a plurality of rod-shaped portions 235 that are structurally easily deformed, thereby making the portion to be gripped flexible.

[0055] For example, as disclosed in JP-A-08-164692 and JP-A-60-204457, it is possible to use an elastic or flexible material for the gripping portion. However, since the gripping portion needs to be made of a different material, the number of materials required increases. Also, the number of assembly steps increases, which increases the manufacturing cost.

[0056] According to the cosmetic container 1 of the present embodiment, the lid 20 is formed from a single material, which reduces the amount of material required. Also, according to the cosmetic container 1 of the present embodiment, the lid 20 can be easily formed by using, for example, a three-dimensional printer.

[0057] <<Second embodiment>> <Lid part 40> 10 is a side view of the lid part 40 of the cosmetics container according to the second embodiment. The cosmetics container according to the second embodiment has a lid part 40 instead of the lid part 20 of the cosmetics container 1 according to the first embodiment. The lid part 40 has an applicator part, a support rod 42, and a lid 43. Note that the applicator part has a similar configuration to the applicator part 21 of the lid part 20, so a description thereof will be omitted.

[0058] The application portion of the lid portion 40, the support rod 42, and the lid 43 are formed using a three-dimensional printer. By forming the lid portion 40 using a three-dimensional printer, the application portion of the lid portion 40, the support rod 42, and the lid 43 are integrally formed from a single material.

[0059] The lid 43 has a first end portion 431, a central portion 432, a second end portion 433, and a lattice portion 435. Note that the first end portion 431 and the central portion 432 have the same configurations as the first end portion 231 and the central portion 232 of the lid 23, respectively, and therefore a description thereof will be omitted.

[0060] The second end portion 433 is located at an upper end portion of the central portion 432. The second end portion 433 is a disk-shaped member. The central portion 432 and the second end portion 433 are integrally formed.

[0061] The lattice portion 435 is formed in a lattice shape by intersecting rod-shaped members that are inclined obliquely with respect to the direction perpendicular to the XY plane (Z-axis direction). That is, the lattice portion 435 is formed in a lattice shape by a plurality of rod-shaped members that extend in intersecting directions. The lattice portion 435 is provided at a predetermined distance from the central axis AX. That is, the lattice portion 435 is provided so as to surround the central portion 432.

[0062] The lattice portion 435 is an example of the outer periphery. The shape of the lattice portion 435 is not limited to the example shown in Fig. 10, and the spacing between the lattices and the shape of the rod-shaped members constituting the lattice may be changed so as to satisfy the relationship between the deformation amount and the load described above.

[0063] <<Third embodiment>> <Lid part 50> 11 is a side view of the lid part 50 of the cosmetics container according to the third embodiment. The cosmetics container according to the third embodiment has a lid part 50 instead of the lid part 20 of the cosmetics container 1 according to the first embodiment. The lid part 50 has an applicator part, a support rod 52, and a lid 53. Note that the applicator part has a similar configuration to the applicator part 21 of the lid part 20, so a description thereof will be omitted.

[0064] The application portion of the lid portion 50, the support rod 52, and the lid 53 are formed using a three-dimensional printer. By forming the lid portion 50 using a three-dimensional printer, the application portion of the lid portion 50, the support rod 52, and the lid 53 are integrally formed from a single material.

[0065] The lid 53 has a first end portion 531, a central portion 532, a second end portion 533, and a chainmail portion 535. Note that the first end portion 531 and the central portion 532 have the same configurations as the first end portion 231 and the central portion 232 of the lid 23, respectively, and therefore a description thereof will be omitted.

[0066] The second end portion 533 is located at an upper end portion of the central portion 532. The second end portion 533 is a disk-shaped member. The central portion 532 and the second end portion 533 are integrally formed.

[0067] The chainmail portion 535 is formed in a chainmail shape by connecting a plurality of annular members in a direction perpendicular to the XY plane (Z-axis direction) and in a direction parallel to the ZY plane. The chainmail portion 535 is provided at a predetermined distance from the central axis AX. That is, the chainmail portion 535 is provided so as to surround the central portion 532.

[0068] The chainmail portion 535 is an example of the outer circumferential portion. The shape of the chainmail portion 55 is not limited to the example shown in Fig. 11, and the interval and shape of the annular members may be changed so as to satisfy the relationship between the deformation amount and the load described above.

[0069] It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The above-described embodiments may be omitted, substituted, or modified in various forms without departing from the scope and spirit of the appended claims.

[0070] For example, the shape of the outer peripheral portion surrounding the central portion is not limited to a cage shape, a lattice shape, or a chainmail shape, and may be changed as appropriate so as to satisfy the relationship between the deformation amount and the load described above.

[0071] Also, only the lid portion according to this embodiment (e.g., lid portion 20 shown in FIG. 3) may be used as a cosmetic applicator. For example, when lid portion 20 is used as a cosmetic applicator, the female screw 213S shown in FIG. 6 may or may not be formed. For example, application portion 21 of lid portion 20 is one example of an application portion. The same applies to lid portion 40 and lid portion 50. [Explanation of symbols]
