Description

Title of the invention: COSMETIC FORMULA APPLICATOR technical field

[0001] The present application relates to a cosmetic formula applicator. STATE OF THE ART

[0002] Conventionally, cosmetic formula applicators for applying a cosmetic formula, such as mascara, to a targeted object have been suggested (for example, US7980253B2 and US8689808B2). Generally, such cosmetic formula applicators include a comb-like application portion for applying the cosmetic formula to the eyelashes.

[0003] However, there is a need to improve the sensoriality and operability of such a cosmetic formula applicator. DISCLOSURE OF THE INVENTION

[0004] Thus, the object of the invention is to propose a cosmetic formula applicator which has improved sensoriality and operability.

[0005] The present invention employs the following means to solve the above problem. A cosmetic formula applicator according to the present invention is made of metal and comprises: • a portion of a stem having a columnar shape and extending in an axial direction; • a round application portion provided on a distal end of the stem portion; and • a comb-like application portion including a plurality of plate portions arranged in the axial direction and on a portion of the stem portion located distal to the round application portion, with gaps between these, • in which the external diameters of a plurality of plate portions change in the axial direction.

[0006] According to this invention, since the cosmetic formula applicator is made from a metal with high thermal conductivity, the cosmetic formula applicator can provide a user with a sensation of freshness when the cosmetic formula applicator comes into contact with a targeted object (such as an eyelid) so as to provide the user with the sensory feedback indicating that the cosmetic formula applicator is making contact with the targeted object. In particular, when the round application portion comes into contact with the targeted object, it is easy for The cosmetic formula applicator provides a sensory experience for the user. Furthermore, since the cosmetic formula is applied to the target object, such as an eyelash, using the comb-like application portion, while the cosmetic formula is applied to other target objects, such as an eyelid, using the round application portion, the applicator's operability for applying the cosmetic formula according to the target object can be improved. Because multiple plate portions forming the comb-like application portion create a comb-like effect, these plate portions separate the eyelashes when the cosmetic formula is applied to the eyelashes with the comb-like application portion, resulting in a smooth finish.In particular, since the external diameters of the plate portions in the comb application portion change in the axial direction when the cosmetic formula is applied with the comb application portion, the cosmetic formula is applied to the eyelashes according to the length of the eyelashes.

[0007] Furthermore, the external diameters of a plurality of plate portions can change in the axial direction.

[0008] According to this invention, since the external diameters of the plate portions increase from one end to the other end of the stalk portion, short eyelashes, located at the corners of the eye, can have the cosmetic formula applied by means of certain plate portions from a group of plate portions that have a relatively small diameter, while long eyelashes, located between the corners of the eye, can have the cosmetic formula applied by means of certain plate portions from a group of plate portions that have a relatively large external diameter. In this way, the cosmetic formula can be applied to the roots of the eyelashes for both short and long eyelashes.

[0009] In addition, an external diameter of the portion of the rod portion, on which the comb application portion is provided, can change in the axial direction.

[0010] According to this invention, since the gaps between the plate portions serve as spaces for retaining the cosmetic formula, and since the external diameter of the stalk portion increases from one end to the other, the distance between the outer circumferential edge of the plate portion and the bottom of said retaining space for the cosmetic formula located between the plate portions does not become too large. Thus, when applying the cosmetic formula using some of the plate portions of a group of plate portions that have a relatively large external diameter, the cosmetic formula retained in said space located between the plate portions is applied appropriately to the eyelashes.

[0011] In addition, the round application portion can be a ball application portion.

[0012] According to this invention, since the ball application portion has a ball shape, the ball application portion can offer a softer, more certain sensory experience to the user.

[0013] Furthermore, an external diameter of the ball application portion can be equal to that of the plate portion smaller or larger than it.

[0014] According to this invention, the portion of a plate of a plurality of plate portions that is closest to the ball application portion is prevented from unintentionally coming into contact with the target object when applying the cosmetic formula to the target object by means of the ball application portion, and thus the operability of the cosmetic formula applicator by means of the ball application portion can be improved.

[0015] In addition, the applicator may include a fixing pin attached to a handle or is made in one piece with the rod, as a single piece of material.

[0016] According to this invention, by attaching the cosmetic formula applicator to the handle, the operability of the cosmetic formula applicator by means of the handle can be improved.

[0017] In addition, the cosmetic formula applicator can be made of aluminum, stainless steel, gold, silver, copper or brass.

[0018] According to this invention, by making the cosmetic formula applicator out of aluminium, stainless steel, gold, silver, copper or brass, the cosmetic formula applicator 1 can substantially improve the sensoriality of the targeted object.

[0019] In addition, a gap between one of the plate portions and the adjacent plate portion may be between 0.5 mm and 0.7 mm, and / or, an amount of radial outward projection of the plate portion relative to an external surface of the rod portion may be between 0.2 mm and 0.8 mm, and / or, an upper surface and a lower surface of the plate portion may be formed with an upper tapered portion and a lower tapered portion, respectively, and a gap between the lower tapered portion of one of the plate portions and the upper tapered portion of an adjacent plate portion located on the lower side of one of the plate portions may be between 0.05 mm and 0.3 mm, and / or a thickness of one of the upper tapered portions and the lower tapered portion may be between 0.1 mm and 0.4 mm.

[0020] According to this invention, given that the cosmetic formula applicator has one of these sizes, it is possible to offer the user improved sensoriality and operability. Brief description of the drawings

[0024] An embodiment of the cosmetic formula applicator (hereinafter referred to as an applicator) according to the present invention will be described. In the figures used in the following description, each element is scaled accordingly to make each element recognizable. As shown in Figures 1 to 3, the applicator 1 according to the present embodiment comprises a stem portion 11 with a circular column shape, a ball-shaped application portion 12 provided on a distal end of the stem portion 11, and a comb application portion 14 provided with a plurality of plate portions 14 projecting radially outward from the stem portion 11. The stem portion 11, the ball application portion 12, and the comb application portion 13 are arranged such that their central axes lie on a common axis, and the common axis will be referred to as the applicator axis O.Hereafter, the direction towards the ball application portion 12 along the applicator axis is referred to as the upward direction, and the opposite direction to the upward direction is referred to as the downward direction. Furthermore, the direction perpendicular to the applicator axis O is referred to as the radial direction, and the direction around the applicator axis O is referred to as the circumferential direction.

[0025] The applicator 1 is made from metals such as aluminum, lead-free aluminum, recycled aluminum, lead-free recycled aluminum, stainless steel, gold, silver, copper, and brass. Furthermore, the surface of the applicator is anodized or PVD-coated. The thermal conductivities of the above-mentioned metals are as follows.

[0026] [Tables 1] Material Thermal Conductivity (W / mK) Silver 406 Copper 385 Gold 314 Aluminum 205 Brass 109 Steel 50.2

[0027] The applicator is machined for example by a Swiss bar turning process. Machining using a Swiss bar turning process eliminates the need for molds for the fa- The bracing of the applicator 1 facilitates the change in the design of the applicator 1.

[0028] The rod portion 11 has a truncated circular cone shape with an external diameter that increases from its upper end to its lower end. The upper and lower ends of the rod portion 11 are formed with upper and lower flange portions projecting radially outwards, respectively. The upper flange 21 has a truncated cone shape with an external diameter that increases from its upper end to its lower end, and the external diameter at the lower end of the upper flange 21 is equal to the external diameter of the highest plate portion 14 of a plurality of plate portions 14.The lower flange 22 has a truncated cone shape with an external diameter that increases from its lower end to its upper end. The external diameter at the upper end of the lower flange 22 is smaller than the lowest plate portion 14 of a plurality of plate portions 14. The upper end of the lower flange 22 is connected to a lower tapered portion 32 of the lowest plate portion 14. The lower end of the stem portion 11 is connected to a fixing pin 23 extending along the applicator axis O and having a circular column shape. The fixing pin 23 has a smaller external diameter than the stem portion 11 and is attached to a handle (not shown) of the applicator 1 by snapping. The handle is detachably attached to a container holding a cosmetic formula.The cosmetic formula contained in the container is an eyelash serum, for example.

[0029] The external diameter DI of the ball application portion 12 is between 2.0 mm and 5.0 mm, for example, and is larger than the external diameter of the upper end of the rod portion 11. The comb application portion 123 includes a plurality of plate portions 14 arranged along the applicator axis O. The plate portion 14 has a disc shape with a thickness Tl of 0.07 mm, for example, and the external diameters of the plate portions 14 increase from the highest plate portion 14 to the lowest plate portion 14 in a plurality of plate portions 14. In other words, the external diameter of a plate portion 14 is smaller than that of the adjacent plate portion 14 located on the lower side of a plate portion 14. The change in the external diameters of a plurality of plate portions 14 is adapted to the curve of the eyelids which are a targeted object.The external diameter D2 of the highest portion of plate 14 is 2.8 mm, for example, and the external diameter D3 of the lowest portion of plate 14 is 4.2 mm, for example.

[0030] The upper surface and the lower surface of the portion of plate 14 in a portion radially inwards from the outer circumference of the portion of Plate 14 is formed respectively with an upper tapered portion 31 and a lower tapered portion 32. The outer tapered portion 31 and the lower tapered portion 32 have circular ring shapes, and the inner circumferences of the upper tapered portion 31 and the lower tapered portion 32 are connected to the outer surface of the stem portion 11. The outer diameter of the upper tapered portion 31 decreases upwards from the plate portion 14, and the outer diameter of the lower tapered portion 32 decreases downwards from the plate portion 14. Thus, the lower tapered portion 32 of a plate portion 14 and the upper tapered portion 31 of an adjacent plate portion 14 located on the lower side of a plate portion 14 form a triangular groove.The groove allows for the efficient removal of chips generated during the manufacture of applicator 1 by a Swiss bar turning process.

[0031] The gap G1 between a portion of plate 14 and the adjacent portion of plate 14 located on the lower side of a portion of plate 14 is between 0.5 mm and 0.7 mm, for example, and the amount of radial outward projection of the portion of plate 14 relative to the external surface of the portion of rod 11 is between 0.2 mm and 0.8 mm, for example. The thickness T2 of the upper tapered portion 31 is between 0.1 mm and 0.4 mm, for example. The same applies to the thickness T3 of the lower tapered portion 32. The lower tapered portion 32 formed on a portion of plate 14 is spaced from the upper tapered portion 31 formed on the adjacent portion of plate 14 located on the lower side of a portion of plate 14, and the gap G2 between them is between 0.05 mm and 0.3 mm, for example.Furthermore, an angle 0 formed by the lower tapered portion 32 formed on a portion of plate 14 and the upper tapered portion 31 formed on the adjacent portion of plate 14 located on the lower side of a portion of plate 14 is between 80 degrees and 120 degrees, for example.

[0032] Furthermore, the lower tapered portion 32 formed on a plate portion 14 can be connected to the upper tapered portion 31 formed on the adjacent plate portion 14 located on the lower side of a plate portion 14. Moreover, the upper tapered portion 31 and the lower tapered portion may have different shapes unless the upper tapered portion 31 and the lower tapered portion 32 project radially outwards from the plate portion 14. In addition, the upper tapered portion 31 may have a different shape relative to the lower tapered portion 32. The lower tapered portion 32 formed on the lowest plate portion 14 of a plurality of plate portions 14 is connected to the lower flange portion 22.

[0033] Next, the use of the applicator 1 with such a configuration will be described. After detaching the handle of the applicator 1 from the container, the applicator 1 is The cosmetic formula is extracted from the container with the rod portion 11 attached to it. The gaps between the plate portions 14 serve as reservoirs to hold the cosmetic formula. The cosmetic formula attached to the rollerball applicator portion 12 is applied to the upper or lower eyelid, which are the target areas, by coming into contact with the rollerball applicator portion 12. The rollerball applicator portion 12 applies the cosmetic formula in a linear pattern by moving the applicator portion 12 along the upper or lower eyelid. Because the rollerball applicator portion 12 is made of metal, a cooling sensation is felt by the user when the applicator portion 12 comes into contact with the target area, allowing the user to feel that the applicator portion 12 is making contact with the target area.Furthermore, since the rollerball applicator 12 has a ball shape, it provides a gentle sensory experience to the targeted area, such as the eyelid. The cooling effect also helps to decongest the eye contour. Moreover, applying the cosmetic formula to the roots of the eyelashes using the rollerball applicator 12 enhances the effect of the cosmetic formula.

[0034] Furthermore, a cosmetic formula attached to the comb application portion 13 is applied to the eyelashes, which is a target object, by coming into contact with the comb application portion 13. The comb application portion 13 applies the cosmetic formula like a comb by positioning the eyelashes between the plate portions 14. Since the external diameters of the plate portions 14 increase from the upper end side to the lower end side of the stem portion 11, short eyelashes, which are located at the corners of an eye, have the cosmetic formula applied by means of some of the plate portions 14 of a group of plate portions 14 which have a relatively small diameter, while long eyelashes, which are located between the corners of an eye, have the cosmetic formula applied by means of some of the plate portions 14 of a group of plate portions 14 which have a relatively large external diameter.Furthermore, since the external diameter of the shank portion 11 increases from its upper end to its lower end, the distance between the outer circumferential edge of the plate portion 14 and the bottom of the space holding the cosmetic formula located between the plate portions 14 does not become excessively large. Thus, when the cosmetic formula is applied using some of the plate portions 14 from a group of plate portions 14 that have a relatively large external diameter, the cosmetic formula held in the space between the plate portions 14 is firmly applied to the eyelashes. Moreover, since the change in the external diameters of a plurality of plate portions 14 is adapted to the curve of the... For eyelids, the comb-like application portion 13 provides the user with a more secure feel when it comes into contact with the eyelid. The applicator 1 is used as described above to apply the cosmetic formula to the targeted area.

[0035] According to the applicator 1 with the above configuration, since the applicator 1 is made from a metal with high thermal conductivity, the applicator 1 can provide the user with a cooling sensation when the applicator 1 comes into contact with an eyelid, for example, so as to provide the user with the sensory feedback indicating that the applicator 1 is in contact with the eyelid. In particular, when the rollerball application portion 12 comes into contact with an eyelid, it is easy for the applicator 1 to provide the user with this sensory feedback, and the rollerball application portion 12 can provide a gentle sensory experience. Furthermore, by making the applicator 1 from aluminum, stainless steel, gold, silver, copper, or brass, the applicator 1 can significantly improve the sensory feedback of an eyelid.

[0036] Furthermore, since the cosmetic formula is applied to the eyelashes by means of the comb application portion 13, while the cosmetic formula is applied to an eyelid by means of the ball application portion 12, the operability of the applicator 1 for applying the cosmetic formula according to the targeted objects can be improved.In particular, since the external diameters of the plate portions 14 increase from the upper end side to the lower end side of the shank portion 11, short eyelashes, which are located at the corners of an eye, can have the cosmetic formula applied by means of some of the plate portions 14 from a group of plate portions 14 which have a relatively small diameter, while long eyelashes, which are located between the corners of an eye, can have the cosmetic formula applied by means of some of the plate portions 14 from a group of plate portions 14 which have a relatively large external diameter.Furthermore, since the external diameter of the stem portion 11 increases from its upper end to its lower end, the distance between the outer circumferential edge of the plate portion 14 and the bottom of the space holding the cosmetic formula located between the plate portions 14 does not become excessively large. Thus, when applying the cosmetic formula using some of the plate portions 14 from a group of plate portions 14 that have a relatively large external diameter, the cosmetic formula held in the space between the plate portions 14 is applied appropriately to the eyelashes. Moreover, the highest plate portion 14 of a plurality of plate portions 14 is prevented from unintentionally coming into contact with an eyelid when applying the cosmetic formula to the eyelid using the portion. ball application portion 12 so as to improve the operability of the applicator 1 by means of the ball application portion 12.

[0037] Moreover, by attaching the applicator 1 to the handle, the operability of the applicator 1 by means of the handle can be improved.

[0038] The inventions of this application are not limited to the embodiments described above, and various modifications of the embodiments described above may be made without departing from the concept of the inventions of this application. For example, in the above embodiment, the applicator may be formed from a metal other than the aforementioned metals. Furthermore, the applicator may be machined by processes other than the Swiss bar turning process. In addition, the applicator may be configured to apply a cosmetic formula other than eyelash serum. Although the round application portion is the rollerball application portion, the round application portion may have another shape, such as a circular cone with a rounded tip, for example.Although there is a gap between the plate portions configuring the comb application portion, the tapered portions of adjacent plate portions can be connected. Furthermore, plate portions can omit tapered portions. While the outside diameters of a group of plate portions forming the comb application portion increase from the upper end to the lower end of the shank portion, the outside diameters can increase from the lower end to the upper end of the shank portion. Moreover, it is possible that the outside diameters of a group of plate portions forming the comb application portion may not increase from one end to the other end of the shank portion unless the outside diameters change along the applicator axis.Furthermore, although the external diameter of the ball application portion is larger than that of the highest plate portion in a plurality of plate portions, the external diameter of the ball application portion may be equal to or smaller than that of the highest plate portion. Although the external diameter of the portion of the rod on which the comb application portion is provided increases from its upper end to its lower end, the external diameter of the portion of the rod on which the comb application portion is provided may be constant along the applicator axis. Moreover, although the rod is linear, it may be curved. Although the applicator includes the mounting pin attached to the handle, the applicator may include a handle integrated into the rod portion as a single piece of material.The size of each piece may differ from that of the embodiment above.
