Description

  The present invention relates to a cosmetic applicator used for applying cosmetics to eyelashes or eyebrows.

  Conventionally, a liquid applicator having a brush portion in which brush hairs are radially implanted by inserting brush hairs between a pair of wires formed by bending one metal wire and folding it in this state. Is being considered. For example, Patent Document 1 has a large amount application brush portion in which a coating liquid holding groove extending in the vertical direction is formed on the outer surface of the brush hair, and a small amount application brush portion having no coating liquid holding groove at the tip. A liquid applicator is described. This document describes that by using this liquid applicator, a sufficiently thick coating liquid can be applied by a single coating operation, and the coating liquid can be applied to the details.

  Patent Document 2 describes that, in a mascara brush formed in an arc shape so as to follow the curve of the eyelid, the arc is set to have a radius of 13 mm to 25 mm in plan view. This document describes that according to this mascara brush, mascara can be easily applied to the eyelashes without taking time and effort.

  Further, in Patent Document 3, in a mascara applicator having a brush portion radially attached to a core member as a shaft portion, the core member is formed in an arc shape, and further, a fiber pile thinner than the brush hair is implanted at the tip of the brush portion. It is described. This document describes that according to this mascara applicator, the mascara treatment of the central part of the prominent eyelashes can be performed efficiently and curling up is easy.

  When the mascara applicator described in Patent Documents 1 and 2 is pulled out of the container containing the mascara coating solution, and the ironing operation is performed to move up and down to remove excess mascara in the vicinity of the opening or mouth of the container, The adhesion of the liquid to the brush part close to the grip part of the mascara applicator after exposure is not good, and a dark part and a thin part are seen, and the mascara application liquid tends to become uneven. Even at the tip of the brush portion, even if a squeezing operation that moves up and down to remove excess mascara coating liquid is performed, large liquid lumps tend to stick to the tip. This is thought to be due to insufficient liquid flow to the brush portion during the ironing operation.

  Using the mascara applicator with the mascara coating solution unevenly attached in this way, when the liquid is applied to the eyelashes, a large amount of liquid is attached to the tip, so it adheres to the eyelashes unevenly and creates a hair bundle. Cause. The inventors of the present invention have eyelashes, eye corners, and lower eyelash portions that are difficult to apply the coating solution, and the eye is short with eyelashes, and when a large amount of coating solution is attached at once, a hair bundle is formed on the eyelashes. We found the problem of deteriorating the aesthetic appearance. Furthermore, even if an attempt is made to correct the generated hair bundle, since a large amount of liquid is attached to the tip, partial correction cannot be easily performed, and the usability is greatly impaired.

  Also in the mascara applicator described in Patent Document 3, when the liquid is applied from the eyelashes to the corners of the eyelashes at once, the liquid tends to adhere unevenly to the eyelashes and the corners of the eyelashes. This is because the core member at the tip of the brush is made of a material different from the wire of the brush portion. As a result, the brush is inferior, and the tip of the brush does not reach the eyelashes, resulting in uneven coating of the liquid, so that the liquid can be applied only to the central part, and the aesthetics are impaired.

  As described above, in the mascara applicator described in Patent Document 3, it has been difficult to apply mascara cosmetics at once to most of the eyelashes extending from the front of the eye to the outer corner of the eye. Further, Patent Document 3 does not describe anything regarding the arrangement relationship between the brush part and the flocked brush part for applying the mascara cosmetic to the eyelashes at once.

  Therefore, this invention relates to the cosmetic applicator which can eliminate the fault which the prior art mentioned above has.

The present invention is a cosmetic applicator comprising a gripping part and an application part,
The application portion includes a shaft portion extending from the grip portion, a brush portion by brush hairs extending radially from the shaft portion, and a flocking portion at a tip opposite to the grip portion in the shaft portion,
The brush portion is formed by being wound spirally in a state where the brush hair is inserted between two metal wires,
The flocked portion is configured to include a tip wire portion made of a metal tip wire connected to the metal wire constituting the brush portion, and a fiber finer than the brush hair on the surface of the tip wire portion. And
The tip wire portion provides a cosmetic applicator having a wound portion formed by winding the tip wire a plurality of times.

  According to the present invention, for example, when used as a cosmetic applicator for mascara, the cosmetic material uniformly adheres to the entire brush portion of the applicator when pulled out from the container, and the cosmetic material further adheres to the tip of the brush portion. For example, it is possible to apply an appropriate amount of a cosmetic for mascara to eyelashes on the eye side, eyelashes on the outer corners, and lower eyelashes, which are short of eyelashes. As a result, generation of lumps and hair bundles on the eyelashes is suppressed, and unpainted portions are prevented. Furthermore, since the wire which comprises a brush part is continued to the hair transplant part, it is excellent in the followability of a brush part and a hair transplant part at the time of application | coating. Moreover, since the wire is wound at the tip, irregularities are formed on the surface of the flocked portion, the flocked hair can be adhered closely, and the cosmetic has excellent retention, so that it can be applied evenly to the eyelashes. In addition, since the wire is easy to process, it can be formed into a free shape according to the purpose, and even if it is used for a long period of time, the shape of the flocked portion does not collapse, and it always has the same appearance and It can be used with texture.

A screw portion 22 is provided on the outer peripheral surface of the mouth portion 23. The screw portion 22 can be screwed with a screw portion (not shown) provided on the inner peripheral surface of the grip portion 11 of the applicator 1 to be described later.

  The container 2 is provided with a flexible squeezing valve 21 having a squeezing hole 211 in the mouth 23 or in the vicinity of the mouth 23. Specifically, as shown in FIG. 1, the mouth portion 23 in the container 2 has an iron valve 21 in the vicinity thereof. The ironing valve 21 includes a funnel-like shape having a diameter reduced from the mouth 23 of the container 2 toward the bottom, and has a ironing hole 211 at the lower end in the axial direction (Y direction). The ironing hole 211 can freely pass through the connecting part 121, the brush part 13, and the flocked part 14 in the applicator 1 described later. The ironing hole 211 is formed in a substantially central portion in the radial direction (X direction) of the ironing valve 21 in a cross-sectional view of the container 2. The ironing hole 211 is a circular hole. Around this circular hole, one or more slits may be provided radially. However, the shape of the ironing hole 211 is not limited to this. The ironing hole 211 has a size that allows the brush portion 13 and the hair transplant portion 14 located on the lower end side of the applicator 1 to be inserted into the container 2 and extracted from the container 2. The squeezing valve 21 is used to moderately squeeze out an excessive amount of the cosmetic 3 adhering to the connecting part 121, the brush part 13, and the flocked part 14 of the applicator 1. For this purpose, the ironing valve 21 is made of an elastically deformable material such as rubber or resin. In FIG. 1, the squeezing valve 21 is located in the vicinity of the mouth portion 23, i.e., slightly downward from the mouth portion 23 in the axial direction (Y direction). Alternatively, the squeezing valve 21 may be arranged. The vicinity of the mouth part 23 of the container body 3 includes a part from a part slightly away from the mouth part 23 to the mouth part 23.

  As shown in FIG. 1, the applicator 1 can enter and exit the container 2 from the mouth portion 23 of the container 2 having the above-described configuration. The applicator 1 includes a grip portion 11 and an applicator 10. The application unit 10 includes a shaft portion 12 extending from the grip portion 11, a brush portion 13 using brush hairs extending radially from the shaft portion 12, and a flocking portion 14 positioned at the tip of the shaft portion 12 opposite to the grip portion 11. ing. Between the grip portion 11 and the brush portion 13, an elongated columnar connecting portion 121 is interposed. Thus, the applicator 1 has the brush part 13 and the flocked part 14 at the tip of the connecting part 121 fixed to the grip part 11. The grip portion 11 is a portion that is gripped with a finger during use. In the present embodiment, the grip portion 11 also serves as a lid that covers the mouth portion 23 of the container 2. The grip portion 11 is connected to the upper end portion of a rod-like connection portion 121 that extends in a straight line and parallel to the axial direction (Y direction). And the brush part 13 and the hair transplant part 14 are provided in the axial direction (Y direction) lower end part of the connection part 121. As shown in FIG. Hereinafter, the brush portion 13 and the flocked portion 14 will be described in detail. FIG. 2 is a side view of the applicator 1 of FIG. 1, and FIG. 3 is an enlarged side view of a main part of the applicator 1 of FIG.

  As shown in FIGS. 2 and 3, the brush portion 13 has a curved shape and is wound in a spiral shape with the bristles 132 inserted between two metal wires 131. It is formed by being implanted radially. Specifically, after folding one metal wire 131 into two, the bristle 132 is inserted between the two metal wires 131. Thereafter, by twisting the two metal wires 131 into which the bristle 132 is inserted, the elongated core body 133 is formed in the axial direction (Y direction), and the bristle 132 is held between the twists. The bristles 132 are regularly planted radially along the entire length of the elongated core 133. In this way, the brush portion 13 is formed. In the present embodiment, one metal wire 131 is folded back to be two, but two independent metal wires 131 may be used. The axial direction (Y direction) upper end side of the core 133 of the brush part 13 formed in this way is inserted and connected to the lower end of the connecting part 121 in the axial direction (Y direction). The connecting portion between the core body 133 and the connecting portion 121 of the brush portion 13 is fixed by embedding the core body 133 in the connecting portion 121 and connecting them.

  As the metal wire 131 forming the core body 133 of the brush portion 13, a wire made of stainless steel or the like can be used. The diameter of the stainless steel wire is preferably 0.1 mm or more and 2 mm or less, and more preferably 0.4 mm or more and 1 mm or less.

  As a material of the brush hair 132, synthetic resin fibers made of synthetic resin such as nylon, tetron, polypropylene, polyester, semi-synthetic fibers such as rayon, or natural fibers such as animal hair can be used. Further, the brush hair 132 may be solid fiber hair or hollow fiber hair. Further, the brush bristle 132 may have a cross-sectional shape such as a circle, an ellipse, or a polygon. When used for the brush hair 132, one type of hair having the same material, shape and cross section can be used alone, or a type of hair having at least one of different material, shape and cross section can be blended. Appropriate materials, shapes, and cross-sections of the brush bristles 132 are selected according to the application target site or the type of cosmetic 3 to be used. Of these, synthetic resin fibers made of synthetic resin such as nylon are preferable.

It is preferable that 3 or more and 85 or less brush hairs 132 are implanted for each winding of the metal wire 131 forming the core body 133, and more preferably 5 or more and 60 or less are implanted. preferable.

Further, the length of the brush hair 132 is preferably 1 mm or more and 15 mm or less, and more preferably 2 mm or more and 8 mm or less. The measurement of the length of the bristle 132 indicates the length from the tip to the end of the bristle 132 when wound around the metal wire 131.
In addition, in this embodiment, although the length from the core 133 surface of the bristle 132 is constant, length may differ. As an example in which the length of the bristle 132 is different, for example, the length of the bristle 132 from the surface of the core 133 is gradually shortened from the upper end side in the axial direction (Y direction) of the core 133 toward the rear end side. The length of the bristle 132 from the surface of the core 133 is gradually increased from the upper side to the lower side in the axial direction (Y direction) of the core body 133. For example, a form in which the length of the bristle 132 is irregularly different from the surface of the core body 133 is exemplified.

The application part 10 is formed in a shape in which the entire region from the brush part 13 to the flocked part 14 in the shaft part 12 is curved. Specifically, the outer surface of the entire region from the brush portion 13 to the hair transplantation portion 14 is curved along the core body 133, and the outer shape of the brush connecting the tips of the brush hairs 132 is cylindrical. Even when the brush portion 13 has a convex shape (a cylindrical shape in which the center swells) in which the maximum diameter of the brush portion of the brush portion 13 is the largest in the central region of the brush portion when viewed from the side. Even the concave shape (cylindrical shape with both ends bulging) that is the smallest in the center region of the flat shape (curved cylindrical shape with the same diameter as a whole), and the tapered cylindrical shape whose diameter decreases toward the tip However, a shape in which the maximum diameter of the brush portion of the brush portion 13 is maximized in the central region of the brush portion 13 is preferable in a side view of the state in which the brush portion 13 is most curved.
The maximum diameter of the brush portion of the brush portion 13 is preferably 1 mm or more and 15 mm or less, and more preferably 2 mm or more and 8 mm or less, when the brush portion 13 is most curved.
When viewed from the side of the most curved state of the brush part 13, the tip diameter on the side opposite to the grip part is preferably 1 mm or more and 15 mm or less, more preferably 2 mm or more and 8 mm or less, and 2 mm or more and 6 mm or less. Is more preferable.
The tip diameter of the brush portion 13 opposite to the gripping portion is preferably 9 mm or less, more preferably 7 mm or less, and even more preferably 2 mm or less, with respect to the maximum diameter of the cylinder of the brush portion 13. The tip diameter of the brush portion 13 opposite to the gripping portion may be a length equivalent to the maximum diameter of the cylinder of the brush portion 13.

  The brush portion 13 configured as described above has a curved formation as shown in FIGS. 2 and 3. That is, the brush part 13 is curved over the entire length. For example, from the viewpoint of conforming to the curve of the eyelid, the brush portion 13 preferably has an arcuate shape, more preferably has a radius of curvature of 10 mm or more and 300 mm or less, and is 13 mm or more and 200 mm or less. More preferably, it is more preferably 30 mm or more and 100 mm or less.

  As shown in FIG. 4, the flocked portion 14 provided at the lower end (tip) of the brush portion 13 in the axial direction (Y direction) is a tip wire made of a metal tip wire 161 connected to the metal wire 131 constituting the brush portion 13. A portion 16 is provided. As shown in FIG. 2, a plurality of fibers 141 are fixed to the surface of the tip wire portion 16 by electrostatic flocking. Further, as shown in FIG. 4, the tip wire portion 16 has a wound portion 162 formed by winding the tip wire 161 in a coil shape a plurality of times. The wound part 162 may have a hollow structure.

  As shown in FIG. 4, the tip wire 161 is composed of an extended portion in which a metal wire 131 constituting the brush portion 13 extends from the tip of the brush portion 13. Therefore, the tip wire 161 is composed of one or more wires that are the same as the metal wire 131. The tip wire portion 16 is formed by folding this one wire in half and winding the tip wire 161 in a coil shape so as to include the folded portion. In this way, the wire constituting the brush part is connected to the flocked part, so that the followability of the brush part and the flocked part at the time of application is excellent, and the wire is wound at the tip, so the flocked Since it can be attached and has excellent retention of cosmetics, it can be applied evenly to the eyelashes. Moreover, since the wire is easy to process, it is possible to create a free shape according to the purpose, and even if it is used for a long period of time, the shape of the flocked portion is not likely to collapse, and it will be used with the same appearance and texture as a new one forever. It is possible.

  As shown in FIG. 4, the tip wire portion 16 is formed by winding the tip wire 161 such that a loop surface defined by one turn of the tip wire 161 is substantially orthogonal to the extending direction of the brush portion 13. The wound portion 162 is provided. The tip wire portion 16 is formed by winding the tip wire 161 constituting the winding portion 162 so that no gap is formed between the tip wire 161 adjacent thereto. Since the tip wire portion 16 has such a structure, the fibers 141 can be densely electrostatically implanted in the tip wire portion 16. As a result, the advantageous effects produced by the flocked portion 14 can be made more remarkable. The term “substantially orthogonal” means that the loop surface and the extending direction of the brush portion 13 intersect within a range of 90 ° ± 10 °.

  FIG. 5 shows another embodiment of the tip wire portion 16. The tip wire portion 16 shown in the figure is different from the embodiment shown in FIG. 4 in the direction of the loop surface defined by one turn of the tip wire 161. Specifically, the tip wire portion 16 shown in FIG. 5 is wound so that the loop surface defined by one turn of the tip wire 161 is substantially parallel to the extending direction of the brush portion 13. The wound portion 162 is formed. The term “substantially parallel” means that the loop surface and the direction in which the brush portion 13 extends are completely parallel and that they intersect each other within a range of ± 10 degrees.

  In order to form the flocked portion 14 by electrostatically flocking the tip wire portion 16 shown in FIGS. 4 and 5, after applying an adhesive to the tip wire portion 16, the fibers 141 are electrostatically flocked by a known method. do it.

  As the material of the fibers 141 constituting the flocked portion 14, a synthetic resin fiber made of a synthetic resin such as nylon, polypropylene, polyester, polybutylene terephthalate, a semi-synthetic fiber such as rayon, or a natural fiber such as animal hair is used. Can do. As the material of the fiber 141, an appropriate material is selected according to the application target part or the type of the cosmetic 3 to be used. Of these, synthetic resin fibers such as nylon and semi-synthetic fibers such as rayon are preferable.

The fiber 141 of the flocked portion 14 includes a suitable amount of the cosmetic 3, suppresses the occurrence of lumps and hair bundles in the eyelashes of the eyelashes, the corners of the eyes, and the lower eyelashes, and is applied uniformly. That is, the existence number per unit area) is preferably higher than the existence density of the brush bristles 132 of the brush part 13, and preferably more than 1 and 20000 times the density of the bristles 132 of the brush part 13, More preferably, the density is 2 to 2000 times the density of the brush bristles 132 of the brush portion 13. Specifically, the density of the fibers 141 in the flocked portion 14 is preferably 1 / mm ^{2 to} 10,000 / mm ² , more preferably 30 / mm ^{2 to} 5000 / mm ² . The density of the brush hairs 132 in the brush portion 13 is preferably 0.1 / mm ² or more and 100 / mm ² or less, more preferably 1 / mm ² or more and 30 / mm ² or less, and still more preferably. 3 / mm ² or more and 25 / mm ² or less is preferable.

  The density of the brush hairs 132 in the brush portion 13 can be measured as the number of brush hairs per unit area of the wire portion. On the other hand, the existence density of the fibers 141 of the hair transplantation part 14 can be measured like the number of the fiber transplantation fibers per unit area.

The thickness of the fibers 141 of the flocked portion 14 is preferably 1 μm or more and 29 μm or less, and more preferably 7 μm or more and 24 μm or less.

More preferably, it is 0.5 mm or more and 4 mm or less. In addition, in this embodiment, although the length from the surface of the base part for flocking of the fiber 141 is constant, length may differ.
The fibers in the flocked part may be manufactured by electrostatic flocking so that the fiber length is the same, but after electrostatically flocking the longer fibers, trimming is performed to adjust the length of the fibers. Also good.

  As shown in FIG. 3, the cosmetic applicator 1 configured as described above connects the tips of the radial brush hairs 132 located in the inner portion, as viewed from the side, in a state where the brush portion 13 is most curved. The outer shape (outer peripheral edge) having the maximum diameter passing through the shaft portion 12 of the flocked portion 14 is disposed at the tip along the extended line of the inner virtual curve IL1 formed in step (1). Accordingly, when the cosmetic applicator 1 is pulled out of the container 2 containing the cosmetic 3 and the squeezing operation is performed to remove the excess cosmetic 3 and move up and down, the flocked portion is moved from the brush portion 13 close to the grip portion 11. An appropriate amount can be stored up to 14. Furthermore, when it is applied to the eyelashes, it can be applied uniformly from the eyelashes to the corners of the eyelashes at a time, and the occurrence of lumps and hair bundles of the cosmetic 3 on the eyelashes can be suppressed. The term “along the extension line” means that the outer diameter (outer peripheral edge) of the maximum diameter of the flocked portion 14 is within a range from the outer side 1 mm to the inner side 1 mm on the extension line.

  Further, when drawing the inner virtual curve IL1 formed by connecting the tips of the bristles 132, when the length of the bristles 132 from the surface of the core 133 is constant as in this embodiment, In the case where the length of the bristle 132 from the surface of the core body 133 gradually decreases or gradually increases from the upper end side in the axial direction (Y direction) in the body 133 to the lower end side, The inner virtual curve IL1 can be drawn by connecting the tips of the brush bristles 132 of each other. When the length of the bristle 132 from the surface of the core 133 is irregularly different, 20 brush hairs 132 are randomly extracted, the average length is obtained therefrom, and the brush having the obtained average length is obtained. The inner virtual curve IL1 can be drawn by connecting the tips of the virtual brush bristles 132 with the bristles 132 as a reference.

  In a side view of the state in which the application part 10 is most curved, a curved shape (cylindrical shape) by the outer diameter of the brush connecting the maximum diameter passing through the shaft part 12 of the flocked part 14 and the tip of the brush hair 132 of the brush part 13 ) In the virtual three-dimensional three-dimensional columnar structure, the ratio of the tip diameter opposite to the gripping portion 11 (maximum diameter of the flocked portion 14 / tip diameter of the brush portion 13) is preferably 0.5 or more and 3 or less, 0.6 or more and 1.4 or less are more preferable, 0.7 or more and 1.2 or less are still more preferable, and 0.8 or more and 1.1 or less are still more preferable. Accordingly, when the cosmetic applicator 1 is pulled out of the container 2 containing the cosmetic 3 and the squeezing operation is performed to remove the excess cosmetic 3 and move up and down, the flocked portion is moved from the brush portion 13 close to the grip portion 11. Up to 14, an appropriate amount of the cosmetic 3 can be stored almost uniformly, and when the cosmetic 3 is applied to the eyelashes, it can be applied uniformly from the eyelashes to the corners of the eyelashes at once. The occurrence of lumps and hair bundles can be suppressed, and unpainted parts can be prevented.

  In a side view of the state in which the application part 10 is most curved, a curved shape (cylindrical shape) by the outer diameter of the brush connecting the maximum diameter passing through the shaft part 12 of the flocked part 14 and the tip of the brush hair 132 of the brush part 13 ) In the virtual three-dimensional solid cylindrical structure (maximum diameter of the flocked portion 14 / maximum diameter of the brush portion 13) is preferably 0.5 or more and 1.5 or less, and preferably 0.5 or more and 1.3. The following is more preferable, 0.6 to 1.2 is further preferable, and 0.8 to 1.1 is further more preferable. Accordingly, when the cosmetic applicator 1 is pulled out of the container 2 containing the cosmetic 3 and the squeezing operation is performed to remove the excess cosmetic 3 and move up and down, the flocked portion is moved from the brush portion 13 close to the grip portion 11. Up to 14, an appropriate amount of the cosmetic 3 can be retained almost uniformly, and when the cosmetic 3 is applied to the eyelashes, it can be applied uniformly from the eyelashes to the corners of the eyelashes at once. The occurrence of lumps and hair bundles can be suppressed, and unpainted parts can be prevented.

Examples of the shape of the flocked portion 14 include a shape arranged on the lower side (tip) in the axial direction (Y direction) along the extension line of the inner virtual curve IL1. For example, an egg shape or a bowl shape having a maximum width downward in the axial direction (Y direction) as shown in FIG. 3, a spherical shape having a maximum width in the center of the axial direction (Y direction) as shown in FIG. In addition to the inverted egg shape and the inverted saddle shape having the maximum width in the axial direction (Y direction) upward as shown in FIG. 4, it may be a polygonal shape, a design pattern shape, or the like.
3 and the inverted ridge-shaped flocked portion 14 shown in FIG. 7 are elongated in the axial direction (Y direction), and therefore, the extension line of the inner virtual curve IL1 is a line. The brush part 13 to the flocked part 14 of the cosmetic applicator 1 can be applied at once from the eye corners to the eyes of the eyelashes in a tightly fitted state. Furthermore, in the case of the eyelash shape shown in FIG. 3, application to the lower eyelashes is facilitated. Further, in the case of the inverted saddle shape shown in FIG. 7, the flocked portion is thin, so that the field of view is not obstructed at the time of application, and it can be finely applied to the eyes and the corners of the eyes that are difficult to apply.

  Specifically, an egg shape (an eagle shape) having a maximum width toward the lower side in the axial direction (Y direction) shown in FIG. 3 will be described in detail with reference to FIG. As shown in FIG. 8, “the egg shape having the maximum width in the axial direction (Y direction) downward (an eagle shape)” is an axial direction in which the tips of the plurality of fibers 141 of the flocked portion 14 are connected ( (Y direction) and a virtual true spherical IS that surrounds the long spherical shape through the longest part in the long spherical shape, the position of the center of gravity of the virtual spherical IS is It means a spherical shape that is closer to the gripping part 11 than the position of the center of gravity of the long spherical shape. Further, an inverted egg shape (inverted saddle shape) having a maximum width toward the upper side in the axial direction (Y direction) shown in FIG. 7 will be described in detail with reference to FIG. “An inverted egg shape having a maximum width toward the upper side in the axial direction (Y direction) (an inverted saddle shape)” is an axis connecting the tips of a plurality of fibers 141 of the flocked portion 14, as shown in FIG. When drawing a spherical shape that is long in the direction (Y direction) and a virtual spherical shape IS that surrounds the long spherical shape through the longest part of the long spherical shape, the position of the center of gravity of the long spherical shape is It means a spherical shape that is closer to the grip portion 11 than the position of the center of gravity of the virtual true spherical IS. Note that the spherical shape having the maximum width in the center in the axial direction (Y direction) shown in FIG. 6 means a spherical shape in which the position of the center of gravity of the spherical shape coincides with the position of the center of gravity of the virtual true spherical IS.

The shape of the flocked portion 14 can be arbitrarily controlled according to the shape of the tip wire portion described above. Specifically, a tip having a desired three-dimensional shape is obtained by adjusting the shape of the loop and the size of the loop each time the tip wire is wound into a coil shape a plurality of times to form a wound portion. A wire part can be formed. Examples of the shape of the loop include a circle, an ellipse, an oval, a bowl, a triangle, and a quadrangle. By combining various large and small loops of these shapes, it is possible to form a wound portion that is the basis of the flocked portion 14 having the shape shown in each of the above-described drawings.
Furthermore, the shape of the flocked portion 14 is preferably a block shape, and may be a rotating body or a non-rotating body. Examples of the non-rotating body include a polyhedron such as a triangular pyramid, a quadrangular pyramid, a hexahedron, and an octahedron, and an indefinite shape having no specific shape. Especially, it is preferable that it is a rotary body shape from the point of application | coating at a time in the state fit closely from the eye corner of eyelashes to the top of the eye. The rotator shape referred to here is a shape obtained by rotating about the virtual axis with the line symmetric plane center line of the line symmetric virtual plane shape as the virtual axis. Examples of the axisymmetric virtual plane include a circle, an ellipse, a bell shape, a saddle shape, a triangle with a rounded R shape, a quadrangle, a track shape, and the like, and the rotating body is preferably formed of a curved surface.

  In order to form the wound part in the tip wire part, a known method may be adopted as appropriate. As such a method, for example, a machine capable of three-dimensionally processing a wire such as a wire bending machine or a wire forming machine equipped with computer numerical control can be used.

  As shown in FIG. 3, the ratio (m / n) of the total length (m) of the flocked portion 14 to the total width (n) of the flocked portion 14 is as viewed from the side when the brush portion 13 is most curved. When the cosmetic applicator 1 is pulled out from the container 2 containing the hair, and the ironing operation is performed to move up and down to remove the excess cosmetic 3, the appropriate amount of cosmetic 3 from the brush portion 13 close to the grip portion 11 to the flocked portion 14 is obtained. Can be stored. Further, from the viewpoint of ease of application to eyelashes, it is preferably 0.5 or more and 10 or less, and more preferably 1 or more and 3.5 or less.

Specifically, the total length (p) of the brush portion 13 is preferably 3 mm or greater and 35 mm or less, and more preferably 15 mm or greater and 30 mm or less. Here, the total length (p) of the brush portion 13 means not the shortest distance between the upper and lower ends in the axial direction (Y direction) but the actual length of the long and thin curved core 133.

  Furthermore, as shown in FIG. 3, in a side view of the state in which the brush portion 13 is most curved, the total value (p + m) of the total length (m) of the flocked portion 14 and the total length (p) of the brush portion 13 is From the viewpoint that the cosmetic 3 can be applied to the eyelashes at a time, it is preferably 5 mm or more and 40 mm or less, and more preferably 20 mm or more and 35 mm or less.

As shown in FIGS. 2 and 3, the cosmetic applicator 1 of the present embodiment has a gap portion 15 between the outer shape of the brush connecting the tips of the brush hairs 132 of the brush portion 13 and the outer shape of the flocked portion 14. Have That is, the cosmetic applicator 1 has a gap portion 15 that is cut out in the axial direction of the brush portion 13 at the boundary between the brush portion 13 and the flocked portion 14. Specifically, the gap portion 15 is brushed from the surface of the brush bristle 132 at the lowermost end in the axial direction (Y direction) of the brush portion 13 and the base for flocking on the upper end side in the axial direction (Y direction) of the flocked portion 14. It is formed in a state of being cut out in the direction of the core 133 of the brush portion 13 over the entire circumferential direction between the tips of the plurality of fibers 141 erected toward the portion 13 side (see FIG. 10). The void portion 15 suppresses the occurrence of liquid fouling in the flocked portion 14 when the cosmetic applicator 1 is pulled out of the container 2 containing the cosmetic material 3 and the squeezing operation is performed to remove the excess cosmetic material 3 and move up and down. Therefore, from the viewpoint of storing an appropriate amount of cosmetic 3, the volume is preferably 0.1% or more and 100% or less of the volume of the flocked portion 14, and 1% or more and 80% or less of the volume of the flocked portion 14. It is more preferable that 2% or more and 50% or less of the volume of the flocked portion 14 is more preferable. The volume of the air gap 15 in particular is preferably 0.1 mm ³ or more 1500 mm ³ or less, more preferably 0.5 mm ³ or more 600 mm ³ or less, more preferably 1 mm ³ or more 50 mm ³ or less.
Here, the volume of the flocked portion 14 is a value obtained from a virtual three-dimensional shape formed by the widest outer periphery of the flocked portion 14, as shown in FIG. Further, as shown in FIG. 10, the volume of the gap portion 15 is such that the tip of the brush hair 132 on the lowermost side in the axial direction (Y direction) of the brush portion 13 and the portion located at the widest width of the flocked portion 14 Is a value obtained from a virtual three-dimensional solid cylindrical structure portion that is assumed by extending a line connecting the two points all around the axis center of the brush portion 13.

  Further, as shown in FIG. 3, the cosmetic applicator 1 is an outer side formed by connecting the tips of the radial brush hairs 132 located on the outer side when the state in which the brush portion 13 is most curved is viewed from the side. An outer shape (outer peripheral edge) having a maximum diameter passing through the shaft portion 12 of the flocked portion 14 is disposed along the extended line of the virtual curve IL2. This makes it possible to apply mascara to most of the eyelashes extending from the front of the eye to the outer corner of the eye. The term “along the extension line” means that the outermost outer diameter (outer circumference) of the flocked portion 14 is within a range from the outer side 1 mm to the inner side 1 mm on the extension line.

The effect at the time of using the cosmetics applicator 100 provided with the cosmetic applicator 1 of embodiment of this invention mentioned above is demonstrated.
As shown in FIG. 1, when the cosmetic applicator 1 having the above configuration is pulled out from the container 2 constituting the cosmetic applicator 100, the cosmetic applicator 1 of the cosmetic applicator 1 is caused by the ironing holes 211 of the ironing valve 21. Excess cosmetic 3 adhering to the shaft portion 12, the brush portion 13, and the flocked portion 14 is rubbed off. In that case, the application part 10 of the cosmetic applicator 1 is formed in the shape where the whole area | region from the brush part 13 in the axial part 12 to the hair transplant part 14 was curving, and the cosmetics applicator 1 has the brush part 13 in it. Since the hair transplantation part 14 is arranged along the extended line of the inner virtual curve IL1 at the lower end (tip) in the axial direction (Y direction) of the brush part 13, the axial direction (Y direction) of the brush part 13 It is difficult for the cosmetic 3 to stick to the lower end (front end) of the material, and an appropriate amount of the cosmetic 3 is held by the brush portion 13 and the flocked portion 14. In particular, the cosmetic applicator 1 of the present embodiment has a gap portion 15 at the boundary between the brush portion 13 and the flocked portion 14 as shown in FIGS. 2 and 3. When excess cosmetic material 3 is rubbed off by 211, the excess cosmetic material 3 can be held, and by performing a squeezing operation to move the cosmetic applicator 1 up and down, an appropriate amount of the cosmetic material 3 is transferred to the brush portion 13 and the flocking. Part 14 is held.

  FIG. 11A and FIG. 11B show examples of the usage state of the cosmetic applicator 1 of the present embodiment. Fig.11 (a) and FIG.11 (b) have shown the state which applies the cosmetics 3 for mascara to eyelashes as an application | coating object site | part. As described above, when the cosmetic applicator 1 is pulled out from the container 2 constituting the cosmetic applicator 100, an appropriate amount of the cosmetic 3 is held on the brush portion 13 and the flocked portion 14. Therefore, the user of the cosmetic applicator 1 uses not only the central part of the eyelashes but also many short eyelashes, as shown in FIG. An appropriate amount of cosmetic 3 for mascara can be applied to the eyelashes on the eye side. Moreover, as shown in FIG.11 (b), using the flocked part 14 with which the appropriate amount of cosmetics 3 were hold | maintained, the appropriate amount of the cosmetics 3 for mascara can be applied also to the eyelashes of the eyelid side.

  Further, in the cosmetic applicator 1 of the present embodiment, as shown in FIG. 3, the entire area from the brush portion 13 to the flocked portion 14 of the shaft portion 12 of the application portion 10 is curved. Therefore, as shown in FIG. 11A, the user of the cosmetic applicator 1 places the brush portion 13 and the flocked hair at the base of most of the plurality of eyelashes extending from the eye front side to the eye corner side of the curled eyelid. Since the part 14 can be closely contacted and applied without gaps, it can be applied uniformly at a time without unevenness on the eyelashes. In addition, the appearance of mascara and hair bundles on the eyelashes can be suppressed, and a finish with excellent aesthetics can be obtained. Further, the flocked portion 14 is unlikely to hit the user's nose, the field of view is difficult to block, and the operability is improved. Further, even when the use is stopped and the cosmetic applicator 1 is stored in the container 2, the entire area from the brush part to the flocked part has a curved shape. Can be stored smoothly without having to start over by simply holding the grip portion 11.

  Further, the user of the cosmetic applicator 1 moves the cosmetic applicator 1 from the state shown in FIG. 11A to the tip side of the eyelashes along the eyelashes, so that the eyelid side extends from the eye side to the eye corner side. The mascara cosmetic 3 can be applied to most of the plurality of eyelashes at a time. In particular, the cosmetic applicator 1 of the present embodiment has a gap portion 15 at the boundary between the brush portion 13 and the flocked portion 14 as shown in FIGS. Here, in the gap portion 15, the extending direction of the brush hair 132 at the lowermost end in the axial direction (Y direction) of the brush portion 13 and the surface of the base for flocking on the upper end side in the axial direction (Y direction) of the flocked portion 14. This is different from the extending direction of the fibers 141 standing from the side toward the brush part 13 side. Therefore, when the cosmetic applicator 1 is moved along the eyelashes toward the tip side of the eyelashes, the eyelashes are easily caught and scooped up, and the operability is improved.

  FIG. 12 shows another embodiment of the cosmetic applicator of the present invention. The cosmetic applicator 1 in the form shown in the figure is different from the cosmetic applicator described so far in that the brush portion 13 is not curved but linear in the same direction as the connecting portion 121 extends. It extends. About the point other than this, it has the same structure as embodiment described so far.

The cosmetic applicator of the present invention is not limited to the cosmetic applicator 1 of the present embodiment described above, and can be appropriately changed.
For example, the cosmetic applicator 1 described above is a mascara cosmetic applicator as shown in FIGS. 11A and 11B, using a mascara cosmetic as the cosmetic 3. Alternatively, an eyebrow cosmetic applicator may be used as the cosmetic 3 using eyebrow cosmetics and applying the eyebrow as the application target site. Furthermore, a cosmetic applicator for eyelashes or eyebrows may be used as the cosmetic 3 using eyelash / eyebrows essence and applying the eyelashes / eyebrows to the application target site.

  Moreover, the cosmetic applicator 1 of this embodiment is the space | gap part 15 notched in the axial direction of the brush part 13 in the boundary of the brush part 13 and the flocking part 14, as shown in FIG.2 and FIG.3. However, the gap portion 15 may not be provided.

  Furthermore, in the present embodiment, the tip wire 161 constituting the tip wire portion 16 is integrated with the metal wire 131 constituting the brush portion 13, but instead, the tip wire portion 16 is replaced with the tip wire portion 16. It is also possible to use a separate wire as the tip wire 161 that constitutes 16 and the metal wire 131 that constitutes the brush portion 13, and the two wires are coupled by a predetermined coupling means so that they are connected. By doing so, the tip wire 161 thinner than the metal wire 131 can be used, and the degree of freedom in designing the shape and size of the tip wire portion 16 composed of the tip wire 161 is further increased.
