Description

[Technical Field]

[0001] The present application relates to an application member for applying a cosmetic liquid such as eye shadow to an application target such as an eyelid, an application tool including such an application member, and a cosmetic tool including such an application tool. [Background technology]

[0002] BACKGROUND ART Conventionally, the application member disclosed in Patent Document 1 has been proposed as an application member for applying cosmetic liquid such as eye shadow to an application target such as an eyelid. This applicator includes a stem attached to the stem of the applicator and a head protruding from the distal end of the stem, the head including a concave first surface, a convex second surface opposite the first surface, and a peripheral edge. Such an applicator is configured by attaching the stem to the stem, and the applicator is removably attached to the neck of a container body containing a cosmetic liquid. When the applicator is to be applied, the concave first surface continues to hold the cosmetic liquid, and as a result, the cosmetic liquid on the convex second surface is wiped off by contact with a wiper disposed inside the container body when the applicator is withdrawn. The cosmetic liquid on the first surface is then first applied to an object by bringing the second surface into contact with the object. In addition to Patent Document 1, the application members disclosed in Patent Documents 2 to 7 are known as application members. [Prior art documents] [Patent documents]

[0004] However, these application members are required to apply cosmetic liquid in various situations. Therefore, an object of the present invention is to provide an applicator member, an applicator, and a cosmetic tool that can apply cosmetic liquid in a variety of situations. [Means for solving the problem]

[0005] The present invention employs the following means to solve the above problems: The applicator member of the present invention is an applicator member to be attached to a shaft member constituting an applicator and to apply a cosmetic liquid to an object to be applied, and includes a shaft portion attached to the shaft member and extending along the axis, and a head portion protruding distally from the distal end of the shaft portion, the head portion including a first application surface, a second application surface opposite the first application surface, and a peripheral portion, the second application surface being a curved surface protruding away from the axis, and the first application surface being flatter than the second application surface.

[0006] According to the present invention, the flatter first application surface can hold more cosmetic liquid than the second application surface, so a relatively large amount of cosmetic liquid can be applied to the application object by contacting the first application surface with the application object. If necessary, the cosmetic liquid applied to the application object can be spread and blurred by contacting the second application surface with the application object. Furthermore, if necessary, a line of cosmetic liquid can be drawn by contacting the peripheral portion with the application object. Therefore, cosmetic liquid can be applied to the application object in a variety of situations.

[0007] Furthermore, in the application member according to the present invention, the peripheral edge may be provided with a holding groove for holding the cosmetic liquid. According to the present invention, when the peripheral portion is brought into contact with an object to draw a line of cosmetic liquid, the cosmetic liquid held in the holding groove is supplied to the peripheral portion that comes into contact with the object to be applied. This prevents the line of cosmetic liquid from becoming blurred or broken. This allows the peripheral portion to be used to draw a smoother line of cosmetic liquid.

[0008] Furthermore, in the applicator member according to the present invention, the retention groove may extend across the distal end of the head. According to the present invention, the retention groove extends over the distal end of the head, thereby reducing the thickness of the distal end of the rim, thereby enabling a thinner line of cosmetic liquid to be drawn when the distal end of the rim is used to draw the line of cosmetic liquid.

[0009] Furthermore, in the applicator member according to the present invention, the peripheral edge may be provided with a pair of holding grooves on both sides. According to the present invention, as described above, the holding grooves are formed on the sides of the head, so that the thickness of the sides of the peripheral edge is reduced, thereby enabling a thinner line of cosmetic liquid to be drawn when the sides of the peripheral edge are used to draw a line of cosmetic liquid.

[0010] Furthermore, in the applicator member according to the present invention, a head axis along which the head extends may be inclined toward the second application surface with respect to the axis. According to the present invention, when an applicator having an application member attached thereto is pulled out from a container body containing cosmetic liquid, the cosmetic liquid adhering to the second application surface can be effectively wiped off by the container body.

[0011] Furthermore, in the applicator member according to the present invention, the width of the head at the distal end may narrow distally. According to the present invention, a thinner line of cosmetic liquid can be drawn using the distal end of the head. Furthermore, when the applicator having the applicator member attached thereto is attached to the container body after drawing the cosmetic liquid onto the application target, the applicator member can easily pass through the neck of the container body.

[0012] Furthermore, in the application member according to the present invention, the head portion may be formed symmetrically with respect to the axis. According to the present invention, the position of the applicator member can be changed from one position for applying a cosmetic liquid onto the right eyelid to another position for applying a cosmetic liquid onto the left eyelid without significantly changing the way the applicator to which the applicator member is attached is held, thus making the applicator more convenient.

[0013] Furthermore, an applicator according to the present invention includes the above-described applicator member and a shaft member attached to the applicator member. Furthermore, a cosmetic tool according to the present invention comprises the above-mentioned applicator and a container body containing a cosmetic liquid to which the applicator is removably attached. According to these inventions, as described above, a relatively large amount of cosmetic liquid can be applied to the target by contacting the first application surface with the target, and if necessary, the cosmetic liquid applied to the target can be spread and blurred by contacting the second application surface with the target. Furthermore, if necessary, a line of cosmetic liquid can be drawn by contacting the peripheral portion with the target. Therefore, cosmetic liquid can be applied to the target in a variety of situations. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, a first embodiment of an applicator member, an applicator tool, and a cosmetic tool according to the present invention will be described with reference to the drawings. In the drawings used in the following description, each element is shown to a corresponding scale for ease of understanding.

[0016] As shown in Figures 1 to 6, the applicator member 1 according to this embodiment is for applying a cosmetic liquid such as eye shadow to an application target such as the eyelids. The applicator member 1 is formed from a thermoplastic elastomer, and the surface of the applicator member 1, surrounded by a frame X shown in Figure 1, is flocked in order to apply the cosmetic liquid on the applicator member 1. The flock has, for example, a length preferably between 0.3 mm and 1.5 mm, more preferably between 0.7 mm and 1.2 mm, and a thickness of, for example, 1.7 dtex.

[0017] The applicator member 1 is attached to the distal end of the shaft member 11 of the applicator 10. The applicator 10 includes the applicator member 1, the shaft member 11, and a handle (not shown) attached to the proximal end of the shaft member 11. The cosmetic tool further includes the applicator 10 and a container body containing a cosmetic liquid, the applicator handle being snap-fitted to the neck of the container body. The handle of the applicator 10 can be removably attached to the neck of the container body in any suitable manner other than snap-fitting. Furthermore, a frustoconical wiper is disposed inside the container body, and this wiper comes into contact with the applicator member 1 when the applicator 10 is inserted into the container body and when the applicator 10 is withdrawn from the container body. Hereinafter, the direction away from the axial member 11 along the axis O along which the axial member 11 extends will be referred to as the distal direction, and the opposite direction will be referred to as the proximal direction.

[0018] The applicator 1 includes a cylindrical shaft 21 attached to the distal end of the shaft member 11, and a head 22 protruding from the distal end of the shaft 21. The shaft member 11 and the shaft 21 extend along an axis O, and the head 22 extends along a head axis O'. Shank 21 includes a cylindrical shaft body 31 extending along axis O, a cylindrical small-diameter section 32 having a diameter smaller than that of shaft body 31, and a connecting section 33 connecting shaft body 31 and small-diameter section 32, the outer diameter of which increases from its proximal side to its distal side. Shank 21 has a length L1 along axis O of, for example, 9.7 mm, and a length L2 of shaft 21 from the distal end of the flock-free portion of shaft body 31 to the proximal end of connecting section 33 of, for example, 6.5 mm.

[0019] The head 22 is a flat plate extending distally from the distal end of the shaft 21, and includes a substantially flat first application surface 41, a second application surface 42 opposite the first application surface 41, and a peripheral edge 43 extending around the outer periphery of the head 22. The head axis O' is inclined with respect to the axis O. That is, the head 22 protrudes from the distal end of the shaft 21 in a direction bending from the distal end of the shaft 21. The angle θ1 formed by the head axis O' and the axis O is, for example, 18 degrees.

[0020] Head 22 has a pentagonal shape in front view and includes a proximal portion 44 proximal to shaft 21 and a distal portion 45 disposed distally from proximal portion 44 . The proximal portion 44 has a trapezoidal shape in a front view, and the width of the proximal portion 44 in the lateral direction gradually increases from its proximal side toward its distal side. The width W1 at the distal end of the proximal portion 44, i.e., the proximal end of the distal portion 45, is, for example, preferably between 5 mm and 7 mm, more preferably between 5.2 mm and 6 mm. The distal portion 45 has a triangular shape in front view, and the width of the distal portion 45 in the lateral direction gradually decreases from its proximal side to its distal side. The length L3 of the distal portion 45 along the head axis O' is shorter than the length L4 of the proximal portion 44 along the head axis O'. The length L4 of the proximal portion 44 is, for example, preferably between 6 mm and 9 mm, more preferably between 8 mm and 9 mm, and the length L3 of the distal portion 45 along the head axis O' is, for example, preferably between 3 mm and 5 mm, more preferably between 4 mm and 4.5 mm. Furthermore, the length L5 of the head 22 along the axis O is, for example, preferably between 10 mm and 14 mm, more preferably between 10 mm and 13 mm.

[0021] The first application surface 41 is inclined at a proximal portion 44 in order to gradually approach the head axis O' from its proximal side to its distal side, and extends substantially parallel to the head axis O' at a distal portion 45. Furthermore, the first application surface 41 is convexly curved in order to slope laterally from its center toward its outer side toward the second application surface 42. Furthermore, the first application surface 41 is designed so as not to come into contact with the wiper disposed inside the container body when the applicator 10 is attached to the container body and when the applicator 10 is pulled out from the container body.

[0022] The second application surface 42 curves from its center toward its peripheral edge 43 to approach the first application surface 41. Therefore, the second application surface 42 has a curved surface that protrudes away from the head axis O'. Furthermore, the second application surface 42 is configured to come into contact with a wiper provided on the inside of the container body when the applicator 10 is attached to the container body and when the applicator 10 is removed from the container body. Therefore, any cosmetic liquid adhering to the second application surface 42 is completely wiped off by the wiper when the applicator 10 is pulled out of the container body. Furthermore, the distance D1 between the axis O and the portion of the second application surface 42 farthest from the axis O is, for example, preferably between 4.2 mm and 5 mm, and more preferably between 4.5 mm and 4.9 mm.

[0023] The peripheral edge 43 smoothly connects to the second application surface 42 and is formed with a retention groove 43A that extends almost all the way around the periphery of the peripheral edge 43, except for a proximal portion of the peripheral edge 43 that is proximal to the shaft 21. This makes the thickness of the portion of the peripheral edge 43 that comes into contact with the application target thinner than it would be without the retention groove 43A.

[0024] Next, a method for using the applicator member 1, the applicator 10, and the cosmetic tool will be described. First, the applicator 10 is withdrawn from the container body containing the cosmetic liquid. The cosmetic liquid is attached to the surface of the head 22 of the applicator member 1. When the applicator 10 is withdrawn from the container body, the second application surface 42 comes into contact with a wiper disposed inside the container body. Therefore, when the applicator 10 is withdrawn from the container body, the wiper wipes away the cosmetic liquid attached to the second application surface 42. Because the second application surface 42 is a curved surface, the second application surface 42 makes good contact with the wiper, and the cosmetic liquid attached to the second application surface 42 is wiped away well. Therefore, excess cosmetic liquid on the surface of the head 22 is wiped away. The cosmetic liquid is retained on the first application surface 41 and in the retaining groove portion 43A.

[0025] Next, the first application surface 41 comes into contact with the application target, such as the eyelid, and deposits the cosmetic liquid on the first application surface 41. Thereafter, the second application surface 42 comes into contact with the application target to which the cosmetic liquid is to be applied by the first application surface 41, and moves relative to the application target to spread the cosmetic liquid evenly over the application target. Furthermore, the second application surface 42 can spread and blur the cosmetic liquid.

[0026] Furthermore, only the distal end of the peripheral portion 43 comes into contact with the target and moves relative to the target, drawing a line of cosmetic liquid on the target. As the line of cosmetic liquid is drawn, the amount of cosmetic liquid adhering to the head 22 decreases. However, because the cosmetic liquid held within the holding groove 43A is supplied to the distal end of the peripheral portion 43, the line of cosmetic liquid is drawn without blurring or interruption. The same considerations apply to situations in which only the side portions of the peripheral portion 43 come into contact with the target and draw a line of cosmetic liquid. Since the holding groove 43A is formed around almost the entire periphery and the thickness of the portion of the peripheral edge 43 that comes into contact with the application target is reduced, a thinner line of cosmetic liquid can be drawn. The applicator member 1, the applicator 10 and the cosmetic tool are used in the manner described above.

[0027] As described above, with the application member 1, the application tool 10 including the application member 1, and the cosmetic tool including the application tool 10, a relatively large amount of cosmetic liquid can be applied to the application target by contacting the first application surface 41 with the application target, and if necessary, the cosmetic liquid applied to the application target can be spread and blurred by contacting the second application surface 42 with the application target. If necessary, a line of cosmetic liquid can be drawn by contacting the peripheral portion 43 with the application target. In this way, cosmetic liquid can be applied to the application target in a variety of situations. Furthermore, when the peripheral portion 43 is brought into contact with the object to be applied to draw a line of cosmetic liquid, the cosmetic liquid held within the holding groove portion 43A is supplied to the peripheral portion 43 that comes into contact with the object to be applied to, thereby preventing the line of cosmetic liquid from becoming blurred or interrupted, and therefore allowing the line of cosmetic liquid to be drawn smoothly using the peripheral portion 43. Furthermore, since the holding groove portion 43A is formed over the distal end of the head portion 22, the cosmetic liquid held within the holding groove portion 43A is supplied to the peripheral portion that comes into contact with the object to be applied, and when drawing a line of cosmetic liquid using the distal end of the peripheral portion 43, it is possible to draw a thinner line of cosmetic liquid. Furthermore, when the applicator 10 is withdrawn from the container body containing the cosmetic liquid, the cosmetic liquid adhering to the second application surface 42 can be effectively wiped off by a wiper provided inside the container body. Furthermore, because the width of the head 22 at its distal end narrows distally, the applicator member 1 can easily pass through the neck of the container body and, therefore, can also pass through the wiper when the applicator 10 is attached to the container body after drawing the cosmetic liquid onto the object to be applied. Furthermore, since the head 22 is formed symmetrically with respect to the head axis O', it is possible to change the position of the applicator member 1 from one state for applying cosmetic liquid onto the right eyelid to another state for applying cosmetic liquid onto the left eyelid without significantly changing the way the applicator 10 is held.

[0028] Next, a second embodiment of the applicator, applicator, and cosmetic tool according to the present invention will be described. In the following description, elements and objects similar to those of the applicator, applicator, and cosmetic tool according to the first embodiment will be omitted. 7 to 12, the head 51 of the applicator member 50 according to this embodiment is formed with a pair of retaining grooves 52A on the peripheral edge 52. The retaining grooves 52A are formed on both sides of the head axis O'.

[0029] The applicator member 50, applicator, and cosmetic device having the above-described structure achieve similar effects. However, in the applicator member 50 according to the second embodiment, the retention groove 52A does not extend to the distal end of the rim 52, and the thickness of the distal end of the rim 52 that contacts the application target is thicker than in the applicator member 1 according to the first embodiment. Thus, a thicker line of cosmetic lotion can be drawn using the distal end of the rim 52 compared to the sides of the rim 52.

[0030] The present invention is not limited to the above-described embodiments, and various modifications to the above-described embodiments can be made without departing from the inventive concept of the present invention. For example, although the application member in the above embodiment is for applying a cosmetic liquid such as eyeshadow to the eyelids, the application member may be for applying other cosmetic liquids such as eyeliner, lipstick, or lip gloss. The same applies to applicators and cosmetic devices. Although the first application surface has a slightly convex curved surface, the first application surface can have other shapes, such as a slightly concave shape or a flat shape, as long as the first application surface is flatter than the second application surface. That is, the first application surface can have various shapes as long as the first application surface can retain the cosmetic liquid after the applicator is withdrawn from the container body. The curved shape of the second application surface can also be appropriately changed. When the applicator is withdrawn from the container body, the second application surface can come into contact with the wiper, but the second application surface can not come into contact with the wiper. In this case, for example, the cosmetic liquid adhering to the second application surface can be wiped off by contacting the inner surface of the neck of the container body. Although the retention groove has a straight shape, the retention groove can have other shapes, such as a wave shape. Furthermore, the depth and width of the retention groove can be appropriately changed. Moreover, the retention groove does not have to be provided on the applicator member. As shown in Figures 13 and 14, for example, the applicator member 60 has a head 61 including a first applicator surface 41, a second applicator surface 42, and a peripheral portion 62 without a retention groove. The head is formed symmetrically about the head axis, but the head can be formed non-symmetrically about the head axis and can have other suitable shapes. The width of the distal end of the head tapers distally, and the width of the distal end of the head can be set appropriately. The head axis is inclined toward the second application surface relative to the axis, but the angle of the head axis relative to the axis can be appropriately changed. For example, the head axis can be inclined toward the first application surface or can be inclined laterally relative to the axis. Furthermore, the head axis can be parallel to the axis. In the first embodiment, the retention grooves are formed around most of the entire circumference, but they can extend less than most of the entire circumference, as long as they extend to the distal end of the head. Similarly, in the second embodiment, a pair of retention grooves are formed on both sides of the periphery, but multiple pairs of retention grooves can be formed, or the retention grooves can be formed on only one side of the periphery. Furthermore, the retention grooves can not extend to the distal end of the head, as long as they can supply cosmetic liquid to the portion of the periphery that comes into contact with the subject. Although the head has a pentagonal shape in front view, the head may have other shapes, such as a hexagonal shape or a triangular shape. Furthermore, the width of the head in the lateral direction may be wider than the width of the lateral shaft, but the width of the head in the lateral direction may be narrower than the width of the lateral shaft. Furthermore, the length of the distal portion along the head axis may be shorter than the length of the proximal portion along the head axis, but the length of the distal portion along the head axis may be longer than the length of the proximal portion along the head axis. The cosmetic liquid is not limited to a pure liquid, but can also be a mixture of solids such as powders and liquids. [Explanation of symbols]
