It is often desired that the cosmetic applicator be capable of applying a large amount of cosmetics at one time and capable of delicate application such as blurring and fine application. This is widely demanded for many cosmetic applicators, but is particularly strongly demanded for cosmetic applicators such as those mentioned above because of the limited size of the application part. There is. In addition, the spatula-shaped application part can easily apply cosmetics by elastically deforming so as to follow the shape of the application target part such as lips, but on the other hand, it is easy to deform and lacks a sense of stability during use. To be

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cosmetic applicator that can apply a large amount of cosmetics at a time and can be applied delicately, and that provides a stable usability. And

The cosmetic applicator according to the present invention,
A cosmetic applicator having a rod-shaped gripping part to be gripped by a user, and an applying part attached to the tip of this gripping part to which a cosmetic is applied,
The coating part has a shape in which a substantially spindle-shaped member is cut in the middle by a surface inclined with respect to the longitudinal direction of the member,
An inclined surface portion including the surface in the coating portion extends in a region that extends from the portion including the maximum diameter portion of the substantially spindle-shaped member to the tip side,
It is characterized by that.

It should be noted that "to be gripped by the user" includes not only being directly gripped by the user but also indirectly gripping through the above-described cap or the like. Further, the above-mentioned "the inclined surface portion spreads to the front end side" means that the coating portion spreads to the side opposite to the grip portion. Further, the above-mentioned "expanded from the portion including the maximum diameter portion to the tip side" means that the inclined surface portion just extends from the maximum diameter portion to the tip side, and that the tip portion is extended from the grip portion side from the maximum diameter portion. It also includes spreading to the side.

In the cosmetic applicator of the present invention having the above configuration, at least a part of the application part may be flocked.

Further, in the cosmetic applicator of the present invention, it is desirable that the cosmetic to be applied, that is, the cosmetic to be attached to the application part, is configured as a lip cosmetic such as lipstick or lip gloss.

Further, in the cosmetic applicator of the present invention, the inclined surface portion may be a flat surface, or may be a concave surface or a convex surface as a whole. Then, a partial concave portion or a convex portion may be formed in such an inclined surface portion.

Further, it is desirable that the tip end portion of the inclined surface portion be chamfered.

The angle of inclination of the surface for cutting the substantially spindle-shaped member, that is, the angle of inclination with respect to the longitudinal direction of the member is generally about 5° to 60°, preferably 10° to 50°, and more preferably It is about 20° to 40°.

On the other hand, it is desirable that the grip portion has a shape having a portion whose cross-sectional area gradually decreases toward the coating portion. In the case of having such a portion, the grip portion is formed with a flange portion that projects radially outward on the rear end side of the grip portion with respect to the portion where the cross-sectional area gradually decreases and the cross-sectional area becomes maximum. May be. The above "rear end side of the gripping portion" means that the tip end of the gripping portion, that is, the end portion side opposite to the end portion to which the coating portion is attached.

In the cosmetic applicator of the present invention, the application part has a shape in which a substantially spindle-shaped member is cut in the middle by a surface inclined with respect to the longitudinal direction of the member, and the surface of the application part is Since the included inclined surface portion extends in a region including the maximum diameter portion of the substantially spindle-shaped member and extending from the portion toward the tip side, a large amount of cosmetic can be attached to the expanded inclined surface portion. .. Therefore, the user can apply a large amount of cosmetics to the lips etc. at a time by using this inclined surface portion. Further, if the application portion has the above-described shape, the portion that contacts the back side of the inclined surface portion, that is, the peripheral surface of the substantially spindle-shaped member is a curved surface like a finger. Therefore, the user can apply the cosmetic material to the curved surface and delicately apply the cosmetic material by thinly stretching it with a finger. Further, when the coating portion has the above-described shape, the boundary portion between the peripheral surface and the inclined surface portion of the substantially spindle-shaped member often has a shape like a ridgeline of a mountain. Therefore, the user can attach a small amount of the cosmetic to the narrow boundary portion and delicately apply the cosmetic to the lips and the like. The inclined surface portion serving as the application surface is formed on a part of the member that is essentially in the shape of a spindle, but this member is not easily deformed during application of the cosmetic, so that a stable usability can be obtained. it can.

The figure which shows the front shape and side shape of the cosmetics applicator by 1st Embodiment of this invention. FIG. 3 is a perspective view showing a state in which the cosmetic applicator is attached to a support member. A side view showing a state in which the cosmetic applicator is attached to a cap of a cosmetic container. Partially broken side view showing the state when the above-mentioned cosmetic applicator is in use The figure which shows the front shape and side shape of the cosmetics applicator by 2nd Embodiment of this invention.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a cosmetic applicator 1 according to a first embodiment of the present invention, in which (a) shows its front shape and (b) shows its side shape. Further, the perspective view of FIG. 2 shows a state where the cosmetic applicator 1 is attached to the support member 10 as one usage mode of the cosmetic applicator 1. As shown in FIGS. 1 and 2, the cosmetic applicator 1 includes a stick-shaped grip portion 20A that is gripped by a user, and an application portion 20B that is attached to the tip of the grip portion 20A and onto which cosmetics are attached. Have and. The grip portion 20A and the coating portion 20B may be formed separately, but generally they are integrally formed using resin. As the resin in that case, for example, an elastomer resin such as a thermoplastic elastomer resin can be preferably used.

The coating portion 20B has a shape in which a substantially spindle-shaped member 20 (hereinafter referred to as a coating member) is cut in the middle by a surface inclined with respect to the longitudinal direction of the member. In FIG. 1, in order to clearly show the above-mentioned “substantially spindle-shaped”, in the side view of (b), a portion assumed to be cut is shown by a broken line. The "cut shape" is merely a shape, and may be the shape shown in the figure by resin molding or the like. Alternatively, of course, a member having a substantially spindle shape may be obtained once, and then the member may be actually cut into the illustrated shape.

An inclined surface portion 21 including the above-mentioned surface (a surface assumed to be cut) is formed in the coating portion 20B. The inclined surface portion 21 includes the maximum-diameter portion of the approximately spindle-shaped coating member 20, and extends from the portion to a tip end side (a side opposite to the grip portion 20A and the lower side in the drawing). The maximum diameter portion is a portion having the maximum diameter indicated by arrow D in the side view of FIG.

The maximum diameter (diameter) D is generally set to about 3 mm to 5 mm, but is not limited thereto. On the other hand, the length of the coating portion 20B is generally about 10 mm to 15 mm, but the length is not limited thereto. Further, the angle of the “inclination” is indicated by θ in FIG. The inclination angle θ is, for example, within the range of 5° to 60°, preferably within the range of 10° to 50°, and more preferably within the range of 20° to 40°. In the present embodiment, θ=30° as an example. The coating member 20 may have any shape as long as it forms a part of a substantially spindle shape, and is not limited to a member having a specific cross-sectional shape. For example, when cutting at the maximum diameter portion in a plane perpendicular to the long axis, the shape of the cut surface may be an ellipse, or may be a perfect circle. Good. Further, the coating member 20 is not limited to a member whose cut surface has a smooth ellipse or a perfect circle, and the cut surface has a polygon which has an extremely short side length and is substantially an ellipse or a perfect circle. Such a member may be used.

As clearly shown in the side view of FIG. 1B, the tip portion 22 of the inclined surface portion 21 is chamfered. The tip portion 22 is an end portion on the side opposite to the grip portion 20A, that is, on the lower side in the figure, and in a side view state, the substantially spindle-shaped peripheral surface of the coating member 20 and the inclined surface portion 21 form an acute angle. It is the end part on the side. The tip portion 22 is a boundary portion between the peripheral surface of the coating member 20 and the inclined surface portion 21, and has a narrow shape like a ridgeline of a mountain in this example. The chamfering process on the tip portion 22 is, for example, a process of forming an arcuate cross section with a radius of about 0.2 mm, but is not limited thereto.

On the other hand, the grip portion 20A has a shape in which the end portion 23 connected to the coating portion 20B has a cross-sectional area that gradually decreases toward the coating portion 20B. Further, the grip portion 20A has, for example, a columnar extending portion 24 fixed in the support member 10. The total length of the gripping portion 20A including the extending portion 24 may be appropriately set according to the length of the supporting member 10.

The cosmetic applicator 1 described above is used, for example, as shown in FIGS. 3 and 4. In this case, the cap 15 is used to apply lip cosmetics such as lipsticks and glosses, particularly liquid, paste-like or gel-like lip cosmetics, and closes the container body 30 containing such cosmetics. The cosmetic applicator 1 is attached to the supporting member 10. The state of this attachment is as shown in FIG. 1, and the extending portion 24 is fixed inside the support member 10. FIG. 3 shows a state in which the cap 15 is removed from the container body 30, and FIG. 4 shows a state in which the cap 15 is combined with the container body 30. In the former state, the coating member 20 is exposed on the tip side of the support member 10 of the cap 15.

As clearly shown in FIG. 4, the support member 10 to which the cosmetic applicator 1 is attached protrudes toward the cap open end side in the central portion of the cap 15. Therefore, when the cap 15 is screwed onto the male screw 31 formed on the mouth portion 35 of the container body 30 and is combined with the container body 30, the application member 20 of the cosmetic applicator 1 enters the inside of the container body 30. To do. At this time, if the cosmetic material M is stored in the container body 30, the application member 20 is immersed in the cosmetic material M. As a result, the cosmetic material M adheres to the surface of the coating member 20 including the inclined surface portion 21.

Thereafter, when the user applies the cosmetic material M to the lips or the like, the cap 15 is unscrewed and removed from the container body 30. Thereby, the support member 10 and the coating member 20 fixed thereto are pulled out from the container body 30. A claw member 32 is attached to the inner peripheral surface of the mouth 35 of the container body 30. Therefore, the coating member 20 that is pulled out is scribed at the annular inner end 33 of the claw member 32, and the excess cosmetic material M adhering to the coating member 20 is scraped off.

As described above, in the cap 15 that the user removes from the container body 30 and grips, an appropriate amount of the cosmetic material M is attached to the application member 20 at the tip of the support member 10. Therefore, the user can apply the cosmetic material M attached to the application member 20 to the lips while appropriately moving the gripped cap 15.

The application of the cosmetic material M at this time will be described in detail by returning to FIG. Since the inclined surface portion 21 formed on the coating member 20 extends in the region including the maximum diameter portion of the coating member 20 and extending from the portion toward the tip side, a large amount of the cosmetic M is applied to the expanded inclined surface portion 21. Can be attached. Therefore, the user can apply a large amount of cosmetics to the lips etc. at a time by using the inclined surface portion 21.

In addition, the portion that contacts the back side of the inclined surface portion 21, that is, the peripheral surface of the coating member 20 is a curved surface like the surface of a finger. Therefore, the user can attach the cosmetic material M to the curved surface and apply the cosmetic material M delicately, for example, by blurring it by thinly stretching it with a finger.

Further, as described above, the tip portion 22 of the inclined surface portion 21 which is the boundary portion with the peripheral surface of the coating member 20 has a narrow shape like a ridgeline of a mountain. Therefore, the user can attach a small amount of the cosmetic material M to the narrow tip portion 22 and delicately apply the cosmetic material M to the lips or the like. The inclined surface portion 21 serving as the application surface is formed on a part of the application member 20 which is essentially in the shape of a spindle. However, when applying the cosmetic material M, the application member 20 is unlikely to be easily deformed, so that stable use is ensured. You can get a feeling.

The tip portion 22 of the inclined surface portion 21 is chamfered as described above. Even if a small amount of the cosmetic material M is attached to the tip portion 22 and delicate coating is performed as described above, effective makeup cannot be applied if the attached amount is too small. On the other hand, if the above-mentioned chamfering process is applied to the tip portion 22, a sufficient amount of the cosmetic material M can be attached to the tip portion 22. Further, if the cross-sectional shape of the tip portion 22 is rounded by the chamfering process, it is possible to obtain a skin-friendly application feeling.

On the other hand, as described above, the gripping portion 20A has a shape in which the end portion 23 connected to the coating portion 20B has a cross-sectional area that gradually decreases toward the coating portion 20B. That is, the end portion 23 of the grip portion 20A has a partly thin shape. Therefore, when the cosmetic material M is applied, the thin portion causes "bend", which facilitates the application of the cosmetic material M.

The inclined surface portion 21 serving as the application surface may be a flat surface in order to obtain a good application feeling or to adjust the amount of the cosmetic M deposited, or it may be a concave surface or a convex surface as a whole. May be. Further, in such an inclined surface portion 21, a partially small concave portion or convex portion may be formed.

Further, in order to increase the amount of the cosmetic material M to be carried, at least a part of the application portion 20B may be subjected to a flocking process (electrostatic flocking process).

Next, with reference to FIG. 5, a cosmetic applicator 2 according to a second embodiment of the present invention will be described. Note that, in FIG. 5, elements equivalent to those in FIG. 1 described above are denoted by the same reference numerals, and description thereof will be omitted unless particularly necessary. Further, in the following, if there is a corresponding portion between the cosmetic applicator 1 and the cosmetic applicator 2 in FIG. 1, only the corresponding relationship will be described, and duplicate description will be omitted.

The cosmetic applicator 2 shown in FIG. 5 is basically different from the cosmetic applicator 1 of FIG. 1 in that the angle θ formed by the inclined surface portion 21 and the major axis of the application member 20 is made smaller. That is, in this embodiment, the angle θ is 9.8°. By doing so, the inclined surface portion 41, which is the application surface in the present embodiment, extends longer than the inclined surface portion 21 in the cosmetic applicator 1 of FIG. 1, so that a large amount of the cosmetic M is attached. Be advantageous.

The method of illustration in FIGS. 5A and 5B is the same as the method of illustration in FIGS. 1A and 1B. Further, the coating member 40, the grip portion 40A, the coating portion 40B, the inclined surface portion 41, the tip end portion 42, the end portion 43, and the extending portion 44 in FIG. 5 are respectively the coating member 20, the grip portion 20A, the coating portion 20B, and the slope in FIG. It corresponds to the face portion 21, the tip portion 22, the end portion 23, and the extending portion 24.

The cosmetic applicator 2 shown in FIG. 5 is different from the cosmetic applicator 1 in FIG. 1 in that the grip portion 40A has a flange 45 that projects radially outward. The collar portion 45 is located on the rear end side of the grip portion 40A (that is, on the end portion side opposite to the tip end to which the coating portion 40B is attached) with respect to the portion of the end portion 43 where the cross-sectional area is gradually reduced and which has the maximum cross-sectional area. ) Is formed. It should be noted that the above-mentioned "projected radially outward" means that the flange portion 45 extends radially outward from the center portion of the collar portion 45 in a plan view state (state viewed from above in FIG. 5), and the end portion 43 is cut off. It means that it extends to a position aligned with the outer circumference of the part having the largest area or extends to a position beyond the outer circumference. By providing such a collar portion 45, it is possible to prevent excessive cosmetic material M from adhering to the end portion 43 of the grip portion 40A. The reason why such an effect is obtained by the collar portion 45 is that when the coating member 40 of the cosmetic applicator 2 is made to enter the inside of the container body 30 as shown in FIG. Due to the presence of the portion 45, it is difficult for the cosmetic M to enter the narrowed portion of the end portion 43, and when the cosmetic applicator 2 is pulled out from the container body 30, the collar 45 serves as an eaves. It is considered that the cosmetic material M hardly accumulates in the end portion 43.

The cosmetic applicator 2 shown in FIG. 5 is different from the cosmetic applicator 1 of FIG. 1 in that the tip end portion 42 of the inclined surface portion 41 is not chamfered. That is, in the cosmetic applicator 2, the inclined surface portion 41 is formed so that the angle formed with the peripheral surface of the application member 40 does not form an acute angle, so that a relatively large amount of the cosmetic material M is originally provided in the tip portion 42. Can be attached.

The cosmetic M applied by the cosmetic applicator 1 or the cosmetic applicator 2 is not limited to the lip cosmetic, and the cosmetic applicator of the present invention applies other cosmetics such as a concealer. It can also be applied to do so. Further, the cosmetic applicator of the present invention is not limited to the form of being attached to the cap of the cosmetic container, and may be formed to be handled alone.
