Description

  The present invention relates to a lip cosmetic applicator for applying lip cosmetics such as lipstick and gloss.

  In recent years, cosmetics for lips such as lipsticks and glosses that have a cosmetic effect that gives gloss to the lips and produces lips with a three-dimensional appearance have been widely preferred. Such lip cosmetics are often liquid, paste-like or gel-like, and have a relatively low viscosity, so that cosmetic containers can be reliably stored without leakage of the cosmetics, Moreover, since it is also excellent in portability, a cosmetic container comprising a container main body for storing cosmetics and a cap attached to the inside of the spatula-shaped applicator that can be inserted into the container main body to scoop up the cosmetics. Is often used.

  In such a cosmetic container, if more than necessary cosmetics are attached to the extracted applicator, it may interfere with the makeup operation, for example, the cosmetic may protrude from an unintended part when applied to the lips. Usually, a squirrel part is installed at the outlet of the container body to squeeze the applicator and scrape off excess cosmetics.

  However, it is difficult to adjust the amount of cosmetics to be scraped off with shigoki parts, and the amount of scraping varies depending on the angle and speed of the applicator when it is extracted from the container body. The cosmetics that are used are not necessarily in an appropriate amount, and there are cases where the finish of the makeup is not sufficient. Further, when the amount of cosmetics to be scooped up is small, it is troublesome in the makeup act and inferior in usability to repeatedly scoop up the cosmetics while inserting / removing the applicator into / from the container body. On the other hand, if the surface of the applicator is not sufficiently adhered to the lips, the cosmetic cannot be applied uniformly, and the cosmetic effect cannot be sufficiently obtained.

  Therefore, in the applicator for applying the cosmetic to the lips, the appropriate amount of the lip cosmetic can be surely scooped and the cosmetic applicator for lips can be spread evenly in close contact with the lips. Development is desired.

  The form of the lip cosmetic applicator of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows the structure of a cosmetic container assembled with the cosmetic applicator for lips of the present invention. The cosmetic container (11) is composed of a container body (12) and a cap (13) for filling the cosmetic. The cap (13) removes the cosmetic and applies the cosmetic to the lips. A material applicator (1) is provided. This cosmetic applicator for lips (1) has a support member (2) and an application member (3) joined together, and the end of the support member (2) to which the application member is not joined has a cap (13). It is joined to. The support member (2) and the application member (3) are joined together by a holding hole (5) provided at the end of the support member (2) with a holding part (4) provided integrally at the end of the application member (3). ) And fix it. Moreover, this cosmetics applicator for lips (1) is impregnated into the cosmetic filled in the container body (12) when the cap (13) is screwed into the mouth of the container body (12). Attached to the cap (13). The lip cosmetic applicator of the present invention can be used not only in a cosmetic container but also as an applicator for applying the cosmetic alone.

  For the application member (3), it is necessary to select a material having an appropriate elasticity in order to improve the feel to the lips and make the makeup operation smooth. Further, since it is a part that is always in contact with the cosmetic, it must be a chemically stable material that does not interact with the cosmetic. Therefore, the material forming the application member (3) is preferably an elastomer resin, and as such an elastomer resin, for example, a thermoplastic elastomer is preferable.

  The applicator member (3) has a width of about 3.5 to 9.0 mm, a length of about 12 to 18 mm, and a thickness of about 0.5 because of the ease of the operation of scooping out the cosmetic and applying it to the lips. Although it is preferable that it is -5 mm, it is not limited to this depending on cosmetics.

  A squirrel part (14) is installed in the outlet of the container body (12). When the lip cosmetic applicator (1) is pulled out from the container body (12), the support member (2) and the application member (3 Excess cosmetic material adhering to) is scraped off by the inner hole edge (15) of the swordfish part. The inner hole edge (15) of the squirrel part (14) has a circular shape having no directionality because the cap is rotated to pull out the lip cosmetic applicator. As the material of the squirrel part (15), an elastomer such as nitrile butadiene rubber (NBR) is generally used because it needs to have elasticity.

  The lip cosmetic applicator (1) includes a rod-shaped support member (2) for supporting the application member, and a substantially flat application member (3) extending from the tip of the support member (FIG. 1, 2), on the flat front and back surfaces of the coating member (3), center lines (O1, O2) intersecting the extending direction substantially perpendicular to the extending direction at different positions in the extending direction of the coating member extending from the support member Are formed as curved recesses (6a, 6b) each having a predetermined radius of curvature (R1, R2) with a center thereof as a center (FIG. 3).

  When applying cosmetics using the lip cosmetic applicator (1), the lip cosmetic applicator (1) is pulled out of the container body (12) and the extraneous material adhering to the surface of the application member (3). The cosmetic is scraped off with squirrel parts (14), and a certain amount of cosmetic carried on the surface of the coating member is applied to the lip cosmetic applicator (1) while keeping the coating member in close contact with the lips. To do.

  The lip cosmetic applicator (1) has a predetermined radius of curvature (R1, R2) on the flat front and back surfaces of the applicator member (3) with a center line intersecting substantially perpendicular to the extending direction as the center. Since each of the arc-shaped curved recesses (6a, 6b) is formed (FIG. 3), it is applied to the lower lip and the upper lip after being pulled out from the container body (12). Therefore, it is possible to reliably carry a necessary amount of cosmetic material, to make up the cosmetic material in the middle of the cosmetic operation, and to eliminate the operation of scooping the cosmetic material from the container body (12) many times. Further, since the curved recesses (6a, 6b) are shaped to be in close contact with the lower lip and the upper lip, the cosmetic can be uniformly spread while the surface of the application member (3) is in close contact with the lips.

  The curved recesses (6a, 6b) provided on the flat front and back surfaces of the coating member (3) are arranged at different positions in the extending direction of the coating member extending from the support member, so that the thickness of the coating member is uniform to some extent. (Fig. 3). Normally, the application member is manufactured by injection molding of synthetic resin, etc. However, if the application member is formed with a certain thickness, the entire application member can be elastic, and cosmetics can be applied to the lips. In this case, the application member can easily adhere to the lips and a uniform application state can be obtained, and the feel of the application member on the lips can be softened to improve the feeling of use during application.

  FIG. 2 shows an example of the application member (3) formed with a substantially uniform thickness, but the elasticity of the entire application member is adjusted by appropriately embedding portions other than the curved recesses (6a, 6b). You can also For example, FIG. 6 shows an example of the applicator member (3) in which the back side of the curved recess (6a) of the applicator member (3) is built up and this part is formed to be the same or slightly thicker than the tip portion (8). ing. As described above, it is preferable that the thickness of the application member is appropriately adjusted according to the viscosity or hardness of the cosmetic to be applied to obtain an application member that is most suitable for a cosmetic action.

  Further, since the curved recesses (6a, 6b) having an arcuate cross section extend substantially perpendicular to the extending direction of the coating member (3) extending from the support member (2), the curved recesses (6a, 6b) are formed on the lips. When applying to the lips with the lip cosmetic applicator (1) in hand and with the applicator member standing so that the tip of the applicator member (3) is in the upward direction The curved concave portions (6a, 6b) can be moved left and right along the lips while keeping the lips in close contact with the lips, and the cosmetic can be uniformly applied (FIG. 7).

  The radius of curvature (R1, R2) of the cross section of the curved recess (6a, 6b) can be appropriately set according to the viscosity of the cosmetic to be applied, the shape of the application member, etc. If it is a material, it is preferable that the radius of curvature (R1, R2) is 15 to 35 mm (FIG. 3). If the radius of curvature is less than 15 mm, the amount of cosmetic that can be scooped off becomes small, and it becomes difficult to sufficiently apply the cosmetic to the upper and lower lips. On the other hand, if the radius of curvature is larger than 35 mm, the amount of cosmetic to be scooped up is too large, and the curved concave portion is difficult to adhere to the lips, making it difficult to uniformly apply the cosmetic to the lips. Therefore, the curvature radius (R1, R2) of the curved concave portion is optimally 15 to 35 mm in order to sufficiently carry the cosmetic and to apply the cosmetic evenly in close contact with the lips. is there.

  The applicator member (3) extends inclining with respect to the support member so as to form an acute angle with the extension axis of the support member (2), and the flat surface of the applicator member facing the extension axis is the outer surface (3a). The coating member can be formed with the other flat surface located on the opposite side of the outer surface as the inner surface (3b) (FIGS. 2 and 3). Since the shape and size of the lower lip and the upper lip are different, it is preferable to provide an inclined angle on the flat front and back surfaces of the application member and use them separately for the application surface to the lower lip and the application surface to the upper lip. . Therefore, the flat front and back surfaces of the coating member are inclined with respect to the support member, and the flat surface of the coating member that extends at an acute angle with the extension axis while facing the extension axis of the support member (2) (3a), and the other flat surface located on the opposite side of the outer surface is formed as the inner surface (3b). If the outer surface (3a) is the application surface to the lower lip and the inner surface (3b) is the application surface to the upper lip, as shown in FIG. The cosmetics can be applied uniformly by performing the makeup operation while properly using the outer side surface and the inner side surface.

  Here, the inclination angle θ of the coating member (3) with respect to the extension axis (B) of the support member (2) is preferably 3 to 25 degrees (FIG. 3). If the inclination of the coating member is smaller than 3 degrees, the front and back surfaces of the coating member are difficult to adhere to the lips, and the outer side surface and the inner side surface cannot be distinguished from each other. It becomes difficult to use different surfaces. On the other hand, if the inclination of the application member is greater than 25 degrees, the inclination of the front and back surfaces of the application member is too large, making it difficult to adhere to the lower lip and the upper lip, making it impossible to uniformly apply the cosmetic. A makeup effect cannot be obtained. Thus, in order to obtain an excellent cosmetic effect by properly using the flat front and back surfaces of the application member and bringing them into close contact with the lower lip and upper lip, the inclination angle of the application member is optimally 3 to 25 degrees.

  As shown in FIG. 3, the curved recess (6b) provided on the inner surface of the application member can be arranged in the distal direction of the application member (3) than the curved recess (6a) provided on the outer surface. The curved concave portion (6a) provided on the outer side surface is more likely to be in close contact with the lower lip when positioned in the root direction (support shaft side) of the application member (FIG. 7 (a)), and the curved concave portion (6b) provided on the inner side surface. Is easier to adhere to the upper lip when positioned in the tip direction of the application member (FIG. 7 (b)), so that the curved recess (6b) provided on the inner surface is applied from the curved recess (6a) provided on the outer surface. By arranging the member (3) in the distal direction, the makeup operation can be performed more smoothly. In addition, by arranging the two curved recesses (6a, 6b) at different positions in the extending direction of the coating member extending from the support member in this way, the thickness of the coating member can be kept to a certain degree, The entire application member can be provided with elasticity, and the application member can be easily brought into close contact with the lips, and the feeling of use can be improved with a soft feel. The radius of curvature R1 of the curved recess (6a) provided on the outer side and the radius of curvature R2 of the curved recess (6b) provided on the inner side are the same, or the lower lip has a larger radius of curvature than the upper lip. , R1 is preferably larger than R2.

  The surface of the application member can be electrostatically flocked so that the cosmetic can be sufficiently carried (FIG. 5). By applying electrostatic flocking to the smooth surface of the application member, the cosmetic can be held between the flocks, and the cosmetic can be spread more uniformly. The fiber used for electrostatic flocking (floky process) is not particularly limited in terms of material and thickness, and is generally about 0.9 to 3.3 T in thickness, which is generally used as electrostatic flocking for cosmetic tools. (Decitex) made of resin such as nylon or polyester can be used. In addition, when the length of the fiber to be planted is 0.2 to 1.5 mm, the tip of the planted hair stands up toward the center of the radius of curvature in the curved recess, which makes it easier to carry cosmetics in the curved recess. . If the length of the fiber is shorter than 0.2 mm, the effect of carrying cosmetics by flocking is low, and if the length of the fiber is longer than 1.5 mm, the flocking becomes bulky and there is a merit due to the shape of the curved recess provided in the application member In addition to damage, repeated use makes it difficult for the flock to stand and reduces the amount of cosmetic material to be impregnated. Thus, it can be said that the fiber length is optimally 0.2 to 1.5 mm in order to sufficiently carry the cosmetic in the curved recess. In addition, by mixing a plurality of types of fibers having different thicknesses, lengths, materials, and the like, it is possible to improve the effect of supporting the cosmetic by improving the liquid content and the degree of standing of the flocking. Since it can be adjusted, the feeling of use can be adjusted.

  The front and back surfaces of the tip portion (8) of the coating member are centered on a center line that is substantially perpendicular to the extending direction at substantially the same position in the extending direction of the coating member extending from the support member (2). The curved bottom grooves (9a, 9b) each having a predetermined radius of curvature (R3, R4) can be provided (FIGS. 2 and 4). Thus, by providing curved bottom grooves (9a, 9b) on the front and back surfaces of the tip portion (8) of the coating member, the cross section of the projecting portion (10) has a semicircular shape with a small curvature radius (the curvature radius R5 is About 0.2 to 0.8 mm), it is possible to perform a fine makeup operation such as applying cosmetics along the lip contour using the protrusion (10). Furthermore, by providing the curved bottom groove (9a, 9b) at the tip (8) of the application member, the cosmetic can be carried in the curved bottom groove, and the cosmetic is interrupted when the cosmetic is applied at the tip. The cosmetic can be applied smoothly without any problems.

  If the radius of curvature (R3, R4) of the curved grooves (9a, 9b) is 0.1 to 3 mm and the surface of the coating member (3) is electrostatically flocked, the protruding portion (10) will be raised radially. Therefore, it is possible to obtain a gradation effect by blurring the applied cosmetic using the protrusion (10) (FIG. 4).

  In order to confirm the effect of the cosmetic applicator for lips of the present invention, the results of a confirmation test performed in comparison with a conventional applicator are described as examples.

  Cosmetics which can be carried when the lip cosmetic applicator of the present invention and the conventional applicator (FIG. 8) which does not have curved concave portions on the front and back surfaces of the applicator member are pulled out from the container containing the cosmetic. The amount of charge was measured and compared.

  As shown in FIG. 9, the lip cosmetic applicator of the present invention can carry 105% of the amount of the cosmetic with respect to the conventional applicator, and is an amount necessary to make up the lower lip and the upper lip. Confirmed that it can be scooped up.
