Description

  The present invention relates to a cosmetic applicator such as mascara. More specifically, the present invention relates to an applicator bar having an applicator on the tip side, and to a cosmetic applicator that wipes off the cosmetic adhering to the applicator by a wiping member and at the same time applies an appropriate amount of cosmetic adhering to the applicator.

  Mascara, eyeliner, lip gloss, and the like are used for applying liquid cosmetics contained in a container body to the application part at the tip of an application stick and applying it to eyelashes, eyelashes, lips, and the like. Conventionally, as shown in Patent Document 1, a torsion brush that forms a coating portion by spirally winding a central portion of a bristle with a core wire has been widely used for an applicator for mascara or eyebrow.

  The application part is immersed in the liquid cosmetic material in the container body to attach the liquid cosmetic material, and the extra liquid cosmetic material is adjusted to an appropriate amount by ironing with a wiping member. Therefore, the wiping piece constituting the wiping member is formed with a circular wiping hole so as to be in close contact with the application bar in order to extract the liquid cosmetic adhering to the application bar.

  On the other hand, as shown in Patent Document 2, a non-circular cross-sectional application portion that matches an applicator for mascara or eyebrow with a wiping member having a non-circular opening has been proposed.

JP 62-281903 A Japanese National Patent Publication No. 11-503345

  The application part shown in Patent Document 1 can be easily manufactured with few steps by twisting brush hairs uniformly arranged between core wires folded at the center.

  Patent Document 1 uses a torsion brush, and the application part has a circular cross-sectional shape, a truncated cone shape, or the like. In the case of Patent Document 1, the liquid cosmetic material excessively adhering to the application part is wiped by pressure from the outer periphery by the wiping member, so that the liquid cosmetic material is unevenly distributed on the center side of the application part where the pressure from the wiping part is difficult to be applied. Become. A large amount of liquid cosmetic material remaining on the center side has a risk of uneven application to the eyelashes due to a change in the direction of the application part or slight force.

  In Patent Document 2, the application part and the application rod are made non-circular, and the shape of the wiping part for wiping the application part is made the same non-circular shape as the application part. In Patent Document 2, the application part is non-circular so that it approaches the comb and can be used like a comb.

  However, when trying to combine a wiping part having a non-circular wiping hole, a non-circular application bar, and an application part as shown in FIG. 1, it is necessary to align the direction of the wiping part and the application part when inserting the application bar. , Capping becomes troublesome.

The present invention has been made in view of such problems, and its object is:
An object of the present invention is to provide a cosmetic applicator that can be applied without failure to the end of the eyelash by forming a strip in which the applicator portion extends linearly in the axial direction. It is another object of the present invention to provide a cosmetic applicator in which liquid cosmetic adhering to the application part is not unevenly distributed. In addition, such a cosmetic applicator can be provided at low cost.

  In order to achieve the above object, the cosmetic applicator of the present invention has a U-shaped groove formed in parallel with the central axis 79 from the tip of the application rod having a substantially circular cross section, and further along the bottom surface of the U-shaped groove. The application part is arranged in a strip shape.

  In other words, the wiping member includes the application rod that engraves a U-shaped groove in parallel with the central axis 79 from the tip to the center, and an application portion that is disposed in a band shape along the bottom surface of the U-shaped groove. As a result, the side of the application bar is slid and wiped, and the application part consisting of a plurality of brush bristles is pushed and bent into the U-shaped concave groove, and adheres to the application part by wiping along the side of the application bar. The cosmetics can be adjusted to a uniform and appropriate amount.

The cosmetic applicator of the present invention has the following effects.
That is, the brush bristles that form the application part are pushed into the U-shaped concave groove by the pressing force of the wiping part and are handled between the wiping hole and the outer periphery of the application bar to wipe away the excessively adhering liquid cosmetic. At the same time, the liquid cosmetic is uniformly distributed along with the bristles in the U-shaped groove. For this reason, when the shape of the application part is restored, the brush hair uniformly adheres the liquid cosmetic material to the outer periphery and the center part, thereby eliminating uneven application.

  In addition, since the U-shaped groove formed on the applicator bar maintains a constant shape regardless of external force, the liquid cosmetic contained in the U-shaped groove by handling by the wiping part is predicted by calculation at the design stage. Easy to turn on. Therefore, it is not necessary to adjust the expected amount of the liquid cosmetic adhering to the application part repeatedly by repeating the test.

  Next, the present invention will be described with reference to the drawings. FIG. 1 is an assembly explanatory view of a mascara container using the cosmetic applicator of the present invention. FIG. 1 shows a cross-sectional view of a mascara container, which is composed of a cylindrical container main body 3 that opens at the top and accommodates the liquid cosmetic 1, and a cap 5 that is screwed onto the container main body 3 and closed. An application rod 7 having a substantially circular cross section including an ellipse is suspended from the cap 5. A U-shaped groove 71 parallel to the central axis 79 is engraved from the tip of the coating rod 7 to the center. The bristle 91 is planted on the bottom 73 of the U-shaped groove 71 to form the application part 9. A neck tube 31 having a male screw portion 33 is fitted to the container body 3, and a wiping member 35 having a squeezing piece 37 is fixed to the lower portion of the neck tube 31. The squeezing piece 37 is formed so as to be in close contact with the outer periphery of the application bar 7, and the excess liquid cosmetic 1 adhering to the application bar 7 is squeezed off.

FIG. 2 is an explanatory view of an application part assembly example according to the present invention shown in FIG.
2A is a longitudinal cross-sectional view of the application part hanging from the cap 5, and FIG. 2B is a transverse cross-sectional view of the application part, showing an AA cross-sectional enlarged view of FIG. 2A. In FIG. 2A, the bristles 91 that are bundled small are driven into the bottom surface 73 of the U-shaped groove 71 and the tip end side of the application rod 7. At the tip of the applicator bar 7, the direction of the bristle 91 forming the applicator 9 is greatly changed and is directed in the axial direction. The direction of the bristle 91 is determined by directing a driving hole formed in the bottom surface 73 of the U-shaped groove 71 in an arbitrary direction.

  FIG. 3 is an explanatory drawing for extracting the application part in the container main body. The applicator 9 is disposed in a strip shape along a U-shaped groove 71 cut in parallel with the central axis 79 from the tip of the applicator bar 7. When the application part 9 is extracted and wiped away from the wiping member 35 in the direction of the arrow X1, the bristles 91 are greatly bent from the bottom surface 73 of the U-shaped groove 71 to the hair tips. Therefore, the application part 9 consisting of a plurality of brush bristles 91 is accommodated in the U-shaped groove 71 with a small force. The application bar 7 that houses the application part 9 in the U-shaped concave groove 71 can handle the excess liquid cosmetic 1 adhering to the surface by the ironing piece 37. However, the cosmetic material remains in the concave groove 71 of the application rod 7.

  In the above description, the application unit 9 is pulled out in the direction of the arrow X1. However, when the application unit 9 is inserted in the container body 3 through the inverted conical wiping unit 35 in the direction of the arrow X2, there is a difference in the squeezing force. Is the same. Alternatively, the wiping portion 35 may have the shape of the conventional wiping member 35 having a shape orthogonal to the central axis 79.

The application part 9 protrudes from a part of the surface of the application bar 7, and the amount of the liquid cosmetic 1 attached to the application part 9 is determined by the cross-sectional area of the U-shaped groove 71 formed in the application bar 7.
By providing the U-shaped groove 71 in the application bar 7, the amount of the liquid cosmetic 1 adhering to the application part 9 can be determined to some extent. Therefore, the amount of the liquid cosmetic 1 attached to the application part 9 can be calculated to some extent by repeated tests.

FIG. 4 is an explanatory diagram of an embodiment of another application unit according to the present invention. 4 (A) and 4 (C) show the cross sections of the application part 7 and the application part 9 as shown in FIG. 2 (B). FIG. 4A shows an example in which the bristle 91 is fixed to the U-shaped concave groove 71 using a stop line 99. The stop line 99 is made of a thin stainless steel round bar or a plastic round bar. As shown in FIG. 4A, a bristle fixing portion 51 is provided at the bottom 73 of the U-shaped groove 71 so as to be parallel to the U-shaped groove 71. The brush bristle fixing portion 51 is formed with a retaining portion 53 whose upper portion is slightly depressed. The bristle 91 that wraps the retaining wire 99 is fitted to the bristle fixing portion 51 by pushing the retaining portion 53 away. The bristle 91 to be fitted is sandwiched between the bristle fixing part 51 and the retaining line 99 and is pressed, and the brush bristle fixing part 51 is prevented from falling off and rising.

  FIG. 4B shows a longitudinal section of the coating part 7 and the coating part 9 including the central axis 79 so as to be orthogonal to the above-described FIG. FIG. 4B shows an example of fixing a belt-like twisted brush 93 in which brush hair is formed into a belt shape. As is well known, the twisting brush is one in which one wire is folded at the center and arranged in two, and is twisted with the bristle 91 interposed therebetween. In the present invention, a belt-like twisted brush 93 is used which is formed by leaving the brush hairs in the form of a belt in the axial length direction from a conventional twisted brush. The band-shaped twisted brush 93 has a fan shape centered on the core metal 98 or a brush shape with the core metal 98 on the back so that the core metal 98 can be disposed along the bottom surface 73 of the U-shaped concave groove 71. The base end portion 92 on the attachment side of the belt-like twisting brush 93 to the application rod 7 is attached and fixed along the central axis 79 in the U-shaped concave groove 71. Further, the distal end portion 94 is locked by bending to a metal core fixing hole 77 provided on the bottom surface 73 side of the U-shaped concave groove 71 to prevent the belt-like twisting brush 93 from being lifted.

  FIG. 4C shows an example in which the application part 9 is insert-molded into the U-shaped groove 71. In FIG. 4C, a through hole 75 is provided in the bottom surface 73 of the U-shaped groove 71. The through-hole 75 connects the U-shaped groove 71 of the application bar 7 to the removal prevention part 97 formed on the opposite side, and insert-molds the application part 9 into the U-shaped groove 71 of the application bar 7 so as not to fall off. The brush bristle part 95 that forms the application part 9 to be insert-molded is also squeezed by the ironing piece 37 and accommodated in the U-shaped groove 71 as shown in FIG.
