  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS.

  As shown in FIG. 1, the applicator 1 includes an applicator main body 2 and a cap 3. At the tip small diameter portion of the applicator main body 2, a male spiral 4 is provided on the outer peripheral surface, while a base portion of the brush holding portion 5 is fitted and fixed inside, and a brush 6 is inserted into the holding hole of the brush holding portion 5. It is fixed. The brush holding portion 5 has a tapered outer surface that gradually reduces the outer diameter toward the tip. As shown in FIGS. 1 and 2, the cap 3 has a bottomed cylindrical shape with one end opened and the other end closed, and a female helix 7 that can be screwed into the male helix 4 is disposed near the open end. It is provided on the inner circumference. The applicator main body 2 and the cap 3 can be attached and detached by the male and female spirals 4 and 7. And in the attachment state of the said applicator main body 2 and the said cap 3, a mutual axis line corresponds.

  As shown in FIGS. 1 and 2, the cap 3 includes a coating liquid storage portion 8 that stores a coating liquid (not shown) that is a cosmetic with high viscosity or is easily separated, and the coating liquid storage portion. 8 has a tapered inner surface whose inner diameter is gradually reduced from the open end side toward the coating liquid container 8 side, and the outer peripheral surface is in close contact with the inner peripheral surface of the cap 3. The guide member 9 is provided. Further, the cap 3 has a tapered inner surface that is located on the side of the coating liquid container 8 of the guide member 9 and is fitted and fixed between the outer peripheral surface of the guide member 9 and the inner peripheral surface of the cap 3. A wiper member 11 made of a flexible silicon material having a wiper hole 10 at the tip is provided. A plurality of grooves 3a extending in the axial direction are formed on the inner peripheral surface of the cap 3 corresponding to the coating liquid storage portion 8, and these grooves 3a are removed from the mold when a synthetic resin cap is molded. It acts as an anti-rotation.

  As shown in FIGS. 1 and 2, a cylindrical brush cover 12 is provided on the cap 3 on the side of the coating liquid container 8 of the wiper member 11 so that the outer peripheral surface thereof is in close contact with the inner peripheral surface of the cap 3. . As can be understood from FIGS. 2 and 3, the brush cover 12 includes a closing plate 14 provided with an insertion hole 13 in which the distal end portion of the wiper member 11 corresponds, and the coating plate 8 side from the closing plate 14. There are three partition plates 15 extending toward. Each side edge of the partition plate 15 extends into the insertion hole 13. When the cap 3 and the applicator main body 2 are mounted, the tip of the tapered outer surface of the brush holding portion 5 is close to the tapered inner surface of the guide member 9, and the brush 6 connects the guide member 9 and the wiper member 11 together. As a result, the tip portion protrudes from the wiper hole 10 and is located at the center of the insertion hole 13 in the brush cover 12.

  Also, as shown in FIGS. 2, 4 and 5, a stirring member 18 having a cylindrical shape and having three projecting shafts 16 and 17 at the upper and lower ends is disposed in the coating liquid storage unit 8, and each projecting shaft is provided. 16 and 17 are round bar shapes with rounded ends, and each projecting shaft 17 is thicker and longer than each projecting shaft 16. The number of projecting shafts 17 provided on the opening end side of the cap 3 of the stirring member 18 is the same as the number of partition plates 15 of the brush cover 12, and the projecting shafts 17 are located in the spaces between the partition plates 15. Each enters and can come into contact with the closing plate 14. Further, each protruding shaft 16 provided on the closed end side of the cap 3 has a contact area with the cap closed surface that is reduced by contact of each tip surface with the cap closed surface, and the viscosity of the cosmetic to be stored is high. However, the agitation member 18 is prevented from sticking to the cap closing surface, and can be reliably moved in the coating liquid storage unit 8. The stirring member 18 is made of PET, which is a hard synthetic resin having a sufficiently higher specific gravity than the coating liquid that is a cosmetic material housed in the coating liquid container 8. The stirring member 18 shakes the applicator 1 and moves the inside of the coating liquid storage unit 8 in the axial direction, thereby causing the viscosity of the lame-containing liquid cosmetic that is the coating liquid stored in the coating liquid storage unit 8. This is for agitation and homogenization of cosmetics which are expensive or easily separated.

  Then, the usage aspect of the applicator 1 comprised as mentioned above is demonstrated below. First, in the cap mounting state (screwed state) shown in FIG. 1, the applicator 1 is swung in the axial direction, and the stirring member 18 is moved between the cap closing surface and the closing plate 14 of the brush cover 12 in the coating liquid storage portion 8. The coating liquid (not shown) in the coating liquid storage unit 8 is circulated through the stirring member 18 and stirred to make the coating liquid uniform. At this time, each projecting shaft 17 of the stirring member 18 enters the brush cover 12, but comes into contact with the closing plate 14 outside the insertion hole 13, so that it does not contact the tip of the brush 6. On the other hand, since the application liquid in the application liquid storage part 8 is guided in the direction of the insertion hole 13 by each partition plate 15 of the brush cover 12, the application liquid adheres to the tip of the brush 6.

  Next, when the cap 3 and the applicator main body 2 are unscrewed and the cap 3 is removed, the tip of the brush 6 passes through the wiper hole 10 so that the excess coating liquid is removed. Then, the brush 6 is pulled out with a proper amount attached. The brush 6 is used to draw the eyeline. However, since the projecting shafts 17 of the stirring member 18 do not contact the tip of the brush 6, the tip of the brush 6 does not scatter and a desired thin line can be drawn. it can.

  After the application is finished, the brush 6 at the tip of the applicator main body 2 is inserted into the cap 3 from its open end, and the male spiral 4 reaches the female spiral 7 and the male and female spirals 4 and 7 are screwed together. 3 and the applicator main body 2 are rotated relative to each other so that the applicator main body 2 and the cap 3 are in the mounted state shown in FIG. At this time, since the inner peripheral surfaces of the guide member 9 and the wiper member 11 are tapered, even if the tip end of the brush 6 contacts these inner peripheral surfaces, the guide member 9 and the wiper member 11 are guided toward the axis and the tip end of the brush does not come apart. .

  In addition, this invention is not limited to the said embodiment at all, For example, the coating liquid to apply may be other cosmetics not for eyelines. Also. The number of the partition plates 15 of the brush cover 12 and the projecting shafts 17 of the stirring member 18 is not limited to three, but may be plural, but 3 to 5 is preferable. Further, the number of the other projecting shafts 16 of the stirring member 18 is not limited to three but may be plural, and it is not necessary to be the same number as the projecting shafts 16. Furthermore, the material of the stirring member 18 is not limited to polyethylene terephthalate, but may be a synthetic resin having a sufficiently higher specific gravity than the cosmetic material stored in the coating liquid storage unit 8.
