【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 show a shadow applicator which is an embodiment of the cosmetic applicator of the present invention. FIG. 1 is a sectional view of the applicator, FIG. 2 is a perspective view of a nail member, and FIG. 3 is the same application. FIG. 4 is a cross-sectional view showing the state in which the tool projects the cosmetic, and FIG. 4 is a cross-sectional view showing the same tool in which the cosmetic is immersed. The parts having the same function as the conventional cosmetic applicator have the same reference numerals. Attached.

In the cosmetic applicator of this embodiment, the cylindrical rear extension engaging portion 33 of the fixed barrel 3 having the rod-shaped piston member 7 accommodated therein has the front engaging portion 53 of the rotating barrel 5. And is rotatably connected. Reference numeral 34 is a bulging wheel formed at the base of the extended engaging portion 33 of the fixed barrel 3, and the bulging ring 34 is engaged with a ring-shaped groove 54 formed inside the tip portion of the rotating barrel 5. However, the engaging root part has a coupling structure in which the O-ring 8 is interposed. Has been done. Incidentally, reference numerals 80 and 80 are caps, which are respectively removed when applying a shadow or when using a puff 82 provided at an end of the fixed barrel 5.

Next, the fixed cylinder 3, the rotary cylinder 5, and the piston member 7 will be described in detail. A cylinder 31 having a vertical groove 36 is formed in the fixed cylinder 3, and a fin portion 76 projecting from the piston member 7 inserted in the cylinder 31 engages with the vertical groove 36. Relative rotation between the piston member 7 and the fixed barrel 3 is prevented. Further, the cylinder 31 communicates with the front end opening 30 of a fixed cylinder having a smaller diameter than the cylinder diameter, and the front end of the fixed cylinder 3 is formed in a stepped taper shape which is tapered toward the front.

A male screw portion 73 is formed on the rear portion of the piston member 7, and the male screw portion 73 is screwed with a female screw portion 57 formed on the inner peripheral surface of the rotating cylinder. Therefore, when the rotating cylinder 5 is operated to rotate, the piston member 7 that is prevented from rotating with respect to the fixed cylinder 3 moves forward and backward in the cylinder 31. In the cylinder 31, a highly flexible cosmetics mounting cylinder 22 having a crayon-shaped solid cosmetics 66 loaded therein is housed so as to be slidable in the front-back direction in the cylinder. The front end portion 71 of the piston member 7 is inserted into the cosmetic mounting cylinder 22, and the front end portion 71 is in close contact with the rear end of the crayon-shaped solid cosmetic material 66. A reduced diameter portion 77 is formed behind the tip portion 71 of the piston member 7 in the mounting cylinder, and the claw member 44 is attached to this reduced diameter portion. As shown in FIG. 2, the claw member 44 is formed by bending a rectangular thin metal plate into a cylindrical shape, and has a branch spring-shaped claw 40, which is cut and raised at three circumferential positions on the outer side. It is protruding. The claw 40 of the claw member 44 is in pressure contact with the inner peripheral surface of the mounting cylinder 22, and when the piston member 7 advances, the claw can slide forward relative to the inner peripheral surface of the mounting cylinder, so On the other hand, the crayon-shaped solid cosmetic material 66 can be extruded. On the other hand, when the piston member 7 retracts, the branch spring-like claw 40 bites into the inner peripheral surface of the mounting cylinder, and the pawl cannot slide rearward relative to the inner peripheral surface of the mounting cylinder. The cylinder 22 is integrated through the claw member 44 and retracts.

Further, the inner diameter of the front end opening 30 of the fixed cylinder is formed to be substantially the same as the inner diameter of the cosmetics mounting cylinder 22, and a step 32 connected to the opening 30 is provided on the front end side of the cylinder 31. It is provided. Therefore, when the piston member 7 moves forward, the mounting cylinder 22 contacts the step 32 and is prevented from moving forward, and the piston member moves forward while rubbing the inside of the mounting cylinder 22 to push the cosmetic material 66 forward. As a result, as shown in the cross section in FIG. 3, the cosmetic material projects from the opening 30 in proportion to the amount of rotation of the rotating cylinder 5. The cosmetic may be applied by projecting it by a length suitable for application. When the cosmetic 66 is to be drawn into the opening 30 of the fixed cylinder 7 after application, the rotary cylinder 5 can be rotated in the opposite direction so that the mounting cylinder 22 and the piston member 7 can be moved as described above. The cosmetic 66 is retracted as a whole, and the cosmetic 66 is drawn in as shown in the cross section of FIG.

As described above, in this embodiment, the soft and brittle solid cosmetic material 66 is loaded into the flexible cosmetic material mounting cylinder 22 and housed in the cylinder 31, so that even if the applicator is dropped, The cushioning action of the mounting cylinder 22 does not break the cosmetic material 66. In particular, in the prior art, it can be said that the cosmetic is easily broken because it is supported only by the tip end portion of the piston member. However, in this embodiment, the cosmetic 66 is supported by the entire mounting cylinder 22, so that the surroundings of the cosmetic are It can be said that there is no play and it is less likely to break. Even if the cosmetic material 66 is broken, the cosmetic material 66 is filled in the mounting cylinder 22 without any gap, and therefore the broken part is retained in the mounting cylinder 22 without falling off from the mounting cylinder 22. Therefore, it can be used in a folded state.

Although the above-mentioned embodiments have been described with reference to a shadow applicator using a crayon-shaped soft solid cosmetic, a solid cosmetic applicator in the form of a stick made by solidifying powder, and other cosmetic applicators Can be similarly applied.

[0014]

[Effect of the device]

 As is clear from the above description, according to the present invention, since the solid cosmetic is loaded in the flexible cosmetic mounting cylinder having the cushioning effect, it has an effect that it is difficult to break even if it falls.
