    [0001] The invention relates to a cosmetic applicator which is excellent in terms of the unloading stability of a liquid cosmetic product and also excellent in terms of the stability over time of a liquid cosmetic product and which makes it easy to observe the end of consumption of the liquid cosmetic product, regardless of whether the inside of a tank is visible or not and whether a party performing the application is of the ballpoint pen type or not. Until now, a device for redispersing the pigment is essential in an applicator in which a cosmetic product having a low viscosity and containing a pigment is loaded and retained. That is, it is a device in which an agitator such as a ball or stick for stirring or something similar is put into a reservoir of a cosmetic product, and, when a pigment contained therein tends to settle after not being used for a long time, the entire applicator is agitated until the stirrer rings as moving sufficiently, whereby the pigment can be redispersed (see for example JP-A 1993-7822 (claims, examples, Figure 1, etc.)). Similarly, the tip of the applicator above is provided with a tip effecting the application called a type of ballpoint pen in which a ball is pushed permanently forward in a ball holder and it is structured so that, when there is no more thrust, a liquid cosmetic product contained in the tank, leaves and is replaced by air. The above system encounters the problems that a cosmetic product seeps from the tip of the applicator, when the product has a low viscosity, and thus, a significant amount of the cosmetic product comes out unwanted, when there is no more thrust. By the present applicant, an applicator is disclosed which includes a mechanism in which, in place of the mechanism delivering the cosmetic product by replacing it with air in the applicator, as described above, there is provided a ball pen tip and a ball holder at the tip of a cylindrical reservoir, a cosmetic product and a stirrer in a reservoir, and a liquid follower at the back of the cosmetic product, where a space formed by the product The suinted cosmetic is enlarged by a follower movement (see, for example, JP-A 2007-272 (Claims, Examples, Figure 1, etc.)). In the applicator having the above mechanism, it is possible for the agitating ball 30 descends into the flexible follower when it is agitated, and for this purpose, a stop member is provided between the cosmetic product and the follower for stop the marble from going down there. [0005] In addition, there is an applicator in which a cosmetic product itself is gelatinized (provided with its structural viscosity) without installing an agitator to render a stirring superfluous and in which a follower is provided to arrange a mechanism close to a so-called gel ink ballpoint pen (see for example JP-A 2001-340131 (claims, examples, Fig. 1, etc.)). In the applicator having the above mechanism, a float (follower follower) is introduced from a back side of the follower to withstand a drop impact when the applicator falls with a back facing downwards, but what is involved is the problem that, when an accident occurs in which the float comes into contact with the surface of the wall of the cylindrical tank, air can enter and cause a negative effect on the stability over time of the cosmetic product. The object of the present invention is to provide a cosmetic applicator 15 which solves the problems of the traditional technologies described above, which is excellent in terms of the unloading stability of a liquid cosmetic product and excellent also in terms of stability over time of a liquid cosmetic product, while benefiting from the excellent materials of the traditional technologies, and which makes it easy to observe the end of use of the liquid cosmetic product, regardless of whether a reservoir is visible or not and if a party performing the application is ballpoint style or not.
