Figure 6 illustrates an applicator head 112 in accordance with an alternative embodiment of the present invention. This applicator head 112 may replace the applicator head 12 of the applicator 10 described above.

In the following description, elements common to the embodiments of Figs. 1 and 2 are denoted by the same reference numerals.

The applicator head 112 includes an outer body 122 extending along a first axis 24. The outer shape of the outer body 122 is similar to the outer shape of the outer body 22 of Figures 1 and 2 including an outer flat surface 28 that is inclined with respect to the first axis 24. The flat surface 28 is perpendicular to the second axis 38 coplanar with the first axis 24 and forms an angle a (defined above) with the first axis 24.

The applicator head 112 includes three applicator elements 126, 127, 128 similar to the applicator element 26 of Figures 1 and 2. According to the transverse cross section of the applicator head, the three application elements 126 are arranged in a triangular shape. One of the application elements 126 is substantially contained within the symmetry plane of the outer body 22. [ The other application elements 127 and 128 are located on both sides of the symmetry plane.

Each of the application elements 126,127 and 128 is parallel to a first portion and a second axis 38 extending parallel to the first axis 24 in the same manner as the application element 26 of Figures 1 and 2 The second portion extending from the first portion to the second portion. The tip shaped end 40 of the second portion projects from the flat surface 28. The end portion 40 of the tip shape is positioned substantially at the apex of an equilateral triangle parallel to the flat surface 28. [

The outer body 122 includes an inner housing 146 that accommodates three dispensing elements 126, 127, 128. The housing 146 is bent to have a first straight portion parallel to the first axis 24 and a second straight portion parallel to the second axis 38. [

In other embodiments, the number of application elements may be four, five, or more in various configurations, such as the apex of a regular polygon.

Hereinafter, a realization process of the applicator heads 12 and 112 will be described. The application elements 26, 126, 127, 128, in particular the outer shell 60 and the projections 64, are formed by extrusion of molten polymer. As an example, this process may be performed by Teibow Co. Ltd., JPH04339696. The application element is then cut to an appropriate length and the first end 34 and the second end 40 are ground to a suitable shape. A linear application element is obtained.

According to a first embodiment, such as the embodiment of Figures 1 and 2, the two symmetrical halves of the outer body 22 are formed individually, for example, by injection molding. The applicator element 26 formed as described above is then inserted into the half-tube 46, which is the first half. Thus, the application element 26 takes a curved shape with the first portion 32 and the second portion 36 as described above. The second half of the outer body 22 is attached to the first half by welding or gluing. Thus, the applicator head 12 of FIG. 1 is obtained.

According to a second embodiment similar to the embodiment of Fig. 6, the application elements 126, 127 and 128 are provided in a mold having a curved shape, and the outer body 122, including the inner housing 146, (126, 127, 128). This molding includes a first step for forming the inner housing 94 surrounding the application elements 126, 127 and 128 and a second step for the outer part of the outer body 22, Can be carried out through a process. Thus, the applicator head 112 of FIG. 6 is obtained.

The applicator head 12, 112 is then attached to the container 14 to form the applicator 10. The amount of cosmetic composition contained in the container 14 is preferably selected such that the application element 26, 126, 127, 128 is immersed in the chemical composition. Preferably, each dimension of the applicator element and container 14 is selected such that the first end 34 is located in the vicinity of the bottom end of the container 14.

Hereinafter, a method of using the applicator 10 will be described. The user grasps the applicator head 12, 112, or the container 14 to bring the second end 40 of the tip shape of the applicator element into contact with its skin, preferably with its eyebrows. As the first end 34 of the application element is immersed in the chemical composition contained within the container 14, the internal path 62 of the application element is filled with the composition by capillary action. Thus, traces of the chemical composition are left by the tips of the respective applicator elements 26, 126, 127, 128 as they move the tip shaped end 40 along their eyebrows.

If desired, the user may press the container 14 to cause the fluid composition to travel through the internal path 62 to the second end 40 of the application element.
