Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a manufacturing method of a mascara brush,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing apparatus and a manufacturing method of a mascara brush, and more particularly, to a manufacturing apparatus and a manufacturing method of a mascara brush produced by injection-molding a synthetic resin chamber used as a mascara brush together with a mold.

In general, mascara refers to the type of cosmetics used by women, and refers to the use of brushes to apply various colors of lashes to the eyelashes to enhance the appearance of the eyes. The mascara includes a container for storing the mascara liquid, a handle for opening and closing the container, a bar support protruding to the lower portion of the handle, and a brush formed on the support bar. And the mascara liquid is embedded in the brush by separation.

The mascara brush corresponding to the structure consisting of such a brush and stalks has a volume (volume) effect on the eyelash according to the length and shape of the hair, curl (curl) It is made to suit various functions such as long lash (long lash effect) and clean (eye lash effect).

Such a mascara brush must be applied uniformly to the eyelashes of the mascara having a viscosity, and the combing function of the brushes must also be accompanied so that the eyelashes do not stick together.

The mascara brush serves to fix the eyelashes in various shapes by using the mascara liquid. However, even if the position of the brush is regular, the brushing effect of the mascara is deteriorated. In addition, even in the case of the integrated mascara brush, it is difficult to make an irregular brush. Also, there is a problem that the manufacturing cost is high because a plurality of brushes are assembled to make an irregular brush.

In addition, the conventional mascara brushes are formed of long bristles and irregularly arranged bristles. However, in this case, since the brushing function of the bristles is insufficient, the mascara liquid applied to the eyelashes often coagulates to a certain portion, There was also a problem that the aesthetic sense of the eyelashes was rather hindered.
