Embodiment approach 1
[0069] The following experimental manner was used to evaluate whether the user can use the cosmetic material remaining on the upper surface of the dipping member with the puff next time when the user uses the cosmetic with the dipping member with the puff.
[0070] When the impregnated article whose surface was not debossed (Comparative Example 1), the impregnated article whose surface was debossed by pressing (Comparative Example 2), and the impregnated article whose surface was debossed by laser beam processing (Comparative Example 3) When the pressing was repeated three times, the amounts of cosmetic materials remaining on the upper surface of the impregnated piece were compared with each other. Hereinafter, the experimental method is explained.
[0071] Place the puff to be applied with the cosmetic material on a press to press the sample under the conditions of the same depth, the same area and the same force, and dip the cosmetic material into the dipping piece of the sa...
Embodiment approach 2
[0079]In the impregnated article whose surface was not debossed (Comparative Example 1), the impregnated article whose surface was debossed by pressing (Comparative Example 2) and the impregnated article whose surface was debossed by laser beam processing (Comparative Example 3) After impregnating with the cosmetic material, 20 females aged 20-30 were allowed to use each impregnated piece with a puff for 6 weeks. The use feel of the cosmetic materials in the above cases was compared using qualitative data, and the average values are shown in Table 2 below. Evaluation is based on the ease of discharge of cosmetic materials and consistency of cosmetic convenience, and the evaluation indicators are as follows
[0080] (0-1: very poor, 1-2: poor, 2-3: fair, 3-4: good, 4-5: very good)

Embodiment approach 3
[0087] As described in Embodiments 1 and 2, the dipping member whose surface is debossed by laser according to the present invention exhibits good performance in terms of the discharge amount of cosmetic material and the consistency of cosmetic convenience.
[0088] Therefore, when processing a dip whose surface is debossed by laser according to the present invention, the most suitable width of the dimple pattern is determined by forming various widths w and various depths d in the surface of the dip by using a laser. w and depth d, the cosmetic material is then impregnated into the impregnated piece. At 0.4kgf / cm 2 Press the dipping piece under the same pressure to measure the amount of cosmetic material remaining on the upper surface of the dipping piece, in g.
[0089] table 3
[0090]
[0091] The amount of the cosmetic material remaining on the upper surface of the impregnated member was measured while changing the width w in a state in which the depth d of the laser...
