Abstract:
A cosmetic container including a wiper capable of avoiding a pumping phenomenon without deterioration in scraping effect is provided. A wiper fitted to an opening of a cosmetic container includes a plurality of tongue pieces having the same shape disposed evenly in a circumferential direction and extending downward inside the container. Regions of the tongue pieces adjacent to each other partially overlap in the circumferential direction and are joined integrally at the overlapping portion. A length of the tongue pieces in an axial direction gradually decreases from one circumferential side edge portion toward the other side edge portion. In the overlapping portion, a tongue piece side short in the axial direction is disposed inside so as to form a groove between the tongue pieces, extending in the circumferential direction, that allows for air to pass between outside and inside spaces of the wiper.
