  • DOUBLE WIPING STRUCTURE FOR TOOTHBRUSH-TYPE MASCARA WAND
    Publication number: 20200121060
    Abstract: A double wiping structure of a mascara wand provides an amount of mascara required to be applied to the eyelashes by causing a brush rod provided with a brush to be discharged along a ring member from a container so that mascara adhered to the brush rod is wiped using a first wiper and mascara adhered to the brush is wiped using a second wiper. The double wiping structure prevents mascara adhered to the brush from coming into contact with the inner surface of a wiper body and consequently prevents contamination of the inner surface of the wiper body due to the mascara by causing the ring member to be moved along the inner surface of the wiper body by pressure applied from the brush rod when the brush rod is introduced into and discharged from the container.
