  • Patent number: 9364849
    Abstract: An applicator for cosmetics (in particular, eyeliner) and writing implements. The applicator includes an extrusion device that extrudes the content liquid to an applicator part. The applicator part has a conical part formed in an approximate conical shape. The conical part 31 has a plurality of thin disks arranged concentrically. The outside diameters of thin disks define a conical shape from a front end to a rear, and the thin disks is connected at their approximate center by an approximate cone or approximate cylinder. A plurality of grooves are formed in a front-to-rear direction of the applicator part. A liquid flow passage connected to a flow path is formed inside the approximate cone or approximate cylinder. Also, slits connecting the liquid flow passage and the grooves are formed on an outer side of the approximate cone or approximate cylinder.

  • Patent number: 9314810
    Abstract: An applicator includes a squeezer for pushing out a content liquid to an applicator part, and the shape of a content liquid delivering port of the applicator part is formed to be oval or rectangular while the minor axis and major axis on the delivery port side are specified to be 0.5 to 2 mm and 2 to 8 mm, respectively. In this applicator, large-sized particles can be delivered by enlargement of the bore inside the applicator part. Further, formation of an oval delivering port allows for drawing fine lines in the minor axis direction and thick lines in the major axis direction. Moreover, provision of small-diametric projections at the front end of applicator, enables drawing of long lines and retaining of the liquid cosmetic stored between projections.
