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.
Claims6
An applicator comprising:
- an applicator part having a mechanism for delivering or applying a content liquid;
- a reservoir filled with the content liquid;
- and
- an extruder having a mechanism of pushing out the content liquid to the applicator part, and
- wherein a flow passage that connects between the applicator part and the reservoir is formed, thereby pushing out the content liquid inside the reservoir, and the content liquid passes through the flow passage communicating between the applicator part and the reservoir, thereby being ejected out from the applicator part, and
- wherein the shape of the content liquid delivery port of the applicator part is oval or rectangular, and 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, and
- the content liquid is a liquid cosmetic that has a viscosity (25 deg. C.) at a shear rate of 7.68 S−1 in an EMD type viscometer, falling within the range of 250 to 1,000 mPa·s.
