The present invention relates to an apparatus equipped with a double roller unit for applying liquid material comprising: a main body which has a space inside to accommodate content, a coupling structure projecting upwards at the upper portion, and a first discharge hole through which the content is discharged at the upper portion; a roller supporting part disposed at the upper side of the main body, and having a second discharge hole communicating with the first discharge hole at the lower portion; a first roller part disposed in a rotatable manner at the roller supporting part so as to come in contact with the content discharged through the second discharge hole; a second roller part disposed at the side of the first roller part so as to be in contact with the first roller part, and coupled with the roller supporting part in a rotatable manner; and an inner cap coupled with the coupling structure of the main body, and having a through hole communicating with the first discharge hole. The roller supporting part comprises a plurality of supporting ribs projecting from the inner wall of the roller supporting part so as to come in contact with the outer circumferential surface of the inner cap. When the second roller part rotates, the first roller part rotates in connection with the second roller part, and transfers the contents discharged through the second discharge hole to the second roller part. According to the present invention, side-to-side shaking of the roller supporting part is minimized while the roller supporting part rotates because of the supporting ribs and a reinforcing rib. |
