PROBLEM TO BE SOLVED: To increase strength of a bottom part of a coating inner container.SOLUTION: A resin coating inner container 1 comprises an opening 1OP formed of four side face parts 1SA, 1SB, 1SC, 1SD, and the opening 1OP is a substantially quadrilateral shape in plan view. Plural projection parts 2 arranged in a stripe pattern shape, are arranged on a surface 1BS of a bottom part 1B of the coating inner container 1 facing the opening 1OP in plan view. The bottom part 1B is inclined at a first inclination angle θ1, and is inclined upward, at a second inclination angle θ2 larger than the first inclination angle. As a coating amount in the coating inner container 1 is reduced, following to progress of a coating work, plural projection parts 2 arranged on a second bottom surface 1BBS are exposed, and form projection parts drawing a coating tool such as a roller. The stripe pattern shaped plural projection parts 2 achieve a further hard bottom surface by increasing thickness and weight of the bottom part 1B of the coating inner container 1, and have a function for reinforcement of strength of the bottom part 1B.SELECTED DRAWING: Figure 1 |
