PURPOSE: A resin made container is provided to discharge almost all of liquid inside the container, thereby drastically reducing the amount of the remaining liquid compared with an existing container. CONSTITUTION: A resin made container includes a main body(10) and a concave part(50). The main body integrally comprises a bottom plate(20), a cylindrical body part(30), and a top plate(40) closing the upper end of the body part. The main body has a pipe(71) inserted inside the main body through the main outlet(45) opened on the top plate. The center of the concave part is not placed on a virtual axial line extended from the center of the main outlet in the height direction of the container. A groove part(60) on the bottom plate is formed into a gutter reaching the concave part. An annular part downwardly faces from the outer periphery of the bottom plate, and protrudes to a height lower than the lower side of the concave part. The concave part is formed at the center of the bottom plate. |
