• a sifter, detachably disposed on the mouth, the sifter having a first sifter body and a second sifter body, a connecting portion being connected between the first sifter body and the second sifter body, allowing the second sifter body to flip relative to the first sifter body;
• wherein the first sifter body has a first bottom wall, a first annular wall around the first bottom wall, and a first compartment defined between the first bottom wall and the first annular wall, a peripheral side of the first annular wall having a first flange extending laterally and corresponding to the lip, one side of the first bottom wall, facing the second sifter body, has a recess, a first flat surface is formed on a bottom of the recess, a first annular surface is formed on a peripheral side of the recess, the first flat surface and the first annular surface are located at different levels and have a height difference, and the first flat surface is perforated with a plurality of perforations;
• wherein the second sifter body is detachably disposed in the first compartment, the second sifter body has a second bottom wall corresponding to the first bottom wall, a second annular wall that is around the second bottom wall and corresponds to the first annular wall, and a second compartment defined between the second bottom wall and the second annular wall, a peripheral side of the second annular wall has a second flange corresponding to the first flange, one side of the second bottom wall, facing the first sifter body, has a protrusion corresponding to the recess, a second flat surface is formed on an end face of the protrusion, a second annular surface is formed on a peripheral side of the protrusion, and the second flat surface and the second annular surface are located at different levels and have a height difference;
• wherein when the second sifter body is closed relative to the first sifter body, the protrusion is inserted into the recess, and the second flat surface is pressed against the first flat surface, thereby forming a first sealing configuration;
• the second bottom wall is pressed against the first bottom wall, and the second annular surface is pressed against the first annular surface, thereby forming a second sealing configuration;
• a sealing cap, detachably disposed on the container body and configured for covering an outer side of the sifter, an inner side of the sealing cap having a pressing portion, wherein when the sealing cap is coupled to the container body, the pressing portion presses the second flange and the first flange against the lip of the container body.
