Micro pump vessel

A micro pump vessel composed of an outer vessel (10) on one side of which a button (11) is formed and an outer vessel lid (20) which is hinge-coupled to one side of the outer vessel (10) to be opened and closed, comprising:

• an inner vessel (30) provided inside the outer vessel (10);
• an inner vessel lid (40) coupled to the inner vessel (30) at a center of which a cosmetic suction hole (41) is formed;
• a micro pump (50) installed on an upper portion of the inner vessel lid (40) to pump cosmetic contents;
• a circular plate-shaped discharge plate (60), which is inserted and seated on the top surface of the inner vessel lid (40) with the micro pump (50) therebetween to discharge and accommodate the cosmetic contents discharged from the micro pump (50) onto the top surface thereof;
• a circular plate-shaped member (70) seated in a central groove (61) of the top surface of the discharge plate (60) and having, at an upper surface, a radial groove (71);
• a discharge film (80), which is a circular plate-shaped film to cover the entire top surface of the discharge plate (60) and has a plurality of cosmetic discharge holes (81) so as to correspond to the radial groove (71) of the circular plate-shaped member (70);
• a ring-shaped fixing member (90) configured to fix an edge of the discharge film (80) to the discharge plate (60) and allow a user to make contact with the discharge film (80) using a puff (P);
• a first piston (100) of a cylindrical member which is inserted to a lower surface of the inner vessel lid (40) and coupled to be in close contact with the inner circumference of the inner vessel lid to sweep down the cosmetic contents in the outer vessel (10), the first piston (100) having a cylindrical hole (103) and a close contact plate (104) protruding downward from an outer circumference of the first piston (100), wherein the first piston (100) is in contact with the cosmetic contents;
• and
• a second piston (110) having a columnar projection (112) that is constructed to be inserted into the cylindrical hole (103) of the first piston, the second piston (110) configured to be inserted to a lower portion of the first piston (100) to sweep down the cosmetic contents in the outer vessel (10) and exhaust them, wherein the second piston (110) is in contact with the cosmetic contents,
• wherein the cylindrical hole (103) is formed on an upper surface of the first piston (100) and the columnar projection (112) is formed on an upper surface of the second piston (110), wherein the columnar projection (112) is constructed to be inserted into the cylindrical hole (103), wherein when a volume of the cosmetic contents is reduced, the first piston (100) is lowered together with second piston (110), and
• wherein when the cosmetic contents are continuously discharged, the second piston (110) is lowered separately from the first piston (100) to exhaust the cosmetic contents.
