1. A container for centrifugation comprising:
a main body (100) including a first chamber (110) in which a material to be centrifuged is received, a second chamber (120) in which a suspended material centrifuged from the material in the first chamber (110) is decanted from the first chamber (110) and received and which is positioned on one side of the first chamber (110), and a coupling part (130) formed to surround the first chamber (110) and the outside of the upper end of the second chamber (120); and
a cover (200) which covers an upper portion of the main body (100) and forms a fluid communication path (P) of the decanted suspended material between the first chamber (110) and the second chamber (120),
wherein the inside of the first chamber (110) has a valve body (140′) which is disposed to linearly reciprocate in a longitudinal direction of the first chamber (110) to be positioned on a boundary layer between the centrifuged materials and have a through-hole (145′) formed on the bottom surface and through which the material to be centrifuged is separately moved,
the cover (200) is configured by a ring part (230) which forms the rim of the cover (200) and is formed to be coupled to the coupling part (130) at the rim of the cover, a recess part (220) which is connected to the inner side of the ring part (230) to be formed in a recessed shape, and a protrusion part (210) which is connected to the inner side of the recess part (220) and formed in a protruding shape to form the fluid communication path (P) so that the suspended material is discharged from the first chamber (110) to the second chamber (120),
in the protrusion part (210), an inlet port (212) is formed to protrude from the protrusion part (210) for injecting the material to be centrifuged to the first chamber (110),
the recess part (220) has an air vent for discharging inner air by injecting the material to be centrifuged to the first chamber (110) and a discharge port for discharging a suspended material introduced into the second chamber (120),
the ring part (230) includes an outer ring part (231), a planar ring part (232) connected to the outer ring part (231), and an inner ring part (233) which is connected with the planar ring part (232) and has a stepped portion, wherein a ring hook (231-1) is formed on an inner peripheral surface of the outer ring part (231), and
an outer end portion of the coupling part (130) has a coupling hook (131) which is extended upward and corresponds to an outer peripheral surface so as to be coupled with the ring hook (231-1) of the outer ring part (231),
wherein the valve body (140′) is configured by an inner bottom surface (143′), an outer bottom surface (141′) forming a lower surface of the inner bottom surface (143′), an inner surface (144′) connected with the inner bottom surface (143′), an outer surface (142′) forming the outer portion of the inner surface (144′) and connected with the outer bottom surface (141′), and the through-hole (145′) formed by passing through the inner bottom surface (143′) and the outer bottom surface (141′) to be formed in a cup shape as a whole, and
a foot plate (141-1′) protrudes from the outer bottom surface (141′), the inner surface (144′) has a first slope surface (144-1′) and a second slope surface (144-2′) formed sequentially from the lower portion to the upper portion for smooth movement of the suspended material, the outer surface (142′) has a larger diameter upward and is formed so as to be inclined upward, and the upper end of the outer surface (142′) has an outer surface minute protrusion part (142-1′) minutely protruding outward along the outer peripheral surface.
