This creation provides a kind of structure of container, and it includes a hollow cylinder, a piston portion, a push rod and an interconnecting pieces. Hollow cylinder includes an abutting end and an open end； Piston portion is movably set in what hollow cylinder； Push rod includes a shank, and one end of shank and piston portion can discretely be connected in the case where hollow cylinder has solution； Interconnecting piece includes a hollow adapter tube, and wherein one end system is connected with the abutting end of hollow cylinder. By push rod and the separable design of piston portion, structure of container entire length is reduced, structure of container is able to directly be placed in centrifuge, be centrifuged the blood extracted can in same container； By the design of interconnecting piece, export should not solution, retain desired ingredient, to reach the effect of same container is repeatedly centrifuged.本創作提供一種容器結構，其包含一中空筒體、一活塞部、一推桿以及一連接部。中空筒體包含一接合端及一開口端；活塞部可移動地設於中空筒體內；推桿包含一柄部，柄部的一端與活塞部在中空筒體有溶液的情況下，能分離地相連接；連接部包含一中空接管，其中一端係與中空筒體的接合端相連接。藉由推桿與活塞部可分離的設計，減少容器結構整體長度，容器結構得以直接置入離心機中，使抽取的血液可在同一容器中進行離心；藉由連接部的設計，導出不要的溶液，保留想要的成分，以達成在同一容器進行多次離心的功效。
