This creation provides a kind of container bottle, and it includes an ontology, a top cover, a bottom cover and an interconnecting pieces. Ontology includes storage tank on one, on an opposite what the lower storage tank of storage tank and one sets neck part on what between storage tank and lower storage tank； Wherein descending storage tank includes a piston piece, is the bottom end that lower storage tank is movably closed along lower storage tank long axis direction； Top cover system is connected with the top of upper storage tank； Bottom cover system is connected with the bottom end of lower storage tank； Interconnecting piece includes a connecting tube and a stopper section； Wherein one end system can be connected connecting tube with communicating with neck part； Stopper section system is separably connected with the other end of connecting tube. This creation can slowly rotate the piston piece for raising the lower storage tank of ontology by bottom cover, and the blood layer to be separated can be accurately exported by interconnecting piece, reduce the effect of pollution occurs to reach.本創作提供一種容器瓶，其包含一本體、一頂蓋、一底蓋以及一連接部。本體包含一上儲槽、一相對於上儲槽的下儲槽以及一設於上儲槽與下儲槽之間的瓶頸部；其中下儲槽包含一活塞件，其係沿著下儲槽長軸方向可移動地封閉下儲槽的底端；頂蓋係與上儲槽的頂端相連接；底蓋係與下儲槽的底端相連接；連接部包含一連接管以及一止擋部；連接管其中一端係與瓶頸部可相通地相連接；止擋部係與連接管的另一端可分離地相連接。本創作藉由底蓋可緩慢旋轉推升本體的下儲槽的活塞件，並藉由連接部可精準地導出欲分離的血液層，以達成降低汙染發生的功效。
