Abstract
A needle connecting portion of a syringe which includes a drug accommodating chamber accommodating a first component is arranged opposite to a takeout port of a hermetically closed container which includes a container chamber accommodating a second component. The syringe is connected to the container through a connector so as to be movable in mutual proximity and adapted to be separable from the connector. There is provided a communication passage capable of communicating the drug accommodating chamber with the container chamber. The communication passage is cut off by a closure member arranged between both of the chambers. The syringe and the container chamber are moved in proximity to each other, thereby displacing the closure member so as to open the communication passage. An injector of the present invention is compact in shape but can surely retain sterility while being stored and surely mix both of the components accommodated therein through a simple operation just before administration. Further, it can prevent the sharpness of an injection needle from being damaged at the time of a mixing operation and easily remove a syringe after the mixing operation.
