Abstract
The present invention provides a stopper device comprising a stopper-support structure having a passage inside and a stopper accommodated in the-passage so as to block the passage but movably in the passage, as well as an apparatus containing the stopper device, used for mixing of two components. The stopper device can be penetrated with a connecting device with no edge and therefore generates no debris during penetration and reliably prevents leakage of container contents.
