The technical result of the invention is in creating of a stopper of multiple use, simple construction, reliable at usage. The essence of the invention is in, that a stopper comprises connected with one another and capable of turning and axial displacement in respect to one another hollow portions (1, 2) for setting on a vessel and having a capacity, whereas the portion for setting on the vessel has a partition (3), in which an opening (4) with a valve (5) is made capable of hermetic separation or connecting of the stopper portions hollows by disposing the parts in respect to one another. According to the second embodiment the portion being set on the vessel has a partition (12), which has at least one opening (14). One end (15) of the portion having the capacity is open and its end is made of such a geometrical form and dimensions, that at turning and axial displacement of said portion is capable of tight fitting with the partition and hermetic sealing of the partition opening.</p> |
