<p>A stopper assembly for sealing an opening of a vessel has a threaded body having a tapered head; an elastic jacket fitted over a portion of the body; a retention housing fitted over the body and jacket, the retention housing retaining the jacket from lateral displacement there through; and a turning nut attached to the retention housing and threaded to the body. A user inserts the stopper assembly into the vessel opening, holds the retention housing stable, and turns the turning nut causing travel of the threaded body through the retention housing and deformation of the elastic jacket against the tapered head, deformation thereof directed radially outward to make peripheral contact with the inner surface of the opening affecting a seal of the opening.</p> |
