Abstract
A bottle closure device having a stem member with an enlarged top portion, a collar resiliently biased away from the top portion, a retainer member on the end of the stem, and an O-ring between the retainer member and the collar. When the end of the stem is placed within the mouth of a bottle, the biasing means acts to cause the retainer member to press the O-ring radially outward against the collar to form a fluid-tight seal with the mouth of the bottle.
