ABSTRACT:
A security stopper or other closure for a bottle comprises a valve which rests upon its seat except when the contents of a bottle are to be poured out through the stopper which thereby serves as a dispenser. The valve and seat arrangement is located at the lower portion of the plug-like body, the upper portion of which is provided from top to bottom with an upper baffle, an intermediate grill and a lower baffle to prevent access to the valve by a tool inserted through the pouring spout of the dispenser and thereby precluding refilling by dislocation of the valve.
