Abstract

Two embodiments of a dispensing stopper for bottles or the like having an improved arrangement for supporting the dispensing spout for movement between its open and closed positions. In each embodiment the supporting arrangement utilizes the surface which forms a closure for the pouring spout as a bearing surface to prevent misalignment and insure against leaks. The pouring spout is held in engagement with this combined closure bearing surface by an opposing bearing surface formed on an upper member of the closure. The pouring spout also has a pair of openings that extend through it and which cooperate with openings in the closure. One opening is used for dispensing and the other for venting. The dispensing opening is sized so that a straw may be placed through this opening to sip from the bottle, if desired. The venting opening extends to a lower level in the accompanying bottle than does the dispensing opening to aid in pouring under all conditions. In one embodiment the closure bearing surface and the corresponding surface of the spout are cylindrical segments and in the other embodiment these surfaces are spherical segments.
