A dispensing device to be fitted to the top of a container and to be used to dispense heavy or viscous fluid from the container. It is a unitary structure that comprises generally a spout having a fluid passageway, a rod extending through the center of the spout, and a skirt bounding the base of the spout. The rod is joined to the inner wall of the spout by a relatively thin rectangular brace. The rod is generally cylindrical and has chamfered ends. An annular, curved member is formed inside the skirt and extends away from the spout to form a bottomless bowl portion interconnecting the spout passageway to form a continuous fluid passageway. The rod provides additional surface area for the liquid to cling to while it is being dispensed and also delays venting as the container is righted after the desired amount of liquid is dispensed, thereby preventing drippage. In addition, the bottomless bowl prevents clogging because it causes the liquid in the passageway to be pulled back from the spout into the container.
