Abstract

A dispenser for a container having a pouring spout being integral with a spout portion and being disposed a retaining wall. The pouring spout of the dispenser is configured to allow orientation specific stacking whereby a spout portion is stacked onto a previously formed spout portion to form a stack of spout portions being aligned in the same direction. The dispenser includes an integral flow opening formed through an underside of the floor between the retaining wall and the pouring spout. The flow opening is coplaner with a horizontal plane through a juncture of the neck and the shoulder of the container and provides a channel through which the contents of the container can flow unobstructedly between the shoulder of the container and the lower end of the spout portion, which diminishes the amount of residual contents left within the container.
