A funnel for use in connection with reusable plastic bottles or containers includes a body portion and a spout portion extending from the body portion to a lower open end. The spout portion is formed of downwardly extending inner and outer portions in spaced apart relation from one another to define a gap therebetween sized for receiving an upper portion of a fill spout of the plastic bottle. The outer portion has an interior surface facing the inner portion. A lower portion of the interior surface has an inwardly upwardly tapered portion adapted for receiving an outwardly extending portion of the fill spout in pressing engagement therewith to allow inward compression of the outwardly extending portion against the interior surface.
