Abstract
A squeeze bottle dispenser comprising a resilient squeeze bottle and a plug insert in the neck of the bottle. The plug insert receives a dip tube assembly comprising a dip tube and a short tube element adjacent the discharge orifice of the plug insert. The short tube element defines a passageway having a diameter of from about 0.014 to about 0.040 inch and is from about one-sixteenth to about 1 inch in length. The dip tube internal diameter is substantially greater than the diameter of the short tube element passageway. The short tube element may be inserted in the upper end of the dip tube or may abut the upper end of the dip tube. The making of the dip tube assembly comprises the steps of providing a short tube element and a long dip tube, and inserting the short element into the dip tube, with the upper ends of the element and tube being flush.
