In this assembly the spout attachment has at the top of its vertical wall a flat annular wiper flange having an upstanding sealing bead. The flange is clamped between the top of the mouth of the bottle and the undersurface of the closure so that the bead seals against the closure and no liner is necessary in the closure. To keep the attachment from uncontrolled rotation as the closure is screwed on and off, the vertical wall of the attachment is provided with a pair of horizontally aligned closely spaced lugs which straddle an inward protrusion in the mouth of the bottle.

In a molded spout component for a spouted molded bottle, the bottle having a normally upward circular mouth with threads formed on the outside thereof and a groove about the inside surface of the mouth with an inward protrusion in the groove, the spout being one piece and comprising a downward generally cylindrical outer wall, an inwardly directed annular bottom wall and a doubled-back upward cone-like spout wall having an opening at its upper end, the annular bottom wall being formed with a combined vent-and-drain-back passage outward and upward seal means about the per end of the outer wall adapted to rest on the top of the mouth of the bottle, the improvement of a pair of closely spaced outward lugs molded into the outer wall of the spout adjacent the upper end thereof, the spout adapted to fit snugly inside the mouth with the lugs snapped into the groove on opposite sides of the protrusion to thereby limit rotation of the spout with respect to the mouth of the bottle.
