ABSTRACT:
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.
