Dispensing package for a pourable material having a bottle, a pour-back spout and a closure

摘要

A dispensing package includes a bottle, made of a blow-moldable plastic and having a neck finish, a pouring spout and a closure. An undercut groove in the interior of the neck finish holds a bead on the spout. The spout may have a pour-back design. Threading the closure onto the neck finish engages a top surface of the neck finish just above the groove with a closure-mounted seal. The groove may result from molding the neck finish against a pin which is withdrawn from the neck finish while the plastic is still warm but has enough plastic memory to result in groove definition following the removal. The bead of the spout may be press-fitted into the groove while the plastic is warm so that cooling-caused shrinkage firmly locks the spout in place.
