Non-refillable pourer fitment

Abstract

There is described a non-refillable pourer fitment for the neck of a container comprising inner and outer parts captively attached to each other, a valve member located and movable in a longitudinal bore in the inner part and the outer part being formed with a longitudinal bore at its inner end and a dispensing aperture at its outer end, the longitudinal bore in the outer part varying in radius along its length from a portion of relatively large radius to a portion of relatively small radius, an obturator disc intermediate said portion of relatively small radius and said outer end having a radius greater than said relatively small radius. An inwardly extending peg on the obturator disc suitably controls the limit of movement of the valve member, and the obturator disc is preferably attached through spaced frangible stays to an annular ring adapted to fit tightly within the entrance of the bore of a container to which the fitment is fitted.
