An orifice reducer with crumple zones well suited for use with an extrusion
blow molded bottle having an uneven surface finish. The device includes a
circumferential wall having a number of vertically extending reduced
thickness regions, preferably spaced symmetrically about the
circumferential wall. The reduced thickness regions deform upon insertion
of the orifice reducer into the neck of a bottle to account for
irregularity of the surface finish of the bottle. This allows the orifice
reducer to be more easily inserted into standard extrusion blow molded
bottles.
