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.
