The mold has a main body portion that defines a forward end from which extends a sloped shoulder portion, a neck portion, and a stem element. Between the stem element and the neck portion, there is a provided a re-entrant surface which forms a sharp edge and an angle with respect to the outer, main surface of the neck portion. The mold is used in a dip-molding process for producing a dispensing container that has a frangible portion that is broken away during first use, which frangible portion is formed by the re-entrant surface.
