There is provided a method for producing a musical and/or toy shaker made with a thermoplastic material. The shaker is injection or blow molded in the form of a substantially continuous body that defines an internal, hollow portion. In addition, the body defines a hole or vent that communicates with the hollow portion, thus allowing a fill material to be passed through the vent and deposited in the hollow portion. Significantly, the body in formed with a duct surrounding the vent. Upon filling the hollow portion, the duct is melted in order to seal the vent.
