The following specification describes a stop boss formed on the handle of a pair by means of a pair of slides located behind a skirt wall of the pail with the handle passing through a slot in the skirt wall, which is closed by a flange wall formed by the slides. The slides are movably carried in guides by a ring member and are received in a recess of another ring member which conventionally forms the annular pail wall. The guides enable the slides to move laterally toward each other in response to downward movement of the carrying ring member, to define the cavities for forming the stop boss and the flange wall closing the skirt wall slot. On completion of the mold cycle and upward movement of the ring member carrying the slides, the guides move the slides laterally apart to release the stop boss and the flange wall. The slides are then moved from between the skirt and pail walls to enable the pail to be released from the mold.
