摘要：The dispenser comprises a hollow body formed adjacent its upper end with aninward and downward annular flap. The method involves the molding of the body withthe flap inclined upward. A tool is inserted into the open end of the body to fold the flapdownward. In assembly, with the tool removed and the flap thus folded, the plungermoves past the flap so that the flap thereafter engages a shoulder on the plunger andforms an obstacle to the subsequent removal, accidental or otherwise, of the plunger.
