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