ABSTRACT:
A stopper is provided which is adapted to be held in place in an opening in a molded thermoplastic container that is molded about the stopper in place. The stopper has a substantially cylindrical body portion with a planar end surface at one end thereof and a unitary skirt portion depending from the other end of the body portion. An annular flange, unitary with the body portion, extends laterally away from the body portion in one end thereof to define first and second peripheral flange surfaces and a lateral flange surface. The first peripheral flange surface is contiguous with the planar end surface and with the lateral flange surface. The first peripheral flange surface further is disposed at an angle with respect to the planar end surface and converges towards the second peripheral flange surface in a direction away from the body portion. The second peripheral flange surface is contiguous with the lateral flange surface and the skirt portion.
