ABSTRACT:
A container, which may be injection molded in a single mold, includes a main body and a hollow cylindrical neck. The neck extends along a main axis and has a proximate end connected to the main body and an open distal end. The neck includes a generally cylindrical inner layer formed of a first thermoplastic material, a generally cylindrical middle layer located radially outward of the inner layer and formed of a second thermoplastic material having a greater heat resistance than the first thermoplastic material, and a generally cylindrical outer layer located radially outward of the middle layer so that the middle layer is at least partially sandwiched between the inner and outer layers. The outer layer is formed of the first thermoplastic material. An open end section extends from and is integral with the middle layer, is formed with the second thermoplastic material, and extends radially along the entire radial extent of the open distal end of the neck so that the entire open distal end of the neck is formed by the open end section.
