- a) pre-forming the thermoplastic polymer composition into a pre-form at a pre-form temperature in a range of 180° C. to 300° C.;
- and
- b) drawn blow-molding the pre-form to form the disposable beverage container lid at a molding temperature in a range of 20° C. to 125° C.,
- wherein the formed disposable beverage container lid comprises:
- an interior cover including:
- a pair of openings to allow passage of the beverage in the beverage container through the interior cover,
- a reservoir bottom,
- a well portion extending downward from an edge of the reservoir bottom to form a well,
- a pair of retaining walls, each retaining wall extending upward from the edge of the reservoir bottom and flanking a side of the well portion and a side of one of the pair of openings, each said retaining wall extending inward past an edge of one of the openings of the pair of openings,
- an outer lip extending around an outer edge of the reservoir bottom, the well portion, and the retaining walls, the outer lip being formed to receive a rim of the beverage container, and
- an inner lip extending inward from an outer edge of the interior cover, the outer edge of the interior cover being sized to be received by the inner lip;
- an exterior cover having an outer edge, the exterior cover including:
- a flat portion extending inward from the outer edge of the exterior cover,
- a spout extending upward from the flat portion, and
- a pair of indentations;
- and
- a hinge connecting the interior cover to the exterior cover and foldable to orient the exterior cover over the interior cover,
- wherein the interior cover, the exterior cover, and the hinge are arranged such that, when the hinge is folded and the outer edge of the exterior cover is received by the inner lip of the interior cover, the spout is located above the well portion, and the pair of retaining walls of the interior cover is received by the pair of indentations of the flat portion of the exterior cover.
