Strawless drinking lid for a container

A method of making a strawless drinking lid for a container, comprising:

• providing a sheet of thermoformable polymeric material;
• and
• thermoforming the sheet to create a hollow body comprising:
• a mounting portion defining an outer perimeter;
• a perimeter wall disposed inwardly from the mounting portion, the perimeter wall extending upwardly relative the mounting portion and having an outer surface facing the mounting portion and an inner surface opposite the outer surface;
• a center portion extending inwardly from the inner surface of the perimeter wall;
• and
• a raised drinking portion extending upwardly from the center portion, the raised drinking portion having a front section and a back section with an upper surface therebetween, the front section of the raised drinking portion having a front edge proximate the inner surface of the perimeter wall, and the back section of the raised drinking portion having a back surface extending upwardly from the center portion,
• the raised drinking portion having a closed configuration with the upper surface undeformed and the front edge adjacent the inner surface of the perimeter wall, and the raised drinking portion having an open configuration when the upper surface is deformed downwardly to define an opening between the front edge and the inner surface of the perimeter wall.
