Patent Summary
A plastic drinking container comprises a cup with a vertically oriented opening and a drinking lid configured to close said opening, wherein the cup and lid are welded together at the cup opening. In one embodiment, the cup features a bead—optionally with a right-angled triangular cross-section—at the outer edge of the cup flange to serve as weld metal, enhancing weld stability. The lid may include a lid flange and a collar extending partially into the cup. A film may close a drinking opening in the lid prior to welding, potentially featuring a tab for hygiene protection. The assembly may be produced via ultrasonic welding to ensure a flush, material-efficient seal and improve recyclability by utilizing uniform materials.
