Problems solved by technology

It is believed, if possible, that such a cover would be difficult to manufacture in a thermoforming process because of the sharply angled edges formed in the C-rail
And, to be sure, the covers cannot be stacked in an efficient manner
[0011] Despite the many options, existing and proposed disposable lids suffer from one or more of the following disadvantages: difficult and ineffective resealing; ineffective spill control; high material costs; excessive storage, packaging and shipping costs; Cannot be stacked in cups located on lid structure Medium

Abstract

The present invention relates generally to cup lids and, more particularly, to a thermoformed disposable cup lid with a drinking aperture and a closure panel displaceable along a generally radial direction between an open position wherein the aperture communicates with the interior of the lid and a closed position where the closure panel covers the aperture to reduce or substantially prevent spillage in use.
