Abstract:
A domed lid for a food container is configured for ease of engagement and removal from a container base The lid characteristically includes: (a) a dome portion with a top wall and a sidewall ; (b) a flange portion extending outwardly away from a lower portion of the sidewall; and (c) a tab portion extending outwardly from the flange. The flange portion is provided with a rim having a variable profile around the rim characterized in that: (i) the rim is provided with a securing undercut portion extending around the majority of its periphery adapted to secure the lid to an outer border of base and (ii) the rim has a pair of relatively passive engagement profile portions on either side of tab , extending to the securing undercut portion of the rim, the passive engagement profile portions are configured so that they are undercut less than the securing undercut portion of the lid, thereby facilitating engagement of the lid with, or removal of the lid from, base.
Embodiments of the invention provide an adapter suitable for use with cups and lids. In some embodiments, the adapter is designed so that a single lid with a predetermined diameter fits, by way of the adapter, with paper cups of different diameters. In some embodiments, an adapter including an inner diameter that corresponds to the upper diameter of the paper cup cooperates with the upper portion of the cup. The adapter also includes an outer diameter that corresponds to the predetermined diameter of the lid to ensure a secure fit between that particular sized cup and the plastic lid having a predetermined diameter.

Abstract:
This invention relates generally to lidded disposable pressed paperboard containers and more particularly to a disposable lid with an engagement profile particularly useful for paperboard containers comprising evert outer portions. The lid of the present invention provides a good fit for paperboard container bases having evert outer portions while still allowing the lid to be removed from the base without the need for excessive force. The lid profile is relatively insensitive to size variations of paperboard container bases having evert outer portions and allows for flexing of paperboard during application so as to provide an unexpectedly good seal so as to provide lidded, disposable paperboard containers.
