Abstract: A tamper-evident lid for use with a container to provide an assembly that is particularly suitable for distributing a food product contained therein. The lid includes a circumferential skirt with a plurality of tabs that are pivotal relative to the skirt out of a locked position. The tabs include side margins severably secured to the skirt, with pivoting of the tabs out of the locked position causing the side margins to be severed from the skirt. The tabs further include a locking element to engage the container and thereby prevent removal of the lid from the container when the tabs are in the locked position and permit removal of the lid from the container when the tabs are pivoted out of the locked position.

Abstract: A method for sealing a container comprising a cup and lid is disclosed. The cup has a lip with a raised sealing bead along its length. During sealing, the raised sealing bead compresses, thereby stretching the adhesive layer on the lower portion of the lid out of the way and forming a direct welded seal with the heat-resistant layer of the lid. The adhesive to either side of the sealing bead forms an adhesive seal between the lid and the remaining portion of the lip. This type of double seal is particularly effective in forming a durable, consistent seal when product is present on the lip of the container. The welded seal is also well suited to situations when the cup may be warped or the sealing bead is otherwise caused to be higher along some portion of its length than along other portions.
