US Patent 11535428 Tamper evident reclosable container

A tamper-evident container has a lid with a rim with a bead mating with a groove in a base rim. The rim bead is interrupted by a tab wall which does not engage the base. The lid has a first flange portion which overlies a base flange. The base and lid first flange portions extend outwardly about the same amount. At the tab, a second portion of the lid flange extends substantially outwardly beyond the base flange. The flange second portion is connected to the first portion on both sides of the tab by weakened lines of material which extend cut lines through the tab front wall. The tab second flange portion is engageable to sever the weakened lines of material and pivot the tab upwardly to remove the lid, thus deforming it and evidencing tampering should the lid be replaced on the base. Base vents reduce ballooning when closed.
