摘要: A tamper-evident closure for a wide mouth container. The member has central panel and downwardly opening rim cavity encircling the adapted to receive therein top of food is defined by pair upstanding, radially spaced skirt segments connected at their respectrive upper edges segment. outer one adjacent lower edge thereof inwardly projecting circumferentially extending first flange snugly fit under frictionally engage lip on In addition, also outwardly second contiguous with oriented below flange. plurality generally inverted V-shaped are integrally between each set mutually circumferential ends least have wall from respective walls extend inclined upwardly toward other integral connection forming an apex. Each plural apexes defines stress concentration structure material so that lifting force applied flanges will cause break only apexes.
