摘要
A food packaging solution features a food-containing tray to be frictionally retained within an outer sleeve. External flanges of the tray are each resiliently flexible from a normal default condition into a down-turned condition bent more downwardly away from the open top end of the tray than in the normal default condition, and the sleeve is shaped and dimensioned to accommodate the tray between the opposing side walls of the sleeve only when the flanges of the tray are in the down-turned condition. When received inside the sleeve, the resilient flanges of the tray bias themselves upwardly in a spring-like manner forcing their distal outer ends into tighter frictional engagement with the sleeve walls.
