Abstract
A thin walled container of the type used to package dairy products such as yogurt, cottage cheese and other products is provided with an out-turned serrated container lip surrounded by an outward-spaced tamper-evident band, the lower edge of which is connected to the container by plural frangible bridges. The closure has a flange having an in-turned locking bead which engages the container lip and is held in place by the tamper-evident band. To open the container, the tamper-evident band is torn away by breaking the bridges, whereupon the closure may be separated from the container lip.
