A tamper evident package for perishable foods such as dairy products. A container which holds the food has an outwardly rolled rim. A skirted lid covers the container and has a peripheral flange overlying the container rim and a downturned skirt which is pressed inwardly beneath the rim to initially secure the lid on the container. Cuts are formed through the flange and separated by frangible webs to provide a line of detachment permitting the skirt to be torn away. The lid can be initially removed only by breaking at least one of the webs, and the condition of the webs thus provides an indication of whether or not the package has been opened. The package is formed by filling the container, applying the lid, pressing the skirt of the lid inwardly beneath the container rim with a heated forming head, and using die mounted heated blades to make the cuts.
