Abstract
A tamper resistant package for foods and other materials includes a container and a plug closure having a side wall and a flange spaced outwardly from the side wall. A detachable tear strip on the upper edge of the container is initially heat sealed to the edge of the flange. When the tear strip is detached, the heat seal ruptures to release the closure. The closure can thereafter be applied to cover the container with the upper edge of the container sandwiched closely between the closure wall and flange.
