Abstract
A container has a lid () that can be opened only by lifting and pulling a pull tab (), with lifting of the pull-tab resulting in an evident change. The pull tab () is held down by attachment (interference fit, weld, glue) to a lid surface () by a hold-down () that is joined to the pull tab by a pair of bridges (). When the pull tab is lifted, the bridges are broken. Thereafter, the pull-tab springs up slightly from the lid plane, under the force of one or more spring walls () and a hinge (), which makes it evident that the container has been opened.
