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.
