The invention relates to a plastic container having a tamper evident lid and methods therefor, and particularly to a plastic container having a two-component pull-tab attached to part of the lid at its edge which is used to pull the lid off the container, where the pull-tab has a frangible break line where the act of pulling the pull-tab breaks an outer section away from an inner locked down tab, and once the frangible section is broken, provides evidence that the container was opened, since both parts of the pull-tab are now separated and the outer one bent upwards at an angle.

Pull-tab tamper evident container

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.
