The tab fits into an aperture in the sidewall of the lid to hold the lid on the container body. The lid sidewall may be double layered. The locking aperture would be in the inner layer, and another aperture would be in the outer layer aligned with and providing access to the tab, allowing the tab to be pushed inwardly to unlock the lid.
