Abstract
A container which indicates if the lid () has been opened after a clerk loaded food into the base () and closed the lid. The base and lid each has a trapping portion () and a pull-open portion () with a tear-tab, or tear -open barrier (). To close the lid, a clerk projects a tab () on the pull-open portion of the lid through a slot () in the pull-open portion of the base, and then presses down the entire trapping portion of the lid into the trapping portion of the base. The lid cannot be lifted up because the tear-open barrier () forming the top wall of the slot lies over the tab. To open the container, a person tears the barrier (, FIG.) along a tear line () extending from the slot () to the outer edge () of the base, or the person tears the tab to leave a short tab part that clears the barrier. The tab has a partially vertical stiffener () to prevent radially inward tab movement through the slot.
