Patent number: 9708106Abstract: A container which includes a base (12) that can hold food and a lid (14) that closes on the base, which clearly indicates if the lid has been opened after a clerk loaded food into the base and closed the lid. The base and lid each have trapping portions (20, 22) and pull-open portions (24, 32) with a tear-tab, or tear-open barrier (80). To close the lid, a clerk projects a tab (30) on the pull-open portion of the lid through a slot (26) 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 (80) forming the top wall of the slot lies over the tab. To open the container, a person must tear the barrier so he/she can pull up the tab 30 and open the lid. The fact that the barrier has been torn is obvious.Type: GrantFiled: September 12, 2014Date of Patent: July 18, 2017Assignee: Pactiv LLCInventor: Terry Vovan
