发明名称 Tamper evident container
摘要 An improvement to a container of the type that includes a vacuum formed transparent base and lid, the container having opposite sides that each forms a base flap (20) and a lid flap (22) that lie adjacent and parallel to each other, wherein the container indicates if it has been opened after a store clerk has loaded food into the container. An indicator sheet (34) lies between the base and lid and has cut-out characters (60) lying in holes (62) of a carrier (64), the carrier being bonded to the base flap and the characters being bonded to the lid flap. The container is opened by a person pulling up the lid flap, with the characters lifting out of their holes as they move up with the lid flap, and with the carrier that forms the character holes remaining on the base flap. When the lid is closed by pressing down the lid flap against the base flap, there will be some misalignment of the characters with the holes that they previously lay in, creating gaps that are readily noticeable. The gaps can spell much of a word such as“opened”.
