Easy open, tamper evident envelope

摘要

An easy opening, tamper evident package has a package body with a mouth opening to receive materials. A closure flap extends from the package body next to the mouth opening. The closure flap has an inner surface which faces and overlaps an edge portion of the package body when the closure flap is fully extended to close mouth opening. An adhesive closure is permanently adhered to the inner surface of the flap and has an adhesive surface which adheres to the edge portion, at least when said closure flap is fully extended over said mouth opening and pressed against said package body. A break-away region is defined in the package by perforations through the package body near the mouth opening. The adhesive closure overlaps the break-away region, at least when the closure flap is fully extended over said mouth opening to close the mouth so that the overlapped break-away region is subject to tear forces applied to the package to separate the closure flap from the adhered edge portion when the package is opened.
