Abstract
A tamper-evident tab construction for a thermoformed package. In one embodiment, the package includes top and bottom parts with overlapping tabs. The top and bottom parts may include locking tabs that interlock with one another and provide a structure for holding the package while it is being opened. The top part may also include a pull tab located proximate the locking tabs. The pull tab is configured to provide a structure for pulling the top part away from the bottom part to open the package. The pull tab may be joined to the top part by a small land of material that is configured to deform when the package is opened. As a result, the pull tab may remain at an angle after opening to provide a visual indication that the package may have been opened or tampered with.
