The TamperAlert Hinge™ protrudes outward when torn, and together with the "Do Not Purchase" message embossed on the lid, alert the customer that the container has been opened. The hinge remains attached to the container, for no loose plastic pieces. SafeSeal™ Snack Cups function as an easy to re-close and re-open, leak resistant two piece container once the hinge is torn. Has a 360 perimeter seal which preserves product freshness and prevents leaks and spills. Use with Dart clear cup inserts to add sauces, dips, granola or other enhancements to your grab 'n' go offerings.
