Abstract
A tamper-evident rigid plastic food container system wherein the outer periphery of the mating surfaces of the lid and tray are permanently bonded together after the food product has been placed in the tray, a set of perforated rows at an inner periphery, the interconnect of which needs to be torn into order to open the lid. Intentional, inadvertent or malicious ingress into the container can only be made by tearing at the perforations thereby evidencing the potential tampering and contamination of the packaging contents. The lid and tray edges may further include mechanical interference fits, including snap-fit grips that may be of the releasably lockable kind to permit sealing, release and re-sealing multiple times without deterioration in reliability, and which can further prevent or minimize leakage of liquid food product.
