Abstract: A container and lid combination, typically thermoformed of plastic such as PVC, PS or PET wherein the lid is easily snapped closed onto the container, both initally and resealably, but cannot be removed therefrom without producing visible evidence thereof.

Abstract: A container is provided having a tray component and an independent cover component which is adapted to assume open and close modes with respect to the tray component. The components are interchangeable and each is provided with a recessed center portion having a base delimited by an angularly extending wall. An edge of the wall defines an open side. Each component also includes a laterally extending rim protruding outwardly from the wall edge. A predetermined first portion of the rim is provided with a first lock member and a predetermined second portion of the rim is provided with a second lock member. When the components are in the close mode, the first lock member of the tray component is in interlocking engagement with the second lock member of the cover component and vice versa.
