Abstract
A thermoformed container system with a tray and a lid mounted on the tray, that includes special structures to help two or more containers to stand on their bottom edges when nested together, even though each individual container would be too unstable to stand in isolation. Alternative embodiments of the invention include a product case pack comprising at least two containers with product inside each container, and a method of retail sales display of two or more containers, where the containers are adapted to stand on their bottom edges when nested together.

A thermoformed container system comprising:
- a forward container and a rear container, each container made of thermoformed plastic and comprising a tray and a lid mounted on the tray, the container having a bottom edge;
- wherein the tray of the forward container has a bottom wall, a rear wall, and a top wall, wherein the bottom wall and the rear wall meet at a tray bottom rear corner, and the top wall and the rear wall meet at a tray top rear corner;
- wherein the lid of the rear container has a lid bottom edge, a bottom sealing rim portion adjacent to the lid bottom edge with a bottom sealing rim inside wall adjoining a central portion of the lid of the rear container, a lid top edge, and a top sealing rim portion adjacent to the lid top edge with a top sealing rim inside wall adjoining the central portion;
- wherein the tray of the forward container includes a first engagement structure that exerts a downward force met by an upward force from a second engagement structure on the lid of the rear container, and wherein the tray top rear corner does not engage the top sealing rim inside wall portion when the forward container and the rear container are nested together with the first engagement structure engaged with the second engagement structure;
- whereby the forward container and the rear container are adapted to stand on their bottom edges when nested together;
- and
- wherein the first engagement structure is an inverted shelf located on the tray bottom rear corner.
