Abstract: Embodiments relate to a tamper evident lid formed of a thermoformed material for use with a container. The lid includes a round, substantially planar surface having a periphery defining a surface circumference. The lid further includes an engagement portion surrounding the periphery and extending there from. The engagement portion includes a friction fit portion extending generally upward from the planar surface; and a tear away portion removably connected to the friction fit portion and being generally parallel to the friction fit portion.

Abstract: Embodiments relate to a reinforced nestable container and a method of forming a reinforced nestable container able to withstand a high pressure processing. The container has an open end, a closed end, and a sidewall extending between the open end and the closed end and defines an interior. The closed end has a cone bottom including a first step that steps towards the closed end and forms a flexible point such that the base can flex and return to its original position and shape; a generally flat portion that extends towards the center of the closed end; a second step that steps towards the open end and in to an inner-profile having a first radius in one direction and a second radius in an opposite direction, forming an s-curve; at least one strengthening fillet; and a base plateau, whereby at least the s-curve formed by the first step, the flat portion and the second step spread tension such that the container can withstand pressure therein.
