REINFORCED NESTABLE CONTAINER

摘要

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.

1. A reinforced nestable container formed of a thermoformed material and able to withstand a high pressure processing, the container having an open end, a closed end, and a sidewall extending between the open end and the closed end and defining an interior, the closed end having a cone bottom comprising:
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, thereby 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.
