US Patent 8034281 Dual container system

A container system is adapted to withstand impacts and features a first container having a first container body and a second container having a second container body. The second container defines a second body height and a second body wall thickness. A body recess is formed in the second container body for releasably engaging the first container body of the first container. A body recess defines at least one recess top and bottom corner and recess vertical edge having a recess top and bottom corner and vertical edge wall thickness, respectively, and which are intentionally thinned so as to have a thickness that is less than the second body wall thickness. The recess top and bottom corners and vertical edges are specifically configured to be deformable in response to an impact imposed thereagainst such that at least a portion of the impact shock is absorbed by the deformation in order to avoid rupture of the second container.
