The second half portion further includes a plurality of second supports formed in the second wall and located within the second interior recess. Each first support has a first longitudinal axis and is aligned along a common first axis which intersects each first longitudinal axis normally within and defining a first common plane. Each second support has a second longitudinal axis and is aligned along a common second axis which intersects each second longitudinal axis normally within defining a second and common plane. The first and second planes are parallel and offset in the open position and aligned in opposition in the closed position such that each first support engages each said second support in mating contact. A load applied to the case in a closed position is distributed among the first and second supports and the first and second mating rims, resulting in a protective zone defined by the first and second interior recesses.
