Abstract
Abstract A casing comprising a shell which has a transverse cross section in the form of an inverted square bottom "U". The bottom panel closes a part of the space between the ends of the arm of the "U" opposite to the top of the "U" and a back panel closes part of the space between the arms of the shell. The bottom panel and back panel do not extend to their common boundaries and a compartment panel is engaged between the back panel and the bottom panel.
