The invention relates to a roof box arrangement for mounting on a vehicle, preferably a passenger car, which roof box arrangement has a container comprising an under part and an upper part, in conjunction with which the roof box arrangement has at least one open position for loading and unloading and one closed position for the storage of objects. A thermometer includes a temperature-indicating portion disposed within the mounting portion, an externally threaded portion extending downwardly from the temperature-indicating portion and having a bottom surface, and a sensor portion extending downwardly from the bottom surface. The PC Card includes one or more slots for receiving PC Card modules. A border includes indicia, both visual and tactile, to indicate the file and rank. The floating body transistor constructions can be incorporated into memory arrays, which in turn can be incorporated into electronic systems. The line of weakness is formed by a junction, by injection, of two layers of material defining respective parts of the surface area of the case.
