<p>A casing has rectangular base and cover with side walls and joined by a hinge at one end. The cover has a shorter part adjacent the hinge connected by a second hinge to a longer part. The cover and base side walls at the hinge end are oblique so that the cover can be turned to an extreme position where it projects below the base, when the longer part can be turned in the same direction. When folded, the longer cover part underlies the base and has an end formation interlocking in the base underside to hold the case in the open position. The casing is pref. of polypropylene and is made integrally with reduced thickness living hinges. Rubber feet are pref. located on the base opposite the hinge end, and on the cover adjacent the second hinge.</p> |
