Abstract
This invention provides a carrying case made up of two sections of molded plastic which are identical except at their outer edges which meet when the case is closed. One edge includes a tongue with reinforcing ribs which enters a groove in the outer edge to engage a gasket and form a fluid seal as well as strengthening the case. Nothing penetrates the wall of the case, the latches being connected to supports spaced outwardly from the case wall. Sockets on the bottom of the case receive spaced support members projecting from a luggage cart, and can receive connecting elements to enable the cart to carry more than one case. The sockets also can receive wheel units so that a single case may be mounted on wheels, or a plurality of cases may be connected and supported on a set of wheels. The case includes integral feet on the bottom wall to support it, and bosses on the inner walls for connecting items to the interior of the case.
