Abstract: A modular structure (10, 20) for containing articles, fluids or persons includes a plurality of elements (1, 13, 15) of plastic or composite material, coupled together along their end edges (26), mechanical fixing elements (23) and fluid seal members (43) being provided along those edges (26). The coupled elements (1, 13, 15) include at least one element (1) having a curved surface, the fluid seal members (43) being positioned on the inside of the modular structure (10, 20) in receiving seats (40) provided within an inner wall of the structure.

Abstract: A cup-like container, doubling as a sealing cap is disclosed for application to cans for soft drinks and the like. The cup-cap combination consists of a cup element rotatably mounted, directly of indirectly, on the rim of the can's lid and having a base aperture that can be positioned in juxtaposition with the opening in the lid, so as to allow the pouring of the contents, or away from said opening, so as to seal the can and prevent the spillage of the liquid. The cup element, thus, permits the consumption of the contents without resting one's lips on the rim of the can and allows the preservation of the contents, once the can has been opened.
