Abstract: Stackable container system (10), comprising a plurality of stackable elements (11,12), mutual releasable clamping means being provided between one element and the next, made up of hooking means (18,20) present near the top periphery of each stackable element (11, 12) and retaining means (21,22) of an upper element extending from at least one side of said upper stackable element (11,12) near a lower portion thereof, characterised in that said stackable elements are made up of container elements (11) and closing elements (12) of at least part of said containers (11).

Abstract: A drainage grid (12) for a dripping device (10) comprising a first flat portion of grid (14) to which a second flat portion of grid (15) is constrained, said second portion (15) can rotate around a first axis (21) defined by a border line between said first (14) and said second (15) portion. A third flat portion of grid (16) is constrained to the second portion (15), said third portion (16) can rotate around a second axis (22) defined by a border line between said second (15) and said third (16) portion.
