Plastic stackable crates for transportation and storage of goods, e.g. packages containing fluids and the like, and particularly for milk carton containers, comprising main and bottom portions, the former with front, rear and side walls that are open to the bottom, while the bottom portion is of the grating type, detachable and pivotable, allowing to be turned upwards and left in the upturned position so that the goods can be taken out through the tops of the empty upper crates when several of them are stacked up. Apertures on the front and/or rear walls of the crates, when stacked up, make a combined, almost full-height aperture which also allows the goods to be taken out sideways from the stacked crates.

A stackable plastic crate (20) for transportation and storage of goods, e.g. containers for fluids and the like, and particularly for milk carton containers, comprising, in combination: a main case (1) constituted by front (3), rear (4) and two side (5, 6) walls, said side walls being shorter than said front and said rear walls; a single detachable, pivotable bottom (2) of the grating (2a) type in said main case, which latter has an open top; said side walls having therein a pair of hinges (2c) for pivoting said bottom within said main case between a lowered, substantially horizontal closed position and a partly upwardly open position; a peripheral bottom border (12) below said walls and inwardly spaced from bottom edge sufaces (12a) of said walls; transversal (9b) and peripheral (10, 11) bracing and reinforcing ribs, the latter including a top border (10) above said side walls and said front and said rear walls and defining top edge surfaces (10a) thereof, said top border being somewhat wider than said bottom border so that said borders constitute stacking means cooperating with such borders of adjoining identical crates when the crate is made to form part of a vertically superposed stack (I, II, III . . . ); at least one of said front and rear walls having therein a pair of axially spaced, substantially rectangular apertures, the upper aperture having a U-shape and being bounded by a bottom edge and two spaced side edges, the spacing of the two side edges defining a discontinuity of the top border and the top edge surfaces, the lower aperture having an inverted U-shape and being bounded by a top edge and two spaced side edges, the spacing of the side edges of the lower aperture defining a discontinuity of the bottom border and the bottom edge surfaces; a narrow transverse wall section (3b) between said apertures in said one wall spacing said apertures apart and located about halfway the overall height of said main case; said apertures and said stacking means defining mating means for forming a peripherally enclosed and substantially rectangular access opening between two of the adjoining identical crates when the crate forms part of the stack, said upper aperture of a lower crate (I) and said lower aperture of an upper crate (II) from the two crates in the stack constituting together a contiguous, combined aperture (3e) defining said access opening, the opening the total height of which nearly corresponds to that of said main case; whereby goods are removable from the stack of crates laterally through said combined aperture when said bottom of a crate immediately above a combined aperture is in its open position.
