The invention relates to a plastic collapsible storage and transport container comprising a bottom part (2) with four collapsible sidewalls (3, 4) arranged in an articulated manner on the bottom part (2). Two opposing first sidewalls can be detachably engaged with the two other opposing second sidewalls (4) The container (1) also comprises a cover (5) and means for sealing (56) the cover to the container in a fixed manner. The bottom part (2) formed by a bottom frame (15) and a bottom plate (16) comprises at least two inwardly open and outwardly closed recesses (19) along each frame side (17, 18), said recesses having lateral boreholes extending parallel to the frame sides (17, 18) of the bottom frame (15). Said recesses (19) are used to receive molded parts (21) formed on the first and second sidewalls (3, 4), provided with lugs (22) extending parallel to the lower edges of the sidewalls (3, 4). Said lugs (22) can be inserted into the lateral boreholes (20) of the recess (19) and rotated therein in such a way that they form a hinge-type connection between the bottom part (2) and the sidewalls (3, 4). The cover is formed by two cover halves (5) connected to opposite sidewalls (4) of the container (1) by means of cover hinges (7).
