Container having: - a base ; - a vertical axis which runs so as to be perpendicular to the base ; - a jacket which adjoins the base in an encircling manner and which at one end that faces away from the base has an encircling and outwardly projecting peripheral flange ; - an opening cross section which is defined by that end of the jacket that faces away from the base and which permits access to the respective internal volume of the container ; and - a cover which in the closing position thereof closes the opening cross section and which on peripheries is provided in an encircling manner with snap-fit hooks which are disposed so as to be distributed and each mutually spaced from the other; wherein the snap-fit hooks in the closing position of the cover engage in latching openings in the peripheral flange , which are adapted to said snap-fit hooks , on account of which a form-fit which prevents movement which is directed away from the base and parallel with the vertical axis of the container is formed, and wherein the cover in the closing position tightly closes the internal volume of the container , wherein at least one latching opening is disposed in each of four corner regions of the peripheral flange , wherein these latching openings when viewed in the plane of the peripheral flange at least in portions run so as to be curved or inclined in relation to both a transverse axis (Q) and a longitudinal axis (L) of the container , or are assembled from at least two straight portions which run so as to be mutually inclined, and wherein the associated snap-fit hooks are configured so as to be adapted thereto, wherein, when viewed in a plane of the peripheral flange , elongate snap-fit hooks and elongate latching openings adapted to the latter are provided, wherein an end of the container that faces away from the base is formed by an encircling sealing web , characterized in that the sealing web in the closing position of the container bears in a sealing manner on a seal which in the cover is located in an encircling sealing groove that is adapted to the sealing web , wherein the shaped latching openings have the effect that the cover, upon introduction of the associated snap-fit hook into the latching opening which is curved, inclined, or assembled from two portions, can no longer be displaced in the direction of the longitudinal axis (L) or transverse axis (Q) such that it is achieved that the remaining snap-fit hooks can make their way exclusively into the corresponding latching openings , wherein the plurality of "non straight" snap-fit hooks thus assume a guiding function for the orderly alignment and insertion of the remaining snap-fit hooks which are disposed so as to be parallel to the longitudinal axis (L) or transverse axis (Q). - a base ; - a vertical axis which runs so as to be perpendicular to the base ; - a jacket which adjoins the base in an encircling manner and which at one end that faces away from the base has an encircling and outwardly projecting peripheral flange ; - an opening cross section which is defined by that end of the jacket that faces away from the base and which permits access to the respective internal volume of the container ; and - a cover which in the closing position thereof closes the opening cross section and which on peripheries is provided in an encircling manner with snap-fit hooks which are disposed so as to be distributed and each mutually spaced from the other; <EOS>
